Methods. Male diabetic (alloxan, 60 mg/kg i.v., 10 days) and nondiabetic mice were supplemented with cholecalciferol for seven days. e following parameters were determined: serum levels of 25-hydroxyvitamin D, phosphorus, calcium, urea, creatinine, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, red blood cell count, white blood cell count (WBC), hematocrit, hemoglobin, differential cell counts of peritoneal lavage (PeL), and bronchoalveolar lavage (BAL) fluids and morphological analysis of lung, kidney, and liver tissues.

Relative to controls, cholecalciferol supplementation increased serum levels of 25-hydroxyvitamin D, calcium, hemoglobin, hematocrit, and red blood cell counts and decreased leukocyte cell counts of PeL and BAL fluids in diabetic mice. Diabetic mice that were not treated with cholecalciferol had lower serum calcium and albumin levels and hemoglobin, WBC, and mononuclear blood cell counts and higher serum creatinine and urea levels than controls.

1 Introduction

Type 1 diabetes mellitus (T1D) is an autoimmune disorderthat causes destruction of pancreatic 120573 cells and insulitisresulting in loss of insulin secretion [1]

Several studies have demonstrated that diabetic individu-als with uncontrolled hyperglycemia may experience weightloss uncontrolled immune response hematological alter-ations and lung liver and kidney injuries [2 3] In additionrenal impairment in diabetes may affect the metabolism ofurea creatinine [4] hemoglobin (Hb) [5] albumin [6] andvitamin D [7 8]

Anemia is defined as a decrease in the amountof hemoglobin (Hb) or the number of red blood cells

(RBC) in the blood It is a common complication in patientswith diabetic kidney disease and it increases mortality indiabetic individuals but its mechanism of action is still notclear [9]

Albumin is the major plasma protein and plays a criticalrole in maintaining tissue oncotic pressure and in the trans-port of substances such as vitamin D into the bloodstreamStudies have suggested that hepatic albumin synthesis andsecretion are reduced in diabetic rats [10]

Vitamin D is a hormone obtained from the diet andorby endogenous synthesis The vitamin Dmolecule is hydrox-ylated twice once in the liver by the enzyme 25ndashhydroxylaseand once in the kidney by the enzyme 1120572ndashhydroxylase toform calcitriol (125(OH)2D) which is the form of vitamin

D that interacts with vitamin D receptor (VDR) to performits biological activity [7]

The classic activity of calcitriol is to regulate bonemetabolism by maintaining a balance between calcium (Ca)and phosphorus (P) concentrations [8] Studies have reportedthat vitaminDmay affect the course of T1D by immunomod-ulation [11] Although the mechanism of action is stillunknown serum 125(OH)2D levels appear to modulate thelevel of systemic cytokine production and to increase whiteblood cell (WBC) count [12 13]

Although vitamin D supplementation is an importantaid in clinical practice few studies have demonstrated theeffects of vitamin D supplementation on the course of T1Din humans and animals In addition vitamin D supple-mentation studies are often contradictory due to the lackof precise information on regimen and dosage protocols[14]

Thus using a well-established mouse model of T1Dwe investigated the effect of vitamin D supplementationon histological biochemical and hematological parametersand on bronchoalveolar lavage (BAL) and peritoneal lavage(PeL) fluids in male (C57BL6) diabetic and nondiabeticmice The hypothesis is that vitamin D supplementationimproves the hematological parameters and reduces inflam-matory cell migration into the PeL and BAL fluid of diabeticmice

2 Materials and Methods

21 Animals Thirty-one specific pathogen-free maleC57BL6 mice weighing 25 plusmn 2 g at baseline were used Theanimals were maintained at 22∘C under a 12 h light-darkcycle Food and water were provided ad libitum before andduring the experimental period This study was conductedin strict accordance with the principles and guidelines of theNational Council for the Control of Animal Experimentation(CONCEA) and approved by the Ethics Committee onAnimal Use (CEUA) at the School of PharmaceuticalSciences (FCF) University of Sao Paulo Brazil (protocolnumber CEUAFCF389) Surgery was performed underketaminexylazine anesthesia and all efforts were made tominimize animal suffering

22 Induction of Diabetes Mellitus Animals were sepa-rated in four groups control (C) control supplementedwith vitamin D (CV) diabetic (D) and diabetic supple-mented with vitamin D (DV) Briefly diabetes mellituswas induced by intravenous injection of 60mgkg alloxanmonohydrate (ALX) (Sigma Chemical Co St Louis MOUSA) dissolved in physiological saline (09 NaCl) Controlmice were injected with physiological saline only Ten daysafter diabetes induction body weight was measured andperipheral blood (tail vein) glucose level was determinedusing an Accu-Chek Advantage II blood glucose monitor(Roche Diagnostica Sao Paulo SP Brazil) Animals wereconsidered diabetic if glucose level was above 300mgdL[15]

23 Vitamin D Supplementation Animals in the CV andDV groups were supplemented orally with 800 IU of vitaminD (Sanofi Aventis Sao Paulo SP Brazil) for seven days[14] The last dose of vitamin D was administered 24 hbefore the experiment to minimize stress-induced endocrinechanges caused by oral administration of the hormone[16] Body weight and blood glucose were measured onthe first fourth and seventh day of the supplementationperiod

24 Blood Collection Animals were anesthetized by anintraperitoneal injection of 10mgkg xylazine hydrochloride(Ceva Sante Animale Paulınia SP Brazil) and 90mgkgketamine hydrochloride (Ceva Sante Animale) Blood wascollected from anesthetized animals by cardiac punctureSamples of EDTA-anticoagulated blood were used to deter-mine the following hematological parameters red bloodcell (RBC) count white blood cell (WBC) count hemat-ocrit (Htc) and hemoglobin (Hb) All analyses were per-formed using a veterinary hematology analyser ABC Vet(HORIBA UK) Differential cell counts were determinedon stained slides under oil immersion microscopy Based onmorphological criteria 100 cells per sample were countedand classified as either mononuclear or polymorphonuclearA sample aliquot without anticoagulant was centrifuged(10min 3500 rpm) at room temperature Next the serumwasseparated and used for measuring ionic calcium (Ca) phos-phorus (P) albumin alanine transaminase (ALT) aspartateaminotransferase (AST) alkaline phosphatase (ALP) ureaand creatinine by colorimetric assay according to the man-ufacturerrsquos protocol (LabTest Diagnostica Lagoa Santa MGBrazil) Serum 25(OH)D was measured by EUROIMMUN25ndashOHndashVitamin D ELISA kit (Luebeck Germany) Serumsamples were stored at minus80∘C

25 Peritoneal and Bronchoalveolar Lavage The abdomenof all mice was exposed through a ventral midline incisionPeritoneal lavage (PeL)was performedby instillation of 10mL(two 5mL infusions) of phosphate buffered saline (PBS137mM NaCl 27mM KCl 43mM Na2HPO4 and 147mMKH2PO4 pH 74) at room temperature [17] The tracheawas exposed through a midline ventral incision in the neckBronchoalveolar lavage (BAL) was performed by instillationof 5mL (five 1mL infusions) of PBS at room temperaturethrough a 16G times 18810158401015840 BD Angiocath polyethylene tube(BD Franklin Lakes NJ USA) inserted into the tracheaNext PeL and BAL samples were centrifuged (1500 rpm10min 4∘C) supernatants were discarded and the cellswere resuspended in PBS (1mL) The cell suspension wasdiluted 1 2 (v v) with Turkrsquos solution Total cell counts weredetermined using a Neubauer chamber and differential cellcounts were examined on stained slides under oil immersionmicroscopy A total of 100 cells were counted and classifiedas neutrophils lymphocytes or macrophages based on mor-phological criteria

32 Analysis of Vitamin D Supplementation Animals supple-mented with cholecalciferol (CV and DV groups) exhibitedhigher serum 25(OH)2D (ngmL) levels than their respectivecontrols (C andD groups)These results indicate that vitaminD supplementation was successful (Figure 1(a))

Diabetic mice had lower serum Ca (mgdL) levels thannondiabetic animals However vitamin D supplementationrestored serum Ca levels in the DV group (Figure 1(b))

Serum phosphorus (mgdL) levels were significantlyhigher in vitamin D-treated nondiabetic mice compared tonondiabetic controls (Figure 1(c))

33 Temporal Variation of Blood Glucose Levels and BodyWeight Body weight gain and blood glucose levels weremeasured during the supplementation period Body weightwasmeasured in the first and seventh days of the experimentThere was no significant difference in body weight variationbetween vitamin D3-supplemented animals (CV 01 plusmn 03 g119899 = 9 DV minus13 plusmn 10 g 119899 = 7) and their respective controls(C 03 plusmn 03 g 119899 = 9 D minus11 plusmn 09 g 119899 = 6) Bloodglucose was measured on the first fourth and seventhday of the experimental period (Figure 1(j)) There was nosignificant difference in glycemic evolution between vitaminD3-supplemented (CV and DV) groups and controls (Cand D groups) However blood glucose levels remainedsignificantly higher in diabetic mice (D and DV groups) thanin controls (C and CV)

34 Vitamin D3 Supplementation Improved HematologicalParameters Diabetic mice had lower RBC Hb Htc WBCand peripheral blood mononuclear cell counts than controls(Figure 2) Diabetic mice supplemented with vitamin D3had higher RBC Hb Htc WBC and mononuclear cellcounts than diabetic mice In addition diabetic mice sup-plemented with vitamin D3 had higher Hb and hematocritlevels than nondiabetic mice supplemented with vitamin D3(Figure 2)

35 Vitamin D3 Supplementation in the Kidneys and LiverDiabetic mice had significantly higher serum levels of urea(Figure 1(d)) and creatinine than controls (Figure 1(e)) Inaddition diabetic mice had a significant reduction in serumalbumin concentration compared to controls (Figure 1(f))However there were no significant differences in serum levelsofALPAST andALT (Figures 1(g)ndash1(i)) between vitaminD3-treated mice and their respective controls Compared to con-trols diabetic mice exhibited a thickening of the Bowmanrsquoscapsule However vitaminD supplementation did not restorethis renal parameter (Figure 3) No significant differencesin liver (Figure 4) and lung (Figure 5) morphology wereobserved between vitamin D3-supplemented animals (CVand DV) and their respective controls

36 Cell Composition of Bronchoalveolar Lavage and Peritone-al Lavage Fluids The PeL fluid of vitamin D3-supplementedmice had 49-fold more neutrophils than respective controlsbut no significant difference in total cell counts was observedacross groups Total leukocyte counts in the PeL fluid werereduced by 47 in vitamin D3-treated diabetic mice com-paredwith diabeticmice Similarly a 57-fold decrease in totalleukocyte count was observed in the BAL fluid of vitaminD3-treated diabetic mice (Table 1)

4 Discussion

Alloxan (ALX) is an effective diabetes-inducing agent widelyused in experimental animal models ALX administrationproduces hyperglycemia which leads to polyuria and weightloss [18] In our study blood glucose and body weight weremeasured 10 days after ALX administration During theexperimental period diabetic mice exhibited lower bodyweight gain and hyperglycemia than nondiabetic miceBoth metabolic alterations may occur due to increasedlipolysis and oxidative degradation of amino acids thatincrease tissue energy expenditure and body weight loss[19]

Few studies have demonstrated the effects of vitamin D3supplementation on T1D in animal models Neverthelessresults are controversial due to the use of different animalstrains protocols doses periods and routes of supplemen-tation In our study diabetic and nondiabetic mice sup-plemented with 800 IU (40000 IUkg body weightday) ofvitamin D3 had higher serum 25(OH)2D levels than controlsAccording to Takiishi et al (2014) this dose causes nosignificant alterations in serum P or Ca levels in nonobesediabetic (NOD) mice [14]

The role of vitamin D3 in body weight control is con-troversial The presence of 1120572ndashhydroxylase and VDR inadipose tissue cells suggests the involvement of vitamin D inbody weight regulation [20] Weight loss has been associatedwith Ca metabolism which is regulated by Vitamin D3The increase in Ca availability enhances oxidation promotesapoptosis of adipocytes and reduces the absorption of lipidsdue to the formation of insoluble molecules in the intestine[21] However Takiishi et al found no difference in bodyweight variation between vitamin D3-treated NODmice andcontrols [14] Similarly in our study there was no significantdifference in body weight variation between vitamin D3-treatedmice and controls during the supplementation period

The effects of vitamin D3 supplementation on glycemiccontrol in animal models are controversial Relative tocontrols NOD mice treated with high doses of calcitriol

(5 120583gkgalternate days) showed lower insulitis and a reduc-tion in T cell counts [22] However vitamin D supple-mentation had little effect in reverting overt diabetes instreptozotocin-induced diabetic mice [23] In the currentstudy vitamin D supplementation did not reduce bloodglucose levels in diabetic mice compared to controls

Themajor role of vitaminD3 in the body is to regulate theconcentrations of Ca and P [8] Few studies have focused onhow vitamin D and its analogues may affect Ca homeostasisin T1D [24 25] In addition diabetic individuals can exhibitlow serum Ca and P levels due to renal disorders [26] Inthe current study serum concentrations of these ions weremeasured Diabetic mice had lower serum Ca levels thancontrols and vitamin D3 supplementation increased theselevels in the former High 125(OH)2D levels stimulate boneturnover renal excretion and intestinal Ca absorption [7]

However serum P levels in our study were significantlyhigher in vitamin D3-treated nondiabetic mice than controlsThere was no significant difference in P levels betweenvitamin D3-treated and control diabetic mice

Vitamin D is transported by albumin and vitamin D-binding protein in the bloodstream to the liver and kidneyswhere it is activated [7 8] In the current study liver enzymes(ALP ALT and AST) were measured to determine organdysfunction in diabetic and nondiabetic mice The concen-trations of serum ALT AST and ALP were not significantlydifferent between mice supplemented with vitamin D andcontrols Measuring serum urea and creatinine levels is analternative approach to estimate renal function [27] In ourstudy diabetic mice showed low albumin levels and highserum levels of both creatinine and urea and a thickening ofthe Bowmanrsquos capsule compared to nondiabetic mice Theseresults may indicate renal failure [4] However vitamin Dsupplementation did not restore these renal parameters

Alterations in hematological parameters are commonin diabetes patients [28] Hyperglycemia-induced oxidativestress in diabetic conditions leads to functional and mor-phological alterations of the erythrocyte membrane [29]Theincreased nonenzymatic glycosylation of RBC membraneproteins and hyperglycemia could be responsible for thelow Hb levels in these patients [30] Hyperglycemia andoxidation of these proteins increase the production of lipidperoxides that lead to hemolysis of RBC [31] In our studydiabetic mice had lower RBC counts and Hb and Htc levelsthan controls Conversely vitamin D3-treated diabetic miceshowed RBC counts and Htc and Hb levels similar to thoseof nondiabetic mice These findings suggest that vitaminD may affect erythropoiesis Some studies have shown thatVDR is expressed in the bone marrow by specific cell subsetssuch as stromal and accessory cells [32] In addition Aucellaet al reported that patients with chronic kidney diseaseundergoing hemodialysis showed a significant increase in Hb

Increased WBC counts are common in acute andchronic diabetes complications [34] However Matough et alobserved lowerWBC counts in diabetic mice as compared tonondiabetic animals [30] In our study diabetic mice showedlower mononuclear cell and WBC counts than control miceConversely vitamin D3 treatment restored mononuclear cellandWBC counts on diabetic mice to levels similar to those ofnondiabetic mice Interestingly vitamin D3-treated diabeticmice showed a reduction in pulmonary and peritonealleukocyte counts compared to diabetic animals Some studieshave shown that VDR expression on leukocyte subsets [35]could increase leukocytemigration from tissues to peripheralblood

Taken together our results suggest that vitamin D sup-plementation may improve hematological parameters and

reduce cell counts of BAL and PeL fluids during the courseof diabetes

D that interacts with vitamin D receptor (VDR) to performits biological activity [7]

The classic activity of calcitriol is to regulate bonemetabolism by maintaining a balance between calcium (Ca)and phosphorus (P) concentrations [8] Studies have reportedthat vitaminDmay affect the course of T1D by immunomod-ulation [11] Although the mechanism of action is stillunknown serum 125(OH)2D levels appear to modulate thelevel of systemic cytokine production and to increase whiteblood cell (WBC) count [12 13]

Although vitamin D supplementation is an importantaid in clinical practice few studies have demonstrated theeffects of vitamin D supplementation on the course of T1Din humans and animals In addition vitamin D supple-mentation studies are often contradictory due to the lackof precise information on regimen and dosage protocols[14]

Thus using a well-established mouse model of T1Dwe investigated the effect of vitamin D supplementationon histological biochemical and hematological parametersand on bronchoalveolar lavage (BAL) and peritoneal lavage(PeL) fluids in male (C57BL6) diabetic and nondiabeticmice The hypothesis is that vitamin D supplementationimproves the hematological parameters and reduces inflam-matory cell migration into the PeL and BAL fluid of diabeticmice

2 Materials and Methods

21 Animals Thirty-one specific pathogen-free maleC57BL6 mice weighing 25 plusmn 2 g at baseline were used Theanimals were maintained at 22∘C under a 12 h light-darkcycle Food and water were provided ad libitum before andduring the experimental period This study was conductedin strict accordance with the principles and guidelines of theNational Council for the Control of Animal Experimentation(CONCEA) and approved by the Ethics Committee onAnimal Use (CEUA) at the School of PharmaceuticalSciences (FCF) University of Sao Paulo Brazil (protocolnumber CEUAFCF389) Surgery was performed underketaminexylazine anesthesia and all efforts were made tominimize animal suffering

22 Induction of Diabetes Mellitus Animals were sepa-rated in four groups control (C) control supplementedwith vitamin D (CV) diabetic (D) and diabetic supple-mented with vitamin D (DV) Briefly diabetes mellituswas induced by intravenous injection of 60mgkg alloxanmonohydrate (ALX) (Sigma Chemical Co St Louis MOUSA) dissolved in physiological saline (09 NaCl) Controlmice were injected with physiological saline only Ten daysafter diabetes induction body weight was measured andperipheral blood (tail vein) glucose level was determinedusing an Accu-Chek Advantage II blood glucose monitor(Roche Diagnostica Sao Paulo SP Brazil) Animals wereconsidered diabetic if glucose level was above 300mgdL[15]

23 Vitamin D Supplementation Animals in the CV andDV groups were supplemented orally with 800 IU of vitaminD (Sanofi Aventis Sao Paulo SP Brazil) for seven days[14] The last dose of vitamin D was administered 24 hbefore the experiment to minimize stress-induced endocrinechanges caused by oral administration of the hormone[16] Body weight and blood glucose were measured onthe first fourth and seventh day of the supplementationperiod

24 Blood Collection Animals were anesthetized by anintraperitoneal injection of 10mgkg xylazine hydrochloride(Ceva Sante Animale Paulınia SP Brazil) and 90mgkgketamine hydrochloride (Ceva Sante Animale) Blood wascollected from anesthetized animals by cardiac punctureSamples of EDTA-anticoagulated blood were used to deter-mine the following hematological parameters red bloodcell (RBC) count white blood cell (WBC) count hemat-ocrit (Htc) and hemoglobin (Hb) All analyses were per-formed using a veterinary hematology analyser ABC Vet(HORIBA UK) Differential cell counts were determinedon stained slides under oil immersion microscopy Based onmorphological criteria 100 cells per sample were countedand classified as either mononuclear or polymorphonuclearA sample aliquot without anticoagulant was centrifuged(10min 3500 rpm) at room temperature Next the serumwasseparated and used for measuring ionic calcium (Ca) phos-phorus (P) albumin alanine transaminase (ALT) aspartateaminotransferase (AST) alkaline phosphatase (ALP) ureaand creatinine by colorimetric assay according to the man-ufacturerrsquos protocol (LabTest Diagnostica Lagoa Santa MGBrazil) Serum 25(OH)D was measured by EUROIMMUN25ndashOHndashVitamin D ELISA kit (Luebeck Germany) Serumsamples were stored at minus80∘C

25 Peritoneal and Bronchoalveolar Lavage The abdomenof all mice was exposed through a ventral midline incisionPeritoneal lavage (PeL)was performedby instillation of 10mL(two 5mL infusions) of phosphate buffered saline (PBS137mM NaCl 27mM KCl 43mM Na2HPO4 and 147mMKH2PO4 pH 74) at room temperature [17] The tracheawas exposed through a midline ventral incision in the neckBronchoalveolar lavage (BAL) was performed by instillationof 5mL (five 1mL infusions) of PBS at room temperaturethrough a 16G times 18810158401015840 BD Angiocath polyethylene tube(BD Franklin Lakes NJ USA) inserted into the tracheaNext PeL and BAL samples were centrifuged (1500 rpm10min 4∘C) supernatants were discarded and the cellswere resuspended in PBS (1mL) The cell suspension wasdiluted 1 2 (v v) with Turkrsquos solution Total cell counts weredetermined using a Neubauer chamber and differential cellcounts were examined on stained slides under oil immersionmicroscopy A total of 100 cells were counted and classifiedas neutrophils lymphocytes or macrophages based on mor-phological criteria

32 Analysis of Vitamin D Supplementation Animals supple-mented with cholecalciferol (CV and DV groups) exhibitedhigher serum 25(OH)2D (ngmL) levels than their respectivecontrols (C andD groups)These results indicate that vitaminD supplementation was successful (Figure 1(a))

Diabetic mice had lower serum Ca (mgdL) levels thannondiabetic animals However vitamin D supplementationrestored serum Ca levels in the DV group (Figure 1(b))

Serum phosphorus (mgdL) levels were significantlyhigher in vitamin D-treated nondiabetic mice compared tonondiabetic controls (Figure 1(c))

33 Temporal Variation of Blood Glucose Levels and BodyWeight Body weight gain and blood glucose levels weremeasured during the supplementation period Body weightwasmeasured in the first and seventh days of the experimentThere was no significant difference in body weight variationbetween vitamin D3-supplemented animals (CV 01 plusmn 03 g119899 = 9 DV minus13 plusmn 10 g 119899 = 7) and their respective controls(C 03 plusmn 03 g 119899 = 9 D minus11 plusmn 09 g 119899 = 6) Bloodglucose was measured on the first fourth and seventhday of the experimental period (Figure 1(j)) There was nosignificant difference in glycemic evolution between vitaminD3-supplemented (CV and DV) groups and controls (Cand D groups) However blood glucose levels remainedsignificantly higher in diabetic mice (D and DV groups) thanin controls (C and CV)

34 Vitamin D3 Supplementation Improved HematologicalParameters Diabetic mice had lower RBC Hb Htc WBCand peripheral blood mononuclear cell counts than controls(Figure 2) Diabetic mice supplemented with vitamin D3had higher RBC Hb Htc WBC and mononuclear cellcounts than diabetic mice In addition diabetic mice sup-plemented with vitamin D3 had higher Hb and hematocritlevels than nondiabetic mice supplemented with vitamin D3(Figure 2)

35 Vitamin D3 Supplementation in the Kidneys and LiverDiabetic mice had significantly higher serum levels of urea(Figure 1(d)) and creatinine than controls (Figure 1(e)) Inaddition diabetic mice had a significant reduction in serumalbumin concentration compared to controls (Figure 1(f))However there were no significant differences in serum levelsofALPAST andALT (Figures 1(g)ndash1(i)) between vitaminD3-treated mice and their respective controls Compared to con-trols diabetic mice exhibited a thickening of the Bowmanrsquoscapsule However vitaminD supplementation did not restorethis renal parameter (Figure 3) No significant differencesin liver (Figure 4) and lung (Figure 5) morphology wereobserved between vitamin D3-supplemented animals (CVand DV) and their respective controls

36 Cell Composition of Bronchoalveolar Lavage and Peritone-al Lavage Fluids The PeL fluid of vitamin D3-supplementedmice had 49-fold more neutrophils than respective controlsbut no significant difference in total cell counts was observedacross groups Total leukocyte counts in the PeL fluid werereduced by 47 in vitamin D3-treated diabetic mice com-paredwith diabeticmice Similarly a 57-fold decrease in totalleukocyte count was observed in the BAL fluid of vitaminD3-treated diabetic mice (Table 1)

4 Discussion

Alloxan (ALX) is an effective diabetes-inducing agent widelyused in experimental animal models ALX administrationproduces hyperglycemia which leads to polyuria and weightloss [18] In our study blood glucose and body weight weremeasured 10 days after ALX administration During theexperimental period diabetic mice exhibited lower bodyweight gain and hyperglycemia than nondiabetic miceBoth metabolic alterations may occur due to increasedlipolysis and oxidative degradation of amino acids thatincrease tissue energy expenditure and body weight loss[19]

Few studies have demonstrated the effects of vitamin D3supplementation on T1D in animal models Neverthelessresults are controversial due to the use of different animalstrains protocols doses periods and routes of supplemen-tation In our study diabetic and nondiabetic mice sup-plemented with 800 IU (40000 IUkg body weightday) ofvitamin D3 had higher serum 25(OH)2D levels than controlsAccording to Takiishi et al (2014) this dose causes nosignificant alterations in serum P or Ca levels in nonobesediabetic (NOD) mice [14]

The role of vitamin D3 in body weight control is con-troversial The presence of 1120572ndashhydroxylase and VDR inadipose tissue cells suggests the involvement of vitamin D inbody weight regulation [20] Weight loss has been associatedwith Ca metabolism which is regulated by Vitamin D3The increase in Ca availability enhances oxidation promotesapoptosis of adipocytes and reduces the absorption of lipidsdue to the formation of insoluble molecules in the intestine[21] However Takiishi et al found no difference in bodyweight variation between vitamin D3-treated NODmice andcontrols [14] Similarly in our study there was no significantdifference in body weight variation between vitamin D3-treatedmice and controls during the supplementation period

The effects of vitamin D3 supplementation on glycemiccontrol in animal models are controversial Relative tocontrols NOD mice treated with high doses of calcitriol

(5 120583gkgalternate days) showed lower insulitis and a reduc-tion in T cell counts [22] However vitamin D supple-mentation had little effect in reverting overt diabetes instreptozotocin-induced diabetic mice [23] In the currentstudy vitamin D supplementation did not reduce bloodglucose levels in diabetic mice compared to controls

Themajor role of vitaminD3 in the body is to regulate theconcentrations of Ca and P [8] Few studies have focused onhow vitamin D and its analogues may affect Ca homeostasisin T1D [24 25] In addition diabetic individuals can exhibitlow serum Ca and P levels due to renal disorders [26] Inthe current study serum concentrations of these ions weremeasured Diabetic mice had lower serum Ca levels thancontrols and vitamin D3 supplementation increased theselevels in the former High 125(OH)2D levels stimulate boneturnover renal excretion and intestinal Ca absorption [7]

However serum P levels in our study were significantlyhigher in vitamin D3-treated nondiabetic mice than controlsThere was no significant difference in P levels betweenvitamin D3-treated and control diabetic mice

Vitamin D is transported by albumin and vitamin D-binding protein in the bloodstream to the liver and kidneyswhere it is activated [7 8] In the current study liver enzymes(ALP ALT and AST) were measured to determine organdysfunction in diabetic and nondiabetic mice The concen-trations of serum ALT AST and ALP were not significantlydifferent between mice supplemented with vitamin D andcontrols Measuring serum urea and creatinine levels is analternative approach to estimate renal function [27] In ourstudy diabetic mice showed low albumin levels and highserum levels of both creatinine and urea and a thickening ofthe Bowmanrsquos capsule compared to nondiabetic mice Theseresults may indicate renal failure [4] However vitamin Dsupplementation did not restore these renal parameters

Alterations in hematological parameters are commonin diabetes patients [28] Hyperglycemia-induced oxidativestress in diabetic conditions leads to functional and mor-phological alterations of the erythrocyte membrane [29]Theincreased nonenzymatic glycosylation of RBC membraneproteins and hyperglycemia could be responsible for thelow Hb levels in these patients [30] Hyperglycemia andoxidation of these proteins increase the production of lipidperoxides that lead to hemolysis of RBC [31] In our studydiabetic mice had lower RBC counts and Hb and Htc levelsthan controls Conversely vitamin D3-treated diabetic miceshowed RBC counts and Htc and Hb levels similar to thoseof nondiabetic mice These findings suggest that vitaminD may affect erythropoiesis Some studies have shown thatVDR is expressed in the bone marrow by specific cell subsetssuch as stromal and accessory cells [32] In addition Aucellaet al reported that patients with chronic kidney diseaseundergoing hemodialysis showed a significant increase in Hb

Increased WBC counts are common in acute andchronic diabetes complications [34] However Matough et alobserved lowerWBC counts in diabetic mice as compared tonondiabetic animals [30] In our study diabetic mice showedlower mononuclear cell and WBC counts than control miceConversely vitamin D3 treatment restored mononuclear cellandWBC counts on diabetic mice to levels similar to those ofnondiabetic mice Interestingly vitamin D3-treated diabeticmice showed a reduction in pulmonary and peritonealleukocyte counts compared to diabetic animals Some studieshave shown that VDR expression on leukocyte subsets [35]could increase leukocytemigration from tissues to peripheralblood

Taken together our results suggest that vitamin D sup-plementation may improve hematological parameters and

reduce cell counts of BAL and PeL fluids during the courseof diabetes

32 Analysis of Vitamin D Supplementation Animals supple-mented with cholecalciferol (CV and DV groups) exhibitedhigher serum 25(OH)2D (ngmL) levels than their respectivecontrols (C andD groups)These results indicate that vitaminD supplementation was successful (Figure 1(a))

Diabetic mice had lower serum Ca (mgdL) levels thannondiabetic animals However vitamin D supplementationrestored serum Ca levels in the DV group (Figure 1(b))

Serum phosphorus (mgdL) levels were significantlyhigher in vitamin D-treated nondiabetic mice compared tonondiabetic controls (Figure 1(c))

33 Temporal Variation of Blood Glucose Levels and BodyWeight Body weight gain and blood glucose levels weremeasured during the supplementation period Body weightwasmeasured in the first and seventh days of the experimentThere was no significant difference in body weight variationbetween vitamin D3-supplemented animals (CV 01 plusmn 03 g119899 = 9 DV minus13 plusmn 10 g 119899 = 7) and their respective controls(C 03 plusmn 03 g 119899 = 9 D minus11 plusmn 09 g 119899 = 6) Bloodglucose was measured on the first fourth and seventhday of the experimental period (Figure 1(j)) There was nosignificant difference in glycemic evolution between vitaminD3-supplemented (CV and DV) groups and controls (Cand D groups) However blood glucose levels remainedsignificantly higher in diabetic mice (D and DV groups) thanin controls (C and CV)

34 Vitamin D3 Supplementation Improved HematologicalParameters Diabetic mice had lower RBC Hb Htc WBCand peripheral blood mononuclear cell counts than controls(Figure 2) Diabetic mice supplemented with vitamin D3had higher RBC Hb Htc WBC and mononuclear cellcounts than diabetic mice In addition diabetic mice sup-plemented with vitamin D3 had higher Hb and hematocritlevels than nondiabetic mice supplemented with vitamin D3(Figure 2)

35 Vitamin D3 Supplementation in the Kidneys and LiverDiabetic mice had significantly higher serum levels of urea(Figure 1(d)) and creatinine than controls (Figure 1(e)) Inaddition diabetic mice had a significant reduction in serumalbumin concentration compared to controls (Figure 1(f))However there were no significant differences in serum levelsofALPAST andALT (Figures 1(g)ndash1(i)) between vitaminD3-treated mice and their respective controls Compared to con-trols diabetic mice exhibited a thickening of the Bowmanrsquoscapsule However vitaminD supplementation did not restorethis renal parameter (Figure 3) No significant differencesin liver (Figure 4) and lung (Figure 5) morphology wereobserved between vitamin D3-supplemented animals (CVand DV) and their respective controls

36 Cell Composition of Bronchoalveolar Lavage and Peritone-al Lavage Fluids The PeL fluid of vitamin D3-supplementedmice had 49-fold more neutrophils than respective controlsbut no significant difference in total cell counts was observedacross groups Total leukocyte counts in the PeL fluid werereduced by 47 in vitamin D3-treated diabetic mice com-paredwith diabeticmice Similarly a 57-fold decrease in totalleukocyte count was observed in the BAL fluid of vitaminD3-treated diabetic mice (Table 1)

4 Discussion

Alloxan (ALX) is an effective diabetes-inducing agent widelyused in experimental animal models ALX administrationproduces hyperglycemia which leads to polyuria and weightloss [18] In our study blood glucose and body weight weremeasured 10 days after ALX administration During theexperimental period diabetic mice exhibited lower bodyweight gain and hyperglycemia than nondiabetic miceBoth metabolic alterations may occur due to increasedlipolysis and oxidative degradation of amino acids thatincrease tissue energy expenditure and body weight loss[19]

Few studies have demonstrated the effects of vitamin D3supplementation on T1D in animal models Neverthelessresults are controversial due to the use of different animalstrains protocols doses periods and routes of supplemen-tation In our study diabetic and nondiabetic mice sup-plemented with 800 IU (40000 IUkg body weightday) ofvitamin D3 had higher serum 25(OH)2D levels than controlsAccording to Takiishi et al (2014) this dose causes nosignificant alterations in serum P or Ca levels in nonobesediabetic (NOD) mice [14]

The role of vitamin D3 in body weight control is con-troversial The presence of 1120572ndashhydroxylase and VDR inadipose tissue cells suggests the involvement of vitamin D inbody weight regulation [20] Weight loss has been associatedwith Ca metabolism which is regulated by Vitamin D3The increase in Ca availability enhances oxidation promotesapoptosis of adipocytes and reduces the absorption of lipidsdue to the formation of insoluble molecules in the intestine[21] However Takiishi et al found no difference in bodyweight variation between vitamin D3-treated NODmice andcontrols [14] Similarly in our study there was no significantdifference in body weight variation between vitamin D3-treatedmice and controls during the supplementation period

The effects of vitamin D3 supplementation on glycemiccontrol in animal models are controversial Relative tocontrols NOD mice treated with high doses of calcitriol

(5 120583gkgalternate days) showed lower insulitis and a reduc-tion in T cell counts [22] However vitamin D supple-mentation had little effect in reverting overt diabetes instreptozotocin-induced diabetic mice [23] In the currentstudy vitamin D supplementation did not reduce bloodglucose levels in diabetic mice compared to controls

Themajor role of vitaminD3 in the body is to regulate theconcentrations of Ca and P [8] Few studies have focused onhow vitamin D and its analogues may affect Ca homeostasisin T1D [24 25] In addition diabetic individuals can exhibitlow serum Ca and P levels due to renal disorders [26] Inthe current study serum concentrations of these ions weremeasured Diabetic mice had lower serum Ca levels thancontrols and vitamin D3 supplementation increased theselevels in the former High 125(OH)2D levels stimulate boneturnover renal excretion and intestinal Ca absorption [7]

However serum P levels in our study were significantlyhigher in vitamin D3-treated nondiabetic mice than controlsThere was no significant difference in P levels betweenvitamin D3-treated and control diabetic mice

Vitamin D is transported by albumin and vitamin D-binding protein in the bloodstream to the liver and kidneyswhere it is activated [7 8] In the current study liver enzymes(ALP ALT and AST) were measured to determine organdysfunction in diabetic and nondiabetic mice The concen-trations of serum ALT AST and ALP were not significantlydifferent between mice supplemented with vitamin D andcontrols Measuring serum urea and creatinine levels is analternative approach to estimate renal function [27] In ourstudy diabetic mice showed low albumin levels and highserum levels of both creatinine and urea and a thickening ofthe Bowmanrsquos capsule compared to nondiabetic mice Theseresults may indicate renal failure [4] However vitamin Dsupplementation did not restore these renal parameters

Alterations in hematological parameters are commonin diabetes patients [28] Hyperglycemia-induced oxidativestress in diabetic conditions leads to functional and mor-phological alterations of the erythrocyte membrane [29]Theincreased nonenzymatic glycosylation of RBC membraneproteins and hyperglycemia could be responsible for thelow Hb levels in these patients [30] Hyperglycemia andoxidation of these proteins increase the production of lipidperoxides that lead to hemolysis of RBC [31] In our studydiabetic mice had lower RBC counts and Hb and Htc levelsthan controls Conversely vitamin D3-treated diabetic miceshowed RBC counts and Htc and Hb levels similar to thoseof nondiabetic mice These findings suggest that vitaminD may affect erythropoiesis Some studies have shown thatVDR is expressed in the bone marrow by specific cell subsetssuch as stromal and accessory cells [32] In addition Aucellaet al reported that patients with chronic kidney diseaseundergoing hemodialysis showed a significant increase in Hb

Increased WBC counts are common in acute andchronic diabetes complications [34] However Matough et alobserved lowerWBC counts in diabetic mice as compared tonondiabetic animals [30] In our study diabetic mice showedlower mononuclear cell and WBC counts than control miceConversely vitamin D3 treatment restored mononuclear cellandWBC counts on diabetic mice to levels similar to those ofnondiabetic mice Interestingly vitamin D3-treated diabeticmice showed a reduction in pulmonary and peritonealleukocyte counts compared to diabetic animals Some studieshave shown that VDR expression on leukocyte subsets [35]could increase leukocytemigration from tissues to peripheralblood

Taken together our results suggest that vitamin D sup-plementation may improve hematological parameters and

reduce cell counts of BAL and PeL fluids during the courseof diabetes

The role of vitamin D3 in body weight control is con-troversial The presence of 1120572ndashhydroxylase and VDR inadipose tissue cells suggests the involvement of vitamin D inbody weight regulation [20] Weight loss has been associatedwith Ca metabolism which is regulated by Vitamin D3The increase in Ca availability enhances oxidation promotesapoptosis of adipocytes and reduces the absorption of lipidsdue to the formation of insoluble molecules in the intestine[21] However Takiishi et al found no difference in bodyweight variation between vitamin D3-treated NODmice andcontrols [14] Similarly in our study there was no significantdifference in body weight variation between vitamin D3-treatedmice and controls during the supplementation period

The effects of vitamin D3 supplementation on glycemiccontrol in animal models are controversial Relative tocontrols NOD mice treated with high doses of calcitriol

(5 120583gkgalternate days) showed lower insulitis and a reduc-tion in T cell counts [22] However vitamin D supple-mentation had little effect in reverting overt diabetes instreptozotocin-induced diabetic mice [23] In the currentstudy vitamin D supplementation did not reduce bloodglucose levels in diabetic mice compared to controls

Themajor role of vitaminD3 in the body is to regulate theconcentrations of Ca and P [8] Few studies have focused onhow vitamin D and its analogues may affect Ca homeostasisin T1D [24 25] In addition diabetic individuals can exhibitlow serum Ca and P levels due to renal disorders [26] Inthe current study serum concentrations of these ions weremeasured Diabetic mice had lower serum Ca levels thancontrols and vitamin D3 supplementation increased theselevels in the former High 125(OH)2D levels stimulate boneturnover renal excretion and intestinal Ca absorption [7]

However serum P levels in our study were significantlyhigher in vitamin D3-treated nondiabetic mice than controlsThere was no significant difference in P levels betweenvitamin D3-treated and control diabetic mice

Vitamin D is transported by albumin and vitamin D-binding protein in the bloodstream to the liver and kidneyswhere it is activated [7 8] In the current study liver enzymes(ALP ALT and AST) were measured to determine organdysfunction in diabetic and nondiabetic mice The concen-trations of serum ALT AST and ALP were not significantlydifferent between mice supplemented with vitamin D andcontrols Measuring serum urea and creatinine levels is analternative approach to estimate renal function [27] In ourstudy diabetic mice showed low albumin levels and highserum levels of both creatinine and urea and a thickening ofthe Bowmanrsquos capsule compared to nondiabetic mice Theseresults may indicate renal failure [4] However vitamin Dsupplementation did not restore these renal parameters

Alterations in hematological parameters are commonin diabetes patients [28] Hyperglycemia-induced oxidativestress in diabetic conditions leads to functional and mor-phological alterations of the erythrocyte membrane [29]Theincreased nonenzymatic glycosylation of RBC membraneproteins and hyperglycemia could be responsible for thelow Hb levels in these patients [30] Hyperglycemia andoxidation of these proteins increase the production of lipidperoxides that lead to hemolysis of RBC [31] In our studydiabetic mice had lower RBC counts and Hb and Htc levelsthan controls Conversely vitamin D3-treated diabetic miceshowed RBC counts and Htc and Hb levels similar to thoseof nondiabetic mice These findings suggest that vitaminD may affect erythropoiesis Some studies have shown thatVDR is expressed in the bone marrow by specific cell subsetssuch as stromal and accessory cells [32] In addition Aucellaet al reported that patients with chronic kidney diseaseundergoing hemodialysis showed a significant increase in Hb

concentration and Htc level after four months of treatmentwith vitamin D [33]

Increased WBC counts are common in acute andchronic diabetes complications [34] However Matough et alobserved lowerWBC counts in diabetic mice as compared tonondiabetic animals [30] In our study diabetic mice showedlower mononuclear cell and WBC counts than control miceConversely vitamin D3 treatment restored mononuclear cellandWBC counts on diabetic mice to levels similar to those ofnondiabetic mice Interestingly vitamin D3-treated diabeticmice showed a reduction in pulmonary and peritonealleukocyte counts compared to diabetic animals Some studieshave shown that VDR expression on leukocyte subsets [35]could increase leukocytemigration from tissues to peripheralblood

Taken together our results suggest that vitamin D sup-plementation may improve hematological parameters and

reduce cell counts of BAL and PeL fluids during the courseof diabetes

The role of vitamin D3 in body weight control is con-troversial The presence of 1120572ndashhydroxylase and VDR inadipose tissue cells suggests the involvement of vitamin D inbody weight regulation [20] Weight loss has been associatedwith Ca metabolism which is regulated by Vitamin D3The increase in Ca availability enhances oxidation promotesapoptosis of adipocytes and reduces the absorption of lipidsdue to the formation of insoluble molecules in the intestine[21] However Takiishi et al found no difference in bodyweight variation between vitamin D3-treated NODmice andcontrols [14] Similarly in our study there was no significantdifference in body weight variation between vitamin D3-treatedmice and controls during the supplementation period

The effects of vitamin D3 supplementation on glycemiccontrol in animal models are controversial Relative tocontrols NOD mice treated with high doses of calcitriol

(5 120583gkgalternate days) showed lower insulitis and a reduc-tion in T cell counts [22] However vitamin D supple-mentation had little effect in reverting overt diabetes instreptozotocin-induced diabetic mice [23] In the currentstudy vitamin D supplementation did not reduce bloodglucose levels in diabetic mice compared to controls

Themajor role of vitaminD3 in the body is to regulate theconcentrations of Ca and P [8] Few studies have focused onhow vitamin D and its analogues may affect Ca homeostasisin T1D [24 25] In addition diabetic individuals can exhibitlow serum Ca and P levels due to renal disorders [26] Inthe current study serum concentrations of these ions weremeasured Diabetic mice had lower serum Ca levels thancontrols and vitamin D3 supplementation increased theselevels in the former High 125(OH)2D levels stimulate boneturnover renal excretion and intestinal Ca absorption [7]

However serum P levels in our study were significantlyhigher in vitamin D3-treated nondiabetic mice than controlsThere was no significant difference in P levels betweenvitamin D3-treated and control diabetic mice

Vitamin D is transported by albumin and vitamin D-binding protein in the bloodstream to the liver and kidneyswhere it is activated [7 8] In the current study liver enzymes(ALP ALT and AST) were measured to determine organdysfunction in diabetic and nondiabetic mice The concen-trations of serum ALT AST and ALP were not significantlydifferent between mice supplemented with vitamin D andcontrols Measuring serum urea and creatinine levels is analternative approach to estimate renal function [27] In ourstudy diabetic mice showed low albumin levels and highserum levels of both creatinine and urea and a thickening ofthe Bowmanrsquos capsule compared to nondiabetic mice Theseresults may indicate renal failure [4] However vitamin Dsupplementation did not restore these renal parameters

Alterations in hematological parameters are commonin diabetes patients [28] Hyperglycemia-induced oxidativestress in diabetic conditions leads to functional and mor-phological alterations of the erythrocyte membrane [29]Theincreased nonenzymatic glycosylation of RBC membraneproteins and hyperglycemia could be responsible for thelow Hb levels in these patients [30] Hyperglycemia andoxidation of these proteins increase the production of lipidperoxides that lead to hemolysis of RBC [31] In our studydiabetic mice had lower RBC counts and Hb and Htc levelsthan controls Conversely vitamin D3-treated diabetic miceshowed RBC counts and Htc and Hb levels similar to thoseof nondiabetic mice These findings suggest that vitaminD may affect erythropoiesis Some studies have shown thatVDR is expressed in the bone marrow by specific cell subsetssuch as stromal and accessory cells [32] In addition Aucellaet al reported that patients with chronic kidney diseaseundergoing hemodialysis showed a significant increase in Hb

Increased WBC counts are common in acute andchronic diabetes complications [34] However Matough et alobserved lowerWBC counts in diabetic mice as compared tonondiabetic animals [30] In our study diabetic mice showedlower mononuclear cell and WBC counts than control miceConversely vitamin D3 treatment restored mononuclear cellandWBC counts on diabetic mice to levels similar to those ofnondiabetic mice Interestingly vitamin D3-treated diabeticmice showed a reduction in pulmonary and peritonealleukocyte counts compared to diabetic animals Some studieshave shown that VDR expression on leukocyte subsets [35]could increase leukocytemigration from tissues to peripheralblood

Taken together our results suggest that vitamin D sup-plementation may improve hematological parameters and

reduce cell counts of BAL and PeL fluids during the courseof diabetes

However serum P levels in our study were significantlyhigher in vitamin D3-treated nondiabetic mice than controlsThere was no significant difference in P levels betweenvitamin D3-treated and control diabetic mice

Vitamin D is transported by albumin and vitamin D-binding protein in the bloodstream to the liver and kidneyswhere it is activated [7 8] In the current study liver enzymes(ALP ALT and AST) were measured to determine organdysfunction in diabetic and nondiabetic mice The concen-trations of serum ALT AST and ALP were not significantlydifferent between mice supplemented with vitamin D andcontrols Measuring serum urea and creatinine levels is analternative approach to estimate renal function [27] In ourstudy diabetic mice showed low albumin levels and highserum levels of both creatinine and urea and a thickening ofthe Bowmanrsquos capsule compared to nondiabetic mice Theseresults may indicate renal failure [4] However vitamin Dsupplementation did not restore these renal parameters

Alterations in hematological parameters are commonin diabetes patients [28] Hyperglycemia-induced oxidativestress in diabetic conditions leads to functional and mor-phological alterations of the erythrocyte membrane [29]Theincreased nonenzymatic glycosylation of RBC membraneproteins and hyperglycemia could be responsible for thelow Hb levels in these patients [30] Hyperglycemia andoxidation of these proteins increase the production of lipidperoxides that lead to hemolysis of RBC [31] In our studydiabetic mice had lower RBC counts and Hb and Htc levelsthan controls Conversely vitamin D3-treated diabetic miceshowed RBC counts and Htc and Hb levels similar to thoseof nondiabetic mice These findings suggest that vitaminD may affect erythropoiesis Some studies have shown thatVDR is expressed in the bone marrow by specific cell subsetssuch as stromal and accessory cells [32] In addition Aucellaet al reported that patients with chronic kidney diseaseundergoing hemodialysis showed a significant increase in Hb

Increased WBC counts are common in acute andchronic diabetes complications [34] However Matough et alobserved lowerWBC counts in diabetic mice as compared tonondiabetic animals [30] In our study diabetic mice showedlower mononuclear cell and WBC counts than control miceConversely vitamin D3 treatment restored mononuclear cellandWBC counts on diabetic mice to levels similar to those ofnondiabetic mice Interestingly vitamin D3-treated diabeticmice showed a reduction in pulmonary and peritonealleukocyte counts compared to diabetic animals Some studieshave shown that VDR expression on leukocyte subsets [35]could increase leukocytemigration from tissues to peripheralblood

Taken together our results suggest that vitamin D sup-plementation may improve hematological parameters and

reduce cell counts of BAL and PeL fluids during the courseof diabetes
