The purpose of this study was to explore possible protective effects of vitamin D3 on serum glucose
concentration, body weight and histopathology of pancreas and liver. Animals were divided into 3 groups: Control
group (n=6), streptozotocin (STZ) group (n=6) and streptozotocin + vitamin D3 (STZ+D3) group (n=6). Rats in the
STZ+D3 group starting from the 7th day of experiment were given vitamin D3 for 14 days. Glucose levels and body
weight were measured on the 1, 7, 14 and 21st day of experiment. Qualitative histological analysis of pancreas and liver
was done using the light microscope with a digital camera. Differences between the groups were tested by one-way
analysis of variance (ANOVA) followed by Dunnett's posttest. Differences in repeated measures were tested using
paired t-test. On day 14 and 21, blood glucose level in STZ+D3 group was significantly higher compared to the control
group of animals but significantly lower than the glucose level registered in STZ group of rats. On day 14 and day 21,
body weight in STZ rats was significantly lower compared to weight in STZ+D3 and control groups of rats.
Morphological changes, such as shrinkage of islets, vacuolation of both endocrine and exocrine cells, were observed in
pancreas of STZ group of animals but were nearly absent in STZ+D3 rats. Similarly, STZ+D3 group of rats showed
preserved liver histoarchitecture. Obtained results suggest that vitamin D3 treatment reduces hyperglycemia, exerts
beneficial effects on body weight and alleviates histopathological changes in pancreas and liver in STZ-induced diabetic
rats.
