The effects of cyclosporin A (CsA) on rat pancreatic islet \beta and D cells and plasma glucose levels at doses of 50 mg/kg body weight applied for 20 days were investigated. Fifteen Swiss Albino rats were used as the study group and 5 were the control group. Rat pancreatic islet \beta and D cells were stained immunocytochemically by anti-insulin and anti-somatostation antibodies. \beta and D cells from 15 different islets were evaluated qualitatively and quantitatively. Plasma glucose changes were also compared between the study and the control group. The pancreas morphology was found to be normal in both groups by light microscopy. The difference between the numbers of \beta and D cells of pancreatic islets among the groups was not statistically significant. The staining intensity of islet \beta cell cytoplasms was lighter in the CsA administered rats. Plasma glucose levels of CsA-exposed rats increased significantly compared with the control group (p
