This study was designed to investigate the anti-diabetic effects of selenium nano-particles (SeNPs) at dose of 2 mg/kg body weight in streptozotocin (STZ) induced diabetes in a rat model at dose 50 mg/kg body weight. Rats were administered SeNPs orally in normal and experimentally induced diabetic rats for 35 days and glibenclamide (Glib) at the dose rate of 20 mg/kg, which was used as a reference drug. Blood samples and pancreatic tissue were collected at the end of experiment. Administration of SeNPs significantly decreased blood glucose levels and enhanced serum insulin concentration, the result showed also decrease in liver function enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST).All groups showed non-significant changes in serum creatinine levels, decrease in the cardiac function enzymes creatine kinase-MB (CK-MB). Cholesterol, triglyceride, and lowdensity lipoprotein (LDL) levels were significantly decreased and high-density lipoprotein (HDL) was significantly increased. Histological study revealed that SeNPs were able to prevent atrophy of island of Langerhans cells compared to diabetic group. However, Glib injection also exhibited a significant improvement in diabetic animals after 35 days of treatment. This study suggests that SeNPs capped with chitosan can be used as an antidiabetic showing synergistic effect in STZ-induced diabetic rats,.
