title: Effect of chronic treatment with Bis(maltolato)oxovanadium (IV) in rat model of non-insulin-dependent-diabetes.
abstract: Effect of chronic treatment with Bis(maltolato)oxovanadium (IV) (BMOV) was studied in streptozotocin (STZ)-induced neonatal non-insulin-dependent-diabetic (NIDDM) rats. Intraperitoneal injection of STZ (90 mg kg(-1)) in Wistar rat pups (day 2 old) produced mild hyperglycemia, impaired glucose tolerance and insulin resistance at the age of 3 months. Treatment with BMOV (0.23 mM kg(-1)) in drinking water for 6 weeks produced a significant decrease in elevated serum glucose levels without any significant change in serum insulin levels in diabetic rats. BMOV treatment significantly decreased integrated area under the glucose curve without any significant change in integrated area under the insulin curve indicating improved glucose tolerance. Treatment also significantly increased K(ITT) value of diabetic rats indicating increased insulin sensitivity. BMOV treatment significantly reduced hypercholesterolemia in diabetic rats. Treatment also significantly decreased serum triglyceride levels in both diabetic and non-diabetic rats. The data suggest that chronic BMOV treatment improves glucose and lipid homeostasis. These effects appear to be due to the insulin sensitizing action of vanadium.
