Abstract

Objectives: The present study was conducted to evaluate the effect of a standardized hydroalcoholic root extract of Sala¬cia oblonga (SOE) on the Random Blood Glucose (RBG) levels, serum insulin, glycated haemoglobin (HbA1c) and the serum lipid profile in long standing, experimentally induced Diabetes Mellitus (DM) with glibenclamide (Glb) as the standard. Materials and Methods: Streptozotocin (STZ) induced, dia-betic, Wistar rats of either sex were treated with two oral doses of SOE, 100 and 50mg/kg body wt /day, for a period of 16 weeks. The RBG was estimated at day-1 and at the end of the 16 weeks by using a glucometer. The fasting serum insulin was determined by an ELISA technique. The plasma HbA1c was evaluated by a Turbidimetric Inhibition Immunoassay (TINIA) and the lipid profile was estimated enzymatically. Results and Analysis: A 45% decrease in the RBG was seen after the treatment with the higher dose of SOE, whereas a 44% decrease was observed with the lower dose as com¬pared to the diabetic control. Serum insulin was significantly increased (P<0.05) in all the treated groups as compared to the diabetic control. Plasma HbA1c was significantly decreased (P<0.05). The serum Triacyl Glycerol (TG) levels were signifi¬cantly decreased (P<0.05) in the treated rats as compared to the diabetic control. A significant increase in HDL-cholesterol (P<0.05) in the diabetic rats as a result of the 100mg/kg SOE treatment was a remarkable finding. Conclusion: SOE improves the glycaemic parameters in diabetic rats after a prolonged treatment. The serum TG levels were normalized on treatment. A higher dose of the extract could not alter the parameters significantly, except for HDL-C.
