Semecarpus anacardium is a commonly used drug in the Siddha system of medicine for curing various metabolic disorders. The cardio protective effect of the drug in Type 2 diabetes-induced cardiovascular complications was studied in rats by feeding them with a high fat diet for 2 weeks followed by intra peritoneal injection of streptozotocin at a moderate dosage of 2*35 mg/kg/ b.wt 24 hr apart and leaving them for 8 weeks to develop cardiovascular complications. The effect of the drug was studied by analyzing levels of blood glucose, insulin, HbA1c, marker enzymes, the antioxidative enzymes and the levels of lipid peroxides in Type 2 diabetic rats. Diabetic rats were treated with SA at a dosage of 300 mg/kg/b.wt. for 8 weeks and the results were compared with diabetic rats treated with the combination therapy drugs metformin at a dosage of 100 mg/kg/b.wt and atorvastatin at a dosage of 10 mg/kg/b.wt for 8 weeks. The drug SA significantly decreased the blood glucose levels and also HbA1c levels while improving glucose tolerance at the same time. The levels of marker enzymes and lipid peroxides were significantly increased in diabetic rats when compared with control rats. On the other hand significant decreases in the levels of antioxidative enzymes were observed in diabetic rats. Upon treatment with the drug SA, all of these abnormalities were restored to near normalcy. The present study thereby establishes the protective effect of the drug against diabetes-induced cardiac damage.
