Abstract:

INTRODUCTION: Berberine, an isoquinoline alkaloid isolated from the Berberis aristata, has been shown to display a wide array of pharmacological activities (hypoglycaemic and hypolipidemic).

AIM: The present study was designed to investigate whether these pharmacological properties translate into the cardioprotective effects of Berberine in the setting of diabetes mellitus.

MATERIALS AND METHODS: Necessary approval from the Institutional Animal Ethics Committee was taken for the study. Experimental diabetes was produced with single dose of Streptozotocin (STZ): 45mg/kg ip and myocardial infarction was induced by administering Isoproterenol (ISP): 85mg/kg, sc to rats on 35(th)&36(th) day. After the confirmation of diabetes on 7(th) day (>200mg/dl), Berberine (100 mg/kg) was administered orally to experimental rats from day 8 and continued for 30 days thereafter. Various anti-diabetic (Glucose, HbA1c), cardioprotective (CPK-MB), metabolic (lipid profile), safety {liver function (SGPT, kidney function (Creatinine)} and histopathological indices of injury were evaluated in Healthy Control, Diabetic Control and Berberine treated groups.

RESULTS: Administration of STZ-ISP resulted in a significant decrease in body weight (p<0.001), diabetic changes (increase in blood glucose, HbA1c), cardiac injury (leakage of myocardial CPK-MB), altered lipid profile, SGPT, creatinine levels (p<0.001) in the diabetic control group rats as compared to healthy control. Berberine treatment demonstrated significant antidiabetic as well as myocardial salvaging effects as indicated by restoration of blood glucose, HbA1c and CPK-MB levels (p<0.001) compared to diabetic control group. In addition, Berberine favourably modulated the lipid parameters (total cholesterol, triglycerides, HDL, LDL). Subsequent to ISP challenge, histopathological assessment of heart, pancreas and biochemical indices of injury confirmed the cardioprotective effects of Berberine in setting of diabetes. In addition, Berberine was found to be safe to the liver and kidney.

CONCLUSION: Berberine treatment produced myocardial salvaging effects in the setting of diabetes challenged with ISP induced myocardial necrosis. Cardioprotection may be attributed to anti-diabetic and hypolipidemic activities.
