Comparative effect of Beta blocker-Atenolol and Murraya koenigii (L.) spreng (Curry leaves) on cardiac enzyme (CK-MB) level in male albino rats

Abstract

Murraya koenigii (L.) spreng (curry leaves) have traditionally been used for its various medicinal properties. The current study was conducted to assess the comparative effect of Murraya koenigii (L.) spreng (curry leaves) and market available beta blocker drug Atenolol on cardiac enzyme (CK-MB) level in male albino rats. Out of total 26 locally bred male Albino Wistar rats (180 to 200gm weight) two rats were treated with only voltral for dose adjustment. Remaining 24 rats were randomly categorized into following 1 control (C) group and 3 experimental groups Model (M), Test 1 (T1) and Test 2 (T2) containing 6 rats in each group. Rats in C group were orally fed by 0.9% saline solution while rats of M and both test groups T1 and T2 were orally treated with voltral tablet (30mg /kg body weight) for three weeks to increase the level of CK-MB heart enzyme. After voltral treatment rats in test group T1 were treated orally with Atenolol (30 mg/kg body weight) and T2 with Murraya koenigii (L.) spreng (curry leaves) extract (180 mg/kg body weight) for last three weeks. Results show that rats treated with Atenolol showed a decrease in level of heart enzyme as compare to M group, while Murraya koenigii (L.) spreng treated rats group T2 showed more significant decrease of heart enzyme (CK-MB) level as compared to M and T1 groups with significantly improved behavioral activity including increased locomotor activity, short-term memory and reduction in depression. These results demonstrate that natural herbal treatment by curry leaves extract play an effective role in lowering the cardiac enzyme (CK-MB) level to its normal range which helps reducing the risk of CVD and CHD.
