Methods: One hundred male Sprague-Dawley rats were subjected to sham-operation or MI induced by ligating the left anterior descending coronary artery. The rats with MI were treated with vehicle, JSP 3 and 6 g/(kg.d), or Iosartan 10 mg/(kg.d) for 1 week. Results: Compared with the vehicle-treated MI rats, 6 g/(kg-d) 3SP reduced MI size 3 days after MI (P〈0.05), and attenuated the MI-induced increases in left ventricular end-diastolic and end-systolic dimension and decreases in fractional shortening and ejection fraction 1 week after MI (P〈0.05). In addition, 6 g/(kg·d) JSP and Iosartan were equally effective in reducing MI size and enhancing cardiac functional recovery. Conclusion: JSP reduces MI size and improves cardiac function after MI, suggesting that JSP has potential as a therapy for MI.展开更多
