Abstract: Objective: To investigate the effects of Shaosha-7 in rats with myocardial ischemia-reperfusion injury and its mechanisms. Methods: male SD rats were divided into sham operation group (n=10), myocardial ischemia-reperfusion injury group (n=10), low, medium and high dose of Shaosha-7 groups (n=10), and positive drug group (n=10). The rats of Shaosha-7 (low, medium and high dose) groups were treated with Shaosha-7 at the doses of 0.4, 0.8 and 1.6 g/kg respectively, once a day for 15 days. The rats of positive drug group were treated with 0.3 g/kg Danshen, once a day for 15 days. The rats of the sham operation group and myocardial ischemia-reperfusion injury were treated with 2 ml/100 g distilled water, once a day for 15 days. After 15 days, the rats of the model group and the treatment group underwent thoracotomy and ligation of coronary artery for 30 minutes, then thoracic cavity was closed after reperfusion. Rats in six groups were executed electrocardiographic examination and their hearts were taken for Hematoxylin-Eosin (HE) staining and 2, 3, 5-triphenyltetrazolium chloride (TTC) staining to observe infarct area and myocardial pathological changes. The contents of cTnI, CK-MB, LDH, MDA, SOD, GSH-Px, TNF-α, IL-18, IL-6 and IL-1 β in serum were detected by ELISA. The expression of NF-кB was detected by immunohistochemistry. Results: Compared with the sham operation group, the infarct size, the levels of cTnI, CK-MB, CK-MB, LDH, MDA, GSH-Px, TNF-α, IL-18, IL-6, IL-1β and NF-кB were increased and the content of SOD were decreased in rats with myocardial ischemia-reperfusion injury. Compared with the rats with myocardial ischemia-reperfusion injury, Shaosha-7 improved the arrhythmia and pathological changes, reduced the infarct area, decreased the contents of cTnI, CK-MB, LDH, MDA, GSH-Px, TNF-α, IL-18, IL-6, IL-1 β, increased the content of SOD, decreased the expression of NF-кB. Conclusion: Mongolian medicine Shaosha-7 can effectively alleviate myocardial ischemia-reperfusion injury in rats. This study provides a theoretical basis for the treatment of myocardial ischemia-reperfusion (I/R) injury with Shaosha-7.

Key words: Mongolian medicine shaosha-7, myocardial ischemia-reperfusion injury, oxidative stress, inflammation, rats
