RESUMO
AIM: To observe protective effects of sanguis draxonis flavones on myocardial ischemia in rats and dogs. METHODS: Acute myocardial ischemia in rats was produced by iv pituitrin and ECG indexes were observed. Myocardial ischemia was induced by ligating coronary artery in anaesthetized dogs, and then EEC, CK,LDH, and LD in serum were determined respectively. RESULTS: J point and T wave in rats changed evidently after iv pituitrin, which was reversed by sanguis draxonis flavones (360, 180 mg?kg~ -1). In coronary artery ligation model, infraction range, △N-ST, △?-ST and some serum indexes (such as CK, LDH and LD) was decreased after ig sanguis draxonis flavones (120, 60, 30 mg?kg~ -1). CONCLUSION: Acute myocardial ischemia is protected effectively by sanguis draxonis flavones.
