RESUMEN
AIM The preventive effects of safflor yefflor (SY) on myocardium injury of myocardium ischemic reperfusion (I/R) was studied. METHODS The contents of MDA activity of SOD,as well as the activity of creatine phospho kinase(CK) and lactate dehydrogenase(LDH) were determined in rat models injured by I/R. RESULTS SY could reduce the activities of CK and LDH ,decrease the the content of MDA in plasmo, and increase the activities of SOD. CONCLUSION SY may obviously prevent the rat I/R model which may be related to its anti lipoperoxidation.
RESUMEN
Aim To observe the effects and mechanism of safflor yellow on the experimental acute myocardial ischemia (AMI) model rats. Methods AMI model rats were induced by isoproterenol (10 mg?kg-1). The changes of indexes on hemodynamics such as MBP, LVSP, LVEDP and ?dp/dt_ max,the coronary artery flux(CF) and myocardia O_2 comption(MVO_2) in AMI model rats were observed respectively. Results The CF and MVO_2 in the heart muscle increased and decreased respectively the indexes of hemodynamics were improved in safflor yellow groups. Conclusion The results indicate that safflor yellow can inhibit the failure of heart function induced by AMI, increase the coronary artery flux and decrease MVO_2 significantly.
