    Abstract:
    OBJECTIVE: To study the effect of composite Radix Salviae Militiorrhizae injectiion on myocyte apoptosis in experimental acute myocardial infarction of rabbits. METHODS: The models of acute myocardial infarction were made with rabbits. The method of terminal deoxynucleotidyl transferase mediated dUTP nick end labeling was used to explore myocardial cell apoptosis in different injury area of acute myocardial infarction. The activities of plasma superoxide dismurase and the contents of serum malonic aldehyde were determined. RESULTS: When rabbits were in the condition of acute myocardial infarction, there were myocyte apoptosis in the area of ischemia reperfusion injury and the area of infarction. The number of myocyte apoptosis and the myocyte rate in control group and composite Radix Salviae Militiorrhizae injectiion treated group were higher than in sham-operated group (P < 0.001). In the area of ischemia reperfusion injury the number of myocyte apoptosis and the myocyte rate in composite salvia militiorrhiza-treated group were lower than in control group (P < 0.05). The activity of plasma superoxide dismurase in composite salvia militiorrhiza-treated group was higher than in control group (P < 0.05), but lower than in sham-orerated group (P < 0.001). The content of serum malonic aldehyde in composite Radix Salviae Militiorrhizae injectiion treated group were lower than in control group (P < 0.05), but higher than in sham-operated group (P < 0.01). CONCLUSION: Composite Radix Salviae Militiorrhizae injectiion could reduce the number of myocyte apoptosis in the area of ischemia reperfusion injury, which maybe explained by the increase of the activity of plasma superoxide dismurase and the decrease of the contents of serum malonic aldehyde.
