【Abstract】ObjectiveTo explore the protective effect of ligustrazine on the ischemia-reperfusion injury of rat liver.
MethodsNinety-six healthy SD rats were divided randomly into three groups: sham operation group, ischemiareperfusion group（I/R group) and ischemia plus ligustrazine reperfusion group(therapy group).The plasm ALT,AST and LDH were measured before operation,at thirty minutes,six hours and twentyfour hours after operation. One week survival and liver pathological change of every group were observed, and the hepatocyte apoptosis index was measured simultaneously.
ResultsOne week survival of therapy group was higher than that of I/R group (P＜0.05). The plasm ALT,AST and LDH of therapy group and I/R group were higher than those of the sham operation group significantly (P＜0.05), and those of therapy group were lower than those of the I/R group (P＜0.05). Light microscopy indicated that the liver sinusoid and central veins were congested remarkably after operation, the hepatocyte necrosis in I/R group was more severe than that in therapy group, and the hepatocyte apoptosis index of I/R group was higher than that of therapy group (P＜0.05).
ConclusionThe protective effect of ligustrazine on ischemia-reperfusion injury of rat liver is obvious.
