摘要
初步分析了低温胁迫下黑龙江林蛙肝脏超氧化物歧化酶(SOD)、乳酸脱氢酶(LDH)、6—磷酸葡萄糖脱氢酶(G6PDH)及酯酶(EST)酶活性的变化。结果表明:1℃组的黑龙江林蛙肝脏SOD、LDH—1及EST的酶活性显著高于14℃组(P<0.05),而2组的LDH、G6PDH及EST总酶比活力无显著性差异。为适应低温环境,黑龙江林蛙肝脏某些酶活性显著增加,维持了机体代谢的稳定。
An experiment was conducted to study the activities changes of superoxide dismutase （ SOD）, lactate dehydrogenase （LDH）, glucose-6-phosphate dehydrogenase （G6PDH） and esterase （EST） in Rana amurensis liver under low temperature. Results showed that the activities of SOD, LDH-1, and EST in R. amurensis liver at 1 degrees C were significantly higher than those of the liver at room temperature, but the total enzyme activity of LDH, G6PDH, and EST of the two groups were similar. The activities of some enzymes in R. amurensis liver increased to maintain a stable energy metabolism in order to survive under low temperatures.
