摘要
目的探索温度胁迫(高温和低温)情况下湖北钉螺体内细胞色素氧化酶和琥珀酸脱氢酶两种酶的含量变化情况。方法将钉螺随机分成对照组、低温组和高温组,分别放置于20℃、4℃和37℃环境中,24 h后取钉螺软体组织,测定各组钉螺细胞色素氧化酶和琥珀酸脱氢酶的含量。结果对照组、低温组和高温组三组钉螺软体组织中细胞色素氧化酶含量分别为(27.11±2.31)U/L、(21.90±0.32)U/L和(21.42±1.84)U/L,三组间不全相同,且差异有统计学意义(F=10.145,P<0.05);琥珀酸脱氢酶含量分别为(1.30±0.002)U/L、(1.24±0.05)U/L和(1.12±0.02)U/L,三组间不全相同,且差异有统计学意义(F=124.624,P<0.05)。结论湖北钉螺在温度胁迫状态下,其软体组织中细胞色素氧化酶和琥珀酸脱氢酶的含量均降低。
Objective To investigate the changes of cytochrome oxidase(COX)and succinate dehydrogenase(SDH)contents in Oncomelania hupensis(O.hupensis)under laboratory condition and temperature stress(high temperature and low temperature).Methods O.hupensis snails were randomly divided into control group(T=20℃),low temperature group(T=4℃)and high temperature group(T=37℃).Soft tissues of the snails were taken at 24 h after treatment by the different temperature to measure the changes of COX and SDH level in each group.Results The content of COX and SDH in the soft tissues was(27.11±2.31)U/L,(21.90±0.32)U/L and(21.42±1.84)U/L;(1.30±0.002)U/L,(1.24±0.05)U/L and(1.12±0.02)U/L,respectively for the control,low temperature group and high temperature group.The difference was significant among groups(F=10.145,P<0.05 for COX;F=124.624,P<0.05 for SDH).Conclusion COX and SDH contents tend to decrease in the soft tissue of O.hupensis under temperature stress.
