摘    要:为了探究腹腔注射贝类毒素OA对小鼠肝脏还原性谷胱甘肽(GSH)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)的影响,采用对一月龄的小鼠腹腔注射不同浓度的OA,24h后取其小鼠肝脏测定还原性谷胱甘肽(GSH)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)各项指标。结果表明,测定注射OA毒素各剂量组的超氧化物歧化酶(GSH)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)3项指标均显著低于对照组。其中,GSH高剂量组和中剂量组差异性不显著。CAT高剂量组(96μg/h)、中剂量组(48μg/kg)、低剂量组(24μg/kg)各组变化显著,呈现一定的剂量-效应关系,SOD高中低各组差异性不显著。因此,在小鼠染毒OA24h后,还原性谷胱甘肽(GSH),超氧化物歧化酶(SOD),过氧化氢酶(CAT)这3项指标均受到了显著性抑制作用,说明这3项指标对毒素OA较为敏感,其中CAT呈现了显著的剂量一效应关系。

关 键 词:大田软海绵酸(okadaic  acid,OA)  还原性谷胱甘肽(GSH)  过氧化氢酶(CAT)  超氧化物岐化酶(SOD)  小鼠

Abstract:To explore the influence of reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) in liver of mice by intraperitoneal injection of shellfish toxin OA, activities of GSH, CAT and SOD of one-month mice liver after intraperitoneal injection of different concentrations of OA for 24 h were assayed. Results showed that the numbers of reduced glutathione ( GSH), the activities of catalase (CAT) and superoxide dismutase (SOD) by injection of OA toxin were lower than those in the control group. The difference of GSH was not significant, however, the difference of catalase (CAT) was significant between the treatment group and the control grOUD.
Keywords:okadaic acid  glutathione GSH  catalase  superoxide dismutase  mice
