硒对汞致红细胞膜上AT Pase活性变化的拮抗作用

The Antagonistic Effect of ATPase Activity on the Membrance of RBC between Selenite and Mercury

选用健康雏鸡 2 5 0只作实验动物 ,采取分组对比的方法 (对照组 ,中毒组 ,三个水平的硒保护组 ) ,研究汞对红细胞膜上ATPase活性的影响以及硒与汞之间的相互作用效应。实验结果表明 :汞严重影响红细胞膜上ATPase活性 ,早期略有升高 (P >0 .0 5 ) ,以后显著降低 (P <0 .0 1) ,从而说明汞损伤生物膜系统 ,使其功能失常 ;

day old chickens were randomly divided into five groups(1 mercury poisoning group,3 groups with different level selenite protecting from mercury poisoning,and 1 control Group).Study the effect of ATPase activity on the membrance of RBC from mercury and intraction between selenite and mercury.The results were shown as follows:Mercury could affect ATPase activity.The ATPase activty increased slighly and reduced significently following.That proved:mercury did harm to thebiological membrance system.The selenite could antagonistic change of ATPase activity on the membrance of RBC from mercury.
