摘　　要：目的:观察海水对兔眼晶状体Na+,K+-ATP酶及Ca2+,Mg2+-ATP酶功能的影响。方法:在兔眼前房内注入0.2ml海水后不同时间摘除眼球,分别测定其Na+,K+-ATP酶及Ca2+,Mg2+-ATP酶活性。结果:海水组兔眼晶状体两酶活性均先降低,再增高,最终完全或部分恢复正常;而对照组两酶的活性与正常组比较没有显著差别。结论:海水可使晶状体的Na+,K+-ATP酶及Ca2+,Mg2+-ATP酶的活性不同程度受损。Objective： To investigate the changes of Na^＋, K^＋-ATP ase and Ca^2＋, Mg^2＋-ATP ase in lens of rabbits with seawater injected into anterior chambers.Methods： After 0.2 ml seawater were injected into anterior chambers, the rabbit＇s eye hails were enucleated respectively in deferent time to examine the activity of Na^＋, K^＋-ATP ase and Ca^2＋, Mg^2＋-ATP ase in lens by biochemistry method.Results： The activity of Na^＋, K^＋-ATP ase and Ca^2＋, Mg^2＋-ATP ase in lens of seawater group decreased significantly at first, then increased and recovered partly or completely at last.No significant difference of the activity of two kinds of enzyme in lens was found between control group and normal group.Conclusion： The activity of Na^＋, K^＋-ATP ase and Ca^2＋, Mg^2＋-ATP ase in rabbit lens are damaged in deferent degree with seawater injected into anterior chamber.
