摘　　要：在不同条件下测定两种SOD的酶活力并计算其相对性活力,以比较修饰SOD和天然SOD的稳定性.结果证明:修饰SOD比天然SOD耐酸、耐碱、耐热,在稀释空腹胃液中修饰SOD活力高于天然SOD。Under the various conditions of determination the activities and the relative activities,the stability of modified SOD and natural SOD was compared.The result showed that LASOD is more acidresisting,alkaliresisting and heatresisting than natural SOD,LASOD has higher activity than the natural one in diluted gastric juice on an empty stomach and LASOD is more stable than the natural one.
