置换

It was observed that not only histidine, but also histidine-Co and histidine-Ni could induce and substitute some Cu and Zn from Cu_2Zn_2SOD, eventually influence the activity of this metalloenzyme. Histidine- metal ion complexes have stronger ability than histidine to displace the bound metal ion from SOD. In addition, the amount of foreign metal ion binding to the SOD was less than that of metal ion lost from SOD. It obviously means that there was apoenzyme in the solution.

实验结果表明： Cu2Zn2SOD酶不仅与组氨酸，而且还可以与组氨酸－CoⅡ）和组氨酸－Ni(Ⅱ相互作用，Cu2Zn2SOD酶中的部分Cu和Zn被诱导和置换出来，并相应地影响了酶的活性；组氨酸－金属离子配合物的作用比组氨酸强，酶活性降低也更明显；酶中结合的外来金属离子的量比从酶上被诱导和顶替下来的金属离子的量要少，说明在溶液中有脱辅基酶的存在。

objective to investigate the curative effect of plasma exchangeto treat patients of organophosphrous pesticide.methods combine pe and routine treatment to cure30patients of organophosphrous pesticide,and compare the results with that of31patients of routine treatment.results the former group use less atˉropin and shorter hospitalization with higher cure rate and lower death rate.conclusion combined pe and routine treatment of treat patients of organophosphrous poison can decrease the dose of atropin,shorten the length of stay,raise the cure rate and ower mortality.so pe is an effective way for patients oforganophosphrous pesticide.

目的 探讨血浆置换治疗重症有机磷农药中毒的疗效。方法应用pe配合常规疗法治疗30例的疗效与31例对照组常规疗法作比较分析。结果 pe配合常规疗法较常规疗法治疗重症有机磷农药中毒，前者阿托品用量少，住院时间短，治愈率高，死亡率低。结论 pe配合常规疗法治疗重症农药中毒，可减少阿托品用量，缩短住院时间，提高治愈率，降低死亡率，因此pe不失为治疗重症农药中毒的一种有效的抢救措施。
