摘要: 为观察不同价态的锰染毒后对18月龄大鼠体内脂质过氧化的影响,将大鼠经腹腔分别注射氯化锰(MnCl2·4H2O,Mn2+)、醋酸锰(C6H9O6Mn·2H2O,Mn3+),连续染毒1个月后,测定大鼠脑、肝、心肌组织中的丙二醛(MDA)质量摩尔浓度及超氧化物歧化酶(SOD)活性。结果:不同价态锰染毒后大鼠脑组织MDA质量摩尔浓度、SOD活性与对照组相比有显著性差异(P<0.05);肝组织的SOD活性与对照组相比有显著性差异(P<0.05),MDA的质量摩尔浓度只有Mn2+组与对照组相比有显著性差异(P<0.05);而心肌组织的MDA质量摩尔浓度、SOD活性Mn2+组、Mn3+组与对照组相比均无显著差异。提示:不同价态锰染毒对不同组织的毒性效应是不同的

Abstract: The aim was to u nderstand the effects of manganese with different valence on the status lipid pe roxidation and antioxidation in rats. Methods: mice were treated with MnCl2 or C6H9O6 Mn·2H2O or sterile saline by intraoeritioneal injection for one month, then the concentration of MDA and the activity of SOD in brain, liver and heart were determined. In the rat's brain treated with the two different manganese, the concentration of MDA increased with the decrease of SOD, contras ted with those treated with sterile saline. In liver, to those samp les treated with MnCl2, the concentration of MDA and the activity of the SOD i ncreased and decreased respectively, contrasted with the other two groups. In he art, however, no difference was fond in three groups. The results show that the toxicity of manganese with different valence on the old rat's different organizes are vari ous.
