To study the effects of Mn 2+ on the rat liver nuclei pre treated with Mn 2+ , AAS, MFS and UV were used to determinate the changes of contents of Mn, malondialdehyde (MDA) and superoxide dismutase (SOD) in rats.

• 为了探讨锰 (Mn)对细胞核的作用 ,分别应用原子吸收分光光度法 (AAS)、分子荧光分析法 (MFS)和紫外 可见分光光度法 (UV) ,测定腹腔注射二价锰 (Mn2 + )后大鼠肝细胞核中Mn、丙二醛 (MDA)和超氧化物歧化酶 (SOD)的含量。
