摘要: 对妇女血浆雌二醇(E2)水平与丙二醛(MDA)含量进行了观察。结果发现绝经期妇女较生育期妇女 E2降低,MDA 升高,且两者呈负相关性。在建立不同 E2水平的动物模型过程中观察到 E2水平的降低、升高可导致大鼠肝脏和子宫组织匀浆中 MDA 的升高和降低,子宫组织的这一变化尤其明显.试验结果提示:机体中 E2具有抑制脂质过氧化作用的能力,机体衰老可能与雌激素的降低而导致了组织中 MDA 的升高有关。

Abstract: Plasma estradiol(E2)and malondialdehyde(MDA)were examined in women,and the results demonstrated that E2 level decreased and MDA content increased in menopausal wo-men,showing a negative correlalivity between E2 and MDA.In animal experiment we found that E2 was decreased while MDA in liver and uterine homogenates was increased,adminis-tration of estrogen reversed the change of MDA in liver and uterus,and the range of change of MDA in uterus with E2 was more significant than that in liver.The results suggest that E2 may possess the antioxidative effect.Therefore,the manifestations of senescence are probably related with the increase of MDA resulting from the decrease of E2 level.

Key words: estrogen, malondialdehyde(MDA), lipid peroxidation
