Abstract

During the critical period of receptor maturation within the first 5 days after birth female rats were treated with benzpyrene three times and their uterus estrogen receptor characteristic were examined in adulthood. Estrogen receptor density decreased significantly. There was no alteration in receptor affinity. Present experiment draws attention to the disadvantageous effect of aromatic hydrocarbons coming from the polluted air on steroid receptor development.

新生儿接触苯并芘会降低大鼠子宫雌激素受体的结合能力。
在雌性大鼠出生后5天内受体成熟的关键时期,用苯并芘治疗3次,观察其成年后子宫雌激素受体特征。雌激素受体密度明显降低。受体亲和力无明显变化。本实验关注了污染空气中芳香烃对类固醇受体发育的不利影响。
