Abstract

The effects of estradiol benzoate (E2B) at a dose of 50 micrograms/day/rat for 15 days were investigated on ascorbate metabolism, steroidogenesis, protein, cholesterol levels of testis, adrenal and serum testosterone, LH and FSH profiles of rats. The data revealed that E2B manifested a direct effect on testicular and probably adrenal steroidogenesis. But serum gonadotrophin levels remained unchanged. The treatment also brought about a decline in ascorbate metabolism, activities of 3 beta and 17 beta hydroxysteroid dehydrogenases and alteration in protein level concomitant with the accumulation of cholesterol in both steroidogenic organs. Estrogen treatment was more effective in adult male rats than in the immature ones.

苯甲酸酯雌二醇对未成熟和成年雄性大鼠激素谱和甾体生成器官的影响。
研究了苯甲酸雌二醇(E2B) 50微克/天/只,连续15 d对大鼠睾丸抗坏血酸代谢、甾体生成、蛋白质、胆固醇水平、肾上腺素和血清睾酮、LH和FSH水平的影响。数据显示,E2B表现出对睾丸和肾上腺类固醇生成的直接影响。但血清促性腺激素水平保持不变。治疗还导致抗坏血酸代谢下降,3 β和17 β羟基类固醇脱氢酶活性下降,蛋白质水平改变,同时胆固醇在两个类固醇生成器官中积累。雌激素对成年雄性大鼠的治疗效果优于未成熟雄性大鼠。
