摘要

在4周的时间里,对未受影响的大鼠(对照组)和阉割的大鼠进行了饮食限制(正常水平的50%)的研究。限制饮食导致动物停止生长。在对照组和阉割大鼠之间没有观察到差异。然而,喂食不足会使未受影响的大鼠睾丸重量减少。组织化学观察显示,限制饮食的动物上颌下腺中色氨酸(睾酮依赖蛋白存在的标志)减少。在饲喂正常饲料的动物中,阉割显著降低了腺体重量,以及小管和腺泡的直径。当喂食限制饮食的动物进行比较时,在小管和腺泡的直径或上颌下腺的重量方面没有发现显着差异。

Effects of a restricted diet on the submaxillary gland of intact and castrated male rats.

Effects of diet restriction (50% of normal) during 4 weeks were studied in intact (controls) and castrated rats. A restricted diet led to cessation of animal growth. No differences were observed between controls and castrated rats. However, underfeeding produced a reduction of testicular weight in intact rats. Histochemical observations showed a reduction of tryptophan (a marker of the presence of testosterone-dependent protein) in the submaxillary gland from animals fed a restricted-diet. In animals fed a normal diet, castration reduced significantly the gland weight, as well as the diameter of tubules and acini. When animals fed a restricted-diet are compared, no significant differences were found in the diameter of tubules and acini or in the weight of submaxillary glands.
