説明

Daily treatment with 5 or 500μg of estradiol benzoate of male adult rats for 7 days did not change the activity of testosterone 5α-reductase in the ventral prostate, while the activity decreased slightly in the dorsolateral prostate. The activity of alkaline phosphatase was increased by 60% over the respective control in the ventral prostate from rats treated with the larger dose of estrogen, but the estrogen treatment did not affect the alkaline phosphatase activity in the dorsolateral prostate. On the contrary, the estrogen treatment evoked three-fold elevation in the arginase activity of the dorsolateral prostate in contrast to the decreased, arginase activity in the ventral prostate following estrogen administration. From these results, it was concluded that the alterations in some enzyme activity of the ventral and the dorsolateral prostates evoked by estrogen treatment were different from those obsorved in the respective lobes from castrated animals, although both estrogen administration and castration induced atrophy of the tissue. Furthermore, it might be also worthwhile to mention that the ventral and the dorsolateral prostates of rats responded in a different manner to estrogen administered.
