Abstract

The effects of daily melatonin injections on female gonads in Rana ridibunda were examined. Melatonin-treated R. ridibunda maintained on a long photoperiod (18L:6D) had significantly smaller gonads than control animals. Thus, frogs injected daily with melatonin exhibited a substantial decrease in ovary weight when compared to saline-injected animals. Our findings suggest that melatonin exerts antigonadal effects in female Rana ridibunda.

摘要

研究了每日注射褪黑素对泽蛙雌性性腺的影响。在长光照周期（18小时光照：6小时黑暗）下饲养的经褪黑素处理的泽蛙，其性腺明显小于对照动物。因此，与注射生理盐水的动物相比，每日注射褪黑素的青蛙卵巢重量大幅下降。我们的研究结果表明，褪黑素对雌性泽蛙具有抗性腺作用。
