The activities of ATP-ase, cytochrome oxidase and succinic dehydrogenase were studied histochemically in the Wistar rat endometrium and the vicissitudes of their activities and localization were compared in proestrus, estrus and diestrus.Clear microscopic findings were obtained which show marked cyclic changes of succinic dehydrogenase which have been reported to be difficult to be demonstrated by any histochemical procedures.Further the influences of estradiol on the activities of the above-mentioned enzymes were studied histochemically by administering 0.05, 0.5, 5.0, 50, 500, and 5, 000 gamma, per body weight of estradiol, and some morphological findings which show marked changes of the localizations of the enzymes, especially those of succinic dehydrogenase, were also obtained.
