Abstract: | Intranuclear vacuoles and membranes have been observed in mammotrophs of female Mongolian gerbils. Testosterone injection increases the number of cells containing inclusions (1·77±008 inclusions per field in testosterone-injected animals and 0·38±0·05 inclusions per field in controls). Testosterone may well be converted to some other compound which in turn induces the inclusions. Ovariectomy presumably prevented such a conversion inasmuch as testosterone was ineffective in increasing the number of inclusions in ovariectomized gerbils. Neither did the injection of dihydrotestosterone, the biologically active form of testosterone in some organs, increase the number of cells containing intranuclear inclusions. |
