Notes	It is well recognized that gonadotropic function of the adenohypophysis is regulated by the hypothalamus in the domestic fowl. The present study deals with cytological changes of the adenohypophysis and the quantitative variation of PAS positive contents in the gland following the hypothalamic lesion in the White Leghorn cocks. Adenohypophysis, testes and the accessory organ weights were markedly decreased after the electrolytic lesion involving the basal tuberal or posterior median eminence region of the hypothalamus. Obvious cytological degeneration of basophils in the adenohypophysis was also observed in these cocks, and PAS positive contents in the cytoplasm of the cell were decreased significantly in microspectrophotometrical measurement. It is concluded from these results and the atrophic state of gonadal organs that the gonadotropic hormone output from the hypophysis after the injury of basal tuberal or posterior median eminence region must be at a very low level in consequence of disruption or at least great impairment of neural and vascular connexions between adenohypophysis and the hypothalamus.
