It is often implied that chromophobe adenomas of the hypophysis are without significant endo crine function (11). However, some hypophyseal tumors experimentally produced in mice by de stroying their thyroids with I131 have been de scribed as functioning chromophobe adenomas (9, 10). A review of the literature on the effects of thy roid deficiency in laboratory animals reveals wide discrepancie...

The branching pattern of the Aa. carotes internae and the macroscopic blood supply to the hypophysis and hypothalamus of the ostrich were studied on ten dissected acrylic vascular-injected heads and ten corrosion preparations of acrylic vascular casts of the head. The A. carotis cerebralis was found to be the only source of blood supply to the hypophysis and hypothalamus. The neurohypophysis wa...

Injections of extracts of the hypophysis cerebri have been tested by Szymonowicz and by Oliver and Sch~ifer during the course of their well-known experiments upon the effects of extracts of the adrenal glands. Szymonowicz * states that in two experiments of this kind, made upon dogs, he obtained a slight fall of blood pressure and a quickening of the heart beat, just the reverse of the cardiac ...
