For the morphological classification of cell types in the anterior hypophysis of different vertebrates, cytological studies have been undertaken by many investigators, (S chOnemann 1892, Yamada '37a and '37b , Dawson and Friedgood '38, Romeis '40, Dawson '46, Goldberg and Chaikof f '52 and others) and it is believed, in a broad sense, that parenchymatous cells of the anterior hypophysis are com...

BACKGROUND AND PURPOSE Idiopathic intracranial hypertension is a headache syndrome characterized by increased CSF pressure. Compression of the hypophysis and distension of the optic nerve sheath are reliable imaging signs. The purpose of the study was to validate, in patients with idiopathic intracranial hypertension, MR imaging-based volumetric measurements of the optic nerve sheath and hypoph...

The pressor substance of the hypophysis is so marked in the pig fetus measuring 175 mm. that it seems probable that a fetus of this length is independent of the secretion of the mother's hypophysis.

The expression of the neural cell adhesion molecule, N-CAM, was examined in the anterior lobe of rat hypophysis by immunocytochemistry at light and electron microscope levels. In addition, N-CAM antigenic determinants present in adrenal medulla, anterior hypophysis and PC12 cells were compared by immunoblotting with those found in cerebellum. All secretory cells in the anterior hypophysis were ...

Of all the anterior hypophyses tested, those of the human produced the most marked diabetogenic action in the dog with its pancreatic tissue reduced to 4 gm., and in the hypophysectomized and pancreatectomized toad. The human hypophysis also produced diabetogenic action in the normal dog on daily doses of 1.26 mg. per kilo per day for 2 days. The hypophysectomized dog with its pancreas reduced ...

Adenoid cystic carcinoma (ACC) is a rare epithelial malignancy arising from secretory glands, particularly the salivary glands. It tends to invade nerves and has a high potential for distant hematogenous metastasis, especially to the lungs, bone, liver and brain. The breast and hypophysis are not common sites of ACC metastatic disease. Herein, we report a case of ACC of the head and neck region...

The spontaneous occurrence of chromophobe adenomas and focal hyperplasia in the rat hypophysis has been reported by Wolfe, Bryan, and Wright (I8), and by Oberling, Sanni6, and the Gu6rins (I3). Hyperplasia of chromophobic ceils and the development of chromophobe adenomas in the rat hypophysis following injection of estrogens have been described by Wolfe and Wright (O) , by Zondek (2o), and by M...

The aim of this study is to determine the morphometry hypophysis New Zealand rabbit by using computed tomography images and its topography according anatomical structures in cavum cranii. For purpose, head 12 (6 female, 6 male) Rabbits was scanned a prone position Multi-Detector Computed Tomography. Three-dimensional modeling obtained performed. Morphometric analysis hypophysis, three-dimension...

1. Removal of the hypophysis in adult rats is followed by progressive atrophy of the spleen. At the end of 2 months the ratio of spleen weight to body weight is one-half the normal. The administration of hypophyseal emulsion repairs to a considerable degree the atrophy of the spleen in such animals. 2. Hypophysectomy completely inhibits the regeneration of splenic tissue after partial splenecto...
