Prolactin secreting pituitary carcinoma.
A man with a prolactin secreting pituitary carcinoma was treated by surgery and radiotherapy. Persistent hyperprolactinaemia partially responded to oral bromocriptine for four years. Serum prolactin then rose considerably with rapid, invasive tumour recurrence. Cytotoxic chemotherapy halted tumour progression for twelve months before fatal spread throughout the brain. Failure to normalise serum...
متن کاملProlactin Secreting Pituitary Adenomas
Correspondence to: Ioana Muntean, e-mail: [email protected] ABSTRACT. Hyperprolactinemia has different etiologic forms, among them, the prolactin-secreting pituitary tumors represent an important entity. In our study, were analyzed the clinical aspects, diagnostic procedures and therapeutical approach of 31 cases of prolactinomas (F/M ratio = 27/4) hospitalized in the Clinic of Endocrinol...
متن کاملBrain angiotensin II stimulates release of pituitary hormones, plasma catecholamines and increases blood pressure in dogs.
1. The mechanisms of central angiotensin II blood pressure effects in conscious dogs on normal or sodium-deficient diets were examined. 2. The biosynthesis of brain angiotensin II in cerebrospinal fluid from its local precursor angiotensinogen was induced in vivo by injection of 0.5 unit of hog kidney renin through a chronically implanted cannula into the third brain ventricle in conscious dogs...
متن کاملGenistein-induced pituitary prolactin gene expression and prolactin release in ovariectomized ewes following a series of intracerebroventricular infusions.
The aim of the study was to evaluate whether genistein, a phytoestrogen commonly present in feed plants, affects prolactin release and its gene expression in the pituitary gland. In the experimental model, genistein was infused into the third ventricle (IIIv) of the brain in ewes during the short-daylight period (November-December), when the physiological plasma level of prolactin is low. Anima...
