The effect of osmotic stimuli on prolactin secretion and renal water excretion in normal man and in chronic hyperprolactinemia. 1977

G Baumann, and S P Marynick, and S J Winters, and D L Loriaux

An osmoregulatory role for prolactin (PRL) in man has been postulated, and PRL secretion has been reported to be influenced by osmotic stimuli. Clinical observation, however, does not support this notion. The effects of water loading, hypertonic saline infusion and nicotine on serum PRL and on renal water metabolism were investigated in 6 normal subjects and in 8 patients with chronic hyperprolactinemia (four with and four without demonstrable pituitary tumors). None of the patients had thyroid, adrenal or vasopressin deficiency. Renal walter handling in these patients was indistinguishable from normal. Likewise, serum PRL was not affected by the stimuli employed in either the normal subjects or the patients. No correlation between degree or duration of hyperprolactinemia and renal water metabolism was found. It is concluded that PRL is not an important osmoregulatory hormone in man.

D006964	Hyperpituitarism	Disease of the glandular, anterior portion of the pituitary (PITUITARY GLAND, ANTERIOR) resulting in hypersecretion of ADENOHYPOPHYSEAL HORMONES such as GROWTH HORMONE; PROLACTIN; THYROTROPIN; LUTEINIZING HORMONE; FOLLICLE STIMULATING HORMONE ; and ADRENOCORTICOTROPIC HORMONE. Hyperpituitarism usually is caused by a functional ADENOMA.

D009538	Nicotine	Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.	Nicotine Bitartrate,Nicotine Tartrate
D009994	Osmolar Concentration	The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per liter of solution. Osmolality is expressed in terms of osmoles of solute per kilogram of solvent.

D010911	Pituitary Neoplasms	Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.

D011388	Prolactin	A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.
