title: [Mechanism of oliguria in experimental hypoparathyroidism].
abstract: Diuresis was found to diminish considerably in dogs with removed (by enucleation or burning out) parathyroid glands chiefly on account of intensified tubular reabsorption. In the mechanism of oliguria in hypoparathyroidism a definite role is played by hypocalciemia. An acute reduction of blood calcium in intact dogs also suppressed diuresis. Dogs with hypoparathyroidism displayed a marked elevation of blood plasma antidiuretic activity and a high level of reabsorption of osmotically free water. Intravenous injection of adrenoblocker dihydroergotamine eliminated the suppression of diuresis in the parathyroprived dogs. Apparently, a definite role in the origin of oliguria belonged to substances of adrenergic nature.
