Diuretic and antidiuretic hormones

Antidiuretic hormones.

There are at least 3 antidiuretic hormones. Arginine vasopressin is the antidiuretic hormone of most mammals, including man. This function is served by lysine vasopressin in the pig, and by arginine vasotocin in birds, reptiles and amphibians. All 3 hormones are closely related chemieally and act on the kidney in a similar inanner. Arginine vasotocin also exists in fish, in which the antidiuret...

Evidence for the existence of diuretic and anti-diuretic hormones in locusts.

Medullary collecting-duct function in antidiuretic and in salt- or water-diuretic rats.

SONNENBERG, H. Medullary collecting-duct function in antidiuretic and in saltor water-diuretic rats. Am. J. Physiol. 226(3): 501-506. 1974.-Microcatheterization of the medullary collecting duct of adult rats was used to study the contribution of water, sodium, and potassium transport in this nephron segment to urinary excretion. In antidiuresis medullary reabsorption of fluid and sodium was 50/...

Diuretic effect of hypoxia, hypocapnia, and hyperpnea in humans: relation to hormones and O(2) chemosensitivity.

We studied the contributions of hypoxemia, hypocapnia, and hyperpnea to the acute hypoxic diuretic response (HDR) in humans and evaluated the role of peripheral O(2) chemosensitivity and renal hormones in HDR. Thirteen healthy male subjects (age 19-38 yr) were examined after sodium equilibration (intake: 120 mmol/day) during 90 min of normoxia (NO), poikilocapnic hypoxia (PH), and isocapnic hyp...

An antidiuretic peptide (Tenmo-ADFb) with kinin-like diuretic activity on Malpighian tubules of the house cricket, Acheta domesticus (L.).

Acheta domesticus is reported to have an antidiuretic hormone that reduces Malpighian tubule secretion. Identified peptides known to work in this way (Tenmo-ADFa and ADFb, and Manse-CAP(2b)) were tested as candidates for the unidentified hormone, along with their second messenger, cyclic GMP. Only Tenmo-ADFb was active, but was diuretic, as was 8-bromo cyclic GMP. The activity of Tenmo-ADFb is ...
