Production of aldosterone in male rats with inherited diabetes insipidus (Brattleboro strain). 1984

J P Laulin, and E A Ezzarani, and R Brudieux

Plasma concentration, metabolic clearance rate and in vitro adrenal production of aldosterone were measured in Brattleboro male rats with inherited diabetes insipidus (DI) and in Long-Evans male rats (LE) as controls. Plasma concentration of aldosterone was significantly lower (-48.3%) in DI rats than in LE rats. Metabolic clearance rate of aldosterone was not statistically different between Brattleboro and Long-Evans rats, suggesting that the in vivo production rate of aldosterone was reduced by half in DI rats. Conversely, the basal in vitro production of aldosterone by adrenal tissue was similar in the two groups of rats. The reason for impairment of the in vivo production of aldosterone by Brattleboro rats congenitally lacking vasopressin is discussed. It is suggested that despite possibly indirect influence on the factors involved in the control of aldosterone secretion, mainly ACTH and potassium, vasopressin effects might occur in situ on the adrenal glomerulosa cells.

D009929 Organ Size The measurement of an organ in volume, mass, or heaviness. Organ Volume,Organ Weight,Size, Organ,Weight, Organ
D011910 Rats, Brattleboro A mutant strain of Rattus norvegicus used in research on renal function and hypertension and as a disease model for diabetes insipidus. Brattleboro Rats
D003919 Diabetes Insipidus A disease that is characterized by frequent urination, excretion of large amounts of dilute URINE, and excessive THIRST. Etiologies of diabetes insipidus include deficiency of antidiuretic hormone (also known as ADH or VASOPRESSIN) secreted by the NEUROHYPOPHYSIS, impaired KIDNEY response to ADH, and impaired hypothalamic regulation of thirst.
D000311 Adrenal Glands A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.

D000450 Aldosterone A hormone secreted by the ADRENAL CORTEX that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium. Aldosterone, (+-)-Isomer,Aldosterone, (11 beta,17 alpha)-Isomer
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
