Exogenous vasopressin reverses hyperactivity in the hypothalamus of Brattleboro rats. 1984

T L Krukoff, and F R Calaresu

We have previously described an increase of cytochrome oxidase (COX) activity in discrete hypothalamic nuclei of the Brattleboro rat (BR). The present experiments were done to investigate whether this increase in COX activity could be eliminated by administration of exogenous arginine vasopressin (AVP). Continuous infusion of AVP to BR for 7 days corrected the polyuria and the urine hypoosmolality, as expected, and it also eliminated the COX hyperactivity in the paraventricular nucleus and nucleus circularis of the BR hypothalamus. These results suggest that the hyperactivity of these nuclei in the BR is directly related to their inability to produce AVP.

D003576 Electron Transport Complex IV A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.

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.
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.

D014667 Vasopressins Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.
