Central injection of captopril inhibits the blood pressure response to intracerebroventricular choline.
In the present study, we investigated the involvement of the brain renin-angiotensin system in the effects of central cholinergic stimulation on blood pressure in conscious, freely moving normotensive rats. In the first step, we determined the effects of intracerebroventricular (icv) choline (50, 100 and 150 microg) on blood pressure. Choline increased blood pressure in a dose-dependent manner....

Blood pressure response in rats to intracisternal administration of choline.
Central administration of acetylcholine or nicotine to rats induces changes in blood pressure and heart rate via central chol inoceptor activation (1, 2). Physostigmine a cholinesterase inhibitor also modifies blood pressure and heart rate (3, 4). Thus, central cholinergic mechanisms may be physio logically involved in the central control of cardiovascular function. In the present experiments, ...

15 صفحه اولInteraction of intracerebroventricular injection of captopril and histamine on water intake in adult male Wistar rats
Several evidences have indicated that many nuclei in the brain have critical role in water intake. Angiotensin II is one of the most important neurotransmitters involved in regulation of fluid homeostasis. In this study, the interaction of i.c.v. injection of captopril and histamine on water intake in adult male water-deprived rats was investigated. Rats were implanted with guide cannula aimed ...
