Release of Adrenal Catecholamines by Angiotensln II
Several recent investigations have presented indirect evidence that angiotensin stimulates the release of adrenal medullary catecholamines. The following work was undertaken in an attempt to show in vivo angiotensin stimulation of the adrenal medulla by analysis of plasma catecholamines. Mongrel dogs, anesthetized with pentobarbital, were infused for 10 min with doses of 0.025, 0.05, and 0.1 fi...

متن کاملRelease of catecholamines from perfused cat adrenal gland by veratridine.
Experiments were undertaken to verify the existence of fast sodium channels in the adrenal chromaffin cell membrane and to assess their contribution to the physiological release of catecholamines. We have used veratridine to activate sodium channels. Veratridine causes secretion of catecholamines from perfused cat adrenal gland. Secretory response to veratridine is calcium dependent and abolish...
متن کاملIntracellular pH-regulatory mechanisms in pancreatic acinar cells. II. Regulation of H+ and HCO3- transporters by Ca2(+)-mobilizing agonists.
Pancreatic acini loaded with the pH-sensitive dye 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein were used to examine the effect of Ca2(+)-mobilizing agonists on the activity of acid-base transporters in these cells. In the accompanying article (Muallen, S., and Loessberg, P. A. (1990) J. Biol. Chem. 265, 12813-12819) we showed that in 4-(2-hydroxyethyl)-1-piperazine-ethanesulfonic acid (HEPES...
متن کاملM3 Subtype of Muscarinic Receptors Mediate Ca2+ Release from Intracellular Stores in Rat Prostate Neuroendocrine Cells
Our previous studies document the expression of adrenoceptors and purinoceptors in the rat prostate neuroendocrine cells (RPNECs). However, a direct investigation of the receptors for acetylcholine (ACh) is still lacking in the prostate neuroendocrine cells. RPNECs were freshly isolated from the ventral lobes of rat prostate by using collagenase. Effects of ACh and various muscarinic antagonist...
