The anti-inflammatory effect of catecholamines in the peritoneal cavity and hind paw of the mouse.

abstract：:1. The vasodilator response to acetylcholine (ACh) was investigated in the aortic arches of the leopard frog (Rana pipiens). 2. With adrenaline pre-constricted preparations, both ACh and sodium nitroprusside (SNP) caused concentration-dependent relaxations. Damage to the endothelial layer abolished relaxations to ACh,...
