Nonspecific effects of ligands on the beta-adrenergic receptors in rabbit abdominal aorta in vitro.
The study was conducted on 30 New Zealand rabbits weighing 3-4 kg from which sample strips of the abdominal aorta were collected. The study investigated the in vitro reaction of rabbit aorta smooth muscle to ligands binding to beta-adrenergic receptors. The response of aortic strips to beta-adrenergic receptor agonists (dobutamine, isoproterenol, salbutamol) and the influence of beta-adrenergic...

15 صفحه اولBeta-receptor activity in aorta; variations with age and species.
Helically cut thoracic aortic strips (from rats, rabbits, and guinea pigs) in a state of low to moderate tone and under the influence of alpha-receptor blockade relaxed in response to isoproterenol. Propranolol blocked these relaxations. Helically cut thoracic aortic strips from cats and abdominal aortic strips from rats, rabbits, and cats were not relaxed by isoproterenol. In addition, aortic ...
متن کاملExperimental sympathetic activation causes endothelial injury in the rabbit thoracic aorta via beta 1-adrenoceptor activation.
Sympathetic activation appears to accelerate the development of atherosclerosis, an effect that may be inhibited by beta-receptor blockade. It is unclear, however, which mechanisms mediate this effect. In view of the significance attached to endothelial injury in the initial phases of atherogenesis, we decided to test whether sympathetic activation might lead to an increase in endothelial injur...
متن کاملBeta-2 adrenergic receptor
The beta-2 adrenergic receptor (β2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that interacts with (binds) epinephrine, a hormone and neurotransmitter (ligand synonym, adrenaline) whose signaling, via a downstream Ltype calcium channel interaction, mediates physiologic responses such as smooth muscle relaxation and bronchodilation. Unlike other adr...
