Biphasic vasoconstriction of the rabbit ear artery.
Sympathetic nerve stimulation and intralummal norepinephrine infusion for more than 15 seconds produced a biphasic response in the isolated rabbit ear artery perfused with RREBS solution. This response consisted of an initial rapid constriction (phase A), which was followed by partial relaxation, and a final slowly developing constriction (phase B), which lasted for the duration of nerve stimul...
متن کاملBiphasic constrictor response of the rabbit ear artery.
The perfused rabbit ear artery shows a biphasic contractile response to intraluminal norepinephrine and sympathetic nerve stimulation. The peak of the first phase occurs after approximately 10 seconds of exposure to NE, and the second, after IK to 2 minutes. The magnitudes of the two responses are similar. The time course of the second phase of contraction is similar to the rate of saturation o...
متن کاملComparison of constrictor responses of the rabbit ear artery to norepinephrine and to sympathetic nerve stimulation.
The perfused isolated rabbit ear artery was used as a vascular model to compare the constrictor responses to exogenous and endogenous norepinephrine. The aim of the study was to estimate the concentrations of norepinephrine reaching the smooth muscle of the artery during sympathetic nerve stimulation. The artery was perfused so that exogenous norepinephrine was introduced exclusively from the a...

متن کاملThe Comparison of Oral Mucosal Clinical Reactions to PVDF and Silk Sutures in Albino Rabbit
This study was carried out in order to compare the oral mucosal reactions to silk and poly vinylidene fluoride (PVDF) suture materials in albino rabbit. Twenty-one mature male albino rabbits were selected and under general and local anesthesia suture materials were placed randomly at right and left side of vestibular area of maxillary jaw. The animals were divided into three equal groups based ...
