thyroid hoemones effect gastric acid and pepsin secretion.however exact machanism(s) are not clear.this study was performed to compare the effect of vagal stimulation on acid an pepsin secretion in hypothyroid,hyperthyroid and control rars.each group consisted of 8 male and female rats(N-mari) weighing 246+_9 gr.hypo and hyperthyroid states were induced by administretion of methimazol (50mg/l i...

We determined the influence of differences in the time of initiation of sympathetic and vagal stimulation (both at 10 Hz) on the cardiac autonomic interactions in 16 open-chest anesthetized dogs. We always ended the concurrent sympathetic and vagal stimulations simultaneously. Sympathetic stimulation alone for 1 minute increased heart rate by 90 +/- 7 (mean +/- SEM) beats per minute, and vagal ...

It is commonly believed that vagally-mediated bradyeardia predisposes to ventricular fibrillation (VF) during acute myocardial ischemia. Recent experimental studies, however, have shown that bradycardia and vagal stimulation independently raise the threshold for electrically induced VF in the ischemic canine heart. To determine the influence of vagal stimulation on the spontaneous development o...

In the canine isovolumetric left ventricle preparation, stimuli were applied to the efferent end of a transected cervical vagus nerve. The changes in left ventricular systolic pressure in response to vagal stimulation were compared under control conditions and when ventricular contractility was enhanced by various kinds of inotropic stimulation—left stellate ganglion stimulation, paired pacing,...
