Intracranial section of the glossopharyngeal and upper roots of the vagus nerves has been recommended, the cardiac dysrhythmia being controlled with atropine, isoprenaline, or transvenous pacemaker. Carbamazepine is known to relieve the pain of uncomplicated glossopharyngeal neuralgia.2 In our first patient the combination of carbamazepine and demand pacemaker abolished both pain and syncope wi...

In contrast to previous opinions, recent investigations have suggested that increasing heart rate (HR) with atropine when moderate sinus bradyeardia accompanies acute myocardial infarction is not necessarily beneficial. To further characterize the influence of vagally mediated changes in HR during ischemia, we evaluated the effects of atropine and of electric stimulation of the vagus nerves on ...

In this study, the effects of carotid chemoreceptors on reflex tracheal constriction were investigated in anesthetized, paralyzed, and artificially ventilated mongrel dogs. Reflex tracheal constriction was measured as changes in the intratracheal pressure of an air-filled balloon introduced into the rostral side of the transected trachea. A hypoxic condition was produced by ventilating the dog ...

Introduction American lung association report,there were 1.8 million emergency department visits and 3,816 deaths per year attributable to asthma [1]. according to (GINA2012) the role of complementary and alternative medicine in adult asthma treatment are limited because these approaches have been insufficiently researched and their effect are largely unproven [2]. The parasympathetic nervous s...

Although it has been shown that the vagus nerves may carry impulses mediating decreases in the rate of aldosterone secretion (1), no equivalent pathway has been demonstrated which might mediate increases in aldosterone secretion. Because of evidence that aldosterone secretion may be increased by some function of a decreased intravascular volume (2), and the evidence cited above that this increa...

IIJIMA, T., MOTOMURA, S., TAIRA, N. and HASHIMOTO, K. Effects on A-V Conduction of Tetrodotoxin Selectively Injected into the A-V Node Artery of the Dog. Tohoku J. exp. Med., 1972, 107 (1), 99-100 „Ÿ Tetrodotoxin was injected selectively into the A-V node artery of the dog heart in situ, of which both vagi and both cardiac nerves were cut. Tetrodotoxin at doses of 1 to 3 μg abolished effects of...

? Previous studies have shown that the NO -cGMP pathway may be functionally relevant in the nodose ganglion and at afferent terminations of the vagus nerve. The technique of unilateral vagal ligations, using double ligatures, was combined with the techniques of NADPH-diaphorase histochemistry, as an index of nitric oxide synthase (NOS) activity, and autoradiography using the radioligands 3 3 [ ...

PURPOSE Perineal transposition of the antropyloric valve following an anorectal excision as a substitute for a permanent colostomy has recently been reported in humans. However, the problem of neural control still remains in these patients. Our aim herein was to study the anatomical feasibility of an anastomosis between the pudendal nerve branches (inferior rectal nerve) innervating the externa...
