title: [The effect of vagus and sypathetic nerves on blood flow in the swine stomach].
abstract: Porcine gastric blood flow (radioactive microspheres) was studied (aortic blood pressure controlled) under five conditions: control (n = 8), electric stimulation of the splanchnic nerves (n = 8) and the vagus nerves (n = 8), truncal vagotomy (n = 8), and gastric sympathectomy (splanchnicotomy, n = 5). Highly significant increase in corpus mucosa flow after vagal stimulation or gastric sympathectomy is antagonistic to changes after splanchnic stimulation and truncal vagotomyand is often contrary to changes of the antrum mucosa. This might be an explanation fir ischemic gastric lesions (stress ulcer) after stress-induced high sympathetic tone (1, 2) and stress ulcer prophylaxis by gastric sympathectomy (3, 4).
