HEMODYNAMICS OF THE STOMACH. 3. EFFECTS OF SALMONELLA TYPHOSA ENDOTOXIN ON THE RESISTANCE TO BLOOD FLOW

Abstract

Injection of endotoxin into the left gastric artery produced a rapid increase in gastric arterial pressure (100%) and coronary venous pressure (200%) . Arterial pressure remained elevated longer than venous pressure. These responses were blocked by locally infused phentolamine When the gastric circulation was isolated, endotoxin failed to increase gastric vascular resistance, whether injected directly into the stomach or systemically. It is concluded that these responses are probably induced by a distant release of catecholamines.
