Intestinal infusion of endotoxin in adrenalectomized calves.
Four adrenalectomized calves, 3 to 4 months old, were allowed to develop adrenocorticosteroid insufficiency and then were given 50 mg of Escherichia coli endotoxin by infusion via cannula into the duodenum. Several physiologic variables were studied to detect changes indicative of endotoxemia. It is concluded that adrenocorticosteroid insufficiency in calves is not an independent factor allowing an intestinal source of endotoxin to cause the development of clinical signs and physiologic changes characteristic of endotoxemia.
