The purpose of this study was to investigate the role of arginine vasopressin (AVP) on glucagon secretion in both normal and diabetic rats. Diabetes was induced by intravenous administration of 50 mg/kg streptozotocin, 14 days before pancreatic perfusion. Diabetic rats were maintained on insulin replacement therapy until approximately 48 h before the(More)
In vitro effects of a mixture of Escherichia coli heat-stable enterotoxins (STa and STb) on isolated jejunum of 3-week-old male pigs were studied, using everted intestinal sac techniques. Heat-stable enterotoxins increased chloride secretion and chloride absorption in everted intestinal sacs. The increase of secretory flux was greater than that for(More)
The effects of Escherichia coli heat-stable enterotoxin (ST) on chloride efflux rate were investigated in 3 fractions of enterocytes isolated in a villus-to-crypt gradient from porcine jejunum. There was no difference in chloride efflux rates between mature and immature cells from controls. Heat-stable enterotoxin significantly increased chloride efflux in(More)
