It has been suggested that the pancreatic polypeptide response to a meal is inhibited by truncal vagotomy but returns towards normal with time. We have examined this hypothesis by measuring the pancreatic polypeptide response to a meal in five dogs before and 1 and 6 months after truncal vagotomy. Pancreatic polypeptide responses to food were significantly(More)
Although blood flow and cholinergic tone influence gastric and salivary gland secretion, their role in pancreatic secretion is poorly defined. The purpose of the present study was: (1) to test the hypothesis that an increase in pancreatic blood flow accompanies stimulated pancreatic exocrine secretion, and (2) to examine the effects of cholinergic agents on(More)
Exogenous prostaglandins inhibit visible gastric muscosal lesions produced by both absolute ethanol and cold restraint in the rat. Pretreatment with “mild irritants” significantly reduces the magnitude of ethanol-induced lesions presumably by stimulating endogenous prostanoid production. The effect of mild irritant pretreatment on cold restraint-induced(More)
Inhibition of monoamine oxidase B (MAO B) by selective inhibitors pargyline and l-deprenyl increases dopamine (DA) and norepinephrine (NE) concentrations in nucleus accumbens (NACB) and is associated with reduction in cold water restraint-induced gastric mucosal injury, inhibition of basal gastric acid output, and regional gastric mucosal blood flow.(More)
The present studies were undertaken to evaluate the histologic effects of graft-versus-host disease on the host colon after small bowel transplantation. Graft-versus-host disease was produced in six Lewis × Brown Norway F1 rats by performing vascularized, out-of-continuity small bowel transplants from parental Lewis donors. Host proximal and distal colon(More)
