Both vagus nerves and the celiac ganglion complex are the main source of the pancreatic gland innervation. In both man and dog there is a distinct difference in the number of fibers ending in the different segments of the gland. In the former, the macroscopic innervation is primarily concentrated in the pancreas head and isthmus. In the latter most of the(More)
AIM To investigate the severity of acute pancreatitis (AP) is associated to the intensity of leukocyte activation, inflammatory up-regulation and microcirculatory disruption associated to ischemia-reperfusion injury. Microvascular integrity and inhibition of pro-inflammatory mediators are key-factors in the evolution of AP. Relaxin is an insulin-like(More)
BACKGROUND AND AIMS In the general adaptation syndrome, gastric lesions are the first manifestation of stress. We hypothesized that acute pancreatitis (AP), an inflammatory acute disease, will be exacerbated if unchained following stress. Visceral hypersensitivity will be enhanced due to catecholaminergic discharges leading to an over-induction of the(More)
The secretory effect elicited by the ingestion of 100 ml of orange-lemon juice (O.-L.J.) was studied on pure pancreatic juice obtained from a catheter placed in the human Wirsung duct at surgery. These changes were compared with those evoked by a regular meal (R.M.), the ingestion of a Sorbitol solution (S.S.), the intragastric infusion of an acidified(More)
CONCLUSION This study demonstrated that LPS infusion can induce tissue lesions and impair the exocrine protein secretion of the pancreas in rats. BACKGROUND The effect of chronic ip infusion of lipopolysaccharide (LPS) on the exocrine pancreas function was studies in rats. METHODS Four milligrams per kilogram per day of Salmonella typhi LPS were infused(More)
The secretory response of the exocrine pancreas to an intravenous bolus of secretin (1.0 U/kg) was studied in healthy men and women below and above 45 years of age. We studied the secretory pattern, i.e., electrolyte and enzyme secretion in 8 sequential, 10-min collections and cumulative values for each parameter. Within the male group, no significant(More)
