Pancreatic polypeptide: a review of its involvement in neuro-endocrine reflexes, islet-acinar interactions and ethanol-evoked physiopatologic pancreatic gland changes.

prevents, in pancreocytes, the evolving of a "supramaximalecbolic-stimulation" process. The PP involvement as a modulating agent of pancreon's reactivity is reflected by the progressive increment of its plasma values in the first week of an evolving AP episode. In the AP associated to a large meal, an overpowering of the pancreon's brake might have a pivotal role.

Streptozotocin-induced diabetes, bile-pancreatic secretion and insulo-pancreon-axis interaction.

The present tests were undertaken in order to analyze in male Wistar rats the changes in the exocrine and endocrine pancreas and on the interactions that normally evolve in the insulo-pancreon-axis. To evaluate this by a single i.p.

[Biochemical profile of the pancreatic function: pancreolauril and oral glucose tolerance tests].

Background: The pancreas is a mixed gland that takes part in the digestion of nutrients and in the homeostasis ofglycemia. Chronic pancreopathy is the cause of secretory insufficiency, characterized by an inflammatory process that leads to fibrosis of the pancreas, with a progressive loss of both exocrine and endocrine functions of the gland.

Objective: To study both the exocrine and endocrine pancreatic relationship in patients with pancreatopathies and other non-pancreatic digestive alterations, by means of serum pancreolauril (sPL) and oral glucose tolerance tests (OGTT).

Influence of hydrocortisone, prednisolone, and NO association on the evolution of acute pancreatitis.

Leukocyte activation, inflammatory up-regulation, and microcirculatory disruption associated with ischemia-reperfusion injury are hallmarks in the pathogenesis of acute pancreatitis (AP). NO donors ensure microvascular integrity, while glucocorticoids act as anti-inflammatory and immune modulator drugs. AP was induced by the biliopancreatic duct outlet exclusion-closed duodenal loops (BPDOE-CDLs) model.

Relaxin prevents the development of severe acute pancreatitis.

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 hormone that has been attributed vasorelaxant properties via the nitric oxide pathway while behaving as a glucocorticoid receptor agonist.
