El páncreas es una glándula mixta compuesta por 2 tipos de tejido, endocrino y exocrino, que se agrupan formando lóbulos macroscópicamente visibles y separados entre sí por septos de tejido conjuntivo que contienen vasos sanguíneos, linfáticos y nervios. En humanos, aproximadamente un 80-85% del volumen pancreático está compuesto por la porción principal de tejido que es de naturaleza exocrina, un 10-15% corresponde a la matriz extracelular y los vasos, mientras que la porción endocrina… Expand
Enfermedad inflamatoria del páncreas por autoagresión enzimática: un modelo excepcional de «crinofagia» glandular
La enfermedad inflamatoria del pancreas es revisa, realizando un analisis separado de sus formas clasicas de presentacion: las pancreatitis aguda (PA) y cronica (PC). Expand
Caracteristicas generales de la insuficiencia pancreatica exocrina en caninos
This is a bibliographic review work that aims to know the generalities, diagnostic options and current treatment techniques of IPE in canines. Expand
Paciente femenina de 13 años con diagnóstico de pancreatitis aguda necrotizante y tumor de Frantz
Acute pancreatitis (AP) is a pathological entity that represents an inflammatory condition of the pancreas which can lead to local injury, systemic inflammatory response syndrome, and organ failure.Expand
Trypsin gene expression in adults and larvae of tropical gar Atractosteus tropicus
The results showed that the highest relative try expression occurred mainly in the esophagus, liver, stomach, and pancreas of both wild and captive adult fish; however, captive organisms had a higher try expression level than wild fish. Expand
A review on health benefits of kombucha nutritional compounds and metabolites
This review focuses on recent findings regarding beneficial effects of kombucha and discusses its chemical compounds, as well as the metabolites resulted by the fermentation process. Expand


The Ileum and Carbohydrate‐Mediated Feedback Regulation of Postprandial Pancreaticobiliary Secretion in Normal Humans
Postprandially carbohydrate in the ileum induces changes of upper-gut function that should increase digestion and absorption of carbohydrate since gastric emptying (and delivery of carbohydrate to the duodenum) slows and pancreatic amylase secretion increases relative to trypsin secretion and gastric emptied. Expand
New insights into neurohormonal regulation of pancreatic secretion.
Structural and functional evidence suggests that CCK acts on vagal afferent fibers, which may explain how CCK doses that produce physiologic plasma CCK levels act via vagal cholinergic pathways to stimulate pancreatic secretion. Expand
Do bile acids exert a negative feedback control of cholecystokinin release?
It is concluded that intraduodenal bile is an important modulator of the postprandial secretory activity of the CCK cell. Expand
Regulation of cholecystokinin secretion by intraluminal releasing factors.

The physiological observations that have led to the chemical characterization of the CCK-releasing factors are discussed and the potential implications of this work to other hormones of the gastrointestinal tract are discussed. Expand
Are diets associated with different rates of human interdigestive and postprandial pancreatic enzyme secretion?
It is concluded that diets containing a high proportion of calories as carbohydrate for 2 weeks are associated with lower interdigestive and postprandial pancreatic secretion than diets that have a high fat content. Expand
Expression and distribution of the Na+-[Formula: see text] cotransporter in human pancreas.
Observations suggest that secretion of secretion by human pancreatic duct cells involves the basolateral uptake of Na+ and Na+ via NBC, an electrogenic Na+-[Formula: see text]cotransporter. Expand
Pancreatic ductal bicarbonate secretion: past, present and future.
A HCO(3)(-)-rich secretion may arise as a result of the lack of competition from intracellular Cl(-) for efflux via the anion conductances at the luminal membrane through the cystic fibrosis transmembrane conductance regulator (CFTR) channels. Expand
Adaptation of the exocrine pancreas to diet.

The evidence supports a pretranslational mechanism of the adaptation of proteases, amylase, and lipase to their respective substrates and suggests potential translational mechanisms of other enzymes in these adaptations and suggests the possibility of multiple mechanisms of regulation by a single effector. Expand
Expression and distribution of the Na(+)-HCO(-)(3) cotransporter in human pancreas.
The observations suggest that secretion of HCO(-)(3) by human pancreatic duct cells involves the basolateral uptake of Na(+) and HCO(+) via NBC, an electrogenic Na(+)-HCO(-3) cotransporter. Expand
Intracellular signaling mechanisms activated by cholecystokinin-regulating synthesis and secretion of digestive enzymes in pancreatic acinar cells.
  • J. Williams
  • Biology, Medicine
  • Annual review of physiology
  • 2001
The intracellular signaling mechanisms by which cholecystokinin (CCK) and other secretagogues regulate pancreatic acinar function are more complex than originally realized. CCK couples throughExpand
