One of the early events in physiological shock is the generation of activators for leukocytes, endothelial cells, and other cells in the cardiovascular system. The mechanism by which these activators are produced has remained unresolved. We examine here the hypothesis that pancreatic digestive enzymes in the ischemic intestine may be involved in the generation of activators during intestinal is...

Subcutaneous injection of 50 μg octreotide before a meal can almost totally prevent the increase in exocrine pancreatic secretions caused by the meal. Octreotide inhibits plasma amino acid uptake by pancreatic acinar cells, and thus synthesis of pancreatic enzymes. This effect has clinical potential.

The side effects associated with the usage of synthetic antidiabetic drugs make it imperative to search for alternative drugs from medicinal plants. Therefore, this study was aimed at evaluating the α-amylase and α-glucosidase inhibitory potential of Calotropis procera leaf, as well as its possible mode of inhibiting these enzymes. Acetone, aqueous and ethanolic extracts of C. procera leaf was ...

The metabolism of inorganic sulfate in pancreatic acinar cells was studied by electron microscope radioautography in mice injected with sulfate-(35)S. Labeled sulfate was concentrated in the Golgi complex at 10 min. Within 30 min, much of the radioactive material had been transferred to condensing vacuoles. These were subsequently transformed into zymogen granules. By 4 hr after injection, some...

Immunoreactive trypsin concentration and pancreatic lipase activity were measured in the sera of 33 patients with primary biliary cirrhosis. Immunoreactive trypsin was increased (above the normal range) in 16 (48%) and pancreatic lipase activity in 18 (55%) patients. Both enzymes were increased in 10 (30%) patients. Twenty four patients (73%) had an increase of either one or both enzymes. There...

Children with cystic fibrosis have variable degrees of exocrine pancreatic insufficiency which, if untreated, is the main cause of fat malabsorption. The impact of pancreatic enzyme supplementation on fat digestion was measured in 41 children with cystic fibrosis, 11 healthy controls, and five children with mucosal diseases by a non-invasive test of intraluminal lipolysis using 13carbon (13C) l...

There are very few reports of elevated lipase in pediatric inflammatory bowel disease (IBD). Symptoms of pancreatitis may be masked by abdominal pain in pediatric IBD. During the initial presentation of IBD in our patient, lipase was elevated to more than 3 times the upper limit of normal. Normalization of values coincided with remission of IBD. This may be due to extraintestinal involvement of...

Purpose: The transcription factor Forkhead box protein M1 (FOXM1) plays critical roles in cancer development and progression. However, the regulatory role and underlying mechanisms of FOXM1 in cancer metabolism are unknown. In this study, we characterized the regulation of aerobic glycolysis by FOXM1 and its impact on pancreatic cancer metabolism. Experimental Design: The effect of altered expr...
