Studies on Enzyme Action in Digestive Canal I

Studies on Enzyme Action

The hydrolyzing actions of various preparations of the adult eel were studied on ten esters in the usual way. The results are presented in the form of curves for the relative actions and in a table for the absolute actions obtained in one complete experiment. The separation of the enzyme material in some cases into an active portion and a co-enzyme, the mixture showing greater actions on some e...

Studies on the Mechanism of Action of Ru,ey Virus I. Action of Substances Az]~ecting Tiie Reticuloeni)ot]ielial System on Plas~.a Enzyme Levels in Mice

It was recently suggested that the increases in plasma enzyme activity following infection of mice with Riley virus (1) might be due to inhibition of the clearance of enzymes from the blood plasma (2). Preliminary studies confirmed that the plasma clearance of intravenously injected lactate dehydrogenase (LDH) was greatly impaired in Riley virus-infected mice, and also showed that blood clearan...

Digestive Enzyme Supplementation in Gastrointestinal Diseases

BACKGROUND Digestive enzymes are able to break down proteins and carbohydrates and lipids, and their supplementation may play a role in the management of digestive disorders, from lactose intolerance to cystic fibrosis. To date, several formulations of digestive enzymes are available on the market, being different each other in terms of enzyme type, source and origin, and dosage. METHODS This...

Action of secretin on pancreatic enzyme secretion in man. Studies on pure pancreatic juice.

The action of pure, natural secretin on the pancreatic secretion of enzymes was investigated in six patients with external transduodenal drainage of the main pancreatic duct performed after biliary tract surgery. Secretin infused for five successive 50 minute periods at increasing doses of 0.03, 0.1, 0.3, 0.9 and 2.7 clinical units (CU)/kg/h, produce a dose dependent increase in protein and lip...
