THE COMPOSITION OF INTESTINAL SECRETIONS

The Acid-base Composition of Gastric Secretions

The chief inorganic factors in secretions obtained from isolated pouches constructed in the fundus and in the pyloric antrum of the cat's stomach were found to be chloride ion and fixed base. In a series of samples obtained from the fundic pouch, chloride ion was approximately stationary at 165 cc. 0.1 N per 100 cc. During digestion of food in the stomach, secretions from the pouch contained fi...

The stability of the radiotriolein bond in intestinal secretions.

The radiotriolein test has been reported to be unreliable in the diagnosis of steatorrhoea. A possible explanation is provided by these studies in which labelled triolein was incubated in human gastric juice, duodenal juice, and faeces; the bond was not stable on duodenal juice.

Studies on the quantitation of immunoglobulin in human intestinal secretions.

There is increasing evidence for the importance of the secretory immune system in the gut. In studies of local antibody production it is important to have satisfactory methods for measuring immunoglobulin concentrations and to be aware of the errors which may occur. Studies on immunoglobulin measurement in intestinal secretion by the radial immunodiffusion method are reported, showing the effec...

Composition of the neutral lipids of bovine meilbomian secretions.

Lipids secreted form the bovine meibomian glands were assigned to following classes: cholesteryl esters (A) (fatty acyl chain lengths from 15 to 27 carbon atoms), 41%; wax esters, 29%; triacylglycerols, 10%; and cholesteryl ester (B) (fatty acyl chain lengths from 14 to 18 carbons), 15%. The remaining 5% consisted of cholesterol, fatty acids, and highly polar material. Analysis of the lipids sh...
