Gastric juice definition

Regardless of terminology, pectin qualifies as fiber under these definitions. Kertesz (52) showed that human saliva, gastric juices, trypsin, and pepsin were ineffective in hydrolyzing pectin. Werch and Ivy (53) demonstrated that pectin passes relatively unchanged through the stomach and ileum. 

Although these findings may apply to an experimental cortisone ulcer in animals, Hitzelberg in our laboratory obtained less definite results in man (H22, H23). Fifteen arthritic patients received 1 g prednisolone in 6 weeks. In the course of treatment, there was never an indication of peptic ulcer formation, although the output and concentration of pepsin in the basal secretion increased on the average about 2-fold. Paper electrophoresis of the dialyzed and lyophilized gastric juice, following steroid administration, frequently showed decrease of total carbohydrate... 

Residual activity of purified HGL or HGL in gastric juice has been tested after the enzyme was incubated for 2 h at various pH values (Ville et al., 2002). In between pH 2 and 6-7, HGL remains highly stable in gastric juice with a recovery of h-pase activity as high as 93%. For extreme pH values, the activity decreases rapidly (pH 8) or is definitely lost (pH 0.5, 0.75 and 1) which means that basal HGL secreted in fhe fasting state is most likely inactivated and that the buffering effect of a meal seems compulsory to preserve HGL activity. Pure HGL is more pH-sensi-... 

Influence of Feeding on the Quantity and the Composition of the Gastric Juice Secreted. — First of all, it has been established that there exists a very definite relation between the secretorial functions and the food absorbed. Thus Chigin, by measuring the quantity of gastric juice which flows after the ingestion of various foods, has found ...
