Multiplicity of Primates Pepsinogens

Measurement of plasma group I pepsinogens.

Plasma group I pepsinogen (PG I) concentration is now a readily available non-invasive marker of gastric secretory function, with several potentially useful applications. Ninety-eight percent of control subjects had a plasma PG I below 115 ng/ml while values above this level were seen in 43% of duodenal ulcer patients. Plasma PG I levels below the observed normal lower limit of 30 ng/ml were se...

Serum pepsinogens in blood transfusion donors.

The inactivation by carbenoxolone of individual human pepsinogens and pepsins.

1. Carbenoxolone, in suspension at pH 4.0, inhibits swine pepsin A, and human pepsins 1,3 and 5. Human pepsin 5 is the most readily inhibited, and human pepsin 1 the least. 2. Inhibition occurs by a process which is time-dependent, temperature-dependent and proportional to the quantity of carbenoxolone suspended. 3. Carbenoxolone, in solution at pH 7.4 and pH 8.0, inhibits the activation of the...

Serum Pepsinogens in Relation in a Population at High

Concentrations of serum pepsinogens (PG) I and II were determined for 3252 randomly selected adults who participated in a population-based gastroscopic screening in an area of China with one of the world’s highest rates of gastric cancer. PG I and II concentrations in both sexes tended to be higher than reported in other countries, with levels generally higher among males than females. PG I ten...
