Mutagenic activity of gastric juice

Cancer Letters, 1979
Gastric juice samples from patients of a rural area of the Colombian Andes at high risk to gastric cancer were tested for mutagenesis with Salmonella typhimurium strains TA100 and TA1538. Direct mutagenic effect was found in samples with detectable amounts of nitrite. This effect was not accountable by nitrite alone.

Stability of metallothionein in gastric juice

Toxicology, 1986
Metallothionein (MT), is presumably the major Cd-binding component of human food. It is not or only partially destroyed by cooking. To study whether MT is stable in gastric juice MT was incubated at various pH values with pepsin and human gastric juice in vitro.

Origin of gastrin in gastric juice

The American Journal of Surgery, 1974
Abstract Four dogs were prepared with an isolated, innervated antral pouch, a Heidenhain pouch, and a gastric fistula. Gastric secretion was stimulated by perfusion of the antrum with a suspension of liver powder or by betazole injection. Both methods of gastric stimulation increased acid and gastrin output from the gastric fistulas and Heidenhain ...

The mutagenic activity of gastric juice

Mutation Research/Genetic Toxicology, 1988
The mutagenic activity of fasting gastric juice was assessed in 123 patients including 18 with normal endoscopic findings, 53 peptic ulceration, 9 gastric cancer, 12 pernicious anaemia and 31 patients who had undergone peptic ulcer surgery in the past. Significant mutagenic activity was detected in 96 (78%). Marked variations in mutagenic activity were

Lactic Acid in Gastric Juice

Scandinavian Journal of Gastroenterology, 1971
The conventional stimulants of gastric secretion (histamine, pentagastrin, and insulin) results in a fall in lactic acid concentration and usually a rise in lactic acid output. Agents that impose indirectly or directly a lactic acid load (glucose, fructose, xylitol, epinephrine) usually result in an increase in lactic acid concentration and output.

Immunoelectrophoresis of human gastric juice

Clinica Chimica Acta, 1963
Abstract Rabbits were immunised with gastric juice depepsinised by making alkaline in vitro and with saliva. Both the resulting antisera and commercial horse anti-human serum antiserum were used to produce immunoelectrophoretic patterns of gastric juice.

The acidity of the gastric juice

The American Journal of Surgery, 1929
Abstract Data concerning the activity of the “mucoid cells” of the gastric glands were considered, and the possible influence of their secretion on the acidity of the gastric juice was discussed.

"GASTRIC JUICE AS A GERMICIDE"

JAMA: The Journal of the American Medical Association, 1925
To the Editor: —InThe Journal, July 25, page 273, appears an editorial comment discussing how bacteria enter the intestinal tract in spite of the germicidal action of the gastric juice. Is it not usually assumed that the new-born baby's intestinal tract is sterile, but that within a few hours after birth the tract is well populated with bacteria?
