BY R. A. MILLER, B.A., M.D., M.R.C.P.* (From the Royal Infirmary, Edinburgh) Systematic observations on the gastric acidity throughout the first month of life have been undertaken, as no records of its behaviour during that period have been noted in the literature. In order to investigate the acidity, the fasting juice of fifty healthy, mature breast-fed infants was withdrawn from the stomach s...

Because Helicobacter pylori (H pylori) would cause carcinogenesis of the stomach, we need sufficient information for deciding on an appropriate strategy of eradication. Many factors affect the efficacy of eradication including antimicrobial resistance (especially clarithromycin resistance) and CYP2C19 polymorphism. This study was to survey the efficiency of gastric juice for detecting H pylori ...

BACKGROUND AND OBJECTIVES During laparoscopy, the increase of the carbon dioxide tension may increase the synthesis of hydrochloric acid in the parietal cells of the stomach; the source of the secreted hydrogen ions is carbonic acid derived from the hydration of carbon dioxide. The present report tests this hypothesis by correlating the changes of end-tidal PCO2 (ETCO2) with the pH of the gastr...

1. The isolation of a group specific O substance from the gastric juice of human beings belonging to group O is described. Absorbed normal beef serum constitutes the anti-O reagent. 2. The O specific substance inhibits the agglutination of human red blood cells belonging to group O. The agglutination of A cells by the isoagglutinin anti-A, or B cells by the isoagglutinin anti-B, is not influenc...

Material and methods Ten male volunteers without a history of abnormal gastric function, fasted for 10 hr overnight. A nasogastric tube was then passed and the resting juice aspirated. A 200 ml wash of water was instilled down the tube and immediately aspirated to check that the stomach was free of food debris and the tube was in the correct position. Gastric juice was then collected for a peri...

The intrinsic factor content of Berkefeld-filtered human gastric juice has been studied. This appears to vary with the pH at which filtration is carried out and also between individual filters. Significant losses of intrinsic factor may result from filtration and complete loss when filtration is carried out at a low pH. The most suitable pH for filtration appears to be in the range pH 7 to 8.

The international standard ISO 8124-3: 1997 "Safety of toys -Part 3: Migration of certain elements" and "Interim Enforcement Policy for Children's Metal Jewelry Containing Lead- 2/3/2005" by the U.S. Consumer Product Safety Commission (CPSC) to control the amount of eluted lead from metal accessories cannot be simply compared, because the acid extraction methods and the limit values are differe...
