Chromatographic Patterns of Individual Gastric Juice
ثبت نشده
چکیده
Separation of the large molecular components of pooled human gastric juice into fractions of different biological activity by means of the Amberlite IRC-50 resin column has been reported earlier (1-6). In the present study a modification of this technic has been adapted to the fractionation of individual specimens of gastric juice. These modifications have improved and further standardized the older method.

متن کاملThe pepsins from human gastric mucosal extracts.
1. The pepsins and pepsinogens of the gastric mucosal extracts of two normal subjects, of seven patients with gastric adenocarcinoma and of two patients with duodenal ulcer have been investigated by agar-gel electrophoresis and by ion-exchange chromatography. 2. Of the eight zones of proteolytic activity that have previously been reported in normal human gastric juice, seven can be detected in ...
متن کاملSecretion of intravenously administered antibiotics in gastric juice: implications for management of Helicobacter pylori.
AIMS To study whether differences in eradication rates of antibiotics may be explained by differences in secretion of antibiotics in gastric juice. METHODS A single intravenous dose of either ampicillin 500 mg, erythromycin 500 mg, or metronidazole 500 mg was administered to four healthy Helicobacter pylori negative volunteers on different days. Antibiotic concentrations were measured in gast...
متن کاملHuman Gastrointestinal Juices Intended for Use in In Vitro Digestion Models
The aim of this study was to characterise the individual human gastric and duodenal juices to be used in in vitro model digestion and to examine the storage stability of the enzymes. Gastroduodenal juices were aspirated, and individual variations in enzymatic activities as well as total volumes, pH, bile acids, protein and bilirubin concentrations were recorded. Individual pepsin activity in th...
