The Duodenal Contents of Infants in Health, and During and Following Diarrhea

Bacterial microflora of the upper gastrointestinal tract in infants without diarrhoea

“…The small intestinal microflora has rarely been studied in normal infants and children (Davison, 1925;Barbero et al, 1952; Anderson and Langford, 1958). The improvement of techniques for obtaining small intestinal juice by intubation (Rhea and Kilby, 1970) and the improvement of anaerobic culture methods (Drasar, 1967) justifies reexamination of the subject, and a qualitative and quantitative study of the aerobic and anaerobic microflora of the upper gastrointestinal tract in a group of 13 infants has been done.…”

Serum Protein Pattern in Infants with Nutritional Disorders

“…All authorities agree that enzyme secretion is depressed in severe protein malnutrition (Veghelyi, 1948;Thompson and Trowell, 1952;Dean and Schwartz, 1954;Gomez, Galvan, Cravioto and Frenk, 1954;Mukherjee and Werner, 1954;Scrimshaw, Behar, Perez and Viteri, 1955). From reports dealing with infants with other conditions it appears that pancreatic enzymatic activity is often depressed in acute and chronic diarrhoea and sometimes during respiratory infections.…”

“…From reports dealing with infants with other conditions it appears that pancreatic enzymatic activity is often depressed in acute and chronic diarrhoea and sometimes during respiratory infections. This depression is often selective, one enzyme being present in normal amounts whilst the other two show lowered values or are absent (Hess, 1913;Davison, 1925;Farber, Schwachman and Maddock, 1943;McDougall, 1950). This demonstrates the need to examine the activity of all three pancreatic enzymes in the duodenal juice in suspicious cases and not to rely merely on a trypsin estimation as is the procedure in many centres.…”

A Study of Gastric Acidity in Infants

“…[3][4][5] for the artificially fed, indicate much higher acidities than those recorded by other writers. Da.vidsohn (3), Mlarriott (7), and Kronenberg(5) give figures, ranging from pl 3 75 to 5-0 for normal infants up to 7 months, which would correspond to lower average acidities.…”
