Characterization of Human Intestinal Lactase and Hetero-β-Galactosidases of Infants and Adults
TL;DR: Examination of colchicine inhibition revealed considerably less effect on the human lactase than has been reported in the case of the rat enzyme, and no differences in the properties of either intestinal lactase or hetero-d-galactosidases in the three groups of intestine examined.

Postnatal intestinal development
D. Kelly,R. Begbie,T. P. King +2 more
TL;DR: Early postnatal intestinal development involves the preparation of the intestinal epithelium for extrauterine life when maternal secretions provide the sole nutrient source as mentioned in this paper, and a further shift in the digestive capability occurs later in development with the introduction of complex solid foods.

Effect of physiologic concentration of lactose on prevention of postweaning decline of intestinal lactase.

TL;DR: Assay of lactase activity in mucosa from the jejunal and ileal segment in these rats failed to reveal any significant difference in either lactase, sucrase or maltase activity, regardless of whether the activities were expressed in terms of the whole intestine, per gram of intestine, or per 100 g of body weight.
Journal ArticleDOI
Effects of glucose, sucrose, and lactose on intestinal disaccharidases in the rat.
TL;DR: Diets containing 68 per cent glucose, sucrose, or lactose were fed to 40-day-old and adult rats for 1 to 12 weeks, and Dietary effects on the intestinal enzymes were greatest in the middle half of the gut.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.

The digestive function of the epithelium of the small intestine. II. Localization of disaccharide hydrolysis in the isolated brush border portion of intestinal epithelial cells.
David T. Miller,Robert K. Crane +1 more
TL;DR: The epithelial brush border membrane has been isolated as a morphologically distinct entity from homogenates of intestinal mucosa and found to contain virtually all of the invertase and maltase activities of the unfractionated homogenate.

A cytochemical study on the pancreas of the guinea pig. I. Isolation and enzymatic activities of cell fractions.
TL;DR: The incorporation of labelled leucine into the proteins of microsomal subtractions and in those of postmicrosomal fractions was studied comparatively in the pancreas of fasted and fed guinea pigs as well as in the liver and pancrea of fasting animals.
