Effect of tonicity on glucose absorption and histomorphology of rat intestinal mucosa. 1979

V Mehta, and S I Singh

Perfusion of the gut lumen with 2 ml of isotonic solutions showed uniform absorption of glucose and water over the four 15-minutes study periods, the absorption being maximum in jejunum and least in colon. With hypertonic solutions the glucose absorption decrease was related to the increasing osmolarity and duration of exposure to the solution as well as the nature of the substance used. Histological changes reflecting impaired functions were localised to the tips of the villi and were observed on exposure to hypertonic solution for 45 minutes or more.

D007408	Intestinal Absorption	Uptake of substances through the lining of the INTESTINES.	Absorption, Intestinal
D007413	Intestinal Mucosa	Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.
