ABSORBABLE FUNCTION OF THE GASTRIC INTESTINAL METAPLASIA

Abstract

Regarding absorbative function of gastric intestinal metaplasia, we investigated electronmicroscopically and histochemically the morphological variation of the microvilli using biopsy specimens after giving oleic acid perorally. Electrnmicroscopic findings of the microvilli revealed variation of the microvilli. From the bottom of the gland to the top, the microvilli maturate in morphology. In immature intestinal metaplasia, immature microvilli of which the height is low and its distribution is scarce, recognized in wide portion. After peroral oleic acid load, its uptake was made clear using the biopsy specimens. Oleic acid uptake was recognised widely than in ALP positive area.
