Abstract:
:The morphology of the rat duodenum after chronic treatment with 15% (v/v) ethanol and 4% (v/v) pentanol was studied. Male Wistar rats of experimental groups were given ethanol and pentanol for 15 weeks with food and fluid freely available. Ethanol-15% and 4% pentanol-fed rats showed a significantly reduced fluid and food intake as compared with control rats. The study of the mucosa indicated that the number of chronic inflammatory infiltrating (mononuclear cells) and goblet cells was higher in the groups of the ethanol- and pentanol-fed rats than in the control group. There was an increase in the thickness of the brush border in pentanol-fed rats. Intervillus adhesion was concurrently observed in the pentanol-fed rats but not in the control or ethanol-fed rats. After ethanol feeding many of the villi developed blebs at the apex of the villus or laterally on its upper half. These blebs generally remained intact. In contrast, after pentanol feeding no bleb formation was appreciated. The intake of ethanol and other short chain alcohols present in alcoholic beverages leads to mainfold disturbances on the rat duodenum. These findings suggest that the chronic ingestion of pentanol seems to promote cellular changes but less important than those observed after chronic ethanol ingestion.
