Morphological changes of the gut as the result of acute hemorrhage

In experiment on rats morphological changes of the gut depending on life expectancy as the result of acute hemorrhage have been studied. During the first day in mucous tunic of the small intestine reduction of its thickness, desquamation and necrosis of villi were marked, in 7,4 % of cases there were erosions and ulcers. The quantity of mast cells with degranulation attributes was increasing from 3 o'clock till 7 o'clock, eosinophilic leukocytes - from 12 o'clock till 24 o'clock. As a result dystrophic changes in ganglion cells of vegetative nervous textures and in smooth muscle cells of a muscle coat led to paresis of the intestine. Changes in the small intestine were characterized by greater expressiveness of dystrophic and necrotic injuries in comparison with the large intestine
