[Enzymomorphology in cholerogenic intoxication in suckling rabbits].

The cholerogenic effect produced in suckling rabbits by intraintestinal administration of a cholerogen was shown to be accompanied by the edema of villi, formation of lympho-histiocytic infiltrates in the stroma and bases of crypts, hemorrhages in the stroma of the villi and loss of individual enterocytes mostly on tops of the villi. In the large intestine, vacuolation and pyknosis of the epithelial nuclei and edema of the submucosa were observed. The intensity of the cholerogenic effect correlated with the degree of the decline of the activity of succinate dehydrogenase, adenosine triphosphatase, alkaline and acid phosphatases in the intestinal tract. Intraintestinal administration of heat-inactivated cholerogen induced no cholerogenic effect and the enzymatic activity in the intestinal tract declined focally and insignificantly.
