[Enzyme activity and ultrastructure of the intestinal epithelium in mice treated with rifampicin].

Some enzymatic activities and the ultrastructure of the intestinal epithelium of mouse were valued after a treatment with rifampicin, per os, in different doses (25 mg/Kg and 50 mg/Kg), for 90 days. Neither alteration of maltase, lactase, leucine aminopeptidase (LAP), nor modification of the morphology of jejunal mucous membrane enterocytes and of their mitochondria were noticed in treated animals, as to controls.
