[Histological and histoenzymological study of liver. I: In gallstone without treatment (author's transl)].

46 liver biopsies from gallstones and a control group have been studied by histological and histoenzymological technics. The most frequent injuries are in the portal tract, inflammatory infiltration and fibrosis; the most peculiar is a sinusoidal congestion. A brown pigment overload is seen in numerous livers. Lactic-, glyceric-, glutamic-, isocitric-, glucose-6-phosphate-deshydrogenase activities decrease but alkaline phosphatases-, transaminases activities are increased.
