[Incidence of toxic liver lesions due to Gravistat].

In 200 women who on the average 5.6 years took ovosiston and/or non-ovlon, and in 40 women who during the last three months had not taken an oral contraceptive we determined the GOT, the GPT, and LP-X and the cholesterol in the serum before and after a three weeks intake of gravistat. After a three weeks intake of gravistat of the two groups ca. one fourth showed pathological transaminases. 30 women with pathological transaminases and/or positive LP-X were hepatologically investigated including liver biopsy after an on an average 7.3 weeks exposition of gravistat. In ca. one third of the cases histologically provable changes of the liver (toxic hepatosis, fatty liver, infectious hepatitis) and in ca. two thirds of the cases the picture of the metabolic activation were found. Morphologically no signs of an intrahepatic cholostasis could be proved, so that it does not seem to be the leading parameter of the toxic liver damage.
