[Liver function tests under the influence of sequential treatment using ethinyl estradiol-norethisterone acetate and ethinyl estradiol-chlormadinone acetate].

30 young healthy women were investigated during the first therapy cycle with ethinyl-estradiol-norethisterone acetate and ethinyl-estradiol-chlormadinone acetate as a sequential regime. The following laboratory data were achieved by each of the investigated group of young women: serum aminotransferase (GOT and GPT), serum alkaline phosphatase and alpha-amylase-activity in serum, serum proteins, serum cholesterol, serum bilirubin, serum ZST, serum TTT and the indocyaningreen-clearance of the liver. The serum protein pattern was determined by the paper electrophoretic method. A significant decrease of the aminotransferase GPT was viable during the sequential therapy with ethinyl-estradiol and norethisterone acetate. This viable decrease of the GPT was induced through the application of norethisterone acetate to estrogen. The alkaline phosphatase was significant lightly lower and the beta-globuline lightly elevated at the end of the therapy cycle. The sequential therapy with ethinyl-estradiol and chlormadinone acetate induced only a significant increase of the ZST in serum.
