[Desoxycytydil-deaminase activity in obstetrics].

The Deoxycytidyl-Deaminase activity in the plasma of 75 woman with a normal or complicated pregnancy was estimated. The control group consisted of 20 healthy, non-pregnant woman. Only in the cases of pregnancies with trisymptomic toxaemia and chronic kidney diseases high enzyme activities were estimated. There are no timedependent changes in the enzym activity during a normal pregnancy. The estimation of the enzyme activity of DCMP-Deaminase in the plasma seems to be a valuable method for the registration of pregnant woman with classical EPH-Gestosis and chronic kidney diseases.
