[Characteristics of enzyme activity of leukocytes in women with history of habitual abortion].

Leukocytic dehydrogenases (succinate and alpha-glucose phosphate dehydrogenases) and acid and alkaline phosphatase hydrolases activities were cytochemically assayed in 20 healthy women with normal menstrual cycles (controls) and 34 ones with habitual abortions. Ovulation in health was associated with a significant elevation of SDH, alpha-GPDH, and alkaline phosphatase activities. The second peak of enzymic activation, less marked, was recorded on days 20-24 of the cycle.
