[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. Acid phosphatase activity was reduced by the second phase of the cycle. In women with habitual abortions the activities of redox enzymes (SDH and alpha-GPDH) reduced as against the controls (p less than 0.05, less than 0.01, less than 0.001), and no ovulatory peak of enzymic activation was detectable. The curves of enzymic activities were in good correlation with rectal temperature curves of the examinees. Elevated enzymic activities during ovulation and in the second phase of a normal cycle evidenced a sufficiently high energy supply of these processes. The detected reduction of leukocytic enzymic activities in women with habitual abortions may be used for the early diagnosis of an unfavorable pregnancy course and, possibly, for the prediction of placental insufficiency.
