[Alkaline phosphatase in the leukocytes of pregnant women with pre-eclampsia].

The authors studied 74 pregnant women with preeclampsia presenting various degrees of gravity. The activity of alkaline phosphatase was determined cytochemically in the leucocytes. It was established that the activity of the enzyme was unchanged in mild preeclampsia and diminished progressively with advancement of the pathological process, compared with the respective values of normally progressing pregnancy at the same gestational period. A cytochemical criterium is proposed for differentiating the mild form of preeclampsia form the moderate form of preeclampsia.
