Summary

In investigating the activity of the alkaline and acid phosphatases in the uterine and placental tissues on the 6th, 10th, 15th, 17th and 18th day of pregnancy certain regular cytochemical features are revealed.

Phosphatases are localized mainly in the nucleoli, nucleus and then in the cellular cytoplasm. Large amounts of alkaline and acid phosphatases are found in the leukocytes of the maternal blood and in the embryoblasts. Alka-line phosphatase appears in the uterus at the onset of pregnancy and gradually increases until its termination. Acid phosphatase appears only on the 10th day and greatly increases until the end of the pregnancy.

The largest amounts of phosphatase are revealed in the trophoblastic syncytium which covers the fetal blood vessels and lies next to the lacunae filled with matemal blood.
