摘要：

Alkaline phosphatase activity was measured in whole ovarian homogenates from prepubertal mice of different ages, with and without prior injection of human chorionic gonadotropin. Alkaline phosphatase activity was also scored in the different cell types in sections of similar ovaries, using 2 distinct histochemical procedures. The results from those methods differed. Biochemical studies indicated the presence of 3 distinct alkaline phosphatase activities: I and Ib, both optimal at pH 10.4 and with similar substrate requirements and inhibitor sensitivities (phosphatase I being characteristic of unstimulated ovaries and Ib of ovaries stimulated with human luteinizing hormone or human chorionic gonadotropin), and phosphatase II, optimal at pH 9.4, with different substrate requirements and inhibitor sensitivities. The differences observed using the histochemical procedures can probably be accounted for by the effects of different incubation conditions on the activities of these 3 enzymes.
