Abstract

Acid and alkaline phosphatase activities in the mouse cerebrum, brainstem and cerebellum increased during the late fetal and perinatal period and reached a maximum on postnatal day 28 (P28). Myelination was most extensive on P28-P45 in the brainstem and in the cerebellum, and phosphatidic acid phosphatase activity concomitantly decreased to a low level after birth. The changes in acid and alkaline phosphatase activities correlate more with the extent of myelination than with the overall brain tissue growth.

摘要

在小鼠的大脑、脑干和小脑中,酸性和碱性磷酸酶活性在胎儿后期和围产期增加,并在出生后第28天(P28)达到最大值。髓鞘形成在出生后第28天至45天在脑干和小脑中最为广泛,并且磷脂酸磷酸酶活性在出生后随之降低至低水平。酸性和碱性磷酸酶活性的变化与髓鞘形成的程度相关性更大,而不是与整个脑组织的生长相关。
