人胎儿骨骼发育与骨髓造血部位的大体观察

GROSS OBSERVATIONS ON THE DEVELOPMENT OF BONE AND THE HEMATOPOIETIC SITES IN HUMAN FOETUS

本文观察了不同胎龄胎儿的身长、部分骨骼的长度及增长速度,胎儿骨髓造血部位发生的时间、顺序及其造血灶特点。认为妊娠早期及中期胎儿生长较快,12周胎儿,较多部位的骨骼已出现造血灶。20周时,全身大部分骨髓参与造血。

We observed the foetal length、bone length and grouth speed of the bone at present paper. The charaetristic of the time、sequaence of the hematopoietic site appearred in different bones were studied.The result showed that the grouth of foetus speeded quickly in early and middle cmbryonic stage.In 12 weeks of foetus, the hematopoietic sites occurred in the part of foetal bone. In 20 weeks, the bone marrow in most of foetal bone had the hemapoiesis.
