人胚胎发生过程中磷酸酶的组织化学研究在国外已有不少报导,如古井对人胚胎肠管组织发生过程中的磷酸酶的分布情况的报导。另有些人研究过人胚胎的肾和肢芽发生过程中磷酸酶的分布情况。但国内对人胚胎的组织化学方面的研究报导很少。我们对国人的人胚胎发生过程中小肠的硷性磷酸酶和酸性磷酸酶的分布情况,据不同胎 Histochemical studies of the phosphatase in human embryos have been reported in many foreign countries, such as Furui reported on the distribution of phosphatase during the development of human intestinal tissue. Others have studied the distribution of phosphatases during the development of the human embryonic kidney and limb buds. However, there are few reports on the histochemistry of human embryos in China. We on the process of human embryo in the small intestine of alkaline phosphatase and acid phosphatase distribution, according to different fetal
