作者用兔抗大鼠甲胎蛋白(AFP)血清,对胚胎期、出生、生后和老年大鼠以及新生小鼠脑用PAP免疫组织化学法系统检查主要脏器和神经系统内AFP的分布,发现许多器官组织中有AFP阳性反应细胞,它们的出现和存在各有迟早和久暂之别。除国外巳报道者外,作者还补充口腔上皮、颌下腺和软骨等新资料。对AFP在胚胎期的广泛分布与其生长发育之间的关系作了讨论。 The authors used rabbit anti-rat AFP serum to examine the distribution of AFP in major organs and nervous system by PAP immunohistochemistry in embryonic, neonatal, postnatal and aged rats as well as neonatal mouse brain. Found in many organs and tissues have AFP-positive cells, their presence and presence of each sooner or later do not. In addition to those who have been reported abroad, the author also supplements oral epithelium, submandibular gland and cartilage and other new data. The relationship between the wide distribution of AFP in the embryo and its growth and development was discussed.
