Experimental choriocarcinomas of the rat were studied with electron microscopy and compared with the ultrastructure of rat trophoblasts at mid-and late-gestational stage. The choriocarcinoma numbered m-803 contained abundant cytoplasmic organellae and was quite similar to the trophospongial cell at late-gestational stage. The M-801 closely resembled the trophospongial cell at mid-gestational stage. The m-673, which has 3-beta-ol dehydrogenase enzyme system, could not be studied sufficiently inspite of the examination of more than 30 blocks of epon embedded specimen, because of the degeneration and necrosis occurring in the specimens.
对大鼠实验性绒毛膜癌进行了电子显微镜研究，并与大鼠妊娠中期和晚期滋养层细胞的超微结构进行了比较。编号为m - 803的绒毛膜癌含有丰富的细胞质细胞器，与妊娠晚期的滋养海绵层细胞非常相似。M - 801与妊娠中期的滋养海绵层细胞非常相似。尽管对30多个环氧树脂包埋标本块进行了检查，但由于标本中出现退变和坏死，具有3-β-醇脱氢酶系统的m - 673未能得到充分研究。
