摘要
本文采用图象分析仪对１０例正常足月胎盘不同层次内绒毛进行体视学研究，并对另１０例正常足月胎盘的微绒毛作电镜水平的体视学研究。结果显示底板区和中间区绒毛的多项参数均无显著性差异，故从此两层次内取材所获参数在对照研究中有代表性。电镜测试虽显示底板区与绒毛板区间微绒毛表面积密度及微绒毛腔间表面积密度无显著差异，但由于绒毛板区的绒毛总数等较底板区者显著减少，故可推测此两层次内胎盘的功能不完全相同。并提出了胎盘体视学研究中应注意的事项。
The different horizontal planes of 10 placentas from normal term pregnancy wereexamined by morphometric technic utilizing the automatic image analyser,and the other10 placentas of the normal term pregnancy were provided for investigation at the ultra-structural level to estimate the density of microvillous surface area and intermicrovillous space surface area. The results suggested that the most parameters of villi werenot significantly different between the basal and middle area. At the ultrastructurallevel,there were no significant difference about microvillous surface area density andintermicrovillous surface area density between the subchorionic and the basal area. Thispaper also discussed the sound sampling and measuring practice.
