摘要
以每毫克绒毛所产生的细胞中期分裂相为指标,比较来自绒毛膜着床点近端、远端和中间部位的绒毛及外观形态不同的绒毛对染色体制备的影响。发现在孕早期经绒毛活检镜采样无关,但含有血管、外观透明度好的绒毛所产生的细胞中期分裂相数则显著高于不含血管的绒毛。
The quantity of metaphase yielded by per mg villus was used as an index. Comparing the effect on chromosome preparation of chorionic villus with different morphology from three position on chorion, we found that there was no significant difference among those regions but the significant increase of metaphase existed in the samples from those villi with blood vessels.
