山西省绒毛染色体研究协作组利用绒毛细胞直接制备染色体标本,可于当日或次日得到结果。本法与其它直接制备法的不同特点在于提前加入秋水仙碱。半年内共完成162例绒毛染色体检查,其中包括20例盲吸绒毛标本的制备。工作分三个阶段: 第1阶段,取人流绒毛12例,实验步骤设多种不
Shanxi villus chromosome research collaboration group using villus cells to directly prepare chromosome specimens, the results can be obtained the same day or the next day. The difference between this method and other direct preparation methods is the addition of colchicine in advance. A total of 162 cases of chromosomal examination of villi were completed within six months, including the preparation of 20 cases of blind suction villus specimens. The work is divided into three stages: the first stage, taking 12 cases of human hair villus, experimental procedures set a variety of no
