铜管取绒毛及直接制备染色体新方法
A COPPER CATHETER FOR CHORIONIC VILLI SAMPLING AND NEW METHODS FOR DIRECT CHROMOSOME PREPARATION
【摘要】 应用铜管绒毛取材器在 B 超下吸取孕早期绒毛10例,盲吸20例,成功27例,成功率均为90%。取绒毛时间以8~9孕周为佳。建立了乙酸解离法和胶原酶消化法直接制备染色体标本,每例标本均获得可分析的分裂相。
【Abstract】 Aspiration of chorionic villi specimen(CVS)was performed with a copper catheterunder real-time ultrasonic visulization in 10 cases,and with the same catheter withoutultrasound help in 20 cases.Twenty-seven CVS were obtained from the 30 cases,a 90%successful rate.The best time for sampling is from the eighth to ninth week of gestation.Two methods of acetic acid dissociation and collagenase digestion were established forthe direct chromosome preparation.Analysable chromosome metaphases were obtained ineach CVS.
