核型

Results The total aberrantion rate of chromosome is 26.7%(23/86);Compared the normal controls,in azoospermic patients,Serum FSH、LH levels increased,The rate of T/LH decreased.and there is a very significant difference(P%26lt;0.05);The resemble results is detected in different outcome in PESA.

结果摘要：86例无精子症患者中异常核型23例，占总例数26.7%；和正常对照组相比较，无精子症组血清FSH、LH升高，T/LH比值下降，差异有显著性(P%26lt；0.05)；PESA能抽吸到精子组比不能抽吸到精子组的FSH、LH偏高，T/LH下降(P%26lt；0.05)。

结果表明，居群内，瘦果扁平度、花瓣长宽比、萼片长宽比变异最为稳定，居群间，这3个繁殖器官的相对性状呈现随着纬度的增加逐渐增大的趋势，并且随纬度的增加，核型不对称系数呈现不断增加而染色体总长不断减小的趋势。

By Giemsa--C technique, the chromosomes of Aegilops tauschii (85A-34) and Hordeum vulgare (H2) and Ae.tauschii- H.vulgare amphidiploid were all produced clear bands, the terminal band, centromeric band, secondary constrition band and rich intercalary bands were displayed distinctly, thus the corresponding Giemsa-C banding patterns were confirmed.
