摘要： 以微铺展法制备豚鼠精母细胞联会复合体标本，经硝酸银染色后作电镜观察，建立了SC组型。与有丝分裂染色体组型比较，发现二者有良好的一致性。在粗线期，X,Y轴的配对区很短，配对区的X轴和Y轴没有明显变细。未发现银染SC具有着丝粒，并对可能的原因做了分析讨论。Synaptonemal complexes (SC) in Guinea pig (Cavia porcellus) spermatocytes prepared with micro-spreading technique and silver staningwere analyzed by electron microscopy.The meiotic SC karyotype was constructed from 7 cells and compared with the mitotic chromosome karyotype. There is a good agreement between them. At pachytene, there is only a very a very short pairing region in which X-and Y-axis are not stinctly thin.The kinetochore thin. The kinetochore was not found on each SC in our experiments and probable reason has been discussed.
