| 摘 要： | 多年来,许多生物学家采用压片法(Ohno等,1961,1962;Baker 1963),空气干燥法(Luciani等,1974;Vebele-Kaelhardt,1978;Speed,1985))连续切片的电镜观察(Baker和Franchi,1967)等相继对人卵母细胞染色体进行过研究。Hart-ung等(1978)曾经以~3H-尿嘧啶核苷标记人卵母细胞前期核,观察了RNA的进行性变化。近年来,银染法的广泛运用,不仅揭示了动物,而且还揭示了人的卵母细胞前期核

| Abstract: | The chromoeomes and nucleoli, micronucleoli in prophase of oocytes from human fcotal were studied by Giemsa and silver-staining.There arc profound changes of epiralization, despiralization, respiralization, redespiralization in the chromosomal morphology from preleptotene, diplotene, to dictyotone. The bivalents are uncoiled, extremely extended in dictyotene stage, and morphologically they arc "lampbrush-like".The morphology and number of primary nucleoli, micronucleoli. as well as silver-tained small clots in various stages of prophase are also described. |
