用光镜和透射电镜观察了山溪 (Batrachuperuspinchonii)不同发育时期卵母细胞的显微与超微结构 ,特别注意了与卵黄发生相关的细胞器变化。结果表明 ,类核周体为线粒体、高尔基体、内质网等膜性细胞器聚集的场所 ;线粒体自身也可演变成卵黄前颗粒 ,参与构成卵黄小板的成分 ;吞饮泡和髓样小体是卵母细胞利用外源卵黄物质的中间媒介。经过与其他动物卵黄发生过程相比较 ,认为非哺乳脊椎动物卵黄发生是卵母细胞在多种细胞器参与下整体活动的结果 ,不是经由单一的模式或途径形成 ,因此呈现发生上的多元化 ;不同物种在卵黄发生中分别采取与各自相适应的模式或途径。
The microscopic and ultrastructural changes of oocytes at different developmental stages of Batrachuperus pinchonii were observed by light and transmission electron microscopy, with particular attention to the organelle changes associated with the occurrence of yolk. The results showed that the perinuclear bodies were the sites of accumulation of membranous organelles such as mitochondria, Golgi and endoplasmic reticulum. The mitochondria itself could evolve into the former particles of yolk and participate in the composition of yolk platelets. Is the oocyte using exogenous yolk intermediates. After comparing with the process of egg yolk in other animals, it is considered that the non-feeding vertebrate yolk is the result of the oocyte’s overall activity under the participation of many organelles, not formed by a single pattern or pathway, thus presenting the occurrence of diversification; Species in the yolk were taken to adapt to their respective patterns or ways.
