摘要
用常规石蜡切片法研究水牛卵泡在卵巢中的分布规律与结构特征。结果表明:各级卵泡的分布具有明显的区域性;原始卵泡位于卵巢皮质的最外层,形成原始卵泡层,初级卵泡位于皮质的中层,次级卵泡位于富含血管的皮质最内层;原始卵泡、初级卵泡和次级卵泡的直径分别为(36.9±7.7)μm、(48.7±8.9)μm和(91.9±27.3)μm,与之对应卵母细胞的直径分别为(19.6±6.0)μm、(27.3±7.1)μm和(49.1±17.4)μm;原始卵泡和初级卵泡的颗粒细胞数为(10.8±2.3)个和(18.1±3.1)个;次级卵泡含有2~6层颗粒细胞,2~4层的颗粒细胞分布不均。
The distributing and histomorphology of buffalo preantral follicles in ovary was studied by paraffin section. The distributing of different stage follicles had distinctly region. Primordial follicles, which had one layer of squamous granulosa cells, were always located in the outer part of the cortex. Primary follicles, which had a single layer of cubical granulosa cell, were found in the middle cortex. Secondary follicles, which distributed many large blood vessels, had two or more layers of cubical granulosa cells and were distributed only within the inner region of the cortex. Follicles had 2 or 4 layers of granulosa cells, which distributed asymmetricly. The diameter of primordial, primary and secondary follicles was ( 36. 9 ± 7.7 ) μm, (48. 7 ± 8.9 ) μm and ( 91.9 ± 27.3 ) μm respectively and the diameter of corresponding oocytes was( 19.6±6. 0) μm, (27.3 ±7. 1 ) μm and(49. 1 ± 17.4) μm respectively. The number of granulosa cells in primordial and primary follicles were ( 10. 8 ± 2. 3 ) μm and ( 18. 1± 3. 1 ) μm respectively
