【摘要】 :根据牛离体卵巢黄体的不同状况 ,将 31枚卵巢分为 5种类型 ,并采用机械方法分离腔前卵泡 ,观察不同黄体状况卵巢与腔前卵泡采集数量的关系。结果表明 ,火山口型、圆锥型和蘑菇型 3种大黄体的卵巢腔前卵泡采集量多 ;扁平片状和表面无黄体型卵巢腔前卵泡采集量较少。具有黄体状况的卵巢初级卵泡 ( Pm)采集数量多于无黄体类型卵巢 ;原始卵泡 ( Pf)以 3种黄体较大的卵巢采集数量最多 ;次级卵泡 ( Sc)则以黄体为火山口型卵巢为最多。说明卵巢黄体状况不同 ,其腔前卵泡采集数量有所不同。更多还原

【Abstract】 Total 31 bovine ovaries from slaughter house were classified as 5 patterns in shape.The preantral follicles were isolated by a mechanical method from them.Then,situation of the ovarian corpus luteum and the numbers of their preantral follicles were observed.According to the analysis of their relationship,the results could be shown as follows:The numbers of preantral follicles collected from the ovaries with the volcanic hole-shaped,cone-shaped and mushroom-shaped corpus luteum,were much more than those collected from the ovaries with flat or without corpus luteum.The primary follicles(Pm) collected from the ovaries with corpus luteum were more than those collected from the ovaries without corpus luteum.The most primordial follicles(Pf) were more in those three shaped ovaries with obvious corpus luteum,but the most secondary follicles(Sc) were more in the volcanic hole-shaped ones.更多还原
