Result:The best prescription was : Lecithin: Sodium Cholate =8∶1,Lecithin:Proanthocyanidins =15∶1,sonde-type ultrasound time was 5 min,the entrapment efficiency of FNL was 67.13%,and the results revealed the FNLs were sphere like with the mean size of 168.3 nm,the mean Zeta potential was –86.6 mV.

结果：最佳处方和制备工艺条件为卵磷脂与胆酸钠的质量比为8∶1、卵磷脂与原花青素的质量比为15∶1、探头式超声5 min。包封率为67.13%，所得柔性纳米脂质体为类球形实体粒子，平均粒径168.3 nm，平均Zeta电位-86.6 mV。

The results show that the CD29, CD49, CD90 express in the gonium and the primary spermatogenous, but there are not expression in the oocyte, the second spermatogenous and the spermatocyte.

研究结果表明，CD29， CD49， CD90在雌性生殖腺各级卵母细胞中均不表达，位于生殖褶边缘的性原细胞中可见表达；在雄性生殖腺的初级精原细胞中表达，但在成团分布的次级精原细胞、各级精母细胞中均未表达。

At the small growth stage, three kinds of the sex steroid receptors usually were localized in the cytoplasm or nuclear membrane of oogonia and early primary oocyte, and localized in the cytoplasm and nucleoplasm of oocytes at the large growth stage and mature stage.

在小生长期，3种受体通常定位在卵原细胞和早期初级卵母细胞的胞质或核膜；在大生长期和成熟期，则定位在胞质和核质。

All chickens were orally challenged with homologous sporulated oocysts at 26 days of age and killed at eight days post challenge. Weight gains, anticoccidial index and oocyst output were determined and compared with those of the control animals.

以可溶性的GST-gam56-2融合蛋白为免疫原，设立高、中、低(1.0 mg、0.5 mg、0.25 mg) 3个剂量，单独或使用弗氏完全佐剂，于5 d、12 d和19 d对雏鸡进行3次免疫， 26 d用5×104个E.maxima孢子化卵囊进行攻虫，8 d后迫杀，对各组的存活率、相对增重率、卵囊减少率、ACI等指标进行统计分析。

The regression analysis shows that the development of the oogonium is accelerated at low temperature and longer daylength (from Dec. to Mar.).

回归分析显示，低温和延长的日照时间（12~3月）促进卵原细胞增殖；高温和长日照（4~6月）促进卵母细胞生长。

To eplore the relationship between Dynein and the formation of meiosis error of oocytes, the immature mouse oocytes were in vitro cultured with a known dynein ATPase activity inhibitor- sodium orthovanadate to detect the changes of maturation rate, and semi-quantitative RT-PCR and single cell RT-PCR were performed to detect the alteration of the cyclin B1 mRNA level.

为探讨Dynein与卵母细胞减数分裂错误形成的关系，采用小鼠卵母细胞体外培养成熟技术和半定量RT-PCR方法，分别检测Dynein抑制剂-原钒酸钠对卵母细胞成熟率和cyclin B1基因转录水平的影响。

The results indicated: 1 .There is obvious difference between the gonads of precocious and unprecocious fish: in female, the ovaries of unprecocious fish stay in 141 stage, and are mainly consisted of oogonias and early oocytes; the ovaries of precocious fish have developed into IIIAV stage, most of the oocytes are in the large growth stage.

性早熟与未早熟大黄鱼性腺的发育有显著不同：未早熟鱼卵巢停留在Ⅰ～Ⅱ期，卵巢内主要由卵原细胞和早期卵母细胞所组成；性早熟大黄鱼卵巢已发育至Ⅲ～Ⅳ，卵巢内大多数卵母细胞处于大生长期中期或后期。

The results indicated that the receptors of estrogen, androgen and progestogen existed in oogonia and oocytes of different developmental stages.

结果表明，不同发育时期的卵原细胞和卵母细胞中都存在雌激素、雄激素和孕激素受体。

The results showed that immunopositive substance existed in the ovary and testis of different stages. At the early developmental stage of ovary, the cytoplasm and nucleolar membrane of oogonia and early primary oocyte showed immunopositive reaction with strong or medium intensity to 17 b -estradiol, testosterone and progesterone antibodies.

在卵巢发育早期，卵原细胞和卵母细胞的胞质和核仁膜对雌二醇、睾酮和孕酮抗体显示强或中等强度免疫阳性反应；在大生长期和成熟期，卵母细胞胞质和核仁膜对睾酮和孕酮抗体的免疫阳性反应明显减弱，而对雌二醇则显著增强。

The results showed that Golgi complex was an organelle that experienced a series of changes during four stages of the oogenesis of Bullacta exarata , which were oogonia, early vitellogenic oocyte, mid-vitellogenic oocyte and end vitellogenic oocyte.

结果表明，在泥螺卵子发生的四个时期即卵原细胞期、卵黄发生早期、卵黄发生中期和卵黄发生后期，卵母细胞内高尔基复合体经历了一系列的变化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
