Objective To assess the food safety of the squid nucleoprotein derived from squid spermary as natural functional composition in health food.

目的对海洋软体动物鱿鱼精巢组织鱼精核蛋白提取物进行食用安全性评价。

In the last EXP, the testis development during the first mature and the ultrastructure of spermatocytes of were studied. The process of spermatid formation was described.

试验四研究了泰山螭霖鱼精巢在第一次性成熟过程中的发育规律和各级精母细胞的超微结构。

The recover stage of testis development showed strong immunopositive reaction to aromatase antibodies, especially in spermatogonia and spermatocyte.

上述研究结果说明，睾酮、雌二醇及芳香化酶参与了大泷六线鱼精巢发育和繁殖内分泌功能调节。

Finally, the physiological function of non-productive sertoli cell and leydig cell during spermatogenesis are discussed in this paper.

最后，文中还讨论了半滑舌鳎精巢中非生殖细胞（间质细胞和Sertoli细胞）的分布及其可能的生理作用。

The females incubated at 33 , their ovarium has powerful cortex, the germinal epithlium produce oocyte, its medulla degenerate into ovarian cavity. During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of ovary increase in quantity, they disintegrate after sexual differentiation. There are a lot of big grana in cells of ovary before sexual differentiation, in the course of sexual differentiation the quantity of the big grana decrease, while small grana increase and peakafter sexual differentiation. The males incubation at 26 , cortices of their testes degenerate into a thin albuginea. Medulla are formed by testicular cords in which scatter spermatogonium.

33℃下孵化的小龟卵巢皮质发达，由原始生殖细胞产生卵原细胞，髓质退化成为卵巢腔，分化时卵巢细胞的超微结构显示线粒体和内质网的数量大大增加，它们在分化结束后解体，分化前细胞内有较多的大颗粒，在分化中大颗粒减少，小颗粒增多，在分化后小颗粒达到最多。26℃下孵化的小龟精巢皮质退化成为一层薄的白膜，髓质有许多睾丸管构成，管腔内有散落排列的精原细胞。

Besides, terminal synapsis was observed to occur in the meiosis of spermatocytes based on the analysis of signal distribution of 5S rDNA on chromosomes obtained from testis.3. 18S rDNA and histone gene h3 were mapped to the chromosomes of C.

此外，通过对5S rDNA在精巢染色体上信号分布特征的观察，认为中国明对虾的同源染色体在第一次减数分裂中期可能发生了末端联会。3。

A strong positive distribution of T and AR was observed in spermatids in stage Ⅱ.

在不同时期的精巢中，T和AR在生精细胞的定位具有一致性。

There is growing evidence that estrogens play important roles in both normal and xenoestrogen disrupted testis physiology.

越来越多的证据表明雌激素在正常的以及雌激素诱导的精巢生理中具有重要的作用。

Myrothecium sp.(Strain NO. Z16) was a marine fungus isolated from the spermary of Argyrosomus argentatus.

Z16是从白姑鱼精巢中分离得到的黑粘座孢霉属Myrothecium sp。

This indicates that CaHIRA plays a definitive role in the development of ovary or oogenesis. In coloreded crucian carp, Cahira gene was expressed in the unfertilized eggs. However its expression decreased dramatically after fertilization. The expression increased again and kept stable from gastrulation till hatching.

成鱼组织中，Cahira在卵巢、脑、心、肝、脾、肾中均有表达，在卵巢和肝脏中表达较强，而在精巢和肌肉中不表达，表明它可能在卵巢发育和卵子发生过程中发挥一定作用。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
