The PGCs of Varicorhinus macrolepis first appeared in the mesoderm of early gustrula and subsequently remained in the hypoblast of the embryonic region during late gustrula and neurula stage. At the stage of muscular effect they were found in the splanchnic mesoderm and the proceeded around the gut to the dorsal mestery during hatching stage.

结果表明：泰山螭霖鱼PGCs最早出现于原肠早期；原肠晚期和神经胚期靠近卵黄囊的内胚层；肌肉效应器迁移到脏壁中胚层的肾原基附近；临出膜期到达体腔壁，随后，沿肠系膜进入两侧的生殖嵴中。

According to the size and shape of oocyte, the morphology of nucleolus, the growth of yolk and the structure of follicle, oogenesis of H. d. supertexta can be divided into three stages as follows: oogonium, previtellogenic oocyte and vitellogenic oocyte. The ovary wall is composed of tunica adventitia and germinal epithelium which will produce oogonia and follicle cells. The follicle is the structure unit of ovary.

根据卵细胞的大小、形状，核仁的形态，卵黄颗粒的积累情况，滤泡的结构等，将九孔鲍卵子的发生分为卵原细胞、卵黄发生前的卵母细胞和卵黄发生期的卵母细胞3个时期；卵巢壁由外膜及内生殖上皮构成，生殖上皮分化产生卵原细胞和滤泡细胞；卵巢的结构单位是滤泡。

There was a center zone of dense yolk substance in the zygote, and fingerlike yolk column were given off from the center zone, and varying size yolk granules filled in the yolk column.

受精卵有致密的中心区，由此向周围发散出呈指状突起的卵黄柱，卵黄柱内充满大小不等的卵黄颗粒。

A corresponding portion of the egg of other animals, consisting of protein and fat which serve as the primary source of nourishment for the early embryo and protoplasmic substances from which the embryo develops.

卵黄其它动物蛋内的相应部分，由蛋白质和脂肪组成，用作早期胚胎的主要营养来源和胚胎由此发育的原生物质主要实施生物质气化集中供气系统工程和大型沼气能环工程。

On the basis of purification and immunity of vitellin, antibodies of vitellin were obtained and used to measure the concentration of vitellin in embryo in different stages of embryonic development by enzyme-linked immunosorbent assay.

在采用纯化的卵黄磷蛋白免疫兔子而获得其抗体的基础上，运用酶联免疫吸附检测法(enZyme一linked ilnlnunosorbent assay，ELISA)分析测定了发育过程中胚胎内卵黄磷蛋白的含量。

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。

There was no typical Golgi complex in oogonia, but there were some Golgi vesicles. At the early stage of vitellogenesis, Golgi complex was abundant whose saccules increased to more than ten layers. At the middle stage of vitellogenesis, Golgi complex grew more in numbers and got together, so its secreting quickened. Moreover, it formed a number of Golgi vesicles, which were filled with granule substances that changed into yolk granule finally.

卵原细胞内无典型的高尔基复合体，但具高尔基囊泡；卵黄发生早期，高尔基复合体发达，膜囊数达10多层；卵黄发生中期，高尔基复合体分泌活动加快，产生大量的大小囊泡，囊泡内充满颗粒状物质，最后演变成卵黄颗粒。

Stage I of both male and female stone flounder appears only once in all its life, and the germ cells are comprised by spermatogonia or oogonia. The gonad from Mar to Aug keeps at stage II. The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.

在每年的3月-8月期间性腺处于Ⅱ期，此期精巢中精原细胞明显增多，胞质局部可见有线状的生殖质存在，平均成熟系数为0.037％；卵巢中以2时相卵母细胞为主，可见细胞质中出现强嗜碱性的卵黄核，细胞外由一层滤泡细胞包围，但尚无放射带，平均成熟系数为1.95％。9月-10月期间性腺处于Ⅲ期，此期精巢中仍有大量精原细胞，同时可见部分精母细胞，平均成熟系数为0.086％；卵巢中以3时石鲜孟加限加$玩印面n洲匆s性腺发生、分化及发育的周年变化相卵母细胞为主，细胞质中的卵黄核己消失，平均成熟系数为3.35%。11月性腺处于IV期，此期精巢内精细胞正处于不同的形成过程中，平均成熟系数为0.93%；卵巢中以4时相卵母细胞为主，胞质中充满染成桔红色的卵黄颗粒。

Inthe whole process, the oocytes, nurse cell and follicle cell morphology change. Inoocyte yolk formation and growth, the number of its nuclear trophoblast cell nucleoli,lamphrush chromosome with a strong synthetic material; oocytes also some syntheticmaterial; follicle cells in the yolk protein synthesis, provide access to exogenous yolkprotein.

在卵子发生的整个过程中，卵母细胞、滋养细胞及滤泡细胞形态均有明显变化；在卵母细胞生长及卵黄形成期，滋养细胞核内的多核仁现象、灯刷染色体与旺盛的物质合成有关；卵母细胞本身也合成一些物质；滤泡细胞参与卵黄蛋白的合成，并为外源性卵黄蛋白提供通道。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
