The yolk proteins were collected through the anatomization of the maiden eggs and the eggs in different embryo development stages. The yolk proteins were separated by two-dimensional electrophoresis and followed the image analysis. Over 203 protein spots were found to exist in the yolk protein of silkworm eggs. Some different patterns of yolk protein spots were found in silkworm of various varieties. While, little variation of yolk proteins was detected during different development stages of any silkworm variety.

In ovary, PNA receptors appeared in the oocyte cytoplasm of second phases of oogenesis; the positive granules gradually increased from third to forth phases, and they exhibit a maximum expression before vitellogennic stage in cytoplasm of oocyte; from vitellogennic stage to chorionation stage, the positive granules gradually reduced. Binding sites on follicle cells were changed with their morphological variation in every stage of oogenesis.The staged and specific expression of oncogene c-kit, the tyrosine-kinase receptor, is closely related with gametogenesis.
2在中华蚱蜢卵子发生的早期，PNA受体是由卵母细胞自身合成；在卵黄发生前的准备时期，卵母细胞质中的PNA受体一部分来源于自身合成，另一部分则来源于滤泡细胞，而糖复合物的大量出现可能直接与卵黄发生有关；卵黄发生期PNA受体的减少可能是在卵黄物质形成中部分发生了修饰；卵黄和卵壳的相继形成过程中，阳性反应的出现说明PNA受体参与了卵黄膜及卵壳的形成，而这些受体物质是由滤泡细胞分泌的。

This was the reason of no mature ovum in worker. But worker has a potential ability to turn into reproductives because of its complete differentiation stage and the growth stage in oogenesis.
由于具有完整的卵母细胞分化期和生长期，在巢群需要的情况下受调节可以进一步发育完成卵黄的形成，因此工蚁具有向繁殖蚁转化的能力。

The main conclusions are as follows:The vitellin of Chrysopa septempunctata was extracted with 0.4mol/L NaCl and then precipitated in cold distilled water. Ion exchange chromatography and proteic gel recovery were used to purify it further. SDS-PAGE analysis shows that the vitellin is composed of two subunits, the large one 165kDa and the small one 46kDa.Then automatic amino acid analyzer was used to analyse amino acid composition of vitellin.
主要结论如下：用蒸馏水沉淀法对大草蛉的卵黄蛋白进行了初步纯化，而后又采用离子交换层析和蛋白胶回收的方法对卵黄蛋白进行了进一步的纯化；通过SDS-PAGE分析表明，大草蛉的卵黄蛋白由大165kDa和小46kDa两个亚基组成；用氨基酸自动分析仪对纯化后的卵黄蛋白进行了氨基酸组分分析。

在小鱼开始能自由游动后的三周里，他们靠吸收亲鱼背鳍上的分泌物&七彩奶&过活。至少，在吃完剩卵黄的一周内，他们没有&七彩奶&也不能存活。

At present, the research mainly concentrates on vitellin purification and characterization, vitellogenin synthesis and hormonal regulation, vitellogenin absorption and processing.
目前，对蜱类卵黄发生的研究主要包括卵黄蛋白的纯化与鉴定，卵黄原蛋白的合成与调控，卵母细胞对卵黄原蛋白的摄取以及转变为卵黄蛋白的分子过程。

The results of the determinating the activity of the CA in vitro showed that the CA of the water—fed individuals were in activing statics after eclosion. Because of the apperence of the Vg in haemolymph and the deposition of the vitellin in oocytes in the unfed females, it was shown that the CA in such individuals were in activiting statics, too. Again because in the water—fed females which did not lack the feeding action the activity of the CA showed dropping tendency gradually still, it could be said that the activiting of the CA was possibly effected by the nutrition but it was never related to the adult feeding action. In another respect, the brain of the female adult had not significant effect on the activiting CA. The oocytes could depositing vitellin in individuals removed brain tissue on the day of eclosion, which showed that the activting of CA was not concerned with brain.
CA活性的体外测定说明饲水个体的CA同样具有活性，不取食个体血淋巴中Vg的存在以及卵母细胞中卵黄的沉积表明，在不取食的个体中CA同样具有活性，所以CA的活化与成虫期的取食动作无关，与成虫是否取食花蜜也无太多的联系，但是CA活性的维持可能受成虫期营养的影响，如果以卵母细胞发育和CA体积大小作为CA活性的指标，则饲水个体CA的活性在后期受到了影响，说明饲水不能替代取食蜂蜜来维持成虫期CA的活性；成虫期脑对CA的活化无明显作用，羽化当日摘除脑的个体，其卵母细胞仍然可以沉积卵黄，说明CA的活化与脑无关，而是受某种不确定的因子的影响；用抗JH物质—早熟素—Ⅱ以10ug／虫的剂量在颈部点滴处理雌虫，对Vg的发生和卵巢的发育具有一定的迟缓作用，其原因有待于进一步的研究。

Dorsalis by salting out, ion exchange chromatography, and gel filtration chromatography. By salting out the egg homogenate, SDS-PAGE analysis revealed that the Vns were mainly precipitated in a 50~70% ammonium sulfate solution. The salted-out proteins were further purified by ion exchange chromatography, and the result showed that Vns were mainly eluted with a 0.3~0.5 M sodium chloride gradient. Finally, the elutes of ion exchange chromatography were refined by running them through gel filtration chromatography to obtain purified Vns. SDS-PAGE separated the 48- and 51-kDa purified Vns, and used them as antigens to raise polyclonal antibodies.
利用硫酸铵盐析法初步分离果实蝇卵中的蛋白质，以SDS-PAGE蛋白质电泳分析得知，卵黄蛋白主要在硫酸铵溶液浓度为50~70%时被沉淀出；盐析沉淀所得之卵黄蛋白，再以离子交换层析法进一步纯化显示，卵黄蛋白主要会在0.3~0.5 M氯化钠的浓度范围间被析出来；再将析出液浓缩后，经凝胶过滤层析法做最后的纯化，即获得纯化之卵黄蛋白。
