Japonicus and analyzed the role of animal process of oocyte during ovulation and oocyte maturation. What's more, we studied the role of microtubules and microtubule organizing center upon GV migration. The oocyte of A. japonicus connects to the follicle via animal pole process.

The expression level of metabolitic enzyme (CYP1A1, CYP1B1) and its correlation with cell differentiation /apoptosis were studied as well. The influence of resveratrol in cell cycle was determined with FCM. Results 1 Resveratrol not only suppresses the growth of medulloblastoma cells in a dose and time related fashion but also induces cell differentiation and apoptosis. Resveratrol promotes differention of UW228-1,-2 cells to forward glia, UW228-3 and Med-3 cells to neuron. A treatment of resveratrol in the concentration of 100μM for 48hrs comit most of cells die of apoptosis. 2 Among the four cell lines Fas and Caspase-3 were constantly expessed, whereas FasL was absent irrespective to the drug treatment. 3 ICC, RT-PCR, Western-blot hybridization and EROD enzymatic activity assay demonstrated that expression of CYP1A1 is different after treatment with resveratrol in four cell lines, up-regulated in three UW228 cell lines in a dose dependent manner but down-regulated in Med-3 cells. Suppressive effect of resveratrol on CYP1B1 expression is the same among four medulloblatoma cell lines. 4 Cell cycle distribution of UW228-3 was greatly changed after treatment.

结果：1、白藜芦醇以时间和剂量依赖性方式抑制髓母细胞瘤细胞生长，同时促进细胞的分化和凋亡：白藜芦醇促使UW228-1、-2靶细胞向神经胶质细胞方向成熟分化，UW228-3、Med-3细胞向神经元细胞方向成熟分化，以100μM作用48小时效果显著；2、四个细胞系均有Fas和Caspase-3表达，但无Fas-L基因表达和蛋白活性产生，因此难以形成Fas相关性死亡通路；3、白藜芦醇处理前后CYP1A1基因的表达在各细胞系略有不同：UW228-1，-2，-3三个细胞系白藜芦醇以剂量相关性方式上调CYP1A1的表达，而Med-3细胞系，白藜芦醇却抑制CYP1A1的表达；四个细胞系在白藜芦醇处理后CYP1B1的表达均受到抑制；4、UW228-3细胞系经白藜芦醇作用后细胞周期有较大改变，表现在G0/G1期在整个细胞周期中所占的比例增加，而其它时期则相应减少。

用10％的蜂蜜和清水分别饲喂两组成虫(简称"蜜组"和"水组")，以研究成虫期的营养对Vg发生和卵巢发育的影响，结果显示，成虫期营养对于Vg的启动合成并不起关键的决定性作用，两组成虫均可以在羽化的48小时检测到Vg，且水组中的血淋巴水平并不低于蜜组对照，但绝大多数水组个体的卵巢发育停留在卵黄沉积的某一时期，此时在血淋巴中也检测不到，只有约20％的饲水个体卵巢可以发育成熟，出少量卵；用高剂量的ZR515于羽化当日点滴处理饲水个体，可以使所有接受处理的饲水个体的卵巢发育成熟，但是产卵〓依旧低于对照组的，不能恢复正常；这说明成虫期营养对卵巢中全体卵母细胞的成熟是必需的，其作用的产生是通过内分泌系统途径实现的。

DCs acquired by our reformed methods express both CD83 and CD 14 molecules highly, and have a higher density than other domestic reports. The higher TNF in DCs culture medium of HC patient suggests DCs in patient still have antigen presenting ability and by optimization the culture medium would improve its presenting ability and have a potential value in design and application individual vaccine. Although antigens pulsed DCs have a decrescent antigen presenting ability but BCG HSP70 could induce its mature and improve its presenting ability. Suggests BCG HSP70 would be a useful mature inducer. Lymphocytes primed by DCs based HC vaccine have the specific cytotoxicity against HCC lines. The CTL after freezing and anabiotic could prophylaxis and therapy HC xenograft on nude mouse. The results also suggests that CD4〓 lymphocytes play a important role in HC with a good differentiation and would be useful in treatment this kind of HC. After being activated by Peptide LLNQHACAV of hAFP and apoptotic HCCs pulsed DCs respectively, the culture medium of activated lymphocytes both contains a high level Th1 cytokines IL-12 and TNF. Primed lymphocytes appeared a characteristic of NK cells. DCs not only inhibited the growth of human HCC and other cancer cells in vitro but also prevented the growth of HC xenograft on nude mouse in vivo. There are at least three kinds of mechanism playing important role in DC based vaccine ,there are inhibition of DCs, HC specific CTL and cytokines pathway.

These results suggest that in the central nervous system of small mammals, AP waveforms mature rapidly in many types of neurons, thus, coordinated activities in neuronal circuits may occur. In early postnatal development, GABA receptor mainly mediates an excitation effect, depolarizes P6 MGBv neurons and dramatically increases the frequency of AP firing. Inhibition of GABA receptor matures slowly along with increment of postnatal days.

The meiosis of oocytes differ from mitoses of general cells. Especially in most mammalian species, oocytes are formed during fetal life, but they are arrested at the prophase stage of the first meiotic division until around the time of ovulation.

卵母细胞的成熟分裂有别于一般细胞的有丝分裂，尤其是哺乳动物，在胎儿期或出生后不久，初级卵母细胞就陆续进入第一次成熟分裂前期阶段，但长时间的&休止&于此期，直到性成熟时在促性腺激素等因素的作用下，第一次成熟分裂才重新启动。

Japonicus.Nerve extraction substance of sea star and dithiothreitol has been reported to be effectively to induce oocyte maturation in sea cucumbers. In this study we tested their effects on oocyte maturation induction in sea cucumber A. japonicus. The results are as follows, oocyte of A. japonicus does not get mature spontaneously. Neither NES alone nor NES with follicle suspension can induce oocyte maturation. While DTT can prominently increase the percentages of germinal vesicle break down. When the concentration of DTT is between10-1 mol/L and 10-3 mol/L, the effect of maturation induction is more sufficient. When the concentration is about 10-2 mol/L, the percentage of GVBD can reach up to more than 90%.
