The former, intracranially complements patients some factors, most frequently with TH gene to compensate scanty of intrastriatal DA and improve the symptoms of the patients, while have little resistance to the progressive degeneration of dopaminergic neurons; The latter provide variety of neurotrophic factors, most specific being the glial cell-line derived neurotrophic factor , to protect the residual DA neurons in the nigrostriatal system from further pathogenic injuries, while have little benefit to those DA neurons with irreversible damage, and them cannot offset the already-existing symptoms.

前者是给宿主脑内补充某些因子，主要是DA合成过程中的限速酶TH基因，以补充纹状体内DA含量的不足，减轻患者的症状，但对DA能神经元的进行性退变没有治疗效果；后者则是提供各种神经营养因子其中最具特异性的为GDNF，以保护黑质一纹状体系统内剩余的DA能经元免受病因的继续损害但对已发生不可逆性损害的DA能神经元并无拯救作用，无法消除已出现的症状。

Phosphatases all took part in transporting degraded product of nucellus, transporting reverse material from apoplast to endosperm cell, degeneration of starchy endosperm nucleus.

磷酸水解酶共同参与了珠心降解产物向胚囊中的运输、营养物质从质外体向胚乳细胞中的运输、细胞核的解体。

And the biological characteristics of the seven strains were reported in this paper, which include nutrition materials, cultural conditions, growth graph, cultural characters of mycelium, sclerotium and colony, mycelial differentiation, sclerotial differentiation and development.

将这7个菌株作为供试菌株，进行了一系列的生物学特性研究，包括营养基质、培养条件、生长曲线、茵丝体培养特征、菌核培养特征、菌落特征、菌丝分化以及菌核分化发育等。

Placenta as a key temporary organ for maintaining oxygen and nutritive substance exchange in universe and foetus contained immature embryon and adult stem cells that trended to maturity no matter from anatomic structure or growth, besides, placenta could not be related to ethics.

胎盘作为胚胎发育中维系母体和胎儿氧气及营养物质交换的重要暂时性器官，无论从解剖结构还是在发育行为上，都包含了较为幼稚的胚胎及趋于成熟的成体干细胞成分，而且胎盘不会涉及伦理道德问题，目前已成为寻找人类间充质干细胞新来源及提高临床应用效果的研究热点。

Co-transformation of plasmid pGg-gfp and plasmid pCc1001 which harbors the complementary gene trp1 was conducted by the PEG-mediated protoplast transformation of the oidia of LT2, a tryptophan auxotrophic strain of Coprinus cinereus.

采用PEG介导法把表达质粒pGg-gfp与辅助质粒pCc1001（含有trp1基因）共转化进色氨酸营养缺陷型的灰盖鬼伞粉孢子的原生质体中。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
