免疫抑制的

Methods: Based on the theory of "kidney produces sui", we set up MCAO rat model. Five indexes including Nestin, PSA-NCAM, MAP-2, GAP-43 and SYN38 were measured in situ hybridization and immunohistochemical methods to evaluate the effects of Fujian Tablet on the proliferation, migration, differentiation of neural stem cells, axonal growth and synapse formation. Other two indexes including trk-B, NOGO-A were used to assess the effects on the neurotropic factor and inhibitory factor.

以&肾生髓&的理论为依据，以MCAO大鼠为实验对象，利用原位杂交技术和免疫组织化学方法，分别以nestin、PSA-NCAM、MAP-2、GAP-43、突触素p38为指标，观察复健片对神经干细胞增殖、迁移、分化、轴突生长、突触形成的影响；分别以trk-B、NOGO-A为指标，观察复健片对神经生长营养因子、抑制因子的影响。

To investigate the bioactivity of Nocardia rubra Cell, the mice were used to assay the toxicity, the effects on immune organs, phagocytes of peritoneal macrophage and the antitumor activity by perfusion of NC to the stomach of mice.

摘 要：为了考察红色诺卡氏菌菌体的生物活性，通过一定浓度的NC对小鼠灌胃给药，检测其毒性及对免疫器官、巨噬细胞吞噬功能的影响和对肉瘤S180抑制作用。

It has been reported that sulfation of polysaccharides affect strongly on their immunocyte activity and anti-tumour bioactivities, but the sulfatation of polyporus umbellatus polysaccharides has not been reported.The thesis synthesize the sulfate polyporus umbellatus polysaccharides for the first time.

据报道，多糖的硫酸酯化对多糖的免疫细胞活性、抑制肿瘤等生物活性等有很大影响，但是国内外未见猪苓多糖硫酸酯化的相关研究与报道，本实验首次制备得到猪苓多糖硫酸酯，具有创新性。

Methods : MTr assay was used to examine the effect of Sorbaria sorbifolia on the proliferation of HepG-2 cell and flow cytometry was used for the cell cycle distribution.

采用MTT比色法观察珍珠梅提取物抑制肝癌HepG-2细胞增殖；采用流式细胞仪检测其对HepG-2细胞周期分布的影响，同时结合倒置显微镜、HE染色、透射电镜及免疫细胞化学方法检测凋亡相关基因bcl-2、p53的蛋白表达，观察其诱导肝癌HepG-2细胞凋亡的作用。

Excessive sun exposure can suppress your skin's immune system, making you more susceptible to infection.

过度暴露於太阳的能抑制你的皮肤的免疫系统，使您更容易受到感染。

Excessive sun exposure can suppress your skin's immune system, making you more susceptible to infection.

过度暴露于太阳的能抑制你的皮肤的免疫系统，使您更容易受到感染。

All above results clearly indicate that Maitake D-fraction substantially potentiates the activity of cellular immunity, and that it i inhibits tumor growth, ii prevents tumor metastasis, iii prevents normal cells from carcinogenesis and iv works together with chemotherapy and/or radiation.

以上结果清楚的显示灰树花D-组分可以显著的增强细胞免疫活性。并且它能够：第一抑制肿瘤生长；第二阻止肿瘤转移；第三阻止正常细胞的癌变和；第四辅助放化疗。

Results:It is suggested that the drug significantly protectes liver from CCl4,thioacetamide and galactosamine in mice and rats,lowers the activity of enzyme ALT in serum,shorten the sleep duration of CCl4-damaged mice induced by embuter,inhibites HBsAg in vitro,and potentiates non-specific immunity in mice and rats.

结果：研究表明，该药对四氯化碳、硫代乙酰胺和氨基半乳糖引起小鼠及大鼠的急性肝损伤有明显的保护作用，能降低谷丙转氨酶；缩短CCl4肝损伤小鼠戊巴比妥钠的睡眠时间；抑制体外乙肝病毒表面抗原；对非特异性免疫有一定增强作用。

Severe deficiency of the vitamin may impair cell-mediated-immunity and stimulate tumor growth by activating gene transcription, while megadose of B6 could improve the celluar-imunity against development of neoplasms.

近年来人们发现B_6除具有上述作用外，尚具有抑制肿瘤生长的作用，机体如果缺乏B_6除可造成细胞免疫力下降外，还能通过激活转录作用促进肿瘤增殖；故当补充B_6时则可改善机体的细胞免疫功能，对抗肿瘤的发生和发展。

Second, because the thoracic duct drainage can be particularly lymphocytes from the large number of T cells in vitro, to reduce its dermal layer deposition, as well as the release of lymphokines, resulting in T-cell subsets change, helper T cells and the inhibition of T-cells ratio decreased the humoral immune function, B cells to produce specific antibodies decreased.

二是因为胸导管引流术可以把淋巴细胞尤其是T细胞大量排出体外，减少其在真皮层内的沉积，以及淋巴因子的释放，从而导致T细胞亚群的改变，辅助性T细胞与抑制性T细胞比值下降，体液免疫功能改变，B细胞产生特异性抗体能力下降。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
