可以抑制的

METHODS: The maximum number of platelet binding sites and their affinity for [3H]-rauwolscine, a selectie alpha 2-AR antagonist, were measured in unmedicated and medicated major depressed patients and in normal olunteers.

背景：曾认为抑郁症可以伴随中枢α2肾上腺素受体密度的降低，继发突触前儿茶酚胺神经元负性反馈的损害，导致刺激后去甲肾上腺素输出和释放去抑制功能的减弱。

Objective To explore the expression of Fas ligand in urogenital malignant cell lines and renal cell carcinoma.

Fas系统（包括Fas分子和FasL及其信号传导分子）在恶性疾病中的生物学作用还没有完全了解，但它在凋亡中的作用表明了它可以做为肿瘤生长的抑制因子。

Objective:To study the changes of excitatory and inhibitory amino acid content in hippocampus of pentetrazole-induced epileptic rats treated with volatile oil of Valeriana officinalis L,and explore the possible antiepiletic mechanism.

谷氨酸是中枢神经系统主要的兴奋性氨基酸之一，可以导致神经细胞兴奋性增加和细胞损害，在癫痫的发病机制中有着重要作用，γ-氨基丁酸则是主要的抑制性神经递质。

Further studies are underway to investigate the exact intracellular mechanisms underlying the effects of the two substances. In Chapter 4, we observed the effects of metabolites of mangrove fungus Xylaria sp. from the South China Sea Coast, Xyloketal A～D, on the activity of acetylcholinesterase in vitro, and the present data indicated that AChE activity was remarkably inhibited by Xyloketal A～D in a dose-dependent manner.

另一方面，在论文第3章离体豚鼠回肠收缩实验中，发现323-A和323-B可剂量依赖性地抑制组胺、乙酰胆碱以及氯化钾所引起的GPI收缩，pD2'依次为5.13、4.97、5.36和5.51、5.56、5.62，并且，通过机制分析发现，323-A和323-B可以显著降低在外界无钙离子存在时由细胞内钙储库释放钙所产生的收缩反应，而对由细胞外钙离子内流所引起的收缩无明显影响。

The initiative and passive methods to decrease the vibration have been studied. The results of decreasing of vibration with the installing of hydraulic liners between the chocks and stand have been researched using the simulation software. The hydraulic liners can decrease or eliminate the vibration effectively.

研究了轧机垂直系统主动减振和被动减振的措施和策略，并运用仿真分析手段，研究了轴承座与机架间采用液压衬板的减振效果，发现采用液压衬板可以很好地抑制轧机垂直系统自激振动的发生。

TNF-α can increase the expression of MMP-2 and MMP-9 and this increase can be counteracted by IFN-γ.

TNF-α对MMP-2和MMP-9的活性有增强效应，但IFN-γ的抑制MMP-2和MMP-9作用可以抵消TNF-α的增强效应。

The latency of the waves of SEP or MEP is extracted. But it still is the best in all. The control group is the worst of all. The wave can be found again after the spinal cords are hemisectcd in control group. 5.. Seen from the immunohistochemistry of NF, Schwann cells can promote neural dendrite outgrowth toward the area of hemisected spinal cord.

神经纤维的兔疫组化染色脊髓半切损伤后，经NF的免疫组织化学技术染色显示：移植雪旺细胞可以促进神经纤维向脊髓损伤区域生长，抗体封闭 LI后神经纤维的生长受到抑制，再生神经纤维数相对减少，这从免疫组织化学方面说明口对神经再生具有影响。

The σ and Laves phases were suppressed, and the microstructural stability increased with decreasing Cr and Si contents.

铬和硅含量的降低，可以延缓或抑制σ相和Laves相的形成，增加合金的组织稳定性。

The counter attack tactics of fencing is one of ripostes to control combatants offensive action and it s important method to gain points directly of many duellists .

击剑的反攻战术属于一种积极防御方法，可以有效地抑制对手的进攻，是诸多重剑运动员直接得分的重要手段。

The results show that the fuzzy PI controller and the control strategy suppress the vehicle oversteering or understeering by the effective control of the brake force and the vehicle control stability is improved significantly.

结果表明：所设计的模糊PI控制器及控制策略可以通过制动力控制有效地抑制汽车的过多转向或不足转向趋势，提高汽车的操纵稳定性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
