查询词典 extracellular

The results showed that the activities of extracellular pectin methyltrans-eliminase, pectinase, extracellular C1 and proteinase were activated by asarum essential oils; the activities of pectin methylgalactuionase and intracellular C1 were activated at first, then inhibited and activated again; the activities of intracellular pectin methyltrans-eliminase were mostly inhibited; the activities of Cx were entirely inhibited by asarum essential oils, the percentage of inhibition was in proportion to the asarum essential oil concentration.

结果表明：辽细辛精油对胞外PMTE酶、果胶总酶、胞外C1酶和蛋白酶表现为激活作用，对PMG酶和胞内C1酶则表现为先激活后抑制再激活作用，对胞内PMTE酶主要表现为抑制作用；对Cx酶表现为完全的抑制作用，且酶活抑制率与精油浓度成正比。

The extracellular amino acid neurotransmission levels in hippocampus of free-moving rats were detected by microdialysis with HPLC.3. Results:(1) The extracellular GAB A concentration in the CA1 area decreased immediately after the administration of PTZ but increased at about 3d after PTZ injection and lasted about 2 weeks. However, Glu level increased remarkably after the PTZ injection and decreased at 3d until 14d after PTZ injection.

结果： (1)在发作期，细胞外液GABA的浓度为38119.7±912.7nmol／L，较发作前明显下降，在发作后3天升高，发作后14天仍有升高；而Glu的浓度在发作期为4742.0±201.2nmol／L，较发作前升高，在发作后3天下降，瘫痛大鼠海马区细胞外液氨基酸的动态变化和托毗酷对癫痛大鼠辛l〕经元损伤的保护作用中文提要在发作后14天仍低于发作期。

Arterioles and veinlets, mature vessel indexes, mean perfused fraction, extracellular space and extracellular extravascular space were also calculated.

结果HCC微血管的数目、总面积、异型指数均大于成熟血管，而平均面积、直径和血管间距则相反(P＜0.05)。

The result using inhibitors of Ca〓 channels supported above observation. When Ca〓 channels in plasma membrane were blocked by LaCl〓, verapamil or nifedipine, and the Ca〓 channels in endomembranes opened naturally, extracellular CaM couldn't induce 〓 increase. When Ca〓 channels in endomembranes were blocked by ruthenium red and the Ca〓 channels in plasma membrane opened naturally, extracellular CaM induced Ca〓 increase in guard cells, but the extent of Ca〓 increase was lower than that of control.

使用质膜Ca〓通道抑制剂LaCl〓、异博定、尼群地平及细胞内Ca〓通道抑制剂钌红的结果支持这种推测：在质膜Ca〓通道被阻断、细胞内Ca〓通道仍正常开放的情况下，保卫细胞〓不能被CaM诱导增加；细胞内Ca〓通道被抑制、质膜Ca〓通道正常开放的条件下，细胞外CaM诱导保卫细胞内〓升高的幅度不能达到不使用Ca〓通道抑制剂的水平。

Objective:To investigate the role of purinergic P2z receptors in human leukemic lymphocyte apoptosis induced by extracellular adenosine triphosphate.

目的：研究嘌呤能P2z受体在介导慢性淋巴细胞白血病细胞凋亡中的作用。

P2X receptors are membrane ion channels activated by the binding of extracellular adenosine triphosphate.

P2X受体是一些膜上的被细胞外三磷酸腺苷激活的离子通道。

This is the website for the Cell Adhesion and Extracellular Matrix Centre in the University of Manchester.

这是曼彻斯特大学细胞附着和细胞外基质研究中心的网站。

Excessive aggradation of extracellular matrix in the liver is the pathologic characteristic of hepatic fibrosis.The development of liver fibrosis is a dynamical process which is mainly due to the activation of the hepatic stellate cells, including not only excessive synthesis of ECM, but also its deficient degradation.

肝纤维化以细胞外基质在肝脏弥漫性过度沉积为病理特征，其形成主要由于肝星状细胞活化，ECM过度生成，降解相对不足，在肝内大量沉积所致。

These results are very helpful for us to design the agonist and antagonist targeting at the extracellular region.

此研究结果为我们深入研究gp130胞外区的结构和功能以及针对gp130胞外区的小分子激动剂和拮抗剂的研究提供了一些理论依据。
