To properly explore the photoreceptor for the negative phototropism in rice (Oryza sativa L.) root, lights with different wavelengths were applied to investigate the effect of light quality on phototropic response. The negative phototropic bending could be induced prominently by blue/UV light, while not be induced by red and far-red light.

为了研究水稻根负向光性的光受体，观察了光质对稻根的负向光性效应，用紫外－可见分光光度计测定了水稻根冠浸提液的吸收光谱，并对根冠中的蛋白质进行了SDS-PAGE电泳分析。

Antagonists of GABAA receptor/Cl一channel, picrotoxin and bicuculline,have no effect on the progesterone-induced AR,but they can significantly inhibit the GABA-induced AR in Cl--containing medium.

在含CI一培养液中，GABA*受体拮抗剂picrotoxin和bicuculline不抑制孕酮诱发的顶体反应，而抑制GABA诱发的顶体反应。

CGP35348 can completely stop the change of free-calcium concentration induced by GABA, while Picrotoxin didnt affect this effect induced by GABA.

由GABA引起的效应可以被CGP35348完全阻断，而Picrotoxin对此效应没有影响。

While in Cl--deficient medium,picrotoxin has significant inhibitory effect on both progesterone- and GABA-induced AR,both progesterone- and GABA-induced AR are inhibited by the Call channel blocker,nifedipine.

相反在缺CI一培养液中，picrotoxin则可明显地抑制孕酮和GABA诱发的顶体反应。孕酮和GABA诱发的顶体反应均可被Cal+通道抑制剂nifedipine阻断。

Propofol induced Cl- currents at concentrations of 10-5 and10-4 M, which were sensitive to picrotoxin and, to a lesserextent, to strychnine. Propofol (10-6 M) enhanced -aminobutyricacidA (GABAA; 10-6 M)-induced current synergistically. Moreover,propofol (10-5 and 10-4 M) significantly increased the decaytime of evoked-inhibitory postsynaptic currents, which suggestsa postsynaptic modulation of GABAA receptors.

异丙酚在浓度10-5~10-4M 时，産生 Cl-电流，对印防己毒素敏感，在更小浓度范围内，对番木鼈碱敏感。10-6M 的异丙酚加强 GABAA 産生的电流，另外，异丙酚（10-5、10-4M ）显著地增加了突触后诱发-抑制电流的衰退时间，提示了 GABAA 受体的突触后调节作用。

Neuronal death in hippocampus in epileptic rats induced by pilocarpin includes necrosis and apopto is. Oxidative stress is involved in hippocampal neuronal damage in epileptic rats induced by pilocarpine.

PILO诱导的海马神经元死亡包括坏死和凋亡两种形式，氧化应激机制参与了PILO诱导的海马神经元损伤。

On the other hand the proliferation activity of ConA-induced splenocytes was enhanced by polysaccharide fraction of Hoshouwu. In mucosal immunity, although polysaccharide fraction of Hoshouwu might not be an effective adjuvant, it enhanced IgM antibody production induced by Pneumococcus vaccine.

何首乌甲醇粗萃物促进自然杀手细胞活性和增强骨髓系造血反应，而何首乌高分子提升全身免疫作用的 T 细胞活性；肠道黏膜系统免疫反应方面，虽然何首乌高分子无法作为有效的佐剂，但可加强肠道病菌感染时的 IgM 抗体反应。

The black sesame is rich in biotin, it has the best effect of hair lost which be caused physical weakness and progeria so as to the drug-induced hair lost and certain diseases-induced hair lost.

黑芝麻富含生物素，对身体虚弱、早衰而导致的脱发效果最好，对药物性脱发、某些疾病引起的脱发也会有一定疗效。

To investigate the effect of p38MAPK signal conducting pathway on livercancinoma cell's malignant phenotype induced by VEGF,we take theexperiment with cell growth test,scanning microscope and laser scanningconfocal microscope so that observe effect of p38MAPK signal conductingpathway on liver cancinoma cell growth,pseudopodium formation andframework of cytoskeleton induced by VEGF.results indicate that the cellbecame ellipse and there were more and thick pseudopodium in the cell'ssurface after being treated by VEGF,and destroyed framework ofcytoskeleton,which can be blocked by pretreated with a special inhibitor ofp38MAPK SB203580 so that VEGF promote metastasis by enhancing livercell migration and movement via p38MAPK signal conducting pathway,butVEGF promote cell growth without p38MAPK signal conducting pathway.

为进一步探讨VEGF通过p38信号传导通路诱导肝癌细胞转移时，对肝癌细胞恶性表型的影响，采用细胞增殖实验、扫描电子显微镜、激光扫描共聚焦显微镜观察VEGF对肝癌细胞增殖作用、细胞伪足形成、细胞骨架微丝结构的影响以及p38MAPK信号通路调控作用。结果显示，VEGF能够不通过p38信号通路促进肝癌细胞增殖；VEGF诱导肝癌细胞丝状伪足增多、增长，使细胞骨架微丝结构破坏、甚至消失。阻断p38MAPK信号通路，可以抑制VEGF诱导的肝癌细胞伪足形成，细胞骨架丝状结构呈束状，排列较规整。上述结果表明，VEGF可以通过p38信号传导通路诱导肝癌细胞伪足增多、增长，促使细胞骨架微丝结构破坏，使肝癌细胞迁移、运动能力增加，促进肿瘤转移。VEGF并不通过p38信号通路诱导肝癌细胞增殖作用。

The pyrexia may have negative influence on prognosis for patients with acute brain stroke. The treatment for infection and danger factors of infection is important for patients with acute brain stroke. The early identification for infection-induced pyrexia and uninfection-induced pyrexia is of great clinical significance.

急性脑卒中后发热影响患者的预后，感染与易感因素防治是急性脑卒中综合治疗的重点，感染性发热与非感染性发热的鉴别和深入研究具有重要临床意义。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
