The luminosity of the most of extraglactic H2O megamaser sources is between tens and hundreds L ⊙, but one of the extragalactic H2O megamaser source TXFS 2226-184 is 6100 L ⊙. It belongs to the class of radio galaxy and is not general. It is mainly caused by its wide spectral profile.

多数河外H2O超脉泽源的光度在几十至几百个 L ⊙之内，但TXFS2226－184源的河外H2O超脉泽源的光度达6100 L ⊙，它属于射电星系类型，是主要由于其谱线轮廓较宽所造成的一种例外情况。

In fundic strips, ghrelin and GHRP-6 could decrease the on-response induced relaxation and increase off-response induced contraction of the muscle, with the effect of Ghrelin obviously stronger than that of GHRP-6.L-NNA could increase the effects of Ghrelin and GHRP-6-induced muscle contraction, and L-AA could decrease their effects.

在胃底部，Ghrelin和GHRP-6可使开电刺激诱导的平滑肌舒张活动减弱，断电刺激诱导的肌条收缩活动增强，且Ghrelin作用明显强于GHRP-6.L-NNA可显著增强Ghrelin和GHRP-6的促平滑肌收缩效应，但L-AA可显著减弱该作用。

Methods The inhibitory effects of Taurine (50 mmol��L-1) on glycolaldehyde (0.1 mmol��L-1) induced DNA damage in spleen lymphocytes of mice were studied in vitro using single cell gel electrophoresis,and 2,4-dinitrophenylhydrazine measurement was used to detect quantitatively the effects of Taurine on carbonyl compound contents in a reactive system.

采用单细胞凝胶电泳技术检测牛磺酸（50 mmol·L-1）对乙醇醛（GA， 0.1 mmol·L-1）所致小鼠脾淋巴细胞DNA损伤的抑制作用，并用2，4-二硝基苯肼法定量检测牛磺酸对反应体系中乙醇醛含量的影响，同时设乙醇醛阳性对照组和PBS阴性对照组。

Results After 50 mmol��L-1 Taurine was added to the spleen lymphocyte suspension containing 0.1 mmol��L-1 glycolaldehyde, the cellular DNA damage rates were markedly decreased (P.01) and the migration distances of DNA were significantly reduced (P.01) as compared with positive control group, and Taurine reduced the carbonyl compound contents in a reactive system in a dose-dependent manner.

结果：在0.1 mmol·L-1乙醇醛溶液中加入50 mmol·L-1牛磺酸后，小鼠脾淋巴细胞DNA的损伤率较阳性对照组明显降低（P.01），彗星实验的迁移距离也显著缩短（P.01），牛磺酸呈剂量依赖性明显降低反应体系中乙醇醛的含量。
