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。

The seedlings of Fagopyrum tataricum were treated with 0.1 mmol/L, 0.3 mmol/L and 1.0 mmol/L of glyphosate, respectively. The result showed that the flavonoids metabolism in F. tataricum seedling was inhibited obviously.

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。

The standard curves for glyoxal and glyoxalic acid both had good linear relations in the ranges of 2~20 mg/L and 10~100 mg/L, respectively.

乙二醛质量浓度在2～20 mg/L范围内，乙二醛二腙的峰面积与乙二醛的质量浓度之间呈良好的线性关系；乙醛酸质量浓度在10～100 mg/L范围内，乙醛酸腙的峰面积与乙醛酸的质量浓度之间呈良好的线性关系。

Don.methodswith the stem of sterile seedling and fresh plants as exophyte, ms as a basic medium, 6-ba and naa hormone were adopted as the experimental variables.resultsms +1.0 mg / l 6-ba +1.0 mg / l naa induced the best effect of callus; higher concentrations of 6-ba with high concentrations of naa made callus densification and higher rate.conclusion different plant hormones and their different concentration ratios have different effects on the callus of halenia elliptica d.

方法以椭圆叶花锚种子培养的无菌苗的茎和新鲜植株的茎段为外殖体，ms为基本培养基，分别以6-ba和naa两种植物激素为变量进行实验研究。结果ms培养基+1.0 mg/l 6-ba+1.0 mg/l naa对诱导椭圆叶花锚愈伤组织的形成效果最佳；高浓度的6-ba配合较高浓度的naa诱导的愈伤组织致密，出愈率高。
