Being as a NO donator,L-Arg siguitlcanfly enhanced the ability of TNF-α which increasing permeability of strial capillary cndothelial cells;permeation rate to Evans blue beightened significantly(P＜0.01),which obviously rose up when the concentration of Evans blue added.L-NMMA,NO inhibitor,was able to weaken the ability of TNF-α which increasing permeability of strial capillary endothelial cells:permeation rate to Evans blue decreased siguificantly (P＜0.01),which obviously fell down when the concentration of L-NMMA added.

一氧化氮(nitric oxide，NO)供体L-Arg能增加TNF-α作用下耳蜗血管纹微血管内皮细胞的通透性，使伊文思蓝的通透率升高，差异具有统计学意义(P值均＜0.01)，且随着L-Arg浓度的增加内皮细胞对伊文思蓝的通透率也明显增加。

It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.

研究结果表明，在铝(30 μmol/L)胁迫条件下柱花草根伸长受阻、根尖丙二醛含量和抗氧化酶活性显著增加，而硅(1.4 mmol/L)处理增加根中硅的含量而降低了铝对根伸长、MDA含量和抗氧化酶活性的影响，且铝处理前12h供给的硅和前处理溶液及铝溶液中均加硅处理的影响均显著；在不加硅条件下西卡品种的耐铝性显著低于其它品种，而经硅预处理的植株和在预处理及铝处理期间均供应硅的植株的耐铝性不同品种间的差异不显著。

METHODS: Rat mesenchymal stem cells at passage 3 were obtained under sterile condition, and divided into groups A-F. In group A, iodine ion was not added. In groups B-F, iodine ion at mass concentrations of 2, 55, 90, 125 and 2 500 mg/L was added respectively.

The supernatant was removed. The wells were divided into five groups with 12 wells in each group. The control group was added with 1 g/L dimethyl sulphoxide and 3.3 mmol/L or 16.7 mmol/L glucose, 1 mL per well. The four experimental groups were added with 1 mL 0.2 μmol/L, 1 μmol/L, 5 μmol/L, or 10 μmol/L clozapine apart from the above DMSO and glucose.
