查询词典 ARG

MATERIALS AND METHODS: Arg to Ser mutation was introduced into the 249 position of the p53 gene by knock-in method. These ES cells with this mutation were selected according to the homologues-recombination with PCR and Southern blot. The positive ES cells without a selection marker were injected into blastocysts recovered from Hprt(superscript -/-) mice, which were derived from Hprt-deficient ES cells. The injected blastocysts then were implanted into pseudopregnant females.

材料与方法：利用基因打靶技术在小鼠胚胎干细胞p53基因249编码子中引入点突变，使编码子249由精氨酸变成丝氨酸，然后将含突变的ES细胞显微注射到Hprt小鼠囊胚中，将注射过的囊胚植入假孕的雌性小鼠子宫，到第14d取小鼠胚胎纤维母细胞，用含HAT的培养液筛选出从ES细胞分化而成的鼠EF细胞，经测序证实细胞含有由249Arg到Ser的突变。

TNF-α can increase permeability of strial capillary endothelial cells of suinca pig cochlea.

TNF-α能使内皮细胞中的F-actin含量明显减少(P＜0.01)，且TNF-α的浓度越高F-acitn的含量降低越明显；L-Arg能进一步降低F-actin的含量(P＜0.05)；而L-NMMA则能抑制这种趋势(P＜0.05)。

Methods Strial capillary endothelial cells in guinea pig cochlea was dissociated and cuhureed to establish a model for its permeability in vitro.,The animals were divided into TNF-α,TNF-α+L-arginine,TNF-α+NG-minomethyl-L-arginine and control groups.

Their half lives were 27.29 and 69.16 days respectively. Monocrotophos degraded into both methanol extractable and unextractable residues in the submerged soil.The analysis of 14C-methanol extractable. residue by TLC and ARG indicated that degraded products of monocrotophos were triether phosphate,;N-de-methyl Azodrin, O, O-dimethyl-vinyl-phosphatc,O-demethyl Azodrin,and O, C-demethyl Azodrin.The principal degraded extratable product of monocrotophos was triether phosphate, which incresed from 5% of the parent solution of monocrotophos to a range of 28-83%, furthermore and its degradation process was much faster in the unterilized soil than in the sterilized soil.
