Results: Small round or linear haemorrhagic erosions were induced in the oxyntic glandular area after rats exposed to WRS. Meanwhile, GMBF decreased and NO contents in plasma and gastric mucosa increased significangly compared with those without WRS. L-NAME not only further decreased GMBF and inhibited the increases of NO contents but also aggravated the extent of gastric mucosal lesions. In contrast, L-Arg increased both GMBF and NO contents resulting in the lessening of mucosal injuries. All these changes were significant compared with control group.

结果：浸水束缚应激4 h可致严重的胃粘膜损伤，同时粘膜血流量明显下降，血浆及粘膜NO含量明显升高，与正常对照组相比差异非常显著（P＜0.01）；L-NAME明显加重粘膜损伤，并阻抑了应激所致的血浆及粘膜内NO含量的升高，使粘膜血流量更趋下降，与实验对照组相比差异显著（P＜0.05）；L-Arg可明显升高粘膜血流量及血浆、粘膜内NO含量，明显减轻粘膜损伤程度，与实验对照组相比差异非常显著（P＜0.01）。

The effect was attenuated by preadministration of L-arg.

提示L-arg：NO通路参与睡-醒周期节律的调节。

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。

L-Arg therapy in rever sing acute hypoxia is better than Dex therapy.

L-Arg较地塞米松能改善急性缺氧的病理生理反应。

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。

L－Arg－NO pathway may tonically inhibit blood pressure,which may be mediated through r-aminobutyric acidreceptor.

结论PAG内L－Arg－NO通路对动物血压有紧张性抑制作用，可能是通过GABA受体介导。

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.

久效磷在淹水土壤中降解为甲醇可抽提态和不可抽提态残留物，对甲醇可抽提态残留物经TLC和红外光谱分析表明，其降解物为磷酸三酯、N-去甲基久效磷、O，O-二甲基乙烯基磷酸酯，0-去甲基久效磷，以及O，C-去甲基久效磷，但主要为磷酸三酯，其含量由母液中的5％增加到28—83％，这种降解过程，在未灭菌土壤中比在灭菌土壤中快。
