水杨酸钠

The charomatographic conditions of separation and direct dermination of benzophenone-4(MS40), salizyle acid sodium, salol, benzophenone-3(M40), octyl dimethyl PABA(6007), butyl methoxy dibenzoyl methane(1789), octyl methoxyl cinnamate and octyl salicylate(587) from u-Bondapak C18 Column were studied with methanol-water-THF as elution. A HPLC method for these compounds was founded.

Objective: To determine the effects of sodium salicylate on cochlear blood flow and explore the mechanism of salicylate ototoxicity.

提要 目的：检测水杨酸钠对耳蜗血流量(Cochlear blood flow，CoBF)的影响，探讨水杨酸盐耳毒性发生的机制。

In Dex-pretreated group, no changes in CoBF was found after the administration of salicylate sodium.

水杨酸钠可减少耳蜗血流量，地塞米松可减轻水杨酸盐对耳蜗血流量的影响，内耳花生四烯酸代谢异常可能介导了水杨酸盐耳毒性的发生。

Objective To investigate the expression of HSP27 in cochlea of rat induced by sodium Salicylate injection and determine its effect and significance in sodium salicylate ototoxity.

目的 研究水杨酸钠作用后大鼠耳蜗热休克蛋白27(heat shock Protein27，HSP27)的表达特点，探讨HSP27在水杨酸钠耳毒性中的作用及意义。

Sodium naphthalene acetate, sodium salicylate and abscisic acid showed strong inhibition and toxicity to water cultured seedlings.

萘乙酸钠、水杨酸钠、脱落酸等对水培幼苗生长表现出强烈的抑制和毒性。

The influence of different nutrient substrates added in the degradation experiments was also studied. It was showed that sodium salicylate, sodium acetate and yeast extract had obvious stimulative effect, but glucose had no obvious effect.

研究了添加不同营养物质对降解性能的影响，水杨酸钠、醋酸钠和酵母膏对混合菌降解芘有明显的促进作用，葡萄糖的作用不明显。

The results suggest that administration of sodium salicylate can decrease the expression of NGB mRNA and protein of spiral ganglion cells in guinea pig and these changes are relative with the dosage of sodium salicylate.

水杨酸钠可显著降低螺旋神经节神经元NGB mRNA和蛋白表达；水杨酸钠对螺旋神经节神经元NGB mRNA和蛋白表达是剂量依赖性的。

Adriamycin , sodium salicylate and acyclovir were used as model drugs to investigate the encapsulation efficiency of alginate-chitosan microcapsules to drugs containing different kinds of charge.

以阿霉素、水杨酸钠与阿昔洛韦为模型药，考察海藻酸钠-壳聚糖微囊对电性不同的药物的包封率。

First take the administration team group first forIM model making by given ranitidine 0.06g and the 5％hyperhaline typical finemixtured powder with the 50ug/ml MNNG, 0.1％ammonia water,2g sodiumsalicylate added into 100ml 30％alcoholic solution for intragastric administration 6weeks and the nomal control group by given the ordinary feeds and commonwater;After 9 weeks administration,the model groups rats was put to death for modelmaking detection.

从实验第一天起正常对照组给予普通饲料和正常饮水；模型组大鼠则食用含0.06雷尼替丁和5％的高盐的标准粉末状混合饲料，给予含有浓度为50μg／ml的甲基硝基亚硝基胍溶液每日自由饮用，MNNG溶液装入涂有黑漆的避光饮水瓶内，每24 h更换1次药液，每周饮5天，周2和周5则给予浓度0.1％的氨水饮用；同时将2g水杨酸钠放入100ml 30％的酒精溶液中，配置成2％的水杨酸钠和30％的酒精的混合溶液，从第4周起每天早上9点灌胃。

Methods: Using the light microscope, scanning and transmission electron microscope,the morphology of the Corti of organ was observated, especially the outer hair cell s in the guinea pig with acute or chronic sodium salicylate/saline injection.

采用单次和长期注射水杨酸钠建模分别在光镜、电镜下观察 1次及多次注射水杨酸钠组和生理盐水对照组豚鼠耳蜗基底膜Corti器，特别是外毛细胞形态的改变。
