It was also found that at experimental concentrations there was no regularity for the change of activity of copper salicylate encapsulated in negatively charged liposomes, and copper salicylate encapsulated in liposomes with more negative charges could promote the dismutation of superoxide anion free radicals, however, so could copper salicylate encapsulated in liposomes with fewer negative charges only in lower concentrations.

并发现在实验浓度范围内，负电性脂质体包裹的水杨酸铜，活性变化无规则，且荷负电量多的脂质体包裹的水杨酸铜促进超氧自由基的歧化，而荷负电量少的脂质体仅在低浓度区对超氧的歧化表现为促进作用。

This paper has studied the esterification of isopropanon and salicylic acid in the presence of boronic acid.

When suppurative stopped creators cavity new granulation tissue regeneration, it may choose Iodoform Vaseline (5 : 95), cod liver oil and Vaseline (1 : 1), iodoform Vaseline castor oil (3 : 20 : 10), cod liver oil sulfadiazine salicylic acid (86 : 10 : 4), Zilueshui.

当化脓基本停止创腔内有新生的肉芽组织再生时，可选用碘仿凡士林（5︰95）、鱼肝油凡士林（1︰1）、碘仿凡士林蓖麻油（3︰20︰10）、鱼肝油磺胺嘧啶水杨酸（86︰10︰4）、紫药水、碘仿鱼肝油（1︰9）水杨酸氧化锌软膏（4︰96）等。

In this study, the aged watermelon seeds were selected as material, soaked by different concentrations of salicylic acid, calcium nitrate and gibberellic acid (GA3), to study the effects on germination rate, related physiological and biochemical indexes of aged watermelon seeds. The results show that the activity of aged watermelon seeds was obviously increased after soaking, and the best treatment to promote germination was Ca(NO3)210mmol/L. Besides, conductivity and soluble sugar content of seeds lixivium, and MDA content of seeds were decreased obviously after treated by SA, Ca(NO3)2 and GA3, and SA treatment had the best obvious effects.

本试验以自然老化的西瓜种为试材，采用不同浓度的水杨酸、硝酸钙、赤霉素预浸种处理，研究其对老化西瓜种子萌发及相关生理生化指标的影响，结果表明：不同处理均可显著提高老化西瓜种子活力，以10mmol/L的Ca(NO3)2处理促进萌发的效果最为明显；不同处理均能明显降低种子浸出液电导率、可溶性糖含量及种子中丙二醛含量，以水杨酸的各处理效果最好。

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.

研究了用甲醇-四氢呋喃-水作为流动相，从C18柱上分离和测定羟苯甲酮-5-磺酸(MS40)、水杨酸钠、水杨酸苯酯、羟苯甲酮(M40)、对-二甲酸氨基苯甲酸-2-乙基己酯(6007)、4-叔丁基-4-甲氧基二苯甲酸甲烷(1789)、对-甲氧基肉桂酸-2-乙基己酯、水氧酸-2-乙基己酯(587)等8种紫外线吸收剂的色谱条件，建立了用HPLC测定上述物质的方法。

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。

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。

When the molar ratio of tungstic acid∶acidic organic additive∶cyclohexene∶ hydrogen peroxide was 1∶1∶40∶176 (tungstic acid, 2.5 mmol) and the tungstic acid/resorcinol used as catalyst, the isolated yield of adipic acid was up to 90.9% for 8 h.

当使用磺酸水杨酸、草酸、水杨酸为有机酸性添加剂时，随反应时间的增加，己二酸分离产率均升高，但反应 6 h 以后，己二酸分离产率随时间的变化不明显。当磺酸水杨酸用量为 2.5 mmol 时，己二酸分离产率和纯度均较高。
