阿司匹林-烟酰胺-锌络合物镇痛抗炎作用的实验研究

Experimental studies on analgesic and anti-inflammation effects of aspirin -niacinamide-zinc complex (WUY)

目的 :对阿司匹林 烟酰胺 锌络合物 (WUY)的镇痛和抗炎作用进行初步研究。方法 :采用小鼠耳廓肿胀、腹腔毛细血管通透性增加以及大鼠足跖肿胀法研究抗炎作用 ,小鼠热板法和扭体法研究镇痛作用。结果 :WUY中、高剂量组的耳廓肿胀度分别为 3.3和 2 .8mg ,伊文思蓝渗出量分别为 3.1和1.2mg·L-1,足跖肿胀度 (1～ 4h)分别为 0 .2 1～0 .13和 0 .2 3～ 0 .0 8ml。小鼠热板法可明显延长热痛反应潜伏期 ,提高小鼠的痛阈值。醋酸扭体法显示WUY对小鼠扭体反应次数有明显抑制作用 ,且比阿司匹林 (ASP)强。结论 :WUY具有比ASP更强的镇痛和抗炎作用。

AIM: To study the analgesia and anti-inflammation effects o f aspirin-niacinamide-zinc complex (WUY). METHODS: In this study , the mice ear swelling, vascular permeability increasing and rats’ paw edema w ere adopted to evaluate the anti-inflammable effects of WUY. And the analgesic effects of WUY were tested by writhing reaction and hot-plate method. R ESULTS: In high and low dose groups of WUY, the degrees of ear swelling were 3.3 and 2.8 mg, the Evans blue induced effusion were 3.1 and 1.2 mg·L -1, and the paw edema volume (1-4 h) were 0.21- 0.13 and 0.23- 0.08 ml, respectively. WUY ( 0.3 and 0.45 mmol·kg -1) prolonged incubation period of hot-plate reaction and showed marked i nhibition effects on writhing induced by acetic acid in mice. CONCLUSION : The analgesic and anti-inflammable effects of WUY are stronger than t hat of ASP.
