目的观察清咽含片的镇痛作用。方法采用小鼠热板法和酒石酸锑钾所致的小鼠扭体反应,观察小鼠的镇痛作用。结果清咽含片可明显提高小鼠痛阈,延长酒石酸锑钾所致扭体发生的潜伏期及减少10min内扭体次数。作用与西瓜霜润喉片大体相当。结论清咽含片具有较好的镇痛作用。
Objective To observe the analgesic effect of Qingyan Lozenge. Methods The mouse writhing response induced by mouse hot plate method and potassium antimony tartrate was used to observe the analgesic effect of mice. Results Qingyan lozenges can significantly increase the pain threshold of mice, prolong the incubation period of writhing caused by strontium tartrate, and reduce the number of writhings within 10 min. The effect is roughly equivalent to watermelon frost lozenges. Conclusion Qingyan lozenge has better analgesic effect.
