摘 要: | 目的:观察不同剂量的洛贝林对氯胺酮镇痛作用的影响。方法:80只昆明钟小鼠按试验方法的不同平均分为两大组:40只用于甩尾法试验,另40只用于扭体法试验。各组再随机分为4个小组,即氯胺酮与生理盐水合用组(KN组)及氯胺酮分别与洛贝林1mg/kg合用组(KL1组)、氯胺酮分别与洛贝林2mg/kg合用组(KL2组)、氯胺酮分别与洛贝林3mg/kg合用组(KL3组),用热水甩尾法和扭体法观察不同剂量洛贝林对氯胺酮镇痛的影响。结果:与KN组相比,KL1、KL2、KL3组小鼠的痛阈(HPPT)显著缩短(P〈0.05),同时,KL2、KL3组小鼠的扭体次数显著增加(P〈0.01)。KL1组与KL组相比则无显著差异。结论:1~3mg/kg的洛贝林可以拮抗氯胺酮的镇痛作用。

Abstract: | Objective: To observe the effect of lobe line on the analgesia by ketamine. Methods: 80 mice were randomly divided into 2 large groups (hotwater tail-flick group and writhing group) ,each of which was further divided into 4 groups with 10 mice in each group: NS plus ketamine group (KN group) ,1 mg/kg lobeline plus ketamine group (KL1 group) ,2 mg/kg lobeline plus ketamine group(KL2 group) ,3 mg/kg lobeline plus ketamine group(KL3 group) . Using tail-flick test and writhing test,the effect of lobeline at different concentrations on the analgesic action of ketamine was observed. Results: The injection of lobeline(1,2 and 3 mg/kg) decreased the HPPT of the mice after injection of ketamine (P〈0. 05) . The injection of lobeline(2 and 3 mg/kg) obviously increased writhing times of the mice after injection of ketamine (P〈0. 01) . But the injection of lobeline (1 mg/kg) had no obvious effect on the writhing times of the mice after injection of ketamine. Conclusions: Lobeline(1 ~ 3 mg/kg) can antagonize the the analgesia by ketamine. |
