摘要
目的:分析赤雹果水提取物镇痛作用与阿片受体的关系。方法:采用小鼠浸尾法(45℃)、热板法(48℃)观察赤雹果水提取物(WEFTD)的镇痛作用及纳络酮对其镇痛作用的影响。结果:4.0g/kg WEFTD可显著提高小鼠浸尾法和热板法的痛阈值,与药前比较差异显著(P<0.05),纳络酮+WEFTD组与WEFTD组痛阈值差异无显著意义(P>0.05);纳络酮+吗啡组痛阈显著低于吗啡组(P<0.01)。结论:WEFTD的镇痛作用不是由阿片受体介导的。
Objective:To observe the relationships between the opiate receptor and the analgesic effects of the water extract of Thladiantha Dubia fruits (WEFTD).Methods:The analgesic effects of WEFTD and the influence of Naloxone were evaluated by tail-immersion test (45℃) and hot-plate test (48 ℃ )in mice.Results: 4.0g/kg WEFTD could markedly heightened the pain threshold in tail-immersion test and hot-plate test in mice (P 〈 0.05).There had no significant difference between the pain threshold of 4.0g/kg WEFTD and that of Naloxone+WEFTD (P 〉 0.05).The pain threshold obviously diminished in morphine+Naloxone group than morphine group (P 〈 0.05).Conclusions:The analgesic effect of WEFTD is not mediated by opiate receptor.
