A Preliminary Study on Anti-inflammatory and Analgesic Effects of Millettia speciosa and Tinpspora sinensis and Their Compatibility

[Objectives]To study the anti-inflammatory and analgesic effects of Millettia speciosa and Tinpspora sinensis and their compatibility.[Methods](i)In the glacial acetic acid writhing experiment,60 SPF-grade Kunming mice were adopted,and the mice were randomly divided into 6 groups at male-female ratio of 1∶1,namely,the blank control group,M.speciosa group,T.sinensis group,M.speciosa compatible with T.sinensis group at the ratio of 1∶2(expressed as 1∶2 compatibility group),M.speciosa compatible with T.sinensis group at the ratio of 1∶1(expressed as 1∶1 compatibility group),and M.speciosa compatible with T.sinensis group at the ratio of 2∶1(expressed as 2∶1 compatibility group),12 mice for each group.Mice of the experimental groups were administered at a dose of 20 mL/kg,and the corresponding concentration of the Chinese medicine extract was given at 1 g/mL.The control group was administered with an equal volume of 0.9%physiological saline,and was intragastrically administered once every 24 h for 14 d.After intragastric administration for one hour on day 14,intraperitoneal injection of 0.5%glacial acetic acid solution was performed to induce pain.(ii)In the hot plate experiment,60 Kunming female SPF mice were adopted,grouped,intragastrically administered with the same glacial acetic acid writhing experiment for 14 d.After intragastric administration for one hour on day 14,the mice were placed on a hot plate apparatus at(55±0.5)℃.to measure the time of licking their hind feet.(iii)In the anti-inflammatory experiment,60 Kunming SPF mice were adopted,grouped,intragastrically administered with the same glacial acetic acid writhing experiment for 14 d.After intragastric administration for one hour on day 14,xylylene was administered to the left ears of mice at a dose of 50μL/piece to induce inflammation.[Results](i)In the glacial acetic acid writhing experiment,compared with the blank control group,the experimental group showed analgesic effects.Specifically,M.speciosa group,T.sinensis group,1∶2 compatibility group,1∶1 compatibility group,2∶1 compatibility group showed significant effect(P<0.05),the writhing inhibition rate was 17.65%,20.59%,29.41%,26.47%,and 44.12%,respectively,and 2∶1 compatibility group showed the most significant analgesic effects.(ii)In the hot plate experiment,compared with the control group,all experimental groups showed analgesic effect.Specifically,M.speciosa group,T.sinensis group,1∶2 compatibility group,1∶1 compatibility group,2∶1 compatibility group showed significant effect(P<0.05),the pain threshold improvement rates were 16.13%,14.55%,14.96%,29.95%,and 58.68%,respectively,and 2∶1 compatibility group showed the most significant analgesic effect.(iii)In the anti-inflammatory experiment,the swelling degree of the 1∶2 compatibility group was significantly different from that of the blank control group,M.speciosa group,T.sinensis group(P<0.05).and 1∶2 compatibility group showed the most significant anti-inflammatory effect.[Conclusions]M.speciosa,T.sinensis,and their compatibility had anti-inflammatory and analgesic effects.The 2∶1 compatibility group had the best analgesic effects,and 1∶2 compatibility group had the best anti-inflammatory effects.
