Abstract:
Objective: To observe the analgesic and anti-inflammatory effect of mandelic acid. Methods: Fifty Kunming mice were randomly divided into 5 groups:the blank control group (0. 1 ml/10 g), mandelic acid high (300 mg·kg-1), medium (200 mg ·kg-1 ) and low (140 mg·kg-1 ) dose groups, and the positive control ( aspirin) group, ig, qd. The analgesic effect of mandelic acid was observed by writhing test and hot plate method in mice. The ear swelling model caused by dimethyl benzene in mice was a-dopted to observe the analgesic effect. Results:Mandelic acid in each dose group could make the number of writhing in mice signifi-cantly reduced and pain threshold extended, and when compared with the blank control group, the difference was statistically significant (P<0. 01). The writhing times of mice mandelic acid high dose group was fewer than that of the positive control group, and there was no statistically significant between the groups (P>0. 05). In low and medium dose group, the writhing times of mice were more than those of the positive control group, and there was a significant difference between the low dose group and the positive control group( P<0. 05). The pain threshold of the mice in each mandelic acid dose group was higher than that of the positive control group, the pain threshold increased significantly in the high dose group before and after the administration, and the difference was statistically signifi-cant when compared with the positive control group (P<0. 05). The effect of mandelic acid on the ear swelling of mice was not signifi-cant, and when compared with the blank control group, the difference was not significant (P>0. 05). Conclusion:Mandelic acid has significant analgesic effect, while anti-inflammatory effect is not obvious.
