Abstract:
OBJECTIVE:To investigate the anti-inflammatory and analgesic effects of mongolian medicine Cymbaria dahurica extract. METHODS:96 KM mice(or SD rats)were randomly divided into model group(water),positive control group(aspirin, 0.5 g/kg),C. dahurica ethanol extract (70% ethanol) low-dose,medium-dose and high-dose groups (0.325,0.650,1.300 g/kg, calculated by crude drug) and C. dahurica aqueous extract of the residue of alcohol extraction low-dose, medium-dose and high-dose groups(0.325,0.650,1.300 g/kg,calculated by crude drug). They were given relevant medicine intragastrically,once a day,for consecutive 7 d. The xylene-induced ear edema method was used to determine the degree of ear edema,and egg white-in-duced paw edema method was used to determine paw edema after inducing inflammation 1,2,4,6 h;anti-inflammatory activity of C. dahurica extract was investigated. 96 KM mice were grouped and given medicine with same method;the number of writhing within 20 min was determined by acetic acid writhing method. Another 64 KM mice were grouped with same method,with 8 mice in each group;except positive control group was given tramadol hydrochloride(0.5 g/kg)intragastrically,other groups were given relevant medicine with same method. Pain thresholds of mice were determined by hot-plate test before and after medication 30,45, 60,90 min,and analgesic effects of C. dahurica extract were investigated. RESULTS:Compared with model group,C. dahurica extract could obviously restrain the ear edema of mice and paw edema of rats 6 h after egg white-induced inflammation. Except paw edema of rats in C. dahurica aqueous extract of the residue of alcohol extraction high-dose group was decreased slightly,there was statistical significance among other groups (P<0.05 or P<0.01). C. dahurica extract decreased the number of writhing in mice within 20 min,and extended pain thresholds of mice 30,60,90 min after medication (P<0.05). CONCLUSIONS:Both C. dahurica ethanol extract and aqueous extract of the residue of alcohol extraction posses certain anti-inflammatory and analgesic effects.
