ABSTRACT
The anti-inflammatory activity and compatibility ratio of flavonoids in Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle(GR) and Angelicae Sinensis Radix(AS) were evaluated by the superoxide anion scavenging test. The matrix formula of gel was optimized by orthogonal test design and the model of deep partial-thickness scald in mice was induced. The gel was applied to the wound. The tissue water content, wound healing rate, serum TNF-α and IL-1, and EGF and VEGF in tissues were measured at diffe-rent periods. The results revealed that when the compatibility ratio of GR and AS was 1∶2, the maximal scavenging efficacy on supe-roxide anion was observed. The gel displayed the optimal properties when carbomer(1%), glycerol(5%), propylene glycol(10%) were added into the matrix. Gel external application can significantly improve the wound healing rate, relieve tissue edema, diminish tissue water content, alleviate inflammatory reaction, and increase the content of EGF and VEGF in tissues(P<0.05). The gel prepared in the present study is effective in promoting granulation, relieving pain, resisting inflammation, and alleviating edema, and is potent in healing scalds.
