Objectives :This study aimed to find the curative effect of Gamitongkyutang distillate in mice with allergic rhinitis.
Metbods :Forty mice were divided into four groups: the normal group, the control group (allergic rhinitis elicited group), the sample I group (Gamitongkyutang treated group after allergic rhinitis elicitation) and the sample II group (distillate of Gamitongkyutang treated group after allergic rhinitis elicitation). Indexes of AR were investigated such as the histological changes of the nasal mucosa, the changes of eosinophil count, the changes of interleukin-4(IL-4) secretion in the intranasal mucosa, the alteration of inducible nitric oxide synthase(iNOS) mRNA expression and the distribution of the nuclear factor kappa B (NF-kB). ANOVA test was used for statistical analysis (p<0.05).
Results :Loss of the cilium and the mucous secretion in the sample I and II groups was rare when compared to the control group. The segment of eosinophil was significantly decreased in the sample I and II groups when compared to the control group (p<0.05). A significant decrease of IL-4 mRNA expression was observed in the sample I and II groups when compared with the control group (p<0.05). Inhibition of iNOS induced by NF-kB p50 in the sample I and II groups was significantly superior to that in the control group (p<0.05). DGT and GT didn’’t affect AST and ALT.
Conclusions :GT was superior to DGT in the IL-4 secretion, eosinophil levels and iNOS production. However, considering the difficulty in taking herbal medicine, the DGT has a meaningful curative effect in mice with allergic rhinitis.
