[Effect of modified Yupingfeng granule on nuclear factor-kappaB expression in mice with allergic contact dermatitis].

OBJECTIVE

To investigate the effect of modified Yupingfeng granule on nuclear factor-kappaB (NF-kappaB)expression in mice with allergic contact dermatitis (ACD).

METHODS

Mouse models of ACD were treated with the granules at low, medium and high doses, with normal saline and hydrocortisone as the negative and positive controls, respectively. The expressions of NF-kappaB and its distribution in the lesions were detected using immunohistochemistry.

RESULTS

The staining intensity, area and positive expression rates of NF-kappaB p50 were significantly different between the treatment group and the normal saline group (P<0.05).

CONCLUSION

Modified Yupingfeng granule can effectively inhibit the expression of NF-kappaB in ACD, which might be a possible mechanism for its therapeutic effect on ACD.
