摘      要：Objective:In this study,we examined the effects of Shizhenqing granule(SZQG)on hypothalamicpituitary-adrenal(HPA)axis and serum inflammatory factors in a rat model of chronic eczema,in order to explore the mechanism of action of SZQG in treatment of this ***:Sixty SpragueeDawley male rats were randomly divided into six groups(with 10 rats per group):blank group;model group;positive control group(prednisone);and the low-,medium-,and high-dose SZQG *** for the blank group,rats in all other groups were treated with 2,4-dinitrochlorobenzene to induce chronic *** rats were administered prednisone or SZQG for 7 consecutive days after successful establishment of the chronic eczema model,and samples were collected 12 h after the last *** degree of skin lesions and the changes in serum levels of corticotropin-releasing hormone(CRH),adrenocorticotropic hormone(ACTH),cortisol(CORT),interleukin(IL)-4,interferon(IFN)-g,IL-25,and IL-31 among the groups were ***:SZQG effectively increased the levels of CRH,ACTH,and CORT,which decreased in the serum of rats with chronic eczema,stimulated the function of the HPA axis,and promoted the expression of *** reduced the serum levels of inflammatory factors including IL-4,IL-25 and IL-31,which were overexpressed in rats with chronic eczema,and increased those of anti-inflammatory factor IFN-g,thereby alleviating the inflammatory symptoms and itching,and ameliorating the clinical symptoms of chronic ***:SZQG effectively alleviates skin lesions in the chronic eczema rat model by stimulating the function of the HPA axis.
