Objectives: The purpose of this study is to investigate the suppressive effects of Atopy cream-combined with Jawoongo ointment (A-J), on the development of atopic dermatitis-like skinlesions in NC/Nga mouse.
Methods: We evaluated clinical skin score, hematology and Serum total IgE and IgG1 of NC/Nga atopic dermatitis mouse, analyzed the cytokine level, total cell number, Immunohistochemical staining and Histological features of axillary lymph node(ALN), draining lymph node(DLN), peripheral blood mononuclear cells(PBMCs) and dorsal skin tissue in NC/Nga mouse.
Results: A-J decreased the clinical skin score, total cell number of WBC, platelet, neutrophils, eosinophils in blood, Serum total IgE & IgG1, IL-5, IL-13. Also, total cell number of ALN and dorsal skin tissue, Absolute cell number of &, &, , , , in ALN, PBMCs, Absolute cell number of , , in dorsalskin tissue, Eotaxin2 mRNA, CCR3 mRNA in dorsal skin tissue and gene expression of IL-5 mRNA, IL-13 mRNA in ALN decreased significantly. Furthermore, thickness of epidermis, infiltrated inflammatory immune cell and mast cell in dermis, histologic infiltration of mast cell, the size of inflammatory lymphocytes cells and plasma cells in ALN and histologic infiltration of CD4+ & CCR3+ in ALN and dorsal skin tissue decreased significantly. However, total cell number of DLN, absolute cell number of &, &, , increased significantly.
Conclusions: A-J was the successful treatment of atopic dermatitis in a NC/Nga mouse model.
