Abstract

The present study was conducted to investigate the effect of Gamisamul-tang (GSMT) on atopic dermatitis (AD). AD was induced in NC/Nga mutant mice by DNCB treatment. GSMT administration reduced levels of skin severity scores. Serum levels of IgE, IgG, IgM, and inflammatory cytokines including IL-4, IL-4 and 1L-13 were significantly decreased by GSMT treatment. Levels of mRNA's encoding IL-4, IL-6, IL-13, $TNF-{\alpha}$, and $interferon-{\gamma}$ in the dermal tissue and draining lymph node (DLN) by real time RT-PCR analysis showed decrease by GSMT testament. Moreover, the number of CD4+ and CD8+ cells was significantly decreased in the spleen and DLN tissues. Histological examination showed that infiltration levels of immune cells in ear, skin, and DLN of AD-induced NC/Nga mice were much improved by GSMT treatment. The present data suggest that GSMT may play an important role in recovering AD symptoms by regulating immune reactivity.
