Atopic dermatitis (AD) is chronic relapsing skin inflammatory allergic disease characterized by a complex pathogenesis including skin barrier dysfunction, immune-redox disturbances and pruritus. Topical treatment medications such as corticosteroids, calcineurin inhibitors, T-cell inhibitors were used in AD but these agents may have some potential side-effects. Therefore, many researchers explored abundant numbers of alternative therapies by using natural products and mineral compounds related with its antioxidant and immunomodulator effects to minimize toxicity and adverse-effects. In the present study, we investigated the effects of mineral complex material patch (MCM) treatment on AD-like lesions in 2, 4-dinitrochlorobenzene (DNCB)-induced hairless mice. Animals were divided into four groups; normal control, negative control (DNCB Only), DNCB+ Tacrolimus (PC) and DNCB+MCM patch to evaluate its therapeutic effect on DNCB-induced AD. Our results showed that MCM patch improved the skin dermatitis by significantly increasing the skin barrier strength, score and moisture level and decreasing the transepidermal water loss as compared to DNCB only group. In line, ROS level, inflammatory, Th1 and Th2 cytokines were decreased with MCM treatment whereas nitric oxide level and total anti-oxidant enzyme activities were significantly enhanced as compared to DNCB only and NC groups. Moreover, total IgE level was significantly increased in DNCB only group and decreased in PC and MCM treated group. Taken together, our findings suggest that MCM may potentially protect against AD lesional skin via regulation of skin barrier function and immune-redox response. However, further studies are needed to explain the detail molecular mechanism of MCM effect.
