Abstract:In the present study, we investigated the effects of Polygonum tinctoria Niram (PTN) on atopic dermatitis (AD) in BALB/c mice induced by 2,4-dinitrochlorobenzene (DNCB). They were divided into four groups; Control, DNCB, DNCB+1%PTN (1% PTN extract) and DNCB+5%PTN (5% PTN extract), for evaluating the change of appearance of skin surface, skin hydration, thickness of epidermis and mast cell numbers during 4 weeks. PTN suppressed symptoms of AD in appearance of skin and increased skin hydration for DNCB+1%PTN and… Show more
