title: Protecting effect of phytoncide solution, on normal human dermal fibroblasts against reactive oxygen species.
abstract: Four types of phytoncide solutions (A-Type, AB-Type, D-Type and G-Type) was evaluated for reduction of cell damage induced by oxidative stress, ultraviolet A (UVA), ultraviolet B (UVB), hydroxyperoxide (H2O2) and t-butyl-hydroperoxide (t-BHP); stimulation of collagen synthesis against UVA irradiation; and inhibition of matrix metalloproteinase-1 (MMP-1) activity induced by UVA in human normal dermal fibroblasts and human reconstituted skin model. The A-Type, AB-Type, D-Type and G-Type of phytoncide solutions pretreatment resulted in significant protection against cell damage induced by UVB, UVA, H2O2 and t-BHP. The amount of type I collagen following UVA irradiation was increased by treatment with phytoncide solutions in a concentration-dependent manner. On the other hand, phytoncide solutions also suppressed the excess MMP-1 irradiated UVA in a concentration-dependent manner. These effects of G-type solution were superior to those of other types solutions.
