Abstract

The healthy Kunming mice were subjected to investigate SMP can protect the skin against the damage of the irradiation or not. The mice were randomly divided into five groups, in all groups but Normal group were irradiated by long-term ultraviolet. At the same time, the mice in Modal group were smeared distilled water, in Vc group were smeared Vc, and in SMP low-dose and SMP high-dose groups were smeared SMP on the skiu, 15% and 30% respectively. After irradiation, the dorsal skin of animals were analysed by computer imaging analysis system. The results show that the mice in model group, the skin stigmata are coarse, deepening wrinkles, the epidermis became hyperplaatic and skin thickened, however, in SMP high-dose group, the skin of the mice has no significant wrinkles, close to the Normal group. As well, SMP high-dose can significantly decrease the amounts of MDA and increase the content of HYP in the skin (P < 0.01). SMP have the protective effect on the skin of long-term ultraviolet irradiated mice.
