Effects of cell viability and antioxidant enzyme activity of Phellinus linteus extract on Mouse melanoma cells(B16F10)

The effects of oxidative stress on the alterations of different antioxidant enzyme activity on mouse melanoma cells(B16F10) was investigated. Oxidative stress was induced by the exposeure to hydrogen peroxide(H2O2). B 16F 10 cells were exposed Phellinus linteus Ex. in combination with H2O2 and measured the time course of changes in cell viability and antioxidant enzyme activity. CAT activity peaked at 12 hr. On the contrary, SOD and GPX activity was maximum at 6 hr. The cell viability of Pheltinus linteus extracts in combination with hydrogen peroxide was higher than hydrogen peroxide alone.
