Competitive effect of hydrogen peroxide (H2O2) (10 nM) versus EGCG (50 µg/ml) on the SOD and GPx activities in HeLa cell line after 24 hr

S. No. SOD GPx
Hela 40.87 ±0.91 40.76 ±1.60
Hela + H2O2 19.35 ±1.139
(–52.57 %)		 17.04 ±1.47
(–58.19 %)
Hela + H2O2 +EGCG 45.58 ±1.28
(+135.55 %)		 54.79 ±1.37
(+221.53 %)

Values are expressed as Mean ± SEM of 5 experiments; the value in parentheses shows the percentage decrease and increase with respect to the control. The level of significance was p < 0.05
