Group	SOD	Catalase	GSH-Px
	(U/mg protein)	(U/mg protein)	(U/mg protein)
Sham operation	31.82 ± 2.29	255.3 ± 35.0	138.7 ± 10.3
LPS plus ischemia-reperfusion
Control	16.67 ± 2.52^c	146.8 ± 19.3^c	79.5 ± 7.2^c
(−)-Epicatechin 3-O-gallate (10 𝜇moles/kg B.W./day)	18.18 ± 1.70^c	176.0 ± 15.3^c	105.7 ± 8.0^c,e
