Effects of MPEO on the hepatic antioxidant profile in CCl₄-induced liver fibrosis.

Experimental groups	GSH (μM/g liver)	SOD (U/mg protein)	CAT (U/mg protein)	TAC (μmol/g liver)
Group 1	12.48 ± 0.32^a	82.95 ± 2.56^a	2.15 ± 0.07^a	5.24 ± 0.25^a
Group 2	2.93 ± 0.14^b	20.29 ± 1.13^b	0.93 ± 0.06^b	2.08 ± 0.16^b
Group 3	4.8 ± 0.19^c	47.6 ± 1.22^c	1.37 ± 0.05^c	3.88 ± 0.12^c
Group 4	11.6 ± 0.31^a	72.45 ± 2.10^a	1.94 ± 0.04^a	4.30 ± 0.22^a

Group 1: normal control; group 2: liver fibrosis control; group 3: MPEO-treated; group 4: MPEO control. Values are expressed as mean ± SE. Different superscripts mean significant differences between groups in the same column at . GSH: reduced glutathione; SOD: superoxide dismutase; CAT: catalase; TAC: total antioxidant capacity.
