) protein levels in samples of liver tissue were determined by western blot analysis from control rats, carbon tetrachloride (CCl~0~)-treated rats, CCl~0~ plus naringenin rats (CCl~0~ + NAR), and rats administered with NAR alone (NAR). β-actin was used as a control. Values are expressed as fold increase of relative IOD normalized to the control group values (control = 0). Each bar represents the mean value of three rats ± SE. ^a^*P* \< 0.00 *vs* control group; ^b^*P* \< 0.00 *vs* CCl~0~ group.](WJG-00-0000-g000){#F0}
