Preexposure to Olive Oil Polyphenols Extract Increases Oxidative Load and Improves Liver Mass Restoration after Hepatectomy in Mice via Stress-Sensitive Genes

Figure 2

(a) Superoxide dismutase, (b) catalase, (c) glutathione peroxidase, and (d) glutathione reductase activity in the polyphenols extract treated and untreated hepatectomized mice at different time intervals after hepatectomy. Time zero correspondents to values from the unhepatectomized, vehicle (PSS or PFE) treated mice. Results are the mean ± SD of five to six individual determinations for each experimental point, ; (A) significantly different from the unhepatectomized mice receiving PSS at a given time point; (B) significantly different from the unhepatectomized mice receiving PFE at a given time point; (C) significant difference between PFE treated and untreated hepatectomized mice at a given time point.
