Graphical presentation of repairing potential of PELE against the toxicity of CCl₄ in lungs of rat. a Catalase activity level, b Superoxide dismutase activity level, c Glutathione peroxidase activity level in pulmonary samples of rat. I; Control (untreated group), II; vehicle treated group, III; CCl₄ treated group, IV; CCl₄ + silymarin (100 mg/kg), V; CCl₄ + PELE (200 mg/kg), VI; CCl₄ + PELE (400 mg/kg), VII; PELE (400 mg/kg). Each value corresponds to mean ± SD (n = 3). Bars with different letters indicate significance at P < 0.01
