Fig. 3. Effect of dietary lipids and food restriction on liver glutathione peroxidase activity in cyclophosphamide treated and untreated mice. Values (mean ± SEM, 3–5 mice/group) with different superscripts are significantly different at p < 0.05. CO = corn oil, FO = fish oil, CTX = cyclophosphamide, AL = ad libitum, FR = food restriction.
