Figure 2: Effect of oral administration of n-acetylcysteine on the brain level of GSH in doxorubicin-induced neurotoxicity in rats. Each value represents the mean ± SE. Data were analyzed by one-way ANOVA followed by Tukey post hoc test. NAC = n-acetylcysteine, DOX = doxorubicin, DOX+NAC1 = DOX+NAC treated group 1, DOX+NAC2 = DOX+NAC treated group 2. *Significant difference at P < 0.05 Vs. Control group. aSignificant difference at P < 0.05 Vs. DOX-treated group. •Significant difference at P < 0.05 Vs. DOX+NAC2 treated group.
