Mean ± SE (n = 6 mice/group). One hundred percent for vitamin E, GSH and MDA corresponds to 0.1 nmol/mg protein; 22 nmol/mg protein and 0.3 nmol/mg protein, respectively. *p<0.05, vs mice given basal diet and aspirated with PBS, #p<0.05, vs mice given vitamin E-deficient diet and aspirated with PBS, §p<0.05, vs mice given basal diet and aspirated with SWCNTs.
