Amount of α-Tocopherol in the plasma (nmol/L, n=7), liver and brain (nmol/g, n=2 for all and n= 3 for high vitamin E diet at 12 weeks) of 8 and 12 weeks old Xpg−/− mice. Errors represent s.e.m. values. a = compares low with medium vitamin E group; b = medium vs high; c = high vs low; ns: not significant.
