RESUMEN
Alpha-tocopherol level was measured spectrofluorometrically in 279 healthy volunteers to establish reliable reference values and to compare possible sex and age-related differences. In the present study, men had higher tocopherol levels than women (p<0.05) and older subjects had lower values. This study provides reference values for alpha-tocopherol that may assist it evaluating the anti-oxidant defense.

We measured lipoperoxides, as malonaldehyde (MDA) by thiobarbituric acid reaction in serum from 80 male and 120 female volunteers to establish reliable reference values and to compare possible sex- and age- related differences. In the present study women had higher MDA concentration in serum than do men (p<0.05) and older subjects had higher values (p<0.05). These age related results support the suggestions that lipid peroxidation increases with increasing age.
