Abstract To obtain a comprehensive profile of the erythrocyte antioxidant defense potential during aging, we investigated copper-zinc superoxide dismutase (CuZn-SOD), seleno-dependent glutathione peroxidase (GSH-Px), glutathione reductase (GSSG-RD), and glutathione-S-transferase (GSH-S-T) activities in human erythrocytes from 167 apparently healthy subjects, ages one month to 63 years (102 females, 65 males). We found a negative correlation between age and activities of CuZn-SOD (r = 0.362, P less than 0.001), GSSG-RD (r = 0.549, P less than 0.001), and GSH-S-T (r = 0.575, P less than 0.001). In contrast, we found a positive correlation between age and GSH-Px activity (r = 0.401, P less than 0.001). To evaluate aging changes, we divided the subjects into five groups: Group 1 (newborn-age one year), Group 2 (1-11 years), Group 3 (11-25 years), Group 4 (25-40 years), and Group 5 (40-63 years). Significant age-related modifications in erythrocyte enzyme activities appeared in Group 3 for CuZn-SOD, GSSG-RD, and GSH-Px activity, whereas for GSH-S-T activity age-related modifications appeared in Group 2. We found no sex-related differences in erythrocyte CuZn-SOD, GSSG-RD, GSH-Px, and GSH-S-T activities. © 1992 The American Association for Clinical Chemistry « Previous | Next Article » Table of Contents This Article Clinical Chemistry January 1992 vol. 38 no. 1 66-70 » Abstract PDF Services Email this article to a friend Alert me when this article is cited Alert me if a correction is posted Similar articles in this journal Similar articles in Web of Science Similar articles in PubMed Download to citation manager Responses No responses published Citing Articles Load citing article information Citing articles via Web of Science Citing articles via Google Scholar Google Scholar Articles by Ceballos-Picot, I.
