Comparison of the antioxidant-oxidant balance between young and old rats
| Glomeruli | TIS samples | |||
|---|---|---|---|---|
| Young rats | Old rats | Young rats | Old rats | |
| Superoxide anion generation (counts (min mg)−1× 103) | 30 ± 14 | 24 ± 7 | 3 ± 1 | 17 ± 7 * |
| NADH oxidase (counts (min mg)−1× 106) | 94 ± 14 | 93 ± 7 | 135 ± 26 | 115 ± 22 |
| NADPH oxidase (counts (min mg)−1× 106) | 47 ± 5 | 45 ± 3 | 59 ± 28 | 48 ± 14 |
| Total SOD (units mg−1) | 20 ± 3 | 23 ± 5 | 90 ± 22 | 52 ± 9 ** |
