Table 1.
Placental MDA and TAC levels throughout normal gestation.
| Groups | N | MDA | TAC | Age |
|---|---|---|---|---|
| (pmol/mg tissue) | (μmol Trolox equivalent/mg tissue) | (yrs) | ||
| First trimester | 106 | 277.01 ± 204.66 | 498.62 ± 400.74 | 26.77 ± 6.27 |
| Second trimester | 48 | 202.66 ± 185.05 | 454.90 ± 374.44 | 25.87 ± 6.50 |
| Third trimester | 47 | 176.97 ± 141.61 | 912.19 ± 586.21 | 26.83 ± 6.33 |
MDA: malondialdehyde; TAC: total antioxidant capacity. Data expressed as mean ± SD.
Placental MDA levels were highest in the first trimester and progressively declined thereafter, while TAC levels showed a significant increase beyond the second trimester of normal pregnancy.
