PLASMA AND ERYTHROCYTE ZINC AND BIRTH-WEIGHT IN PREECLAMPTIC PREGNANCIES

Plasma and erythrocyte zinc concentrations in 45 proteinuric pre-clamptic Chinese women were measured. There was no difference in either the plasma or erythrocyte zinc concentration between pre-eclamptic patients with and without intrauterine growth retardation. There was no correlation between either plasma or erythrocyte zinc concentration with the gestation at delivery, birth weight, mean arterial pressure and plasma albumin concentration. On the other hand, both plasma albumin concentration and mean arterial pressure were significantly correlated to birth weight, and the mean arterial pressure was also significantly higher in patients with intrauterine growth retardation. Plasma and erythrocyte zinc are not useful as indices of severity in pre-eclampsia. © 1990 Springer-Verlag.
