title: [Effects of intrapartum steroid prophylaxis on complement C3 and total complement activities (author's transl)].
abstract: One single high dose of dexamethasone (0.5 mg/kg body weight) was administered to a mother, before tests started into the effects of such approach upon the serum total complement (CH 50) and C-3 levels in the mother's umbilical cord blood. Neither CH 50 nor C-3 complement had declined with significance 48 hours from steroid administration. Significant reduction was observed only in cases in which six hours elapsed between steroid administration and childbirth.
