[Oligo-elements of the amniotic fluid from normal, hypotrophic and trisomy 21 fetuses].

Oligo-elements concentrations were measured between 16-18 weeks of normal pregnancy in the amniotic fluid of 84 women who delivered children with a normal weight, 16 women who had term delivery of hypotrophic children, and 7 women who delivered trisomic children (5 trisomy 21, one trisomy 18 and one trisomy 10p). Copper, zinc, bromine, lead, rubidium assays were carried out using fluorescence X spectrophotometry with dispersion of energy. The oligo-elements levels are not different in the three groups of amniotic fluid: hypotrophic, trisomic or normal fetuses. These results are compared with those previously reported.
