Plasma immunoreactive endothelin-1 (ir-ET-1) concentrations in cord blood of 20 term
infants were measured by radioimmunoassay. The mean (± SEM) ir-ET-1 concentration
was 1.04 ± 0.29 pg/mL There was no relationship between ir-ET-1 concentrations and
race, sex, mode of delivery, and prenatal characteristics, such as cocaine exposure.
The current methodologies were reviewed in an effort to explain the differences in
ET-1 concentrations reported in various studies.
