Abstract：
:The effects of glucocorticoids on primate fetal lung function have not been clearly delineated. In this prospective study of preterm rhesus fetuses exposed in utero to betamethasone for 72 hours, the most significant alteration was a striking increase in maximum lung volumes. Functionally less significant increases in residual lung volumes were also noted. The lungs of the treated fetuses did not exhibit lower extract surface tensions or increased phospholipid concentrations. These findings suggest that the major effect of betamethasone is on lung connective tissue elements, with minimal effects on alveolar surfactant. Additional evidence of the multisystemic effects of glucocorticoids was obtained in that significant differences in fetal, adrenal, hepatic, and placental weights also were observed.
