Amniotic Fluid Epidermal Growth Factor and Fetal Pulmonary Maturation / 上海第二医科大学学报

ABSTRACT

Objective To evaluate the relationship between amniotic fluid (AF) epidermalgrowth factor (EGF) concentration and fetal pulmonary maturation. Methods Lecithin － sphin-gomyelin ratio (L/S) and EGF were measured in amniotic fluid from women(n = 138,21～42 weeks'gestation) undergoing amniocentesis by TLC and RIA. ResultsThe AF L/S ratio and EGF concen-tration increased linearly with Gestational age(GA) ( r = 0.8t3 and 0.87, respectively, P < 0.01 ).There was a strong correlation between the AF L/S ratio and EGF( r = 0.76, P < 0. 001 ). Conclu-sionThere are a confirmed relationship between AF EGF levels and fetal pulmonary maturation.
