肺表面活性物质在胎儿生后可促进一种生理功能,使肺泡稳定。表面活性物质在胎儿期发育成熟。若未成熟儿生后其合成不足,就发生呼吸艰难综合征,此病征是新生儿死亡的主要原因。但是对肺表面活性物质在发育上的生物合成,特别是对胎儿及新生儿表面活性物质 Pulmonary surfactant promotes a physiological function after birth and stabilizes the alveoli. Surfactants mature during the fetal period. If immature synthesis after their lack of synthesis, respiratory distress syndrome occurs, the disease is the main cause of neonatal death. However, the development of pulmonary surfactant in the development of biosynthesis, especially for fetal and neonatal surfactant
