Abstract

Amnionic fluid (AF) specimens from 40 normal obstetric patients at 14 to 16 weeks' gestation and at 37 to 40 weeks' gestation were found to contain both lysozyme and a bactericidal substance identified as B-lysin. The concentrations of both lysozyme and B-lysin were significantly higher in the AF at 40 weeks' than at 14 weeks' gestation. B-lysin concentration in AF were also found to be significantly higher than in either cord or maternal blood.

摘要

对40例妊娠14至16周以及37至40周的正常产科患者的羊水样本进行检测，发现其中既含有溶菌酶，又有一种被鉴定为B-溶素的杀菌物质。溶菌酶和B-溶素的浓度在妊娠40周时的羊水中显著高于妊娠14周时。还发现羊水中B-溶素的浓度显著高于脐带血或母血中的浓度。
