IgG-subclass concentrations were determined in cord sera from 47 premature, 59 full-term, and 29 small-for-dates babies of varying gestational age. In permature and full term babies the relative percentages of all four subclasses were in the range for normal adult values. However, in small-for-dates babies significantly lowered IgG1-levels were found.
测定了47例早产、59例足月以及29例不同胎龄小于胎龄儿的脐带血清中IgG亚类浓度。早产和足月婴儿中,所有四个亚类的相对百分比均在正常成人值范围内。然而,在小于胎龄儿中发现IgG1水平显著降低。
