Comparison of the brain weight/liver weight ratio(1) with the body weight of 95 stillborn and neonatally deceased infants of gestation 25-42 weeks shows that in appropriately grown infants the mean value ratio is 2.8 and is unchanged with increasing maturity. The normal range is 1.7-4.1. Survival time has no significant effect on the ratio as studied in this necropsy population. Dysmature infants of body weight less than 1 SD below the mean body weight for gestation are characterized by a brain: liver weight ratio of 4.5 or more. On the basis of these observations the brain: liver weight ratio may be employed as a guide to the prenatal nutrition of infants at necropsy.
对95例孕25 - 42周死产及新生儿期死亡婴儿的脑重/肝重比(1)与体重进行比较,结果显示,在发育正常的婴儿中,该比值的平均值为2.8,且不随成熟度增加而变化。正常范围为1.7 - 4.1。在该尸检人群中研究发现,存活时间对该比值无显著影响。体重低于同孕周平均体重1个标准差的发育不成熟婴儿,其脑:肝重比为4.5或更高。基于这些观察结果,脑:肝重比可作为尸检时评估婴儿产前营养状况的一项指标。
