Abstract
The human fetal birth weight does not scale linearly with the weight of the placenta, but exhibits an allometric scaling consistent with Kleiber's Law for the basal metabolic rate. We discuss the possible causes of such scaling, and its clinical consequences. In particular, we show that the value of the scaling exponent is an indicator of a normal fetoplacental development.
摘要
人类胎儿出生体重与胎盘重量并非呈线性比例关系，而是呈现出与克莱伯定律（关于基础代谢率）相一致的异速生长比例关系。我们讨论了这种比例关系的可能成因及其临床后果。特别地，我们表明比例指数的值是胎儿胎盘正常发育的一个指标。
