Abstract

Groups of rats covering a range of ages were deprived of food, water, or both food and water. The percentage weight loss in all groups was found to be well approximated by a simple power function of deprivation time, with the exponent being relatively independent of the age of the animals or the kind of deprivation. However, younger animals lost weight at a faster rate than older ones and were more affected by food deprivation than by water deprivation. Several aspects of the data suggest that young animals are subject to an obligatory growth factor that produces a disproportionately greater debilitation when they are food deprived.

剥夺,体重减轻和大鼠的摄入量作为年龄的函数:强制性生长因子的证据
一组不同年龄的老鼠被剥夺了食物和水,或者食物和水都被剥夺了。所有组的体重下降百分比被发现很好地近似于剥夺时间的简单幂函数,指数相对独立于动物的年龄或剥夺的种类。然而,年轻的动物比年长的动物体重减轻得更快,而且食物匮乏比水匮乏对它们的影响更大。数据的几个方面表明,幼小的动物受到一种强制性生长因子的影响,当它们被剥夺食物时,这种生长因子会产生不成比例的更大的衰弱。
