摘要
对兰州地区4至10月龄的新鲜胎尸568例中的1136个肾脏进行了观察。结果表明,胎儿的肾脏是分叶的,肾叶的形状、大小和数量有较大差异。其分叶的数目,从4月龄到10月龄,先是逐渐地增多,以后逐渐减少,形成一个倒“U”字形。因此,胎肾的增长可能有两种方式:一是随肾叶体积的增大而增长;另外除肾叶体积增大外,肾叶的数目也逐渐增加,但随着胎龄的增长,肾叶却有融合的趋势,故数目又逐渐减少,并且胎肾的增长以这种方式为主。
The observation of 1136 fetal kidney, in 568 fresh abortive fetus ranging inages from 4 to 10 months in Lanzhou shows that the fetal kidneys are dividedand there is a big difference in shape, size and the number of the lobi renales.The number of the lobi renales increases gradually, and lessens gradually from 4to 10-month ages, resulting ihthe inversion of the letter 'U' in form. Theremay be two ways in the growth of the fetal kidney: one is that it increases inthe wake of the size; the other is that the number of the lobi renales increasesgradually with the growth of the size of the lobi renales. The lobi renales mergetogether gradually in the wake of the growth of the fetal age, and the numberof the lobi renales lessens gradually. This is the main way of the growth offetal kidney.
