小儿肺的年龄解剖学研究

ANATOMICAL OBSERVATION ON THE LUNGS OF CHILDREN

本文将１８０具（男９８，女８２）小儿尸解分６个年龄组，对肺的形态、肺裂、肺门及肺下界的体表投影等作了观测，结果如下：（１）肺以左二叶右三叶者为多见（占８７．７８±２．４４％）；（２）肺的副裂和叶间裂大多不完整（分别占７４．４４±３．２５％、５５．２８±２．６２％）；（３）小儿肺下界的体表投影较成人高．

One hundred and eighty children’s cadavers(98 males,82 females)have been dividedinto six groups. The form,fissure,hilum and projection of the inferior margins of lungs have beenobserved and measured.The results show:(1)Two lobes of left lung and three lobes of right lungare in most of the cases(87.78 ± 2.44%).(2)The horizontal fissure and oblique fissure of thelungs are not complete in most children(74.44±3.25%,55.28±2.62%).(3)The projection ofthe inferior margins of thc lungs are higher in children than in adults.
