Bronchial mucosa and bronchial basement membranes of man and of healthy slaughter animals were examined with the scanning electron microscope. The surface relief of the normal human bronchus mucosa is composed of a system of bulge-like prominences and valleys. There are parallel recesses and narrow valleys which run parallel to the longitudinal axis of the bronchus. Man and pig have the same kind of surface relief in bronchus. A fundamental different type of surface area relief is exhibited by the cow and the sheep. The bronchial basement membrane is a homogeneous plate with dune-like prominences and trough-shaped depressions. Often one can see perforations of variable size. The structures of the basement membranes have a great variability and no species-specifity. There are the same types of dysplasias in the bronchus mucosa in man and in animals. The differences are based upon in the wideness of the expansion and in the grade of the dysplasias in man.
用人和健康屠宰动物的支气管黏膜及支气管基底膜进行扫描电子显微镜检查。正常人支气管黏膜的表面形态由隆起样突出和凹陷组成。有与支气管纵轴平行的平行凹槽和狭窄沟谷。人和猪的支气管有相同类型的表面形态。牛和羊则表现出一种根本不同类型的表面积形态。支气管基底膜是一块有沙丘样突出和槽形凹陷的均质板。常可见到大小不一的穿孔。基底膜的结构有很大变异性，无物种特异性。人和动物支气管黏膜存在相同类型的发育异常。差异在于人类发育异常扩展的宽度和程度。
