实验犬尘肺X线不规则形小阴影与病理对照的观察

COMPARATIVE STUDIES BETWEEN RADIOGRAPHIC SMALL IRREGULAR OPACITIES AND PATHOLOGICAL CHANGES OF EXPERIMENTAL PNEUMOCONIOSIS IN DOGS

本文对实验性尘肺不规则形小阴影为主的X线表现与病理所见进行对比观察,证实X线不规则形小阴影病理基础主要是由支气管及其分支系统及其周围组织的间质纤维化,以及支气管、细支气管周及肺实质内散在的条索状、斑片状粉尘纤维灶的重合、组合等因素综合而成。

Radiograpnic small irregular opacities ana patnological cuanges of experimental pneumoconiosis were observed comparatively. Result confirmed that the pathological basis of the x-ray small irregular opacities was the interstitial fibrosis in bronchial tree and its surrounding tissues, and the scattered cord-like macular-patchy fibrotic dust foci in peribronchial and peribronchiole tissues and in pulmonary parenchyma which resulted as the opacities in radiographs by overlapping.
