本文分析美国麻省综合医院病理科1960～1970年所见30例硬皮病尸解的肺部病变。30例的组织切片,分别作了弹力纤维染色,胶原纤维染色和酸性粘多糖染色。测量血管的直径是以口径最狭处两侧的外弹力板间距离为标准。将肺血管的大小分为大(>1000μ)、中(100～1000μ)、小(<100μ)3种类型。血管内膜和中膜的增厚程度也分为4级。肺部的纤维化程度,根据尸解时肉眼所见及组织学检定分4级。平滑肌的增生也作为纤维组织增生的一部分。
This article analyzes the pathology of Massachusetts General Hospital from 1960 to 1970 in 30 cases of scleroderma lung disease. 30 cases of tissue sections, respectively, made of elastic fiber staining, collagen staining and acid mucopolysaccharide staining. The diameter of the blood vessel is measured by the distance between the outer elastic plates on both sides of the narrowest diameter. The pulmonary vascular size is divided into large (> 1000μ), medium (100 ~ 1000μ), small (<100μ) 3 types. Intimal and tunica media thickening is also divided into four levels. Pulmonary fibrosis, according to the naked eye when the naked eye can see and histological grade 4. Smooth muscle hyperplasia also acts as a part of fibrosis.
