共尸检50例,其中50岁以上15例,其他35例。计慢性气管炎7例,支气管扩张3例,肺炎23例,对照组17例。按全国标准,自右肺取材,每例取12块。慢性气管炎的病理特征为粘膜上皮杯状细胞数值较高,气管中各部位的分布较均匀。上皮增生、化生变性等现象均较明显。固有膜和粘膜下层一般均有淋巴细胞,浆细胞和中性白细胞浸润,并较严重。腺体和粘膜下层厚度比值较高,全部病例均有腺导管扩张。肺气肿较普遍,并较严重(支气管扩张为最)。气管炎、支气管扩张10例中3例有肺心病。慢性气管炎中突出病变是粘膜上皮杯状细胞增
A total of 50 cases of autopsy, of which more than 50 years old in 15 cases, the other 35 cases. 7 cases of chronic bronchitis, bronchiectasis in 3 cases, 23 cases of pneumonia, control group of 17 cases. According to the national standard, drawn from the right lung, each case take 12 pieces. Chronic bronchitis pathological features of mucus epithelial goblet cells higher values, the trachea in the distribution of more uniform parts. Epithelial hyperplasia, metaplasia and other phenomena are more obvious. Inherent membrane and submucosa generally have lymphocytes, plasma cells and neutrophils infiltration, and more serious. The ratio of glandular to submucosal thickness was high, and all cases had glandular duct dilatation. Emphysema is more common and more severe (bronchiectasis most). Bronchitis, bronchiectasis in 10 cases, 3 cases of pulmonary heart disease. Outstanding lesions in chronic bronchitis mucosal epithelial goblet cells increased
