One or more bronchi are visualized end-on roentgenographically in the parahilar zone of the PA chest and they range in diameter from 3 to 7 mm. Thickening of bronchial walls visualized end-on is an occasional roentgenographic manifestation of certain disease notably chronic bronchitis, diffuse interstitial lymphoma and interstitial pulmonary edema. We reviewed PA chest films of some 727 normal subjects and 371 cases of silicosis seen at the Department of Radiology, St. Mary's Hospital, Catholic Medical College during the year 1979. Of these, we sampled 30 cases each for matched age groups , both normal and silicosis subjects, in which bronchial wall were clearly visualized at parahilar zones. Thus, a total of 180 cases were assessed of the thickness of bronchial wall and the ratio of wall thickness to outer diameter of bronchi. The following results were obtained. 1. The mean of the outer diameter of the bronchi of the normal subjects was 5.32$\pm$1.21mm, and 5.31$\pm$0.92 mm in s licosis. No significant differences were noted between two groups each age groups. The bronchi measuring 2.5-5.0 mm in size were most prevalent in both normal and silicotic subjects. 2. A sto bronchiai wall thickness, the mean of the normal and silicisis subjects were 0.81$\pm$0.34m , and 1.19$\pm$0.41mm, respectively. The bronchial wall measuring 0.5mm in thickness was most prevalent in the normal subjectsand 1 mm in silicosis. The difference was significant(p<0.001). 3. In ratio of wall thickness to outer diameter was 0.15$\pm$0.06 in the normal subjects and 0.22$\pm$0.07 in silicosis, respectively. The difference was significant(p<0.001).
