||Three cases of idiopathic interstitial pneumonia with bullae seen in schoolteachers
||Sep. 1995, Vol.28, No.3, p.425-435. Illus. 19 ref.
||Three cases are presented of Japanese school teachers with chronic interstitial pneumonia and multiple bullae throughout the lungs. Analysis of lung mineral contents revealed that the deposition of total dust, inorganic dust, non-silica inorganic dust and calcium was higher than that in four control cases with the same disease; the amount of free silica in one case and alpha-quartz in another were also higher than in the controls. Much of the chalk produced in Japan is still made from gypsum with small amounts of silica and other minerals, in addition to calcium. Findings indicate the deposition of chalk in the lungs of these patients.
