吸入金属铝粉能否引起尘肺,国外报导意见不一致。国内尚未见有报导。我们对接触铝粉尘工人进行临床观察外,并对铝粉的致病性进行了实验研究。材料和方法实验用金属铝粉为融喷法生产之粒状粉末。经二甲苯稀释,取稀释度适当的涂片测其分散度。粒子直径1～4微米占75%;5～10微米占22%;11～15微米占3%。上述铝粉制成1毫升含50毫克之蒸馏水混悬液,高压灭菌后加入2000单位青霉素钾盐与0.05克硫酸链霉素。对照组动物不加铝粉,其他条件相同。
Inhalation of aluminum powder can cause pneumoconiosis, inconsistent reports of foreign reports. There have been no reports in China. We conducted a clinical observation of workers exposed to aluminum dust and conducted experimental studies on the pathogenicity of aluminum powder. Materials and methods Experimental aluminum powder for the melt-jet method of production of granular powder. After xylene dilution, take the appropriate dilution smear measured its dispersion. Particle diameter of 1 to 4 microns accounted for 75%; 5 to 10 microns accounted for 22%; 11 to 15 microns accounted for 3%. The above aluminum powder was made into 1 ml suspension containing 50 mg of distilled water, and after autoclaving 2000 units of penicillin potassium salt and 0.05 g of streptomycin sulfate were added. Control animals without aluminum powder, the other conditions are the same.
