[Correlation between changes in lungs and the composition of amino acids in blood plasma caused by industrial dust. II. Studies on workers occupationally exposed to industrial dust].
Results of determination of free aminoacids in blood plasma of workers exposed to ceramic and grinding dusts as well as welding fumes are presented. In the blood plasma of those employed in ceramic factory or welders a significant decrease of free aminoacids in comparison with the control group was found except for hydroxyproline, whose content increased during the 25 year-employment. In experiments on animals a significant increase of total aminoacids content in lungs with simultaneous decrease of free aminoacids amount in blood plasma was observed. Similar changes in workers' blood plasma make us conclude that aminoacids content in human lungs may also increase, which is indicative of fibrinogenic processes.
