Determination of the amino acid contents of coalworkers' lungs after correction for blood, fat, dust and collagen

Abstract

The amino acid contents of dust-affected coalworkers' lungs, complicated pneumoconiotic lesions, the remainder of the lungs from which the lesions had been removed and dust-free control lungs have been determined. The results have been corrected for blood, dust, fat and collagen content, but no significant differences between dust-free and dust-affected lungs were found. The residual amino acid results, after correction, closely resembled the results for glycoprotein extracted from human lung pleura and aorta.
