Abstract
Previously I reported that the methionine contents in serum of the patients of pulmonary tuberculosis were not related to the condition of tuberculosis, but closely to the liver functions and increased when these were disturbed. In this report I discussed the correlations between the methionine contents, amino·acid nitrogen, and non-protein nitrogen in serum.
It was observed that when liver functions were slightly disturbed, the methionine content increased somewhat and a correlation between the methionine content and amno·acid nitrogen was singnificant, though a correlation between the methionine content and non-protein nitrogen was insignificant. Also it was observed that when liver functions were severely disturbed the methionine content increased extraordina-rily, and that especially at an acute, diffused, and severe liver damage, amino·acid nitrogen and non-protein nitrogen increased similarly.
