[Xanthurenuria at different stages of liver lesion induced by protein and choline deficiency].

The parallelism between xanthurenuria and liver affections caused by protein and choline deficiency was studied. At the stages marking the development of lipohepatosis and fibrosis there occurred an intensive passage of xanthurenic acid. The intensity of xanthurenuria at the stage marking the appearance of hyperplastic nodes continued to gain strength. With progressive advance of pathological changes, which by the 9--12th months of the experiment reached the stage of a fully developed nodular cirrhosis xanthurenuria gradually stopped.
