[Excretion of certain micro-molecular proteins in urine of patients with acute and chronic virus B hepatitis].

The aim of the study, was to evaluate the excretion of amylase, lysozyme and beta 2 microglobulin (B2-M) in patients with acute and chronic virus B hepatitis. The gathered findings show the maintained ability of tubules cells to reabsorption lysozyme and B2-M. The elevated excretion of amylase in the urine of patients with acute viral hepatitis show the transient decrease of abilities to absorb this enzyme by teh cells of the tubules. It may be caused by the saturation of the catabolic mechanism of the proteins in tubule cells as well as the decrease of their energetic abilities due to toxic activity of bilirubin and bile acids.
