Abstract
In 50 surgical cases with liver and biliary tract diseases, liver proteins were analyzed by the method of Sato et al., giving the results as follows:
1. The abnormal patterns of liver proteins in liver and biliary tract diseases were much more frequent as compared with those in stomach diseases.
2. In liver and biliary tract diseases, the abnormality in the protein composition was common even in cases without any clinical evidence of functional disturbances of the liver as well as in those with the perceptible disturbances.
