| Research Abstract |
Albumin exists in both oxidized and reduced forms. Since oxidized albumin shows lower anti-oxidative effects, an increase in oxidized albumin seems to be associated with hepatocarcinogenesis. The aims of this study are 1) to investigate changes in redox state of albumin in patients with chronic liver disease and 2) to develop a reducing method for oxidized albumin. 1) The oxidized albumin rate was significantly increased by the severity(n=79, chronic hepatitis 28.3±1.1%, Child-Pugh A 33.5±1.2%, Child-Pugh B and C 37.8±1.3%). Furthermore, the oxidized albumin rate was significantly correlated with MELD score(R^2=0.336, P<0.001). 2) By treatment with a glycyrrhizin agent, reduced albumin rate was significantly increased(27.7±0.18% vs. 78.7±0.36%; P<0.01). The percentage of reduced albumin reached its peak at 15 min after treatment with a glycyrrhizin agent. This study showed that the oxidized albumin rate was significantly increased by disease progression. In addition, we have developed a reducing method for oxidized albumin by using a glycyrrhizin agent.
