title: Analysis of the relationship between liver regeneration rate and blood levels.
abstract: OBJECTIVE
  The aim of this study was to investigate the difference of liver function changes according to the liver regeneration rate after liver transplantation through blood tests.
  
  
  METHODS
  Fifty donors, who underwent computed tomography (CT) 3D volumetry, were analyzed before and after liver transplantation. CT 3D volumetry was used as a study method to measure the mean liver regeneration volume and regeneration rate. Then, blood levels were measured including alanine transaminase (ALT), aminotransferase (AST), gamma-glutamyl transpeptidase (GGT) and total bilirubin.
  
  
  RESULTS
  The liver regeneration rate rapidly increased from 39.13±4.91% befoone1 month and 90.31±13.09% 16 months after surgery furthermore. Blood levels rapidly increased 7 days after surgery and then decreased 16 months after surgery compared to the state before surgery.
  
  
  CONCLUSIONS
  This study results could be used as a basis for the prognosis of future liver transplantations.
