BACKGROUND/AIMS: The aim of this study was to investigate the precise mechanism of liver failure by hydralazine derivatives, with special reference to liver regeneration failure.METHODS: Histone acetylation and proliferation of hepatocytes were evaluated by immunohistochemistry with anti-acetylated

We assessed four antimutagenic compounds' influences on DNA repair in human lymphocytes exposed in vitro to hydrogen peroxide (20 microM, 5 min, at 4 degrees C). DNA damage and repair were estimated by means of alkaline single cell gel electrophoresis (comet assay). It was noticed that the enhanceme
