Uptake and distribution of N-acetylcysteine in mice: tissue-specific effects on glutathione concentrations.

abstract：:Previous studies have shown that platinum-DNA adduct level in leukocyte DNA (measured by antibody methodology) is directly related to disease response in ovarian cancer and testicular cancer. To determine if this principle could be more broadly applied, platinum-DNA damage was studied in a blinded fashion in leukocyte...
