摘要
The amino acid histidine was found to increase the toxicity of H2O2 in cultured mammalian cells. Histidine also augmented the level of DNA single strand breaks (SSB) detectable in cells exposed to the oxidant and, in addition, resulted in the appearance of DNA double strand breaks (DSB), a lesion which is not produced by H2O2 alone.
