Genome damage in peripheral blood lymphocytes of diabetic and non-diabetic individuals after intervention with vegetables and plant oil.

abstract：:Photomutagenicity assays are required for regulatory submissions of some chemicals. As yet there are no well-validated protocols available for these assays. Critical factors which may contribute to the ability of a bacterial assay to detect photomutagens (e.g. dose of UV and test chemical, exposure conditions, light s...
