Gender difference in DNA adduct levels among nonsmoking lung cancer patients.

abstract：:The modulation of 1,3-butadiene (BD)-induced DNA adducts by occupational exposure, glutathione S-transferase (GST) genotypes, single-strand breaks, and cytogenetic end points was studied in 15 workers and 11 controls. The exposed group consisted of 8 smokers and 7 nonsmokers, whereas the control group consisted of 7 n...
