ANTIOXIDENTS REDUCE SECONDHAND SMOKE DAMAGE
Previous studies conducted by investigators in the universitiy's Center for Environmental Sciences and Engineering have shown that exposure to workplace {ETS} results in increased oxidative stress and damage.8-Hhdroxy-2-deoxyguanonsinc,a marker of oxidative DNA damage was 63% greater in the exposed group compared with controls. Subjects in a previous study who reported workplace exposure to ETS were given a 60 day supply of an over-the-counter antioxident formulation consisting of 3,000 micrograms of beta-carotene, 60 milligrams of vitamin C,30I.U. of alpha tocopherol, 40 mg. of zinc, 40mcg of selenium and 2 mg. of copper. After the supplimentation period results were compared with presupplimentation values. A 62% decrease in 8-hyfrogy-2-deoxguannosive was observed after supplementation.
