Abstract Background Borax is used as a food additive. It becomes toxic when accumulated in the body. It causes vomiting fatigue and renal failure. Methods The heparinized blood samples from 40 healthy men were studied for the impact of borax toxicity on immune cell proliferation lymphocyte proliferation and sister chromatid exchange in human chromosomes. The MTT assay and Sister Chromatid Exchange SCE technic were used in this experiment with the borax concentrations of and mg ml. Results It showed that the immune cell proliferation lymphocyte proliferation was decreased when the concentrations of borax increased. The borax concentration of mg ml had the most effectiveness to the lymphocyte proliferation and had the highest cytotoxicity index CI . The borax concentrations of and mg ml significantly induced sister chromatid exchange in human chromosomes P . Conclusion Borax had effects on immune cell proliferation lymphocyte proliferation and induced sister chromatid exchange in human chromosomes. Toxicity of borax may lead to cellular .
