Bisphenol A-induced overall immune downregulation in mice

This study was undertaken to assess overall effects of bisphenol A, a monomer widely used in manufacturing polycarbonate plastics or epoxy resin, exposure on immune system of mice. For in vitro evaluation, serial concentration of SPA was added into culture of various immune cells from normal female ICR mice, and for in vivo or ex vivo assessment, mice were orally exposed to BPA dissolved in olive oil as doses of 500, 1000, 2000 mg/g b.w. for acute expose or 100, 500, 1000 mg/kg/day b.w. 5days a week for subacute exposure.
