Sulforaphane alleviates infiltration of inflammatory cells into the lungs of arsenic-exposed Nrf2-WT mice. Cell differential analysis was performed on the BAL cells from each mouse. Following staining, at least 200 cells were counted under the microscope. The absolute number of total cells, macrophages, neutrophils, or lymphocytes was plotted. Results are expressed as means±SD (n=5), *p<0.05 versus “Con” in Nrf2-WT group, #p<0.05 versus “Con” in Nrf2-KO group, ^p<0.05 “SF+As” versus “As” group.
