To evaluate the potential immunotoxicity of di (2-ethylhexyl) phthalate (DEHP), RAW264.7 cells and peritoneal macrophages were treated with different concentrations of DEHP. Further, the phagoeytosis efficiency and eytokine secretion and reactive oxygen species ( ROS ) production ability of RAW264.7 cells, and adherence ability and phagoeytosis efficiency of peritoneal maerophages were determined. The results revealed that the phagocytosis efficiency of RAW264.7 cells treated with 1, 5 mg·L^-1 and 10 mg·L^-1 DEHP was significantly inhib...
