The effects of Cadmium (Cd) exposure and the treatment with Zinc (Zn) on immune functions of splenocytes and cultured lymphocytes of rats were studied. The exposure of rats to Cd was at a dose of 2.2 mg/kg CdCl2, injected subcutaneously four times weekly for 2 months. Rats were supplemented with Zn (2.2 mg/kg ZnCl2, injected subcutaneously four times weekly for 2 months) one hour prior to Cd exposure. Spleens were removed and splenocytes were isolated and cultured. The proliferation capacity of lymphocytes and their homing to the spleen were studied.
