Abstract
This study was designed to investigated the effects of cadmium(Cd) feeding on the humoral immune responses such as PFC-responses and production of immunoglobulins in BALB/c mice. The results obtained were summarized as follows; 1. Total PFCs of direct IgM antibody response were significantly decreased in all Cd-fed goups, whereas total PFCs of IgG antibody response were slightly increased. 2. In secondary immunization, total HA titers were increased in all Cd groups as compared with control, especially in 100ppmm group and also IgG titers were slightly increased except for 50ppm group. 3. The levels of $IgG_1$ were increased to 5.5% 18.7%, 17.4% and 7.2% in 25, 50, 100 and 200ppm groups as compared with control, respectively. And also the levels of IgE were increased to 5.7%, 7.3%, 8.7% and 0.4% in those of Cd groups, in order. Conclusively, concentrations of $IgG_1$, and IgE were increased in all Cd groups. Based on the results of this study and previous report, it was shown that Cd might affect humoral immune responses by modifying the distribution and function of cells playing in the cellular immune response.
Key Words: cadmium, humoral immune respones, BALB/c mouse
