| Research Abstract |
Carbamate pesticides are widely used throughout the world in agriculture as fungicides and insecticides. Since carbamate pesticides contribute to chemical sensitivity and allergy related diseases; therefore, it is very important to investigate the immunotoxicity of carbamate pesticides and its mechanism in the perspecive of preventive medicine. In this study, we found that ziram, a carbamate fungicide, significantly inhibits natural killer (NK), lymphokine-activated killer (LAK) and cytotoxic T lymphocyte (CTL) activities. We have also found that ziram significantly induced apoptosis and necrosis in NK and T cells, and reduced the intracellular levels of anticancer proteins in NK cells, which contributed to the inhibitions of NK, LAK and CTL activities.
