Cd是主要的工业污染金属之一,较广泛地存在于工业环境和受污染的生活环境中。其对人及动物的某个器官或某个系统的毒性,国内外已进行了大量的研究。近年来又开展了Cd对免疫系统影响的研究。国内外的一些研究表明,Cd可抑制体内外的抗体生成反应和体外淋巴细胞增殖反应。但未见整体动物接触Cd对体内淋巴细胞转化影响的报道。 Cd is one of the major industrial pollution metals, widely found in industrial environments and contaminated living environments. Its toxicity to an organ or a certain system of humans and animals has been studied extensively at home and abroad. In recent years, another study of the impact of Cd on the immune system. Some studies at home and abroad show that Cd can inhibit the antibody production reaction in vivo and in vitro and the lymphocyte proliferation reaction in vitro. However, no overall animal exposure to Cd on the impact of lymphocyte transformation reported.
