镉是一种分布广泛的有毒微量金属,可能致人高血压和引起实验大鼠心血管毒性。苏联报告了接触氧化镉的工人,其心血管疾病的发病率比非接触镉工人高四倍。急性毒性实验已显示Cd与Se同时投予时Se是Cd的最有效的拮抗剂。为了探讨Cd的心血管毒性和大鼠慢性或 Cadmium is a widely distributed and toxic trace metal that may cause high blood pressure and cause cardiovascular toxicity in experimental rats. The Soviet Union reported that workers exposed to cadmium oxide had a four-fold higher incidence of cardiovascular disease than non-contact cadmium workers. Acute toxicity experiments have shown that Se is the most potent antagonist of Cd when co-administered with Se. To investigate the cardiovascular toxicity of Cd and chronic or chronic rat
