摘要
目的观察亚慢性镉中毒性肝肾损害,并初步探讨金属硫蛋白(MT)与肝肾损害的关系。方法用Wistar大鼠腹腔注射0.5mg/kgCd2+的CdCl23次/周,共10周,染毒后不同时期处死大鼠,观察肝肾功能变化。结果染毒6周后,大鼠出现了明显的肝肾损害,相应组织中Cd∶MT的摩尔数之比均超过7,且随染毒总剂量的增加,Cd∶MT值明显增加,病变程度加重。结论肝肾是亚慢性镉中毒的靶器官,非MT结合的镉可能是损害肝、肾的主要成分。
Objective To observe subchronic
cadmium-induced liver and kidney injury,and to study the relationship between
Metallothionein(MT)and cadmium toxicity. Methods 0.5mg/kg Cd2+ as CdCl2 solution was
injected intraperitoneally,3 times/week,and the functions of liver and kidney were detected
dynamically in 10 weeks of cadmium exposure. Results After 6-week cadmium exposure,the
injury of liver and kidney was observed functionally and morphologically,and the mole ratio of
Cd over MT in corresponding tissue was greater than 7. The severity of cadmium-induced
damage increased with the increase of CdMT ratio. Conclusion Both liver and kidney are
targets of subchronic cadmium exposure,and non-MT-bound cadmium may be an important
component in cadmium pathogenesis.
