本文报告镉、砷的亚慢性联合作用对大鼠免疫功能影响的研究。大鼠分别或联合经饮水给以镉和砷,高、低剂量分别为经口LD50的1/20和1/100,观察12周。结果发现:第6周时,低镉组的ANAE(78.6±9.66)和低砷组的ANAE(73.6±4.21)比对照组(72±15.6)略高(P>0.05),高镉组
This article reports the effects of subchronic combined effects of cadmium and arsenic on immune function in rats. Rats were administered cadmium and arsenic separately or in combination with drinking water. The high and low doses were respectively 1/20 and 1/100 of the oral LD50 and were observed for 12 weeks. The results showed that ANAE in low cadmium group (78.6 ± 9.66) and ANAE in low arsenic group (73.6 ± 4.21) were slightly higher than those in control group (72 ± 15.6) (P> 0.05)
