观察硝酸稀土在仔鼠体内的含量及对仔鼠免疫功能的影响。孕 7～ 8天的孕鼠经口给予 2mg/kg、2 0mg/kg、2 0 0mg/kg的硝酸稀土至仔鼠离乳 ,对刚生下的仔鼠进行稀土元素的测定。结果显示仔鼠体内稀土元素的含量随着剂量的增加而升高。稀土对刚离乳的仔鼠免疫器官重量和体液免疫功能及细胞免疫功能均有不同程度的影响
To observe the content of rare earth nitrate in offspring rats and immune function. Pregnant 7-8 days pregnant rats were orally administered 2mg / kg, 20mg / kg, 200mg / kg of rare earth nitrate to offspring of pups, just born offspring Rare earth element determination. The results showed that the amount of rare earth elements in the offspring rats increased with increasing dose.
