Abstract

Male, weanling Sprague-Dawley rats were fed a diet containing 206 μg tin (as stannous chloride)/g feed for 21 days. The rats fed the test diet lost significantly more zinc in their faeces and retained significantly lower levels of zinc in their tibias and kidneys than rats fed the control diet (which contained 1 μg tin/g). The rats fed the tin-supplemented diet retained significantly higher levels of tin in their kidneys and tibias and significantly lower levels of copper in their kidneys than the control animals.

日粮锡对大鼠锌、铜、铁利用的影响
用含206 μg锡(以氯化亚锡的形式)/g饲料喂养断奶雄性sd大鼠21 d。与对照组(含1 μg锡/g)相比,喂食试验饲料的大鼠粪便中的锌含量明显减少,胫骨和肾脏中的锌含量明显降低。与对照组相比,喂食补锡饮食的大鼠肾脏和胫骨中的锡含量明显较高,肾脏中的铜含量明显较低。
