铁强化剂降低血铅的作用

Effect of Iron Fortifiers on Blood Lead Exclusion in Rats

  • 摘要: 目的 研究铁拮抗铅毒性的作用并比较几种铁强化剂的驱铅效果.方法 将56只Wistar大鼠随机分为空白对照组、模型对照组、阳性药物组、硫酸亚铁组(FeSO4)、乳酸亚铁组(C6H10FeO6)和高、低乙二胺四乙酸铁钠(NaFeEDTA)共7组,对除空白对照组外的各组大鼠进行染铅.4周后,在继续染铅的同时,除前两组外,其余5组分别给予二巯基丁二酸(DMSA)、FeSO4、C6H10FeO6和高、低浓度的NaFeEDTA溶液.8周后实验结束,进行血铅的测定.结果 高、低浓度NaFeEDTA组的血铅水平显着低于模型对照组,而且高浓度NaFeEDTA组的相对血铅下降量显着大于硫酸亚铁组和乳酸亚铁组.结论 铁具有拮抗铅毒性的作用,而且NaFeEDTA对于降低大鼠血铅的作用优于硫酸亚铁和乳酸亚铁.

     

    Abstract: Objective To explore the effect of iron against the toxicity of lead and compare the lead exclusion effects of several iron fortifiers.Methods Random design method was employed and before the study fifty-six Wistar rats were randomly divided into seven groups including blank control group,negative control group,positive control group,ferrous sulfate(FeSO4)group,ferrous lactate(C6H10 FeO6)group and two level(high,low)sodium iron ethylenediaminetetraacetate(NaFe EDTA)groups.Except the blank control group which only received double distilled water treatment throughout the experiment all the other rats were treated with lead solution.Four weeks later except for the blank and model control groups the other five groups were treated with DMSA,FeSO4,C6H10 FeO6 and two level NaFe EDTA(high,low)solutions respectively at the same time.Eight weeks later when the study was finished the blood lead level was determined.Results The blood lead levels of high and low level NaFe EDTA groups were significantly lower than that of model control group,and the relative reducing level of blood lead in high level NaFe EDTA group was higher than those of FeSO4 group and C6H10 FeO6 group significantly.Conclusion Iron can counteract the lead toxicity and the effect of NaFe EDTA reducing the blood lead was the best among the three kinds of iron fortifiers.
