    摘要:

    目的 评价排铅食品对铅中毒小鼠的排铅功效。方法 选用90只18~22g昆明种雄性小鼠,随机分为6组:阴性对照组、醋酸铅模型组、阳性药物组、低剂量组、中剂量组和高剂量组。除阴性对照组自由饮用去离子水外,其他各组均自由饮用1.00 g/L醋酸铅水溶液染毒。30 d后,剂量组按人体推荐摄入量0.60 g/(kg BW?d)的5、10和20倍经口灌胃,阳性药物组灌胃二巯基丁二酸(dimercaptosuccinic acid)溶液,模型对照组和阴性对照组灌胃去离子水。1个月后测定全血、肝、股骨、肾和脑中铅含量。结果 3个剂量组血、肝、肾和脑铅含量比醋酸铅模型组明显降低(P<0.05或P<0.01),高、中剂量组股骨铅含量比醋酸铅模型组明显降低(P<0.01);结论 排铅食品具有明显促进小鼠体内铅排出作用。

    Abstract:

    Objective To evaluate the lead-eliminating effectiveness of a lead-excreting food on lead poisoning in mice. Methods Ninety Kunming male mice with body weight of 18?22g were randomly divided into six groups: negative control group, lead poisoning model group, positive control (lead-eliminating medicine) group, and low, medium and high dose lead-excreting food treated groups. Except the negative control group freely drinking deionized water, other groups were drinking water contained 1.00g / L of lead acetate freely for 30 days for lead exposure. The mice in treated groups were given the lead-excreting food by gavage, based on 5-, 10- and 20-fold of the recommended dosage for human consumption (0.60 g / (kgBW?d)). The mice in the positive control group were given dimercaptosuccinic acid (DMSA) solution, and the mice in model control group and negative control group were given deionized water by gavage. The lead content of whole blood, liver, femur, kidney and brain was determined a month later. Results The lead content in blood, liver, kidney and brain of the three lead-excreting food treated groups was significantly lower than that of the lead poisoning model group (P <0.05 or P <0.01); the lead content in the femur of high and medium dose lead-excreting food groups was significantly lower than the lead poisoning model group (P <0.01); Conclusion The lead-excreting food is effective in eliminating lead from mice.
