本文作者为了解铅接触者营养摄取量与血液中铅含量的关系,对日本某制钢厂所从事铅溶解、造型作业20～55岁的74名健康男性工人进行了调查研究。同时选用Wistar雄性大鼠(4周龄)做了实验。通过调查和实验研究发现: 1.膳食中无机盐(主要是钙)的含量及纤维素、铁摄取量少者,血液中铅含量很高。 2.反映体内贮存铁量的血清铁蛋白量多者,血液中铅含量少。 3.维生素摄取量多者,其血液中铅含量少。特别是维生素B_1摄取量与血液中铅含量
In order to understand the relationship between nutrient intake of lead exposure and lead in blood, the author conducted a survey on 74 healthy male workers aged 20-55 years who were engaged in lead dissolving and modeling work in a Japanese steel mill. Wistar male rats (4 weeks old) were also selected for experiments. Through the investigation and experimental research found that: 1. Dietary inorganic salts (mainly calcium) and cellulose, iron intake less, the blood lead content is high. 2. Reflect the amount of iron stored in the body of ferritin, the amount of less blood lead content. 3. More vitamin intake, the blood lead content less. Especially vitamin B_1 intake and blood lead content
