详细
论证。脂质过氧化过程是损伤生物膜的普遍机制之一。其产物丙二醛水平被视为机体适应能力的非特异性标志物。若特定金属比例与氧化–抗氧化体系平衡之间存在紧密关联,则可获得用于比较高人为负荷(工业化城市)与低人为负荷(农村地区)区域居民生活质量的生物学标志物。
目的。确定城市环境状态、脂质过氧化过程活性与青春期儿童血清金属含量之间可能存在的关系。识别此类关系对于构建适用于不同暴露强度条件下人体适应储备的统一指标体系具有必要性。
方法。对居住在城市与农村地区的48名青春期儿童血清样本进行原子吸收光谱分析,测定铁(Fe)、铜(Cu)、锌(Zn)、锶(Sr)及铅(Pb)含量。记录受试者身高、体重及体表面积。丙二醛浓度在青春期潜在健康儿童的血清中采用硫代巴比妥酸反应法进行测定。 分别按研究分组对丙二醛与金属浓度分布进行统计分析;相关性采用Spearman方法评估。为评估单项指标的显著性,使用判别分析和多元回归。
结果。Sr含量的变化与丙二醛水平及其他金属无显著相关。Cu与丙二醛以及其他金属之间存在较为明显的相关性。Cu浓度的变异趋势与Fe相似,但表达程度明显较弱。在多元回归模型中,Cu与Zn及体表面积具有最高统计显著性。判别分析表明,Pb含量由城市生态系统特征所决定,而儿童脂质过氧化过程活性可随环境城市化程度显著变化,在城市条件下呈统计学显著升高。
结论。确认了人为负荷强度、脂质过氧化过程活性及儿童血清金属含量之间的关联,这些关系可用于评估机体适应储备。此外,丙二醛与锌、铁、铜之间也存在相关性。居住在高人为负荷城市环境的儿童血清丙二醛水平更高。金属与丙二醛之间的关系可作为人体适应储备评估的参考指标。
