稀土高背景区稀土生物学效应研究Ⅰ轻稀土区人群血液生化指标

Bio-Effect of Rare Earths in RE-High Background Region I.Some Blood Biochemical Indices from Population Resided in Light REE District

赣南轻稀土高背景区和对照区人群血液生化指标检测结果显示 ,两区人群血液诸多生化指标的总体均数有显著性差异。与对照区相比 ,轻稀土区人群具有血清总蛋白 (TSP)、白蛋白 (AL)、β 球蛋白 (β G)、谷丙转氨酶 (GPT)、血清甘油三酯 (STG)、免疫球蛋白A(IgA)等含量的总体均数降低以及胆固醇 (CHO)含量总体均数升高的趋势 ,而生化指标的显著性水平受稀土背景区生物链中稀土含量和稀土组成以及人群性别制约。轻稀土背景区不同年龄段的人群血液中的某些生化指标总体均数 ,如TSP含量显示出男性群体受稀土影响可能是一个单向不可逆的过程 ,而女性群体则反映出受稀土影响后能产生自我修复的本能。

The results of biochemical indices in human blood show that there are significant difference in the population mean of these indices between the LREE high region in South Jiangxi, China and the control. In comparison with the normal region, the contents of total serum protein(TSP), albumin(AL), β globulin (β G), glutamic pyruvic transitanase (GPT), serium triglycerides (STG) and immunoglobulin(IgA) are manifested as low, but high cholesterol (CHO) in the LREE high region. These deviations may be related to the REE concentration and composition in food chains, and also are sex dependent. Certain blood indices (such as TSP) of different age groups in the LREE high region indicate that the influence of REE on males is a one way irreversible process while females show a strong ability of restoration.
