自1973年明确了Se的生理作用之后,有些研究者发现全血或红细胞(RBC)的GSH-px活性与全血或血浆中Se浓度有明显的相关。 Se在煤和飞灰中含量较高,在煤燃烧时排入大气之中。该元素也用于橡胶生产。因此工业区与非工业区的人就可能有不同的Se状态。作者的研究目的就是要测定某电站和橡胶厂工人的全血和血浆Se浓度并与其RBC和血浆GSH-px活力相比较;也测定了他们血浆的脂质过氧化物含量,并与非工业区人员相比较。
After the physiological role of Se was clarified in 1973, some researchers found that GSH-px activity of whole blood or red blood cells (RBCs) was significantly correlated with Se concentration in whole blood or plasma. Se is high in coal and fly ash and is emitted into the atmosphere as the coal burns. This element is also used in rubber production. Therefore, people in industrial and non-industrial areas may have different Se states. The aim of the study was to determine the concentration of whole blood and plasma Se in a station and rubber factory worker in comparison with their RBC and plasma GSH-px activities; their plasma lipid peroxides content was also measured and compared with non-industrial zones Staff compared.
