Mercury is a ubiquitous environmental toxicant that causes a wide range of adverse health effects in humans. Three forms of mercury exist: elemental, inorganic and organic. Each of them has its own profile of toxicity. The aim of the present study was to determine the effect of thimerosal, a topical antiseptic and preservative in vaccines routinely given to children, methyl mercury, and mercuric chloride on cellular viability measured by MTT in Jurkat T cells, a human T leukemia cell line. The treatment of Jurkat T cells with thimerosal caused a significant decrease in cellular viability at 1 μM (25%, p<0.05; IC50: 10 μM). Methyl mercury exhibited a significant decrease in cellular viability at 50 μM (33%, p<0.01; IC50: 65 μM). Mercuric chloride (HgCl2) did not show any significant change in cellular survival. Our findings showed that contrary to thimerosal and methyl mercury, mercuric chloride did not modify Jurkat T cell viability.
汞是一种普遍存在的环境毒物,会对人类健康造成广泛的不良影响。汞有三种形式:元素汞、无机汞和有机汞。它们各自具有不同的毒性特征。本研究的目的是确定硫柳汞(一种常用于儿童常规接种疫苗的局部防腐剂)、甲基汞和氯化汞对人T白血病细胞系Jurkat T细胞中通过MTT法测定的细胞活力的影响。用硫柳汞处理Jurkat T细胞后,在1μM时细胞活力显著下降(25%,p<0.05;IC50:10μM)。甲基汞在50μM时细胞活力显著下降(33%,p<0.01;IC50:65μM)。氯化汞(HgCl2)在细胞存活率方面未显示任何显著变化。我们的研究结果表明,与硫柳汞和甲基汞不同,氯化汞不会改变Jurkat T细胞的活力。
