代谢
钒主要通过吸入吸收,尽管少量可以通过皮肤和消化道吸收。它在血浆中迅速分布,主要分布到肾脏、肝脏、肺、心脏、骨骼,在这些地方它倾向于积累。在细胞色素P-450酶的帮助下,它可以在其两个氧化状态之间相互转化,即钒(IV)(V+4)和钒酸盐(V+5)。钒的这两种状态都可以可逆地与血液中的转铁蛋白结合,然后被红细胞摄取。钒主要通过尿液排出。(L837)
Vanadium is absorbed mainly via inhalation, though small amounts can be absorbed through the skin and gastrointestional tract. It is rapidly distributed in the plasma, mainly to the kidney, liver, lungs, heart, bone, where it tends to accumulate. With the help of cytochrome P-450 enzymes, it can interconvert between its two oxidation states, vanadyl (V+4) and vanadate (V+5). Both states of vanadium can reversibly bind to transferrin protein in the blood and then be taken up into erythrocytes. Vanadium is excreted mainly in the urine. (L837)

毒理性
  • 毒性总结
钒通过降低巨噬细胞膜的完整性来损害肺泡巨噬细胞,从而影响细胞的吞噬能力和生存能力。钒的五价形式,钒酸盐,是细胞膜上Ca2+-ATP酶和Na+,K+-ATP酶的强效抑制剂,这会降低细胞内ATP的浓度。还认为钒能诱导活性氧种类的产生。这可能损害DNA并导致氧化应激,从而损害生殖系统。钒还能抑制蛋白质酪氨酸磷酸酶,产生类似胰岛素的效果。
Vanadium damages alveolar macrophages by decreasing the macrophage membrane integrity, thus impairing the cells' phagocytotic ability and viability. The pentavalent form of vanadium, vanadate, is a potent inhibitor of the Ca+-ATPase and Na+,K+-ATPase of plasma membranes, which decreases intracellular ATP concentration. Vanadium is also believed to induce the production of reactive oxygen species. This may damage DNA and also cause oxidative stress, which can damage the reproductive system. Vanadium also inhibits protein tyrosine phosphatases, producing insulin-like effects. (L837, A247, A248, A249, A250, A251)
