英国的科学家们表示，一项简单的皮肤拭子检查可用来帮助诊断退化性大脑疾病帕金森病。对志愿者的研究表明，该检查能迅速测出皮脂中显示患病迹象的化合物，皮脂是一种保护皮肤的油性物质。There are an estimated 145,000 people living with Parkinsons in the UK, but there is no cure and no definitive1 test for the disease.据估计，英国约有14.5万人患有帕金森病，但现在没治愈该病的办法，也没能测试出该病的靠谱方法。The researchers say trials on 500 people showed a skin swab could correctly identify 85% of cases.研究职员们说，对500人进行的试验表明，有一项皮肤拭子检查可以正确辨别85%的病例。Their new technique works by analysing compounds found in the sebum the oily substance that coats the skin and identifying changes in people with the disease.他们的新技术依赖剖析皮脂（包裹皮肤的油性物质）中的化合物，并辨别它们在病人身上的变化来进行测试。The team at the University of Manchester said this is the first step towards what could be a fast, painless and cheap form of diagnosis2. It could also be used to track the progression of Parkinsons and to measure whether new experimental treatments are having an impact.曼彻斯特大学的研究团队表示，这是达成迅速、无痛、便宜诊断方法的第一步。这项技术还可以用来追踪帕金森病的病情变化，并测试新的实验性治疗是不是有效。
