日本科学家发现,人体皮肤表层排出的气体中含有氢气和丙酮,检测这类气体可以用来诊断疾病。氢气是大肠内残留的碳水化合物及食物纤维等发酵的结果;丙酮则是在血液中缺乏葡萄糖的情况下,由脂肪酸的新陈代谢产生。一般医学常识把氢气视为人体消化不良的征兆,把丙酮作为诊断糖尿病和肥胖症等疾病的指标。科学家认为,检验这两种气体不需要抽血,可望成为诊
Japanese scientists found that the surface of human skin excretion of gas containing hydrogen and acetone, the detection of such gases can be used to diagnose the disease. Hydrogen is the result of fermentation of residual carbohydrates and dietary fibers in the large intestine. Acetone is produced by the metabolism of fatty acids in the absence of glucose in the blood. General Medical Knowledge Hydrogen is seen as a sign of indigestion and acetone is used as an indicator of diseases such as diabetes and obesity. Scientists believe that testing these two gases does not require blood, is expected to become a clinic
