筑波大学化学系的中井讲师等成功地发明了一种能够将癌组织中的金属浓度分布图像化的技术。中井将同癌组织增生而摘除的肾脏切片予以强力X 线照射,而后测定锌和铜的浓度分布。结果经检查的十二 Professor Nakai, who is from the Department of Chemistry at Tsukuba University, successfully invented a technology that can visualize the distribution of metal concentrations in cancerous tissues. Naijing will perform a strong X-ray exposure of the kidney slices that have been taken away from the hyperplasia of cancerous tissue, and then determine the concentration distribution of zinc and copper. The result was checked twelve
