日本京都大学医学部副主任、微生物教研室主任伊藤洋平教授于1980年8月29～30日访问广州,并作了学术报告。其中提出鼻咽癌(NPC)病因学的新观点,认为口腔细菌产生的丁酸等及可能食入的某些植物成分,或能起到激活EB病毒的作用,从而引起肿瘤。此说提法新颖,但作结论尚为时太早,它能提供一种工作假说,以待进一步研究。现特将其假说摘译出以供参考。 Professor Ito Yohei, deputy director of the Department of Medicine and Director of the Division of Microbiology, Kyoto University in Japan, visited Guangzhou from August 29-30, 1980, and gave a lecture. Among them, a new view of the etiology of nasopharyngeal carcinoma (NPC) is proposed. It is believed that butyric acid produced by oral bacteria and certain plant components that may be ingested may act to activate Epstein-Barr virus and cause tumors. This formulation is novel, but it is too early to draw conclusions. It can provide a working hypothesis for further study. The hypothesis is specifically extracted for reference.
