法国里昂国际抗癌研究机构的环境致癌物和宿主因子部门的领导人Helmut Bartsch在由美国肿瘤学会主持的科学作家讨论年会上称,有一种新的、无创伤性的简单试验可检出亚硝胺形成率高的一些人,这些人可能有患胃癌,食管癌和膀胱癌的高度危险性。这种鉴别方法又可引伸为预防的方法。继此之后,他们和许多国家的临床医师进行了合作,将上述方法用于病人。绝大多数病人患有胃病,如萎缩性胃炎、恶性贫血或胃切除后的病人。上述新试验法没有发生任何问题。病人喜欢饮用研究人员给与的一种可口汁。此汁含有硝酸盐。以后给与的是脯氨酸溶液,这是一种 Helmut Bartsch, director of the Environmental Carcinogen and Host Factors Division at the International Agency for Research-Based Oncology in Lyon, France, said at a meeting of scientific writers chaired by the American Oncology Society that a new, noninvasive and simple trial could detect sub-Asian Some people with high rates of nitramine formation may have a high risk of gastric, esophageal, and bladder cancer. This method of identification in turn can be extended as a preventive approach. Since then, they have worked with clinicians in many countries to apply the above approach to patients. Most patients suffer from stomach problems, such as atrophic gastritis, pernicious anemia or gastrectomy patients. The new test method without any problems. The patient likes to drink a researcher to give a delicious juice. This juice contains nitrate. After the proline solution is given, this is a
