摘要
为检验N-亚硝基化合物与胃癌及癌前病变的关系,本研究以山东牟平县高陵镇经胃镜筛检查出的胃癌及慢性胃炎患者为研究对象,对其空腹胃液PH值、亚硝酸盐浓度及24小时尿液N-亚硝基脯氨酸(NPRO)排出量进行了测定。结果显示,胃液PH值及亚硝酸盐浓度与胃粘膜病变程度呈正相关关系,而未见尿液N-亚硝基脯氨酸的排出量与胃粘膜病变有显著关联。
For the purpose of finding the relationships between introgastric nitrosation and precancerouslesions and gastric cancer, 87 subjects, devided into three groups Ⅰ-Ⅲ, were selected in Gao-ling,Muping County, Shandong Province in 1988 in high risk area. pH value, nitrite concentration offasting gastric juice and urinary NPRO excretion were measured. A relationship was found betweenadvanced gastric lesions and pH value of gastric juice (r=0.32, P<0.01). Nitrite concentration alsoincreased in cases with more advanced gastric lesions (r=0.24, P<0.05). No high level of NPRO hasbeen detected in subjects with more advanced lesions.
