【摘要】 亚硝胺类化合物致癌问题已受到普遍重视。本文表明:浅表性胃炎患者胃液亚硝酸盐含量为0.0110±0.0057mg-N/dl。胃癌患者胃液亚硝酸盐含量为0.0298±0.0243mg-N/dl,显著高于浅表性胃炎患者(P<0.002)。萎缩性胃炎患者胃液亚硝酸盐含量为0.0218±0.0220mg-N/dl,亦明显高于浅表性胃炎患者(P<0.05)。提示胃癌发病与胃液内亚硝酸盐含量增高密切相关。更多还原

【Abstract】 Attention is now universally paid to the problem of the carcinogenicity of n-nitroso compound. This article indicates that the content of nitrite in the gastricjuice of the patients with superficial gastritis is 0.0110±0.0057 mg--N/dl; that thecontent of nitrite in the gastric juice of the patients with gastric cancer is 0.0298±0.0243 mg--N/dl and is significantly higher than that of the patients with super-ficial gastritis (p<0.002). The content of nitrite in the gastric juice of the patientswith chronic atrophic gastritis is 0.0218±0.0220 mg--N/dl and is significantlyhigher than that of the patients with superficial gastritis (p<0.05). It is pointedout that there is a close relationship between gastric cancer and the increase ofthe content of nitrite in gastric juice.更多还原
