Studies on environmental carcinogenesis in People's Republic of China.

1.胃癌(1)咸肉、咸鱼干、醋面具有较强的致突变性。(2)改善高危地区的饮食习惯与改善高危地区的胃粘膜有关，中国说。(3)弯曲杆菌感染与胃癌的相关性正在研究中。(4)慢性黏膜下炎时血管毛细血管呈退行性改变。(5)切除的胃组织可进行体外培养，标本正在研究中。(6)新的单抗GLO13对中国的诊断有一定价值。(7)绿黄蔬菜的出现频率变化与血清胡萝卜素变化呈正相关。(8)日本有4000名居民测量了血清中的β-胡萝卜素，目前正在进行跟踪调查。(9)中国用中药治疗慢性胃炎近百例。(10)一种新的亚甲基蓝方法可明确日本人胃粘膜肠化的程度和程度。水果的摄入抑制了胃肠化的进展。结果：1.肉食促进了胃壁细胞的增殖。肺癌(1)沈阳市肺癌发病年龄早于京都。鳞状细胞癌多见于39岁以下的年轻人群，中国多见于小细胞癌。中国人肺癌中以腺囊性癌多见。采用痰和胸部间接摄片进行人群筛查显示，中国抚新肺癌患病率较高。细胞球蛋白的DNA定量诊断目前正在研究中。(2)对100例肺癌患者和200例对照进行病例对照研究。

1 . Stomach cancer (1) Salted pork, dried salted small fishes and vinagered noodle showed strong mutasgenieity. (2) Improving dietary habit in a high risk area, China, is associated with improving stomach mucosa in the high risk area. (3)The correlaton between campylobacter infection stomach cancer is now under study. (4) Regressive changes of cappillary of blood vessel in chronic inflammation of submucosa were found. (5) Resected tissues of stomach could be cultured out of body the specimens are under study. (6) New monoclonal antibody GLO13 is useful for diagnosis in China. (7) Positive association of changes in frequency of Green-yellow vegetable and changes in serum carotene for one year was observed. (8) Four thousands inhabitants measured serum beta -carotene in Japan are following up. (9) About 100 cases with chronic gastritis are treated by traditional herbs medicine in China. (10)A new method of methylen blue could be clarified extent and degree of intestinalisation of gastric mucosa in Japan. Intake of fruits inhibited progression of gastric intestinalisation. Meat intake promoted proliferation of parietal cells of stomach.2 . Lung Cancer (1) Age at onset of lung cancer was younger Shenyang than in Kyoto. Squamous cell carcinoma for the younger age groups less than 39 was frequently observed in Japan and small cell carcinoma was in China. Adeno-cystic carcinoma was frequently found in Chinese lung cancer. Mass screening using sputum and chest indirect radiography showed a relatively high prevalence of lung cancer in Fusin, China. DNA quantitative diagnosis on cytologin specinems is now under study. (2) Case-control study on lung cancer was carried out the data of 100 cases and 200 controls were now under study.
