采用MB染色法对167块胃粘膜活检组织进行了幽门螺旋菌(HP)观察,总检出率62.28%。对HP与人群的易感性、解剖学部位、组织学部位及胃病变的关系进行了比较和分折,提示:50岁以下人群可能为易感人群:HP对胃粘膜有直接的致病作用,可能为活动性慢性胃炎及胃溃疡的重要致病因素。但不能提示与胃癌的发生有直接的病因学关系 The Helicobacter pylori (HP) of 167 gastric mucosal biopsy tissues were observed by MB staining with a total detection rate of 62.28%. The relationship between HP and population susceptibility, anatomic sites, histological sites and gastric lesions were compared and analyzed, suggesting that: people under 50 years of age may be susceptible to: HP on the gastric mucosa has a direct pathogenic role, May be active chronic gastritis and gastric ulcer important virulence factors. But can not prompt a direct etiological relationship with the occurrence of gastric cancer
