应用放射免疫分析法(RIA),测定了30例活动性胃溃疡(GU)患者在抗溃疡治疗前后胃液表皮生长因子(EGF)含量,探讨 EGF 在 GU 发生和愈合中的作用。一、资料与方法30例活动期 GU 患者均经胃镜及病理组织学检查证实,其中男18例,女12例,年龄26～60岁,平均35.8岁。正常对照组20例为因上腹不适做胃镜检查者,但胃镜及组织学检查无异常发现,男13例,女7例,年龄20～51岁,平均34.7岁。所有 Radioimmunoassay (RIA) was used to determine the content of epidermal growth factor (EGF) in gastric juice of 30 patients with active gastric ulcer (GU) before and after anti-ulcer treatment, and to explore the role of EGF in the occurrence and healing of GU. First, the data and methods 30 active GU patients were confirmed by gastroscopy and histopathological examination, including 18 males and 12 females, aged 26 to 60 years, mean 35.8 years. Twenty patients in the normal control group were gastroscopy because of upper abdominal discomfort. However, there were 13 males and 7 females, aged 20-51 years (mean 34.7 years) with no abnormal findings of gastroscopy and histology. all
