【摘要】 <正> 虽然目前已比较普遍使用纤维胃镜早期诊断胃、十二指肠疾病,但测定胃液分泌功能特别是游离酸排出量仍然是必要的常规检查方法之一。胃游离酸的排出量与壁细胞数及其分泌功能状态有关。壁细胞分泌受神经及体液因素的支配。在安静状态下仅有部分壁细胞进行分泌活动,基础胃液就是测定在安静状态下受试者一小时胃液分泌量及游离酸排出量(以下简更多还原

【Abstract】 Basal gastric secretion was studied in 175 normal subjects, 150 cases of duodenal ulcer and 119 cases of gastric ulcer.In normal subjects the volume of basal gastric secretion was not more than 100ml/hr and the basal acid output was below 3mEq/hr. Basal gastric secretion in male was higher than that in female.Basal gastric secretion volume and acid output in patients with duodenal ulcer was obviously higher than that in normal subjects. If BAO was more than 10mEq/hr, it was diagnostic for duodenal ulcer.The BAO in gastric ulcer patients showed slightly higher level than that in normal subjects, but it was not significant statistically. And there was no significant difference between male and female gastric ulcer patients too.The BAO was found to be zero in 7.3% of patients with duodenal ulcer, this fact indicates that the diagnosis of active duodenal ulcer can not be ruled out even if BAO is zero.更多还原
