本研究用对免疫荧光染色,对32例胃十二指肠溃疡患者胃窦胃泌素细胞和生长抑素产生细胞进行研究。发现:十二指肠溃疡患者G细胞数量增加,而且G细胞分泌功能增强,致使产生更多的胃泌素引起胃酸增高:D细胞数量没有减少,G/D比值与正常对照组比较无差异,提示D细胞数量的增减在十二指肠溃疡的形成中并不一定起决定性作用。 In this study, we used immunofluorescence staining to study gastric antrum gastrin cells and somatostatin-producing cells in 32 patients with gastroduodenal ulcer. Findings: The number of G cells in patients with duodenal ulcers increased, and the secretion of G cells increased, resulting in more gastrin caused by increased gastric acid: the number of D cells did not decrease, G/D ratio compared with the normal control group, no difference, It is suggested that the increase or decrease of the number of D cells does not necessarily play a decisive role in the formation of duodenal ulcers.
