摘要
目的 探讨大鼠实验性胃溃疡自愈期间 ,胰岛胃泌素免疫反应细胞 (gastrin ,G)和生长抑素细胞(somatostatin ,SSorD)的变化。 方法 免疫组织化学ABC技术。 结果 大部分G细胞免疫反应深浅不一 ;溃疡术后 4、10d ,胰岛G细胞面数密度增高 ,与正常或盐水组相比P <0 0 5。D细胞面数密度于 4d增加 ,P <0 0 5。 结论 成年大鼠胰岛细胞呈胃泌素免疫反应阳性 ;胰岛G细胞和D细胞可能以内分泌或旁分泌调节的途径间接或直接参与大鼠实验性胃溃疡修复的过程。
Objective Studies on the changes of gastrin and SS immunoreactive cells in pancreatic islets during experimental gastric ulcer. Methods The immunohistochemical ABC technique was used. Results The gastrin immunoreactive cells were located in most of the pancreatic islet. The mumber of G cells in experimental gastric ulcer group were higher than that of control group on the 4th and 10th day after operation.The D cells raised on the 10th day.Conclusion The present work provides the evidence that the G and D cells of pancreatic islets might be involed in the self-healing process of the experimental gastric ulcer by endocrine or paracrine regulation.
