EC细胞是消化道主要的内分泌细胞之一.该细胞分泌的5—羟色胺等生物活性物质入血或经旁分泌直接或间接调节胃肠功能活动.这些调节作用是影响胃溃疡愈合修复的重要因素.有关EC细胞在消化性溃疡疾病时的形态学研究并不多见.笔者在原工作基础上进行了实验:用成年雄性Vastar大鼠78只,分为溃疡组、盐水组和正常对照组,在手术后4、6、10、14、21及28天分批取材,用免疫细胞化学PAP法显示胃窦粘膜含5—HT的细胞,光镜下观察大鼠实验性胃溃疡自愈过程中5—羟
The EC cell is one of the major endocrine cells of the digestive tract. The serotonin and other biologically active substances secreted by this cell enter the blood or undergo side-secretion to directly or indirectly regulate gastrointestinal function. These regulatory effects are important factors influencing the healing of gastric ulcer. The morphological studies of EC cells in peptic ulcer disease are rare. The authors conducted an experiment based on the original work: 78 adult male Vastar rats were divided into ulcer group, saline group, and normal control group. After 4, 6, 10, 14, 21, and 28 days after surgery, the rats were obtained in batches and 5-HT cells in the antral mucosa were visualized by immunocytochemistry PAP. The rats were observed under a light microscope for the self-healing process of experimental gastric ulcer. 5 -hydroxyl
