为了探讨非溃疡性消化不良 (NUD)患者胃液体排空功能与肥大细胞超微结构之间的关系 ,本文对胃液体排空正常组和排空延迟组各 4例NUD患者进行了研究。每例活检胃窦部粘膜 1块 ,行电镜检查 ,观察肥大细胞形态 ,计数细胞内颗粒数和已释放介质颗粒数 ,计算细胞内颗粒面积与细胞总面积之比。结果示NUD患者中排空延迟者肥大细胞脱颗粒增多 ,提示肥大细胞与NUD患者胃液体排空功能关系密切。
In order to investigate the relationship between gastric emptying and mast cell ultrastructure in patients with non-ulcerative dyspepsia (NUD), four gastric NUD patients with normal gastric emptying and emptying delayed groups were studied. Each case of gastric mucosa of a biopsy, line SEM examination of mast cell morphology, count the number of intracellular particles and the number of particles have been released to calculate the intracellular particle area and the ratio of total cell area. The results showed that delayed draining of NUD patients with mast cell degranulation increased, suggesting that mast cells and NUD patients with gastric emptying function is closely related.
