人体胃粘膜有相对疏水特性,它在保护胃粘膜抵抗胃酸胃蛋白酶的作用方面具有重要意义。由于幽门螺杆菌(HP)具有分解脂肪活性的作用,因此我们研究的目的是检测胃粘膜疏水性的减弱是否因HP感染所致。采取内镜下胃窦粘膜活检,对慢性浅表性胃炎病人进行研究,其中HP(+)30例,HP(-)38例。在胃粘膜表面滴入0.9％盐水后,使用测角计测量接触角作为粘膜疏水性指数。结果显示HP(+)胃炎患者的接触角(平均值士
Human gastric mucosa has a relatively hydrophobic character, which is of great importance in protecting gastric mucosa against gastric acid pepsin. Since Helicobacter pylori (HP) has the effect of breaking down fat activity, the purpose of our study was to determine whether the decrease in gastric mucosal hydrophobicity is due to HP infection. Thirty patients with chronic superficial gastritis were studied by endoscopic mucosal biopsy of antral mucosa, including 30 cases of HP (+) and 38 cases of HP (-). After 0.9% saline was dropped on the gastric mucosal surface, the contact angle was measured as a mucosal hydrophobic index using a goniometer. The results showed that the contact angle of HP (+) gastritis patients (mean ± s)
