【摘要】 目的 :研究注射用兰索拉唑对大鼠实验性胃溃疡的影响。方法 :采用大鼠出血休克性胃溃疡、水浸应激性胃溃疡及幽门结扎性胃溃疡模型 ,观察兰索拉唑静脉注射对损伤胃粘膜的保护作用。结果 :兰索拉唑 15 - 6 0mg/kg事先给药 ,对 3种胃溃疡模型都有明显的抑制溃疡形成作用 ,且有良好的量效关系。在同等剂量下兰索拉唑和奥美拉唑的抗溃疡作用无显著差异 ,但对水浸应激性胃溃疡的疗效明显强于后者 (P <0 0 1)。结论 :兰索拉唑静脉注射明显抑制大鼠实验性胃溃疡的形成。更多还原

【Abstract】 AIM:To investigate the effect of lansoprazole on gastric ulceration in rats. METHODS:Using the gastric ulcer model induced by hemorrhagic shock, restraint water-immersion stress and pylorus-ligature, the protective effect of lansoprazole (iv) on gastric ulceration was observed. RESULTS: Pretreatment with lansoprazole (7.5-60 mg/kg) significantly inhibited the formation of gastric ulcer in the three models in a dose-dependent manner. The autiulcer efficacy of lansoprazole was similar to that of omeprazole in the equal dose, but stronger than that of omeprazole for ulcer induced by water-immersion stress. CONCLUSION: The intravenously administered lansoprazole inhibited formation of experimental gastric ulcer in rats.更多还原
