2、拉唑各剂量组于化疗前30min尾静脉注射相应药物。化疗6h后,检测各组大鼠胃液的pH值、胃液和胃组织中顺铂的含量,并进行胃组织病理学观察。结果:正常对照组胃液pH值为2.7±0.35,与其比较,模型组胃";eLpH值明显降低,胃组织损伤严重(P<0.05);与模型组比较,奥美拉唑各剂量组胃液的pH值明显升高,顺铂含量明显减少(P<0.05或P<0.01),但胃组织中顺铂含量无明显变化,胃组织损伤明显减轻(P<0.05),且与剂量呈正相关,但各剂量组间差异无统计学意义。结论:奥美拉唑对顺铂致胃损伤具有一定的保护作用,可能是通过降低胃液pH值和减少胃液中顺铂含量来实现的;
3、且在一定范围内,奥美拉唑的保护作用与剂量呈正相关。关键词奥美拉唑;顺铂;大鼠;胃损伤;保护作用ProtectiveEfectsofOmeprazoleonCisplatinInducedGastricInjuryinRatsCHENXuan.ying,PENGXiao-ping,WANGLin,WEIXiao—hua,WANYue—sheng(TheFirstAfiliatedHospi—talofNanchangUniversity,Nanchang330006,China)LIWen-juan(StateKeyLaboratoryofFoodScienceandT
