摘要
目的:研究不同剂量资生汤加减对慢性萎缩性胃炎型(CAG)Wistar大鼠胃分泌功能(胃蛋白酶活性、胃液pH、胃液总酸度和胃结合黏液),血清一氧化氮合酶(NOS)、生长抑素(SS)、前列腺素E2(PGE2)、胃泌素(GAS)及水通道蛋白3(AQP3)、水通道蛋白4(AQP4)表达的影响,探讨资生汤治疗CAG的作用机制。方法:按随机数字表法从90只大鼠中取15只设正常对照组,不予造模;其余75只采用综合因素诱发建立CAG模型后分为模型组、维酶素组及资生汤高、中、低剂量组,均连续治疗60 d。检测胃分泌功能及血清NOS、SS、PGE2、GAS水平和胃窦组织AQP3、AQP4蛋白表达。结果:与模型组比较,资生汤高、中剂量组胃蛋白酶活性、胃液总酸度、胃结合黏液、血清PGE2、GAS水平及胃窦组织AQP3、AQP4蛋白表达显著升高(P<0.05或P<0.01),胃液pH及血清NOS、SS显著降低(P<0.05或P<0.01)。结论:高、中剂量资生汤能显著改善CAG大鼠的胃分泌功能及血清NOS、SS、PGE2、GAS水平和胃窦组织AQP3、AQP4蛋白的表达。
