大黄黄连泻心汤、理中丸对幽门结扎型、醋酸涂抹型胃溃疡寒热证模型大鼠血清NT含量的影响

目的：建立幽门结扎型及醋酸涂抹型胃溃疡寒热证动物模型,阐明寒热方剂（大黄黄连泻心汤、理中丸）的作用机制及方证相应规律,为临床辨治溃疡病提供实验依据。同时,为以“病证结合”模式之中医证型研究提供方法学新途径。方法：采用寒热因素结合幽门结扎、醋酸涂抹法,分别建立大鼠胃溃疡寒、热证模型,采用酶联免疫法检测受试大鼠血清NT的含量。结果：幽门结扎及醋酸涂抹型胃溃疡各模型组大鼠血清NT含量均显著降低,与空白组比较具有显著性差异（P〈0.05或P〈0.01）,其中醋酸涂抹型胃溃疡模型中以热证降低显著,与寒醋和模醋比较差异显著（P〈0.01）;大黄黄连泻心汤可显著升高热性溃疡组大鼠血清NT含量,理中丸可显著升高寒性溃疡组大鼠血清NT的含量（P〈0.05或P〈0.01）。结论：通过“方证相应”理论验证了“病证结合”的胃溃疡寒热模型复制成功,大黄黄连泻心汤对热性胃溃疡、理中丸对寒性胃溃疡的治疗作用,可通过大鼠血清中NT含量的升高而实现。
