制备大鼠慢性胃溃疡模型 ,通过增殖细胞核抗原 (PCNA)等指标 ,对半夏泻心汤进行拆方研究 ,观察其对大鼠慢性胃溃疡的治疗作用 ,以便进一步指导临床实践。实验结果表明 ,半夏泻心汤及其拆方各组均有不同程度的调节胃粘膜细胞增殖作用。拆方各组中 ,部分药组之间呈协同的作用趋势 ,部分药组之间呈制约趋势。综合评价其总体疗效 ,以全方组最佳 ,从而印证了仲景组方的合理性和科学性。 To prepare rat chronic gastric ulcer model, and to study the effect of Banxia Xiexin Decoction on chronic gastric ulcer in rats by using proliferating cell nuclear antigen (PCNA) and other indicators to further guide clinical practice. The experimental results show that Banxia Xiexin Decoction and its decomposed formulae have different degrees of regulation of gastric mucosal cell proliferation. Among the disassembled groups, some drug groups showed a synergistic effect and some of the drug groups showed a trend of restriction. Comprehensive evaluation of its overall efficacy, to the best of the entire group, thus confirming the rationality and scientific nature of the Zhongjing group.
