摘要
目的探讨金钱草总黄酮提取液抑制大鼠草酸钙结石形成机制的研究。方法常规饲养大鼠1周,采用乙二醇饮水和氯化铵灌胃造模草酸钙结石大鼠模型,将30只SD大鼠随机分为空白对照组(A组)、草酸钙结石模型组(B组)和金钱草总黄酮组(C组)。给药4周后收集各组大鼠24 h尿液,检测尿p H值及24 h尿钙、尿草酸、尿酸、尿葡胺聚糖和尿凝血酶原片段-1的含量。结果金钱草总黄酮组大鼠24 h尿量较草酸钙结石模型组增加,差异有统计学意义(P<0.05),与空白对照组比较差异无统计学意义(P>0.05)。金钱草总黄酮组大鼠与草酸钙结石模型组大鼠比较,其24 h尿钙和尿草酸含量均降低,而尿凝血酶原片段-1的含量增加,差异均有统计学意义(P<0.05)。而三组间尿p H值、尿酸经比较均无明显差异(P>0.05)。结论金钱草总黄酮提取液可能通过增加大鼠24 h尿量,降低尿液中成石因子-尿钙和尿草酸的含量,增加尿液中抑石因子-尿凝血酶原片段-1含量,从而抑制草酸钙结石的形成。
