泻热汤与硝菔汤为常用中药复方,都具有攻积导泻作用,但临床应用不同。本文采用肠套叠还纳作用、导泻作用、肠蠕动功能及肠容积称重等指标,对两方进行了研究与比较。结果证明,两方均有肠套叠还纳作用;泻热汤的导泻作用强于硝菔汤;泻热汤有明显的促进肠蠕动功能;两方又都能增加肠容积。在治疗肠套叠过程中,硝菔汤毒性大于泻热汤,其机理及临床效果有待进一步探讨。 Diarrhea soup and Nitrate Soup are commonly used traditional Chinese medicine formulas, and they all have the role of accumulating diarrhea, but their clinical application is different. In this paper, we used intussusception, catharsis, catgut peristalsis and intestinal volume measurement to study and compare the two methods. The results showed that both sides had intussusception and remission; diarrhea hot soup has a stronger cathartic effect than nitroguanidine; diarrhea fever soup has a significant role in promoting bowel movement; both parties can increase bowel volume. In the treatment of intussusception, Nitrate decoction is more toxic than diarrhea fever soup, its mechanism and clinical effects remain to be further explored.
