葎草醇提物对小鼠分泌性腹泻作用的影响

Effect on Humulus scandens Alcohol Extract on Secretory Diarrhea of mice

为了探讨葎草醇提物对小鼠分泌性腹泻的治疗作用,本试验采用番泻叶灌胃法制作小鼠腹泻模型,通过观察小鼠精神变化、体重变化、DAI评分、结肠肠壁厚度及小肠病理切片变化的情况,评价葎草醇提物对小鼠的抗腹泻作用。结果显示,与模型组相比,葎草醇提物对治疗组小鼠精神恢复、体重及小肠绒毛恢复等均有明显的作用;治疗组相对模型组体重有上升趋势,但仍不能完全恢复至正常水平;治疗组与模型组相比DAI评分明显降低,且与空白组相比DAI评分差异不显著(P>0.05);治疗组肠壁厚度较模型组差异显著(P<0.05),治疗效果显著。病理组织学观察,空白组小鼠小肠绒毛排列整齐,各层次结构清晰,绒毛间质无水肿、无小血管扩张充血,而模型组小鼠小肠绒毛排列紊乱,大部分绒毛脱落,绒毛表面有炎性渗出,绒毛间质水肿,小血管扩张、充盈。治疗组与模型组相比症状明显改变,小肠绒毛排列整齐,绒毛表面炎性渗出大部分消失,绒毛间质无明显水肿、无小血管扩张、充血,小肠结构与正常组织大致相同,治疗效果明显。研究结果表明葎草醇提物对小鼠腹泻有明显的治疗效果,可为分泌性腹泻的治疗提供理论依据。

To explore the therapeutic effect of Humulus scandens alcohol extract on secretory diarrhea in mice,we used lavage of senna to produce diarrhea mice mode.The mental state,body weight,colon intestinal wall thickness and histopathological changes were observed daily during the experiment period and the disease activity index was detected to evaluated therapeutic action of Humulus scandens alcohol extract on diarrhea.The results showed that compared with model group,the treatment group had significant effects on metal state,body weight and small intestinal villus recoveries;Compared with model group,body weight of treatment group had a rising trend but still couldn＇t reach the normal level.The DAI of treatment group decreased compared with model grope,there was no significant difference between blank group and treatment group（P〉0.05）.Compared with model group,intestinal wall thickness of treatment group were significant differences（P〈0.05）,the treatment effect was remarkable.Histological examination showed that in blank group,small intestinal villus was neatly,the hierarchical structure was clear,and there was no small vessel hyperemia and no villous intestinal edema.While small intestinal villus of model group disordered,most of the villus fell off,there was inflammation exudation on the surface of villi,villous edema and congestion of small blood vessels.Compared with model group,symptoms of treatment group significantly changed,which showed greatly reduced cell inflamma-tory exudation,there was no obvious edema and congestion in villi interstitial,small intestinal structure was roughly the same as normal tissue,the treatment effect was obvious.Humulus scandens alcohol extract had significant therapeutic effect on diarrhea in mice,and could provide a theoretical basis for the treatment of secretory diarrhea.
