2、。造模成功后,健脾化湿颗粒低、中、高剂量组给药浓度分别为1.5、2.5、4.0g/mL(生药),得舒特组给药浓度3mg/mL灌胃给药。每日1次,连续2周,另外两组为不经任何处理的正常组和造模成功的模型组。实验结束免疫组织化学观察结肠标本5一HT水平的变化。结果IBD模型大鼠结肠组织5一HT的水平显著高于正常组(P<0.01);除健脾化湿低剂量组外,各治疗组大鼠结肠组织中5一HT的水平显著低于模型组(P<0.01)。其中,健脾化湿颗粒高剂量组效果明显,与得舒特组差异无统计学意义(P>0.05)。结论健脾化湿颗粒可抑制IBD模型大鼠结肠黏膜
3、5一HT过高表达,明显改善IBD模型大鼠胃肠功能。关键词:肠易激综合征;血清素;健脾化湿颗粒,5一HTdoi:10.3969/i.issn.1671-8348.2014.14.0l1文献标识码:A文章编号:1671-8348(2014)14-1713一O3EffectofJPHSKLonthequantityof5-Hydroxytryptamineofcolonicmucosaofdiarrhea-predominantirritablebowelsyndromeratsZhaoLibo,WangYinghan,LiuYuling,Z
