ABSTRACT

<p><b>OBJECTIVE</b>To explore the effects of Huoxiang Zhengqi liquid (HXZQ) on enteric mucosal immune responses in mice with Bacillus dysenteriae and Salmonella typhimurium induced diarrhea (BSD).</p><p><b>METHOD</b>Mice were randomly divided into four groups with 10 mice in each group: control group (control), BSD group, Huoxiang Zhengqi liquid treated BSD groups at high dosage and low dosage (HXZQ high, HXZQ low). HXZQ was administrated from the day of diarrhea induction at dosage of 5.21 g kg(-1) and 0.52 g kg (-1) respectively. Peyer's patch and periphery lymphocytes were prepared for flow cytometry, and level of TNF-alpha in periphery and enteric tissue homogenate were determined with ELISA. Student's t-test was used for statistics.</p><p><b>RESULT</b>Mice in BSD group started showing continuous diarrhea at the day of induction till the fourth day when the mice were sacrificed. Diarrhea in the mice of HXZQ high and low groups lasted for 36 and 54 h respectively. There were more CD4+ and CD8+ cells in periphery, less CD4+ cells in peyer's patch in BSD mice comparing to normal mice. In peyer's patch, there were more CD8+ cells in mice in HXZQ high and low groups and more CD4+ in mice in HXZQ high group. Higher level TNF-alpha in periphery and intestinal tissue homogenate in BSD group were observed. Mice in HXZQ high group showed the decreased level TNF-alpha in periphery and enteric tissue homogenate.</p><p><b>CONCLUSION</b>The immune regulation on peyer's patch CD4+ and CD8+ cells and suppression on TNF-alpha level in enteric homogenate might partially explain the effect of HXZQ on improvement of BSD.</p>
