Inhibitory effects of patchouli alcohol on stress-induced diarrhea-predominant irritable bowel syndrome

Figure 3 Inhibitory effects of patchouli alcohol on contractions induced by high extracellular KCl levels in isolated colonic longitudinal smooth muscle. Mechanical recording (A to D) and histogram (E) of relaxation effect of PA (100 μmol/L) on colonic contractions induced by high extracellular KCl levels in IBS-D rats [KCl-treated control group A: n = 27 , KCl-treated IBS-D group B: n = 23, PA + KCl-treated control group C: n = 8, PA + KCl-treated IBS-D group D: n = 8. ^aP < 0.05 vs KCl-treated control group, ^dP < 0.01 vs KCl-treated IBS-D group; unpaired t-test]. Data are expressed as mean ± SE.
