Fig. 2. Histomorphological characteristics of atractylodin-induced anti-inflammatory effects on DP and CP rats.

Panel A: the histology images including normal jejunal tissue, CP jejunal tissue, DP jejunal tissue, CP+Atrac jejunal tissue, and DP+Atrac jejunal tissue. Panel B: statistical analysis of the effects of atractylodin on the serum contents of TNF-α, IL-1β and IL-6 in both DP and CP rats. Data are expressed as mean±SD (% NC, n=6); ^**p<0.01 compared with the normal controls; ^##p<0.01 compared with CP group or DP group before being given Atractylodin, respectively. Atrac, atractylodin; NC, normal control rats; CP, constipation prominent rats; DP, diarrhea prominent rats.
