Effect of HJE and PEP on inflammation in WAS colon. Histological comparison of the WAS colon at day 11. Stained colon sections in normal group (a), WAS group (b), loperamide 5 mg/kg + WAS group (c), HJE 0.25 mL/kg + WAS (d), HJE 0.5 mL/kg + WAS (e), PEP 0.25 mL/kg + WAS (f), and PEP 0.5 mL/kg + WAS (g) were observed and representative images of each section were captured at ×100 magnification. Effect of HJE and PEP on TNF-α concentration (h), FRAP value (i), and TBARS value (j) on WAS colon. Data were expressed as mean ± SEM (n = 6). versus normal group; and versus WAS group.
