ABSTRACT Ulcerative colitis is a chronic inflammatory condition of the colon with an unknown etiology. In this study, we aimed to evaluate the therapeutic effects of Cupressus sempervirens extract on the healing of acetic acid-induced ulcerative colitis in rat. Fifty-five male rats divided into five equal treatment groups were used for this study and received the following treatments: Group 1, 250 mg/kg asacol; Group 2, 1 ml gel base (carboxymethyl cellulose); Group 3, 0.5% gel form of C. sempervirens extract; Group 4, 1% gel form of C. sempervirens extract, and; Group 5, considered as negative control and received 1 ml of normal saline. Body weight changes, histopathological and antioxidant changes in the colon tissue were evaluated. Significant weight gain was observed in rats that received 1% gel extract of C. sempervirens. Significant superoxide dismutase activity was also detected in 0.5 and 1% gel extract groups compared to C. sempervirens extract, Asacol and in 1% gel extract groups compared to the gel base group. Furthermore, both gel extract groups had significant lower total antioxidant capacity compared to Asacol group. Several histopathological lesions including inflammation, ulceration, crypt disarray, and goblet cell depletion were detected in the different groups, however, the mean rank of pathological changes showed no significant difference among the five groups. In summary, our results showed that hydroalcoholic extracts of C. sempervirens leaves produces healing effects in acetic acid induced ulcerative colitis.
