Abstract
ABSTRACTThe present study aimed to evaluate the protective effect of fresh fruit juice of Opuntia dillenii Haw. (FJOD) on acetic acid–induced ulcerative colitis in rats. Fresh FJOD (2.5 and 5 ml/kg) and sulfasalazine (100 mg/kg) were given orally for seven consecutive days prior to colitis induction on the eighth day by intrarectal acetic acid (4% v/v) administration. Macroscopic, clinical activity scoring, biochemical, and histopathological examinations of colon were used to assess colonic damage. FJOD and sulfasalazine treatment significantly attenuated the macroscopic damage, clinical activity score, and wet weight of the colon when compared to disease control and further showed significantly reduced levels of myeloperoxidase, malondialdehyde, and serum lactate dehydrogenase and enhanced colonic levels of reduced glutathione. The protective effect of FJOD may be attributed to its antioxidant and anti-inflammatory activities in ulcerative colitis. The observed effects may be due to the presence of phenolics, flavonoids, and betalains in the fruit juice of Opuntia dillenii.
