We aimed to investigate the antioxidant effect and the histopathologic changes caused by Gingko biloba on acetic acid-induced colitis. Methods: Totally 22 rats were divided into three groups. Group 1 (n=7) served as the control group. Group 2 (n=7) and Group 3 (n=8) were given 2 ml/day of 4% acetic acid by intracolonic instillation for three days. Gingko biloba (100 mg/kg) was then given only to Group 3 intraperitoneally for three days. Oxidative stress was assessed by determinate tissue and serum malondialdehyde (MDA) levels, and colonic damage was assessed by histologic examination. Results: Depth of necrosis, extent of necrosis, degree of inflammation, extent of inflammation, fibrosis and total histologic scores in Group 2 were significantly higher than in the control group (p<0.05). The same parameters were lower in Group 3 versus Group 2, but the difference was not significant. Tissue and serum MDA levels in Group 2 were significantly higher than Group 1 (p<0.01 and 0.05, respectively). Again, the same parameters in Group 3 were lower than in Group 2, but the difference was not significant statistically. Conclusions: Gingko biloba did not significantly affect histopathological and oxidative stress parameters in experimental colitis.eninfo:eu-repo/semantics/closedAccessAcetic acidColitisGingko bilobaMalondialdehydeOxidative stressArticle173177182169412502-s2.0-34147152265Q3
