Ulcerative colitis is a chronically recurrent inflammatory bowel disease of unknown origin in which oxidative stress has been implicated. The main aim of the present study was to evaluate possible protective effect of alcoholic extract of Aloe Vera against the drug induced model of colitis in rats. Induction of colitis by colonic administration of drugs(Acetic acid, Indomethacin and TNBS) cause severe microscopic inflammation of colon after 24 hrs of administration of one of any above inducing agent, as assessed by the macroscopically. Microscopically colonic tissue showed ulceration, oedema and inflammatory cell infiltration. Biochemical estimation studies revealed decrease in serum levels of lactate Dehydrogenase (LDH) may be due to increase in Colonic concentration of tumor necrosis factor α (TNF- α) and neutrophill infiltration index. Oxidative stress was indicated by reduced glutathione concentration (GSH) as well as increase in levels of lipid peroxidase (LPO) and myeloperoxidase (MPO) activity in colonic tissue. Pretreatment with Aloe Vera extract at a dose of (400mg/kg/day, orally),10 days before induction of colitis increase level of serum LDH and GHS, while colonic concentration of LPO and MPO was increased. It also showed decrease in macroscopic score. The findings of the present study provide evidence that Aloe Vera extract may be beneficial in inflammatory bowel disease.
