[PMID: 34912469 PMCID: PMC8668319 DOI: 10.1155/2021/9945244] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 08/27/2021] [Accepted: 10/07/2021] [Indexed: 01/11/2023]
Abstract
Background. Ulcerative colitis is a worldwide chronic gastrointestinal disease characterized by variable extensions of colon mucosal inflammation. The available drugs have an incomplete response with various side effects and socioeconomic impacts. Aloe barbadensis Miller (Aloe vera) is a well-known medicinal plant with diverse pharmacological and therapeutic activities. As a result, in the current study, Aloe vera was selected to evaluate its therapeutic effects on experimental colitis in rats. Methods. This study is intended to evaluate the possible beneficial effect of Aloe vera for the treatment of experimental colitis. Trinitrobenzenesulfonic acid (TNBS) was used to induce experimental colitis in 60 of 70 Wistar rats. The rats were grouped in 7 clusters including healthy control, negative, positive control (received sulfasalazine), and test groups treated with Aloe vera extracts via oral or rectal routes. Macroscopic and histologic factors as well as the biochemical parameters were evaluated on day 7. Results. In the present study, it was found that serum levels of tumor necrosis factor-α (75 vs. 44 pg./ml), interleukin-6 (41 vs. 21 pg/ml), and nitric oxide (24 vs. 6 μm/ml) in TNBS-induced untreated colitis treatment were significantly increased as compared to healthy control. Similar patterns were also observed in malondialdehyde (76.41 vs. 236.35 μg/mg) and myeloperoxidase (4.24 vs. 29.38 U/mg) in colonic tissue. Among different treatments, rectal administration of Aloe vera extract (400 mg/kg) exhibited the best result in which serum concentration of tumor necrosis factor-α (55 pg/ml), interleukin-6 (24 pg/ml), and nitric oxide (10 μm/ml) and the levels of malondialdehyde (102.67 μg/mg), as well as myeloperoxidase (12.29 U/mg) in colon tissue, were reduced as compared to the untreated group. Also, the body weight and colon weight/length ratios were more improved in the treated group with 400 mg/kg Aloe vera extract, rectally. Conclusion. Aloe vera extract exhibited a therapeutic effect in TNBS-induced colitis, and local, rectal administration of Aloe vera extract was more effective than oral administration.

Abstract
AbstractThis study was done to investigate the synergistic impacts hydro extract of jujube fruit in combination with Mesalazine (orally) and Asacol (intra-colonic) administration in ameliorating animal model of ulcerative colitis (UC). After the induction of UC and with the development of signs, the treatment groups daily received the hydro extract of jujube fruit (200 mg/kg, orally, enema), Mesalazine (30 mg/kg, orally) and Asacol (10 mg/kg, enema). After 10 days, rats were euthanized and were studied. Findings indicated a significant increase in Myeloperoxidase (161.66 ± 10.40), Nitric oxide (216.01 ± 17.55), IL-6 (138.54 ± 7.02), and TNF-α (123.87 ± 9.80) colon tissue levels and pathological damage of positive control group compared with the negative control group. Hydro extract of jujube fruit in combination with Mesalazine (orally) and Asacol (intra-colonic) group represented a higher capability in significantly decreasing Myeloperoxidase (73.33 ± 9.07), Nitric oxide (81.66 ± 10.50), IL-6 (51.69 ± 5.19), TNF-α (30.59 ± 5.50) levels and pathological damage in compared with the other treatment groups. Considering accessibility and affordability of jujube fruit and the side effects of routine drugs, taking a combination of jujube fruit with low doses of routine pharmaceutical drugs can improve and cure ulcerative colitis disease.

Abstract
AbstractUlcerative 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.

Abstract
Abstract
Objective To investigate the effects of hydroalcoholic extract of Ziziphus jujuba on the histopathological, tissue oxidative stress and inflammation plus to antioxidant pathways of colon tissue in rat with induced Ulcerative colitis.
Materials and methods Ulcerative colitis was induced in 80 rats those divided into 8 equal groups. Group 1 and 2 were negative controls receiving 1 mL/day of normal saline in enema and oral; group 3 and 4 as positive control 1 and 2 received 10 mg/kg of intra-colonic asacol and oral mesalazine; groups 5 and 6 received 20% and 40% of hydroalcoholic extract of Z. jujuba trans-rectally; group 7 and 8 received 1500 and 3000 mg/kg of hydroalcoholic extract of Z. jujuba orally, respectively. After 7 days, animals were evaluated for colon tissue histopathology, levels of malondialdehyde and IL-1β, and activities of superoxide dismutase, glutathione peroxidase and myeloperoxidase in colon tissue.
Results Hydroalcoholic extract of Z. jujuba in both forms of trans-rectal and oral administration especially in the higher doses could result into a more healing effect in damaged colonic tissue, more reduce glutathione peroxidase and IL-1β level. Also, these two doses (gel 40% and oral 3000 mg/kg) could more decrease the myeloperoxidase activity and stimulate superoxide dismutase and glutathione peroxidase activities. Also, gel 40% in transrectal administration was more potent than administration 3000 mg/kg in oral.
Conclusion The results of the present study indicated that Z. jujube may be considered as a treatment of choice for Ulcerative colitis especially in gel form and also in dose-dependent pattern.

The Antioxidant and Anti-Inflammatory Effects of Quercus brantii Extract on TNBS-Induced Ulcerative Colitis in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:3075973. [PMID: 33505492 PMCID: PMC7808820 DOI: 10.1155/2021/3075973] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 11/15/2020] [Accepted: 12/19/2020] [Indexed: 12/16/2022]
Abstract
Objectives Ulcerative colitis is a common subtype of persistent inflammatory bowel disease with high morbidity consequences. Despite unknown definite pathogenesis, multiple anti-inflammatory medications are used for its treatment. Traditionally, Quercus brantii (QB), mostly available in the Middle East, has been used for gastrointestinal disorders. Other beneficial effects associated with QB include reduction of oxidative stress, inflammations, homeostatic instability, and improvement in clinical conditions. Materials and Methods This experimental study was designed to assess the possible therapeutic effects of QB on UC and compare its effects with those of sulfasalazine. Of the 70 Wistar rats clustered in seven groups, ten received only alcohols and sixty were confirmed to be suffering from trinitrobenzene sulfonic acid- (TNBS-) induced colitis. Four groups received different dosages of QB extract via oral and rectal routes, one received sulfasalazine, and the other remaining two groups received nothing. The effects of QB were evaluated by assessing macroscopic and histologic scoring, measuring inflammatory mediators, and determining oxidative stress markers. Results Comparing to the untreated TNBS-induced control groups, QB-treated groups showed a dose- and route-dependent improvement comparable with sulfasalazine. Treating rats with QB reduced the microscopic and macroscopic damage, decreased TNF-α, IL-6, NO, MPO activity, and MDA content, increased superoxide dismutase (SOD) activity, and reduced body weight loss. Conclusions Our data recommended the anti-inflammatory and antioxidant effects of QB extract in a dose-dependent manner.

Abstract
Inflammatory bowel disease (IBD) is a chronic and life-long disease characterized by gastrointestinal tract inflammation. It is caused by the interplay of the host's genetic predisposition and immune responses, and various environmental factors. Despite many treatment options, there is no cure for IBD. The increasing incidence and prevalence of IBD and lack of effective long-term treatment options have resulted in a substantial economic burden to the healthcare system worldwide. Biologics targeting inflammatory cytokines initiated a shift from symptomatic control towards objective treatment goals such as mucosal healing. There are seven monoclonal antibody therapies excluding their biosimilars approved by the US Food and Drug Administration for induction and maintenance of clinical remission in IBD. Adverse side effects associated with almost all currently available drugs, especially biologics, is the main challenge in IBD management. Natural products have significant potential as therapeutic agents with an increasing role in health care. Given that natural products display great structural diversity and are relatively easy to modify chemically, they represent ideal scaffolds upon which to generate novel therapeutics. This review focuses on the pathology, currently available treatment options for IBD and associated challenges, and the roles played by natural products in health care. It discusses these natural products within the current biodiscovery research agenda, including the applications of drug discovery techniques and the search for next-generation drugs to treat a plethora of inflammatory diseases, with a major focus on IBD.
