Abstract
Pomegranate seed oil shows positive effects by limiting neutrophil activation and lipid peroxidation through its antioxidant and anti-inflammatory activities. This study evaluated the possible ameliorative effects of pomegranate seed oil, its actions on proinflammatory cytokines, and its antioxidant activity using an acute acetic acid-induced colitis model in rats. 32 male Sprague-Dawley rats were divided into 4 groups: control, colitis, 0.4 ml/kg, and 0.8 ml/kg pomegranate seed oil treatment after colitis. At the end of the experiment, histopathological and biochemical analyses of intestinal tissues and blood were performed. The study revealed that administering different doses of pomegranate seed oil dramatically reduced total oxidant levels, nuclear factor kappa B, proinflammatory cytokines, and myeloperoxidase activity and appreciably reduced colitis injury. These findings suggest that pomegranate seed oil may alleviate colitis symptoms effectively and exert protective effects through antioxidant, anti-inflammatory mechanisms.

Abstract
Inflammatory bowel disease (IBD) is a chronic immune-mediated condition that affects the digestive system and includes Crohn's disease (CD) and ulcerative colitis (UC). Although the exact etiology of IBD remains uncertain, dysfunctional immunoregulation of the gut is believed to be the main culprit. Amongst the immunoregulatory factors, reactive oxygen species (ROS) and reactive nitrogen species (RNS), components of the oxidative stress event, are produced at abnormally high levels in IBD. Their destructive effects may contribute to the disease's initiation and propagation, as they damage the gut lining and activate inflammatory signaling pathways, further exacerbating the inflammation. Oxidative stress markers, such as malondialdehyde (MDA), 8-hydroxy-2'-deoxyguanosine (8-OHdG), and serum-free thiols (R-SH), can be measured in the blood and stool of patients with IBD. These markers are elevated in patients with IBD, and their levels correlate with the severity of the disease. Thus, oxidative stress markers can be used not only in IBD diagnosis but also in monitoring the response to treatment. It can also be targeted in IBD treatment through the use of antioxidants, including vitamin C, vitamin E, glutathione, and N-acetylcysteine. In this review, we summarize the role of oxidative stress in the pathophysiology of IBD, its diagnostic targets, and the potential application of antioxidant therapies to manage and treat IBD.

Abstract
Ulcerative colitis (UC), an inflammation of the colon lining, represents the main form of inflammatory bowel disease IBD. Nutritional therapy is extremely important in the management of ulcerative colitis. Fish oil contains long-chain omega-3 polyunsaturated fatty acids, which have beneficial effects on health, including anti-inflammatory effects. This study aims to investigate the benefits of bluefin tuna oil extracted by the Soxhlet method in vitro by determining the anti-radical and anti-inflammatory activities and in vivo by evaluating the preventive and curative effects. The experiments were carried out using two doses of oil (100 and 260 mg/kg) and glutamine (400 and 1000 mg/kg) on the acetic acid-induced UC model. UC has been induced in Wistar rats by intrarectal administration of a single dose of 1 mL acetic acid (5% v/v in distilled water). The obtained results indicate that tuna oil and glutamine have a significant anti-free radical effect. Tuna oil has a marked anti-inflammatory power based on membrane stabilization and inhibiting protein denaturation. The reduction of various UC parameters, such as weight loss, disease activity score DAS, and colonic ulceration in rats pre-treated with tuna oil and glutamine, demonstrate that these treatments have a significant effect on UC. Total glutathione GSH, superoxide dismutase SOD, and catalase activities are significantly restored in the tuna oil and glutamine groups, while lipid peroxidation has been markedly reduced.

Abstract
Pomegranate seed oil, extracted from pomegranate seeds, is a slightly fragrant yellow oil with a mild odor. Pomegranate seed oil is the main source of punicic acid (conjugated linolenic acid). Punicic acid is a long-chain omega-5 polyunsaturated fatty acid and a conjugated α-linolenic acid molecule. This acid is thought to provide many health benefits. This study evaluated the potential of pomegranate seed oil to attenuate damage to liver and kidney tissues in an acetic acid-induced colitis model. 32 male Sprague-Dawley rats were divided into 4 groups: control, colitis, 0.4 ml/kg, and 0.8 ml/kg pomegranate seed oil treatment after colitis. At the end of the experiment, histopathological and immunohistochemistry analyses of liver and kidney tissues were performed. Pomegranate seed oil treatment reduced damage in liver and kidney tissues, suppressed NF-κB activation, and regulated apoptosis. These findings support the potential effects of pomegranate seed oil against extraintestinal symptoms of colitis through its anti-inflammatory, and anti-apoptotic properties.

Abstract
Background: Ulcerative colitis is a chronic immune-mediated inflammatory bowel disease that involves inflammation and ulcers of the colon and rectum. To date, no definite cure for this disease is available. Objective: The objective of the current study was to assess the effect of Calliandra haematocephala on inflammatory mediators and oxidative stress markers for the exploration of its anti-ulcerative colitis activity in rat models of acetic acid-induced ulcerative colitis. Methods: Methanolic and n-hexane extracts of areal parts of the plant were prepared by cold extraction method. Phytochemical analysis of both extracts was performed by qualitative analysis, quantitative methods, and high-performance liquid chromatography (HPLC). Prednisone at 2 mg/kg dose and plant extracts at 250, 500, and 750 mg/kg doses were given to Wistar rats for 11 days, which were given acetic acid on 8th day through the trans-rectal route for the induction of ulcerative colitis. A comparison of treatment groups was done with a normal control group and a colitis control group. To evaluate the anti-ulcerative colitis activity of Calliandra haematocephala, different parameters such as colon macroscopic damage, ulcer index, oxidative stress markers, histopathological examination, and mRNA expression of pro and anti-inflammatory mediators were evaluated. mRNA expression analysis was carried out by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR). Results: The phytochemical evaluation revealed polyphenols, flavonoids, tannins, alkaloids, and sterols in both extracts of the plant. Results of the present study exhibited that both extracts attenuated the large bowel inflammation and prevented colon ulceration at all tested doses. Macroscopic damage and ulcer scoreswere significantly decreased by both extracts. Malondialdehyde (MDA) levels and nitrite/nitrate concentrations in colon tissues were returned to normal levels while superoxide dismutase (SOD) activity was significantly improved by all doses. Histopathological examination exhibited that both extracts prevented the inflammatory changes, cellular infiltration, and colon thickening. Gene expression analysis by RT-qPCR revealed the downregulation of pro-inflammatory markers such as tumor necrosis factor-alpha (TNF-α) and cyclooxygenase-2 (COX-2) whereas the anti-inflammatory cytokines including Interleukin-4 (IL-4) and Interleukin-10 (IL-10) were found to be upregulated in treated rats. Conclusion: It was concluded based on study outcomes that methanolic and n-hexane extracts of Calliandra haematocephala exhibited anti-ulcerative colitis activity through modulation of antioxidant defense mechanisms and the immune system. In this context, C. haematocephala can be considered as a potential therapeutic approach for cure of ulcerative colitis after bioassay-directed isolation of bioactive phytochemicals and clinical evaluation.

Abstract
Ethnopharmacological relevance Ginger (Zingiber officinale Roscoe) has been used for food and applied in Ayurvedic medicine in India for thousands of years. With a reputation for strong anti-inflammatory properties, it has been used for to treat colds, migraines, nausea, arthritis, and high blood pressure in China and Southeast Asia. The physiological activity of ginger is attributed to its functional components, including gingerol and shogaol, and their derivatives. Aim of the study We aimed to investigate the effects of 8- and 10-shogaol and their bioactive signaling mechanisms in a dextran sodium sulfate (DSS)-induced colitis mouse model. The anti-colitis efficacy of 6-, 8-, and 10-derivatives of gingerol and shogaol was comparatively analyzed. Materials and methods Colitis was induced by providing mice with drinking water containing 5% DSS (w/v) for 8 days. The 6-, 8-, and 10-derivatives of gingerol and shogaol were orally administered for two weeks at a dose of 30 mg/kg. Changes in body weight and disease activity index were measured. The levels of pro-inflammatory cytokines, iNOS and COX-2, as well as the phosphorylation of NF-κB were analyzed using ELISA, PCR, or western blotting. Mucin expression and mRNA levels were measured using alcian blue staining and PCR, respectively. The tight-junction-associated proteins occludin and ZO-1 were assessed using immunohistological staining. Results The 6-, 8-, and 10-derivatives of gingerol and shogaol exhibited anti-inflammatory effects by regulating NF-κB signaling. Among the compounds administered, 10-shogaol was the most effective against DSS-induced inflammation. Comparative analysis of the chemical structure showed that shogaol, a dehydrated analog of gingerol, was more effective. 6- and 10-shogaol showed similar effects on DSS-induced morphological changes in the colonic mucus layer, mucin expression, and tight junction proteins. Conclusions 6-, 8-, and 10-Gingerol and 6-, 8-, and 10-shogaol significantly improved the clinical symptoms and intestinal epithelial barrier damage in DSS-induced colitis in mice. The derivatives effectively inhibited DSS-induced inflammation through the regulation of NF-κB signaling. Moreover, 10-shogaol showed the most potent anti-inflammatory effect among the six compounds used in this study. The results indicate that 8- and 10-shogaol, both main ingredients in ginger, may serve as therapeutic candidates for the treatment of colitis.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is characterized with chronic inflammation of gastrointestinal track. In the pathogenesis of IBD, inflammation is the main mechanism. Induction of inflammation triggers the oxidative stress that subsequently leading to apoptosis. Considering the all pathological mechanisms, many therapeutic agents have been used for IBD but because of serious side effects there is still a need for new therapeutic drugs. In this study, we aim to evaluate the possible protective effects of Theranekron (TH) on acetic acid (AA)- induced colonic damage and to describe the probable effect mechanisms of TH. MATERIALS AND RESULTS Fourty female adult Wistar albino rats were divided into 5 groups. Following 24 h fasting, colitis was induced by rectal instillation of AA. In TH group, a single dose of subcutaneous 0.2 ml TH was used. In treatment groups, 0.2 ml TH single dose or 100 mg/kg sulfasalazine (SS) for 7 days were used after colitis induction. Normal salin was used for all applications in control group. Histopathologically hemorrhage, edema and inflammatory reactions were seen in AA group. TH and SS decreased the severity of lesions. Nuclear factor kappa B, Serum amyloid A, C-reactive protein, Growth-related oncogene, and Osteopontin expressions were markedly increased in AA group and TH markedly reduced these expressions. In Western analysis, decreased NF-kB and caspase-3 levels were observed with TH. Oxidative markers did not changed significantly. CONCLUSIONS TH has a prominent anti-inflammatory effect on AA-induced colonic inflammation via NF-kB signaling whereas antiapoptic effects seem to be independent from this pathway.
