The gut microbiota, which can be highly and dynamically affected by dietary components, is closely related to IBD pathogenesis. Here, we demonstrated that food-grade glycerol monolaurate (GML)-mediated enhancement of Bifidobacterium and fecal SCFAs could be responsible for the anticolitis effect.

  Objective: The objective of this research was to investigate the anti-inflammatory effect of Mahkota Dewa fruit pericarp extract (Phaleria macrocarpa) on inducible nitric oxide synthase (iNOS) in mice colon induced by dextran sodium sulfate (DSS).Method: The simplisia of P. macrocarpa pericarp was weighed (1000 g) and extracted by maceration process. The total yield of the ethanolic extract was 26.43%. Phytochemical screening was carried out for the detection of the phytoconstituents by simple qualitative methods. The anti-inflammatory activity was performed by DSS-induced colitis model through assessment of hematoxylin-eosin staining and expression of iNOS by immunohistochemistry assay at four different doses, i.e., 650, 1250, 2500, and 5000 mg/kg. Swiss Webster male mice weighing 25-30 g were used for the study.Results: Inflammation score in dose 625, 1250, 2500, and 5000 mg/kg were 1.63, 1.43, 1.32, and 2.20, respectively. This result is significantly different (p=0.008) with DSS group that was 4.37. The results of iNOS optical density score in dose 625, 1250, 2500, and 5000 mg/kg were 1.21, 1.119, 1.22, and 1.37, respectively. This result was significantly different (p=0.000) with DSS group that was 2.24.Conclusion: Pericarp extract of P. macrocarpa fruit exhibited anti-inflammatory activity in the experimental model shown by suppressing the expression of inflammatory cell and iNOS.

Background/Aims: There are known links between inflammatory bowel disease (IBD) and changes in the microbiota of the gut and inflammation and oxidative stress. In this study, a colitis model induced by dextran sodium sulfate (DSS) in mice is used to evaluate whether the presence of bioactive peptides IRW (Ile-Arg-Trp) and IQW (Ile-Gln-Trp) peptides is advantageous. Methods: The mice were arbitrarily assigned to the following four groups: (i) control (untreated), (ii) dextran sodium sulfate (DSS) treated, (iii) IRW-DSS treated, and (iv) IQW-DSS treated. For 7 days, the control group subjects had unrestricted access to untreated drinking water, whereas the drinking water supplied to the subjects in the DSS, IRW-DSS, and IQW-DSS groups during this period consisted of 5% DSS solution. The colonic lesions were scored after hematoxylin and eosin staining. Serum antioxidant capacity was analyzed by 2,2’-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical cation decolorization test and the microbiota in the colonic contents were sequenced by HiSeq2500 PE250. Results: The presence of DSS reduced daily weight gain, enhanced histopathology scores, and inhibited antioxidant enzyme expression. Superoxide dismutase, catalase, and glutathione peroxidase activities in the DSS-induced colitis model were significantly enhanced (P < 0.05) in the presence of dietary IRW and IQW. Furthermore, the Simpson index was significantly increased (P < 0.05) in the presence of dietary IRW and IQW compared to the control group. IRW and IQW increased the abundance of Coprococcus_1, Ruminococcaceae_UCG-014, and Desulfovibrio compared to the control group and DSS group. Furthermore, IQW decreased the abundance of Bacteroides in relation to the control group, but increased Parabacteroides. In addition, IRW increased the level of Anaerotruncus, Oscillibacter, and Ruminiclostridium_9 compared to the control group. Conclusion: This study concludes that the presence of IRW or IQW can mitigate DSS-induced oxidative stress by improving the activities of antioxidant enzymes, increasing intestinal microbial diversity and enhancing the abundance of gut microbiota, which may help maintain the homeostasis of host health and microenvironment in a DSS-induced mouse model, thus providing a potential further treatment for IBD patients.

The role of non-steroidal anti-inflammatory drugs in inflammatory bowel disease is controversial, as they have been implicated in disease aggravation. Different from other cyclooxygenase inhibitors, acetylsalicylic acid (ASA) enhances the formation of anti-inflammatory and proresolution lipoxins derived from arachidonic acid as well as resolvins from omega-3 polyunsaturated fatty acids such as docosahexaenoic acid (DHA). In this study, we examined the effect of ASA on murine dextran sodium sulfate colitis. A mouse magnetic resonance imaging (MRI) protocol and post mortem assessment were used to assess disease severity, and lipid metabolites were measured using liquid chromatography-coupled tandem mass spectrometry. Decreased colitis activity was demonstrated by phenotype and MRI assessment in mice treated with ASA, and confirmed in postmortem analysis. Analysis of lipid mediators showed sustained formation of lipoxin A4 and an increase of DHA-derived 17-hydroxydocosahexaenoic acid (17-HDHA) after treatment with ASA. Furthermore,in vitroexperiments in RAW264.7 murine macrophages demonstrated significantly increased phagocytosis activity after incubation with 17-HDHA, supporting its proresolution effect. These results show a protective effect of ASA in a murine colitis model and could give a rationale for a careful reassessment of ASA therapy in patients with inflammatory bowel disease and particularly ulcerative colitis, possibly combined with DHA supplementation.
