Ulcerative colitis belongs to inflammatory bowel diseases, which really is a band of chronic disorders from the gastrointestinal system. vitro experiments, n indicates the number of animals used in the experiment Rabbit polyclonal to PAX9 (one sample per animal was obtained for each MPO activity measurement, qPCR, hematoxylin and eosin (H&E) stain, FITC experiment, and Isc measurement). Statistical analyses were performed using Prism 8.0 (GraphPad Software Inc., La Jolla, CA, USA). The data are expressed as means SEM. For the analysis of the effects on ion transport, colon permeability, and expression of TJs, FFARs, and pro-inflammatory cytokines, a one-way ANOVA was performed followed by NewmanCKeuls post hoc assessments. Ordinal data were analyzed by KruskalCWallis one-way analysis of variance. Values of 0.05 were considered statistically significant. 3. Results 3.1. WO Diet Does Not Cause Excessive Body Weight Gain in Mice and Alleviates Symptoms of DSS-Induced Colitis Mice at 4 weeks of age were randomly assigned to three groups fed with either SD, SO, or WO diet, and their BW was recorded for 8 weeks (measurement every 4 days) (Physique 2A). Since day 16, there was no significant difference between groups (Physique 2A). Open in a separate window Body 2 Data for bodyweight adjustments (A) in mice given with standard diet plan (SD), SD supplemented with sunflower essential oil (SO), and SD supplemented with walnut essential oil (WO). Data for bodyweight loss throughout dextran sulfate sodium (DSS) treatment (B) and general change in bodyweight after seven days of colitis (C). Data signify indicate SEM, n = 28 per group (A); n Chelerythrine Chloride kinase activity assay = 8 per group (B,C); * 0.05, ** 0.01, *** 0.001, when compared with SD; ## 0.05, when compared with SD + DSS. On time 48 from the test, the plain tap water was became the 3% DSS option. After seven days of colitis, the biggest BW reduction was seen in SD + DSS group (Body 2A,B). Treatment with Thus and WO considerably reduced BW reduction (Body 2B). On time 7, mice had been sacrificed, the macroscopic rating was performed, as well as the tissues for both histological assay and rt-PCR evaluation were collected. We discovered that DSS treatment elevated the macroscopic rating considerably, stool rating, and reduced the colon duration and colon fat in all groupings (Body 3ACompact disc). The WO-enriched diet plan could alleviate the result of DSS, while SO just elevated the colon duration. Interestingly, the digestive tract fat/duration proportion was restored in the WO group totally, Chelerythrine Chloride kinase activity assay as there was no difference compared to the control group (Physique 3E). MPO activity was increased in both SD + DSS and SO + DSS groups comparing to controls, while WO + DSS did not differ significantly from non-inflamed mice (Physique 3F). Open in a separate window Physique 3 The anti-inflammatory effect of sunflower oil (SO) and walnut oil (WO) in a mouse model of colitis induced by DSS. Physique shows the data for macroscopic score (A), stool score (B), colon length (C), colon excess weight (D), colon excess weight/colon length ratio (E), and myeloperoxidase (MPO) activity (F). Data symbolize imply SEM, n = 8. * 0.05, ** 0.01, *** 0.001, as compared to control; # 0.05, ## 0.01, ### 0.001 as compared to DSS; $$ 0.01, as compared to sunflower oil (SO). Histological assessment of mouse colon samples supported the macroscopic observations (Physique 4). Chelerythrine Chloride kinase activity assay Analysis revealed intact epithelium, normal muscle architecture, and an absence of edema in the control group (Physique 4A). Microscopic damage, characterized by the loss of mucosal architecture, the presence of crypt abscesses, the thickening of easy muscle, as well as widespread cellular infiltration was observed in SD + DSS as well as SO + DSS groups (Physique 4B,C). WO prevented colon damage, as examined microscopically (Physique 4D) and in the histological score (Physique 4E).
