Inflammatory bowel disease (IBD) is a chronic, nonspecific inflammation of the intestines that primarily comprises Crohn's disease and ulcerative colitis. The incidence and prevalence of IBD have been increasing globally, highlighting the significance of research and prophylactic interventions. Virofree, a mixture of various botanical extracts (including grapes, cherries, olive leaves, marigolds, green tea, and others), has shown significant potential in disease prevention. This study examined the effects of Virofree on intestinal inflammation and the gut microbiota in mice using a dextran sulfate sodium (DSS)-induced model. The mice showed no adverse reactions when administered Virofree. Virofree administration reduced the disease activity index as indicated by amelioration of DSS-induced symptoms in the mice, including weight loss, diarrhea, and rectal bleeding. Regarding the gut microbiota, Virofree intervention modulated the DSS-induced decrease in gut microbial diversity; the Virofree group showed no increase in the phyla or while displaying an increase in the genus , bacteria that may have protective properties. These findings suggest that Virofree may have a direct or indirect impact on the composition of the gut microbiota and that it can alleviate the imbalance of the microbiome and intestinal inflammation caused by DSS treatment.
炎症性肠病(IBD)是一种肠道的慢性非特异性炎症,主要包括克罗恩病和溃疡性结肠炎。IBD的发病率和患病率在全球范围内一直在上升,凸显了研究和预防性干预措施的重要性。Virofree是一种由多种植物提取物(包括葡萄、樱桃、橄榄叶、万寿菊、绿茶等)混合而成的物质,已显示出在疾病预防方面的巨大潜力。本研究使用葡聚糖硫酸钠(DSS)诱导的模型,研究了Virofree对小鼠肠道炎症和肠道微生物群的影响。给小鼠施用Virofree时未观察到不良反应。Virofree给药降低了疾病活动指数,表现为DSS诱导的小鼠症状得到改善,包括体重减轻、腹泻和直肠出血。关于肠道微生物群,Virofree干预调节了DSS诱导的肠道微生物多样性降低;Virofree组在门或纲水平上没有增加,而在属水平上显示出增加,这些细菌可能具有保护特性。这些发现表明,Virofree可能对肠道微生物群的组成有直接或间接影响,并且可以减轻DSS治疗引起的微生物群和肠道炎症的失衡。
