Abstract

Background

Gastric ulcer is one of the most common gastrointestinal tract diseases with a higher extent in male patients to. Selenium nanoparticles (SeNPs) possess therapeutic benefits, including antimicrobial, antioxidant, anti-inflammatory, and anti-ulcerative agents. The study aimed to investigate the modulatory effect of yeast-mediated SeNPs on gastric ulcers and microbiota dysbiosis in a rat model.

Method

Twenty-four rats were randomly divided into four groups. Both the control and SeNPs-only groups received distilled water orally, and after 1 h, they received 2 % carboxymethyl cellulose (CMC). The ulcer model and SeNPs-treated groups received 99 % ethanol (5 ml/kg orally) for ulcer induction, followed by 2 % CMC after one hour. The SeNPs-treated group got SeNPs (60 mg/kg) suspended in 2 % CMC. We measured ulcer markers (ulcer index and gastric juice pH and volume and stomach tissue oxidative stress markers (malondialdehyde (MDA), glutathione (GSH), nitric oxide (NO), and catalase (CAT)), in addition to histopathological examination of gastric tissues stained with three different satins: hematoxylin-eosin (H&E), periodic acid-Schiff (PAS), and Masson's trichrome stains (many-color dye), and microbiological analysis of freshly collected fecal sample.

Results

SeNPs treatment significantly decreased gastric volume, ulcer index, malondialdehyde, and increased glutathione levels. A macroscopic examination of the treated stomach revealed decreased ulcer lesion numbers. Furthermore, histopathological examination showed that SeNPs treatment repaired ulcerative gastric tissue through the regeneration of epithelial cells and reduction in damaged areas and collagen fibers. In the treated group, microbiological analysis of rat feces showed a significant increase in Leuconostoc pseudomesenteroides, Escherichia coli, and Enterococcus faecium counts.

Conclusion

This research suggests that SeNPs exhibit anti-ulcer activity and can accelerate ulcer healing via their antioxidant action. They also have a modulatory effect on gut microbiota dysbiosis associated with gastric ulcers. This is the first research studying the impact of safe yeast-mediated SeNPs on rat's gastric ulcer and gut microbiota.

酵母介导的SeNPs对雄性白化大鼠胃溃疡愈合和肠道菌群失调的影响

背景胃溃疡是最常见的胃肠道疾病之一，在男性患者中发病率较高。硒纳米颗粒（SeNPs）具有治疗作用，包括抗菌、抗氧化、抗炎和抗溃疡剂。本研究旨在探讨酵母介导的SeNPs对大鼠胃溃疡和微生物群失调的调节作用。方法24只大鼠随机分为4组。对照组和纯senps组均口服蒸馏水，1 h后给予2 %羧甲基纤维素（CMC）。溃疡模型组和senps处理组大鼠灌胃99 %乙醇（5 ml/kg）诱导溃疡，1 h后再灌胃2 % CMC。SeNPs处理组SeNPs（60 mg/kg）悬浮在2 % CMC中。我们测量了溃疡标志物（溃疡指数、胃液pH值和体积）和胃组织氧化应激标志物（丙二醛（MDA）、谷胱甘肽（GSH）、一氧化氮（NO）和过氧化氢酶（CAT）），此外还对三种不同染色剂（苏木精-伊红（H&；E）、周期性酸-希夫（PAS）和马森三色染色剂）染色的胃组织进行了组织病理学检查，并对新鲜收集的粪便样本进行了微生物学分析。结果senps治疗显著降低胃容量、溃疡指数、丙二醛和谷胱甘肽水平。经治疗的胃的宏观检查显示溃疡病变数量减少。此外，组织病理学检查显示，SeNPs处理通过上皮细胞的再生和受损区域和胶原纤维的减少来修复溃疡性胃组织。在治疗组中，对大鼠粪便的微生物分析显示，假肠杆菌、大肠杆菌和屎肠球菌计数显著增加。结论SeNPs具有抗溃疡活性，可通过其抗氧化作用促进溃疡愈合。它们对与胃溃疡相关的肠道微生物群失调也有调节作用。这是首次研究安全酵母介导的SeNPs对大鼠胃溃疡和肠道微生物群的影响。

期刊介绍： Tissue and Cell is devoted to original research on the organization of cells, subcellular and extracellular components at all levels, including the grouping and interrelations of cells in tissues and organs. The journal encourages submission of ultrastructural studies that provide novel insights into structure, function and physiology of cells and tissues, in health and disease. Bioengineering and stem cells studies focused on the description of morphological and/or histological data are also welcomed. Studies investigating the effect of compounds and/or substances on structure of cells and tissues are generally outside the scope of this journal. For consideration, studies should contain a clear rationale on the use of (a) given substance(s), have a compelling morphological and structural focus and present novel incremental findings from previous literature.
