Abstract

Inflammatory bowel diseases (IBD), which include Crohn's disease and ulcerative colitis, manifest as a result of intricate interactions involving genetic predisposition, environmental factors, intestinal microbiota dynamics, and immune dysregulation, ultimately leading to persistent mucosal inflammation. Addressing this complex pathology requires a nuanced understanding to inform targeted therapeutic strategies. Consequently, our study explored the viability of Aged Garlic Extract (AGE) as an alternative therapeutic regimen for IBD management. Utilizing gas chromatography-mass spectrometry (GC-MS) and scanning electron microscopy (SEM), we characterized AGE, revealing distinctions from Fresh Garlic Extract (FGE), particularly the absence of allicin in AGE and accompanying structural alterations. In experiments employing an IBD rat model, AGE intervention exhibited remarkable antioxidant, antibacterial, and anti-inflammatory properties. Noteworthy outcomes included improved survival rates, mitigation of intestinal damage, restoration of gut microbial diversity, reinforcement of tight junctions, and reversal of mitochondrial dysfunction. Collectively, these effects contributed to the preservation of enterocyte integrity and the attenuation of inflammation. In conclusion, the unique chemical composition of AGE, coupled with its substantial influence on gut microbiota, antioxidant defenses, and inflammatory pathways, positions it as a promising adjunctive therapy for the management of IBD. These observations, synergistically considered with existing research, provide significant insights into the potential utility of AGE in addressing the intricate pathophysiology inherent to IBD. The potential strength of study and rationale of using AGE against IBD includes exploring alternative therapeutic regimens if conventional treatments are associated with side effects, identification of potential hotspots/pathways involved in disease progression and study can provide economically cheaper and naturally occurring alternative to patient community who are struggling to afford expensive medications. These promising findings underscore the necessity for additional investigations to ascertain the feasibility of clinical translation, thereby substantiating the potential therapeutic role of AGE in the management of IBD.

摘要

炎症性肠病(IBD)包括克罗恩病和溃疡性结肠炎,是由遗传易感性、环境因素、肠道微生物群动态变化和免疫失调等复杂相互作用导致的,最终会引发持续的黏膜炎症。要解决这种复杂的病理问题,需要有细致入微的理解,以便制定有针对性的治疗策略。因此,我们的研究探讨了陈年大蒜提取物(AGE)作为一种用于IBD治疗的替代疗法的可行性。利用气相色谱 - 质谱联用仪(GC - MS)和扫描电子显微镜(SEM),我们对AGE进行了表征,发现其与新鲜大蒜提取物(FGE)存在差异,特别是AGE中不含大蒜素以及随之而来的结构变化。在使用IBD大鼠模型的实验中,AGE干预表现出显著的抗氧化、抗菌和抗炎特性。值得注意的结果包括提高存活率、减轻肠道损伤、恢复肠道微生物多样性、加强紧密连接以及逆转线粒体功能障碍。总的来说,这些作用有助于维持肠上皮细胞的完整性并减轻炎症。总之,AGE独特的化学成分,加上其对肠道微生物群、抗氧化防御和炎症途径的重大影响,使其成为IBD治疗中一种有前景的辅助疗法。将这些观察结果与现有研究协同考虑,可以深入了解AGE在解决IBD固有复杂病理生理学方面的潜在效用。研究使用AGE治疗IBD的潜在优势和原理包括:如果传统治疗伴有副作用,探索替代治疗方案;确定疾病进展中涉及的潜在热点/途径;该研究可为难以负担昂贵药物的患者群体提供经济上更便宜且天然存在的替代方案。这些有前景的发现强调了进行更多研究以确定临床转化可行性的确必要性,从而证实AGE在IBD治疗中的潜在治疗作用。
