Alcoholic liver diseases are classified as one of the major reasons for worldwide morbidity and mortality. Curcuminoids exhibit a wide range of pharmacological activities that are beneficial for health, including hepatoprotective effects, but its clinical significance is limited due to poor oral bioavailability. In the present study, a novel formulation of curcumin as curcumin-galactomannosides (CGM) with enhanced oral bioavailability alleviated alcohol-induced liver damage in wistar rats with an increased potency compared to the unformulated natural curcuminoids (CM). Ethanol administration significantly elevated liver toxicity markers, lipid peroxidation and inflammatory markers with a simultaneous reduction in antioxidant defenses. Supplementation of CGM reversed all of the pathological effects of alcohol administration, almost close to the normal level, when compared with CM. Histopathology of liver tissue also confirmed the better protective effect of CGM, indicating the enhancement in antioxidant and anti-inflammatory effects as a function of bioavailability.
酒精性肝病被列为全球发病率和死亡率的主要原因之一。姜黄素类化合物具有广泛的有益于健康的药理活性,包括肝保护作用,但由于口服生物利用度差,其临床意义有限。在本研究中,一种新型姜黄素制剂姜黄素-半乳甘露聚糖(CGM)具有增强的口服生物利用度,与未成型的天然姜黄素类化合物(CM)相比,其缓解酒精引起的大鼠肝损伤的效力增加。乙醇给药显著升高肝毒性标志物、脂质过氧化和炎症标志物,同时降低抗氧化防御。与 CM 相比,CGM 的补充逆转了酒精给药的所有病理作用,几乎接近正常水平。肝组织病理学也证实了 CGM 的更好的保护作用,表明作为生物利用度的函数的抗氧化和抗炎作用增强。
