α-Galacto-oligosaccharides have been reported to have beneficial health effects. The purpose of this study was to investigate the preventive effects of a newly synthesized α-galacto-oligosaccharide mixture (α-GOSg), as well as raffinose family oligosaccharides (RFOs), on dextran sulfate sodium (DSS)-induced colitis in mice. When administered in drinking water at 0.5% for 15 days, both α-GOSg and RFOs significantly decreased fecal hemoglobin content, partially prevented colon length shortening, reduced the severity of colon inflammation, and attenuated DSS-induced upregulation of cyclooxygenase-2. In addition, the activation of the inflammatory regulator nuclear factor-kappa B was slightly inhibited by α-GOSg. The results showed that the newly synthesized α-GOSg preparation has similar anti-inflammatory activities as RFOs in this colitis model. The anti-inflammatory activity of α-GOSg in humans remains to be investigated.
α-半乳糖寡糖已被报道具有有益的健康影响。本研究的目的是研究一种新合成的 α-半乳糖寡糖混合物（α-GOSg）以及棉子糖家族寡糖（RFOs）对葡聚糖硫酸钠（DSS）诱导的小鼠结肠炎的预防作用。当以 0.5%的浓度添加到饮用水中并连续饮用 15 天时，α-GOSg 和 RFOs 均显著降低粪便血红蛋白含量，部分预防结肠缩短，减轻结肠炎症的严重程度，并减弱 DSS 诱导的环氧合酶-2 的上调。此外，α-GOSg 轻微抑制了炎症调节剂核因子-κB 的激活。结果表明，在这种结肠炎模型中，新合成的 α-GOSg 制剂具有与 RFOs 相似的抗炎活性。α-GOSg 在人类中的抗炎活性仍有待研究。
