The antioxidant effect of soymilk fermented by HFY01 (screened from yak yogurt) was investigated on mice with premature aging induced by D-galactose. antioxidant results showed that HFY01-fermented soymilk (LP-HFY01-DR) had better ability to scavenge the free radicals 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) diammonium salt (ABTS) than unfermented soymilk and -fermented soymilk. Histopathological observation showed that LP-HFY01-DR could protect the skin, spleen and liver, reduce oxidative damage and inflammation. Biochemical results showed that LP-HFY01-DR could effectively upregulate glutathione (), catalase (), superoxide dismutase (), and glutathione peroxidase () levels and decrease malondialdehyde () content in the liver, brain, and serum. Real-time quantitative reverse transcription polymerase chain reaction further showed that LP-HFY01-DR could promote the relative expression levels of the genes encoding for cuprozinc superoxide dismutase (), manganese superoxide dismutase (), , and in the liver, spleen, and skin. High-performance liquid chromatography results revealed daidzin, glycitin, genistin, daidzein, glycitein, and genistein in LP-HFY01-DR. In conclusion, LP-HFY01-DR could improve the antioxidant capacity in mice with premature aging induced by D-galactose.
研究了由HFY01(从牦牛酸奶中筛选得到)发酵的豆浆对D-半乳糖诱导的早衰小鼠的抗氧化作用。抗氧化结果表明,HFY01发酵豆浆(LP-HFY01-DR)比未发酵豆浆和其他发酵豆浆具有更好的清除1,1-二苯基-2-苦基肼(DPPH)和2,2'-联氮-双-(3-乙基苯并噻唑啉-6-磺酸)二铵盐(ABTS)自由基的能力。组织病理学观察表明,LP-HFY01-DR可以保护皮肤、脾脏和肝脏,减少氧化损伤和炎症。生化结果表明,LP-HFY01-DR可以有效上调肝脏、大脑和血清中的谷胱甘肽()、过氧化氢酶()、超氧化物歧化酶()和谷胱甘肽过氧化物酶()水平,并降低丙二醛()含量。实时定量逆转录聚合酶链反应进一步表明,LP-HFY01-DR可以促进肝脏、脾脏和皮肤中编码铜锌超氧化物歧化酶()、锰超氧化物歧化酶()、 和 的基因的相对表达水平。高效液相色谱结果显示LP-HFY01-DR中含有大豆苷、黄豆黄素、染料木苷、大豆苷元、黄豆黄素和染料木黄酮。总之,LP-HFY01-DR可以提高D-半乳糖诱导的早衰小鼠的抗氧化能力。
