    摘要:

    以鼠李糖乳杆菌GG(LGG)为对照菌株,研究了自行分离鉴定的母乳婴儿源益生菌植物乳杆菌BF_15的体外抗氧化活性、安全性与缓解DSS诱导小鼠结肠氧化损伤的症状。结果表明:试验菌株植物乳杆菌BF_15能够耐受高浓度的H2O2(3.5 mmol/L)。发酵上清液中,菌株BF_15对DPPH的清除能力低于对照菌株LGG(P<0.01);对·OH清除能力高于LGG(P<0.05);对·O2-清除能力高于LGG(P>0.05);抗脂质过氧化能力低于LGG(P<0.01)。菌悬液中,菌株BF_15对DPPH和·O2-的清除能力高于对照菌株LGG(P>0.05);对·OH清除能力高于LGG(P<0.01);抗脂质过氧化能力低于LGG(P<0.01)。试验菌株BF_15与对照菌株LGG均不产生有害代谢产物(生物胺、亚硝酸盐、吲哚),不具有溶血性。动物实验中,菌株BF_15通过早期灌胃小鼠,减轻了小鼠肠黏膜损伤及炎症细胞浸润的程度,提高了超氧化物歧化酶(SOD)活性(P<0.01),降低了丙二醛(MDA)含量(P<0.01),进而有效缓解了DSS诱导小鼠结肠氧化损伤的症状,其效果与对照菌株LGG相当(P>0.05)。本研究为来自人体母乳婴儿源益生菌的开发、应用及其早期干预缓解溃疡性结肠炎(Ulcerative colitis,UC)等肠道疾病提供了科学依据,也为氧化应激作为治疗UC等肠道疾病的新靶点提供了借鉴指导。

    Abstract:

    In this study,with Lactobacillus rhamnosus GG (LGG) as control strain,probiotic probiotic Lactobacillus plantarum BF_15,isolated from breast milk infant,was used as the research object to evaluate its antioxidant activity in vitro,safety and alleviation of the DSS-induced oxidative damage in the colon of mice.The results show that the test strain Lactobacillus plantarum BF_15 could tolerate high concentrations of H2O2 (3.5 mmol/L).In the fermentation supernatant,the scavenging ability of strain BF_15 on DPPH was lower than that of the control strain LGG (P<0.01);the scavenging ability of oOH was higher than LGG (P<0.05);the scavenging ability of ·O2- was higher than LGG (P>0.05);anti-lipid peroxidation ability was lower than LGG (P<0.01).In the bacterial suspension,the scavenging ability of strain BF_15 on DPPH and ·O2- was higher than that of the control strain LGG (P>0.05);the scavenging ability on ·OH was higher than LGG (P<0.01);the anti-lipid peroxidation ability was lower than LGG (P<0.01).Meanwhile,Neither the test strain BF_15 nor the control strain LGG produced harmful metabolites (bioamine,nitrite,indole),and had hemolytic properties.In animal experiments,the strain BF_15 could reduce the degree of intestinal mucosal damage and inflammatory cell infiltration,increase the activity of superoxide dismutase (SOD) (P<0.01),and reduce the level of malondialdehyde (MDA) content (P<0.01) through early intragastric administration,which effectively alleviated the symptoms of DSS-induced oxidative damage in the colon of mice;its effect was equivalent to that of the control strain LGG (P>0.05).This study provided a scientific basis for the development and application of probiotics derived from human breast milk infants and their early intervention to relieve intestinal diseases such as ulcerative colitis(UC).This study laid a solid foundation for probiotics in the prevention of intestinal diseases such as ulcerative colitis (UC),and provided a reference guide for oxidative stress as a new therapeutic target.
