1Lead Induced Oxidative Stress: Beneficial Effects of Kombucha Tea显示文摘To evaluate the effect of oral administration of Kombucha tea (K-tea) on lead induced oxidative stress. Methods Sprague Dawley rats were administered 1 mL of 3.8% lead acetate solution daily alone or in combination with K-tea orally for 45 d, and the antioxidant status and lipid peroxidation were evaluated. Results Oral administration of lead acetate to rats enhanced lipid peroxidation and release of creatine phosphokinase and decreased levels of reduced glutathione (GSH) and antioxidant enzymes (superoxide dismutase, SOD and glutathione peroxidase, GPx). Lead treatment did not alter humoral immunity, but inhibited DTH response when compared to the control.Lead administration also increased DNA fragmentation in liver. Oral administration of Kombucha tea to rats exposed to lead decreased lipid peroxidation and DNA damage with a concomitant increase in the reduced glutathione level and GPx activity. Kombucha tea supplementation relieved the lead induced immunosuppression to appreciable levels. Conclusion The results suggest that K-tea has potent antioxidant and immunomodulating properties.P.DIPTI B.YOGESH A.K.KAIN T.PAULINE B.ANJU M.SAIRAM B.SINGH S.S.MONGIA G.ILAVAZHAGAN DEVENDRA KUMAR W.SELVAMURTHY 2003Biomedical and Environmental Sciences2003,16,3:6
2沙棘叶子提取物对白化病白鼠由铬诱导氧化胁迫的抗氧化活性评估显示文摘本研究报道沙棘(胡颓子科)对雄性白化病白鼠由铬诱导氧化胁迫的抗氧化活性。氧化胁迫通过对小白鼠进行强制性喂养30 d,以浓度为30 m g/kg的铬相对体重比例的重铬酸钾盐实现。铬促使体重下降,而却明显增加了器官与体重比例。铬处理明显减少了谷胱甘肽的降低,增加了丙二醛和肌氨酸磷酸激酶的水平;而且它还加强了血清中谷氨酸草酰乙酸转移酶和谷氨酸丙酮酸转移酶的浓度。用不同剂量的沙棘叶子提取物(乙醇提取)对保护铬元素诱导的氧化胁迫进行了评估,结果表明叶子提取物在浓度为100到250 m g/kg铬与体重比的情况下可以明显保护动物避免由铬所诱导的氧化伤害。郭海 赵明 S.Geetha M.Sai Ram S.S.Mongia Virendra Singh G.Ilavazhagan R.C.Sawhney 2006陕西林业科技2006,30,1:0
