Rosmarinic acid (RA), which is a natural polyphenol, was isolated from Rosmarinus. officinalis L. The aim of this study is to evaluate the effects of rosmarinic acid on liver and kidney antioxidant enzymes and the tissue ultrastructure in aging mice. RA was administrated at a dosage of 50, 100 or 200 mg kg(-1) once a day with a normal control group and an aging control group for 30 days. The li...

The effects of aging and food restriction on the activities and mRNA levels of antioxidant enzymes in rat livers were examined. Rats were fed ad libitum every day (AL) or ad libitum on every other weekday (FR). At 30 months of age, the catalase and glutathione peroxidase activities were lower, whereas the thiobarbituric acid (TBA) value, an index of lipid peroxidation of the AL rats, was higher...

to determine the importance of q 10 h 2 as an antioxidant in cancer, we measured the activity of lipoamide dehydrogenase (q 10 h 2 recycling enzyme) in hl-60 and normal lymphocyte. the cultured cells of hl-60 and human normal lymphocytes were assayed in cell lysate of given number of both hl-60 and normal lymphocyte. the activity of lipoamide dehydrogenase and the protein concentration were det...

The leaf extract of Tamarindus indica L. (T. indica) had been reported to possess high phenolic content and showed high antioxidant activities. In this study, the effects of the antioxidant-rich leaf extract of the T. indica on lipid peroxidation, antioxidant enzyme activities, H2O2-induced ROS production and gene expression patterns were investigated in liver HepG2 cells. Lipid peroxidation an...
