title: The antioxidant effects of vitamin A, C, and E on aflatoxin B1-induced oxidative stress in human lymphocytes.
abstract: The aim of this study was to investigate the possible protective role of vitamin A, C, and E on aflatoxin B(1)-induced in human lymphocytes using biochemical approaches. The control group received dimethyl sulfoxide, the second group of cultures were administered aflatoxin B(1) (AFB(1)) at a dose of 5 muM. The other group of cultures were treated with AFB(1)+vitamin A (0.5 and 1.0 and 1.5 microM) and AFB(1)+vitamin C (25, 50, and 100 microM) and AFB(1)+vitamin E (40, 100, and 200 microM). The results of this experiment show that AFB(1) significantly decreased the level of GSH and the activities of superoxide dismutase and GPx and increased level of malondialdehyde. Simultaneous supplementation with vitamin A, C, and E restored these parameters to that of normal range. In conclusion, vitamin A, C, and E exhibited protective effects in human lymphocytes by inhibiting AFB(1)-induced ROS generation.
