| Organophosphate (OP) pesticides such as dichlorvos (DDVP) intoxication has been shown to produce oxidative stress due to the generation of free radicals, which alter the antioxidant defense system in erythrocytes. In this study, the effects of DDVP (1, 10, 100 µM) or DDVP + vitamin C (VC; 10 µM) or vitamin E (VE; 30 µM), on the levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities in human erythrocytes were examined in vitro. There were no statistical differences between all groups for 1 µM concentration of DDVP. Treatment with DDVP alone produced an increase in the level of MDA and decreased activities of antioxidant enzymes (P < 0.05). Groups treated with vitamins and DDVP showed... |

| ABSTRACTThe aim of this work was to assess the damage of DNA in human blood cell and spermin vitro under the influence of furan. These cells were administered 0-600 μM of furan at 37 and 32oC for 30 and 60 min, respectively. A significant increase in tail DNA%, tail length and moment indicating DNA damage was observed at increasing doses when compared to the controls. The treatment with 300 and 600 μM of furan showed a maximum increase of 86.74 ± 2.43 and 93.29 ± 8.68 compared to the control tail DNA% in lymphocytes. However, only 600 μM of furan showed a maximum increase of 94.71 ± 6.24 compared to the control tail DNA% in sperm. The results suggested that furan caused DNA damage in lymphocytes at increasing doses, but appeared to have not the same effect... |

| ABSTRACT Organophosphorous pesticides (OPs) posses a great potential of acute toxicity for exposed animals and men. To evaluate the toxic potential of the organophosphate diazinon on root meristematic cells of Allium cepa L., was created two groups: In group 1 (control group), was not given any chemical. In group 2 (diazinon-treatment group), different doses (10, 40, 80 and 160 ppm) and times periods (24, 48 and 72 h) were administered. After exposure, cell death, effective concentration (EC50), mitotic index, cellular /chromosome aberrations, DNA damage by comet assay and RAPD-PCR were assessed at exposure times. EC50 value of diazinon was detected approximately 80 ppm. Hyperchromasia, later segragation, micronucleus, pulverised nucleus, nuclear... |

| Furan is a food and environmental contaminant and a potent carcinogen in animals. Lycopene is one dietary carotenoid found in fruits such as tomato, watermelon and grapefruit. The present study was designed to explore the protective effect of lycopene against furan-induced oxidative damage in streptozotocin (STZ)-induced diabetic rat kidney. At the end of the experimental period (28 days), we found that lycopene markedly decreased the malondialdehide (MDA) levels in the kidney, urea, uric acid and creatinine levels in the serum of furan-treated rats. The increase of histopathology in the kidney of furan-treated rats were effectively suppressed by lycopene. Furthermore, lycopene markedly restored superoxide dismutase (SOD), catalase (CAT), glutathione... |
