Abstract
The role of antioxidant N-acetyl-L-cysteine (NAC) in protection against cellular changes triggered by maneb during in vitro exposure was investigated in cultured Chinese hamster V79 cells. We observed high apoptotic activity and high oxidative stress induced by exposure to maneb evidenced by a statistically significant increase in lipid peroxidation (measured as TBARS – thiobarbituric acid reactive substances) as well as a decrease of glutathione (GSH) and glutathione disulfide (GSSG) ratio (GSH/GSSG). Maneb did not exhibit any effect on protein oxidation (measured by protein carbonyls content). NAC suppressed cellular changes induced by maneb in V79 cells. NAC pre-treatment prevented TBARS production and significantly decreased the number of apoptotic cells. However, protective effect of NAC on GSH and GSSG levels has been shown only in cells exposed to lower concentration of maneb (100 μM).
