Terzi A, Iraz M, Sahin S, Ilhan A, Idiz N, Fadillioglu E: Protective effects of erdosteine on rotenone-induced oxidant injury in liver tissue. Toxicol Ind Health. 2004 Sep;20(6-10):141-7.
Rotenone, an insecticide of botanical origin, causes toxicity through inhibition of complex I of the respiratory chain in mitochondria. This study was undertaken to determine whether rotenone-induced liver oxidant injury is prevented by erdosteine, a mucolytic agent showing antioxidant properties. There were four groups of Male Wistar Albino rats: group one was untreated as control; the other groups were treated with erdosteine (50 mg/kg per day, orally), rotenone (2.5 mg/mL once and 1 mL/kg per day for 60 days, i.p.) or rotenone plus erdosteine, respectively. Rotenone treatment without erdosteine increased xanthine oxidase (XO) enzyme activity and also increased lipid peroxidation in liver tissue (P < 0.05). The rats treated with rotenone plus erdosteine produced a significant decrease in lipid peroxidation and XO activities in comparison with rotenone group (P < 0.05). Erdosteine treatment with rotenone led to an increase in catalase (CAT) and superoxide dismutase (SOD) activities in comparison with the rotenone group (P < 0.05). There was no significant difference in nitric oxide (NO) level between groups. There were negative correlations between CAT activity and malondialdehyde (MDA) level (r = -0.934, P < 0.05) with between CAT and SOD activities (r = -0.714, P < 0.05), and a positive correlation between SOD activity and MDA level (r = 0.828, P < 0.05) in rotenone group. In the rotenone plus erdosteine group, there was a negative correlation between XO activity and NO level in liver tissue (r = -0.833, P < 0.05). In the light of these findings, erdosteine may be a protective agent for rotenone-induced liver oxidative injury in rats. |
