title: The effect of antioxidants (N-acetylcysteine and melatonin) on hypoxia due to carbonmonoxide poisoning.
abstract: We aimed to determine the effect NAC (N-acetylcysteine) and melatonin on the histopathological and biochemical paramethers in the rats poisoned with CO (Carbon monoxide) experimentally. Winster albino female rats were placed in a plexiglass chamber and they were poisoned with CO. After the poisoning, rats were randomly divided into 3 groups. The group given only normal saline, was used as a control group (n = 9). The second group was given 30 mg/kg intraperitonally NAC (n = 10). And the third group was treated with 10 mg/kg of melatonin intramuscularly (n = 9). It is determined that some biochemical values affected by NAC but not by melatonin. CK, ALT, Lactate, MDA levels were significantly higher in NAC group than control and Melatonin group (p < 0.01 for all comparisons). Thiol level was lower in NAC group than control group and Melatonin group (p < 0.01 and p < 0.001, respectively). There were no statistical significant differences between the melatonin and control group. There were statistically significant difference between control, NAC and Melatonin groups according to brain and lung tissue damage. It is shown that both NAC and Melatonin are reducing the brain and lung tissue damage of CO poisoning but due to biochemical results worsened by NAC, Melatonin may recommend for CO poisoning (Tab. 3, Ref. 21).
