[Effect of combined exposure to ethanol and tobacco smoke on lipid peroxidation in rats].

Usually, alcohol addicted persons smokes cigarettes. In the study, the effect of combined exposure to alcohol and tobacco smoke in alcohol addicted rats on liver peroxidation was evaluated. Alcohol abuse and its presence in blood did not influence the cotinine level, what indicates the lack of the importance of this factor in nicotine metabolism. Similarly, enzymatic markers of liver damage (AspAT, AIAT, ALP) did not change, what showed lack of hepatotoxic effect studied compounds in applied model of alcohol addiction and tobacco smoke exposure. Combined exposure to alcohol and tobacco smoke increases the level of lipid peroxidation in brain, liver and lungs however decreases in serum. In kidneys the results are not unambiguous.
