Tobacco is one of the main factors responsible for the development of human tumors, cardiovascular diseases and non-malignant respiratory diseases. Tobacco products are harmful to health and they contain nicotine, which is highly addictive. Many studies in humans and in animal models have shown that nicotine is addictive psychoactive drug, which triggers a cascade of neurobiological events in the brain reward centers leading to the intensity of behavior what aims to enhanced use of tobacco. In Poland the number of smokers is estimated at about 9.5 million people. Among active smokers is a significant number of medical students. 480 people have joined the study (253 women and 227 men): 416 student of Collegium Medicum in Bydgoszcz of Nicolaus Copernicus University in Torun (CM UMK), 59 students of biomedical engineering at the University of Technology and Life Sciences in Bydgoszcz and 5 employees of CM UMK. 13% of all respondents admitted to smoking cigarettes. Respondents students and university staff mainly responded affirmatively to the question about psychoactive addiction by smoking-Performed questionnaire also revealed a high awareness about the use of nicotine during smoking cessation. Most people had their first contact with tobacco smoke in the early years of life, meeting with tobacco smoke in the home and in school. A much smaller percentage of the students met for the first time to tobacco smoke in the later stages of education: high school and college. Even fewer respondents had their first encounter with tobacco smoke in the workplace. In summary, we can conclude that students and workers CM UMK show considerable awareness of the dangers of smoking and the addictive properties of tobacco smoke.

Smoking cigarettes and alcohol addiction are serious problems in health hazard and life of society. Tobacco smoke leads to many kinds of cancer formation and scientific research indicates, that heart-vascular disease and lung cancer are the most common diseases caused by tobacco smoke. While talking about ethanol, it is responsible for liver, pancreas, mucous membrane damage and leads to central and circular nervous disorder. Scientific research indicates, that many smokers drink alcohol and vice versa. Unfortunately in that case the risk of many diseases increases. Both of these stimulants leads to enlarged production of reactive oxygen species, which is connected with unbalance between pro and antioxidant processes in human organism. Free radicals in normal conditions plays positive role but with tobacco smoke and alcohol connection may lead to serious changes in human organism. They damage organs, it comes to protein structure, nucleic acid and fat violation, which in consequence leads to immunity decrease and many pathological changes. Reactive oxygen species also plays role in pathogenesis of many diseases: diabetes mellitus, atherosclerosis and Down syndrome. ROS may also increase the risk of pancreas, lung, larynx and urinary bladder cancer formation. Human organism defends oneself from harmful influence of reactive oxygen species owing to enzymatic and non-enzymatic systems presence-Non-enzymatic antioxidants: glutathione, carotene, bilirubin, tocopherol, uric acid and ions metals temporary complex belong to non-enzymatic systems. To enzymatic ones belong: catalase, superoxide dismutase, glutathione reductase and glutathione peroxidase. The aim of the study was tobacco smoke and ethyl alcohol influence evaluation in rats addicted to these substances on activity of chosen enzymes responsible for organism defense against toxic compounds action. To this study 63 white, Wistar tribe rats at the age of 3,5 months were used – males addicted to ethyl alcohol. They were divided into 3 groups, each consist of 21 rats. Animals of Group I were exposed on harmful tobacco smoke influence. Group II constitute animals, which were given by stomach probe 10% alcohol dilution once at a dose of 2 g/kg weight. The next Group – III, in which animals at first were exposed on tobacco smoke influence. When exposition was over, animals were given by stomach probe 10% alcohol dilution once at a dose of 2 g/kg weight. Depending on the type of marker and studied organ, changes in the levels of selected enzymes, responsible for defending organism against reactive forms of oxygen has been shown. Both tobacco smoke and ethyl alcohol resulted in a change of glutathione levels in the serum and tissues of animals. Tobacco smoke has the biggest influence on protein nitrozylation in the brain and ethyl alcohol had influence on glutathione level in serum, kidney, brain and superoxide dismutase activity in the brain. Application of many oxidative stress markers allows for evaluation of its differential influence on various organs.
