IntroductionResearch studies carried out for decades have not solved the problem of the effect of electromagnetic radiation of various frequency and strength on the human organism. Due to this fact, we decided to investigate the changes taking place in human blood platelets under the effect of electromagnetic radiation (EMR) emitted by LCD monitors.Material and methodsThe changes of selected parameters of oxygen metabolism were measured, i.e. reactive oxygen species concentration, enzymatic activity of antioxidant defence proteins – superoxide dismutase (SOD-1) and catalase (CAT) – and malondialdehyde concentration (MDA). A suspension of human blood platelets was exposed to electromagnetic radiation of 1 kHz frequency and 150 V/m and 220 V/m intensity for 30 and 60 min. The level of changes of the selected parameters of oxidative stress was determined after the exposure and compared to the control samples (not exposed).ResultsThe measurements revealed an increase of the concentration of reactive oxygen species. The largest increase of ROS concentration vs. the control sample was observed after exposure to EMF of 220 V/m intensity for 60 min (from x = 54.64 to x = 72.92). The measurement of MDA concentration demonstrated a statistically significant increase after 30-min exposure to an EMF of 220 V/m intensity in relation to the initial values (from x = 3.18 to x = 4.41). The enzymatic activity of SOD-1 decreased after exposure (the most prominent change was observed after 60-min and 220 V/m intensity from x = 3556.41 to x = 1084.83). The most significant change in activity of catalase was observed after 60 min and 220 v/m exposure (from x = 6.28 to x = 4.15).ConclusionsThe findings indicate that exposure to electromagnetic radiation of 1 kHz frequency and 150 V/m and 220 V/m intensity may cause adverse effects within blood platelets’ oxygen metabolism and thus may lead to physiological dysfunction of the organism.

Background. Electromagnetic radiation emitted by a variety of devices, e.g. cell phones, computers and microwaves, interacts with the human body in many ways. Research studies carried out in the last few decades have not yet resolved the issue of the effect of this factor on the human body and many questions are left without an unequivocal answer. Various biological and health-related effects have not been fully recognized. Thus further studies in this area are justified. Objectives. A comparison of changes within catalase enzymatic activity and malondialdehyde concentration arising under the influence of the electromagnetic radiation emitted by car electronics, equipment used in physiotherapy and LCD monitors. Material and Methods. The suspension of human blood platelets at a concentration of 1 × 10 9 /0.001 dm

Objectives: The aim of the study was to assess the influence that the shape of low frequency magnetic field may have on catalase and superoxide dismutase activity, malondialdehyde concentration and free radicals generation in human blood platelets. Materials and methods: The suspension of human blood platelets was exposed for 15 min to 50 Hz magnetic field of different shape, and flux density of 10 mT. Results: The determinations of free radicals, malondialdehyde and catalase showed increased values compared with the initial level, regardless of the shape of the magnetic field applied. In contrast, superoxide dismutase activity was lower than at the onset of the experiment. Conclusions: The findings indicate that the oxidative stress resulting from exposure to 50 Hz magnetic field of 10 mT induction may produce a number of adverse effects within the cell and thus may lead to systemic disturbances in the human body.

Frequent consumption of large amounts of alcohol usually does not correspond to regular physical activity. However, regular physical activity can lead to an improved well-being and greater satisfaction with life. The aim of the study was to determine the level of physical activity in the group of patients diagnosed with alcohol dependence syndrome and examine the correlation between these variables. The study was conducted among a selected group of individuals of both sexes, aged 22-65 and undergoing treatment. Our study indicated an absence of a correlation between gender and the level of physical activity among people addicted to alcohol. Moreover, no statistically significant relationship was found between alcohol dependence and physical activity undertaken in the researched group. Keywords: alcoholism, movement activity.Częste spożywanie dużych ilości alkoholu zazwyczaj nie koresponduje z regularnym podejmowaniem aktywności fizycznej. Jednak regularna aktywność fizyczna może prowadzić do poprawy samopoczucia i większej satysfakcji z życia. Celem badania było określenie poziomu aktywności ruchowej w grupie pacjentów ze zdiagnozowanym zespołem uzależnienia od alkoholu oraz sprawdzenie korelacji między tymi zmiennymi. Badanie przeprowadzono wśród wybranej grupy leczących się osób obojga płci, w wieku 22-65 lat. W badaniu własnym nie odnotowano zależności między płcią a poziomem aktywności fizycznej osób uzależnionych od alkoholu. Nie wykazano również zależności istotnej statystycznie pomiędzy istnieniem uzależnienia od alkoholu a podejmowaną aktywnością fizyczną w badanej grupie. Słowa kluczowe: alkoholizm, aktywność ruchowa.Частое употребление большого количества алкоголя обычно не коррелирует положительно с регулярной физической активностью. Однако регулярная физическая активность может привести к улучшению самочувствия и повышению удовлетворенности жизнью. Целью исследования было определение уровня двигательной активности в группе пациентов с диагностированным синдромом алкогольной зависимости, а также проверка корреляции между этими двумя переменными. Исследование проводилось среди избранной группы проходящих лечение пациентов обоих полов в возрасте 22-65 лет. В собственном исследовании не было обнаружено зависимости между полом и уровнем физической активности зависимых от алкоголя людей. Не была также выявлена статистически значимая зависимость между наличием алкогольной зависимости с предпринимаемой физической активностью в группе испытуемых.
