The aim of the study was to determine the effect of adding a mixture of anti-stress herbs to drinking water on stress hormone levels and the heterophil to lymphocyte ratio in the blood of intensively reared broiler chickens of three genetic lines. The experiment was performed with ‘Ross 308’, ‘Cobb 500’ and ‘Hubbard Flex’ broiler chickens, which were divided into three experimental groups. Birds were maintained on litter for 42 days at a stocking density less than 33 kg/m2. All the groups were provided with the same environmental and feeding conditions. In each group from 21 to 35 days of rearing, water drinkers were supplemented for 5 h/day (08:00–13:00 hours) with an alcoholic extract from mixed herbs (30% chamomile, 10% oregano, 10% yarrow, 10% knotgrass, 10% valerian, 20% inflorescence of large-leaved lime) at 2 ml/l water. At 21, 28, 35 and 42 days of rearing, blood was collected from 10 birds per group to determine corticosterone, noradrenaline and adrenaline levels. The heterophil to lymphocyte ratio (H:L) was also calculated. On day 42 of the study, 500 broiler chickens were characterised by the lowest noradrenaline concentration and a lower H:L ratio compared to ‘Ross 308’ and ‘Hubbard Flex’ (p ≤ 0.05) and ‘Ross 308’ chickens (p ≤ 0.01), respectively. It was concluded from the study that the herb extract had the most favourable effect on relieving the body’s physiological response to stress, and thus on improving welfare in ‘Cobb 500’ compared to ‘Ross 308’ and ‘Hubbard Flex’ broilers. It can therefore be considered that active substances in herbs have varying effects on the body of broiler chickens of different origin.

Objectives This study has aimed at investigating the impact of the Special Aviation Gymnastics Instruments (SAGI) training scheme on the blood serum cortisol, testosterone, insulin, and plasma adrenaline, noradrenaline, and dopamine in comparison with a control group. Material and Methods Fifty-five cadets, aged 20 years old, participated in the study. Cadets were divided into 2 groups: A (N = 41) – the SAGI-trained, and B (N = 14) – the control group. In both groups, blood was the examined material, sampled twice: before the training session (BT) and after the training session (AT), at the beginning (training session I), during (training session II), and after completion of the SAGI training session (training session III). Commercially available kits were used for assaying serum cortisol, testosterone, and insulin as well as plasma adrenaline, noradrenaline, and dopamine. Cadets’ physical fitness was assessed by means of Aero-Synthetic Efficiency Tests. Results In group A, a significant decrease in serum cortisol (training session III) and insulin in three training sessions AT in comparison with the values BT was seen. A statistically significant increase in testosterone and catecholamines was noted in all 3 training sessions AT in comparison with the values BT. In group B, a statistically significant increase in cortisol (training session II), testosterone, and catecholamines was observed in all 3 training sessions AT vs. the values in training session BT. In group B, serum levels of all assayed hormones were higher in training session III than those in group A. Conclusions In the examined group, the SAGI training produced fewer hormonal changes dependent on the intensity and exercise type and physical efficiency improvement than in the control group.

The presented study dwells on the issue of game theory by Roger Caillois to be applied to the contemporary dimension of digital games. The actual attempt is to find out the extent to which the game principle categories apply to media products, i.e. digital games. The paradigms by authors engaged in cultural anthropology, philosophy, psychology, and sociology, besides others, served as key theoretical groundwork for the present paper. Nevertheless, the theories concluded within media study addressing the game and game principles in contemporary society have not been excluded either. In essence, the theoretical reflection introduces the basic terminology axis creating an apt platform for the game variants in use, to perform within the forms of new reality, i. e. virtual reality. The primary aim is to define elementary concepts like “game”, “game principles”, “media or virtual space”, “digital game”, and “game genres”. Secondary is then to explicate certain game principles designated by Roger Caillois present in the particular game. Material to be applied for this study ranks among the genre of action games. “Action game” particularly is a digital genre that belongs to frequent genre types as well as RPG games, strategy and others. Drawing from this fact, one of the actual digital games called Mafia III was chosen for empirical study. The main purpose of the paper is through logical analysis to illustrate the issue of games, and subsequently point out the cases of their occurrence in the media space. Theoretical postulates by Roger Caillois are by author assumed to be potentially applicable to the current media reality of digital games that come under action genres.

W artykule przedstawiono życiorys wybitnego polskiego fizjologa Napoleona Cybulskiego (1854 - 1919). Opisano następnie jego wkład w rozwój medycyny polskiej i światowej, wynalazki, a także dorobek piśmienniczy, zwłaszcza w zakresie fizjologii. Zaprezentowano także jego poglądy dotyczące roli i znaczenia nauki w życiu społecznym oraz stosunek do metodologicznych koncepcji uczonych niemieckich w dziedzinie nauk medycznych i przyrodoznawstwa, zwłaszcza mechanicyzmu R. Virchowa i witalizmu H. Driescha. Ponieważ Cybulski interesował się także problemami społecznymi i politycznymi, zwłaszcza stosunkiem państwa do finansowania badań naukowych oraz kwestią dopuszczenia kobiet do zawodów medycznych, podjęto się również analizy poglądów tego uczonego na ten temat. Ponadto opisano stosunek Cybulskiego do kwestii używania żywności wyprodukowanej przez uczonych w warunkach laboratoryjnych (mającej w przyszłości zastąpić w żywieniu w jego mniemaniu produkty naturalne), a także jego zdanie na temat mediumizmu i hipnozy.

The article presents the biography of the outstanding Polish physiologist Napoleon Cybulski (1854-1919). Then, his contribution to the development of Polish and world medicine, inventions, and his literary output, especially in the field of physiology, were described. His views on the role and importance of science in social life were also presented, as well as his attitude to the methodological concepts of German scientist in the field of medical sciences and natural sciences, especially R. Virchov’s mechanicism and H. Driesch’s vitalism. As Cybulski was also interested in social and political problems, in particular the attitude of the state to financing scientific research and the issue of admitting women to medical professions, an analysis of this scientist’s views on this subject was also undertaken. In addition, Cybulski’s attitude towards the use food produced by the scientists in laboratory conditions (which in his opinion is to replace natural products in nutrition in future) as well as his opinion on mediumism and hypnosis were discussed.

В статье представлена биография выдающегося польского физиолога Наполеона Цибульского (1854-1919). Затем были описаны его вклад в развитие польской и мировой медицины, изобретения и литературные произведения, особенно в области физиологии. Были представлены его взгляды на роль и значение науки в общественной жизни, а также его отношение к методологическим концепциям немецких ученых в области медицины и естествознания, особенно к механицизму Р. Вирхова и витализму Х. Дриша. Поскольку Цибульского также интересовали социальные и политические проблемы, в частности отношение государства к финансированию научных исследований и вопрос допуска женщин к медицинским профессиям, был также проведен анализ взглядов этого ученого на этот предмет. Кроме того, были описаны отношение Цибульского к проблеме использования продуктов питания, произведенных учеными в лабораторных условиях (предназначенных в будущем для замены натуральных продуктов в питании), а также его мнение о медиумизме и гипнозе.
