Opis:: Free radicals in Cladosporium cladosporioides cultured with amphotericin B were spectroscopically studied. The effect of drug concentrations on free radicals in the fungal melanin biopolymer was examined. It was pointed out that the concentrations of free radicals in the complexes of Cladosporium cladosporioides mycelium with amphotericin B depend on the drug concentrations. Eumelanin dominates in the fungal studied samples. The slow spin-lattice relaxation processes exist in the tested samples. Free radicals take a part in the formation of Cladosporium cladosporioides mycelium complexes with amphotericin B.

Opis:: Paramagnetic centers in melanin existing in pigmented soil fungi Cladosporium cladosporioides cultured at acidic (4, 5, 6), neutral (7), and alkaline (8) pH were studied by EPR method. o-semiquinone free radicals (g: 2.0032-2.0040) concentration in melanin biopolymer increased for pH from 4 to 6, decreased at pH 7, and reached the maximum value at pH 8. It may be expected that melanin free radicals reactions with small molecules (metal ions, drugs) are the most effective at pH between 6 and 8. Slow spin-lattice relaxation processes exist in the all studied melanin samples.

Opis:: Introduction. Adequate levels of physical activity throughout an individual’s life ensure an optimal state of health. Only 30% of adolescents and 10% of adults perform sufficient physical activity to facilitate proper physical, psychological/mental and emotional development. Objective. Determining physical activity behaviour in children and adolescents through surveying the opinions of school pupils and parents, in order to lend support for optimised educational programmes designed to promote healthy lifestyle behaviour, as well as establishing consistent answers. Materials and Methods. A randomised survey was conducted on two groups of n=1100 pupil subjects, each attending elementary or secondary school, with the former in Classes 5 and 6, whereas the latter were aged between 16–19 years old; in both instances parents were also included in the survey. All subjects came from the Kalisz District in western-central Poland, and were divided into those living in the city of Kalisz and those in the surrounding rural areas. Results. It was found that 87%, 96% and 89% of elementary, middle and secondary school pupils, respectively, participated in Physical Education (PE) lessons. The numbers of pupils who daily, or almost daily, spent time on a computer, were 52%, 60% and 70%, respectively, for elementary, middle and secondary schools, and likewise 70%, 62% and 48% for watching TV. Conclusions; It is vital that education programmes with a focus on a healthy lifestyle are introduced and targeted at teenagers in order to promote physical activity during the crucial time of the body’s development. The period of maturing into adulthood is particularly crucial for acquiring the right knowledge, convictions, skills and attitudes that help shape a pro-healthy lifestyle in later years.

Opis:: Introduction. An adequate mode of nutrition is among the most important environmental factors affecting the development of Man and maintenance of a good health status. An improper selection of nutrients and irregular consumption of meals may lead to overweight and obesity. Objective. The characteristics of health behaviours of the examined population of schoolchildren, with consideration of nutrition and body weight disorders. A comparison of the opinions of schoolchildren and their parents concerning health behaviours. Development of guidelines for educational programmes carried out in the place of residence of the population of schoolchildren and their parents. Materials and method. The survey covered a randomised group of schoolchildren attending elementary and secondary schools in the Kalisz Province and province of the city of Kalisz. The study was conducted in May and June 2009, in a randomly selected representative group of 1,100 boys and girls from classes V and VI of elementary schools, and 1,100 secondary school adolescents aged 16–19 and their parents. The studies of schoolchildren attending elementary and secondary schools were compared with the all-Polish studies of junior high school adolescents in the school year 2006–2007. Results. The respondents most often consumed 3–4 meals; however, as many as 26% of junior high school adolescents and 27% of secondary school adolescents admitted that they consume only one meal daily. The schoolchildren show inadequate nutritional habits concerning an insufficient consumption of fruits, vegetables and fish, in favour of high calorific meals and sweet snacks and drinks. Parents improperly assess the body weight of their children and perceive them as slimmer, which is not confirmed by the BMI value for age and gender. Conclusions. Systematic monitoring and analysis of changes in the health behaviours of adolescents should be a basis for planning health education and promotion programmes. Educational programmes concerning various aspects of health should be implemented in an organized and complementary way, directed not only at schools, but also at entire families and local communities. Knowledge, beliefs, skills and attitudes towards health acquired during the period of adolescence decide about life style in adulthood.

Opis:: Objectives To determine the age and the most common circumstances for smoking initiation along with smoking rates and to evaluate smoking trends for secondary and high school students in Poland during 2009 and 2011. Material and Methods In 2009, a pilot study was conducted in districts of Poland on high school students and their parents. For statistical analysis, correctly completed questionnaires from 999 students and 667 parents were qualified for use. After the pilot study, a nationwide study of secondary school students and their parents was also conducted in 2009. For statistical analysis, correctly completed questionnaires were used from 9360 students and 6951 from their parents. The research tool was a questionnaire developed by the Chief Sanitary Inspectorate. These studies were then compared to the nationwide research study from 2011. Questionnaires were obtained from a survey of 3548 students from secondary schools and 4423 of those from high schools. Results Smoking initiation usually begins at ages 12–15 years. Rates of secondary school student smoking at least once in their lifetime were about the same level in the surveyed years (2009 – 9%, 2011 – 11%), whereas rates of high school student smoking increased (2009 – 15%, 2011 – 24%). Moreover, 34% of secondary school student smoked less than once a week, whereas in 2009, only 8% of students had done so. For high school students, a 1/2 smoked every day; similar to 2009. Students usually smoked in parks, on streets or any other open space areas. Conclusions From analyzing the smoking trends over the survey period it can be concluded that the problem of smoking increases with respondent age. Int J Occup Med Environ Health 2017;30(5):763–773
