The effect of electromagnetic radiation emitted by display screens on cell oxygen metabolism - in vitro studies.

Introduction: Research 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 Methods: The changes of selected parameters of oxygen metabolism were measured, i.

The impact of electromagnetic radiation of different parameters on platelet oxygen metabolism - in vitro studies.

Background: Electromagnetic radiation emitted by a variety of devices, e.g. cell phones, computers and microwaves, interacts with the human body in many ways.

The effect of 50 hz magnetic field of different shape on oxygen metabolism in blood platelets: in vitro studies.

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.

[Influence of electromagnetic field on chosen parameters of thrombocytes' oxygen metabolism--in vitro research].

Unlabelled: Being a natural environmental factor, an electromagnetic field exists from the beginning of the life on Earth and it has an influence on maintenance of life processes. Natural electromagnetic fields affect day and year rhythms of plants, animals and humans. As a result of an electromagnetic field's activity, there occurs a disorder of blood platelets' function, which may, in consequence, lead to acute and chronic conditions dangerous to health and life.

[Infectious diseases among military personnel in the catchment area of the United Nations Interim Force in Lebanon hospital, from 1993 to 2000].

In the study the incidence of infectious diseases among military personnel of the United Nations Interim Force in Lebanon and local civilian population is examined. Additionally, the authors investigate the potential risk factors, including environmental conditions, influencing the incidence of infectious diseases. Epidemiological analysis was conducted based on the medical records of patients treated in the Internal and Surgical Ward of the UNIFIL Hospital from 1993 to 2000.
