Evaluation of the effectiveness of laser photoselective vaporization of the prostate in the treatment of patients with benign prostatic hyperplasia.

Introduction: The prolongation of the life of men results in the growing number of people suffering from benign prostatic hyperplasia (BPH). In 2010, BPH concerned more than 200 million men in the whole world, which at that time made up 6% of the population of men at large. Currently, the population of men in the world amounts about three billion six hundred million.

Smoking-related behaviours of pregnant women depending on their place of residence.

Oxidative stress in colonic adenocarcinoma: An impact on the body's antioxidative status and oxidative protein damage.

Background: Thus far, the pathogenesis of these intestinal tumors has not been fully explained. However, the analysis of risk factors and research regarding their formation that have continued for 3 decades have allowed us to demonstrate a significant role of oxidative stress in the processes leading to the development of cancer in the large intestine as well as in some other organs.

Objectives: The aim of the study was to examine the level of anti-oxidative status and the degree of oxidative protein damage in patients with varying severity of colonic adenocarcinoma (CAC) in relation to healthy individuals.

Impact of electromagnetic radiation emitted by monitors on changes in the cellular membrane structure and protective antioxidant effect of vitamin A - In vitro study.

Objectives: The increasing number of devices emitting electromagnetic radiation (EMR) in people's everyday life attracted the attention of researchers because of possible adverse effects of this factor on living organisms. One of the EMR effect may be peroxidation of lipid membranes formed as a result of free radical process. The article presents the results of in vitro studies aimed at identifying changes in malondialdehyde (MDA) concentration - a marker of lipid peroxidation and antioxidant role of vitamin A during the exposure of blood platelets to electromagnetic radiation generated by liquid-crystal-display (LCD) monitors.

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.

[Effect of electromagnetic field produced by mobile phones on the activity of superoxide dismutase (SOD-1)--in vitro researches].

The aim of the paper was to estimate in vitro the effect of electromagnetic field produced by mobile phones on the activity of superoxide dismutase (SOD-1) in human blood platelets. Suspension of blood platelets exposed to the electromagnetic field of 900 MHz frequency for 1, 3, 5, 7 minutes. Our studies demonstrated that microwaves produced by mobiles significally depleted the activity of SOD-1 after 1, 5, 7 min.

[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.

[Epidemiology of parasitic diseases in military personnel treated in the United Nations Interim Force hospital in Lebanon, from 1993 to 2000].

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

Tamsulosin: efficacy and safety in patients with neurogenic lower urinary tract dysfunction due to suprasacral spinal cord injury.

Purpose: We evaluated the efficacy and safety of tamsulosin in patients with neurogenic lower urinary tract dysfunction secondary to suprasacral spinal cord lesions in a 4-week randomized controlled trial (RCT) followed by a 1-year, open label, long-term study.

Materials And Methods: A total of 263 patients were randomized to 4-week double-blind therapy with placebo, or 0.4 or 0.

[Effect of electromagnetic field produced by mobile phones on the activity of superoxide dismutase (SOD-1) and the level of malonyldialdehyde (MDA)--in vitro study].

The aim of the study was to assess in vitro the effect of electromagnetic field produced by mobile phones on the activity of superoxide dismutase (SOD-1) and the level of malonyldialdehyde (MDA) in human blood platelets. The suspension of blood platelets was exposed to the electromagnetic field with the frequency of 900 MHz for 1, 3, 5, and 7 min. Our studies demonstrated that microwaves produced by mobile phones significantly depleted SOD-1 activity after 1, 5, and 7 min of exposure and increased after 3 min in comparison with the control test.

Generation of reactive oxygen species in blood platelets.

The generation of superoxide anion radicals (O2*-) and the other reactive oxygen species (ROS) was estimated by means of cytochrome c reduction and chemiluminescence, as well in resting blood platelets and in platelets stimulated by thrombin in the presence or absence of some inhibitors of pathways involved in platelet activation. We used allopurinol (xanthine oxidase inhibitor), wortmannin (PI 3-kinase inhibitor) and staurosporine (protein kinase C inhibitor). To determine the involvement of the glutathione in ROS generation, we used L-buthionine sulfoximine (BSO) which blocks GSH synthesis.
