Efficiency of endothelial dysfunctioncorrection in children residents of radioactively contaminated areas using the method of intermittent normobaric hypoxi therapy.

Unlabelled: Objective is to evaluate the effectiveness of intermittent normobaric hypoxi therapy as the means that can posi tively influence on the different links in the pathogenesis of endothelial dysfunction in children residents of radioactively contaminated areas.

Materials And Methods: Disorders of personal and emotional sphere, symptoms of asthenic vegetative and neurot ic character, the signs of the cardiovascular and respiratory systems, abdominal and dyspeptic syndromes are attrib uted to the clinical signs of endothelial dysfunction. There were determined the biochemical parameters of the con tent of stable metabolites of NO, L arginine, lipid peroxidation, antioxidant enzymes in the blood serum; the indices of cellular and humoral immunity; the instrumental indices of vascular endothelium dependent reaction to occlu sion test, ventilating ability of the lungs, the bioelectric activity of the myocardium.

[SEASONAL DIFFERENCES IN THE EFFECT OF MELATONIN ON THE MORPHO-FUNCTIONAL STATE OF THE THYROID GLAND SPONTANEOUSLY HYPERTENSIVE RATS].

We studied the effect of exogenous melatonin on the indicators of thyroid gland condition of the young spontaneously hypertensive rats in spring and autumn. These data suggested that after 28-day of melatonin administration (5 mg/kg) in different seasons of the year there were divergent effects on the state of the thyroid gland. So, melatonin increased synthetic activity of the gland in the spring.

[INFLUENCE OF INTERMITTENT NORMOBARIC HYPOXIA ON CARDIOVASCULAR SYSTEM AND HEMODYNAMIC PARAMETERS OF CHILDREN LIVED AT RADIATION CONTAMINATED TERRITORIES.].

The effect of intermittent normobaric hypoxia (INH) of sanogenic level on the state of the cardiovascular system in 120 children aged from 12 to 17 years was studied. Children were divided into 3 groups. The 1st control group consisted of 20 persons (practically healthy ones), the 2nd group, a group of comparison, included 50 persons, and there were 50 persons in the 3rd group - a main group.

Red blood cell transfusions--are we narrowing the evidence-practice gap? An observational study in 5 Israeli intensive care units.

Purpose: The aim of the study was to document transfusion practices in a cross section of general intensive care units (ICUs) in Israel and to determine whether current guidelines are being applied.

Materials And Methods: This prospective study was performed in 5 general ICUs in Israel over a 3-month period. Red cell transfusion data collected on consecutive patients included the trigger, units transfused per transfusion event, and indications, categorized either to treat a specified condition for which transfusions may be beneficial (acute hemorrhage, acute myocardial ischemia, or severe sepsis) or to treat a low hemoglobin concentration.

Particle acceleration by stimulated emission of radiation: theory and experiment.

The interaction of electromagnetic radiation with free electrons in the presence of an active medium has some appealing outcomes. Among them is particle acceleration by stimulated emission of radiation (PASER). In its framework, energy stored in an active medium (microscopic cavities) is transferred directly to an e -beam passing through.
