[Change settings for visual analyzer of child users of mobile communication: longitudinal study].

The paper represents theresults of longitudinal monitoring of the changes in the parameters of simple visual-motor reaction, the visual acuity and the rate of the visual discrimination in the child users of mobile communication, which indicate the multivariability of the possible effects of radiation from mobile phones on the auditory system of children.

[On one term (translation of SAR) in the dosimetry of radiofrequency electromagnetic fields].

Uncertainties in the use of some terms in the dosimetry of radiofrequency electromagnetic fields are discussed. We have come to the conclusion that the term conventionally applied in the Russian literature to describe the absorbed energy is an incorrect translation of the international term "Specific Absorption Rate" (SAR). The main error in the Russian term is that the energy rather than the rate is absorbed. More precise Russian definition for this term is suggested by analogy with the dosimetry of ionizing radiation. In this case, the dimension of this parameter remains without any change.

[Changes in the parameters of the simple auditory-motor response in children users of mobile communication: longitudinal study].

The study presents the findings of longitudinal observations of the changes in the parameters of simple auditory-motor response in children-users of mobile communication. The obtained results indicate the multivariability of possible effects of radiation from mobile phones on the auditory system of children.

[Ionizing and non-ionizing radiation (comparative risk estimations)].

The population has widely used mobile communication for already more than 15 years. It is important to note that the use of mobile communication has sharply changed the conditions of daily exposure of the population to EME We expose our brain daily for the first time in the entire civilization. The mobile phone is an open and uncontrollable source of electromagnetic radiation. The comparative risk estimation for the population of ionizing and non-ionizing radiation was carried out taking into account the real conditions of influence. Comparison of risks for the population of ionizing and non-ionizing radiation leads us to a conclusion that EMF RF exposure in conditions of wide use of mobile communication is potentially more harmful than ionizing radiation influence.

[Mobile communication and health of population: estimation of danger, social and ethical problems].

Population lives under new electromagnetic conditions: constant round-the-clock compulsory chronic exposure of all groups of population to modulated wide spectrum of EMF RF during the work of base stations of mobile communication; daily and lifelong (from childhood) exposure of the brain to EMF RF of the mobile phone. Effects of exposure to EMF RF of low levels are presented. Results of research into chronic EMF RF exposure are absent. International recommendations and domestic guidelines do not take into account the changing conditions of EMF RF influence on the population: the brain has become a critical body, and children have been included in the risk group. Population actively continues to use mobile communication. In this situation estimation of the risks from mobile communication has become a social and ethical problem.

[New data for proving the presence of significant effects of electromagnetic exposure (to autoimmune changes in rats)].

The study using statistical analysis methods and the generalized logarithmic parameter describing the change in the condition of biological systems represents additional substantiations and proofs of the presence of the expressed amplification of the immune reaction in experimental animals after a long exposure to EMF RF non-thermal intensity with a power density of 500 microW/cm2. A substantial growth of titers of antibodies to the brain tissue on the 14th day and to a number of other antigens on the 7th and 14th days after irradiation is shown with high reliability of 99.9%. It is shown that EMF RF exposure to non-thermal intensity within 30 day causes transition of an organism to an active adaptation described by an amplified strengthening of intensity of the regulation systems of the organism.

[Psychophysiological indicators for children using mobile phones. Communication 1. Current state of the problem].

An overview of the epidemiological and experimental evidence for exposure of humans and animals to electromagnetic radiation produced by mobile phones is provided. The effects of mobile phone radiation on the child's body are considered in detail. It has been shown that the children's organism is more sensitive to this kind of exposure than the adult one.

[Psychophysiological indicators for children using mobile phones. Communication 2. Results of four-year monitoring].

This study submits the results of a four-year monitoring of a complex diagnostics of the psychophysiological indicators for 196 children aged 7 to 12 years old: 147 of them are child users of mobile communication (test group) and 49 are in the control group. We have identified the following major trends of the psychophysiological indicators for child users of mobile communication: an increased number of phonemic perception disorders, abatement of efficiency, reduced indicators for the arbitrary and semantic memory, an increased fatigue. A steady decline of the parameters from high values to bottom standards has been found.

[The probability of developing brain tumours among users of cellular telephones (scientific information to the decision of the International Agency for Research on Cancer (IARC) announced on May 31, 2011)].

The WHO's International Agency for Research on Cancer (IARC) has made May 31 2011 PRESS RELEASE No 208 which classifies radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B). The decision is based on an increased risk of glioma, i.e., a malignant type of brain cancer associated with the wireless phone use. This paper reports the analysis of the long-term research on the issue in question that had been carried out in many countries around the world before the decision was made.

[Indralin--a novel effective radioprotector during irradiation by high-energy protons].

Experiments with 120 mongrel dogs were aimed at the assessment of radio protective strength of indralin and local shielding of the pelvic marrow from 2.5 Gy, and also their concurrent use for the dogs irradiated by protons (240 MeV) at absolutely lethal and over-lethal 4 Gy and 5 Gy. Clinical observations, hematological investigations and ECG analysis of survived animals were conducted 4.5 years post the irradiation. Dogs that remained healthy following 3.5 to 4.5 years since the irradiation were sacrificed for pathomorphological investigations. The radioprotective effect of local shielding against 4 Gy was weak while this effect of intramuscular indralin (10, 20, 40 mg/kg of body) was significant reaching 50 to 67.7%. The concurrent use of two methods had, apparently, potentiated the 100% radioprotection of the animals irradiated by overlethal 5 Gy. Blood investigations of the survived dogs every 2-4 months evidenced that complete recovery of the total leukocyte count had taken 9 to 13 months. Also, dogs' pregnancy in 9-10 months since the beginning of irradiation pointed to maintenance of fertility and the ability to parturiate 2 or 3 times yielding 5-6 live cubs. Necropsy of the dogs did not reveal gross macroscopic structural changes of visceral organs or tissues. Seven out of 27 sacrificed dogs had benign tumors infrequent in intact dogs at this age.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 1. Mobile communications and changes in electromagnetic conditions for the population. Needs for additional substantiation of the existing hygienic standards].

Mobile communications provides a new source of electromagnetic exposure for almost the whole population of the Russian Federation. For the first time in the history of civilization the brain of mobile phone users was exposed to localized radiofrequency (RF) electromagnetic fields (EMF). Population exposure from the base stations is also considered to be specific. However, existing standards for limiting the exposure do not account for this special EMF source and may not ensure the absence of health effects. There was a need for reliable information that would extend databases used for development of new standards. As recommended by the World Health Organization an additional experiment was performed under the supervision of foreign experts, which showed changes in autoimmune status in rats after long-term low-level RF EMF exposure with an incident power density of 500 microW/cm2.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 2. General scheme and conditions of the experiment. Development of RF exposure conditions complying with experimental tasks. Animal's status during the long-term exposure].

This paper describes the conditions for handling and exposure of experimental animals (Wistar rats) and methods used in the study of immunological effects of long-term low-level (500 microW/cm2) exposure to radiofrequency (2450 MHz) electromagnetic fields, performed under auspices of the World Health Organization.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 4. Manifestation of oxidative intracellular stress-reaction after long-term non-thermal EMF exposure of rats].

This paper presents the results of the study of the effects of long-term low-level exposure of rats to microwaves. Rats were exposed in far field to 2450 MHz continuous wave fields providing an incident power density at the cages of 500 microW/cm2 for 7 hours daily for a total of 30 days resulting in a whole-body SAR of 0.16 +/- 0.04 W/kg. Three groups ("EMF-exposure", "sham-exposure" and cage-control) were formed, each consisting of 16 rats. Circulating antibodies (IgA, IgG and IgM) directed against 16 chemical substances were evaluated in coded serum from each group of rats by enzyme multiplied analysis (ELISA test). An increased amount of compounds resulting from interaction of amino acids with nitric oxide (NO) or its derivatives (NO2-Tyrosine, NO-Arginine, NO-Cysteine + NO-Bovine Serum Albumin, NJ-Methionine + NO-Asparagine + No-Histidine, NO-BTrypnohan + NJ-Tyrosin), fatty acids with small chains, hydroxylated fatty acids, palmitic/myristic/oleic acid, AZE (product of oxidation of fatty acids) was found in blood serum from EMF-exposed rats. As a rule, antibodies to conjugated antigens were seen for IgM, rarely seen for IgG and were completely absent for IgA. The levels of antibodies were higher on day 7 after the exposure compared to those on day 14 after the exposure.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 5. Impact of the blood serum from rats exposed to low-level electromagnetic fields on pregnancy, foetus and offspring development of intact female rats].

This study evaluated possible adverse effects of injection of blood serum from rats exposed to microwaves at a power density of 500 microW/cm2 on pregnancy and foetal and offspring development in intact female rats. The study was performed with 59 pregnant Wistar rats. In utero mortality, embryo and foetal body weights and placenta weight were used for the evaluation of embryo and foetal development. Generally accepted integral and specific parameters were used for the evaluation of postnatal development of offspring during the first 30 days of life. It was shown that intra peritoneal injection of blood serum from IMF exposed rats (chronic 30-day RF exposure at 500 microW/cm2) to intact rats on the 10th day of pregnancy resulted in adverse effects on foetal and offspring development. Total mortality (in utero + postnatal) as well as delay in offspring development was higher in this group.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 3. The effect of the long-term non-thermal RF EMF exposure on complement-fixation antibodies against homologenous tissue].

This paper presents the results of the study of immunological effects of long-term low-level exposure of rats to microwaves. Rats were exposed in the far field to 2450 MHz continuous wave fields providing an incident power density at the cages of 500 microW/cm2 for 7 hours daily for a total of 30 days, resulting in a whole-body SAR of 0.16 +/- 0.04 W/kg. Effects of the exposure on immunological parameters in the brain and liver of rats were studied using Complement Fixation Test at low temperature (4 degrees C). Three groups ("EMF-exposure", "sham-exposure" and cage-control) were formed, each consisting of 16 rats. On the 14th day after the 30-day exposure, titers of antibodies against brain tissue were 0.69 +/- 0.08 in the cage-control group, 0.89 +/- 0.05 in the sham-exposed group and 1.19 +/- 0.07 in the EMF-exposed group. The appearance of antibodies against liver antigens was less. The increase in titres of antibodies against brain homogenates in the sham-exposed and EMF-exposed groups could be explained by the stress-reaction of the animals and autoimmunization of organism.

[Non-thermal electromagnetic fields and estimation of the convulsive syndrome probable development].

There are cases of development of a convulsive syndrome at influence of electromagnetic field (EMF) in physiotherapy practice, and in conditions of a professional work. There is a point of view that EMF can render medical effect at treatment of a epilepsy syndrome. Some publications specify on develop of epilepsy convulsions in experiment at EMF of various frequencies exposure. Four conditions which can promote development of convulsions at EMF exposure are considered.

[Dependence of the non-thermal radiofrequency electromagnetic field bioeffects on the typological features of electroencephalogram in humans].

In researches with participation of volunteers bioeffects of short-term non-thermal radiofrequency electromagnetic field (RF EMF) exposure were studied. The basic form of brain's reaction was the amplification of energy in a-range in electroencephalogram (EEG) spectra. Dependence of these changes, not only due to the changes of the exposure parameters, but also due to personal EEG typological features was shown. Moderate degree of the alpha frequencies domination in the background promoted development of reaction of a brain to the RF EMF exposure. To a lesser degree it was shown at hyperactivity of this range and, practically, was absent in the conditions of theta- or beta2-range domination in the EEG background with the open and closed eyes. The combination of RF EMF exposure and monotonous activity has authentically strengthened result, keeping the basic form of reaction (energy amplification in the alpha range of EEG spectrum) and dependence on EEG typological features.
