[The morphofunctional cellular evaluation of liver and kidney in rats in dynamics of 6-month consumption of water produced with the use of noncontact activation after electrochemical treatment].

There were investigated morphofunctional indices of liver and kidney in male outbred rats in the dynamics of the 6-months consumption of water after its noncontact activation. There were studied 4 experimental groups of animals consumed waters named as "Anolyte" and in dependence on the activation time, 3 types of catholyte water ("Catholyte--5", "Catholyte--25", "Catholyte--40"). Moscow tap water settled for a week served as control. "Anolyte" water was found to increase in the kidney the number of hypertrophied gromeruli only in 6 months, while the consumption of "Catholyte--25" water and especially, "Catholyte--40" in 1 and 6 months caused the damage of liver and kidney, and for the index of alteration of renal glomeruli after 6 months of water consumption there was revealed the dependence on the activation time of "Catalytes".

[Study of cytogenetic and cytotoxic effect of non-contact electrochemically-activated waters in the five organs of rats].

For the first time the multiorgan karyological analysis of five organs of rats was applied for the study of the cytogenetic and cytotoxic action of the four types of non-contact electrochemically activated water in the 30-days in vivo experiment. The effects of investigated waters were not detected in bone marrow polychromatic erythrocytes. "Anolyte" (ORP = -362 mV) did not have a negative effect on rats. "Catholyte-5" (ORP = +22 mV) and "Catholyte-25" (ORP = -60 mV) induced cytogenetic abnormalities in the bladder and fore stomach. The same catholytes and "Catholyte-40" (ORP = -10 mV) changed the proliferation indices: increased the mitotic index in the fore stomach epithelium and reduced the frequency of binucleated cells in the fore stomach, bladder and lungs. The increase in the rate of cells with cytogenetic abnormalities on the background of the promotion of mitotic activity can be considered as a manifestation of the negative effect, typical for catolytes, but the effect of each out of them has its own features.

[On the question of occurrence and the problem of hygiene rating of fungal air pollution of the environment of residential and public buildings].

Comprehensive sanitary examinations of fungal pollution of the environment of residential and public buildings were performed. There is established the occurrence of sensitization of the population associated with the fungal contamination of the wallings of buildings and presence of viable mold spores in the indoor air environment. Major factors determining the degree of fungal contamination of indoor environments: increasing humidity of indoor air due to leaks and bays, the area of enclosure structures and the temperature factor have been identified.

[Effect of multi-walled carbon nanotubes on the morphofunctional state of the small intestine cells of mice].

The experiment was conducted in male mice SBAchS57Vl/6 and Balb/c, which consumed water, obtained from the use of carbon nanotubes. in a free drinking regimen for 2 weeks (mice SBAchS57Vl/6) and 2 months (mice Balb/c) Control group consisted of three groups of animals: intact and mice received fine coal in the same concentrations as under the impact of the nanotubes. Under exposure to the maximal of the studied concentration of carbon nanotubes a significant change in the fine structure of the villi of the small intestine was found in the form of increasing the number of unstructured villi and proliferation of epithelial cells, most pronounced in duration of exposure until 2 months.

[Relationship of structural-functional (histological and cytological) parameters with cytogenetic and cytotoxic ones in the evaluation of the influence of environmental factors on the organism].

The paper gives an assessment of the association of structural-functional (histological and cytological), cytogenetic, and cytotoxic changes in the analysis of various exposures of the body during both experiments (oral acrylamide) and population examinations (impact of pulp-and-paper mill waste on the nasal and oral mucosae). The assessment of the association of the study parameters is shown to serve to more completely objectify the pattern of actuating factors.

[The cytogenetic status of children living in the vicinity of a pulp-and-paper mill].

To evaluate the cytogenetic and cytotoxic effects of a set of pollutions in the town of Koryazhma, the investigators made a complete karyological analysis (cytogenetic, apoptotic, and indirect proliferation parameters) of buccal and nasal epithelial exfoliative cells in two groups of old school age children living at various distances from a pulp-and-paper mill (PPM). The residential area that is adjacent to the PPM can be considered to be poor in the influence of genotoxic factors since there were 1.6- and 1.65-fold increases in cytogenetic disorders and cells with an atypically shaped nucleus, respectively, with a 1.57-fold reduction in the level of cell apoptosis. Karyological changes were revealed in the nasal mucosa, rather than in the buccal mucosa, which permitted one to recommend for the evaluation of the influence of environmental factors, the impact of ambient air pollution in particular, and to conduct cytogenetic studies on the cells of not only the buccal epithelium (that has been better studied), but also those of the nasal epithelium.

[Reactions of different cell populations of rats to intake of waters treated with physical methods].

A 6-month experiment was carried out to study the reactions of different cell populations of the testicle and duodenum of rats and the gastrointestinal tract of volunteers to the intake of 3 waters treated by physical methods: water conditioned with electric pulsed discharges; 2 waters obtained using energoinformational technologies: Grander water (Austria) and immunomodulated water Renorm (Russia). The test waters treated by physical methods were shown to have no negative effect or a positive effect on animals and man. Three used procedures to evaluate different gastrointestinal tract portions (oral and intestinal mucosae) of rats and volunteers revealed the preservation of the mucosal epithelium when Grander and Renorm waters are taken in doses.

[Impact of ambient air pollution by a pulp-and-paper mill on the cytological status of the nasal and oral mucosa in children].

The cytological state of nasal and oral mucosae in the children and adolescents living in the town of Koryazhma was evaluated at the schools located differently from the Kotlas pulp-and-paper mill (PPM). All the Kozyazhma children under examination were found to have an increased epithelocytic alteration index, which is likely to suggest cytotoxic exposure, which was shown to a greater extent with the duration of residence at the school more adjacent to the PPM. The first-form pupils from the school locates more closely to the PPM were found to showed a higher index of natural microflora colonization with buccal epitheliocytes and a trend for an increase in the epitheliocytic differentiation coefficient characterizing the high incidence of diseases.

[Non-invasive assessment used to evaluate the nasal and oral mucosal cytological status in sociohygienic monitoring].

By analyzing their own studies and the results of other studies by other investigators, the authors provide evidence that the noninvasive evaluation of the nasal and oral cytological status is one of techniques for assessing the health status and reflects the organism's state varying with environmental pollution, which enables it to be recommended for sociohygienic monitoring.

[Use of micronuclear test to assess drinking waters].

The effect of drinking waters with their altered structure and charge state (a total of 9 samples) on the epitheliocytes of the proventriculus, liver, and kidney was studied in rats after 6- and 12-month water consumption. It was found that in the absence of changes in the animals' morphofunctional status, the degree of water structuredness was associated with the frequency of epitheliocytes with nuclear protrusion into the proventricular mucosa following 6-month water consumption and with the manifestations of adipose degeneration, hepatocytic alterations, and stromal overgrowth into the liver after 12-month water use. The biological implication of little studied (additional) types of anomalies of the proventricular epitheliocytic nucleus: the necrotic nature of a perinuclear vacuole, the predominant implication of nuclear pyknosis and rrhexis to apoptosis and the association of binucleated patterns with the restorative proliferation of hepatic and renal tissues, was specified.

[Comparative toxicity of photosensitizers in varying destruction].

The toxicity of the photosensitizers proflavine acetate (PA) versus methylene blue (MB) was evaluated during their varying destruction. Under the influence of visible light, a partial (25%) transformation of the photosensitizers was shown to be attended by their enhanced toxicity and 100% destruction of the parent substances caused a reduction in their hazard. PA and its phototransformation products mainly affect the antiperoxide protection system and the structural and functional states of the liver, kidney, and duodenum. The maximum noneffective dose is 0.002 mg/kg. The possibility of using PA for water disinfection depends on the ratio of safe and effective concentrations. A partial (25%) MB destruction products cause mutagenic effects; the permissible dose of the mutagen is 0.00025 mg/kg. MB is not recommended for disinfection of all types of waters.

[Use of morphofunctional and cytogenetic studies to analyze the influence of environmental factors].

Long-term studies of 2 (cytohistology and genetic monitoring) laboratories of the Research Institute of Human Ecology and Environmental Hygiene, Russian Academy of Medical Sciences, to investigate the influence of environmental factors in the experiments made it possible to develop a noninvasive procedure for evaluating their cytological and cytogenetic impacts on man. A concurrent study of morphofunctional (histological, cytological) and cytogenetic parameters in both experimental and field trials can substantially extend and refine the interpretation of responses to environmental factors, which generates a need for using these parameters in hygienic and epidemiological studies.

[Cyto- and histological criteria for a risk of environment-induced diseases].

The author proposes morphological criteria determining the risk of environment-induced diseases. The experimental studies analyzing 23 indices of the development of reparative regeneration in the liver of rats exposed to environmental factors have revealed that a significant change in the ratio of uni- and binuclear tetraploid hepatocytes is a criterion for the risk of hepatotoxic effect. Evaluation of the cytological status of nasal and oral mucosae, by using 21 indices has indicated that a significant reduction in the proportion of individuals with the normal cytological status is a criterion for the risk of environment-induced diseases.

[The effects of fungous semination of dwelling environment on the cytological status of human mucosal membranes].

High level of fungous semination of dwelling environment is shown to have a destructive effect on mucosal membranes, which is manifested by their inflammation and allergic condition. The study of the cytological status of the nasal and oral mucosa proved its high sensitivity and significance when studying the influence of fungous semination of dwelling environment on the human organism.

[Structural and functional assessment of the body's status after consumption of the waters treated with various technologies].

The use of waters treated by different technologies was studied in animals and volunteers. Rats were used to study the use of the immunomodulated water "Renorm" alone and in combination with ozone-sorption treated Moscow tap water in a dilution of 1:10, that of the bottled water "Grander" (Austria) in combination with ozone-sorption treated Moscow tap water in a dilution of 1: 4 or 1:40; that of the water prepared by the Grander technology through a shower device when, after ozone-sorption purification, Moscow tap water was passed through a Grander shower device at a rate of 1 liter per min or 500 ml per 30 sec; that of the water electrochemically treated by an Izumrud (Emerald) installation. Moscow tap water served as a control for all waters and was Moscow dechlorinated water after ozone-sorption purification, by passing Moscow tap water from a tap into a 3-liter vessel through a household ozone device for 5 min and then passing it through a household coal filter (500 ml). "Troitsa" water also served as a control for Renorm water and as the basis for the water physically treated. The nasal and oral cytological status was followed up in different periods (before and a month after water use and 1, 2, and 6 months following a monthly use) in different groups of volunteers: control and placebo groups, and in the groups of the examinees after using the waters treated by energy-informational technologies (Renorm), and by the Grander technology. Experimental studies have revealed that the consumption of the waters in question not merely fails to cause negative changes in the viscera, but also improves a number of structural and functional indices and, in the volunteers, the use of the waters treated by the energy-informational technologies enhances the protective function of tissue barriers, such as the mucosae of the nose and mouth, by diminishing inflammatory reactions in these organs. Thus, both field and experimental studies have demonstrated that the use of the waters treated by different technologies results in structural and functional improvements.

[The informative value of determination of the cytological status of nasal and oral mucosae in the assessment of the quality of water].

The nasal and oral mucosal cytological status was studied in children of a control kindergarten who used boiled Moscow tap water and in those of two experimental kindergartens who had drunk bottled "Troitsa" water supplemented by a fortified "Zolotoy Shar" drink for 6 months. Impression smears were taken from their nasal and oral mucosae twice: before and 6 months after water use. The data presented indicate that the use of the water of improved quality in its trace and vitamin contents may be used in preventive and rehabilitative medicine as it leads to improvement of the nasal and oral cytological status, by normalizing and/or positively affecting the latter.
