The morpho-functional characteristics of lymphoid organs and walls of the small intestine when consuming waters of various composition
Objective: To study the nature and dynamics of structural changes in the wall of the small intestine, organs of the lymphatic system with long-term consumption of waters of different composition. Scientific novelty of the study: For the first time, a complex study of morpho-functional parameters of the small intestine wall, associated with it lymphoid formations - Peyer's plaques, as well as lymphoid organs (mesenteric and iliac lymph nodes, spleen, thymus) in response to short-term, medium duration and long-term Drinking by animals in a drinking regime of waters of different composition. The obtained data show that irrespective of the type of water in the organs under study, structural transformations take place, indicating their adaptive nature.
For science it is important to solve the problem of accuracy using demineralized water (distilled, bidistilled passing through milipore filter, etc.) in biological and medical experiments. Developed at the Institute of Colloid and Water Chemistry NAS of Ukraine integrated approach to water quality bioassay allows you to objectively assess its impact on the livelihoods of different organisms [1, 2]. Its essence is that at the level of the body analyzed responses from different taxonomic groups and trophic levels - plants, invertebrates and vertebrates (ie determined general and acute toxicity of water), and at the level of cells - structural and functional changes in genomes (it turns genotoxicity and cytotoxicity). Obtained using this approach, data can be used for objective assessment of the impact of such water on human health.
As a result of systematic studies of drinking water in Kiev found a significant number Micromycetes, indicating that their ability to adapt to extreme conditions, without succumbing to the traditional means of disinfection. It is found micromyceta hazardous naselen- tion? In answering this question, the authors of this article outlined the extent of the problem of providing drinking water quality, emphasizing voice- hidnosti developing new approaches to address it.
The results of a
comprehensive assessment of water quality from the trade network in Kiev are
presented using analytical chemistry, biotesting using a set of animals and
plant test organisms, and microbiological analysis. The criterion for assessing
water quality was the integral indicator in conventional units, which allowed
to classify the studied waters in one of four categories: "not
dangerous", "conditionally dangerous", "dangerous" and
of the thesis (part of the abstract) On the theme "Ecological and
microbiological monitoring of drinking water quality in the city of
Saratov". The relevance of the topic. The water of open reservoirs is a
natural habitat for a variety of microorganisms coexisting in the form of
complex associations - micro biocoenoses, the quantitative and qualitative characteristics
of which can vary significantly under anthropogenic influences (Netrusov et
al., 2000; 2005; Bukharin, Nemtseva, 2008). These changes must be taken into
account when conducting microbiological monitoring of water bodies. The problem
of population security. Saratov high-quality drinking water is relevant and is
associated with a change in the natural properties of the water of the
Volgograd Reservoir, the main source of water supply, under the influence of
The development of the Vital Block water treatment system took into account many factors of our reality and related needs, so these filters can be used in various fields and for various purposes.
Drinking water with low salinity helps wash out salts from the body. Changes in the water-salt balance in the body were noted not only with the use of demineralized water, but also water with mineralization from 50 to 75 mg / l. Therefore, a group of WHO researchers, which produced a report for 1980, recommends consuming potable water with a mineralization of 100 mg / l at least in potable purposes.
