[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.

[Prevalence and routes of transmission of pyloric Helicobacter infection. II. Transmission infection from an external source (literature review)].

Aim Of The Study: On the available reports to assess the possibility of the infection with pyloric Helicobacter (H.pylori) from external sources--via contaminated food and water. BASIC CONCEPTS: H.

[Scientific substantiation of perfection of sanitary bacteriological monitoring in drinking water use].

Criterion of the epidemic safety of drinking water is the absence of pathogenic and potentially pathogenic microorganisms. Currently, water quality control is performed in terms of the index of total coliform bacteria (TCB). TCB index oriented to the labile lactose sign has not sufficient relevance in the determination of the degree of the epidemic danger in the water use in relation to Salmonella and potentially pathogenic microorganisms.

[Prevalence and transmission pathways of the pyloric Helicobacter infection. Transmission from person to person (literature review)].

The purpose of review: analysis of the available in the literature data about the possible kinds and pathways of transmission of pyloric Helicobacter infection from person to person. Knowledge of these data is necessary for its prevention. Subjects--available literature, mainly English-language articles.

[Biochemical effects of chronic peroral administration of carbon nanotubes and activated charcoal in drinking water in rats].

Chronic 6-month experiment was carried out in rats, which received drinking water with multi-walled carbon nanotubes (MWCNTs), diameter of 15-40 nm, length ≥ 2 mkm) or activated charcoal (AC, diameter of 10-100 mkm), blood samples of the animals were used for assessment of biochemical markers. Both coal compounds induced the appearance of signs of oxidative stress 2 weeks after the beginning of the experiment and alteration of serum markers of liver and renal damage, as well as changes of cortisol and protein serum concentrations later Thus, despite of known high (asbest-like) inhalation toxicity of carbon nanotubes in comparison with other carbon allotrops (fullerenes and black carbon), we have found similar effects of MWCNTs and carbon microparticles in orally treated rats.
