[Toxicological sanitary characterization of titanium dioxide nanoparticles introduced in gastrointestinal tract of rats. Communication 2. Intestinal microbiocenosis condition and allergic sensitivity].

Intestinal microbiocenosis condition, cytokine IL-6, IL-10 and TNF-alpha levels and allergic sensitivity in experimental systemic anaphylaxis test were studied in rats that received intragastrically nanoparticles of titanium dioxide. The results obtained were discussed from the standpoint of possible health risks related to nanodimensional titanium dioxide exposure.

[Toxicological and hygiene characterization of titanium dioxide nanoparticles introduced to the gastrointestinal tract of rats. Communication 1. Integral, biochemical and hematologic indices, small intestinal macromolecule absorption, DNA damage].

Water suspensions of titanium dioxide nanoparticles were introduced intragastrically to growing male Wistar rats daily for 28 days. The data obtained revealed the presence of toxic risks related to said nanomaterials action and demonstrate the necessity of sanitary regulation of titanium dioxide nanoparticles used in food contact materials, cosmetics and other commodity.

[Nanotechnology in food production: advances and problems].

Presented article is a review of the modern data on nanotechnology use in food manufacturing. There are discussed the basic scopes of nanotechnology application in food industry. One of the main problems arising in connection with introduction of nanotechnology in food, is an absence of reliable methods of identification and the control of nanoparticles is in structure of foodstuff including the control of their authenticity.

[Silver nanopacticles in industry, environment and food packaging material: probable risk characterization].

Nowdays nanotechnology obtains wide use of in industry and agriculture. One of the most perspective and widespread nanomaterials is nanosilver. In this article we focused on the prospects and advantages of the following nanomaterial and also described the risks for humanity and environment.
