The impact of multi-walled carbon nanotubes with different amount of metallic impurities on immunometabolic parameters in healthy volunteers.

The impact of two types of multi-walled carbon nanotubes (MWCNTs) (12-14 nm) with different content of metallic impurities (purified and unpurified nanotubes) on peroxidation processes, the status of immune cells in healthy volunteers and gene expression combined to pathway analysis was studied in vitro. From the study it was shown that the main mechanism of action for both types of MWCNTs is induction of oxidative stress, the intensity of which is directly related to the amount of metallic impurities. Unpurified MWCNTs produced twice as high levels of oxidation than the purified CNTs inducing thus more intense mitochondrial dysfunction. All the above were also verified by gene expression analysis of 2 different human cellular cultures (lung epithelium and keratinoma cells) and the respective pathway analysis; modulation of genes activating the NFkB pathway is associated to inflammatory responses. This may cause a perturbation in the IL-6 signaling pathway in order to regulate inflammatory processes and compensate for apoptotic changes. A plausible hypothesis for the immunological effects observed in vivo, are considered as the result of the synergistic effect of systemic (mediated by cells of the routes of exposure) and local inflammation (blood cells).

Effect of Maksar on antioxidant system in rats with type IIa alimentary hyperlipoproteinemia.

The development of type IIa alimentary hyperlipoproteinemia in rats was accompanied by changes in activity of glutathione-dependent enzymes, exhaustion of the reserves of antioxidant vitamins in the liver and blood, and intensification of lipid peroxidation. The hepatoprotective preparation Maksar obtained from far-eastern plants Maachia amurensis and containing natural biological antioxidants normalized blood lipid composition, corrected liver lipidosis, and improved the antioxidant defense system.

[Combined use of drinking mineral water and the natural enterosorbent zosterine in kidney stones (an experimental study)]. / K voprosy kompleksnogo ispol'zovaniia pit'evykh mineral'nykh vod i prirodnogo énterosorbenta zosterina pri nefrokal'tsinoze (éksperimental'noe issledovanie).

A combined action of carbonic mineral waters of Shmakovsky and Mukhensky deposits and natural enterosorbent zosterin was studied in nephrocalcinosis in experiment. Taking carbonic mineral waters reduced intoxication, stimulates filtration and excretory renal functions. Zosterin delays calcium in the renal tissue in nephrocalcinosis. Therefore, these two factors were incompatible in animals with experimental renal affection.

[The iron carbonate waters of the Maritime Territory]. / Uglekislye zhelezistye vody Primorskogo kraia.

Balneological and experimental examinations were made of physiological properties of carbonate iron mineral waters of the Primorskiy Territory. The waters were found perspective as a source of ecologically healthy water, to prevent diseases, to raise nonspecific resistance of the body.
