RESUMO
The effect of individual components of humic substances of peloid on free radical oxidation processes has been investigated under conditions of oxidative stress induced in albino rats. Biological activity of peloids was determined using such parameters as the general antioxidant activity, activity superoxide dismutases, catalases and glutathione peroxidases on the third and tenth day of the experiment. Results indicate that the state of oxidative stress can be corrected on the third day of the experiment. Humic acids restore not only normal physiological redox systems, but also increase the activity of antioxidant enzymes on the 10th day.

Materials of investigation of Legionnaires' disease outbreak in one of the town of Sverdlovsk region in summer 2007 are presented. Outbreak arose in situation of epidemiologic welfare on majority of registered infectious diseases. Epidemiologic diagnostics of the outbreak has been performed in maximal shorttime interval, during which it was necessary to investigate variety of miscellaneous versions. Active search of the source of the infection and its transmission factors resulted in desired result and allowed to terminate the outbreak in 14 days.

Materials of investigation of Legionnaires' disease outbreak in town Verkhnyaya Pyshma (Sverdlovsk region) are presented. Features of epidemic process during this outbreak were reflected, its epidemiologic characteristics were described. Effectiveness of timely antiepidemic measures directed at elimination of main factor of infection's transmissibility was shown.

Peloid preparations may influence activity of some oxidoreductases (lactate dehydrogenase, malate dehydrogenase). Their effects depend on physico-chemical properties of the compounds tested.
