THE ANTITUMORAL IMMYNITY. THE MORDERN VIEW ON THE STRESS AND DEATH OF TUMOR CELLS
This review summarize the state-of-the-arts of cancer immunity. Recent advances suggest that apoptosis can be immunogenic. Tumor cells may be «stressed» before death by different signal that lead to their immunogenicity. As the response on chemotherapy or radiotherapy, tumor cells can express «danger» and «eat me» signals on the cell surface or can secrete immnnpgtimiifatnry factors to stimulate immune effectors.

INFLUENCE OF GENE HLA DRB1*04 ON OCCURRENCE AND CURRENT OF RHEUMATOID ARTHRITIS
Researched presence of gene HLA DRB1*04 at patients with rheumatoid arthritis in comparison with healthy donors. Following data have been revealed: at patients with rheumatoid arthritis gene HLA DRB1*04 met in 55 %, at healthy donors in 15 %. The interrelation between frequency of revealing a gene and weight of current of disease is revealed: at patients with presence of gene HLA DRB1*04 it was marked higher activity the diseases sick with the given gene in most cases (89 %) were positive on rheumatoid factors that causes heavier current rheumatoid arthritis.

ANTIBACTERIAL ACTIVITY OF NEUTROPHILS IN «SIRS-I», «SIRS-III» AND SEPSIS BY PATIENTS WITH BURN
In this study, we investigated indexes of haemogramma and antibacterial activity of neutrophils in «SIRS-I», «SIRS-III» and sepsis by burn patients. In patients with «SIRS-I» and «SIRS-III» was shown leucocytosis with immature form cells; common antibacterial potential and intracellular killing activity of neutrophils were the same, as in healthy people. However, leucocytosis, common antibacterial potential and intracellular killing activity of neutrophils in sepsis were lower, than in «SIRS-I» and «SIRS-III». Remarkably, antibacterial activity of neutrophils «in vitro» as regards to E. coli was significantly higher than to St. aureus.

In research necessity of practical application of the special methods has been considered, allowing define pour markers of resistance to antibiotics at the is conditional-pathogenic microorganisms allocated from a clinical material. It is revealed, that the microorganisms possessing markers ofresistency to antibiotics, can be regarded in a routine practice as sensitive, that leads to a clinical inefficiency of the antibacterial therapy.

Germline mutation rates at eight minisatellite loci (B6.7, CEB1, CEB15, CEB25, CEB 36, MSI, MS31 and MS32) have been studied among the irradiated families from the Techa River population and non-exposed families from the same area. The groups were matched by ethnicity, parental age, occupation and smoking habit. A statistically significant increase in mutation rate was found in the germline of irradiated fathers, whereas maternal germline mutation rate in the exposed families was not elevated. Minisatellite mutation rate in the germline of irradiated fathers did not significantly correlate with the dose-rate at the time of conception. The frequency of minisateUite mutation in the children of irradiated parents did not show any correlation with the doses of in utero exposure to the bone marrow and soft tissues.

THE ADAPTIVE CAPACITIES OF PERIPHERAL BLOOD LYMPHOCYTES OF PEOPLE, EXPOSED TO INFLUENCE OF CHRONIC IONIZING RADIATION TREATMENT
The effectiveness of DNA repair and apoptosis mechanisms in peripheral blood lymphocytes of people, affected by chronic radiation exposure, and also capacity of these cells to form an adaptive response was estimated by using neutral variant of comet assay method. The tendency was observed in the experimental group of people, that all comet parameters where lower than in control group. Statistically significant differences between the rates of DNA fragmentation in the samples before acute radiation exposure of the cells, after this exposure and 2 h. later was not seen in the experimental group as well as in the control group. However, the individual cases of an adaptive response and the radiation hypersensitivity was observed in the both groups in these moments of time after irradiation. It was suggested, that an activity of cell protective systems such as DNA repair and apoptosis regulation in the every case depend on individual habits of each of examined human.

It was revealed that there is a statistically significant increase of spontaneous abortions and cases of early neonatal mortality frequency with the increase of the ovarial dose and dose to bone surfaces. Besides the level of significance was higher for the dose to bone surfaces. The frequency of preterm labour significantly correlated only with the dose to bone surfaces. Joint frequency of untoward pregnancy outcomes (congenital developmental defects, stillborn children and early neonatal mortality) also showed statistically significant correlation only with the dose to bone surfaces.

The object of this research is the diet of perch in the shallow lake Sineglazovo during the under ice period, It has been discovered that 4-year-old species chiefly consume plankton crustaceans. Perch of this age group consuming zooplankton was seldom noted, that can be connected both with the complicated alimentary relations within the ichthyocenose and the intensive development of plankton organisms under the conditions of organic pollution.

The data presented in the article are devoted to the results obtained while examining the Shershnyovskoye reservoir’s coastal strip and water-collecting area in the range of the 2nd and 3d ring sanitary control zone. The Shershnyovskoye reservoir is Chelyabinsk’s source of utility and drinking water supply and a place where people rest. The reservoir is exposed to intensive anthropogenic load. This results in deterioration of water quality and reservoir’s ecosystem. The inventarizataon of sources polluting the reservoir has been conducted. The sources have been ranked on the basis of the extent to which they are environmental hazard.

TUBIFEX TUBIFEX (TUBIFICIDAE) SURVIVAL AND FERTILITY UNDER LABORATORY KEEPING AND BREEDING
There is no any standard methods for estimate toxicity of sediments using bentic organisms in Russia today. Tubifex tubifex is one of widespread freshwater zoobentic invertebrates. It can be used to create aquaculture for developing test-system for assessment of sediment toxicity. We have developed approaches for longtime cultivation ofTubificidae. During 8 months of cultivation an average fertility of worms was 1,82±0,23 cocoons / individual per 2 weeks. Average survival was 86,7 %. We discovered the variation of reproduction T, tubifex for 8 months. We found high effectivity of I tubifex cultivation at an age of 6-8 months.

THE ASSESSMENT OF DIFFERENT FACTORS INFLUENCE ON CYANOBACTERIAL TOXICITY
Research results on the toxicity of cyanobacterial blooms from the Shershni reservoir (Chelyabinsk region) are presented. In summers of 2005-2007 LD50 of cyanobacteria varied widely (from 48 to 572 mg/kg). The factors influencing the toxicity are analysed. No effect of temperature, year, month, dominant genus on the toxicity is determined. The inverse relation between the total number of cyanobacteria in water and their toxicity is showed. Besides the percentage composition of cyanobacterial genus in bloom is shown to has an influence on the toxicity.

The aim of this study is to assess die capacity of electromagnetic agents (electromagnetic fields with linear, right, left polarization, frequency 925 MHz and modulation 217 Hz; electric field 217 Hz, magnetic field 217 Hz) to induce genotoxic effects. The mice CBA line were subjected once for 10 minutes to pulse electromagnetic radiation modulated as a GSM standard with the power density 1.2 mW/cm2, electric field 300 W/m, magnetic field 0,7 A/m andy-irradiation, 15 cGr. The polychromatic erythrocytes (PCE) and normochromatic erythrocytes (NCE) in the marrow were examined to determine the extent of micronuclei and PCE/NCE correlations. The electromagnetic exposure significantly increased the frequency of micronucleated PCE and NCE in comparison with sham-irradiated mice. There was no difference in the proportion of PCE/NCE between exposed and unexposed animals.
