[Calculation of prognoses of lung cancer in males from technogenic contamination of atmosphere in the Kemerovo region].

In this paper there are described the variants of the models of the regression analysis (linear exponential, exponential and hyperbolic) for the detection of relationships between the lung cancer rate in the male population and anthropogenic emissions in the Kemerovo region. After analyzing of the each model there was chosen the one seemed to be the most adequate to describe the dependence of cancer incidence from pollutant emissions into the atmosphere. At a later stage this model has served for the calculation of the medium-term forecasting of lung cancer rate in males in the dependence on the actual number of man-made emissions in previous years.

[Spread of carcinogenic and mutagenic effects in the population of Gornaia Shoria].

Mutagenic and carcinogenic effects were studied in the population of Gornaya Shoria, Kemerovo Region. The carcinogenic effects were evaluated on the basis of the data given by the Kemerovo regional cancer registry over 1990-2008. The standardized cancer morbidity index in Gornaya Shoria (342 per 100,000 population) exceeded the average index in the Kemerovo Region (286 per 100,000) in the same period. The mutagenic effects were estimated on the basis of the monitoring data on the frequency and spectrum of chromosomal aberrations in the peripheral blood lymphocytes of the dwellers of Gornaya Shoria for the 1992-2009 period. The mean level of chromosomal aberrations (5.31%) in the residents of Gornaya Shoria was found to be greater than the regional background mutation rate (2.86%) (p < 0.001). The values of individual aberration types (chromatid and chromosomal breaks, as well as chromosome-type exchange aberrations) were significantly higher in the dwellers of Gornaya Shoria than those in the basic control group. The revealed high mutagenic load in the inhabitants of Tashtagol District, Kemerovo Region, allows this area to be assigned to high genetic risk ones.

[Benz(a)pyrene antibodies are a marker of carcinogenic load in coal-processing workers].

The authors studied benz(a)pyrene-specific secretory and serum antibody ratios (Ka) in 249 workers of the Kemerovo Power Station, by applying their modified enzyme immunoassay technique. There were 37 (20.5%) and 4 (5.8%) cases with Ka >2 at the preset immunoassay parameters of the 180 and 69 workers of mainline production and auxiliary units, respectively. A Ka value of >2 was found in 35 (21.6%) of the 162 males and only in 6 (6.9%) of the 87 females of the whole sample, in 29 (26.1%) of the 111 smokers and in 12 (8.7%) of the 138 non-smokers. The technique is proposed to study specific immune reactions and exposure to carcinogens primarily in workers of the enterprises processing coal and other types of fuel.

[Quantitative characteristics of chromosomal aberration frequency in the residents of the regions with different levels of cancer incidences].

We present the results of cytogenetic monitoring of the districts in Kemerovo region, which differ in standardized indices of cancer incidence. It has been shown that residents of the districts with high incidence of malignancies had higher average frequency of metaphases with chromosomal aberrations than the control group (4.06 +/- 0.12% and 2.76 +/- 0.13%, respectively). This difference is caused primarily by single or paired fragments. The increase in the frequency of aberrant metaphase incidence in the districts with elevated cancer frequency was observed both in the male and female groups as well as both in adults and children.

[The morbidity of stomach cancer among the workers of key industries of the Kuznetsk Basin (Kuzbas)].

The data research of the retrospective analysis of the morbidity of stomach cancer in the Kirov oblast (1990-2005) is presented. The dependence of morbidity rate from the volume production and processing of coal is established. The forecasting of morbidity rate of stomach cancer is estimated up to 2013 considering the factual indicators of volume of output in the key industries of Kuzbas.

[Impact of atmospheric by-product-coking emission on malignancy morbidity].

A statistically significant direct strong correlation was found and an interval was determined between the annual volumes of atmospheric emission from OAO "KOKS" and the standardized (lung, gastric, skin, thyroid, breast, and ovarian) malignancy morbidity rates in Kemerovo. There were gender differences in the incidence of malignancies. The calculated regression coefficients can predict a probable rise in malignancy morbidity in Kemerovo from 2010 due to the increased volumes of atmospheric emission by OAO "KOKS since 2001.

[A new immunoassay of human antibodies to chemical carcinogens].

The study was undertaken to optimize the well known immunoassay of antibodies to chemical carcinogens, designed by J. Chagnaud et al., and examine the specific features of the generation of antibodies (Ab) to benzo[a]pyrene (BP) in patients with lung cancer. Ninety-two serum samples from healthy males and 80 samples from patients with lung cancer were studied. Increased efficiency was achieved by the use of bovine serum albumin instead of thyreoglobulin in the synthesis of carrier protein conjugates with BP. Better reproducibility was accomplished, by using the control serum sample with the known content of IgM, IgG, and IgA Ab to BP. Analysis of the study serum samples has established that in healthy male smokers, the count of IgA Ab was twice greater than that in non-smokers. The patients with lung cancer were found to higher levels of IgG and IgA Ab to BP (in both smokers and non-smokers) than healthy individuals. It is proposed to use the stated method to study a role of A to chemical carcinogens in the pathogenesis of malignancies.

[Retrospective analysis and prognosis of lung cancer morbidity in Kouzbass].

The authors present results of retrospective analysis of lung cancer morbidity in Kouzbass from 1990 to 2005. The morbidity parameters appeared to depend on volumes of coal mining and treatment. Prognosis of lung cancer incidence was calculated up to 2014 with consideration of actual volumes of coal mining and treatment.

[Ambient air benz[a]pyrene and cancer morbidity in Kemerovo].

A statistically significant direct strong correlation was found between the annual average daily concentrations of air benz[a]pyrene and the lung and the gastric cancer morbidity rates in males and females, skin, thyroid, and ovarian cancer in females. The certain interval of the measured concentration of benz[a]pyrene and the recorded morbidity rate was shown to be characteristic of each of the above-mentioned tumors.

Immunological images of polycyclic aromatic hydrocarbons.

AIM: To develop experimental model for definition of immunological images of chemical carcinogens. MATERIALS AND METHODS: The conjugates of benzo[a]pyrene, benz[a]anthracene, anthracene, chrysene and pyrene with bovine serum albumin and yeast hexokinase were synthesized. Rabbits were immunized by bovine serum albumin-hapten conjugates. Antibodies to each hapten were isolated from the serum by affinity chromatography with the hapten-yeast hexokinase-Sepharose sorbents. The binding of each hapten with each antibody was determined by competitive immunoassay. RESULTS: The immunological images of all the investigated chemical compounds were described. CONCLUSION: The model is proposed to determine the internal immunological images of anti-idiotypic monoclonal antibodies to chemical carcinogens.

[Complex analysis of mutagenic and carcinogenic jeopardy of work conditions on JSC "Cox" in Kemerovo].

The authors present results of complex study concerning mutagenic and carcinogenic effects of work conditions in chemical-recovery industry. Oncologic morbidity and frequency of chromosomal aberrations in workers group is considerably higher than in controls. These effects appear to increase in males with longer length of service.
