[The impact of environmental air pollution and incidence of acute respiratory viral infections].

The paper characterizes diffuse ambient air pollution (P index) in accordance with the data of Kazan stationary stations in 1996-2000. The incidence of childhood respiratory diseases is studied for the same period. A correlation between morbidity and ambient air pollution is analyzed.

[Impact of environmental air pollution on dental morbidity in children].

Ambient air pollution was studied for its impact on the prevalence and severity of major dental diseases and on the biological age of pre-school children in ecologically tense and relatively pure regions. The lowest prevalence and severity of caries were registered in a nursery located in a control region. The mean number of permanent teeth was also more in children of the control group.

[Health status of preschool-children in areas with different man-made loads].

A questionnaire survey was made to study the opinion of residents in the area of the Yamashev-Dekabristy main road, the joint stock company Tasma-Holding, the commercial joint stock Orgsintez on their health status and on the source of ambient air pollution and the opinion of those living in Gorki-I, an ecologically pure area. The respondents were asked to answer the questions on the unfavourable impact of environmental factors on human health (respondents' painful sensations). The questions also concerned such factors as noise, odour, dust in relation to the place of residence near the main road or an industrial enterprise.

[Evaluation of ambient air pollution on children's morbidity with acute respiratory infections of the upper airway].

A relationship of ambient air pollution in the towns of Almetyevsk and Kazan to acute respiratory infection of the upper airways (ARIUA) in children was examined. Higher atmospheric pollution was found to cause an increase in the incidence of ARIUA. The correlation ratios for all the nosological entities studied ranged from 0.

[Ambient air pollution and human health in the town of Nizhnekamsk].

The paper gives hygienic characteristics of ambient air pollution and examines human health in the town of Nizhnekamsk. There are worse demographic indices. In the structure of morbidity, respiratory diseases make up the largest proportion (44.

[Incidence of pyelonephritis on territories with different levels of anthropogenic loading].

Relationship between atmospheric pollution with harmful substances and incidence of pyelonephritis was studied for the populations living in ecologically unfavorable and clean regions of an industrial city. Disease intensity and incidence were significantly higher in polluted regions, the probability of error being no more than p < 0.05-p < 0.

[Influence of environmental factors on physical development of preschool children].

A relationship between the ambient air pollution with noxious agents and the physical development of pre-school children residing in polluted and relatively "pure" areas was examined. The harmony of the morphofunctional status was found to be significantly lower in the polluted areas than in the "pure" ones, showing an error probability of no greater than p < 0.05 to p < 0.

[Effects of working conditions in the production of synthetic rubber on workers' health].

Examination of 325 Kazan workers engaged in the production of synthetic rubber revealed a high (35.6%) prevalence of thyroid pathology. Patients with thyroid disease and apparently healthy workers manufacturing synthetic rubber were found to have lower levels of T3, T4, and zinc and higher levels of thyroglobulin antibodies and chromium in the serum than in apparently healthy individuals not contacting with noxious agents.

[The diagnosis and surgical treatment of intestinal amebiasis].

Ninety-one patients with intestinal amebiasis (IA) were studied. All had been long suffering from IA due to the fact that it had not been diagnosed in time. Indications for emergency surgery were profuse hemorrhage, perforation of amebic ulcers, gangrene, and toxic dilatation of the large intestine.

[The diagnostic and therapeutic significance of thrombocyte functional activity and the factors in its regulation in chronic diseases of the large intestine].

To elucidate diagnostic value of platelet functional activity in chronic colon disease, we studied ADP-induced platelet aggregation (PA, in vitro) and cAMP concentration in blood plasma. If patients had chronic catarrhal, ulcerative colitis or chronic colon stasis, their serum cAMP appeared low, while initial rate of ADP-induced PA was high. The above alterations varied with the disease severity, in exacerbation and remission.

[The functional activity of the thrombocytes in chronic diseases of the large intestine].

Chronic diseases of the large intestine--catarrhal colitis, colonic stasis, unspecific ulcerative colitis, and amebiasis of the large intestine are attended by marked changes in the functional activity of blood platelets and factors of its regulation. They reflect the dynamics of the disease before and after operative and nonoperative treatment. A recurrence of the disease is linked with activation of blood platelets.

[Plasma histamine levels in various chronic diseases of the colon].

Patients suffering from chronic colitis, chronic stasis disease and nonspecific ulcerous colitis were examined for blood plasma histamine. The level of blood plasma histamine was found to be dependent on the intensity of the pathological process. The role of histamine in the development of disorders of neurohumoral regulation, microcirculation and motor and evacuatory function of the colon is discussed.

[The intestinal microflora in nonspecific ulcerative colitis].

On the basis of a complex clinical examination of patients with ulcer lesions of the large intestine it is concluded that differential diagnosis of ulcerative colitis should be based no microbiological, serological, immunological, endoscopic methods of examination. Complex conservative treatment should include both routine measures and bacterial agents.

[Qualitative and quantitative characteristics of atmospheric air pollution in an industrial city].

The data obtained as result of studies of qualitative and quantitative characteristics of urban ambient air give the ground to make a conclusion that air pollution in the areas of industrial enterprises is of a local character. A great part of urban territory is polluted with the major harmful impurities (carbon oxide, nitrogen dioxide, sulfur dioxide, dust). The studies carried out open up perspective to investigate the influence of harmful impurities on the population health and to develop activities aimed at the reduction of the level of chemicals' concentration in the air.
