[Modern medical and meteorological assessment of Moscow weather and the effectiveness of non-drug methods of increased meteosensitivity correction in patients with joint diseases]. / Sovremennaya mediko-meteorologicheskaya otsenka pogody Moskvy i effektivnost' nemedikamentoznykh metodov korrektsii povyshennoi meteochuvstvitel'nosti u patsientov s zabolevaniyami sustavov.

Weather is one of the leading negatively acting on the human body factors. Abnormal regimes and extreme hydrometeorological and geophysical phenomena form the most biotropic external conditions that can have a negative effect and provoke weather-related exacerbations in people with chronic non-infectious diseases. Today, the problem of the climatic and weather factors influence acquires a new content and becomes relevant in connection with the global climate change and its regional manifestations. PURPOSE OF THE STUDY: To scientifically substantiate the need for medical and meteorological monitoring to determine the most biotropic weather conditions in the Moscow metropolis and to evaluate the meteorological effectiveness of non-drug rehabilitation methods. MATERIAL AND METHODS: 335 patients diagnosed with osteoarthritis of various locations, and after total hip and knee arthroplasty, were included in the study. Patients were divided into 4 groups: 67 patients of the 1st group received "dry" carbonic baths and exercise therapy; general radon baths and exercise therapy were prescribed to 60 patients of the 2nd group; 61 patients of the 3rd group received general sodium chloride baths and exercise therapy; 84 patients of the 4th group got local cryotherapy and exercise therapy procedures. The study of weather sensitivity was carried out by the questionnaire method. Psychological examination was carried out using the tests HAM (health, activity, mood), Mini-Mult (Abbreviated multifactor questionnaire for personality research) and HADS (Hospital Anxiety and Depression Scale). RESULTS: 272 (81.2%) patients had increased meteosensitivity, which was accompanied by mild manifestations in 24.3%, moderate severity in 48.2%, and severe ones in 27.5%. The effectiveness of the balneotherapy and cryotherapy methods was confirmed by positive dynamics and a clear regression of meteopathic reactions in 76.1% of patients after a general radon therapy and in 61.7% after «dry¼ carbon dioxide baths. Total sodium chloride baths did not have a significant meteorological effect. However, a positive trend in psychological testing indicators was noted, which indicates an improvement in psychological adaptation after a course of treatment. Local cryotherapy procedures helped to reduce only severe meteopathic reactions from 14.3 to 8.3% and improve the psychoemotional state, which may be the choice when it is impossible to use balneotherapy. CONCLUSION: The increase in the frequency of biotropic weather conditions (hypoxic and spastic) is observed in the climate of the Moscow metropolis. This contributes to the increase and aggravation of the meteopathology manifestations. The effectiveness of non-drug methods in the prevention of increased meteorological dependence in patients with joint diseases has been proved.

[Role of opisthorchis felineus on induction of bile duct cancer].

Opisthorchis felineus (Trematoda) is widespread in the Russian Federation, especially in Siberia, and other countries of Europe. Infestation of endemic area population with O. felineus reaches 80%. On animal models of the infection of closely related Opisthorchis viverrini combined with the nitrosamines' intake it has been shown that the parasite induces cholangiocarcinoma. However carcinogenic potential of O. felineus is still poorly studied. The present study is aimed to investigate the role of O. felineus in cholangiocarcinoma carcinogenesis in hamster treated additionally by dimethylnitrosamine (DMN). Golden hamsters were divided into 4 groups (15 specimens in the control group and 20 for other groups): (I) untreated control, (II) 12.5 ppm DMN solution intake, (III) infected with 50 metacercariae of O. felineus and (IV) infected with 50 metacercariae of O. felineus and 12.5 ppm DMN solution intake. According to the histological data, in the. O. felineus-infested group significant hyperplastic and dysplastic biliary changes were found considered as a precancerogenic state. Such pathological changes of bile ducts were more severe in group treated with both factors, with cholangiocarcinoma being found out at 18th week in all the animals of this group. These results demonstrate that O. felineus could play promoting role in two-step model in cholangiocarcinoma carcinogenesis and may be used to define the O.felineus group in the International Agency for Research on Cancer classification of agents, mixtures and exposures (IARC categories).

[The biotropic weather conditions and changing the clocks as the extraneous risk factors of weather-dependent exacerbations of chronic diseases].

This paper reports the results of medico-meteorological investigations suggesting the influence of biotropic (unfavourabe) weather conditions characteristic of transient seasons in combination with the abolition of on the frequency of application for emergency medical aid. It was shown that the abolition of during the period from 2009 to 2013 resulted in a significant rise in the frequency of application for the emergency treatment of exacerbation of cardiovascular diseases. The sociological studies involving the responders of various social and age groups carried out parallel to the medical ones demonstrated that most of them (77%) considered the abolition of to be the main cause of the deteriorated of the sense of wellbeing and emphasized the necessity of winter time reversal.

[Degree of purification of a chemical epidemic typhus vaccine of the heterogeneous ballast proteins]. / Izuchenie stepeni ochistki khimicheskoi sypnotifoznoi vaktsiny ot ballastnykh geterogennykh belkov.

The degree of purification of chemical typhus vaccine from the ballast proteins of the substrate has been studied by chemical and immunochemical methods. The analysis of 11 production batches of the vaccine and a number of model preparations has revealed that chemical typhus vaccine is completely free from nonprotein nitrogen-containing components and, to a considerable extent, purified from ballast protein, its concentration being 0.033-0.242 mg per vaccination dose, and also possesses a high specific activity (198-1454 antigenic units per mg of protein. Ballast proteins include at least 5 egg antigens. The concentration of one of them varies between 0 and 5 micrograms per dose. A number of recommendations is made; their realization will make it possible to increase the degree of purification of chemical typhus vaccine.

[Standardization of preparations intended for the serodiagnosis of arboviruses]. / Standartizatsiia preparatov, prednaznachenykh dlia serodiagnostiki arbovirusov.

As the result of our research work, 3 reference preparations have been first obtained and studied in accordance with all requirements of biological standardization. These preparations are the national standard of yellow fever antiserum and immune ascitic fluids (IAF) used as reference reagents: IAF to tick-borne encephalitis virus and IAF to Japanese encephalitis virus. The new preparations are stable, possess sufficient specific activity and can be used as standard preparations for the identification of the above-mentioned viruses.
