[Socio-medical aspects of injuries on the Baikal-Amur main line].

In the past 10 years, the total rate of traumatism on the Baikal-Amur main line has reduced by 15% at the expense of occupational traumatism, whereas the rate of non-occupational injuries is on the rise. Males (86%) are prevalent among the victims. The most all-bodied persons (aged 21-40 years) account for 85.

[Development of medical and biological research in Eastern Siberia].

The impact of the North conditions on the human body has been studied. There are high morbidity and mortality rates, abnormal pregnancy, premature and abnormal labors, and congenital malformations in the newborn. A complex of medical and prophylactic measures has been worked out to protect human health as a result of the studies of the regularities of general and occupational diseases at some enterprises in the Far North, Yakutia, and Buryatia.

[Means for optimizing epizootiological research and territorial disease eradication].

The authors emphasize the usefulness of parallel studies, based on monitoring the most important components of the parasitic systems of several nosologic forms, co-inhabiting the studied territories. Such studies will improve the informative value of the data and reveal the common regularities in the development of sympatric foci of zoonoses. The knowledge of such regularities will help develop ecologically safe methods for regulation of the foci and sanitization of the territory.

[Possibilities for the polyclinic cardiologist in treating hyperlipoproteinemias in men with risk factors for ischemic heart disease].

A total of 158 males with coronary risk factors and excessive (4 to 55% above normal) body weight were treated by diet and exercise for hyperlipoproteinemia in an out-patient clinic for 18 months. Blood cholesterol decreased significantly, by 14.4% (p less than 0.

[Isolation of Tamdy virus (Bunyaviridae) pathogenic for man from natural sources in Central Asia, Kazakhstan and Transcaucasia].

Isolation of 47 strains of Tamdy virus (Bunyaviridae) in the Uzbek SSR, Turkmen SSR, Armenian SSR, Kazakh SSR, and Kirghiz SSR was analysed. Thirty-two strains were isolated from Hyalomma asiaticum ticks in which transovarial transmission of the virus was demonstrated. Three subspecies of H.

[Properties of Hav6Neq2 and Hswl(H0)Hav2 influenza viruses isolated from waterfowl in southern Turkmenia].

Three influenza A virus strains were isolated from shorebirds in October, 1977, in southern Turkmenia, in the vicinities of Tedzhen water reservoir. From a common tern, A/Sterna hirundo/Turkmenia/45/77 strain was isolated with the antigenic formula Hav6Neq2, from a teal and a black-headed gull influenza A/Anas crecca/Turkmenia/4/77 and A/Larus ridibundus/Turkmenia/13/77 strains with previously unknown combination of surface antigens Hswl(H0)Nav2 were recovered. By the molecular weight of the heavy (HA1 59,000 d) and light (HA2 24,000 d) chains of hemagglutinin, the Turkmenian viruses A/Larus ridibundus/Turkmenia/13/77 and A/Anas crecca/Turkmenia/4/77 are similar to each other and to the strains having H0 hemagglutinin: A/PR8/34 (H0N1) and A/Whale/PO/19/76 (H09Nav2).

[Chim virus, a new arbovirus isolated from ixodid and argasid ticks collected in the burrows of great gerbils on the territory of the Uzbek SSR].

Five strains of hitherto unknown arbovirus designated Chim by the place of primary collection of ticks was isolated from Ixodid and Argasid ticks collected in the Uzbek SSR in burrows of great gerbils. The virus has no antigenic relationships with arboviruses previously isolated from ticks, its size varies from 100 to 220 nm, it contains RNA and has a lipid-containing envelope. Chim virus is pathogenic only for suckling mice by the intracerebral route and exerts cytopathic effect in continuous L, Rh, BHK cell lines.

Virus "Tamdy"--a new arbovirus, isolated in the Uzbee S.S.R. and Turkmen S.S.R. from ticks Hyalomma asiaticum asiaticum Schulee et Schlottke, 1929, and Hyalomma plumbeum plumbeum Panzer, 1796.

Eleven virus strains were isolated from ticks Hyalomma asiaticum asiaticum Schulce et Schlottke, 1929, and Hyalomma plumbeum plumbeum Panzer, 1796,collected in 1971-1974 in desert regions of the Uzbee S.S.R.

"Karshi" virus, a new flavivirus (Togaviridae) isolated from Ornithodoros papillipes (Birula, 1895) ticks in Uzbek S.S.R.

Three identical strains of an arbovirus were isolated from 475 Ornithodoros papillipes ticks collected in June, 1972, in burrows of the great gerbil (Rhombomys opimus Licht., 1882) in the environs of Beshkent, Karshinsk steppe, Uzbek S.S.
