Saber-Toothed Cats (Carnivora, Felidae, Machairodoninae) from the Lower Pleistocene of the Taurida Cave, Crimea.

This paper describes the maxillaries of adult specimens of saber-toothed cats Homotherium crenatidens (Fabrini, 1890) and Megantereon sp. from the Taurida Cave (Crimea, Late Villafranchian; age, 1.8-1.5 Ma). We discuss the morphometric variability in the morphology of the upper carnassials and the length of the С1-Р3 diastema.

[The role of groups with high risk of tuberculosis in developing patients' contingents in the anti-tuberculosis clinics]. / Rol' grupp s riskom zabolevaniia tuberkulezom v formirovanii kontingentov protivotuberkuleznykh dispanserov.

The role of the highest tuberculosis risk groups in the enlargement of dispensary contingents increases under conditions of endemic tuberculosis decline while it is less manifest in the epidemiologically unfavourable regions. Risk contingents of polyclinics should be supplemented by a socially unfavourable group of subjects who together with patients having several risk factors and those with severe diabetes mellitus are the most vulnerable with respect to tuberculosis.

[Determining the optimal frequency of preventive fluorographic examination of the population]. / Opredelenie optimal'noi periodichnosti profilakticheskikh fliuorograficheskikh obsledovanii naseleniia.

The results relating to a 4-year observation of 62,000 residents of Alma-Ata based on individual cards of fluorographic examinations are presented. It is shown that the intensive indices on the incidence of pulmonary tuberculosis, lung cancer and x-ray-positive nonspecific diseases of the lungs as well as the proportion of neglected forms of the diseases increased with increasing of the intervals between the fluorographic examinations. The economic losses due to the diseases also increased. It is recommended that under conditions of increased incidence of tuberculosis fluorographic examination of adults and adolescents be performed annually while that of males at the age of 50 years or older be performed twice a year.
