[The introduction of the multilevel system of medical care for stroke patients in the Tatarstan Republic]. / Opyt vnedreniia mnogourovnevoi sistemy okazaniia meditsinskoi pomoshchi bol'nym s insul'tom v Respublike Tatarstan.

The analysis of introduction of multilevel system of medical care by the patient with a stroke in the Tatarstan Republic for 2008-2013 is carried out, results of efficiency of these changes are given.

[Results of introduction multilevel system of medical care to the patient with a stroke in the Tatarstan Republic].

Introduction of the multilevel system of medical care to the patient with stroke in the Tatarstan Republic for 2008-2012 and formation of vascular centers are analyzed. There is a positive trend in some indices (stroke morbidity, treatment efficacy, fatality, number of functionally independent patients etc).

[Cytogenetic study of certain Tilia species]. / Tsitogeneticheskoe izuchenie nekotorykh vidov roda Tilia L.

The number of chromosomes, and mitosis and microsporogenesis were studied in Tilia europaea, T. tomentosa, T. cordata and T. platyphyllos under natural conditions of Voronezh region. Significant mixoploidy of meristematic tissue cells in seedling root tips, mitotic activity and meiosis have been demonstrated for the first time. The number of chromosomes in somatic cells varied from 28 to 140-146. The number 2n = 82 was modal for all the studied species. The number of chromosomes in T. europaea has been determined for the first time. The numbers of chromosomes in the genus Tilia are analysed on the basis of the literature and our own data. The peak of mitotic activity in seedlings and juvenile leaves (8-10%) fell on the night: 0-1 a.m. according to the winter time. Microsporogenesis is simultaneous and asynchronous. In some individual trees various abnormalities of meiosis were found: lagging in time in 1 to 5-6 chromosomes, bridges, fusions of spindles. Variations in pollen dimensions, shape and pore number were detected in many trees.
