[Structural-functional approach to chronic cerebral ischemia in elderly people.].

The aim of the study - experience in implementing a structural-functional approach to chronic brain ischemia (CCI) in elderly people by combining simultaneously produced measurements. Object of research - elderly patients with CCI 1 stage. As a result of the study, the methodological experience of the system study of CCI from the standpoint of the structural and functional approach in the elderly is shown.

[Daily temperature gradients and processes of organogenesis in apical meristem of Cucumis sativus L].

We studied the influence of daily temperature gradients on organogenesis in apical and axil shoot meristems at different developmental stages in Cucumis sativus L. The level of organogenic activity of meristems was determined according to the number of leaf primordia on the main and lateral shoots, number of 2nd order shoots, and rudiments of flowers of different levels of development. At the studied ontogenetic stages (mesotrophic seedling or juvenile state), plants were grown under the controlled conditions: photoperiod 12 h, light intensity 100 Wt/m2, range of mean daily temperatures 20 .
