[Migration and differentiation of transplanted fetal neurogenic cells in animals with brain ischemia].

The migration, integration and differentiation of fetal neural progenitor cells (NPCs) in the ischemic brain have been studied. In our study the ischemic insult in FVB line mice was produced by occlusion of both carotid arteries during 20 min. A day after occlusion NPCs from GFP-transgenic 12.

[Increase in T-cell level in the peripheral blood of women with fractures in anamnesis during postmenopause period].

44 postmenopausal patients (45-76 years of old) have been observed. Interrelationship between composition and functional activity of peripheral blood cells, TNF-alpha level in the serum and bone density in postmenopausal women has been analyzed. It was established that the increase in neutrophil activity in women with osteoporosis, the high level of immune complexes are accompanied by the high level of IgG and autoantibodies to DNA.

[Role of genetic factors in the development of osteoporosis].

Osteoporosis which often accompanies the normal aging and a number of pathological conditions is closely related to bone remodeling disturbances. This process is provided mainly by the genesis of osteoblasts and osteoclasts, their activities and interactions. All the above in turn is dependent on numerous systemic and local regulatory factors such as hormones, nutrients, minerals, vitamins, cytokines, their receptors etc.

[Age and the vascular reaction to injury].

Our own results and the literature dates analysis showed that spontaneous endothelial cells injury in aging, and the hypertension, hypercholesterinemia, immune disorders, that was induced in experiment aggravating the process of the development of atherosclerosis.
