[Immunological status of patients with caries and its complications in combination with parodontitis].

Results of complex clinical and immunological study of patients with caries and pulpitis in combination with periodontitis were presented. It was revealed that high intensity of caries and parodontitis combines with significant disturbances in cellular and humoral parts of immune system.

[Efficacy and safety of bivalos therapy for postmenopausal osteoporosis. Results of Russian multicenter trial].

Aim: To study effects of one-year therapy with bivalos on mineral bone density (MBD) of the spine in patients with postmenopausal osteoporosis (PMO), effects of bivalos (strontium ranelate) on MBD of the neck of the femur and femur, the levels of bone metabolism markers, quality of life, tolerance of long-term therapy.

Material And Methods: The study was made of 60 females aged 54-75 years with PMO. MBD was measured with x-ray absorptiometry in the vertebra and proximal femur.

[Osmoadaptation in representatives of haloalkaliphilic bacteria from soda lakes].

The adaptation of microorganisms to life in brines allows two strategies: the accumulation of organic osmoregulators in the cell (as in many moderate halophiles, halomonads in particular) or the accumulation of inorganic ions at extremely high intracellular concentrations (as, for example, in haloanaerobes). To reveal the regularities of osmoregulation in haloalkaliphiles developing in soda lakes, Halomonas campisalis Z-7398-2 and Halomonas sp. AIR-2 were chosen as representatives of halomonads, and Natroniella acetigena, as a representative of haloanaerobes.
