Structure of human vertebral lamellar bone in age-associated involution and osteoporosis.

We compared the structure of lamellar bone in anterolateral zones of vertebral bodies in adult and senile subjects in health and osteoporosis. The appearance of structural signs of age-related osteopenia and enlargement of coplanar consolidations of the bone matrix crystals were noted. Osteopenia was more pronounced in osteoporosis, while the structural organization of the mineral component did not differ from that in age-matched controls.

Water status and LPO in rat tissues during massive blood loss and irradiation with He-Ne laser.

We revealed a relationship between water balance and LPO in the myocardium, liver, and blood plasma during massive blood loss and irradiation with He-Ne laser. Low-intensity laser irradiation of the plasma inhibits LPO and normalizes water balance in rat tissues during massive blood loss.

Comparative study of Saccharomyces cerevisiae LPS.

LPS of yeast strains producing human epidermal growth factor were studied. Experiments demonstrated the absence of essential differences in the characteristics of these LPS and LPS of nonrecombinant Saccharomyces cerevisiae strains, which allowed us to develop a universal complex technology of simultaneous preparation of heterologous proteins and highly active immunomodulating LPS.

Some biochemical characteristics and water exchange in human articular cartilage in osteoarthrosis.

Rearrangement of intra- and intermolecular bonds in collagen molecule, disaggregation of proteoglycans and their elimination from cartilage involved in osteoarthrosis are responsible for water accumulation and its increased mobility in cartilage.

Structural modification of collagen during nonenzymatic glycosylation in vitro.

We studied changes in collagen resistance to proteases and formation of new fluorescent compounds during in vitro nonenzymatic glycosylation. The inhibitory effects of guanidine chloride and catalase were different: guanidine chloride inhibited cross-linking in collagen molecules, while catalase inhibited the formation of chromophore-containing compounds.

Morphological changes in the liver after microwave destruction.

We studied morphological changes in the liver after local MW-destruction. Microwave radiation damaged vascular walls with the formation of extensive necrotic focus; demarcation zone appeared 24 h after exposure, encapsulation occurred after 7 days, and replacement with a fine cicatrix formed by mature connective tissue after 4 months.
