[New calcium-containing product for complex treatment of osteoporosis].

The article presents results of clinical tests of calcium-containing product--dry breakfast "Bodrost"--having in its composition a mineral part of bones of slaughter animals, on patients with menopausal and senil forms of osteoporosis. A chemical composition of the developed product is presented. Results of biochemical tests of blood and urine as well as densitometry of bones of skeleton of patients at the age from 50 to 80 years old are presented.

[X-ray densitometry and biochemical parameters of bone tissue metabolism in patients with vibration disease].

To reveal systemic and local osteoporosis, the authors studied biochemical markers of bone metabolism in vibration disease patients. The vibration disease patients appeared to have the most frequent and marked osteoporosis in peripheral bones--hands (in 90% of cases) and forearms (in 66.7%).

The role of lysosomes in the pathogenesis of unicameral bone cysts.

Unicameral bone cyst fluid possesses N-acetyl-beta-D-glucosaminidase, beta-glucuronidase, PZ-peptidase, cathepsin D, acid phosphatase, N-acetyl-beta-D galactosaminidase, and beta-galactosidase activities. The activities of lysosomal enzymes in the cyst fluid are, as a rule, higher than in the serum, whereas the total protein content is lower. The content of collagen degradation products in the cyst fluid is higher compared to the serum.

[Relation of the outcome of disk epiphysectomy in dysplastic scoliosis and the biochemical composition of the vertebral body].

Pronounced changes in the content of collagen, non-collagen proteins and the activity of a number of lysosomic enzymes have been established in the bone tissue of the vertebral bodies obtained on diskepiphysectomy in the patients with dysplastic scoliosis. Numerous correlation links between the metabolic parameters and the spinal deformation a year after diskepiphysectomy have been determined.
