[The comparative characteristics of cranioplasty methods using biological materials]. / Sravnitel'naia kharakteristika sposobov kranioplastiki biologicheskimi materialami.

Comparative results were obtained in the experiments conducted on dogs in cranioplasty using allogenic bones, one-piece or small-fragmentized brephoxenotransplants. It was found out that allogenic bones and brephoxenotransplants, when conserved in the solution of 0.2% of formaline and 0.1% of gl. aldehyde, were a perfect material for cranioplasty. These materials ensure a reparative osteogenesis in the recipient's organism after grafting. The process in small-fragmentized brephoxenotransplants is more active and ensures the bone recuperation of the vault of skull in 1.5 years.

Concentrations of phosphate esters in blood of patients with vertebral osteochondrosis and activities of enzymes involved in thiamine metabolism have been investigated. The pathological processes were characterized by a decrease in content of thiamine triphosphate while concentration of coenzyme, thiamine diphosphate, was relatively constant. The enzymes involved in the initial and final steps of biosynthesis and degradation of thiamine phosphorylated derivatives play the main role in maintaining vitamin B1 metabolic homeostasis.
