Changes of heavy metal concentrations in cross-sections of human femur head.

The concentrations of 12 elements (Ni, Ma, Cr, Cd, Pb, Cu, Fe, Zn, Mg, K, Na, Ca) were determined in cross-sections of human femur heads. The highest concentrations of these elements was found in the cortical bone, and the lowest concentrations occurred in the trabecular bone, with exception of the E cross-section, in which the lowest values were found in articular cartilage. The average concentrations of Na, Ca, K, and Mg were highest in cortical bone and lowest in articular cartilage.

[Cationic equilibrium in femur capitulum at smoking and nonsmoking people].

In this paper was presented factor cationic equilibrium for lemur capitulum smoking women and men. The factor equilibrium was solved according Czarnowski model. At comparing element was calcium.

[The influence of cigarette smoking on the content metals in femur capitulum cut the two ways].

The role of smoking cigarette in contamination by Cd, Pb were investigation on the basis the femur capitulum women and men. Contributed potential parts biomechanical parameter (pressure) on the distribution of Pb and Cd in tissue osseous. The way of fragmentation of femur capitulum have great important for occurrence of Pb in tissue osseous smoking women and men in comparison to no smoking.

[Effect of organism environment upon bacteriostatic and mechanical properties of palacos R cement with antibiotic--second part].

The results of bacteriological tests of Palacos R cement with antibiotic 4 days, 7 days, 2 weeks, 3 weeks and 4 weeks after implantation in rabbit organism have been presented in this work. The results of tests of mechanical characteristics of cement with and without antibiotic samples after being kept in physiological saline for 3 to 6 weeks have also been discussed. Bacteriological tests prove that antibiotic (III generation cephalosporin) added to surgical cement retain its bacteriostatic properties.

[The effect of organism environment on bacteriostatic and mechanical properties of Palacos R cement mixed with antibiotic].

The results of bacteriological tests of Palacos R cement with antibiotic directly after its obtaining and 3 and 6 months after implantation in rabbit organism have been presented in this work. The results of tests of mechanical characteristics of cement with and without antibiotic samples after being kept in physiological saline for 3 to 6 weeks have also been presented. Bacteriological tests prove that antibiotic (III generation cephalosporin) added to surgical cement retain its bacteriostatic properties.
