Osteoplastic fixation of the spine

The combined anterolateral osteoplastic fixation of the spine was carried out on 17 cases out of 73 operated upon for pathological spinal changes of various etiology. The tibial crest rigid homograft and the rib autograft on vasoneuromuscular feeding pedicle were used. Such a combination of bone grafts possessing different mechanic and osteogenic properties permitted to obtain a reliable fixation of the spine for all the period necessary for anatomic and functional reconstruction of the grafts.     

The effect of Opisthorchis on the manifestations of herpesvirus type 2 in an experiment and their possible participation in the mechanism of the occurrence of primary liver cancer

In a 4 month study, a group of 16 patients with stable renal graft function receiving triple immunosuppressive therapy including cyclosporin A (Cy A) were investigated for the levels of calcium, magnesium and zinc in erythrocytes. The patients were randomized to be converted to the new microemulsion formulation (Sandimmun Neoral) in a 1:1 fashion (n = 8) or to continue with the classical formulation (Sandimmun) (n = 8). The concentrations of creatinine, phosphate, alkaline phosphatase activity, calcium, magnesium and zinc were measured twice a month in blood plasma. The concentration of calcium, magnesium and zinc in erythrocytes was also measured. The concentration of magnesium in blood plasma and erythrocytes during the study showed no deviation from normal values. The level of zinc in erythrocytes was almost twice as high as in normal healthy controls and was not dependent on Cy A formulation. Calcium content in erythrocytes of patients receiving Sandimmun was 27.6% higher than in healthy persons. Conversion of the patients to Sandimmun Neoral normalized the calcium concentration in erythrocytes and caused a transient increase of calcium levels in blood plasma.     

The course and outcome of viral hepatitis B in drug-addicted patients

In this paper, characterization is given of clinical and biochemical features of VH B course against the background of narcomania. Recordable in such patient populations are high percentage of delta hepatitis (14.2%), unusual severity of the intoxication syndrome, protracted course with exacerbations (12.2%) and recurrences (8%), outcome being a chronic hepatitis (14.2%), slower normalization of biochemical indicators, persistently low ratio of AIAT activity in diluted and whole blood sera. The persistence of viral markers in drug addicts discharged from the hospital (68%) is fraught with danger of spreading viral hepatitis of prophylactic measures are not strictly observed.     

Role of cadherins in the transendothelial migration of melanoma cells in culture

This study examines the nature and extent of the relationship between stress levels and intentions to participate in a worksite smoking cessation program among male current smokers (n = 220) employed in an automobile manufacturing plant. A plantwide survey was conducted which measured job stress, nonjob stress, smoking behavior, and intent to participate. The results of polychotomous logistic regressions suggest that among the current smokers in this plant, job and nonjob stress were positively associated with workers' intentions to participate in a worksite smoking cessation program. Thus, contrary to the popular notion that stress diminishes the motivation to quit, employees under high levels of stress may be most receptive to educational interventions intended to persuade smokers to commit to quitting.     

The use of laser and phototherapy in the comprehensive treatment of malignant tumors and leukemia in children

The report deals with the development of procedures, evaluation of laser application and prevention of complications involved in intensive chemoradiation therapy of neoplasms of hemopoietic and lymphoid tissue in childhood. The clinical data on 548 patients, aged 2 months-15 years, with leukemia and solid tumor were evaluated. Laser application for treatment of different complications of chemoradiation therapy of pediatric leukemia proved a valuable innovation. It had a pronounced antiinflammatory and analgetic effect, promoted tissue regeneration processes and cut down the duration of complication treatment drastically.
