Experience in organizing surgical care during the combat operations in the Chechen Republic

In the article the final analysis of organization of surgical care during the local military conflict in northern Caucasus was presented. The real possibilities of different medical units such as single medical company and medical squadron of special assignment was described. Also concrete contents of emergency specialized surgical care and its role in improvement of outcomes in patients with combined combat injuries was reflected. Mortality in this patients was decreased from 25.2 to 12.8%. The defects of surgical care were analyzed and the main ways of improvement of surgical care in local military conflict were presented. In the result of using the principle of moving the medical care closer to the wounded in the whole system of consecutive care the mortality was decreased up to 1.3%.     

Study of antiinfectious potential of recombinant tumor necrosis factor-alpha

46 patients with coronary heart disease with hypercholesterolemia were exposed to therapeutic plasmapheresis (TP) in combination with alpha-tocopherol treatment (AT). The results of 3-month follow-up with assessment of the clinical status, lipid spectrum, lipid peroxidation, concentration of ceruloplasmin indicated high hypolipidemic effectiveness of TP 2-3 weeks after the treatment as shown by inhibition of lipid peroxidation and antioxidant system. The addition of AT prolonged the hypolipidemic effect of TP, promoted optimization of plasma antioxidant potential (a rise in HDL, stabilization of ceruloplasmin levels).     

Functional morphology of nucleolus organizer regions of chromosomes and nucleoli in human multiple myeloma cell lines. I. Variation of the morphology and silver staining of nucleolus organizer regions of chromosomes in RMPI 8226 and U 266 cell lines with different level of differentiation of during 7 days after cell passage

The morphology and Ag-staining of nucleoli in human multiple myeloma cell lines RPMI 8226 and U 266, distinguished from each other in the differentiation degree, were quantitatively studied, and the production of immunoglobulins or their fragments by the line cells was evaluated throughout 7 days after cell seeding. The less differentiated cell line RPMI 8226 and the high differentiated cell line U 266 were revealed to differ in both the initial level of immunoglobulin production and dynamics of immunoglobulin accumulation in culture medium. The total number of Ag-stained nucleolar-organizer regions (AgNORs) per nucleus in cells RPMI 8226 was significantly higher than in cells U 266 in all times after seeding of the cells. In both cell lines changes in the quantity and shape of nucleoli and also in the total number of AgNORs per nucleus and pattern of AgNORs distribution within nucleoli correlated with the cell cycle phase. Relationships between morphofunctional changes in nucleoli and the differentiation degree and proliferative activity of the cells, and also between the number of Ag-positive nucleolar-organizing metaphase chromosomes and the functional activity of interphase AgNORs are discussed.     

Evaluation of the stability of parameters of direct radiographic devices

AIM: To study efficacy and tolerance of cardioselective beta-adrenoblocker lokren (betaxolol) in elderly patients with mild and moderate hypertension. MATERIALS AND METHODS: 25 elderly (mean age 70.2 +/- 1.43 years) hypertensive patients received lokren (a single dose of 10 mg daily for 3 months). The examination comprised routine tests, ECG, rheovasography of the ankle, REG of vertebral and carotid arteries, measurements of ejection fraction, total peripheral vascular resistance, myocardial mass, platelet aggregation, external respiration function, blood glucose, total cholesterol, triglycerides, beta-lipoprotein. RESULTS: The treatment produced a significant reduction in systolic (by 32.1% and 32.7% in position, respectively) and diastolic pressure (by 14.2 and 11.8%, respectively). Thickness of the posterior wall of the left ventricular myocardium decreased by 7.7%, ejection fraction by 2.9%, total peripheral vascular resistance went up by 11.5%. Spontaneous and induced platelet aggregation declined. There was an insignificant rise in the levels of cholesterol, beta-lipoproteins, triglycerides, glucose. REG and rheovasography data tended to a small rise. External respiration remained unchanged. The need in nitroglycerin reduced by 58%. CONCLUSION: Lokren (betaxolol) can be recommended as effective hypotensive monotherapy of mild and moderate blood hypertension in elderly patients.     

Experimental-morphological and clinical basis of preventive methods for the intraoperative complications of the amputation of the lower extremity at the thigh level]

Using total quality management principles within a shared governance framework, this case study discusses how to design and implement a plan to achieve independent nursing practice when an employee has unique needs. This experience demonstrates the importance of looking at root causes, separating ability and compliance issues, using all available resources creatively, and planning for success.     

Clinical manifestations and treatment of intestinal dysbacteriosis in patients with Flexner's dysentery

Flexner's dysentery is often accompanied with intestinal dysbacteriosis. Disbiotic changes in the intestine contribute to specific shigella endotoxins entering blood flow thus prolonging clinical symptoms of the underlying disease. Administration of bacterial biological preparations (bifidumbacterin forte, lactobacterin) relieves specific endotoxemia, reduces the duration of the disease and has an immunomodulating action.     

Functional activity of peripheral blood neutrophils of rats during combined effects of hypoxia, hypercapnia and cooling

Functional activity of neutrophilic leukocytes was studied in blood of rats immediately following single and repeated gradual increase in carbon dioxide and decrease in oxygen concentrations with the ambient temperature at 2 to 3 degrees C. Phagocytic activity was shown to alter as the number of phagocytic neutrophilic granulocytes, absorptivity or the phagocytic index, and the coefficient of phagocytosis completeness were elevated and levels of oxygen-dependent and oxygen-independent metabolism were reduced.     

The capacity to distinguish short durations of time intervals in children and adults]

Two groups of children (5-6-year-old and 7-8-year-old) were presented with pairs of sound signals of the same or different durations. Sound signal durations in pairs could be 1.0, 1.2, 1.5, and 2.0 sec. The children had to detect the difference between the sounds in a pair. The obtained data were compared to the analogous results shown by the 18-39-year-old subjects. It was found out that the ability to discriminate intervals of short duration substantially improved with age. This phenomenon in presumably connected with perfection of the short-term memory. Independently of the subject's age, the order of presentation of signals in a pair influences the ability to discriminate between their durations.
