The size, shape and surface morphology of human erythrocytes (RBC) were examined by scanning electron microscopy (SEM), of the fixed material directly and by transmission electron microscopy (TEM) of surface replicas to compare the relative merits of these two observational procedures for this type specimen.A sample of human blood was fixed in glutaraldehyde and washed in distilled water by centrifugation. The washed RBC's were spread on freshly cleaved mica and on aluminum coated microscope slides and then air dried at room temperature. The SEM specimens were rotary coated with 150Å of 60:40- gold:palladium alloy in a vacuum evaporator using a new combination spinning and tilting device. The TEM specimens were preshadowed with platinum and then rotary coated with carbon in the same device. After stripping the RBC-Pt-C composite film, the RBC's were dissolved in 2.5N HNO3 followed by 0.2N NaOH leaving the preshadowed surface replicas showing positive topography.

Russian economy has reached the low level of inflation, but economic growth has not accelerated. Moreover, according to official forecasts, in the following years it will still be low. The article concludes that domestic demand, which is one of the main factors of growth, is significantly constrained by monetary, budgetary and fiscal spheres. The situation in the Russian economy is still hampered by the decline of the world economic growth. The prospects of financial markets are highly uncertain. This increases the possibility of crisis in the world. Leading countries widely use non-traditional measures to support their economies in the similar environment. In the world economy as well as in Russia a principally new combination of factors has emerged, which create specific features of economic growth. It requires special set of measures to stimulate such growth. The article proves that Russian regulators have large unused potential to stimulate growth. It includes monetization, long-money creation, budget and tax stimuli. It is important that the instruments, which will be used, should be based on domestic mechanisms. This will strengthen financial basis of the economy and may encourage economic growth. Some specific suggestions as to their use are made.

This paper objectives are to; (i) identification of risky slopes (within 4 Provinces in Sumatra including Provinces of Riau, West Sumatra, Jambi and South Sumatra encompassing 840 kms of the “Jalan Lintas Sumatra” highway) based on Rockfall Hazard Rating Systems (RHRS) method; (ii) developing alternatives to stabilize slope hazards, and (iii) selecting appropriate slopes stabilization techniques based on both proactive approach and value engineering one. Based on the Rockfall Hazard Rating Systems (RHRS) method, it was identified 109 steep slopes prone to failure within this highway section. Approximately, 15 slopes were identified as potential high-risk slopes (RHRS scores were calculated >200 points). Based on the proactive approach, seven riskiest slopes ware identified. The preferred stabilization alternatives to remedy most of these slopes are suggested as follow; either (i) a combination of retaining wall and drainage, or (ii) gabion structure and drainage. However, different approaches may yield different results, there are at least 2 main consideration in prioritizing slope stabilization; (i) based on the riskiest slopes, and(ii) the least expensive stabilization alternatives.

Relevance. Empirical treatment of vaginitis is indicated due to its polymicrobial etiology and limited microbiological analysis. The aim of the study was to study the combination of ornidazoleneomycinprednisoloneeconazole (ONPE, Elzhina) as a first-line drug for local treatment of patients with various forms of non-specific vaginitis. Materials and methods. The study included 55 non-pregnant women aged 18 to 50 years (381.5 years) who had clinical and laboratory signs of acute vaginitis. Results. All patients at the initial treatment complained of pathological discharge, 47 (85.5%) noted itching, burning, pain in the genital area of various degrees of severity, 17 (30.9%) discomfort when urinating, 9 (16.4%) unpleasant smell, 8 (14.5%) dyspareunia, 4 (2.2%) complained of sensations of a foreign body in the vagina. The clinical and laboratory effectiveness of treatment was 89.1% (49). In 6 (10.9%) patients, clinical improvement was noted, with the remaining laboratory signs of aerobic vaginitis. Conclusion. The new combination of ornidazoleneomycinprednisoloneeconazole (ONPE, Elzhina ) has a good efficacy and safety profile and can be used to initiate empirical treatment of non-specific inflammatory diseases of the lower genital tract.
