Barkáts N. Palmaris longus, a muscle that lost its function, or not? A pilot study
Abstract. The palmaris longus muscle is one of the most variable muscles in human body. Its most common anatomic variation is the complete agenesis of the muscle. The palmaris longus is considered to be a phylogenetically redundant muscle which lost its function. This led to great importance of the muscle in plastic and reconstructive surgery, since the palmaris longus can be extracted from the forearm without any complications, and can be used as a donor muscle. The general point of view is that the presence or absence palmaris longus has no effect on the functioning of the forearm. This pilot study aims to assess the grip strength in people who have unilateral agenesis of the muscle, thus establish whether it has any influence on the grip strength. According to the results there is a great deviation from the expected results in patients who had unilateral agenesis of the muscle.
Keywords: palmaris longus muscle, agenesis, grip strength, Hungarian population

Gregirchak N.N., Lych I.V. Research on cancer vaccines on cellular immunity of mice with Lewis lung carcinoma
Abstract. Antitumor activity of xenogenic and homologous vaccines prepared with the use of protein containing metabolites of Bacillus subtilis B-7025 with molecular weight of 18.5 and 70 kDa were studied on Lewis lung carcinoma model. The relation of tumor growth dynamics in mice that received vaccines injections with cytotoxic activity of lymphocytes and macrophages was revealed. Those results can be used for further studies of the vaccine impact on humoral immunity section and for potential production of cancer vaccines based on these glycoproteins and chicken embryonic proteins.

Lych I.V., Voloshyna I.M. Immunomodulatory properties of the interferoninducing molecular complex
Abstract. In in vitro experiments the MC was suggested to perfect the activity of monocyte-macrophageal system via the increase of phagocytosis percent (by 2,5 – 3,5 times), phagocyte number (by 2 times); the MC also accelerates the oxygen-dependent cell metabolism. The MC demonstrates also a dose-dependent modulatory effect on indices of cytolytic activity of natural killer cells: low and moderate MC concentrations inhibit this activity, while high concentration stimulates it. The MC was also proved to have influence on peripheral blood lymphocytes at the receptor expression level. So MC can be attributed to a potential immunomodulator with different types of effects on the immune system

Balichieva D.V. Medicobiological criteria of unfavorable action of physical factors on the genital system
Abstract. The analysis of biological criteria of unfavorable action of vibration on the genital system of masculine and female organ- isms is given in this work. The complex of hygienically, sociological, clinical and experimental researches is conducted in the article. The hygienical estimation of terms of labour of workings vibrodangerous professions is given by complex estimation of labour ac- tivity taking into account all factors of production environment. The integral index of complex estimation of factors of production as a statistical mark of degree harmfulness of every factor (V+sn) is expected, and the sum of balls on all factors characterized the de- gree of occupational take of every professional group. It is set that influence of vibration of workplaces on a genital function will mediate as both female and masculine organism. The cri- teria of negative factor on a female organism is frequency of violations of menstrual function, spontaneous abortions, stillborn, rejec- tion in the anthropometric indexes of new-born, diseases of children in early age; a masculine organism is oppressing of sexual func- tion, reliable increase of frequency of spontaneous abortions of their wives, not having contacts with a vibration. Correlated and regressive analysis of morbidity with temporal loss of ability to work depending on the degree of harmfulness of complex of factors of production allowed to get the row of coefficients of biological activity. So size of increase of morbidity on a 1 mark of degree of harmfulness (integral index of degree of harmfulness of all factors) on the indexes of being ill persons for women higher, than for men in 4,5 time, on the cases of disease is 4,3 time, on the days of disability are 2,2 time and on the losses of days of disability in 2,1 time. Thus biological equivalent of sex of women as a risk factor estimated from 2 to to 5 marks of degree of harm- fulness. An additive effect is set on the indexes of frequency of spontaneous abortions, stillborn in cases when both spouses work in the con- ditions of influence of vibration. At the same time the vibrodangerous profession of spouse almost also tells as well as his harmful habits: smoking and abuse of alcohol. All of it allowed to expect the coefficients of biological efficiency of vibration at affecting genital function of workers. So, the vibrodangerous profession of the married couples promotes a risk for posterity on the indexes of mass new-born, to frequency of stillborn, to the infantile death rate to 4 times, and also at combination with harmful habits (smoking, use of alcohol) to 8 times.

Brem V.V., Kozhukhar V.Ya, Dmitrenko I.V., Buga S.P. Technological features of production of moisture fluxes
Abstract. The existing technology of manufacturing fluxes leads to the formation of various crystalline oxide phases which are chemically active towards to the moisture of air. When storing fluxes absorb moisture of air and as a consequence hydrate with water content up to 0.5 mass. %. To eliminate this drawback the method of increase of water-resistance of fluoride-oxide fluxes in which technologically combined the processes of carbonization and granulation was proposed. Conducted thermodynamic calculation of the method and the analysis of the obtained thermodynamic data allowed to conclude that the holding of the carbonization process (РСО2 = 0,101325 МПа) in the investigated temperature range is possible not for all considered reactions. Optimal conditions for carbonization of multicomponent production fluxes must be adapted to the diversity of their actual phase composition. Conducted industrial tests of the method of obtaining of fluxes, providing the ncrease of their water-resistance with open storage on the air at the Nikopol ferroalloys plant. To implement the method was roposed a new variant of layout of the pipe-collector and basket-receiver in the system of technological equipment. This enabled to combine the process of carbonization with dry granulation. Tests have shown the efficiency of a method in application to the manufacture of luoride-oxide fluxes of increased water-resistance.

Borkach E.I., Ivanitsky V.P., Kovtunenko V.S. Order and disorder in the aggregate states of the substance
Abstract. It is justified that in the material science the term ‘disorder’ must have the only meaning that the microscopic state of the system of many particles is assigned by a set of random quantities calculated on the basis of the probabilistic laws. At that point we must take the geometrical (topological) parameters of the ideal spatial linkage of the atoms as basis of division of the solids into the crystalline and amorphous ones. We also suggest calling the ideal structurally ordered substances the substances, in which fully determinated functional dependence between the topological parameters of atomic network is observed. This stipulates the existence of determinated short-range order, which, by virtue of their determinated character, ensure the formation of large-range order as well. We shall call the ideal totally structurally disordered systems the systems, in which there is no correlation in the location of the struc- tural particles in the space. We also suggest calling the structurally disordered (unordered) substances the substances, in which only the probabilistic correlation relation between the topological parameters of atomic network is observed. This stipulates the existence of the correlation short-range order and correlation medium-range order of the ideal atomic network, which, by virtue of their probabilistic nature, result in the loss of large-range order. Besides the topologic ordering and disordering, a number of other types of ordering and disordering are realized in the substances. Certain of them are inherent in the crystals only, other – in the amorphous substances and liquids only, some of them are typical for any condensed medium.
