THE USING OF NEW PRESERVING SOLUTION FOR THE STORAGE AND THE DEMONSTRATION OF ANATOMICAL PREPARATIONS

For storage and open demonstration of moist anatomical educational preparations and museum exhibits proposed to use a new preservative, which is an aqueous solution of 0.014-0.019% 3-iodine-2-propinilbutilcarbonate. The solution has high antiseptic activity and does not have a local irritant effect on the skin, mucous membranes of the upper respiratory tract and oral cavity, as well as on the conjunctiva of the eyes. The proposed preservative is non-toxic and environmentally safety. Long-term storage and use of anatomical preparations in the proposed preservative does not cause any damaging changes, violations of their shape, structure and color. The method is patented by the Russian Patent Agency.

AbstractA novel process for preparing scorodite particles with a diameter of approximately 20 µm from Fe(II) and As(V) in aqueous solution has been developed by DOWA Metals and Mining. In the present study, the dissolution characteristics of iron and arsenic from the scorodite particles synthesized by this process have been investigated under different conditions. The results show that the concentration of arsenic dissolved from the particles in aqueous solution is very low, but it has a complicated dependence on the temperature and pH of the solution. Transmission electron microscopy (TEM) with an energy dispersive X-ray spectrometer (EDS) was used to analyze the morphology, structure, and composition of the scorodite particles. The results indicate that the scorodite particles exhibit a nearly octahedral shape with planes composed of almost (111) planes in the orthorhombic structure. The concentration of iron at the surface of the particles is higher than that of iron inside of the particles. This characteristic morphology, along with the minimal surface defects of the scorodite particles, is considered to be responsible for the low dissolution of arsenic from the particles in aqueous solution. Atmospheric temperature and solution conditions were also found to be important for the safe, long-term storage of arsenic using scorodite particles.

Aim.To study the level of specific antibodies of different isotypes to the antigens of Staphylococcus aureus and Klebsiella рneumoniae in the serum, saliva and nazal secret and the concentration of IgA,sIgA,IgG in saliva from frequently and long-term ill children in nasal-oral administration of Immunovac VP-4.Materials and methods.Specific antibodies to S. aureus and K.pneumoniae, contained in saliva, nasal, and serum were determined by the method of enzyme immunoassay. Concentrations of immunoglobulins of classes G, A and sА in saliva were determined by radial immunodiffusion using a commercial kit produced by the NPC «Medical immunology».Results. The high level of specific antibodies contained in the serum and nasal secretions, the level of antibodies in saliva is negligible. The serum is dominated by IgG-isotype antibodies, saliva and nasal secret — antibodies of IgA-isotope. After the introduction of Immunovac VP-4 there was a statistically significant increase in the level of specific antibacterial antibodies in serum, saliva and nasal secret, and increasing levels of IgG and sIgA in saliva.Conclusion. Obtained data demonstratet that the nasal-oral scheme of administration of Immunovac VP-4 frequently and long-term ill children allowed to increase the level of specific antibodies in serum, saliva and nasal secret to bacterial antigens that are part of the vaccine and to normalize the local synthesis of IgG and sIgA, which play a major role in the protection of the respiratory tract and mucous membranes of the upper respiratory tract.

ABSTRACTThe applicability of a process, originally developed to immobilize a chloride-rich intermediate level waste (ILW) arising from the pyrochemical reprocessing of plutonium, to alternative ILW waste-streams containing a large variety of cations, present as oxides together with KCl and CaF2, has been investigated. Non-radioactive studies, using simulated wastes containing hafnium and samarium as surrogates for the actinides, have been performed to establish the optimum processing parameters for the manufacture of wasteforms suitable for long-term storage/disposal. It has been demonstrated that the wastes can be immobilized by calcining with either Ca3(PO4)2 or CaHPO4 as the host. In excess of 97.5 % of the chloride present in calcined wastes, containing up to 3.2 wt% halides as a mixture of F- and Cl-, is immobilized when using this process. Whereas in the original calcined waste, the Cl- (about 12 wt%) was immobilized as chlorapatite, Ca5(PO4)3Cl, and spodiosite, Ca2(PO4)Cl, in these current wastes fluorapatite is the predominant halide containing phase. Conversion of the immobilized waste powder into a monolithic wasteform was achieved by sintering the powder with the addition of a sodium aluminium phosphate based glass. Both the calcined powder and the sintered monolithic wasteforms showed excellent durability in aqueous solution.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
