Biocompatibility of polyhydroxybutyrate microspheres: In vitro and in vivo evaluation / E. I. Shishatskaya [et al.] // Journal of Materials Science: Materials in Medicine. - 2008. - Vol. 19, Is. 6. - P2493-2502, DOI 10.1007/s10856-007-3345-6 . - ISSN 0957-4530

Аннотация: Microspheres have been prepared from the resorbable linear polyester of ?-hydroxybutyric acid (polyhydroxybutyrate, PHB) by the solvent evaporation technique and investigated in vitro and in vivo. Biocompatibility of the microspheres has been proved in tests in the culture of mouse fibroblast cell line NIH 3T3 and in experiments on intramuscular implantation of the microspheres to Wistar rats for 3 months. Tissue response to the implantation of polymeric microspheres has been found to consist in a mild inflammatory reaction, pronounced macrophage infiltration that increases over time, involving mono- and poly-nuclear foreign body giant cells that resorb the polymeric matrix. No fibrous capsules were formed around polymeric microparticles; neither necrosis nor any other adverse morphological changes and tissue transformation in response to the implantation of the PHB microparticles were recorded. The results of the study suggest that polyhydroxybutyrate is a good candidate for fabricating prolonged-action drugs in the form of microparticles intended for intramuscular injection.

Аннотация: Samples of a hybrid composite of polyhydroxybutyrate (PHB), a biodegradable polyester, and hydroxyapatite (HA), with different PHB/HA ratios, have been prepared using mechanical-physical method. Electron microscopy, X-ray structure analysis and differential thermal analysis have been used to investigate the structure and physicochemical properties of the composite, depending on the PHB/HA ratio. The properties of the surface of the HA-loaded composite are significantly different from those of the pure polymer. As the HA percentage in the composite increases, free interface energy, the cohesive force, i.e., the strength of the adhesive bond between the composite surface and the water phase, and surface wettability increase. The HA percentage of the composite does not influence its melting temperature, but affects the temperature for the onset of decomposition: as the HA content increases from 0 to 10% (w/w), Td decreases from 260В°C to 225В°C. The degree of crystallinity of PHB/HA increases from 77% to 89% with an increase in the HA fraction from 10% to 50%. Functional properties of the composites have been investigated in vitro and in vivo. The best parameters of growth and differentiation of murine marrow osteoblasts are registered on PHB/HA samples containing 10% and 20% HA. In ectopic bone formation assay it has been proven that the hybrid PHB/HA composites can function as scaffolds and that bone tissue develops on their surface and in pores. В© VSP 2006.

Аннотация: Chronic experiments on mature Wistar rats studied the biological properties of suture threads from two types of polyoxyalkanoates (POA), such as polyoxybutyrate (POB) and the copolymer of POB and polyoxyvalerate (POV) (POB/POV) as compared to the conventional surgical material (silk and catgut). The physiological and biochemical parameters that reflect the status of the animals, including their behavior, height and development, the weight of the body and viscera, the morphology of peripheral blood, the biochemical parameters of blood, the activity of some enzymes, as well as histological findings of the viscera, and lymphoid tissue responses were assessed. POA was found to produce no negative effect on the physiological, biochemical, and functional characteristics of the animals irrespective of the duration of contact with the internal medium of the body and of the chemical composition of a material.

Аннотация: Specimens of 14C-labeled polymer of 3-hydroxybutyric acid, P(3-HB), with different initial molecular weights, were used to prepare microparticles, whose morphology was not influenced by the M w of the polymer. During the particle preparation process, P(3-HB) molecular weight decreased by 15-20%. Sterile microparticles (mean diameter 2.4 ?m) were injected into the tail veins of Wistar rats (5 mg/rat). The effects of the particles administered to rats were studied based on the general response of animals and local response of internal organ tissues and blood morphology; no adverse effects on growth and development of the animals or unfavorable changes in the structure of the tissues of internal organs were observed. Measurements of radioactivity in tissues showed that 14C concentrations are different in different organs, changing during the course of the experiment. The main targets for 14C-labeled microparticles were tissues of the liver, spleen, and kidneys. Comparison of radioactivity levels and residual contents of high-molecular-weight matrix in tissues suggested that the most rapid metabolism and degradation of P(3-HB) occurred in the liver and spleen. Gel-permeation chromatography showed that at 3 h after the microparticles were injected into the bloodstream, polymer degradation started in all examined organs, except the lungs; at 12 weeks, the M w of the polymer matrix was as low as 20-30% of its initial value. The presence of high-molecular-weight (undegraded) polymer in the tissues at 12 weeks after administration of the particles suggests that P(3-HB) is degraded in tissues of internal organs slowly and, hence, P(3-HB)-based microparticles can be used as sustained-release drug-delivery systems.

Аннотация: The paper presents the results of biomedical investigations of sutures made of polyhydroxyalkanoates (PHAs) of two types (poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-poly-3-hydroxyvalerate (PHB/PHV)), synthesized by the bacteria Ralstonia eutropha B 5786 in the experiment on test animals in vivo, in comparison with silk and catgut sutures. PHB and PHB/PHV (PHBV) implants produced no adverse effect on physiological, biochemical and functional parameters of the animals during the post-surgery period. The tested PHA sutures featured the necessary strength throughout the healing period of the muscle-fascial cuts. The reaction of tissues to the implantation of PHB and PHB/PHV fibers fitted into the usual scheme characteristic of the wound process and of the reaction to a foreign-body invasion. This reaction and the reaction of tissues to silk had the similar nature and period of inflammation, but it was much less pronounced than the reaction to catgut. The tissue response to the implantation of PHAs consisted in a short-duration (up to 2 weeks) post-traumatic inflammation and the formation of a fibrous capsule less than 200 ?m thick during weeks 4-8, which in 4-6 months was reduced to 40-60 ?m in the course of reverse development. There were no adverse changes, such as suppurative inflammation, necrosis, calcification, and malignization of the cicatrice, at the site of implantation of PHA filaments, unlike in the cases with silk and catgut. In the case of PHA implantation there was a typical prolonged (throughout the post-surgery monitoring period) pronounced macrophagal stage with a large number of macrophages present. The macrophages were of the phagocytic type and multinucleate giant foreign cells, with a high activity of acid phosphomonoesterase that correlated with the activity of the enzyme in blood. Throughout the period of monitoring no differences in the tissue response to the implantation of the polymer filaments of two PHA types were recorded. В© 2003 Elsevier Science B.V.

Tritium in surface waters of the Yenisei River basin / A. Y. Bolsunovsky, L. G. Bondareva // Journal of Environmental Radioactivity. - 2003. - Vol. 66, Is. 3. - P285-294, DOI 10.1016/S0265-931X(02)00132-7 . - ISSN 0265-931X

Аннотация: This paper reports an investigation of the tritium content in the surface waters of the Yenisei River basin near the Mining and Chemical Combine (MCC). In 2001 the maximum tritium concentration in the Yenisei River did not exceed 4 В± 1 Bq l-1, which is consistent with the data of 1998-99. However, it has been found that there are surface waters containing enhanced tritium as compared with the background values for the Yenisei River. For instance, in the Ploskii Stream and the Shumikha River the maximum tritium concentrations amount to 168 and 81 Bq l-1, respectively. The source of tritium in these surface waters is the last operating reactor at the MCC, which still uses the Yenisei water as coolant. In water and sediment samples of the Bolshaya Tel River (a tributary of the Yenisei River) the tritium content turned out to be at least 10 times higher than the background values for the Yenisei River. The measurements conducted at the RPA RADON (Moscow) revealed not only tritium but also the artificial radionuclide 14C in the Bolshaya Tel samples. The data obtained suggest that the Bolshaya Tel River receives the major part of tritium from sediments rather than from the water catchment area. This allows the conclusion that there is water exchange between the surface waters and the radioactively contaminated underground horizons of the "Severny" testing site. В© 2002 Elsevier Science Ltd.

Аннотация: We studied soil-like substrate (SLS) as a potential candidate for plant cultivation in bioregenerative life support systems (BLSS). The SLS was obtained by successive conversion of wheat straw by oyster mushrooms and worms. Mature SLS contained 9.5% humic acids and 4.9% fulvic acids. First, it was shown that wheat, bean and cucumber yields as well as radish yields when cultivated on mature SLS were comparable to yields obtained on a neutral substrate (expanded clay aggregate) under hydroponics. Second, the possibility of increasing wheat and radish yields on the SLS was assessed at three levels of light intensity: 690, 920 and 1150 ?mol m-2 s-1 of photosynthetically active radiation (PAR). The highest wheat yield was obtained at 920 ?mol m-2 s-1, while radish yield increased steadily with increasing light intensity. Third, long-term SLS fertility was tested in a BLSS model with mineral and organic matter recycling. Eight cycles of wheat and 13 cycles of radish cultivation were carried out on the SLS in the experimental system. Correlation coefficients between SLS nitrogen content and total wheat biomass and grain yield were 0.92 and 0.97, respectively, and correlation coefficients between nitrogen content and total radish biomass and edible root yield were 0.88 and 0.87, respectively. Changes in hormone content (auxins, gibberellins, cytokinins and abscisic acid) in the SLS during matter recycling did not reduce plant productivity. Quantitative and species compositions of the SLS and irrigation water microflora were also investigated. Microbial community analysis of the SLS showed bacteria from Bacillus, Pseudomonas, Proteus, Nocardia, Mycobacterium, Arthrobacter and Enterobacter genera, and fungi from Trichoderma, Penicillium, Fusarium, Aspergillus, Mucor, Botrytis, and Cladosporium genera.

Аннотация: The inhibition of bacterial luminescence has been used in testing industrial enterprises sewage. The toxicity of the sewage is less than the total toxicity of separate components due to neutralization of quinone products of polyphenol oxidation in the reactions with the other phenol components of sewage. Toxicity increase is due to their influence on the cell membrane. Studies of cell ultrastructure confirm this fact. The studied mechanism of the complex effect allowed a more accurate forecast of the ecological situation during the discharge of phenol compounds and metals. It also showed the necessity of taking into account the complex effect of sewage components on contaminant discharge into water reservoirs.

Аннотация: The laboratory testing of bottom sediments (BSs) from the Yenisei River containing different concentrations of technogenic radionuclides, heavy metals, and biogenic elements (N and P) based on aquatic such plants as Elodea canadensis (Canadian waterweed) and Myriophyllum spicatum (Eurasian watermilfoil) has revealed a higher sensitivity of roots to the general quality of BSs than shoots: shoot length (9%) < root length (11%) < root number (15%) in M. spicatum; shoot length (22%) < root length (42%) < root number (44%) in E. canadensis. In contrast to M. spicatum, the growth parameters of roots and shoots in E. canadensis have differed in a significant statistical manner between most BS samples. A reverse correlation has been found between the increase in shoot length and the activity of technogenic radionuclides in BSs, which is mostly significant in E. canadensis (r (2) = 0.90-0.95, p = 0.05). Since the growth of shoots and roots in E. canadensis has turned out to be more sensitive to changes in the quality of BSs than that in M. spicatum, E. canadensis can be considered more prospective for biotesting BSs.

Аннотация: Various chronic inflammatory and necrotic processes in the liver parenchyma are accompanied by pathological morphofunctional changes, which are associated with hepatocyte death and hyperplasia of the connective tissue. Regeneration of the liver parenchyma should include not only prevention of fibrosis, but also stimulation of hepatocyte prolifearation. The adrenoceptor agonist dobutamine stimulated proliferative activity of cultured hepatocytes and prevented the development of postintoxication liver cirrhosis in mice produced by chronic poisoning with CCl4.

Mineralization of wastes of human vital activity and plants to be used in a life support system [Text] / Y. A. Kudenko, I. V. Gribovskaya, R. A. Pavlenko // Acta Astronaut. - 1997. - Vol. 41, Is. 3. - P. 193-196, DOI 10.1016/S0094-5765(97)00215-4. - Cited References: 8 . - ISSN 0094-5765

Аннотация: Available methods for mineralizing wastes of human activity and inedible biomass of plants used in this country and abroad are divided into two types: dry mineralization at high temperatures up to 1270 K with subsequent partial dissolution of the ash and the other-wet oxidation by acids. In this case mineralization is performed at a temperature of 470-460 K and a pressure of 220-270 atmospheres in pure oxygen with the output of mineral solution and dissoluble sediments in the form of scale. The drawback of the first method is the formation of dioxins, CO, SO2, NO2 and other toxic compounds. The latter method is too sophisticated and is presently confined to bench testing. The here proposed method to mineralize the wastes is in mid-position between the thermal and physical chemical methods. At a temperature of 89-90 degrees C the mixture was exposed to a controlled electromagnetic field at normal atmospheric pressure. The method merits simplicity, reliability, produces no dissoluble sediment or emissions noxious for human and plants. The basic difference from the above said methods is to employ as an oxidizer atomic oxygen, its active forms including OH-radicals with hydrogen peroxide as the sourer. Hydrogen peroxide can be produced with electric power from water inside the Life Support System (LSS). (C) 1998 Elsevier Science Ltd. All rights reserved.
