Transfer of americium-241 from food and water to organs and tissues of the crucian carp * / T. Zotina [et al.] // Radioprotection. - 2011. - Vol. 46, Is. 6 SUPPL. - S69-S73, DOI 10.1051/radiopro/20116648s . - ISSN 0033-8451
Аннотация: The transfer of transuranium element americium-241 (241Am) from food and water to organs and tissues of freshwater fish (Carassius auratus gibelio, crucian carp) has been investigated in laboratory experiments. The fishes were fed with homogenized biomass of submerged macrophytes labeled with 241Am, through catheter. For the first two days after force-feeding, fishes excreted up to 80% of ingested americium, for four days - 98%. 241Am was registered in internal organs and tissues that had no direct contact with americium (liver, bones, muscles) as early as two days after the feeding and after eight days, when the digestive tract was depurated. Among internal organs, the highest activity concentration was recorded in the liver (up to 427 Bq/kg). Activity concentration in bones (19-31 Bq/kg) was several times higher than in muscles, indicating the affinity of americium to bone tissue. Assimilation of 241Am in organs and tissues of crucian carp from water occurred mainly via the digestive tract too. В© 2011 EDP Sciences.

Аннотация: Microparticles obtained by using 14C-labeled resorbable hydroxyaminobutyric acid polymer were injected into the caudal vein of laboratory animals without negative aftereffects for their growth and development and without changes in the macro- and microstructure of organs and tissues. The distribution of microparticles in the viscera and the dynamics of accumulation of carbon-containing polymer degradation products in the viscera were studied. The main targets for the particles are liver tissues, as well as renal and splenic tissues. The polymeric matrix of the microparticles is most actively destroyed in the spleen and liver. The presence of high-molecular- weight polymeric matrix in organs indicates the integrity of microparticles and the possibility of long-term (up to 12 weeks) functioning of polymeric particles in vivo.

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 dynamics of the amino acid composition of the medium was investigated during perfusion of the dog liver and kidney for 6 h with a mixture of autogenous plasma and medium No.199 in the ratio of 2:3. During culture of the kidney for 6 h the histidine concentration in the medium increased by 2.2 times compared with initially, the concentration of glutamic acid by 1.7 times, and of alanine and lysine by 1.6 times, whereas the concentrations of arginine, serine, and aspartic acid fell by 3.3 times and those of glutamine with threonine by 2.5 times. During perfusion of the liver the concentration of glutamic acid rose by 2.9 times, of alanine by 2.3 times, cystine by 2.0 times, and glycine by 1.5 times. The concentration of tyrosine fell by half, and that of phenylalanine and serine by 1.4 times. The arginine concentration fell so quickly during perfusion of the liver that by the second hour after the beginning of perfusion no arginine could be found in the medium. The method of amino acid analysis during organ culture as described can be used as a method of developing and correcting culture media.

Аннотация: The dynamics of the amino acid composition of the perfusion fluid was investigated during adequate perfusion of isolated dog organs (the thorax and a complex consisting of the thoracic organs, kidneys, and liver). The concentration of amino acids such as histidine, lysine, and alanine in the perfusion fluid 6 h after the beginning of perfusion of the organ complex was higher, whereas that of arginine, serine, aspartic acid, threonine with glutamine, isoleucine, proline, leucine, and valine was much lower than initially. In experiments on the isolated thorax the dynamics of the amino acid composition of the medium was studied during perfusion for 4 h. The concentration of alanine, lysine, and histidine in the medium increased, whereas those of serine, aspartic acid, isoleucine, tyrosine, and phenylalanine decreased.

Аннотация: Treatment of patients with mechanical jaundice (MJ) has been one of the topical problems of current medicine. The fraction of patients having MJ of oncologic character that can undergo radical surgery does not exceed 25-30%. A way out of such situation is to use minimally invasive endobiliary interventions, the main type of which is endoprosthesis replacement of bile duct lumens. The aim of the work was to study the biological properties of the experimental models of polymer stents made of PHA for endobiliary prosthetics and to investigate the biological properties of PHA suture material for forming of biliary-enteric anastomoses (cholecystoduodenostomy). Experiments were performed on 20 adult mongrel dogs, weighing 10-12 kg. The animals were divided to three groups: the negative control group (intact animals); the positive control group (the animals with implanted endobiliary silicon stents); and the experimental group (the animals with the PHA stents). The animals were monitored for 100 days. The clinical blood analysis was made before the operation, on day 7, 30, 60 and 100 days. During autopsy the presence of exudate, commissural process in the free abdominal cavity and subhepatic spatium, the appearance of choledoch where the prosthesis was located, as well as the appearance of cholecystoenterostomy, liver and duodenum. We did not found any signs of inflammation, cicatrical changes were estimated in the free abdominal cavity and subhepatic spatium. All implanted PHA stents were at their initial places of implantation. After the end of the experiment inflammatory reaction and anastomositis were absent. Macroscopic changes of liver and duodenum were also not detected. Liver function did not have any pathological deviations. These positive results give grounds to conclude that application of PHA as endobiliary stents in reconstructive surgery of bile passages and as suture material is a promising technology.

Аннотация: Hematological parameters and the state of liver cells of rats were examined in vivo after the animals received aflatoxin B(1) (AfB(1)) alone and together with modified nanodiamonds (MND) synthesized by detonation. The rats that had received the MND hydrosol had elevated leukocyte levels, mainly due to higher granulocyte counts and somewhat increased monocyte counts compared to control rats. Hematological parameters of the rats that had received AfB(1) alone differed from those of the control rats in another way: total white blood cell counts were significantly lower due to the decreased lymphocyte counts. In rats that had consumed AfB(1) with the MND hydrosol, changes in hematological parameters were less pronounced than in rats that had consumed either AfB(1) or MND. Electron microscopy showed that hepatocytes of the rats that had received the MND hydrosol or AfB(1) with the MND hydrosol contained elevated levels of lipid inclusions and lysosomes. Hyperplasia of the smooth endoplasmic reticulum (EPR) was revealed in liver specimens of the rats that had received AfB(1). Results of the study suggest the conclusion about mutual mitigation of the effects of nanoparticles and the mycotoxin on rats blood and liver cells after AfB(1) has adsorbed on MND.

Аннотация: The bioaccumulation of actinide Am-241 from food and water in bodies of freshwater fish (Carassius auratus gibelio, silver crucian carp) has been investigated in laboratory experiments. Homogenized biomass of submerged macrophytes labeled with Am-241 was injected into the fish gullet. Internal organs and tissues of crucian carp could be ranked according to activity concentration of dietary Am-241 after depuration of the digestive tract as follows: liver > gonads > bones > muscles. Accumulation of waterborne Am-241 in internal organs and tissues of crucian carp mainly occurred via the digestive tract. While the concentration of Am-241 in liver of crucian carps decreased during depuration time, its concentration in bones increased indicating slower transfer of Am-241 to skeleton compared to muscles and liver. The retention of dietary Am-241 in the bodies of crucian carp reached 35%-46% of ingested Am-241: 20%-31% was retained in liver, 0.6%-0.8% in skeleton, and 1.4%-2.0% in muscles. The concentration factor of Am-241 from water was 0.4 for the whole body, 0.3 for liver, 0.01 for muscles, and 0.01 for skeleton. Trace amounts of Am-241 were recorded in viscera and muscles of a wild population of silver crucian carp inhabiting a radioactively contaminated part of the Yenisei River.

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.
