Opis:
The Migration Period on the present Polish territories is considered as a time of depopulation of Oder, Warta, and Vistula basins. The prerequisite for such assumption is lack of the archaeological finds in these regions. In contrast, on the Mrągowo Lake District and in the Lyna basin, one can find wealth of burial crematory equipped with items from the Roman period and made in the Germanic style. The analyses using the physics techniques gives an opportunity to the meeting of history with the contemporary times and the lost things may see the light of present day. The discovered artefacts may constitute a source of knowledge, which, after analysis, will be able to fill the gaps on the map of settlements in the Polish territories. The energy-dispersive X-ray fluorescence system was used to analyze the set of Polish archaeological artefacts found in an excavation in Masurian Lakes District. The compact X-ray tube developed in the National Centre for Nuclear Research (NCBJ) was used as an X-ray source in the system designed for the energy-dispersive X-ray fluorescence studies. The X-ray fluorescence spectra of the artefacts were registered with the Amptek SDD spectrometer and the concentrations of elements were determined. The measurements show that the X-ray system developed in NCBJ with transmission type X-ray tube and the Amptek SDD spectrometer is an effective tool for chemical composition analyses of archaeological objects and can be successfully applied in archaeometry.

Opis:
An interdisciplinary study of metallic objects from selected archaeological sites in Poland was performed. The aim of the project was to obtain information about the chemical composition and structural changes of the objects. Furthermore, the research results provided information about the technological process which was used to manufacture the artifacts. The materials research had a non- and micro-invasive character which is very important in this type of investigation. The main experimental tools were particle-induced X-ray emission supplemented with nuclear reaction thermal neutron (white beam) radiography, scanning electron microscopy with X-ray energy dispersive analysis, and laser ablation inductively coupled plasma mass spectrometry techniques. The results show that the artifacts were made by a secondary smelting process used in local metallurgy manufactures.

Opis:
In this study, we assessed the effect of a humic-fatty acid preparation (HFA) used in rabbit feed on certain haematological and biochemical serum parameters (the lipid profile and the Ca, P and Fe contents). A higher RBC, HGB and HCT values were observed in the groups that were given HFA. An increase in Fe concentrations were also noted. The total and LDL cholesterol were lower in the groups which received HFA than in the control group.

Opis:
The aim of the in vitro study was to determine the effect of corn dried distillers grains with solubles (corn DDGS), used as a replacement for the concentrate ingredients of sheep diet, on rumen fermentation. The material for the study was the ruminal fluid of Polish Merino sheep which was incubated during 4-, 8- or 24-hour periods. Five groups of samples were prepared for in vitro fermentation: C – control, incubated with the substrate consisting of the concentrate ingredients; D1, D2 and D3, where DDGS was used as a substrate added in proportions of 10, 20 and 30% of dry matter of the concentrate; and D4, where 100% DDGS was used as a substrate. After fermentation, the gas and short chain fatty acids (SCFAs) analyses were performed using gas chromatography. The ammonia concentration and pH were also determined, and the SCFA utilization index (NGR), the fermentation efficiency (FE) and the index of cell yield of ruminal microorganisms (CY) were calculated. This research showed no effect of DDGS on the methane emission. The positive correlations between the amount of methane and ammonia concentrations in the 8- and 24-hour fermentation periods were found. DDGS addition increased propionate proportion, but decreased production of acetate (p<0.01). Additionally, D1, D2, D3 and D4 substrates lowered isobutyrate (p<0.05) and isovalerate (p<0.01) production. Based on the results obtained, it can be stated that partial substitution of the concentrate ingredients with DDGS did not have deleterious effect on sheep rumen fermentation processes.

Opis:
The effect of W92/72 transgenic flax seeds taken from a variety of Linola on the production of SCFA, ammonia and methane by bacteria inhabiting rabbit caecum was studied. The in vitro method was used where caecal contents from rabbits was incubated with W92/72 transgenic or Linola flax seeds, or without any additives (control samples).The total concentration of SCFA was higher in samples with the addition of flax seeds than in the control samples. The increase in concentrations of acetic, propionic and butyric acids was the highest in samples with Linola seeds added. A higher percentage of propionic and butyric acids was observed in the contents incubated with addition of flax seeds as compared to the control samples. This increase was the result of a percentage decrease in acetic acid. No differences were observed in the concentration of ammonia between fermented samples. Moreover, the addition of flax seeds resulted in slight decrease of pH in incubated samples. In gas samples, the methane level was higher in samples with flax seeds added, although the highest level was found in samples with transgenic seeds.In addition, gas pressure was significantly higher in samples with flax seeds added as compared to control samples, and this may indicate a higher intensity of microbiological fermentation processes. These studies suggest that neither Linola nor W92/72 flax seeds have any unfavorable effect on the caecal microflora activity of rabbits. A beneficial influence of flax seeds on the microbiological fermentation process in rabbit caecum was observed, based on an increase in percentage ratio of propionic acid in samples with flax seeds added.

Opis:
The effect of adriamycin on the behaviour of CD4⁺ and CD8⁺ cells in the course of trichinellosis in mice has been studied. The animals infected with 200 larvae per mouse were administered intraperitoneally adriamycin (Adriblastin from Farmitalia) at 1st and 28th day post infection (dpi), in a dosis of 0.2 mg. The mice were killed weakly for 6 weeks and then at the 60th dpi. The examinations were made on histologic sections from the spleen, mesenteric lymph node, jejunum and masseter muscle using immunofluorescent and immunoenzymatic methods with monoclonal antibody. The mice receiving adriamycin exhibited more CD8⁺ cells in the intestinal mucosa and by the end of the experiment also in the muscles in comparison with the control animals, which, however, did not affect the course of the infection.

Opis:
Studies were undertaken to evaluate by parasitological techniques the course of intestinal and muscular invasions in mice infected with Trichinella spiralis and treated with TFX-Thymomodulin (TFX-Th). Studies were conducted on 120 mice of BALB/c and SWISS strains, infected each with a mean invasive dose of 300 T. spiralis larvae. TFX-Th (Thymoorgan GmbH Pharmazie Co. KG, Vienenburg, Germany) was administered subcutaneously at 30 mg/kg body weight. Depending upon duration of TFX-Th administration and stages of intestinal and muscular invasions, three experiments were distinguished in the study. The results indicated that TFX-Th promoted eradication of larvae from muscles, whether administered at the early of the late stage of T. spiralis invasion.
