    Opis:
    Ellagic acid (EA) is a natural antioxidant, belonging to the group of polyphenolic compounds. It displays a broad spectrum of pro-health effects, ranging from the prevention of cancer to antiviral properties. It is present in many fruit from the rose family (Rosaceae): strawberries, raspberries, blackberries and walnuts as well as cranberries and grapes. The available literature states that the fruit of roses, in addition to their aesthetic and functional applications, also show therapeutic properties, which, among other things, are associated with a high content of polyphenols, including ellagic acid derivatives. The aim of this research was to determine the differences in the content of free ellagic acid in the fruit of selected rose species. The test material consisted of freeze-dried sublimation and ground fruit from the following species of roses: R. canina, R. moyesii, R. pendulina. The fruit was separated into two fractions: flesh and seeds. Quantitative analysis of free ellagic acid was carried out by spectrofluorimetry. The free EA was present both in the flesh and in the seeds of the studied species of roses. Its content in the mentioned fractions varied depending on the species. The flesh of R. pendulina was characterised by the highest level of EA in free form (247.72 μg·g–1 of dry weight). The seeds of R. moyesii proved to be the most abundant in free EA (105.69 μg·g–1 of dry weight).

    Opis:
    Behaviour of macrophages in experimental mice trichinellosis, was investigated using the immunoenzymatic technique with monooclonal antibodies CD11b/CD18 within the framework of avidin-biotin-DAB. The maximum and earliest mobilization of macrophages 7 day post infection (dpi) was observed in the lamina propria of the intestinal mucosa. The highest level of macrophages in the muscles tissue was noted on day 21 of infection, however as early as in 28 dpi, their maximum level was observed inside the larval capsules. They line, especially between 35-42 dpi internal capsule surphace.

    Opis:
    In the course of trichinellosis in mice the numerous cells inside larval capsules were observed. Beginning on 14 day post infection (dpi) they were seen in about 7% of infected muscles fibers but at 21 dpi the percentage of capsules with the cells amounted to 77. In the next stage of infection the number of capsules containing cells continued to increase and reach almost 100% at 60 dpi. The identification of the cells was carried out by the indirect immunoenzymatic method using anti-CD4⁺, anti-CD8⁺ and anti-macrophage (Mac-1 antigen) monoclonal antibodies. In course of observation the level of CD4⁺ cells decreased from 11.3 to 0.7, of CD8⁺ from 17.7 to 3.0 and of macrophages from 71.0 to 23.1 %. The most numerous CD4⁺ cells were seen at 14 dpi while the CD8⁺ and macrophages at 21 dpi. Beginning on 28 dpi negatively reacting cells inside larval capsules were also observed. The number of these cells increased from 23.8 to 73.2% at 60 dpi and their identification requires further investigations. The role and the function of all these cells are discussed.

    Opis:
    The Stajnia Cave is one of the most important archaeological sites due to the finds of the first remains of Neanderthals in Poland, and several tens of thousands of flint artefacts from the Middle Palaeolithic. Based on geological, geochemical, palaeobotanical, palaeozoological, archaeological and isotope analyses, coupled with absolute age determinations (OSL, U-Th and C14), 15 lithostratigraphic layers were distinguished and palaeoenvironmental conditions during the sedimentation of these beds were determined. The cave loams accumulated through weathering, aeolian and fluvial processes. Their age may be correlated with an interval from the Early Glacial to the Late Pleniglacial of the Visulian (Weichselian) Glaciation. Archaeological relics related to the Neanderthals have been discovered in layer D with an absolute age of about 52,000–45,000 years BP and correlated with MIS 3 – the Middle Plenivistulian (Interplenivistulian). Climate oscillations in the Vistulian are reflected by the type of the sediments and their physical-chemical features, allowing determining warmer interstadial and colder stadial periods. Generally, the climate was cold, characteristic of tundra areas with a typical vegetation and fauna, and with the mean temperature of the warmest month not exceeding 12°C. Based on multi-proxy studies it can be concluded that from layer E1 upwards, the climate conditions became progressively drier. At that time, the climate was cold with continental features enhancing tundra domination. This conclusion is confirmed by palaeontological investigations and the record of stable oxygen isotopes in the teeth of reindeer. The studies have also indicated seasonal migration of reindeer on the tundra that surrounded the cave. Probably, short-term slight climate warmings occurred during the Middle Plenivistulian (Interplenivistulian).
