    Opis:
    The study analysed the relationship between the granulometric composition of grassland soils as determined by laser diffraction and their content of mineral forms of nitrogen and organic carbon. The content of mineral forms of nitrogen (NO3-N and NH4-N) in soil samples - after their extraction with 1% solution K2SO4 , was determined by flow colourimetry. Soil organic carbon content was determined using the Tyurin method. The study examined soil samples collected from 169 control and measurement sites located in different regions of Poland in terms of conditions for agricultural production. Statistical analyses of the research results showed that the grain size of grassland soils had a significant effect on their ammonium nitrogen content but not on their nitrate nitrogen and organic carbon content. In this respect, it was found that there was a positive correlation between the share of the sand fraction and the content of ammonium nitrogen in soils and an opposite relation between the share of coarse silt, fine silt and clay and the content of the aforementioned component. Results of the analyses differ considerably from the results of studies by other authors on the influence of soil grain size distribution on the content of mineral nitrogen and organic carbon in soils based on classical methods of measurements of soil particle size distribution. There is a need to develop solutions to convert and compare results obtained by laser diffraction and standard methods.

    Opis:
    The aim of the study was to assess the P-PO4 and N-NH4 pollution of water in grasslands located on peat soils and to identify the impact of groundwater level on this pollution formation. The research was conducted in 2000-2010 on grounds of ITP-PIB in Biebrza village (Poland). Within lowland fen a total of 18 monitoring points of groundwater and watercourses were established in 6 separate test stands. The subject of the research was water collected from drainage ditches/channels and groundwater, which was taken from wells installed in organic-soil layer and wells whose bottom was 15-20 cm below this layer. Water samples were collected several times a year, and in the case of groundwater, its level was also measured. It was found that: 1) due to concentration level of P-PO4 and N-NH4, about 46 and 39% of water samples from organic-soil layer and more than 40 and 37% of water samples from mineral-organic-soil layer respectively, were characterized by poor chemical status; 2) due to the exceeding of the limit values of P-PO4 and N-NH4 concentration, water samples from watercourses in over 30 and 27% respectively were not within 1st and 2nd class of surface water quality; 3) P-PO4 and N-NH4 concentrations in each water type were statistically significant and positively correlated with each other; 4) in organic-soil layer the groundwater level changing every 10 cm was a statistically significant factor differentiating the average P-PO4 concentration in roundwater associated with mineral-organic layer of peat soil and average N-NH4 concentration in each type of water.

    Opis:
    Background: Diverticulosis is the most common finding in the GI tract. Nearly half of the people with diverticula experience symptomatic uncomplicated diverticular disease (SUDD). Aims: The primary endpoints of our study were to assess the effectiveness of combined therapy with rifaximin-α and arabinogalactan-lactoferrin in symptom reduction and normalization of bowel movements. The secondary endpoints were an assessment of efficacy in SUDD recurrence prevention and patients’ compliance to the combined therapy. Material and methods: A retrospective observational survey study was performed in 2019 among physicians experienced in diverticular disease (DD) treatment in Poland. Patients with previous episodes of recurrences treated with combined therapy (cyclic rifaximin-α at least 400 mg b.i.d/7 days/every month and continuous arabinogalactan-lactoferrin supplementation 1 sachet daily) were assessed after 3 and 6 months regarding symptoms’ resolution in the three-point scale. The patients’ SUDD history, diagnostic methods, treatment, and results, as well as patients’ compliance were evaluated. Results: 281 patients met inclusion criteria, and were further evaluated (67.6% women, median age 65 years). After 6 months of combined treatment, there was statistically significant reduction in the total severity score (sum from 8.5 [max 15 points] to 1.28; p < 0.0001); and improvement in each symptom score (median from 1.7 [max 3 points] to 0.26; p < 0,001). Stool frequency statistically normalized in every group. As many as 31.7% had complete symptom resolution. Patients’ compliance with the therapy was very good and good in 92.9% of cases. Conclusions and discussion: Combined therapy with cyclic rifaximin-α and continuous arabinogalactan combination with lactoferrin is effective in SUDD treatment in terms of symptom resolution, bowel movement normalization, prevention of recurrences with very good patient’s compliance.

    Opis:
    Dust mite allergens are common factors causing bronchial hypersensitivity in children with diagnosed bronchial asthma. As one of the main type of allergens in the domestic environment, they take a signifi cant part in this process. The authors studied the severity of bronchial asthma (according to GINA 2006) of 16 children and teenagers with confi rmed allergy to mites, who lived in the city situated in Upper Silesia, in correlation to acarofauna of their dwellings. Mite species, their number in 1 g of dust and guanine concentration in 1 g of dust (Acarex test) were examined in 57 house samples from 16 houses or fl ats. The dominant species were Dermatophagoides farinae and D. pteronyssinus; other species of mites, such as: Euroglyphus mayenei, Gymnoglyphus longior, Acarus siro, Tyrophagus putrescentiae, Lepidoglyphus destructor, Lepidoglyphus fustifer occurred only sporadically. There was no correlation found between the severity of bronchial asthma and the level of exposure to mite allergens from household environments in the studied group of mite-sensitive children and teenagers.
    U dzieci z astmą oskrzelową alergeny roztoczy kurzu domowego są często czynnikami powodującymi nadreaktywność oskrzeli. Jako jedne z głównych alergenów w środowisku domowym mają w tym względzie duże znaczenie. Autorzy poddali analizie stopień ciężkości astmy oskrzelowej (wg GINA 2006) u 16 osób w wieku rozwojowym mieszkających w mieście na Górnym Śląsku), wykazujących alergię na roztocze, w odniesieniu do akarofauny kurzu z ich mieszkań. Pod uwagę wzięto gatunki roztoczy, ich liczbę w 1 g kurzu oraz stężenie guaniny w 1 g kurzu (Acarex test). Dominującymi gatunkami były D. farinae i D. pteronyssinus, a inne gatunki roztoczy (Euroglyphus mayenei, Gymnoglyphus longior, Acarus siro, Tyrophagus putrescentiae, Lepidoglyphus destructor, Lepidoglyphus fustifer) występowały sporadycznie. Nie stwierdzono zależności stopnia ciężkości astmy oskrzelowej od stopnia narażenia na alergeny roztoczy w środowisku domowym osób objętych badaniem.

    Opis:
    Introduction. Breast cancer (BC) makes up nearly 26% of malignant tumours worldwide and is the leading cause of cancerrelated deaths in European women. With approximately 18,000 new cases of BC diagnosed in Polish women annually, breast cancer liver metastasis (BCLM) is respectively an increasing issue. Recent data found in literature indicates improved survival following liver resection with systemic therapy. Objective. The aim of study was to evaluate surgical treatment in patients with isolated BCLM. Materials and method. During 2009–2013, a retrospective study was undertaken and 30 cases analysed. From nearly 2,000 liver resections performed, 11 female patients at the mean age of 59.18 years with BCLM were qualified for surgery. Results. The median time between primary and secondary treatment was 3.5 years (1–7). One patient (9.1%) presented an extrahepatic lesion – bone metastasis. The left lobe, right lobe and both lobes of the liver were affected, respectively, in 3 (27.3%), 4 (36.4%) and 4 (36.4%) patients. 5 patients (45.5%) presented single hepatic lesion, in contrast to the maximum number of lesions which equalled 6 in the right lobe. Average hospitalisation period was 13.27 days and discharge on the 11.3 postoperative day. One-year survival was 72.7% (8 patients); therefore, three-year survival was 36.4% (4 patients). Conclusions. Oncological centres should assess BCLM patients more openly and qualify them for hepatic resection along with adjuvant systemic treatment in order to improve overall survival. This, however, needs to be studied in a multicentre randomized trial.
