    Opis:
    The aim of the study was to determine the activity of dehydrogenases and urease in forest peat soils of different fertility. There were selected 23 experimental plots localised in central and northern Poland. The research was conducted on forest fens, transition bogs and raised bogs. The biggest differences in soil physical and chemical properties were detected between fen and raised bog soils while raised bog soils and transition bog soils differed the least. Statistically significant differences between particular subtypes of peat soils were observed for soil pH-H2O, pH-KCl, C/N ratio as well as the content of organic carbon, nitrogen, calcium and potassium. The highest average dehydrogenase activity in the soil surface level was observed in fen soils, and the lowest – in raised bogs soils. The results obtained on urease activity were similar. Differences in urease activity in the studied soil types were shown. Dehydrogenase activity did not reveal statistically significant diversity. The activity of urease was negatively correlated with the content of carbon, C/N ratio, hydrolytic acidity and moisture. Also the increase in enzymatic activity accompanied by the increase in pH has been observed.

    Opis:
    Taking into account the progressive degradation of soils it is important to assess their quality. Soil quality depends on a large number of physical, chemical, biological and biochemical properties. In the publications available, there are presented three approaches regarding the use of soil properties to estimate soil quality: (1) the use of individual properties, (2) the use of simple indexes and (3) the use of complex indexes derived from combinations of different properties. The purpose of this study was to investigate the possibility to use enzymes as indicators of forest soil quality. Experimental plots (43) were located in central Poland. The study was carried out in a number of diverse fresh forest sites. To assess the quality of forest soils dehydrogenase and urease activity and the degree of base saturation were used. One of the final conclusions point out that enzymatic activity indicates current site condition as well as the changes that occur in soil better than soil physical and chemical properties. In other words, in comparison to soil enzymatic activity, soil physico-chemical properties constitute a less sensitive indicator of soil changes.

    Opis:
    The aim of this study was to assess the possibility of using biological and biochemical parameters in the evaluation of forest soil quality and changes caused by land use. The study attempted to determine a relationship between the enzymatic activity of soil, the number of earthworms and soil physico-chemical properties. The study was carried out in central Poland in adjoining Forest Districts (Przedbórz and Smardzewice). In soil samples taken from 12 research plots, basic physico-chemical properties, enzyme activity (dehydrogenase, urease) and density and biomass of earthworms were examined. Enzyme activity showed a large diversity within the forest site types studied. The correlations between the activity of the enzymes studied and C/N ratio indicated considerable importance of these enzymes in metabolism of essential elements of organic matter of forest soils. Urease and dehydrogenase activity and earthworm number showed susceptibility to soil pH, which confirmed relationships between enzyme activity and abundance of earthworms and soil pH in H2O and KCl.

    Opis:
    The objective of the paper was to estimate i) the carbon accumulation in soils of different forest site types as well as ii) its changes with regard to the depth of the soil profile. The investigation was carried out in the Przedbórz Forest District (central Poland) on 43 study plots, including different forest sites – fresh coniferous forest (Bśw), fresh mixed coniferous forest (BMśw), fresh mixed broadleaved forest (LMśw) and fresh broadleaved forest (Lśw). On each plot soil pits were dug and samples for laboratory analysis were collected. The following characteristics were determined in the soil samples: pH, the content of organic C and total N, particle−size distribution, the content of exchangeable Ca, Mg, Na and K, and hydrolityc acidity. The obtained results demonstrated that soils of Bśw, BMśw and LMśw sites characterized by higher carbon accumulation in surface horizon to 50 cm depth compared to the most eutrophic sites (Lśw). The rate of carbon accumu− lation in forest soils depend on the humus type which is connected with species composition of stands. Domination of Scots pine in stand affects the formation of ectohumus and leads to higher C accumulation in surface horizons on Bśw, BMśw and LMśw sites. In soils of Bśw, BMśw and LMśw sites carbon stored in the horizons to 50 cm constitutes 64−94% of the total carbon accu− mulated, while on the eutrophic sites (Lśw) this share amounts to 39−72%. The value of the total carbon stock in soils of fresh forest sites can be estimated on the basis of carbon stock in horizons to 50 cm depth.

    Opis:
    The aim of this paper is to present the properties of soils and topography conditions of Norway spruce forests growing on the limestone (Polysticho−Piceetum) in the upper part of the lower montane zone. The study was conducted in the Tatra Mts. (southern Poland) on six study plots reflecting the living conditions of spruce forest on limestone. On each plot the topography conditions were described, soil pits were dug and samples for laboratory analysis were collected. The following characteristics were determined in the soil samples: pH, the content of C and N, particle size, the content of Ca, Mg, Na and K, exchangeable acidity, aluminum content and hydrolityc acidity. For each study plot the stand characteristics were measured (diameter at breast height and height). The Soil Trophic Index for mountain areas (SIGg) was calculated on the basis of <0.02 mm fraction content, the sum of exchangeable base cations, soil acidity and the total content of N and C organic in the humus−mineral horizon. Polysticho−Piceetum stands in the upper part of the lower zone between 1000 and 1200 m above sea level developed in the unique geomorphological and geological conditions. They covered very shallow weathered fragments of limestone or steep slopes with fine−grained scree of carbonate rocks. Rendzic Hyperskeletic Leptosols (Humic) and Calcaric Lithic Leptosol are soils typical for analysed spruce stands. Character of site was reflected in the SIGg values that ranged between 15 and 20. The moder−mull and tangel−mor humus type was found on the majority of the investigated plots. Low fertility of soil was confirmed by the site index of analysed stands (IVth and Vth class).

    Opis:
    The main aim of study was to present the stock and structure of deadwood in different site conditions. In total. sixteen study plots were established on wet broadleaved forest (Lw) and riparianalder forest (OlJ) sites. The objective was to determine the carbon accumulation in lying dead trees. The investigation was performed in the Czarna Rózga reserve in Central Poland (50°5937N; 20°015E). All live and dead trees were measured on each plot. The species of both live and dead trees were identified as well, and the decay class of the dead trees was assessed. Additionally, samples of different species wood from lying logs in five decay classes were taken for carbon content determination. The study was carried out in the spring of 2017. The average stock of deadwood in the Czarna Rózga reserve on the wet broadleaved forest site amounted to 47 m3/ha, while on the riparian alder forest site it equaled 52 m3/ha. The high stock of deadwood can be explained by the slowdown of decay processes by humidity and anaerobic conditions. Ash was the dominant species in the deadwood pool. Regardless of the site conditions (Lw or OlJ), the stock of ash deadwood was several times higher than the stock of live trees this species. The greater carbon stock in lying dead trees was recorded in riparian alder forest.

    Opis:
    The aim of this study was to assess the effects of different types of land use (forest, tillage and pasture) on soil properties, especially enzymes activity. Our investigation was carried out on 53 research plots with 11 plots in broadleaved forest stands, 12 plots in mixed broadleaved stands, 10 plots in mixed coniferous stands, 9 plots on tillage and 11 plots on pasture. The soil samples were collected from a depth of 0–15 cm after removing the organic horizon. Contents of organic carbon and nitrogen, pH and soil texture were investigated. Furthermore, dehydrogenase and urease activity were determined. Significant differences in the enzyme activity between forest and agricultural soils were observed, thus demonstrating that enzyme activity is influenced by the organic matter content of the soil. The highest enzyme activity was recorded in the forest soil within broadleaved stands, whilst the lowest activity was found in tillage soil, because tillage soil contained significantly less organic matter. High enzymatic activity of pasture soils is the combined result of vegetation type and the lack of plowing.

    Opis:
    The paper presents the properties of soils of eutrophic fir forest stands in lower montane zone in Beskid Niski and Beskid Sądecki Mts. (southern Poland). Efforts were made to put some order in the issues related to the site system, in which the fir plays a dominant role. The study was conducted in 10 study sites reflecting the living conditions of eutrophic silver fir forest. On each plot the topography conditions were described, soil pit was done and samples for laboratory analysis were taken. We determined the following soil characteristics: pH, the content of C and N, particle size, the contents of Ca, Mg, Na and K, exchangeable acidity, aluminum content and hydrolityc acidity. Additionally, diameter at the breast height and height of firs were measured. Cambisols (Epidystric, Hyperdistric and Eutric) are soils typical for eutrophic fir forest stands. The study confirmed that the eutrophic fir forests occupy mainly moderately cool slopes: north, east and north−east. The eutrophic fir forests prefer the lower parts of the slopes or low hills. Eutrophic nature of the soil occupied by the fir forests confirms the quality of accumulated humus. The mull humus type was found the most frequently. Only in two cases moder humus type was noted. The advantageous properties of humus−mineral horizon reflects decomposition level of organic matter expressed as the proportion C/N (range from 11.2 to 19.1). Particle size of Cambisols of eutrophic fir forest stand was very diverse and was associated with the nature of the parent material. Fertility of the soils was reflected in the trophic soil index for mountain area (SIGg=30−37), which was confirmed by the high site index of these stands.

    Opis:
    The experimental plots used in the study were located in the middle forest zone (elevation: 900-950 m a.s.l.) on two nappes of the flysch Carpathians in southern Poland. The aim of this study was to assess the effects of serpentinite in combination with nitrogen, phosphorus, and potassium fertilizers on selected chemical properties of the soil and activity of dehydrogenase and urease in the studied soils. All fertilizer treatments significantly enriched the tested soils in magnesium. The use of serpentinite as a fertilizer reduced the molar ratio of exchangeable calcium to magnesium, which facilitated the uptake of magnesium by tree roots due to competition between calcium and magnesium. After one year of fertilization on the Wisła experimental plot, the pH of the Ofh horizon increased, while the pH of the mineral horizons significantly decreased. Enrichment of serpentinite with nitrogen, phosphorus, and potassium fertilizers stimulated the dehydrogenase activity in the studied organic horizon. The lack of a negative effect of the serpentinite fertilizer on enzyme activity in the spruce stand soil showed that the concentrations of the heavy metals added to the soil were not high enough to be toxic and indicated the feasibility of using this fertilizer in forestry.

    The subject of this study were soil requirements of common woody shrubs, which may be part of the forest understory (Sorbus aucuparia L., Frangula alnus Mill., Corylus avellana L., Juniperus communis L., Padus avium Mill., Euonymus europaea L., Sambucus nigra L.). We focused on phytocenoses in the vicinity of natural forests in reserves and national parks of Polish lowlands and defined optimal types and subtypes of soil with trophic variations for each underwood species. The range of trophism for each species of shrub was determined using specific physicochemical properties of the soils, while soil quality was assessed using the Soil Site Index (SIG) (Bro¿ek et al. 2011). The ecological requirements of the before-mentioned underwood species were linked with forest typology as well as natural vegetation and they showed different soil requirements. Here we report significant differences in particle size and dynamics of organic matter decomposition in soils associated with these underwood species.

    Opis:
    Dehydrogenases are exclusively intracellular enzymes, which play an important role in the initial stages of oxidation of soil organic matter. One of the most frequently used methods to estimate dehydrogenase activity in soil is based on the use of triphenyltetrazolium chloride as an artificial electron acceptor. The purpose of this study was to compare the activity of dehydrogenases of forest soils with varied physicochemical properties using different triphenyltetrazolium chloride assays. The determination was carried out using the original procedure by Casida et al., a modification of the procedure which involves the use of Ca(OH)2 instead of CaCO3, the Thalmann method, and the assay by Casida et al. without addition of buffer or any salt. Soil dehydrogenase activity depended on the assay used. Dehydrogenase determined by the Casida et al. method without addition of buffer or any salt correlated with the pH values of soils. The autoclaved strongly acidic samples of control soils showed high concentrations of triphenylformazan, probably due to chemical reduction of triphenyltetrazolium chloride. There is, therefore, a need for a sterilization method other than autoclaving, ie a process that results in significant changes in soil properties, thus helping to increase the chemical reduction of triphenyltetrazolium chloride.

    Opis:
    The physical and chemical properties of soil are the basic features that are used in the assessment of mountain sites. The aim of this study was to produce a simple key for classifying forest sites in mountain areas using soil particle size distribution. 200 plots (standard typological space) were selected for examination, most of which are typical of the Carpathians – being dominated by flysch rock. A few plots were located in the Sudety and Tatra Mountains, which have a different surface geology, mostly metamorphic rock and granite. The study proved that soil properties (reaction, base saturation, content of base cations, organic carbon and nitrogen) are helpful in distinguishing and assigning soils to particular site types. The particle size distribution of forest mountain sites separated into different categories in terms of productivity. These results can be used to improve the classification of forest mountain sites.

    Opis:
    The aim of the study was to determine the effect of different management treatments of Norway spruce post−harvest logging residues on soil properties. The study compared the impact of residues chipping and arrangement into the stacks. The investigation was carried out in the Nowy Targ Forest District (southern Poland). 15 research plots were selected for the analysis (5 plots with wood chips, 5 with stacks and 5 control ones). In May 2018, on each research plot soil samples for laboratory analysis were collected from the surface horizon (0−10 cm depth). Basic properties (pH, carbon and nitrogen content, base cations content) and enzyme activity (dehydrogenase, urease and−glucosidase) were determined. The obtained results confirm the influence of post−harvest logging residues management on soil properties. The significant differences in soil carbon content between soils of different plots variants were noted. Soils of research plots with wood chips and stacks were characterized by higher content of carbon compared to the control research plots. At the same time soils with post−harvest logging residues had a higher biochemical activity expressed by enzymatic activity. The nutrients released from decaying post−harvest logging residues stimulated the microbiological activity of the soils.

    Opis:
    The aim of this study was to present the relationship between soil properties and biodiversity indexes in upland fir (Abies alba) forest associations (Abietetum albae). Our study was conducted in six areas representing the growth conditions of upland fir forests and the research plots were located in the Roztoczański and Świętokrzyski National Parks as well as Przedbórz, Radomsko, Piotrków and Janów Lubelski Forest District. On every plot, the topography was described, soil cores were examined and samples for laboratory analysis were taken. The following characteristics were determined for the soil samples: pH, C, N, Ca, Mg, Na and K content, particle size, exchangeable acidity, aluminum content and hydrolytic acidity. Additionally, enzyme activity in the soil samples (urease and dehydrogenase) was measured. In each test area, the stand characteristics were measured (diameter at breast height and height) floristic characteristics were described and the biodiversity indexes (Shannon, Simpson and Margalef indexes) were calculated. Different soil types (Gleysols, Brunic Arenosols, Gleyic Podzols and Hyperdistric Cambisols) were recorded for the investigated forest stands and the soils were categorized according to soil texture, C content, enzyme activity and different humus types (moder-mor, moder, moder-mull). The upland mixed coniferous forest sites were characterized by lower biodiversity indexes (2,6 Shannon index; 0,72 Simpson index; 4,9 Margalef index) while the upland mixed broadleaf forest sites showed higher indexes (3,3 Shannon index; 0,87 Simpson index; 9,4 Margalef index). The site index obtained for the fir stands confirmed these results.

    Opis:
    In recent years, we face a massive dieback of Norway spruce stands in Poland. The cause of this process may lay in the way of their monocultural silviculture. The correct assessment of the habitat conditions and soil properties in particular is the basis of the proper management of these forest areas. The aim of this study was to verify application of the trophic soil index for mountain areas (SIGg) in the assessment of site conditions for spruce stands with different health condition. Three types of spruce stands were distinguished: degenerated, weakened and stable. In total, 32 study plots were established in following forest districts in southern Poland: Ustroń, Wisła, Bielsko, Węgierska Górka, Jeleśnia, Ujsoły and Lądek Zdrój. The SIGg was calculated on the basis of <0.02 mm fraction content, the sum of exchangeable base cations, soil acidity and the total content of N and organic C in the humus−mineral horizon. These attributes are useful to determine the potential productivity of the soils did not differentiate visibly the analyzed stand variants. The soil in degenerated and weakened spruce stands showed higher degree of acidity and less the content of base cations compared to soils of stable spruce stands. Mountain trophic soil index can be applied in the assessment of the forest sites potential. Although it does not enable to monitor the disturbances in the nutrients circulation, the detailed analysis of its components allows for precise assessment of the forest sites status.

    Opis:
    The correct assessment of the site conditions is the basis of the good management of forest areas. The aim of this study was to find a set of soil properties, which allow separating the diverse sites in terms of the soil productivity. We used 180 locations in the Carpathians and the Sudety Mountains for testing. The study plots were located in transects from the foothills to the top along the slopes, taking into account the variability of site conditions, geological substrate and exposition. The index was calculated on the basis of the content of <0.02 mm particles, the sum of exchangeable base cations, soil acidity and the ratio between total N content and organic C in the humus−mineral horizon. The soil trophic index for mountain areas (SIGg) that include the climatic factor was introduced. The factor is defined as the 650/altitude ratio for a given point above sea level. In the mountains, the content of <0.02 mm fraction, the sum of exchangeable base cations and soil acidity were determined in the column of 1 m² of the soil cross section and depth of 1 m (1 m³ of volume) due to the lower depth of the soil profile. The SIGg correctly separates soil of different productivity as the properties closely associated with the stable elements of the soil, expressing its production and properties, which reflect the current state of the soil environment, were used in the construction SIGg.

    Opis:
    The aim of the study was to apply the forest soil trophic index (ITGL) in the assessment of post−agricultural soil under naturally regenerated silver birch (Betula pendula Roth.) stands. The study was conducted in Mazowieckie region (central Poland) in 10 locations (tab. 1). In each location we established 4 study plots with naturally regenerated silver birch of different age. The age of the investigated stands ranged from 2 to 17 years. On each study plot samples from three upper soil horizons (0−5 cm, 5−15 cm and 15−50 cm) were collected for laboratory analysis. The following characteristics were determined in the soil samples: pH, organic carbon (C) and total nitrogen (N) content, particle size and the content of exchangeable base cations (Ca, Mg, Na and K). These soil characteristics were on used for ITGL calculation. Chemical properties of soils under silver birch regeneration varied with regard to trees age, whereas physical attributes turned to be rather stabile over the time (tab. 2). According to ITGL value investigated soils were classified as eutrophic. It is probably the effect of high base cations content, which is a result of systematic fertilization during the long term agricultural use. The insignificantly different ITGL values for the studied soils (tab. 3) indicated their similarity in terms of site productivity potential and soil−geological characteristics. The soil properties, especially the quality of soil organic matter described with C/N ratio, improved several years after the cessation of agricultural activity and spontaneous afforestation. The obtained results indicate that silver birch can be used in the stand composition on post−agricultural areas.

    Opis:
    The study focused on the influence of several soil properties and forest species composition on spatial distribution of organic carbon stock in soils developed from the contrasted parent materials: Tertiary claystones and sandstones, and Qurternary sands of different origins. Soil sampling was performed on 110 plots, while forest mensuration was conducted on 82 ones. The content of <0.05 mm fraction determined by the type of parent material played a key role in the distribution of carbon stock in soils. Higher content of fine fraction favoured the accumulation in mineral part of soil, while higher sand content had an indirect influence on accumulation of carbon in the organic horizon. Forest species composition and biomass volume are more important for C accumulation in the O horizons. Taking into account the geological heterogeneity, the size of investigation area played a prominent role for the statistical significance of the observed correlations between carbon stocks and the other soil properties.

    Opis:
    The alkalization of soil is a common phenomenon in forest ground nurseries. Liming, inadequate fertilization and the use of hard water for irrigation are the main reasons for this alkalization. The aim of this study was to investigate the effect of fertilization with aluminium sulphate on soil pH, the activity of selected soil enzymes, efficiency as well as the growth parameters of pine seedlings. The study was conducted in a forest nursery, on a plot with soil pH 6.4 in water and 5.9 in 1MKCl. Such a pH is not conducive to the production of conifer seedlings, particularly pines. Two different doses of aluminium sulphate fertilizer were applied: 740 kg ha-1 and 1110 kg ha-1. Both doses significantly reduced the soil pH, whereas soil enzyme activity did not change. The lower dose had a positive impact on the growth parameters of pine seedlings, while the higher dose led to their deterioration. We observed statistically significant differences in average primary and lateral root lengths, number of short roots, and thickness of the neck root of seedlings. One- and 2-year-old seedlings did not show symptoms of nutrient deficiency and neither did concentrations of the investigated macronutrients and selected micronutrients in needles indicate such. After applying the higher fertilizer dose, we observed a favourable change in the composition of mycorrhizae. Out of the potential seedling pathogens we found Cylindrocarpon spp., Fusarium spp., Phytophthora spp., Pythium spp. and Rhizoctonia solani of which the most frequent were Fusarium oxysporum, Pythium spp. and R. solani. Their occurrence frequency differed between the treatments used in this experiment. This study confirms the positive effects of a low aluminium dose on the performance and growth parameters of pine seedlings. However, on the basis of the conducted experiments, it is difficult to say, whether this positive effect is due to a direct action of aluminium on the seedlings or rather an indirect effect caused by lowering the soil pH, which in turn impacts on mycorrhizae composition and hence pathogen development.

    Opis:
    The experimental plots were located in the middle forest zone (900– 950 m) on two nappes of the flysch Carpathians: Magura (the Ujsoły Forest District) and Silesian (the Wisła Forest District) in the spruce stands of age class 21– 40 years. Serpentinite was introduced in the autumn of 2008 on all plots while other fertilizers (N, P, NP and NPK) in the spring of 2009. Based on the chemical composition of soil solutions collected in lysimeters placed at the depth of 20 cm in the autumn 2008 and the spring and autumn 2009, ecochemical parameters were calculated: acid neutralization capacity (ANCaq), alkalinity (ALK), the degree of soil acidity (Ma%), acidic cations (Ma), saturation of the exchangeable complex of the soil solid phase (Mb) with alkalis, saturation with alkalis (BS), molar relations Ca/Al, Mb/Al, BC/Al. After the winter, soil solutions became acidic, especially in the Wisła Forest District. The saturation of the studied soils demonstrates moderate flexibility of soils in the Wisła Forest District in relation to acid load, and high flexibility of the Ujsoły soils. The opposite trend was observed for the degree of acidity of soils. Acid neutralization capacity and alkalinity of the waters showed significant variations in soil pH even in the case of small variations in the composition of the solution, if they were caused by the inflow of the anions of NO3 - and SO4 2-. After application of the fertilizers, an increase of Mg, Ca and Mb was noted in the soil solution, determined in the overlaying highly acidic organic horizons trough the ion-exchange buffering mechanism of highly protonated functional groups with high buffering capacity. Highly improved content of Mg in a soil, and in some cases – also the content of N, P and K, present potential improvement of forest growth capacity without the hazard of adverse side-effects of liming. Aluminum stress in the spruce is unlikely, while trees in the control plots in the Wisła Forest District may already be sensitive.

    Opis:
    Zredukowana forma glutationu jest jednym z najważniejszych przeciwutleniaczy występujących w organizmie człowieka, a niedobór tego związku prowadzi często do poważnych zaburzeń. Glutation bierze również udział w modulowaniu odporności, procesach detoksykacji, a także reguluje aktywność innych białek i enzymów. Jest on czułym wskaźnikiem wrażliwości organizmu na stres oksydacyjny a jego stężenie w poszczególnych narządach i komórkach może wskazywać na stopień ich uszkodzenia. Oznaczanie stężenia glutationu z wykorzystaniem technik chromatograficznych stanowi uzupełnienie a niejednokrotnie alternatywę w stosunku do innych metod analitycznych: enzymatycznych, spektrofotometrycznych, spektrofluorymetrycznych, elektromigracyjnych, chemiluminescencyjnych, czy magnetycznego rezonansu jądrowego. Do najważniejszych etapów przygotowania próbki należą: zabezpieczenie aminotioli przed wysoką temperaturą i działaniem substancji utleniających pochodzących z matrycy, odbiałczanie, redukcja disulfidów, a także derywatyzacja (z wyjątkiem technik elektromigracyjnych i tandemowej spektrometrii mas).
    Reduced form of glutathione is one of the most important antioxidants, which is found in human body. Deficiency of this compound can often lead to serious disorders. It plays a central role in immunity modulation, detoxification capacities and regulation of activity of another peptides and enzymes. In every live organism it acts as a sensitive rate of susceptibility to oxidative stress and its concentration in each organ and cell shows the level of their damage. Determination of glutathione using chromatographic methods has been a complement and many a time is also an alternative to different widely used methods, such as: enzymatic, spectrophotometric, spectrofluorometric, electromigrative, chemiluminescence, nuclear magnetic resonance. The most important steps in the sample preparation process for analysis are: amino thiols protection from high temperature and oxidation caused by substances from matrix, precipitation, reduction of disulfides and also derivatization (except for in vivo assays and those based on electrochemical and tandem mass spectrometry). Several methods have been presented in order to identify and quantify glutathione forms in human biological samples such as liquid chromatography with electrochemical, UV, fluorometric, mass spectrometric detection capillary electrophoresis and gas chromatography with mass spectrometry. This review presents different techniques for glutathione routine analysis in hospitals and also useful in clinical researches with large groups of patients.

    Opis:
    Celem niniejszej pracy było określenie, czy krenoterapia (kuracja pitna) za pomocą wód siarczkowo- siarkowodorowych słonych (WSSS) pochodzących z ujęcia "Zuzanna" z okolic Buska-Zdroju ma wpływ na zmianę stężenia glutationu (GSH i GSSG) we krwi pełnej. WSSS zawierają nie mniej niż 1 g związków siarki ogólnej w kilogramie wody leczniczej, a ich działanie zależy nie tylko od zawartości związków siarki, ale także od rodzaju i zawartości innych biopierwiastków. Liczne badania potwierdzają korzystny wpływ H2S na parametry antyoksydacyjne organizmu. W analizie stężenia GSH i GSSG we krwi wykorzystano metodę elektroforezy kapilarnej z detektorem UV. Badaniu poddano grupę 40 ochotników, zarówno kobiet jak i mężczyzn, w różnych przedziałach wiekowych. Kuracja za pomocą WSSS trwała 2 tygodnie. Otrzymane wyniki badań potwierdzają, że H2S występujący w WSSS zwiększa stężenie glutationu we krwi, a także dają uzasadnienie dla wykorzystywania krenoterapii w lecznictwie.
    The objective of the study was to agree whether crenotherapy (drinking therapy) with sulfide/hydrogen sulfide (SHS) waters from "Zuzanna" spring located in the area of Busko-Zdrój leads to increasing of glutathione (GSH and GSSG) content in human blood. SHS waters contain at least 1 g of total sulfur per kilogram of water and a treatment effect also depends on other bioelements. A lot of earlier experiments confirmed positive influence of H2S on antioxidative properties of organism. The method employing capillary electrophoresis with UV detector for the analysis of glutathione in human blood was developed. The group of 40 volunteers consisted of both women and men, in different age range. The therapy with SHS waters lasted 2 weeks. We recently demonstrated that the administration of H2S in SHS waters increases GSH concentration in blood, and therefore crenotherapy could be used in therapeutics.
