Abstract: Introduction:The pathogenesis of seborrheic dermatitis has not been fully elucidated. A number of anascogenic yeasts of Malassezia spp. appear to be involved in the intensity of the symptoms. The purpose of the study is to evaluate the levels of selected inflammatory cytokines, IL-2, IL-4, IFN-γ and TNF-α, in the serum after treatment with itraconazole.Material/Methods:Sixty-six subjects were enrolled in the study. The control group consisted of 30 participants (23 females and 7 males) without any clinical disorders, aged 24–65 (37.41±6.08 years). Thirty-six patients with seborrheic dermatitis (16 females and 20 males), aged 19–76 (38.61±13.77), constituted the study group. The measurement of IL-2, IL-4, IFN-γ and TNF-α levels was performed by ELISA using a Human High Sensitivity kit (Diaclone, France).Results:After six-week treatment with itraconazole administered daily at a dose of 200 mg using pulse therapy, there was remission of the disease or at least substantial clinical improvement in the patients with seborrheic dermatitis. The levels of IL-2 and IFN-γ cytokines in the study group were higher than in the control group. After the treatment the level of IFN-γ secretion in the male patients with seborrheic dermatitis significantly increased. The levels of the other studied cytokines did not significantly differ.Conclusions:The treatment with itraconazole had a beneficial effect on the clinical condition of the skin of the patients. IFN-γ is a cytokine whose secretion might affect the condition of the skin in seborrheic dermatitis.

Abstract: Introduction:The etiology of seborrheic dermatitis is not fully understood. It has been observed that a number of anascogenic yeasts of Malassezia spp. is related to the intensity of the symptoms. The aim of the study is to measure the concentration of selected inflammatory factors IL-2, IL-4, IFN-γ and TNF-α in the serum by an immunoenzymatic method, as well as to confirm the relationship between the studied factors and the clinical condition of the patients (sex, the intensity of skin lesions according to the Scaparro scale) and, finally, to compare the results with the control group.Material/Methods:The total number of subjects who participated in the study was 66. The control group (C) consisted of 30 volunteers (23 females and 7 males), with no clinical disorders, aged 24–65 (37.41±6.08 years). Thirty-six patients with seborrheic dermatitis (16 females and 20 males), aged 19–76 (38.61±13.77), made up the study group. The determination of IL-2, IL-4, IFN-γ and TNF-α was performed by ELISA using a Human High Sensitivity kit (Diaclone, France). Clinically, the intensity of the disease process was evaluated on the Scaparro et al. scale, as modified by Kaszuba.Results:We observed statistically significantly higher levels of IL-2 and IFN-γ in patients with seborrheic dermatitis compared to the control group.Conclusions:We conclude that seborrheic dermatitis is a dermatosis characterized by a cell type immune response with an important role of IFN-γ and IL-2.
Arbuscular mycorrhizal fungi (Glomeromycota) associated with roots of Ammophila arenaria growing in maritime dunes of Bornholm (Denmark)
Janusz Baszkowski,Beata Czerniawska
Acta Societatis Botanicorum Poloniae , 2011, DOI: 10.5586/asbp.2011.009
Abstract: 155 rhizosphere soil and root mixtures were collected from under Ammophila arenaria colonizing maritime dunes of the island Bornholm (Denmark) to determine arbuscular mycorrhizal fungi (AMF) of the phylum Glomeromycota co-existing with this plant. In the laboratory, each mixture was divided into two parts. One part was used to establish a pot culture with Plantago lanceolata as the host plant to initiate sporulation of fungi that had not produced spores in field conditions. In the second part, the numerical and species composition of the spore populations of AMF sporulating in the field was determined. Spores of AMF were found in 70 field-collected samples and 134 trap cultures. They represented 26 species and six undescribed morphotypes in six genera of the Glomeromycota. Of them, 20 species and three morphotypes in five genera occurred in the field, and 16 species and three morphotypes in five genera were found in trap cultures. The fungi most frequently revealed were members of the genus Glomus; a total of 17 species and six morphotypes of this genus were recognized. Considering the occurrence of spores in both field samples and trap cultures, the fungi most frequently co-occurring with roots of A. arenaria growing in the dunes of Bornholm were G. irregulare (present in 73.6% of samples), followed by Scutellospora dipurpurescens (19.4%) and Archaeospora trappei (10.3%). However, Glomus irregulare mainly sporulated in trap cultures; spores of this fungus were found in only 0.6% of field samples. Other relatively frequently found species were G. aggregatum (9.0%), G. eburneum (7.1%), Paraglomus laccatum (5.2%), and S. armeniaca (6.5%). The species most abundantly sporulating in the field were G. aggregatum (produced 28.36% of all spores isolated), G. badium (11.00%), and S. dipurpurescens (21.55%).

Acta Societatis Botanicorum Poloniae , 2000, DOI: 10.5586/asbp.2000.030
Abstract: In the years 1994-1995, the occurrence of arbuscular mycorrhizal fungi (AMF) and arbuscular mycorrhizae (AM) in eight successional stages of vegetation of a deflation hollow no. 12 of the eba Bar, Poland, was investigated. Early successional stages were colonized by members of the families Gramineae and Juncaceae, being gradually replaced by ericaceous plants in the middle and later stages and by trees in the most advanced stage corresponding to the Empetro nigri-Pinetum plant association. From the 96 soil samples collected, 21 species in three genera of AMF were recovered. The fungi most frequently found were members of the genus Acaulospora. The overall spore abundance, the species_ richness of AMF and the level of AM colonisation increased from stage 1 to reach a maximum in the middle stages and then gradually declined, being lowest in the forested stage 8. The values of the overall spore abundance and those of the abundances of the most frequently occurring AMF species strongly evidenced functioning in nature of the process of host-dependent differentiation of AMF communities. Of the five most numerously represented AMF species, the early colonizer and quickly diminishing in later successional stages was Glomus 107. The mid-late successor was A. koskei, and the latest - Glomus aggregatum. All measures of AMF presence negatively correlated with the content of organic C in the soil and most of them were negatively correlated with soil N-NO3 and P concentrations. In contrast, the occurrence of AMY and AM generally was positively correlated with soil pH and the K content of the soil.

Janusz Baszkowski,Beata Czerniawska
Acta Societatis Botanicorum Poloniae , 2006, DOI: 10.5586/asbp.2006.041
Abstract: In December 1997 and June-July 2000, 49 and 113 rhizosphere soil and root mixtures were collected, respectively, to determine the occurrence of arbuscular mycorrhizal fungi (AMF) of the phylum Glomeromycota in different sites of Israel. Except for five samples taken from under cultivated plants, all the others came from under Ammophila arenaria and Oenothera drummondii colonizing sand dunes adjacent to the Mediterranean Sea. After a continuous cultivation of the mixtures in pot trap cultures with Plantago lanceolata as the plant host up to 2006 and their examination at least twice a year, spores of AMF were found in 41 and 103 cultures with the 1997 and 2000 soil and root mixtures, respectively. The spores represented 30 species and 8 undescribed morphotypes in 7 genera of the Glomeromycota. The AMF most frequently found in Israeli soils were Glomus aurantium and G. constrictum, followed by G. coronatum, G. gibbosum, an undescribed Glomus 178, and Scutellospora dipurpurescens. Up to 2001, 21 species of AMF were known to occur in Israel, and this paper increases this number to 33, of which 11 are new fungi for this country. Moreover, four species, G. aurantium, G. drummondii, G. walkeri and G. xanthium, were recently described as new for science based on spores isolated from Israeli soils. Additionally, the general distribution in the world of the formally described species found in Israel was presented.

Szymon Zubek,Janusz Baszkowski,Piotr Mleczko
Acta Societatis Botanicorum Poloniae , 2011, DOI: 10.5586/asbp.2011.033
Abstract: Arbuscular mycorrhizal fungi (AMF) and dark septate endophyte (DSE) associations were studied in 36 medicinal plant species from 33 genera and 17 families, collected from the Botanical Garden of the Jagiellonian University in Kraków. Arbuscular mycorrhiza (AM) was found in 34 species (94%); 26 were of the Arum-type, 4 – Paris and 4 taxa revealed intermediate morpho-logy. The abundance of AMF hyphae in roots varied with particular species, ranging from 2.5% (Helianthus tuberosus) to 77.9% (Convallaria majalis). The mycelium of DSE was observed in 13 plant species (36%), however, the percentage of root colonization by these fungi was low. Spores of 7 AMF species (Glomeromycota) were isolated from trap cultures established from rhizosphere soils of the investigated plants: Archaeospora trappei (Archaeosporaceae), Glomus aureum, Glomus caledonium, Glomus claroideum, Glomus constrictum, Glomus mosseae, Glomus versiforme (Glomeraceae). Our results are the first detailed report of root endophyte associations of the plant species under study. Moreover, the mycorrhizal status of 14 plant species is reported for the first time.

Acta Societatis Botanicorum Poloniae , 2004, DOI: 10.5586/asbp.2004.011
Abstract: Morphological properties of sporocarps and spores of Endogone lactiflua (Zygomycota, Endogonales), a fungus for the first time found in Poland, are described and illustrated. Endogone lactiflua was wet sieved and decanted from a sample taken from the zone extending from the upper soil layer to rhizosphere of Pinus sylvestris growing in a forest dune in northern Poland. The recovered spores mainly occurred in large and compact sporocarps, although both small aggregates with a few spores and single zygosporangia of this fungus were also isolated. Endogone lactiflua is the fourth species of the genus Endogone found to occur in Poland. The distribution of the fungus in the world is also presented.

Acta Societatis Botanicorum Poloniae , 2001, DOI: 10.5586/asbp.2001.007
Abstract: Ustilago trichophora, a smut fungus found for the first time in Poland, is characterized and illustrated. Ustilago trichophora affected Echinochloa crus-galli growing in the Lower Silesia voivodeship. In laboratory investigations, the germinability of teliospores, the morphological properties of promycelium, sporidia and colonies produced on potato dextrose agar, Sabouraud-glucose agar, and in water were determined. Attempts to infect seeds and seedling of E. crus-galli in a greenhouse pot experiment failed.

Janusz Baszkowski,Mariusz Tadych,Tadeusz Madej
Acta Societatis Botanicorum Poloniae , 2002, DOI: 10.5586/asbp.2002.008
Abstract: The occurrence of arbuscular mycorrhizal fungi (AMF; Glomales, Zygomycetes) associated with plants growing in sand dune soils of the Bl dowska Desert, Poland, was investigated in 1995-1997. A total of 134 mixtures of soils and roots were sampled. The mixtures represented 26 plant species in 14 families and one unrecognized plant. Spores of AMF were found in 118 soil-root mixtures. The AMF spore populations comprised 20 described species of the genera Acaulospora, Gigaspora, Glomus and Scutellospora, as well as two undescribed morphospecies of the genus Glomus. The AMF most frequently occurring in the field-collected soils were members of the genus Scutellospora The AMF spore populations comprised 20 described species in the genera Acaulospora, Gigaspora, Glomus and Scutellospora, as well as two undescribed morpho-species of the genus Glomus. The fungal species most frequently and numerously found was Scutellospora armeniaca. The fungi relatively frequently present also were A. rugosa, A. lacunosa, G. aggregatum, an undescribed Glomus 142 and Sc. dipurpurescens. The overall spore abundance of AMF averaged 69.1 and ranged from 0 to 837 in 100 g dry soil. The highest abundance of spores occurred among roots of the families Cupressaceae, followed by the Rosaceae, Asteraceae and Poaceae. Of the plant species investigated two and more times, most spores harboured Juniperus communis. The overall average species richness was 2.4 and ranged from 0 to 6 in 100 g dry soil. Of the plant species sampled at lest two times, the highest average species diversity was found in the root zone of Salix arenaria. The plant species that hosted the highest overall number of species of AMF was Festuca rubra. Trap pot cultures with soilroot mixtures collected in 1997 revealed 10 species of AMF that were not found in field soils sampled in the same year. This suggests that a great part of AMF of B dowska Desert is represented by rarely or non-sporulating species.
