Opis:: ObjectivesVarious indirect or direct airway challenge tests are used to measure nonspecific bronchial hyper-responsiveness (NSBHR). The evaluation of NSBHR in diagnosing occupational asthma (OA) is performed, e.g., to monitor the specific inhalation challenge test (SICT). The aim of this study was to preliminarily compare the results of methacholine and mannitol inhalation challenge tests in SICT monitoring in bakers with work-related airway symptoms.Material and MethodsFour bakery workers with a suspicion of OA underwent single-blind placebo-controlled SICTs involving workplace allergens, accompanied by the evaluation of NSBHR with mannitol and methacholine, both before and after SICTs. Clinical examinations, spirometry tests, skin prick tests (SPTs) to common aeroallergens and occupational allergens, as well as tests to determine serum specific IgE antibodies to occupational aeroallergens were also performed.ResultsPositive SPTs results to occupational aeroallergens were found in all bakery workers, and specific IgE antibodies to flour were detected in 2 subjects. Three patients displayed positive SICT reactions. In all of these 3 patients, airway responsiveness to methacholine increased significantly. In 2 patients, airway reaction to mannitol was significant, whereas in 1 subject there was no increase in NSBHR after mannitol inhalation. The patient with a negative SICT result did not reveal any changes in NSBHR before and after the test, either to methacholine or mannitol.ConclusionsThe data obtained by the authors show that there is no clear correlation between the methacholine and mannitol inhalation challenge tests in SICT monitoring. Preliminary results indicate the need for further investigations to evaluate the usefulness of the mannitol challenge test in the diagnostics of OA.

Opis:: The aim of the work was to determine how the induction of androgenesis in selected genotypes of Salix viminalis is affected by thermal factors and medium composition. Anthers isolated from male clones of S. viminalis were pre-cultured at 4, 27 and 32°C for two to eight days in liquid Kyo medium with and without the addition of mannitol and on solid MS or WPM medium. The solid media were supplemented with different concentration of disaccharidesand various combinations of growth regulators including kinetin, 2iP, IAA and IBA. Multi-nucleate microspores indicative of androgenesis were observed in anthers pre-cultured for seven days at 4°C in liquid Kyo medium containing mannitol. The rate of androgenesis was higher when the anthers were transferred to solid modified MS medium containing high concentrations of sucrose and kinetin. In studied genotypes of basket willow early uninucleate microspores underwent sporophytic divisions. Ultrastructural observations showed differences in cellular arrangement of pre-stressed microspores. In Salix viminalis, microspores without starch grains and decreased number of lipid bodies were potentially androgenic cells.

Tytuł:: Genotypic variation in response to iso-osmotic and soil moisture stresses among old and modern cultivars of winter wheat

Opis:: The study was performed to evaluate range of the genotypie variation in drought susceptibility at juvenile growth stages among 23 old and modern winter cultivars of Triticum aestivum and one old cv. of T. spelta. Response of germinated seeds to mannitol-simulated drought stress as well as that in seedling shoot and root growth, water use and leaf transpiration under varied soil moisture were measured. Considerable genotypie variation for all morpho-physiological traits was found between wheat cultivars. There were significant differences between the older and modern cultivars. The former showed usually an enhanced rooting ability and higher water requirements, while the newer indicated more efficient water use. The older cultivars were more resistant to both iso-osmotic stress and low soil moisture at the juvenile growth stage. However, no clear differences were found between the two groups of cultivars in the variation range of the drought susceptibility indices. Complex patterns of the response to drought were observed. Cultivars, which distinguished by both a lower shoot : root ratio and a stronger drought-induced stimulative root growth, tended to be more resistant. Although only moderate the relationships noticed, a consideration of the root plasticity screening in local wheat breeding appears to be justified.

Opis:: The aim of research was the elaboration of the synthesis of new organic monomer applicable in gelcasting. The substance named 3,4-di-acryloyl-D-mannitol which contains two acryloyl groups and four hydroxyl groups in its molecule has been synthesized. The monomer has been then applied in the preparation of Al₂O₃-ZrO₂ composites by gelcasting and subsequent sintering. Rheological properties of ceramic suspensions have been examined, as well as the properties of green and sintered bodies. SEM observations allowed to determine the distribution of zirconia grains in alumina matrix. Density, Vickers hardness and fracture toughness of ZTA composites have been measured. The new monomer, that is diacryloyl derivative of mannitol, is less sensitive to the oxygen inhibition than commonly used in gelcasting and commercially available 2-hydroxyethyl acrylate.

Opis:: The aim of the research was to assess the androgenic potential of 21 Polish cultivars of spring and winter barley. On average, a few green plants developed per 100 anthers. Cold pretreatment proved conducive to the formation of embryos/calli, while mannitol pretreatment favoured green plant development. The first embryos/calli formed on the induction medium developed most efficiently. The authors chose FHG medium supplemented with 1 mg/l BAP and 0.2 mg/l 2,4-D (induction of androgenesis) and FHG medium supplemented with 0.4 mg/l BAP and 3% maltose (plant development).
