    Opis:
    Objectives The aim of this study has been to evaluate the rate of contact sensitization to some rubber allergens and to bisphenol A (BPA) amongst students of dental medicine and dental patients. Material and Methods A total of 50 participants were included in the study: 40 students of dental medicine exposed to the studied rubber allergens and BPA-based dental materials during the course of their education; 10 dental patients without occupational exposure to the latter substances served as a control group. All of them were patch-tested with the studied rubber allergens and bisphenol A. Results Highest was the sensitizing action of carba mix, followed by benzoyl peroxide and mercapto mix. The sensitization rate for carba mix was significantly higher for dental students as well as for the whole studied population, if compared to the one for thiuram mix (Chi² = 12.9, p < 0.001; Chi² = 13.9, p < 0.001), bisphenol A (Chi² = 8.9, p < 0.001; Chi² = 11.9, p < 0.001), toluenesulfonamide formaldehyde resin (Chi² = 10.7, p < 0.001; Chi² = 13.9, p < 0.001) and benzoyl peroxide (Chi² = 4.7, p = 0.03; Chi² = 5.8, p = 0.016), and for dental patients, if compared to the one for mercapto mix (Chi² = 7.07, p = 0.008). Concomitant positive skin patch-test reactions to carba mix and to benzoyl peroxide, and to all the studied allergens were established. Conclusions Carba mix could be outlined as a sensitizer of paramount importance for dental students as well as for dental patients. Benzoyl peroxide was the second ranked sensitizer for dental students. Positive skin patch-test reactions to bisphenol A and toluenesulfonamide formaldehyde resin were established only among the group of dental students. Int J Occup Med Environ Health 2017;30(3):397–405

    Opis:
    The objective of these studies was to identify differences and similarities within the progeny of Rhizoctonia solani AG5, which arose from basidiospores produced by the maternal strain ID23. The following characteristics were analyzed: appearance of the mycelium (color, structure, zonation, and presence of sclerotia), growth rate (at 10°C, 20°C, and 30°C), fungicide sensitivity, and hyphal structure. The mycelial color of R. solani AG5 ranged from white/cream to light and dark brown. The structure of the mycelium may be compacted or flattened with visible zoning or fluffy with dark brown sclerotia on the colony surface. Homokaryons and heterokaryons derived from homokaryons were analyzed by constructing a phylogenetic tree using morphological data. Single basidiospore-grown isolates formed a separate subclade, the majority of which were grouped with a maternal isolate; however, heterokaryons derived from them created a separate subclade. In addition, isolates grown in basidiospores germinated at low temperatures created their own group, but with some exceptions. This shows a divergence in the morphological parameters of the subsequent generations and within generations. The optimal temperature for growth was found to be between 20°C and 30°C. The exceptions were strains obtained from basidiospores that germinated at refrigerated temperatures. For these samples, 10°C was found to be the optimal growth temperature. The hyphae of homokaryons were characterized by the presence of branching at an almost right angle and the presence of a septum at the site of constriction of the branch itself. The mean diameter of hyphae ranged 2.93–15.60 μm, depending on the age of hyphae. The fungicidal compounds at a concentration of 10 ppm had no significant effect on the activity of the tested strains, whereas a tenfold increase in the dose reduced the growth ability of the tested isolates. The activity of fungicides containing azoxystrobin, thiuram, or thiophanate-methyl on R. solani resulted in a reduction in the mycelial growth rate only in the case of azoxystrobin and thiuram, and in some cases, it was completely inhibited (thiophanate-methyl).

    Opis:
    Soybean seeds (cv. Aldana) were treated with a synthetic seed dressing composed of carboxin (20%) and thiuram (20%) as the active ingredients or with a natural fungicidal preparation containing 23.8% of natural oil extracted from tea tree, and next day untreated (control) and treated with the above mentioned preparations soybean seeds were pelleted with inoculant containing Bradyrhizobium japonicum – the symbiotic bacterium of this plant. Shortly (within 1–2 hours) after seed inoculation and after 24 hours of storing the inoculated seeds at room temperature seed samples were collected to count rhizobial numbers on seeds. At the same sampling times seeds were also sown into pots filled with perlite moistened with water solution of plant nutrients (without N). After 4 weeks of plant growth in a growth chamber numbers of root nodules were counted and fresh and dry mass of shoots were determined. The studied chemical seed dress- ings had no significant effects on numbers of soybean rhizobia on seeds, and on nodulation and growth of soybean plants when seeds were analyzed or planted shortly after their inoculation with B. japonicum. However, the studied preparations significantly reduced numbers of soybean rhizobia on seeds stored for 24 h at room temperature, but only the synthetic one affected adversely nodulation and some growth parameters of soybean plants that developed from the stored seeds
