Opis:
The study analyses accident rate in the Regional Directorate of the State Forests in Szczecinek (NW Poland) in the years 1990−2009. 1042 accidents occurred in the analyzed period. The frequency rate equalled to 14.75, i.e. almost 15 accidents per 1000 employees. The severity rate amounted 48.65. The analysis showed that privatization of forest works did not have significant impact on accident rates.

Opis:
The present study consisted of two experiments. The goal of the first experiment was to establish the just noticeable differences for the fundamental frequency of the vowel /u/ by using the 2AFC method. We obtained the threshold value for 27 cents. This value is larger than the motor reaction values which had been observed in previous experiments (e.g. 9 or 19 cents). The second experiment was intended to provide neurophysiological confirmation of the detection of shifts in a frequency, using event-related potentials (ERPs). We concentrated on the mismatch negativity (MMN) - the component elicited by the change in the pattern of stimuli. Its occurrence is correlated with the discrimination threshold. In our study, MMN was observed for changes greater than 27 cents - shifts of ±50 and 100 cents (effect size - Cohen’s d = 2.259). MMN did not appear for changes of ±10 and 20 cents. The results showed that the values for which motor responses can be observed are indeed lower than those for perceptual thresholds.

Opis:
Introduction. Fungal keratitis is a severe condition which may lead to blindness. Fungal keratitis, also known mycotic keratitis or keratomycosis, has worldwide distribution, but is more common in tropical climates compared to moderate zones. In recent years, there have been several studies suggesting an increase in the number of mycotic keratitis cases in countries with a moderate climate. There is little data available with no literature review concerning fungal keratitis in European countries. Objective. To analyse the causes, presentation, and clinico-pathological associations of fungal keratitis in a retrospective series of patients referred to the Department of Ophthalmology of the Railway Hospital in Katowice, south-west Poland, and comparing the findings to previously published studies in peer reviewed articles from other European countries published between 2000–2019. Materials and method. Data were collected using the medical records of patients with fungal keratitis. Risk factors, clinical manifestation and treatment results were analysed from 45 patients (45 eyes) with fungal keratitis treated in the Department of Ophthalmology of Railway Hospital in Katowice between January 2013 – December 2017. The factors affecting the development of infection, visual acuity at baseline and at the end of treatment, as well as treatment method selection, were analysed. Literature review was performed using the Medline, Pubmed, Embase databases and Google scholar. The inclusion criteria were peer reviewed papers published between 2000–2019 which reported data from patients with fungal keratitis in at least one European country. 11 peer reviewed articles which matched the inclusion criteria were analysed. Results. The mean BCVA of patients treated in the Department of Ophthalmology of the Railway Hospital in Katowice upon diagnosis was 2.3 (logMAR), compared to 1.95 (logMAR) at the end of treatment. Pearson’s chi-squared test was used to establish the final mean BCVA in eyes with keratitis caused by Candida spp. compared with keratitis caused by Filamentous spp. The reviewed articles showed poor results of treatment and diagnostic difficulties in fungal keratitis. Conclusions. Fungal keratitis is a significant diagnostic and therapeutic challenge and may occur in rural and urban areas. Early and accurate diagnosis followed by proper antifungal treatment can prevent blindness and improve BCVA results.

Opis:
The zebrafish (Danio rerio) has become known as an excellent model organism for studies of vertebrate biology, vertebrate genetics, embryonal development, diseases and drug screening. Nevertheless, there is still lack of detailed reports about usage of the zebrafish as a model in veterinary medicine. Comparing to other vertebrates, they can lay hundreds of eggs at weekly intervals, externally fertilized zebrafish embryos are accessible to observation and manipulation at all stages of their development, which makes possible to simplify the research techniques such as fate mapping, fluorescent tracer time-lapse lineage analysis and single cell transplantation. Although zebrafish are only 2.5 cm long, they are easy to maintain. Intraperitoneal and intracerebroventricular injections, blood sampling and measurement of food intake are possible to be carry out in adult zebrafish. Danio rerio is a useful animal model for neurobiology, developmental biology, drug research, virology, microbiology and genetics. A lot of diseases, for which the zebrafish is a perfect model organism, affect aquatic animals. For a part of them, like those caused by Mycobacterium marinum or Pseudoloma neutrophila, Danio rerio is a natural host, but the zebrafish is also susceptible to the most of fish diseases including Itch, Spring viraemia of carp and Infectious spleen and kidney necrosis. The zebrafish is commonly used in research of bacterial virulence. The zebrafish embryo allows for rapid, non-invasive and real time analysis of bacterial infections in a vertebrate host. Plenty of common pathogens can be examined using zebrafish model: Streptococcus iniae, Vibrio anguillarum or Listeria monocytogenes. The steps are taken to use the zebrafish also in fungal research, especially that dealing with Candida albicans and Cryptococcus neoformans. Although, the zebrafish is used commonly as an animal model to study diseases caused by external agents, it is also useful in studies of metabolic disorders including fatty liver disease and diabetes. The zebrafish is also a valuable tool as a model in behavioral studies connected with feeding, predator evasion, habituation and memory or lateralized control of behavior. The aim of the present article is to familiarize the reader with the possibilities of Danio rerio as an experimental model for veterinary medicine.
