Opis:
The examinations were performed in 129 patients; hepatomegaly was found in 50 cases; in 2 cases, post-mortem examinations showed in one case steatosis hepatis, in the other hepar muschatum. Laboratory examinations revealed variations in the level of blood serum bilirubin in the limits of 0.34-1.3 mg%; moreover, the majority of persons showed shortening of Weltmann's band, increase in GPT (80-682 units), aldolase activity (20-200 units) and a rise in quinine oxydase value. In some cases there was an increase in GOT, but mostly its value was normal. In some cases ceroplasmine level was also enhanced ; the pseudocholesterinase level of the blood serum was mostly decreased; the alcaline phosphatase activity showed, as a rule, no abnormalities, whereas serum catalase activity exhibited dyscatal asemia. In the authors' opinion, these findings indicate an incipient damage to the liver parenchym in patients with trichinellosis.

Within 12 years among 21.024 patients hospitalized in the Clinic of Infectious Diseases of the Medical Academy parasitoses were recognized in 485, i.e. 2.3%. The numbers testify to the importance of the problem of parasitoses in that region of Poland. The most frequent parasitoses of the Białystok region are at present giardiasis and taeniasis, most of all in inhabitants of towns, and within the last years also diseases introduced from the tropics - amebiasis, malaria and intestinal trematodosis.

Opis:
Aconitum lasiocarpum (Carpathian endemic) and A. variegatum (European endemic) occur sympatrically in the Polish Western Carpathians. Here their taxonomic hybrid A. ×pawlowskii occurs. The aim of this study was to determine the relationship between the taxonomic (Linnaean approach) and genetic structure (PCR-ISSR analysis) of the populations and individuals in two allopatric and four sympatric populations. We determined 309 individuals (OTUs) to species, subspecies and nothospecies using the Linnaean system of classification, and then genetically fingerprinted 39 randomly chosen OTUs. Comparison of the Nei and Li distances obtained from ISSR and morphological matrices using the Mantel test indicated a significant correlation (n = 39, r = 0.53, P = 0.001). Genetic analysis (NEWHYBRIDS) pointed to 7 OTUs as being later-generation hybrids (B1 introgessants) in the sympatric area. Five of them belong to A. variegatum, indicating cryptic introgression, and two belong to A. ×pawlowskii. Nonmetric multidimensional scaling (NDMS) showed gene flow between A. lasiocarpum and A. ×pawlowskii. Allopatric, morphologically pure A. lasiocarpum and A. variegatum populations differed significantly in their ISSR profiles (Fischer's R×C test, P < 0.0001). Expected heterozygosity (Hj) was significantly (p=0.05) lower in allopatric (0.1261–0.1268) than in sympatric populations (0.1348–0.1509), indicating a genetic melting pot in sympatry. The results support the existence of a natural interspecific hybrid swarm zone in the sympatric area of occurrence of Aconitum, and the taxonomic circumscription of the nothospecies within the Linnaean taxonomic system.

Opis:
Mając na uwadze wzrost zanieczyszczenia środowiska naturalnego metalami ciężkimi i ich oddziaływanie na mikroorganizmy w glebie, podjęto próbę określenia wpływu wybranych metali ciężkich: miedzi, kadmu, cynku i ołowiu na wzrost promieniowców wyizolowanych z gleb pobranych z terenu huty ArcelorMittal w Krakowie. Do badań wykorzystano 5 gleb, z których do dalszych badań wyselekcjonowano 10 izolatów promieniowców należących do rodzaju Streptomyces. Przeprowadzone analizy wykazały, że obecność huty przyczynia się do zanieczyszczenia środowiska glebowego poprzez emisje metali ciężkich. Ma to wpływ także na populację promieniowców w glebie nie tylko poprzez ograniczenie ich liczebności, lecz również poprzez selekcję szczepów opornych na zanieczyszczenia gleb, a przez to na ograniczenie ich bioróżnorodności. Pośrednim skutkiem ograniczenia różnorodności promieniowców może być wyginięcie szczepów ważnych pod względem funkcjonalnym dla środowiska, zubożenie mikroflory gleby, a także zmiany właściwości fizykochemicznych gleby. Niniejsza praca pokazuje, że skażenie środowiska metalami ciężkimi jest poważnym problemem środowiskowym. Zjawisko to należy monitorować i kontrolować, aby zapobiec nieodwracalnym zmianom w ekosystemie.
People have changed their environment since the beginning of the civilization - it is an inevitable process. However, this phenomenon is accompanied by emission of many harmful chemicals to the environment, and recently there has been an increase in the amount of pollution. Having regard to the increase in environmental contamination with heavy metals due to the expanding industry and its impact on soil microorganisms, this study attempted to determine the effect of the selected heavy metals: cadmium, copper, lead and zinc, on the growth of actinobacteria (belonging to the genus Streptomyces) isolated from soils of ArcelorMittal steelworks in Cracow. Five soil samples were selected for the analysis, from which 2 isolates of Streptomyces spp. were selected for further analyses. The number of Streptomyces spp. in the soil samples was determined using the serial dilutions method. The systematic affiliation of microorganisms was confirmed by macroscopic as well as microscopic observations of Gram-stained smears, catalase reaction test and the sequencing of 16S rDNA region. Additionally, soil physical and chemical properties were examined - pH, moisture and heavy metal content - using atomic spectrometry. The heavy metal resistance of the examined Streptomyces spp. strains was analyzed using a well method with increasing concentrations of cadmium, copper, lead and zinc. After the incubation results were recorded as the growth inhibition zones (diameters) and the minimum inhibitory concentration (MIC) of the heavy metals were determined. The conducted analyses revealed that heavy metal concentrations in two out of five examined soils exceeded the admissible values given by the Regulation of the Minister of Environment on soil quality standards. The number of actinobacteria in soils was varied (from 6700 to almost 250 thousand CFU per gram of soil dry weight). There was a negative correlation between the heavy metal concentrations in soils and the number of the studied microorganisms. The analyzed soils were alkaline - the lowest pH value was 7.7. Regarding the heavy metal resistance of the analyzed Streptomyces spp. strains, diverse in vitro susceptibility was recorded. The bacterial reactions differed even between strains isolated from the same soil samples. Minimum inhibitory concentrations of the examined heavy metals were as follows: Cd and Cu - 100 μg • cm−3, Zn - 3000 μg • cm−3 and Pb - 8000 μg • cm−3. There was a negative correlation between the concentration of heavy metals in soils and the growth inhibition zones (in the case of cadmium this correlation was high), indicating that the soil contamination with cadmium may have modified the soil population of Streptomyces spp., causing extinction of the susceptible strains while the ones with reduced sensitivity survived. The results of the presented research indicated that the ArcelorMittal steelworks contaminates the soil environment, which may affect the microbial community of soils, not only by reducing the population, but also by decreasing biodiversity of soil microorganisms, which was particularly visible in the case of cadmium - a strongly toxic heavy metal. This study demonstrates that the heavy metal contamination is a serious environmental problem. This phenomenon needs to be monitored and controlled to prevent irreversible changes to the ecosystem.

Opis:
Phylogenetic relations within Aconitum subgen. Aconitum (Ranunculaceae) in Europe are still unclear. To infer the phylogeny of the nuclear (ITS) region and chloroplast intergenic spacer trnL(UAG)-ndhF of the chloroplast DNA (cpDNA), we analyzed 64 accessions within this taxon, 58 from Europe and six from the Caucasus Mts. Nuclear ITS sequences were identical in 51 European and two Caucasian accessions, whereas the remaining sequences were unique. cpDNA sequences could be categorized into five haplotypes, i.e., A–E, including a European-Caucasian Aconitum haplotype B. Ten cpDNA sequences were unique. A 5-bp indel distinguished the diploids from the tetraploids. None of the extant European diploids were basal to the tetraploid local group. A phylogenetic tree based on combined ITS and cpDNA sequences (bayesian inference, maximum likelihood, minimal parsimony) placed Aconitum burnatii (Maritime Alps, Massif Central) and A. nevadense (Sierra Nevada, Pyrenees) in a sister group to all other European species. A Bayesian relaxed clock model estimated the earliest split of the Caucasian species during the Late Miocene [ca. 7 million years ago (Mya)], and the divergence of A. burnatii and A. nevadense from the European genetic stock during the Miocene/Pliocene (ca. 4.4 Mya). Diploids in Europe are likely to be descendants of the Miocene European-Caucasian flora linked with the ancient Asian (arctiotertiary) genetic stock. The origins of the tetraploids remain unclear, and it is possible that some tetraploids originated from local, now extinct diploids. Both the diploids and tetraploids underwent rapid differentiation in the Late Pliocene – Quaternary period.

Opis:
The genetic diversity of two Aconitum species endemic to the Carpathian Mountains and Sudetes was studied. A reticulate evolution between them was earlier postulated as an effect of secondary contact. The genetic diversity at the individual and taxonomic levels was examined across the entire geographical ranges of the taxa in 11 populations based on 247 AFLP markers found in 112 individuals in the Sudetes and Western Carpathians. The overall genetic differentiation was greater within the Sudetic A. plicatum (Fst = 0.139, P < 0.001) than within the Carpathian A. firmum (Fst = 0.062, P < 0.001), presumably due to the long-lasting geographic isolation between the Giant Mts and Praděd (Sudetes) populations of the species. Interestingly, relatively distant and presently isolated populations of A. plicatum and A. f. subsp. maninense share a part of their genomes. It could be an effect of their common evolutionary history, including past and present reticulations. The introgression among infraspecific taxa of Aconitum is common, probably as a result of seed dispersal within a distance of ca. 20 km (Mantel's r = 0.36, P = 0.01). Aconitum f. subsp. maninense had the highest genetic diversity indices: Nei's h and rarefied FAr, and divergence index DW (P < 0.05), pointing to its presumably ancient age and long-term isolation.
