Opis:: Iron is a trace element involved in many cardinal metabolic processes of almost all living organisms. It is well known that iron participates in oxygen transport as well as it is a cofactor in many fundamental enzymatic and nonenzymatic processes. Accordingly, disturbances of iron homeostasis can cause serious clinical consequences. In humans, dietary iron can enter the body in two main forms: heme and nonheme. The former is a component of many hemoproteins (including myoglobin, hemoglobin, cytochromes b and c) and is easily absorbed in the duodenal enterocytes. Red meat is an excellent source of heme iron, while the less bioavailable nonheme form is found in large amounts in milk products and vegetables. For this reason, consumers of meat have a better iron status than vegetarians and vegans. The aim of this paper was to discuss the role of heme iron in the human diet. Heme iron found in muscle protein should be supplied to humans to prevent iron deficiency, which can lead to anemia. It is easily absorbed by the human body and its main source is red meat. In addition, heme iron, which is mainly found in myoglobin in meat, contributes to the desirable bright red color and to the most undesirable brown color of meat. Both heme and nonheme iron are catalysts of lipid oxidation in meat. This process lowers the nutritive value through oxidation of polyunsaturated fatty acids, which produces an undesirable flavor and aroma. The present review is focused on the role of heme iron, which is mainly found in meat and is the principal source of iron in the human diet.

Opis:: Dwa chińskie preparaty bionawożeniowe Juwei i C. B. I. uruchamiające K i P z minerałów glebowych przebadano pod względem przeżywalności zawartych w nich aktywnych mikroorganizmów podczas przechowywania i po wprowadzeniu do gleby opłaszczonych C. B. I. nasion. Po 10 miesięcznym okresie przechowywania liczebność aktywnych bakterii w Juwei obniżyła się o 1 rząd wielkości. Nie stwierdzono zmian w liczebności bakterii rozpuszczających fosforany wapnia i potasu w glebie po wprowadzeniu opłaszczonych biopreparatem nasion rzodkiewki. Liczebność bakterii uruchamiających fosfor i potas stwierdzona na jednym ziarnie kukurydzy opłaszczonym preparatem C. B. I., była 10-krotnie wyższa niż liczebność takich bakterii występująca w 1 gramie suchej gleby użytej w doświadczeniu. Badane biopreparaty były barwy czarnej, wyglądem przypominały mursz i wykazywały lekko kwaśny odczyn. Pod względem składu chemicznego biopreparat C. B. I. zawierał więcej materii organicznej, ogólnego potasu, magnezu i wapnia i mniej przyswajalnego i ogólnego fosforu niż preparat Juwei. Nie stwierdzono w nich natomiast substancji szkodliwych (metale ciężkie, pestycydy chloroorganiczne i PCB) w ilościach zagrażających funkcjonowaniu środowiska glebowego.
Two Chinese biofertilizers: Juwei and C. B. I. mobilizing K and P from soil minerals were tested with respect to survival of contained in them active microorganisms during storage and after their introduction into soil as seed dressing. After long-term storage the number of active microorganisms in Juwei decreased by 1 order of magnitude. There was no increase in the number of bacteria solubilizing potassium and calcium phosphates in the soil after introduction of small seeds (radish) dressed with C. B. I. However, the number of these bacteria found on bigger seed (maize) dressed with C. B. I. was 10-times higher than that occuring present in 1 g dry soil used in the experiment. Both examined biofertilizers (Juwei and C. B. I) looked like a muck and were characterized by black colour and slightly acid reaction. The C. B. I. biofertilizer contained much more organic matter, total potassium, magnesium and calcium, whereas the contents of available and total phosphorus were substantially lower in comparison to the Juwei biofertilizer. In any biofertilizer no harmful substances (heavy metals, chloroorganic pesticides and PCB) were found in the amounts which could threaten the functioning of soil environment.

Rok 2019 był przełomowy w kwestii dostępności ziela konopi dla polskich pacjentów. Po trzech miesiącach od zarejestrowania na rynek trafił pierwszy preparat suszu konopi. Fakt ten stworzył nowe możliwości terapii dla pacjentów. Postawił również nowe wyzwania dla farmaceutów. O niegasnącym zainteresowaniu terapeutycznego zastosowania Cannabis sativa świadczy ogromna ilość publikacji dotyczących farmakologicznych właściwości składników konopi oraz bardzo licznie prowadzone badania kliniczne. Celem pracy było przybliżenie praktycznych aspektów obecności suszu konopnego w polskich aptekach.

Opis:: Intraspecific changes in genome size and chromosome number lead to divergence and species evolution. Heavy metals disturb the cell cycle and cause mutations. Areas contaminated by heavy metals (metalliferous sites) are places where microevolutionary processes accelerate; very often only a few generations are enough for a new genotype to arise. This study, which continues our long-term research on Viola tricolor (Violaceae), a species occurring on both metalliferous (Zn, Pb, Cd, Cu) and non-metalliferous soils in Western and Central Europe, is aimed at determining the influence of environments polluted with heavy metals on genome size and karyological variability. The genome size of V. tricolor ranged from 3.801 to 4.203 pg, but the differences between metallicolous and non-metallicolous populations were not statistically significant. Altered chromosome numbers were significantly more frequent in material from the polluted sites than from the non-polluted sites (43% versus 28%). Besides the standard chromosome number (2n = 26), aneuploid cells with lower (2n = 18–25) or higher (2n = 27, 28) chromosome numbers were found in plants from both types of site, but polyploid (2n = 42) cells were observed only in plants from the metalliferous locality. The lack of correlation between chromosome variability in root meristematic cells and genome size estimated from peduncle cells can be attributed to elimination of somatic mutations in generative meristem, producing chromosome-stable non-meristematic tissues in the peduncle.

Opis:: The study was designed to determine the proper conditions for suspension culture of Viola tricolor cells in toxicity studies of Pb at different concentrations (0, 200, 500, 1000, 2000 μM) and exposure times (24, 48, 72 h). By forming insoluble salts with ions from the medium, lead (II) nitrate added to the medium decreased the initial 5.7–5.8 pH of the medium, depending on the Pb salt concentration and light intensity. In alamarBlue assays, we found no dose- or time-dependent effect of Pb on cell viability when we did not adjust pH and did not standardize the illumination conditions to correct the effect of lead-salt-induced turbidity. When effective illumination was adjusted to correct for turbidity at the highest lead concentration and pH was adjusted to 5.7–5.8, cell viability decreased with the increase of Pb(NO₃)₂ concentration and with treatment time. These experiments demonstrate that the toxic action of lead on cells in suspension depends strongly on culture conditions, and not only on the metal concentration and duration of treatment.

Opis:: Na glebie lekkiej typowej dla Pomorza Zachodniego przeprowadzono doświadczenia poletkowe nad efektywnością chińskiego biopreparatu „JUWEI” CBI do stymulowania wzrostu kukurydzy (2002 - 2004) i ziemniaków (2003 - 2005). Preparat ten zawiera dwa szczepy bakterii z rodzaju Bacillus, charakteryzujące się między innymi zdolnością do rozpuszczania fosforanów nieorganicznych (B. megatherium i B. mucilaginosus) i wiązania N₂ (B. mucilaginosus). Biopreparat zastosowano zgodnie z zaleceniami producenta. Gleba na poletkach pod testowanymi roślinami różniła się właściwościami fizykochemicznymi, zwłaszcza pHKCl (4,9 - 7,1), zawartością dostępnego P (4,9 - 24,5 mg·100 g⁻¹) i K (7,5 - 12,3 mg·100 g⁻¹), ogólną zawartością C (0,67 - 0,91%) i N (0,06 - 0,20%), lecz zawierała wysoką i zbliżoną liczebność bakterii rozpuszczających fosforany i wiążących N₂ (1·10⁷·g⁻¹ s.m. gleby). Nie stwierdzono statystycznie istotnego zwiększenia plonów testowych roślin, zawartości w nich P i K oraz zawartości w glebie dostępnego P i K w poszczególnych latach pomimo zróżnicowanych właściwości fizykochemicznych gleby pod uprawami. Analizy mikrobiologiczne wykazały, że zarówno w glebie wolnej od korzeni, jak też w strefie korzeniowej roślin na poletkach traktowanych „JUWEI” CBI nie zwiększyła się liczebność mikroorganizmów o cechach fizjologicznych szczepów wprowadzonych z biopreparatem. Uzyskane wyniki sugerują, że brak efektywności biopreparatu można wiązać ze zbyt niską liczebnością bakterii wprowadzonych do gleby z opłaszczonymi nim ziarniakami i bulwami. Przy zajętej niszy ekologicznej przez szczepy rodzime, nie miały szans na zasiedlenie i rozwój.
Biofertilizer „JUWEI” CBI containing two bacteria, Bacillus megatherium and B. mucilaginosus, capable to mobilizing phosphate and potassium from soil minerals and fixing N₂ has been manufactured in China since 1988. Field experiments conducted by Agricultural Institutes in Gaocheng and Langfang prefectures during 1990 - 1993 showed that after application of biofertilizer the average yields of grain crops and vegetables increased by 10% and by 20 - 30%, respetively. Plot experiments on the effect of „JUWEI” CBI (used according to the manufacture’s instructions) on the growth and yielding of maize and potato were conducted during 2002 - 2004 and 2003 - 2005, respectively, at Lipnik Experimental Station, Agricultural University of Szczecin. Physico-chemical properties of the soil on plots planted with tested plants differed in regard to pHKCl values (4.9 - 7.1), content of available P (4.9 - 24.5 mg·100 g⁻¹ soil) and K (7.5 - 12.3 mg·100 g⁻¹ soil), total content of C (0.67 - 0.91%) and N (0.06 - 0.20%). However, the number of bacteria capable to mobilizing P and fixing N₂ isolated from the soil were high (1·10⁷·g⁻¹ soil DM) and there was no significant differences between the plots. Statistical data analysis indicated that the treatment of plants with biofertilizer did not affect the yield, concentration of available P and K in soil, or the concentration of these elements in plant tissues. Microbial analysis of root-free and rhizospheric soil showed that there was no difference in the number of bacteria of the same phenotype as the bacteria introduced with biofertilizer between the soil sampled from control plots and that treated with „JUWEI” CBI. Lack of the biofertilizer „JUWEI” effectiveness could be due to a low number of microorganisms introduced with it into soil. The organisms had no chance to proliferate in the soil used to experiments, because their ecological niche had already been occupied by native microorganisms.

Opis:: Pollen and achene characters of natural interspecific hybrid Solidago ×niederederi Khek were analyzed and compared with putative parental species S. virgaurea L. and S. canadensis L. to estimate the level of disturbances in generative reproduction resulting from its hybrid nature. Pollen viability (stainability) of Solidago ×niederederi from one newly discovered locality in NE Poland was evidently reduced to ~65% in both viability tests (acetocarmine and Alexander). The diameter of viable pollen (median 21.11 μm) fell between S. canadensis (median 19.52 μm) and S. virgaurea (median 23.48 μm). Both parental species produced normally developed achenes with high frequency (~90%) whereas in the hybrid, the seed set was dramatically low (6%). The results clearly indicated that sexual reproduction of hybridogenous taxon S. ×niederederi is disturbed, and its potential impact as an invasive species depends mainly on vegetative propagation.

Opis:: Viola uliginosa (bog violet) is a declining species throughout its range due to – mostly anthropogenic – drying out of the wet habitats it occupies. Using AFLP markers, we aimed to estimate the genetic diversity in Polish populations, that may give an insight into the situation of plant populations facing rapid loss of natural habitats. Bog violet from several dispersed Polish populations is generally characterized by very low genetic diversity (HT = 0.048), even lower than several other endangered violets; therefore, we suggest that it should preserve at least EN rank in the red lists/red data books. The mean gene diversity within all populations (HS) was much lower than gene diversity (GST) between populations (0.020 versus 0.583, respectively) which supports the prevalence of clonal propagation of the species (mainly by stolons) but may also point to some significance of autogamy in cleisto- and chasmogamous flowers. A high FST value and the Mantel test for all populations revealed significant isolation by distance. Geographically neighboring pairs of populations formed genetic clusters supported by all (in the case of two closest populations) or most statistical analyses applied. Special attention should be paid to the locus classicus of the species in Rząska, consisting of a small number of individuals, forming a genetically distinct group, revealing very low gene diversity (Hj = 0.009) and the longest genetic distance to the remaining populations. Our results can contribute to planning future protection measures for the species at this and other locations. Genetic structure of the studied populations suggests local affinities of populations but does not generally support hypothesized recent continuity of V. uliginosa range along the river valleys of southern Poland; this view may, however, be altered with widening of the scope of studied populations and chosen molecular markers.

Opis:: We used different tests to assess the effect of high soil concentrations of heavy metals on pollen viability in plants from metallicolous (MET) and nonmetallicolous (NONMET) populations. The frequency of viable pollen depended on the test applied: MET plants showed no significant reduction of pollen viability by acetocarmine, Alexander, MTT and X-Gal dye testing, but a drastic reduction of pollen viability in MET flowers (MET 56% vs 72% NONMET) by the FDA test. There was no correlation between pollen viability estimated in histochemical tests and pollen germination in vitro or in vivo. We discuss the terminology used to describe pollen viability as determined by histochemical tests.
