Opis:
Genetic research allows not only for precise diagnosing of diseases, but also for selecting therapy and appropriate medicines, and for insight into future health condition. Genetic information obtained as a result of genetic research is related not only to patients, but to their relatives, too. In this context a threat arises of abuse, infringement of human rights and unauthorised access to genetic data. The audit of NIK was aimed, in the first place, to examine whether genetic research in Poland is conducted with due care for safety requirements, that is whether Polish legal regulations keep up with the development of modern technologies in medicine.

Opis:
The medicinal plants of Jordan are under threat due to several factors of habitat perturbation. Some of these factors include ruinous over-harvesting, climate change, competition and invasion. In this study, the authors employed a reliable method for micropropagation and assessment of antimicrobial activity of some important medicinal plants of Jordan. Seeds were surface sterilized and germinated on agar water media, and then shoots were cultured on Murashige and Skoog (MS) medium with the addition of 3% sucrose. In order to generate enough plant material, microshoots were transferred after fourteen days onto hormone free MS medium. Among all studied plants, it was found that the Achellia millefolium and Moring perigrina plants successfully multiplied in vitro containing different 6-benzyl amino purine (BA). For potential antimicrobial activity, the ex vitro (field leaf plants) and in vitro (plantlet) extracts were evaluated against some bacteria strains using ethanolic extracts. Both ex vitro and in vitro plants extracts showed the antimicrobial activity against the microorganism tested. The results from the study suggest that these two plants showed good antimicrobial activity against the different tested bacteria.

Opis:
Background. During the recent years, appropriate attention has been paid to the oxidative stress which damages the body’s cells, proteins, and DNA. Therefore, the need of antioxidants becomes a therapeutic and preventive priority. In addition, microbial infections also constitute a public health problem. Objective. To find efficient, reliable and safe alternatives sources to synthetic antioxidants, antibiotics and antifungals drugs. Materials and methods. Extract and essential oil of Psidium guajava were screened for their antioxidant and antimicrobial activities against gram positive bacteria (Enterococcus faecalis and Staphylococcus aureus), gram negative bacteria (Citrobacter freundii, Escherichia coli and Pseudomonas sp) and fungi (Candida albicans,Candida tropicalis and Cryptococcus neoformans), as well as to determine the functional groups of phytochemicals present in the essential oil by Fourier transform infrared spectroscopy (FTIR). Results. The results indicate that P. guajava leaves extract demonstrated very high antioxidant activity and P.guajava essential oil showed the highest polyphenols content. The antioxidant capacity showed a significant negative linear correlation to total polyphenolic content (TPC) with Pearson’s correlation coefficients. P. guajava essential oil shows high antibacterial and antifungal activity against all the studied bacteria and fungi.The FTIR analysis of P. guajava essential oil showed the presence of several functional groups (ethers, esters, ketones, terpenes, alkanes, aldehydes, aromatic hydrocarbons, alcohols, and phenols). The relationship between the chemical composition and antimicrobial activity of P.guajava essential oil suggests that the attribution of its antimicrobial activity to a particular compound or a synergistic effects between its different constituents remains difficult. Conclusions. The present study demonstrated that Psidium guajava is a valuable source of active compounds with anti- oxidant and antimicrobial activities. This finding suggests the new use of the fruits and the leaves extracts of this plant in the treatment of bacterial and fungal infections, as well as for the extraction of new antioxidants. Therefore, it is necessary to be carried out in another study to identify the active(s) compound(s) in P.guajava essential oil with respect to their mechanisms and synergistic actions.

Opis:
The current study was intended to evaluate abortifacient and antioxidant activity of Avicennia marina leaves extracts. Abortifacient activity was evaluated in rats, compared with standard drug (Mifepristone) and antioxidant activity was evaluated by using three free radicals (Superoxide, Hydroxyl and DPPH) compared with Ascorbic acid. The extracts were showed pre implantation loss, post implantation loss of implantations and decreased the survival ration of foetuses. Among all extracts hydroalcoholic extract showed better activity. The selected plant extracts showed concentration dependent percentage inhibition of free radicals. Among three extracts hydroalcoholic extract showed better activity with IC50 values on superoxide, hydroxyl and DPPH radicals were 203μg, 237μg and 143μg. From the results obtained during the study it the hydroalcoholic extract was used for the isolation of pure compounds, and isolated the different compounds (β-sitosterol, Lupeol and Betulinic acid).

Opis:
This article offers publication of seventeen miniature vessels discovered in Hellenistic strata of Athribis (modern Tell Atrib) during excavations carried out by Polish-Egyptian Mission in the 1980s/1990s. The vessels, made of clay, faience and bronze, are mostly imports from various areas within the Mediterranean, including Sicily and Lycia, and more rarely – local imitations of imported forms. Two vessels carry stamps with Greek inscriptions, indicating that they were containers for lykion, a medicine extracted from the plant of the same name, highly esteemed in antiquity. The vessels may be connected with a healing activity practised within the Hellenistic bath complex.

Opis:
Epimedium pinnatum (Berberidaceae family) is used as an aphrodisiac in traditional Chinese medicine (TCM). The aim of this study was to evaluate the antimicrobial and antioxidant activity of E. pinnatum extracts (ethanol, methanol and aqueous extracts). Total phenolic (TPC) and flavonoid contents (TFC) of each extract were assessed by spectrophotometric methods. It was exhibited that methanol extract had better antimicrobial activity than those of ethanolic extract or aqueous extract. The TPC and TFC of E. pinnatum extracts was higher in methanol extract (149 and 36.6 mg/g) than that of ethanolic extract (137.2 and 19.5 mg/g) and aqueous extract (86.2 and 8.4 mg/g). The methanol extract had lower IC50 value (200 µg/ml) than ethanolic (250 µg/ml) and aqueous extract (400 µg/ml). There was a positive correlation between TPC, TFC in E. pinnatum extract and their antioxidant and antimicrobial activity.
W tradycyjnej medycynie chińskiej Epimedium pinnatum (rodzina Berberidaceae) używa się jako afrodyzjaku. Celem niniejszej pracy była ocena działania przeciwbakteryjnego i przeciwutleniającego wyciągów: etanolowego, metanolowego i wodnego z Epimedium pinnatum. Całkowita zawartość fenoli i całkowita zawartość flawonoidów w każdym z wyciągów została oznaczona metodami spektrofotometrycznymi. Wykazano, że wyciąg metanolowy miał lepsze działanie przeciwbakteryjne niż wyciąg etanolowy i wodny. Całkowita zawartość fenoli i całkowita zawartość flawonoidów była wyższa w wyciągu metanolowym (149 i 36,6 mg/g) niż etanolowym (137,2 i 19,5 mg/g) i wodnym (86,2 i 8,4 mg/g). Wyciąg metanolowy miał niższą wartość IC50 (200 µg/ml) niż wyciąg etanolowy (250 µg/ml) i wodny (400 µg/ml). Zauważono pozytywną korelację między całkowitym stężeniem fenoli i całkowitym stężeniem flawonoidów w wyciągach z E. pinnatum, a ich działaniem przeciwutleniającym i przeciwbakteryjnym.

Opis:
The higher fungi are a rich source of chemical compounds with multi-directional therapeutic and pro-health effects. This review summarizes the results of the most important chemical and biological studies of the fruiting bodies and the mycelial cultures of Laetiporus sulphureus. Numerous studies have demonstrated the antimicrobial, anticancer, cytotoxic, hypoglycemic anti-inflammatory and antioxidant activity of the extracts. Currently, only a few wood-decay fungi have practical use in medicine. Therefore it seems important to continue research on the effectiveness and safety of extracts and compounds of natural origin, including fungi, whose potential is not still used.
