Opis:: The aim of the present study was to determine the level of ginsenosides in extracts from hairy root A, B, G clones of Panax quinquefolium and their action with antibiotics against clinical bacterial isolates. The content of ginsenosides (the key biologically active compounds) were determined in tested extracts using HPLC. The activity of extracts with antibiotics was established by micro-dilution broth method. Total triterpene saponin content was 14.68, 14.32 and 10.07 mgg-1 d.w. for root culture clones B, A and G, respectively. Our research indicates that the addition of extracts mainly from B and G clone hairy root cultures to antibiotics allow to reduce the ampicillin and tetracycline effective concentration respectively against Enterococcus faecalis and both Escherichia coli and Acintobacter baumannii.

Tematy:: Escherichia coli, clove oil, urinary tract infections
Opis:: Escherichia coli is a Gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium, which is a primary cause of urinary tract infections. Resistance to antibiotics has become a particular problem in recent decades. Consequently, there is an unmet need for new therapeutic options. It has been observed that essential oils have bactericidal effects. The antimicrobial susceptibility testing for Escherichia coli isolates obtained from urine of patients with urinary tract infections was determined via disk diffusion method according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST, 2015). Essential oil from clove – Syzygium aromaticum (L.) Merill et L.M. (Myrtaceae) was analyzed by GC-FID-MS. Minimal Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) were detected by using the micro-dilution broth method. Escherichia coli clinical isolates are characterized by high resistance to ampicillin, amoxicillin with clavulanic acid, norfloxacin, trimethoprim/sulfamethoxazole, tetracycline, tobramycin and ticarcillin. Clove oil possesses strong inhibiting and killing properties against E. coli isolates, among them the ones resistant to recommended antibiotics. The results of this study highlight the need for testing the efficacy of new agents to inactivate bacteria in clinical settings.

Opis:: BackgroundWhen assessing physical activity (PA), particular attention should be paid to medical university students who are taught to be health care professionals (HCPs) responsible for maintaining health in humans. However, different studies have shown that HCPs exhibit the same unhealthy behaviors as the general population. This study analyzed PA among medical university students of different faculties and their adherence to current PA recommendations.Material and MethodsData from 216 medical university students of physiotherapy, dietetics and pharmacy, including males (N = 44) and females (N = 172), the mean age of 22.3±1.8 years, were collected. The International Physical Activity Questionnaire in its long form (IPAQ-LF) was used to assess and classify PA behaviors. The results were analyzed in accordance with World Health Organization recommendations regarding PA.ResultsOver 60% of all the students were classified as active during all-day activity. However, while analyzing PA in different domains, the same shares of all the students were still insufficiently active during leisure time, and so they did not meet the recommendation of >75 min/week of vigorous PA, >150 min/week of moderate PA or an equivalent combination. All the students self-reported PA mainly in the work and transport domains. Generally, physiotherapy students were the most active and performed PA with higher intensity.ConclusionsThis study revealed a low level of leisure time PA among the students, and no habit of regular PA. Some changes in medical education should be suggested to include physical education as a long-term subject in medical school curricula. Future research is needed to investigate the exercise barriers that students perceive, which can guide future interventions aimed at improving their PA, and thereby impact on the quality of health care which they will provide.

Tematy:: Panax quinquefolium L. suspension culture, ginsenosides, bioreactor
Opis:: Plant suspension cultures are described as a source for the acquisition of medicinal secondary metabolites which in the future may become an alternative to traditional raw materials. This study demonstrates that the cell cultures of one of the ginseng species – Panax quinquefolium L. synthesize ginsenosides, which are triterpene saponins having a multidirectional pharmacological effects. Tested suspension cultures were run on a small scale in the shake flasksand in scale up of the process in a 10-liter stirred tank. In the shake flasks,the highest biomass yield (2.28 gl-1 for dry and 33.99 gl-1 for fresh weight) was reached on day 30 of culture, and the highest content of saponins (2.66 mg g -1 dw) was determined on day 28 of culture. In the bioreactor, nearly 2.67 and 3-fold increase of respectively dry and fresh biomass was recorded in relation to the inoculum. Large-scale cultures synthesized protopanaxatriol derivatives such as Rg1 and Re ginsenosides, however, no saponins belonging to the protopanaxadiol derivatives were reported.

Tematy:: Panax quinquefolium suspension culture, methyl jasmonate, ginsenosides, elicitation
Opis:: Panax quinquefolium L., belonging to the Araliaceae family, along with P. ginseng is one of the well-known species of ginseng. Multidirectional pharmacological action of this plant is attributed to triterpene saponins called ginsenosides. Pharmacopoeial raw material are roots obtained from the field crops which are time-consuming and require expensive agrotechnical procedures. Therefore, the new sources of ginseng biomass are sought such as in vitro suspension cultures. P. quinquefolium L. cell cultures, treated with the elicitation of methyl jasmonate (MJ) in concentration 50 and 250 μmol L-1, synthesize more ginsenosides than control cultures. The highest increase (2.2-fold) of all examined compounds was noted using 250 μmol L-1 MJ. In this condition, the predominantly quantitative metabolite was Rb1 ginsenoside belonging to protopanaxadiol derivatives.
