The antimicrobial activity of plant hidroethanolic extracts on bacteria
Gram positive, Gram negative, yeasts, Mycobacterium tuberculosis H37
and Mycobacterium bovis was evaluated by using the technique of Agar
diffusion and microdilution in broth. Among the extracts evaluated by Agar diffusion,
the extract of Bidens pilosa leaf presented the most expressive
average of haloes of growth inhibition to the microorganisms, followed by the extract
of B. pilosa flower, of Eugenia pyriformis'' leaf
and seed, of Plinia cauliflora leaf which statistically presented
the same average of haloes inhibitory formation on bacteria Gram positive, Gram
negative and yeasts. The extracts of Heliconia rostrata did not
present activity. Mycobacterium tuberculosis H37 and
Mycobacterium bovis (BCG) appeared resistant to all the extracts.
The susceptibility profile of Candida albicans and
Saccharomyces cerevisiae fungi were compared to one another and
to the Gram positive Bacillus subtilis, Enterococcus
faecalis and the Gram negative Salmonella typhimurium
bacteria (p > 0.05). The evaluation of cytotoxicity was carried
out on C6-36 larvae cells of the Aedes albopictus mosquito. The
extracts of stem and flower of Heliconia rostrata, leaf and stem of
Plinia cauliflora, seed of Anonna crassiflora
and stem, flower and root of B. pilosa did not present toxicity in
the analyzed concentrations. The highest rates of selectivity appeared in the
extracts of stem of A. crassiflora and flower of B.
pilosa to Staphylococcus aureus, presenting potential
for future studies about a new drug development. 相似文献

Recently, the Surgeon General put out a Call to Action “To Promote Walking and Walkable Communities.” Walking is a powerful health promotion activity that nurse practitioners (NPs) can quickly prescribe as part of a management plan for the vast majority of their patients. NPs are key health care professionals in the promotion of walking and other physical activity for their patients across the life span. NPs should be familiar with physical activity recommendations for all of their patients, including patients with disabilities. NPs need to be able to assess physical activity as well as prescribe individualized physical activity plans. 相似文献

In the present study, we have evaluated the antifungal activity of the seed, root and leaf of Paeonia emodi (commonly known as Himalayan peony) in four common solvents (acetone, chloroform, methanol and water) against six fungal strains. The methanolic seed extract (MSE) showed promising antifungal activity against Candida albicans (6.25 mg/mL), Candida glabrata (3.12 mg/mL) and Candida parapsilosis (12.50 mg/mL) among all the fungal strains tested. Combination of the MSE with the well-known commercial antifungal drugs amphotericin B (Amp B), nystatin (NYS) and fluconazole (FLC) resulted in the killing of C. glabrata at non-inhibitory concentrations, i.e., 0.35 μg/mL for Amp B, 0.55 μg/mL for NYS and 1.19 μg/mL for FLC. Notably, MSE caused cell wall damage of C. glabrata cells, as confirmed by confocal microscopy, flowcytometry and scanning electron microscopy (SEM). The MSE was fractionated by thin layer chromatography (TLC). TLC-bioautography was used to determine the active compounds present in the MSE. Column chromatography was used to separate the potential active compounds from the MSE. Furthermore, gas chromatography-mass spectrometry (GC-MS) andfourier-transform infrared spectroscopy (FTIR) were used to identify the phytocomponents of the MSE. These experiments revealed 13-docosenamide/9-octadecenamide/trans-13-docosenamide (89.70%) as being the predominant compound using a chloroform/methanol solvent system for the separation. Interestingly, the MSE also exhibited less significant cytotoxicity at the minimum inhibitory concentration (MIC) against mammalian cells (HeLa and HEK293). This study suggests that the MSE of P. emodi can be used for the treatment of C. glabrata infection. 相似文献

This study assessed whether exercising whilst viewing natural or built scenes affected self-esteem (SE) and mood in adolescents. Twenty-five adolescents participated in three exercise tests on consecutive days. A graded exercise test established the work rate equivalent to 50% heart rate reserve for use in subsequent constant load tests (CLTs). Participants undertook two 15-min CLTs in random order viewing scenes of either natural or built environments. Participants completed Rosenberg’s SE scale and the adolescent profile of mood states questionnaire pre- and post-exercise. There was a significant main effect for SE (F(1) = 6.10; P < 0.05) and mood (F(6) = 5.29; P < 0.001) due to exercise, but no effect of viewing different environmental scenes (P > 0.05). Short bouts of moderate physical activity can have a positive impact on SE and mood in adolescents. Future research should incorporate field studies to examine the psychological effects of contact with real environments. 相似文献
