Strong antiseptic activity of essential oils has been known for a long time. The antibacterial activity of oils was tested against clinical bacterial strains of Staphylococcus, Enterococcus, Escherichia and Pseudomonas genera. The agar diffusion method was used for microbial growth inhibition at various concentrations of the oils from T. vulgaris and L. angustifolia. Susceptibility testing to antibiotics and chemotherapeutics was carried out using disc-diffusion method. 120 strains of bacteria isolated from patients with infections of oral cavity, respiratory, genitourinary tracts and from hospital environment were investigated. The results of experiments showed that the oil from T. vulgaris exhibited extremely strong activity against all of the clinical strains. Thyme oil demonstrated a good efficacy against antibiotics resistant strains of the tested bacteria. Lavender oil has been less activity against clinical strains of Staphylococcus, Enterococcus and Escherichia genus. The worst results have been observed against all strains of Pseudomonas aeruginosa.
Decreased plasma total antioxidant activity, NO, and VEGF levels in patients with metabolic syndrome reflect significant endothelial dysfunction. This suggests that oxidation-reduction balance disorders might play an important role in this process.
Metabolic syndrome (MS) is associated with occurrence of the many cardiovascular risk factors such as atherogenic dyslipidemia, visceral fat distribution, arterial hypertension and pro-thrombotic and pro-inflammatory status. In our study the effect of disorders that appear in MS on red-ox balance and erythrocyte cell membrane properties were estimated. The study comprised 50 patients with diagnosed MS and in 25 healthy subjects. Content of thiobarbituric acid reactive substances (TBARS) and catalase, superoxide dismutase and glutathione peroxidase activity were estimated in red blood cells. Moreover, conformation status of membrane proteins, membrane fluidity and osmotic fragility were evaluated. MS was found to manifest: (1) the increase of the concentration of TBARS in erythrocytes with no statistically significant differences in antioxidant enzymes activity, (2) disorders in the structure of erythrocyte cytoskeleton proteins, (3) the increase in membrane lipids fluidity at the depth of 5th and 12th carbon atom of fatty acid hydrocarbon chain and significantly decreased fluidity at the depth of 16th carbon atom, (4) increased erythrocyte osmotic fragility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
