purpose: in this study the inhibitory effect of eucalyptus extracts as a natural and herbal antibacterial substance was evaluated against pseudomonas aeruginosa strains (8821m and atcc27853). material and methods: the mic (minimal inhibitory concentration) of alcoholic and aquatic extracts of eucalyptus was determined using the tube and agar dilution methods. the growth rate of pseudomonas aer...

background and objective: although there are reports in the literature on the antimicrobial effects of green tea, the effect of black tea, the most common beverage in iran, on growth of bacteria, such as streptococcus pyogenes, has not been studied extensively. this study was undertaken to determine the inhibitory effect of black tea on the growth of streptococcus pyogenes in vitro and compare ...

background: in recent years, drug resistance to human pathogenic fungi has been increased. medicinal plants are one way to overcome antibiotic resistance. the aim of this study was to evaluate the antifungal and inhibitory activity of five medicinal plants on the growth of candida albicans. methods: this study was done in the microbiology lab of shahid bahonar university of kerman, iran in 2015...

a kinetic spectrophotometric method for rapid measurement of thiocyanate in serum, urine and sewage water with no need for removed of interfering substances in described. the method is based on the inhibitory effect of thiocyanate on the oxidation of pyrogallol red by bromated and nitrite which is monitored at 467 nm. the variables affecting the rate of the reaction were investigated and the op...

backgrounds and objectives: photocatalyst titanium dioxide nanoparticles can oxidize organic and inorganic compounds of microorganisms in aqueous solutions after exposure to uv light. in the present study, the inhibitory effect of titanium dioxide and its photocatalyst type on aspergillus flavus , escherichia coli and staphylococcus aureus is investigated.   materials and methods: toxicogenic s...

aquatic animals are important resources for extraction of valuable compounds such as enzymes. in this study, lipase was extracted from the intestine of rainbow trout. samples were defatted with acetone several times; ammonium sulphate (60%) was used for precipitation followed by ultrafiltration for concentrating the samples. the final purification of the enzyme was performed by passing of the s...

cytokines influence cell cycle events, which in some but not all instances can be associated with melanoma progression. analysis of the g0/g 1 and s phase fractions of the cell cycle was used to assay the proliferative or inhibitory activity of cytokines against ten human melanoma cell lines, including pairs of cell lines derived from primary and metastatic tissue of individual patients. cytoki...

abstract introduction: there are many studies about the inhibitory effect of the esophageal distention (ed) on gastric motility. recently, it has been shown that ed decreases the gastric secretions. it is well established that the inhibitory effect of ed is mediated by activation of vago-vagal inhibitory reflex. however, there is not any investigation about the effect of the reflex on the gastr...
