the toxicity of 7 herbicides to the three cyanobacteria was tested in this work. the results indicated that: (1) there was a highly significant relationship between dried weight or chlorophyll-a and od680nm for tested cyanobacteria; (2) the toxicity of the tested herbicides with the order from high to low was: photosynthesis-inhibiting > accase inhibitor > protox inhibiting herbicides; (3) the ...

determination of the frequency of bacteria isolated from blood culture and the pattern of their antibiotic sensitivity is epidemiologically of great importance and can help choosing primary antimicrobial treatment. the aim of the current study was to determine the most common bacterial factors of blood infection and their antibiotic sensitivity in a one year period from october 2010 till the en...

backgrond burn wound infections carry considerable mortality and morbidity amongst burn injury victims who have been successfully rescued through the initial resuscitation. this study assessed the prevalent microrganisms causing burn wound infections among hospitalized patients their susceptibility pattern to commonly used antibiotics and the frequency of infections with respect to the duration...

objective: as the aqueous extract of capparis spinosa (cs) possess antidiabetic effect, he present study aims to reveal the possible  mechanism of action of cs in diabetic mice.materials and methods: both single and repeated oral administrations of aqueous extract of cs were performed in multi-low dose streptozotocin-induced (mlds) diabetic mice. euglycemic hyperinsulinemic clamp was used in as...

objectives : the aim of this in-vitro experimental study was to assess the effect of application of a desensitizing varnish on the enamel and dentin marginal seal. materials and methods: seventy-two freshly extracted, intact human premolar teeth were divided into four groups (n=18). class v cavities (3mm in length, 2mm in width and 2mm in depth) were prepared on the buccal surface of each tooth...

sepsis is a significant cause of morbidity and mortality in neonates. the most common pathogens of bacterial sepsis and antibiotic sensitivity patterns vary in different parts of the world. the aim of this study was to determine the most common pathogens and outcome of neonatal sepsis and also antibiotic sensitivity patterns of klebsiella species. a retrospective descriptive study was carried o...

conclusions: considering the low rate of ceftriaxone resistance amongst isolated pneumcocci.in this study, only ceftriaxone treatment of adult patients with invasive pneumococcal infections (other than cns infections) is sufficient; but pediatric patients and patients with cns infections should be treated with ceftriaxone and vancomycin. apparently, diminution of vancomycin use can be resulted ...

background: asthma is a multifactorial disease and its severity varies with the inflammatory grade. there are conflicting reports about the roles of trace elements in asthma. this study examined the effects of zinc (zn), copper (cu), and selenium (se) concentrations in sera of patients with allergic asthma attending ghaem hospital, mashhad, iran. methods: forty-nine patients, aged 10 to 50 year...
