background: deodorant products prevent the growth and activity of the degrading apocrine gland bacteria living in the armpit. common antibacterial agents in the market like triclosan and aluminum salts, in spite of their suitable antibacterial eff ects, increase the risk of alzheimer’s disease, breast and prostate cancers or induce contact dermatitis. th erefore, plant extracts possessing ant...

introduction: antibacterial activity is one of the desirable properties of an ideal sealer. this study aimed to compare the antimicrobial effect of three different sealers, i.e. resin (ah26), calcium hydroxide (apexit) and zinc oxide eugenol (zoe) based sealers.   materials and methods: direct contact test with agar diffusion was used in this in vitro study. the freshly mixed sealers were ah26,...

introduction: to assess the antibacterial effects of an iranian endemic essential oil, satureja khuzistanica jamzad (skj) when used as an intracanal antiseptic and interappointment medicament. materials and methods: antimicrobial activity and minimum inhibition concentrations (mics) of skj essential oil with and without calcium hydroxide (ch) against eleven aerobic, microaerophilic and anaerobi...

objectives this study explored the qualitative and quantitative antibacterial potential of c. intybus. further qualitative analysis of phytochemical content was performed. methods cichorium intybus seed extracts were prepared in aqueous, chloroform, ethanol, and hexane separately. results all the extracts of c. intybus seeds were screened for antibacterial activity and phytochemical content. ci...

rheum ribes is among the polygonaceae family which is endemic in iran and a few neighboring countries. in this investigation, antibacterial effects of root, stalk and leaves extracts of rheum ribes on a few common clinical isolates of gram negative pathogens were studied, using the cup plate and paper disc methods. gram negative microorganisms studied were escherichia coli, klebsiella pneumonia...

background and objectives: antibiotic therapy is the main choice in treatment of escherichia coli induced infections. using herbal medication is an alternative choice in treatment of diseases. the aim of this study was to determine the antibacterial activity of two traditionally used herbs in iranian medicine, anacyclus pyrethrum and pistacia lentiscus l., on escherichia coli. materials and met...

emergence of resistance among pathogenic bacteria against available antibiotics is posing a great challenge to the current world. thus, there is a great need to discover novel antibiotics. traditional plants have been proved to be novel source in the search of antimicrobial compounds. the current study pertained to the susceptibilities of some clinically significant bacterial species to various...

background: according to the recent studies, the antibacterial activities of silver nanoparticles (ag-nps) were studied on gram-positive staphylococcus aureus and gram-negative escherichia coli. in this study antibacterial effect of silver nanoparticles that used for coating textiles, on e.coli and s.aureus was investigated. methods: silver nanoparticles were coated on textile fabric by corona ...

background and objectives:plant essential oils are sometimes considered for use as antimicrobial agents in foods and medicines and they could be combined with other antimicrobial agents to strengthen the effect and/or reduce the required dose. this study was conducted to determine the chemical composition of the ocimum basilicum, salvia officinalis and trachyspermum ammi essential oils and eval...

a simple, inexpensive and one-step synthesis route of ag-tio2 nanoparticles by arc discharge method isreported. the resulting nanoparticles were characterized using x-ray diffraction and scanning electronmicroscopy. x-ray diffraction patterns demonstrate dominance of rutile to anatase phase in tio2 andformation of silver metal on tio2 after arc discharge process. scanning electron microscopy im...
