objective(s) aim of the present study was to screen the antibacterial activities of some medicinal plants extracts traditionally used in azarbaijan area (iran). materials and methods thirty-six extracts obtained from differ...
conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...
Background and Objective: Since the preparation of antibacterial materials in dentistry is very noticeable, therefore, we tried to evaluate this effect on Streptococcus mutans by addition of silica nanoparticles to LCGI (light curing glass ionomer). Materials and Methods: In this in vitro study, we had five LCGI experimental groups that contained 0, 0.2, 0.5, 1, and 2% (w/w) of silica nanopa...
background and objectives : resistance among bacterial isolates is the leading cause of increased mortality and morbidity worldwide. carbapenems once thought to be effective are becoming ineffective mostly due to the emergence of carbapenemase. this study was designed to determine in vitro efficacy of modified hodge test for detection of carbapenemase production in gram negative rods. material ...
This study was conducted for determination of antibacterial effect of Echinometra mathaei extraction on human disease bacteria. Samples were collected in Abu Mosa Island. Extraction operation was done by shell, spines, gonad and aristotle's lantern. Ethyl acetate, n-hexane and methanol were used for extraction operation respectively. Extraction effect of these organs was investigated on Vibrio ...
background: recently the role of platelets in the tissue regeneration, wound healing and prevention and control of infections has been reported. we aimed to assess the antimicrobial effect of human platelet concentrate against six bacteria, commonly found in wound and hospital-acquired infections. methods: in vitro susceptibility to samples of 10 random human platelet concentrates was determine...
objective: sea cucumber is a traditional food and medical item and has been reported to exhibit antioxidant, antifungal, anti tumoral and antibacterial bioactivity. the objective of this study is to describe the antibacterial activity of 4 extracts of holoturia. sp (sea cucumber), collected from hengam island of persian gulf. materials and methods: methanol, hexane, aqueous and chloroform extr...
BACKGROUND Direct pulp capping involves the application of a dental material to seal communications between the exposed pulp and the oral cavity (mechanical and carious pulp exposures) in an attempt to act as a barrier, protect the dental pulp complex and preserve its vitality. The aim of this study was to evaluate and compare, by the agar disc diffusion test, the antimicrobial activity of six ...
objective: bioactive glass 45s5 is a surface reactive glass-ceramic biomaterial, developed in 1969. bag 45s5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. the aim of this study was to evaluate the antibacterial activity and determine mic and mbc values of nano-bag45s5 on streptococcus muta...
background and objective: reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (cons). the objective of the present study was to compare and evaluate the performance of disc diffusion and e test (epsilometer test) methods for antimicrobial testing of coagulase negative staph...
