In some situations, endodontic infections do not respond to therapeutic protocol. In these cases, it is suggested the administration of an alternative intracanal medication that presents a wide spectrum of action and has an in-depth effect on the root canal system. The purpose of this study was to assess the antimicrobial action of ciprofloxacin, metronidazole and polyethylene glycol and natros...

OBJECTIVES Epidemiological studies of statins have suggested a link between statin therapy and a decreased risk of sepsis. It has been proposed that the mechanism underlying this apparent protective effect of statins relates to their known immunomodulatory and anti-inflammatory effects. The aim of this study was to explore the antimicrobial effect of statins. METHODS Simvastatin (Merck) and f...

regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. the current study was performed to determine antimicrobial potenti...

INTRODUCTION The aim of the present study was to determine the antimicrobial effect of various gel formulations on plaque formation; different tooth gels were compared to a toothpaste containing comparable antimicrobial ingredients with regard to its microbiocidal activity. The study was conducted under the assumption, that a chief requirement for the prevention of plaque formation is the combi...

Antibiotic use has led to increased resistance to certain group markers: penicillin, erythromycin and ciprofloxacin for beta-lactams, macrolides and quinolones, respectively. The influence of resistance to markers in decreasing susceptibility to the drugs included (on the basis of chemical structure) in the corresponding antibiotic group can be defined as 'resistance class effect'. In the case ...

The objective of the study was to investigate antimicrobial activity of native and reduced forms of duck lysozyme (dLz) against Salmonella enteritidis. Moreover, antimicrobial activity of dLz was compared with chicken lysozyme (cLz). The purified dLz was reduced with dithiothreitol. Free SH groups of reduced dLz were trapped with iodoacetamide. Lytic activity against Micrococcus luteus of reduc...

Hyssopus of­ficinalis L. is one of the most important medicinal plants. Medicinal herbs are contaminated by microorganisms. Conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

oil from the eucalyptus tree ( eucalyptus camaldulensis l.) is used today in many over the counter cough and cold products, to relieve congestion. eucalyptus oil is also used in creams and ointments to relieve muscle and joint pain, and in some mouthwashes. in this study eucalyptus camaldulensis leaves extracted with water and ethanol 96°and the antimicrobial effects of extracts were evaluated ...
