Propolis is a bee product, composed mainly of plant resins and beeswax, therefore its chemical composition varies due to the geographic and plant origins of these resins, as well as the species of bee. Brazil is an important supplier of propolis on the world market and, although green colored propolis from the southeast is the most known and studied, several other types of propolis from Apis me...
Propolis possesses various biological activities such as antibacterial, antifungal, anti-inflammatory, anesthetic and antioxidant properties. A topically applied product based on Brazilian green propolis was developed for the treatment of burns. For such substance to be used more safely in future clinical applications, the present study evaluated the mutagenic potential of topical formulations ...
The purpose of this study was to evaluate the antimicrobial activity of two experimental pastes containing propolis extract associated with calcium hydroxide against polymicrobial cultures collected from 16 necrotic and fistulae root canals in primary molars of 4-8-year-old children of both sexes. The agar-well diffusion technique was used to determine the antimicrobial activity of the followin...
The present experiment was conducted to study the effect of ethanolic extract of Egyptian propolis given alone or in combination with inactivated Pasteurella multocida vaccine on rabbits challenged with a virulent strain of Pasteurella multocida. Fifty-six New-Zealand rabbits, 6-8 weeks old and non-vaccinated against pasteurellosis, were randomly divided into eight equal groups. The first group...
Background & Aim: Propolis is a natural material that is produced by the honey bee and has a variety of beneficial properties, including an anti- inflammatory effect. In this study, the effect of oral administration of ethanolic extract of propolis was investigated on formalin-induced inflammatory pain in male mice. Methods: This experimental study was undergone in 2016 in the Qazvin Universit...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
Propolis extracts have gained the attention of consumers and researchers due to their unique chemical compositions and functional properties such as its anti-inflammatory activity. Recently, it was described a complex that is also important in inflammatory processes, named inflammasome. The inflammasomes are a large molecular platform formed in the cell cytosol in response to stress signals, to...
The present study is aimed to evaluate the chemical characterization and antimutagenic potential of propolis extracted in three different solvents (ethanol, polyethylene glycol water). properties extracts were identified using HPLC-DAD LC?MS/MS extract found be richer than ethanolic water considering composition. In addition, activities determined Ames assay. concentrations 3, 1.5 0.75 mg plate...
Th e infl uence of the diff erent extracts of propolis and chlorhexidine on mutans streptococci and the development of dental caries in rats was examined in this study. Specifi cally, the antimicrobial eff ects of propolis extracts (including ethanol, methanol, chloroform, hexane, propylene glycol, and ethyl acetate) on Streptococcus mutans UA159 and Streptococcus sobrinus 6715 were studied. Mi...
Different products from a unique propolis extract obtained by using various solvents such as hydroalcoholic, glycolic (98% propylene glycol), and glyceric solutions, and oil, as well as in powder form, named ESIT12, were prepared. The molecular composition of the different preparations was evaluated and their antioxidant activity determined. All the preparations showed a quite similar polypheno...
