background & aim:vaginal disease has always been a great concern of women. medicinal plants as natural resources with fewer side effects can effectively treat these infections given the diversity of these infections, resistance to antibiotics and side effects of existing drugs. the present study aimed to compare antimicrobial effects of methanol extract of francoeuria undulata on growth of seve...

background : this study investigated the in vitro and in vivo antibacterial effects of three mouthwashes on su-pragingival plaque microbiota. the three mouthwashes under study were 0.2% chlorhexidine (chx), listerine®, and persica (pm). water was used as negative control. methods : supragingival plaque samples were collected from 32 patients with gingivitis in the dental school of shahid behesh...

the plants of the genus salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. eleven salvia species including s. aegyptiaca, s. aethiopis, s. atropatana, s. eremophila, s. hypoleuca, s. limbata, s. nemorosa, s. santolinifolia, s. sclarea, s. syriaca, and s. xanthocheila ...

background & aim: the purpose of present study was to examine and validate the folk's claim of inhalation of monechma ciliatum seeds powder by traditional african natives for cold and allergic conditions, so as to formulate a useful therapeutic agent to respiratory tract infections. experimental: different extracts were bio-assayed in vitro for their bioactivity to inhibit the growth of pat...

the external and interlamellar spaces of montmorilonite (mmt) were used as solid support for synthesis of cuo nanoparticles (nps) at room temperature by the chemical reduction method. in this project, copper nitrate plus water (cu(no3)2. xh2o) and sodium hydroxide (naoh) were used as copper precursor and reducing agent respectively. then, mmt/cu2+ nanocomposites were stabilized with different r...

conclusions probable mechanism of suppression of energy generation is suppression of the rise in glucose. results listeria monocytogenes was controlled using 2 mm of osthole. treatment of l. monocytogenes by 2 mm osthole had no effect on the atp level. objectives osthole has antibacterial properties, but its mechanisms of action is still unknown. materials and methods two millimoles of osthole ...

quinolones are a very important family of antibacterial agents that are widely prescribed for the treatment of infections in humans. since their discovery in the early 1960s, the quinolone group of antibacterials has generated considerable clinical and scientific interest. two major groups of compounds have been developed from the basic molecule: quinolones and naphthyridones. the 4-pyridone-3-...

during the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. in this study, the antibacterial activity of methanolic extract of t. pubescens (rich i...

background and objective: uttarakhand region is less explored, but possess a great biodiversity. this diversity can be explored for isolation and characterization of new actinomycetes strains for seeking antimicrobial molecules. it can therefore be predicted that novel bioactive metabolite producing actinomycetes can be discovered to combat multidrug resistant bacterial pathogens. materials and...

background :   chitosan is unbranched polysaccharide composed of d-glucosamine and n-acetyl-d-glucosamine. chitosan, derived from shrimp shell, has broad antimicrobial properties against gram-negative, gram-positive bacteria and fungi.   methods :  chitosan was extracted from shrimp shell and studied for cell entrapment and anti-bacterial properties. the hydrogel chitosan was used as the beads ...
