methanolic and aqueous extracts of dendrophthoe falcata linn. leaves which belongs to the loranthaceae family, were evaluated through dpph (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. methanolic and aqueous extracts of dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...

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,...

A series of 5-thiocarbamate oxazolidinones was prepared and tested for in vitro and in vivo antibacterial activities. The results of in vitro antibacterial activity indicated that the 5-thiocarbamate group was a suitable substituent for the activity by the 5-moderate hydrophilicity. The compounds within a favorable logP value range were found to have potent in vitro antibacterial activity again...

OBJECTIVE To investigate the in vitro effects of the antibacterial drugs, meropenem trihydrate, piperacillin sodium, and cefoperazone sodium, on the activity of human serum paraoxonase (hPON1). METHODS hPON1 was purified from human serum using simple chromatographic methods, including DEAE-Sephadex anion exchange and Sephadex G-200 gel filtration chromatography. RESULTS The three antibacter...

Objective: Intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. The present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. Methods: In the present st...

A microbroth dilution method was used to measure the MICs of cefpiramide (SM 1652), cefotaxime, moxalactam, ceftazidime, cefoperazone, ceftriaxone, piperacillin, and mezlocillin against 921 isolates of gram-negative (701) and gram-positive (220) bacteria. The activity of cefpiramide was equivalent to those of piperacillin and mezlocillin against members of the family Enterobacteriaceae and gram...

Mouthwashes are used as an adjunct to tooth brushing for improving breath and preventing oral diseases. The aim of this study was to compare the in vitro Maximum Inhibitory Dilution (MID) of 3 mouthwashes with different active ingredients against mutans streptococci (MS). The products analyzed were Periogard®, Cepacol® and Plax® Fresh Mint. Their antibacterial activity was assessed in duplicate...

Background & Aim: The major aim of this study was to determine the antibacterial activity of the essential oils from five medicinal plants. Experimental: The hydro-distillation essential oils from five plant species, including Satureja bachtiarica, Zataria multiflora, Thymus daenensis, Thymus carmanicus, and Ziziphora tenuior (Lamiaceae) which are e...

Cinoxacin is a new synthetic compound similar chemically and in antimicrobial activity to oxolonic acid and nalidixic acid. It is most effective against Escherichia coli and Proteus mirabilis, but at concentrations expected in the urine it is inhibitory for all species of Enterobacteriaceae. Relative to nalidixic acid, cinoxacin has slightly greater inhibitory and bactericidal activity, less in...
