Background and purpose: Chitin, which entails the most abundant biopolymer in nature after cellulose, having found numerous applications in food processing, cosmetics, agriculture, medical and environment. Natural sources of this polymer are component of exoskeletons of crustaceans and insects as well as cell walls from some bacteria and fungi. Chitosan is a partially deacetylated polymer of ...
Echinoderms are independent and quite special branch of world animals. Sea cucumbers are among the strangest members of echinoderm class regarding their structure and physiology. These fauna have been tested with regard to anti-bacterial, anti-fungal, anti-coagulants, anti-virus, cytotoxic, hemolytic and anti-HIV features. In this study, the antibacterial activity of Holothuria leucospilota...
The aim of this study was to evaluate the antibacterial activity of the water extracts of three species of Salvia (S. perspolitana, S. palaestina, S. bracteata) on Staphylococcus aureus, Escherichia coli and Pseudomonas aeroginosa. The antibacterial activity of water extracts of the studied species on the bacterial strains was examined using well diffusion method and minimum inhibitory concentr...
Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment of infections. Nanomedicines such as chitosan can carry multiple drugs and improve the therapeutic effects of antibiotics. Objectives: The study aimed to synthesis and characterization of ciprofloxacin loaded chitosan nanoparticle for eradication biofilm of P. aeroginosa. Methods: Cipro-CS microparticles...

Material and Methods: During two years,1897samples were...
In this study, extraction of the banana peels were done by two solvent kinds and water. Cytotoxic activityof extracts tested using assay MTT. Inhibition cells was 68.2% when peel wasextracted hexane, effect its cytotoxicity highest at 100 ?g/ml. On other hand,growth inhibition MCF-7 recorded concentration. While, ethanol extract thesecond stage according to which reached 54.1% followed watery s...
the essential oil of prangos ferulacea (apiaceae) fruits was obtained by hydrodistillation and analyzed by gas chromatography (gc) and gc-mass spectrometery (ms). among the 39 identified constituents accounting for 99.99% of the total oil, the major components were chrysanthenyl acetate (26.53%), limonene (19.59%), alpha pinene (19.50%), delta-3-carene (6.56%), mesitaldehyde (6.09), and germacr...
Pseudomonas aeroginosa Plays a Prominant role as an etiological agent involved in serious infection in burned Patients. This study analayzed Pseudomonas aeroginosa infections in the “Motahari Burn Center” during four months(from 22Dec.1998 to Apr.1999) in order to estimate their frequency, antibiotic susceptibility and serotyping. 184 positive culture with 205 bacterial strains were is...
