Staphylococcus aureus is bacteria identified in the root canal of infected teeth by 20%, resistant and isolated from secondary treatment. NaOCl 2.5%has toxic properties causes irritation when pushed into periapical tissue. Green okra fruit (GOF) extract has antibacterial metabolite compound i.e.flavonoids, alkaloids, saponins, tannins terpenoids. This research was carried out to determine inhib...

background one of the most common nasocomial bacteria is methicillin resistant staphylococcus aureus (mrsa). today, herbal extracts like zataria multiflora from the lamiaceae family are increasingly used. objectives in this study, the antibacterial effect of z. multiflora on 75 strains of was evaluated. materials and methods the strains of staphylococcus aureus were examined for isolation of st...

objective the extensive pollution of natural ecosystems has occurred by organophosphorus pesticides, being used for improvement of crop production in agriculture. biodegradation is interested in application of multifunctional bacteria containing genetical elements which specially degrade organophosphorus compounds. in this paper the detection of two bacteria species, pseudomonas and flavobacter...

Geum iranicum Khatamsaz, belonging to the Rosaceae family, is an endemic plant of Iran. The methanol extract of the roots of this plant showed significant activity against one of the clinical isolates of Helicobacter pylori which was resistant to metronidazole. The aim of this study was the isolation and evaluation of the major compounds of G. iranicum effective against H. pylori. The compounds...

The purpose of this study was to investigate the effects of tannins on starch digestion in tannin-containing sorghum extracts and wholegrain flours from 12 sorghum varieties. Extracts reduced amylase activity in a tannin concentration-dependent manner when the extract was mixed with the enzyme before substrate (amylopectin) addition, with higher molecular weight tannins showing greater reductio...

The major problem in drug manufacture nowadays is that many bacteria have evolved and became resistant to some particular drugs, these are referred as multidrug (MDR). reason for this being the overuse of antibiotics healthcare people recent past. These reduced efficiency already existing drugs also increased expenditure newer facilities. Therefore, novel effective new innovative therapies urge...

Tannins are naturally occurring protein-binding polyphenols that occur in many forage plants and which reduce nutritive value through inhibitory effects on ruminal and intestinal functions. Some animals have adapted to tannins through the synthesis of tannin-binding salivary proteins, the presence of tannin-resistant or tannin-degrading ruminal/intestinal microorganisms, or other potential adap...

Ippu Padang plant (Ammannia octandra L.f.) belongs to the family of Lythraceae, a hardy that can grow height 50 cm. According previous research, leaves contain glycosides, alkaloids, flavonoids and tannins. The presence alkaloid compounds, tannins is predicted have potential as an antifungal agent against fungi antibacterial agent. This research used experimental method. steps included collecti...

Plants are an abundant natural source of effective antibiotic compounds. Phytomedical investigations of certain plants haven't still been conducted. One of them is Najas minor (N. minor), an aquatic plant with confirmed allelopathy. Research conducted in this study showed the influence of water and ethyl acetate extracts of N. minor on microorganisms, in the view of chemical profiling of volati...

background mercury is one of the most toxic heavy metals. even a small amount of it is toxic for all living organisms. some of bacteria have developed special resistance mechanisms against mercury, in addition to resistant to different antibiotics. these bacteria usually acquire hg and antibiotic resistance genes via horizontal gene transfer in their habitat. objectives the aim of this study wa...
