background: iran is a land of great heritage of ancient medical scholars. herbal medicines, as a basement of treatment of diseases have been clearly described in the medical texts of these scholars including rhazes, avicenna, and others. numerous plants are introduced in these texts to treat those diseases likely to be infective ones. few attempts have been made to evaluate ethnopharmacological...

The major ingredient of Cinnamomum, which is cinnamic aldehyde, has a variety of uses, such as aromatic compound, beverage, chewing gum, toothpaste, and incense as a component of cosmetics, and halitosis remover. Cinnamic aldehyde is also known to have a remedial effect. In this study, Cinnamomum is used to look for antibacterial activity on oral bacteria. A disk diffusion method is used as the...

the aim of this study was to assess the antibacterial activities of some medicinal plants extracts traditionally used in iran. hydroalcoholic extracts obtained from different parts of five plants including rosmarinus officinalis l. (rosemary), syzygium aromaticum l. (clove)., arctium lappa l. (burdock) , coriandrum sativum, myrtus communis with traditional medicinal use were examined for their ...

OBJECTIVES On December 2013, the US FDA proposed a rule stating that manufacturers must provide data to demonstrate that antibacterial soap is more effective than plain soap or water. The objective of the present study was to examine the in vitro and in vivo bactericidal effect of triclosan (the most widely used antiseptic agent in soap) in soap. METHODS Twenty bacterial strains (proposed by ...

Musca domestica L. (Diptera: Muscidae), the housefly, exhibits unique immune defenses and can produce antibacterial substances upon stimulation with bacteria. On the basis of the cDNA library constructed using the suppression subtractive hybridization method, a 1188-bp antibacterial substance gene, which we named AS566, was amplified by rapid amplification of cDNA ends from M. domestica larva s...

BACKGROUND Different researches on therapeutic effects of honey have been conducted in different regions; however the study on the potential antibacterial activity of Malaysian honey is still limited. In this study, antibacterial activities of different monofloral honey samples were tested against several common human pathogenic bacteria. MATERIALS AND METHODS The well-diffusion method, minim...

Photocatalysts produce free radicals upon receiving light energy; thus, they possess antibacterial properties. Silver (Ag) is an antibacterial material that disrupts bacterial physiology. Our previous study reported that the high antibacterial property of silver nanoparticles on the surfaces of visible light-responsive nitrogen-doped TiO2 photocatalysts [TiO2(N)] could be further enhanced by vi...

Amniotic membrane (AM), the innermost layer of the fetal membranes, has been widely employed in the surgical reconstruction and tissue engineering. Expression of the antimicrobial peptides such as defensins, elafin and SLPI which are essential elements of the innate immune system results in antibacterial properties of the AM. Preservation is necessary to reach a ready-to-use source of the AM. H...

In the present study the adaptogenic activities of the saponin fractions of the leaves and roots of Polyscias fruticosa (L) Harms (Araliaceae) were studied in comparision wit white panax ginseng root saponins. The antibacterial activity of the polyacetylenic compound in leaves were also studied. The adaptogenic activity studies showed that polyscias fruticosa leaf and root saponins have effecti...

To make use of nano-sized particles for biomedical applications such nanomedicines for different diseases, it is important to study how nanoparticles behave when they interact with microorganisms. In the present study, we investigated the antibacterial performance of chromium oxide nanoparticles (Cr3O4 NPs) against two gram negative bacterial strains, Escherichia coli, and Pseudomonas aeruginos...
