Male Wistar rats were exposed to 0.2 ppm ozone for up to 14 days, during which alveolar macrophages were collected by pulmonary lavage to assess the effect of ozone on their microbial killing and superoxide-producing activities. For rapid assessment of microbial killing activity, we measured the release of H-radioactivity into the supernatant by deoxycholate-lysis of the macrophages that had ph...

Objective: To explore the phytochemical and antimicrobial activities as well as the insecticidal properties of the different sections of Ricinus communis (castor) plant in Mauritius. Methods: Qualitative and quantitative methods were used for the determination of phytochemicals in the crude leaves, pericarp, seeds, bark and root extracts obtained by using polar and non-polar solvents. The disc ...

Objective: The objective of this study was to investigate the antibacterial activities of combination of MgO and ZnO nanoparticles in the presence of heat against Escherichia coli and Staphylococcus aureus. Materials and Methods:Bacteria were grown on either agar or broth media followed by the addition of ZnO and MgO nanoparticles. Then the combined effect of ZnO and MgO nanoparticles was inves...

The rapid increase in drug resistance among bacteria is a public health challenge in the 21 century. To combat drug resistance, searching for new broad-spectrum antibiotics is urgent and marine microbial flora may be a potential source. The present study was designed to isolate marine actinomycetes strains (AIAH-01 to AIAH-29) from the soil sediments of different locations of the sundarbans man...

abstract background and purpose: in traditional medicine, herbal products still remain the principal source of pharmaceutical agents. the present study aimed to investigate the antifungal effects of echinophora platyloba and rosmarinus officinalis extracts on c. albicans species. materials and methods: the aqueous and ethanolic leaf extracts of e. platyloba and r. officinalis, collected from th...

BACKGROUND Cassia fistula, is a flowering plant and a member of Fabaceae family. Its leaves are compound of 4 - 8 pairs of opposite leaflets. There are many Cassia species around the world which are used in herbal medicine. OBJECTIVES This study was designed to examine in vitro anti-bacterial activity of methanolic and ethanolic extracts of C. fistula native to Khuzestan, Iran. MATERIALS AN...

recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of bacterial resistance to antimicrobial agents in chemical.the aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on escherichia coli. gold nanoparticles are chemically synthesized. standard strain of e. coli was cultured in a nutrient broth. minimum ...

The oil obtained from Sida cordifolia seeds were found to possess anti microbial activity against E. coli, Staphylococcus aureus, Candida albicans and Aspergillus niger by using cup-plate method This property was comparable with standard drug norfloxacin and griseofulvin disc. Petroleum ether extract of Sida cordifolia seeds also possess anti-inflammatory activity against carrageenan induced pa...

BACKGROUND A plant mixture containing indigenous Australian plants was examined for synergistic antimicrobial activity using selected test microorganisms. This study aims to investigate antibacterial activities, antioxidant potential and the content of phenolic compounds in aqueous, ethanolic and peptide extracts of plant mixture. METHODS Well diffusion, minimum inhibitory concentration (MIC)...
