Antibacterial properties of hexane, chloroform and aqueous extracts of roots of Acorus calamus, Aristolochia indica, Cyperus rotundus, Desmodium gangeticum, Holostemma ada- kodien and Kaempferia galanga, used in the traditional medicine were studied on Bacillus pumilis and Eschericia coli by disc diffusion method.
nigella sativa seeds have wide therapeutic effects and have been reported to have significant effects against many ailments such as skin diseases, jaundice, gastrointestinal problems, anorexia, conjunctivitis, dyspepsia, rheumatism, diabetes, hypertension, intrinsic hemorrhage, paralysis, amenorrhea, anorexia, asthma, cough, bronchitis, headache, fever, influenza and eczema. thymoquinone (tq) i...
Antimicrobial activity was detected in the 50% ethanolic extract of Ixora coccinea. The effective inhibitory concentration of the extract against both the bacterial test organisms and the fungal test organisms studied was 125 ug mL(-1), beyond which the inhibitory activity declined and the organisms started reviving from the effect of the antimicrobial principle.
The aim of this study was to develop, characterize and assess the biological activity of a new regenerative 3D matrix with antimicrobial properties, based on collagen (COLL), hydroxyapatite (HAp), β-cyclodextrin (β-CD) and usnic acid (UA). The prepared 3D matrix was characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared Microscopy (FT-IRM), Transmission Electron Microsc...
Nanosilver (nAg) was prepared via Tollens method using dextrin as stabilizer. The morphology, size distribution and average size of the obtained nAg were characterized using Transmission electron microscope (TEM) and Dynamic light scattering (DLS) technique. A kinetic study of toxicity of nAg on Escherichia coli (E. coli) was determined. The obtained results showed that nAg exhibits spheric sha...
The antimicrobial properties of preterm and term breast milk cells were compared. They were similar in cell numbers and in the capacity to phagocytose and kill staphylococci. Interferon production on endotoxin challenge appeared to be higher in preterm cells. The antibacterial activity of breast milk cells was retained after storage at 4 degrees C for 24-48 hours. Cell numbers were unaffected b...
Introduction Iodine and iodinated resin have been evaluated for water treatment. Iodine (2.5-7.0 mg/l water) has been used in water treatment since 1900, especially for troops. Iodine’s solubility in water depends on temperature (0.29 g/1 at 20°C, 0.78 g/l at 50°C and 4.45 g/1 at 100°C). Its hydrolysis and hence speciation in water depends on pH and concentration of titrable iodine in solution....
background & aim: nowadays, the application of traditional medicine and herbal medicinal plants instead of chemical and synthetic drugs has captured the attention of the researchers. the purpose of this study was to investigate the antimicrobial effects of the aquatic, ethanolic and methanolic (80%) extracts of the aerial and root parts of stachys lavandulifolia vahl which were taken from t...
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...
improvement of the physical and mechanical properties of paper in the discussion of the application is very important. in order to fulfill this purpose, conventional processing techniques such as filtering and addition of long fibers and other chemicals such as additive resistors for dry and wet the pulp have been used. one of the methods to improve the physical and mechanical properties of pap...
