BACKGROUND The common usage of chewing sticks prepared from Neem tree (Azadirachta indica) in India suggests its potential efficacy in periodontal diseases. The objective of this study is to explore the antibacterial effects of Neem leaf extract on the periodontophatic bacteria Porphyromonas gingivalis and Fusobacterium nucleatum, and its antioxidant capacities alone and in combination with bac...

Knowledge of the synergic properties of staphylococcus toxin is comparatively recent: in 1933 Dr. E. L. Burky observed in rabbits immunized with staphylococcus toxin a reaction to the broth in which the toxin had been produced. In explanation he suggested that the "growth activities of the staphylococci had separated from the medium some substance which, when attached to the toxin, became antig...

The hypophyseal substance-the synergic factor-which gives increased gonadotropic effects when combined with prolan has been shown to itself possess a definite though slight gonadotropic activity. It produces transitory follicular enlargement within 24-48 hours, which, however, regresses at once on cessation of treatment so that by the end of the 4th day the ovary again approximates its infantil...

the external and interlamellar spaces of montmorilonite (mmt) were used as solid support for synthesis of cuo nanoparticles (nps) at room temperature by the chemical reduction method. in this project, copper nitrate plus water (cu(no3)2. xh2o) and sodium hydroxide (naoh) were used as copper precursor and reducing agent respectively. then, mmt/cu2+ nanocomposites were stabilized with different r...

conclusions probable mechanism of suppression of energy generation is suppression of the rise in glucose. results listeria monocytogenes was controlled using 2 mm of osthole. treatment of l. monocytogenes by 2 mm osthole had no effect on the atp level. objectives osthole has antibacterial properties, but its mechanisms of action is still unknown. materials and methods two millimoles of osthole ...

quinolones are a very important family of antibacterial agents that are widely prescribed for the treatment of infections in humans. since their discovery in the early 1960s, the quinolone group of antibacterials has generated considerable clinical and scientific interest. two major groups of compounds have been developed from the basic molecule: quinolones and naphthyridones. the 4-pyridone-3-...

during the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. in this study, the antibacterial activity of methanolic extract of t. pubescens (rich i...
