BACKGROUND Chronic suppurative otitis media (CSOM) causes ear discharge and impairs hearing. OBJECTIVES To compare systemic antibiotics and topical antiseptics or antibiotics (excluding steroids) for treating chronically discharging ears with an underlying eardrum perforation (CSOM). SEARCH STRATEGY The Cochrane ENT Disorders Group Specialised Register, Cochrane Central Register of Controll...

A method of on-line pretreatment coupled to HPLC with fluorescence detection was developed and validated for the determination of nine quinolones in honey samples. This method simplified the complicated process of sample pretreatment and reduced sample treatment time. Recovery of the quinolones was between 92% 101% for spiked honey samples. The limit of detection was 0.22 3.78 ng/mL (signal/noi...

This study focused on the presence and distribution of 22 antibiotics, including eight quinolones, nine sulfonamides and five macrolides in mollusks from the Bohai Sea of China. 190 samples of eleven species were collected in 2006, 2007 and 2009. Laboratory analyses revealed that antibiotics were widely distributed in the mollusks with quinolones as the major compounds with concentrations of 0....

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-...

Following the first outbreaks of legionnaire’s disease, erythromycin emerged as the treatment of choice without the foundation of rigorous clinical trials. The number of therapeutic failures with erythromycin, as well as the side-effects and drug interactions, led to the consideration of other drugs such as the new macrolides and quinolones for the treatment of legionnaire’s disease in the 1990...

N-Sulfoconjugation is a common metabolic pathway of amine compounds in vivo. In the present study, we investigated the N-sulfation of quinolones and other amine drugs (ciprofloxacin, moxifloxacin, garenoxacin, desipramine, and metoclopramide) to assess the contribution of specific human cytosolic sulfotransferases (SULTs) to the reactions using purified recombinant enzymes and human liver cytos...

Quinolones are considered as a big family of multi-faceted drugs; their chemical synthesis is flexible and can be easily adapted to prepare new congeners with rationally devised structures. This is shown by the description of many thousands of derivatives in the literature. Scientists could accurately describe their QSAR, which is essential for effective drug design. This also gave them the cha...
