Heliopsis longipes extract and affinin were not toxic as a reduction in the number of His⁺ revertant bacteria colonies. Affinin (25 and 50 µg/plate) significantly reduced the frameshift mutations that were generated by 2-aminoanthracene (2AA) (40%) and reduced the oxidative DNA damage generated by norfloxacin (NOR) (37-50%). Affinin possessed antioxidant properties that were able to reduce 2AA- and NOR-induced mutations in S. typhimurium TA98 and TA102, respectively.

The susceptibility of 11 clinical isolates of Mycobacterium tuberculosis, 3 M. kansasii, 3 M. xenopi, 2 M. scrofulaceum, 2 M. marinum, 2 M. malmoense to fleroxacin, ciprofloxacin, norfloxacin, rifampicin, isoniazid, ethambutol, and streptomycin was determined by the standard proportion method (Middlebrook 7H10 agar). All M. tuberculosis, M. kansasii, M. xenopi, M. scrofulaceum, M. marinum, and M, malmoense isolates including those resistant to conventional antimycobacterials were inhibited by 0.5 mg/l of fleroxacin and ciprofloxacin, the lowest tested concentration. Fleroxacin and ciprofloxacin along with ofloxacin, pefloxacin, ansamycin, clofazimine and cycloserine were also tested against 14 isolates of the M. avium complex. Nine of 14 strains (64%) of the M. avium complex were found susceptible to 4 mg/l of fleroxacin and a similar percentage to the other quinolones. On the basis of its in-vitro potency and its favourable pharmacokinetic properties fleroxacin appears to be sufficiently active to warrant further experimental trials against difficult to treat mycobacteria.

Liver injury due to idiosyncratic drug reactions can be difficult to diagnose and may lead to acute liver failure (ALF), which has a high mortality rate. N-acetylcysteine (NAC) is effective treatment for paracetamol toxicity, but its role in non-paracetamol drug-induced ALF is controversial. We report on the use of a validated bedside tool to establish causality for drug-induced liver injury (DILI) and describe the first case of resolution of norfloxacin-induced ALF after NAC therapy. NAC is easy to administer and generally has a good safety profile. We discuss the evidence to support the use of NAC in ALF secondary to DILI and possibilities for further clinical research in this field.

The general lack of knowledge about the health effects of waterpipe smoking is among the reasons for its global spread. In this study, bacterial contamination of waterpipe hoses was investigated. Twenty hoses were collected from waterpipe cafés and screened for bacterial pathogens using standard culture and isolation techniques. Additionally, resistance of isolated bacteria to common antibiotics was determined by identifying the minimum inhibitory concentration (MIC) of each isolate. Forty eight bacterial isolates were detected. Isolates included both Gram-positive and Gram-negative pathogens from species that included Micrococcus (12), Corynebacterium (13) and Bacillus (9). In addition, some of the detected pathogens were found to be resistant to aztreonam (79%), cefixime (79%), norfloxacin, amoxicillin (47%), clarithromycin (46%) and enrofloxacin (38%). In conclusion, the hose of the waterpipe device is a good environment for the growth of bacterial pathogens, which can then be transmitted to users.

The in vitro and in vivo activity of ofloxacin (DL 8280, HOE 280) was compared with that of other antibacterial compounds. Ofloxacin was found to have a broad antibacterial spectrum which includes both gram-positive and gram-negative aerobic and anaerobic species. Its activity is generally higher than that of pipemidic acid and nalidixic acid. Against staphylococci and streptococci, ofloxacin proved to be more active than norfloxacin. In the case of Enterobacteriaceae and Pseudomonadaceae, ofloxacin and norfloxacin possess comparable activities. Ofloxacin was the most active compound against a number of aerobic isolates which are resistant to cefotaxime and ceftriaxone. Of the compounds compared, ofloxacin was the only one which exhibited reasonable activity against anaerobes. It inhibited all strains of Bacteroides fragilis at a concentration of 3.125 mg/l and the gram-positive anaerobes at 0.5 mg/l. In mice experimentally infected with various gram-positive and gram-negative bacteria, ofloxacin was more active than norfloxacin and pipemidic acid. With the gram-negative pathogens, orally administered ofloxacin was as active as gentamicin used parenterally. We conclude from our studies that ofloxacin could be a valuable therapeutic agent with a variety of indications.

Three clinical isolates of N gonorrhoeae susceptible to norfloxacin were exposed to increasing concentrations of norfloxacin. To identify mutations in the gyrA and parC genes of the gonococcal mutants, the quinolone resistance determining regions of the gyrA and parC genes were polymerase chain reaction (PCR) amplified and the PCR products were directly sequenced. Norfloxacin accumulation in the gonococcal cells was also measured.

The interaction between pefloxacin, ciprofloxacin, norfloxacin, and ofloxacin and biofilms formed by Staphylococcus epidermidis (20 clinical isolates) was studied. In the presence of 1/2-MIC and 1/8-MIC of quinolones, the optical density of the biofilms was reduced to 22-24% and 65-74% of the controls, respectively. Treatment of preformed biofilms with quinolones in concentrations ranging from 12.5 microg/ml to 400 microg/mL caused reduction in the optical density of the adherent biofilms to 45-77% of the control. In an in vitro model of vascular catheter colonization, subinhibitory concentrations (12, 14 and 1/8 MIC) of fluoroquinolones reduced the number of adherent bacteria to 24-28%, 48-55% and 58-76% of the controls, respectively. The vascular catheter segments precolonized with Staphylococcus epidermidis for 24 h and exposed to the fluoroquinolones in 8-16 times MIC (100 microg/mL) for 2 h showed no growth of adherent cells. The activity of pefloxacin in reducing the bacterial adhesion and eradicating the preformed biofilms was demonstrated by scanning electron microscope. These data show that subinhibitory concentrations of ciprofloxacin, norfloxacin, pefloxacin, and ofloxacin inhibit the adhesion of Staphylococcus epidermidis to plastic surfaces and vascular catheters. Higher concentrations of fluoroquinolones were able to eradicate the preformed biofilms on vascular catheters.

A highly effective analytical method for multi-residue determination of antibiotics in aquifer sediments was first established in this study. Microwave-assisted solvent extraction (MASE) and solid-phase extraction were used for sample pre-concentration and purification, ultra-high performance liquid chromatography coupled to hybrid quadrupole-high resolution Orbitrap mass spectrometry (UHPLC-Q-Orbitrap) was applied for detection. For high resolution mass spectrometry (HRMS), the target compounds were tentatively identified by retention time and accurate mass which was measured with precursor ions in Target-SIM scan, and then confirmed by the monitoring of daughter ion fragments which were generated in dd-MS(2) scan. The results provided good mass accuracy with mass deviations below 2ppm (except norfloxacin with -2.3ppm) for quantitative analysis of the compounds by HRMS. Reasonable recoveries of all analytes were obtained more than 60% (except doxytetracycline) in fortification samples at concentrations higher than 10μgkg(-1). Relative standard deviations of repeatability and inter-day precision were below 21% and 11%. Limits of detection (LOD) ranged from 0.1 to 3.8μgkg(-1), whereas limits of quantification (LOQ) were established between 0.3-9.0μgkg(-1). The method was applied to analyze real aquifer sediment samples in different aquifer depth of 4.0, 7.5, 13.0 and 18.0m. Chlorotetracycline and ofloxacin were observed at relative high concentrations of 53 and 19μgkg(-1) respectively in 18.0m deepness. The exposure to low doses of these compounds in subsurface environment increases concerns on long-term ecological security of underground system.

Emergency of multi-drug resistance in Pseudomonas aeruginosa isolates after exposure to gentamicin was investigated with reference to their LPS-compositions. Three strains each of P. aeruginosa, different in LPS-compositions (long- and short-LPS strains, and LPS-deficient strain) were once or repeatedly incubated overnight at 35 degrees C in Mueller-Hinton broth including different concentrations of gentamicin, a poly-cationic antibiotic. LPS-compositions of the bacteria which survived and were grown after exposure to gentamicin were analyzed and the susceptibility to some of anti-pseudomonal drugs was determined. Of the test 9 strains after single exposure, No. 4 (long-LPS) and No. 41 (short-LPS) formed the LPS-deficient mutants. The resistance to ceftazidime and gentamicin was found in No. 4 strain, but not in No. 41 strain. Drug resistance in different patterns was also found in Nos. 43, 29, 45 and 52 strains without any change in their LPS-compositions. Contrary to these results, the susceptibility to norflxacin increased in Nos. 21 and 45 strains without any change in their LPS-compositions. After repeated exposures to gentamicin, the LPS-compositions of Nos. 4 and 14 (short-LPS) were altered and formed the LPS-deficient and the Intermediate-LPS (between short and long compositions) mutants, respectively. The LPS-alteration in both strains were accompanied by the development of resistance to ceftazidime and gentamicin, respectively. The drug resistance in different patterns were also found in Nos. 43, 156, 29, 41, 21, 45 and 52 strains, without any change in the LPS-compositions, whereas the increase in susceptibility to norfloxacin was simultaneously found in No. 45 strain. The ionic-binding of [3H]-gentamicin to the cell surfaces of two LPS-deficient mutants of P. aeruginosa decreased markedly, in comparison with that of the respective parents, and these results might lead to the drug resistance in the LPS-deficient mutants. However, the gentamicin-induced resistance of some strains of P. aeruginosa (but no change in the LPS-compositions) to the test drugs including gentamicin indicates a possibility that negative charges on the bacterial surface were decreased by the drug exposure. The drug resistance and LPS-compositions in the gentamicin-induced mutants of P. aeruginosa were stable during or after the 15th in vitro serial transfers.

This cross-sectional study was conducted in a teaching hospital outside the city of Ujjain in India. Seven antibiotics--amoxicillin, ceftriaxone, amikacin, ofloxacin, ciprofloxacin, norfloxacin and levofloxacin--were selected. Prescribed quantities were obtained from hospital records. The samples of the hospital associated water were analysed for the above mentioned antibiotics using well developed and validated liquid chromatography/tandem mass spectrometry technique after selectively isolating the analytes from the matrix using solid phase extraction. Escherichia coli isolates from these waters were tested for antibiotic susceptibility, by standard Kirby Bauer disc diffusion method using Clinical and Laboratory Standard Institute breakpoints.

This study investigated the species distribution and antimicrobial resistance among 99 enterococci isolated from hospitalized patients in 12 hospitals in Cuba from October 2000 to September 2001. Species identification was performed by WIDER Automatic System (Francisco Soria Melguizo, Madrid, Spain), and the susceptibility testing was performed by disk diffusion, agar dilution, and E-test methods. Enterococcus faecalis was the most prevalent (85%) species, followed by E. faecium (10%), E. gallinarum (2%), E. casseliflavus (2%), and E. durans-hirae (1%). A higher percentage of resistance to ampicillin (50%), fosfomycin (40%), ciprofloxacin (30%), norfloxacin (20%), and tetracycline (90%) was detected in E. faecium isolates, whereas E. faecalis strains showed higher rates of resistance to erythromycin (52.4%), chloramphenicol (34.5%), rifampicin (62.5%), moxifloxacin (3%), and nitrofurantoin (2.4%). Resistance to glycopeptide was detected in E. faecalis (1.2%) and E. faecium (10%). Thirty-one E. faecalis (37%) and 3 E. faecium (30%) showed a high-level resistance to gentamicin. The results of this work will be very helpful to guide empirical antimicrobial therapy and the implementation of infection control measures in Cuban hospitals.

The fluoroquinolone compounds, such as ciprofloxacin, norfloxacin, and ofloxacin, have broad spectrum bactericidal activity and have proved to be effective in both the treatment and prevention of certain infections in patients with cancer. The triazole drug fluconazole is useful in the treatment of oral, esophageal, and disseminated candidiasis and cryptococcal meningitis. Early studies suggest that a new acyclic nucleoside, ganciclovir, has some effect in the treatment of cytomegalovirus infections, but its precise use in patients with cancer has not been fully established.

Though O157 can cause a life-threatening diseases, the therapeutic protocol using antibiotics for the infection is still controversial. Main reasons for hesitating the uses of antibiotics for the infection is their possibility to enhance the release of verotoxins (VT). We have recently established the mouse model of O157 infection using germfree mice. Using this animal model of O157 infection, we examined therapeutic efficacy of antibiotics. Fosfomycin (FOM) and norfloxacin (NFLX) were selected for in vivo examination, because of their lower MIC under anaerobic condition (MIC:FOM = 0.78; NFLX = 0.10 microgram/ml) than those of the other antibiotics including kanamycin, doxycycline, minocycline, choramphenicol, cefaclor and ampicilin. When germfree BALB/c mice were orally infected with 1 x 10(5)CFU of O157 (clinically-isolated strain, TI001) at day 0, all mice died at 8 to 9 d after the infection. Oral treatment of the mice with FOM (500 mg/kg/d, twice a day) or NFLX (50 mg/kg/d, twice a day) everyday for 5 days starting at 3 hr after the infection significantly improved the survival rate from 0% to 83.3%, and 100%, respectively. VT could not be detected in the feces of the mice in either groups, suggesting that neither of these antibiotics enhanced the release of VT. Interestingly, when FOM treatment was started at 3, 6, 12 or 24 hr after the infection, the survival rate was 100%, 100%, 0% and 0%, respectively. Thus, in conclusion, FOM and NFLX are both useful as the therapeutic agents for O157 infection. However, the treatment should be started in the early phase after the infection.

Norfloxacin is more effective and less costly than the alternative, TMP-SMX. Norfloxacin treatment will save $195.85 per patient, resulting in an aggregate saving of more than $40 million annually. Patients are expected to enjoy a better quality of life with an incremental 0.0601 QALD per patient, if they are treated with norfloxacin. These results are robust across a wide range of probabilities and costs.

The efficacy and safety of 7-10-day courses of lomefloxacin (single daily dose of 400 mg) or norfloxacin (twice-daily doses of 400 mg) for the treatment of uncomplicated urinary tract infections were compared in two large, multicenter, randomized trials. This article presents the combined results of these trials, which were conducted in a total of 27 centers throughout the United States. A total of 727 adults, mostly women, with symptoms of acute urinary tract infection were enrolled; 370 patients were randomized to lomefloxacin treatment, and 357 received norfloxacin. The bacteriologic cure rate at 5-9 days post-therapy was 98.2% in the lomefloxacin group and 96.3% in the norfloxacin group (p = nonsignificant). The clinical success rate of 99.1% in the lomefloxacin group was significantly higher than the success rate of 93.5% in the norfloxacin group (p = 0.002). Adverse events were reported by 157 lomefloxacin-treated patients and 129 patients receiving norfloxacin. Adverse events attributable to drug treatment occurred in 41 patients (11.1%) in the lomefloxacin group and 27 (7.6%) in the norfloxacin group. Eight lomefloxacin (2.2%) and three norfloxacin patients (0.8%) were withdrawn from treatment because of adverse events probably attributable to the drug. The incidence of dizziness, tremor, and photosensitivity rash was higher in the lomefloxacin group than in the norfloxacin group, while the incidence of nausea was higher in the norfloxacin group. The results of these trials demonstrate that once-daily administration of 400 mg lomefloxacin is as safe and effective clinically as, and superior bacteriologically to, twice-daily administration of 400 mg norfloxacin in the treatment of acute uncomplicated urinary tract infections in adult patients.

A sensitive, selective, and efficient method was developed for simultaneous determination of 11 fluoroquinolones (FQs), ciprofloxacin, danofloxacin, difloxacin, enrofloxacin, flumequine, marbofloxacin, norfloxacin, ofloxacin, oxolinic acid, pipemidic acid, and sarafloxacin, in eggs by molecularly imprinted polymer (MIP) and column liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Samples were diluted with 50 mM sodium dihydrogen phosphate at pH 7.4, followed by purification with a commercial MIP (SupelMIP SPE-Fluoroquinolones). Recoveries for the 11 quinolones were in the range of 90-106% with intra- and interday relative standard deviation ranging from 1 to 6% and from 3 to 8%, respectively. Limits of detection (LODs) were 0.12-0.85 ng/g, and limits of quantification (LOQs) were 0.36 and 2.59 ng/g, whereas the decision limit (CC(α)) and detection capability (CC(β)) ranged from 0.46 to 3.35 ng/g and from 0.59 to 4.12 ng/g, respectively. The calculated relevant validation parameters are in an acceptable range and in compliance with the requirements of Commission Decision 2002/657/EC. Moreover, a comparison to two other sample treatments [solid-phase extraction (SPE) and solvent extraction] has been carried out. The method was applied to lying hens, Japanese quail, and black-headed gull eggs, in which FQs were not found. The method was also applied to study the depletion of sarafloxacin in eggs.

MK-0366, a new derivative of nalidixic acid, was buy noroxin tested against 250 urinary pathogens including Escherichia coli, Serratia marcescens, and Pseudomonas aeruginosa. This new agent was more active than any of the other antibiotics tested, which included carbenicillin, ampicillin, cephalexin, tetracycline, trimethoprim, trimethoprim-sulfamethoxazole, and nalidixic acid. Gentamicin-resistant P. aeruginosa were highly sensitive to MK-0366, with a 90% minimal inhibitory concentration of 0.8 microgram/ml. Serratia strains were the most resistant organisms, with a 90% minimal inhibitory concentration of 3.1 micrograms/ml. These results suggest that clinical trials should be designed to investigate the clinical usefulness of this new drug in urinary infections.

Twenty-eight strains of Pseudomonas aeruginosa with various degrees of norfloxacin resistance were isolated from patients with urinary tract infections. P. aeruginosa strains (norfloxacin MICs, 3.13 to 200 micrograms/ml) were transformed by either pPAW207 or pNF111 plasmid DNA, which included either the gyrA or nfxB gene, respectively. For transformants with pPAW207, norfloxacin MICs decreased 8- to 128-fold. It was suggested that moderate buy noroxin and high degrees of resistance to norfloxacin were expressed as a result of alterations in gyrA. No strain manifesting only an alteration in nfxB permeability was observed. The MICs of norfloxacin (200 micrograms/ml) for two P. aeruginosa strains, GN17605 and GN17434-2, were decreased following transformation not only by pPAW207 but also by pNF111. Analysis of outer membrane proteins disclosed the presence of a 54,000-Da protein in these parent strains that was not expressed in the pNF111 transformants. The level of accumulation of norfloxacin by the pNF111 transformant of GN17605 was higher than that by the parent strain. The norfloxacin susceptibility of DNA gyrase subunit A purified from GN17605 was only 1/35th that of the gyrase containing a subunit A from P. aeruginosa PAO1. These findings suggest that GN17605 is a gyrA-nfxB double mutant and that strain GN17434-2 possesses double mutations in both nfxB and some unknown gene.

Among the 594 patients examined, 158 were HIV+ D+, 121 were HIV2 D+, 160 were HIV+ D , and 155 were HIV D . The main etiologies of diarrhea were different according to HIV serostatus of patients. In immunocompetent adults the main causes of diarrhea were Shigella sp (12.4%), Entamoeba histolytica(10.7%), Salmonella enterica (6.6%), and Giardia (4.9%). In the immunocompromised host the more frequent pathogens were enteroaggregative E. coli (19.6%), Microsporidium (9.4%), Cryptosporidium sp (8.2%), Rotavirus (8.2%), Shigella sp (7.6%), Candida albicans (7.6%), E. histolytica (5.1%), S. enterica (4.4%), and Isospora belli (4.4%). Also, Blastocystis hominis has to be considered as an opportunistic parasite, buy noroxin because it was identified only in HIV-infected patients, with higher prevalence in adults with diarrhea (2.5% in HIV+ D+ patients; 0.6% in HIV+ D patients). High level of asymptomatic carriage of Ascaris lumbricoides and Trichuris trichiura and some cases of multiple infections were observed. Fungi, Cryptosporidium sp and Microsporidium sp, were often identified in patients with low CD4 counts (range, 79 250 cells/mL). Independently from HIV-serostatus, CD4 count was lower in diarrheic persons, suggesting that diarrhea is a debilitating illness and that effective management of diarrhea can prevent immunosuppression. Isolated enteropathogenic strains displayed high resistance to most antibiotics used in Senegal for treating diarrhea (ampicillin, tetracycline, cotrimoxazole); they were susceptible to amikacin, gentamicin, and norfloxacin.

Ciprofloxacin was the highest prescribed antibiotic in the hospital and its residue levels in the hospital wastewater were also the highest. In samples of the municipal water supply and the groundwater, no antibiotics were detected. There was a positive correlation between the quantity of antibiotics prescribed in the hospital and antibiotic residue levels in the hospital wastewater. Wastewater samples collected in the afternoon contained both a higher number and higher levels of antibiotics compared to samples buy noroxin collected in the morning hours. No amikacin was found in the wastewater, but E.coli isolates from all wastewater samples were resistant to amikacin. Although ciprofloxacin was the most prevalent antibiotic detected in the wastewater, E.coli was not resistant to it.

Tigemonam, an oral monobactam that exhibits beta-lactamase stability similar to that of aztreonam, was tested in vitro against 240 species of Enterobacteriaceae (50 Escherichia coli, 48 Klebsiella pneumoniae, 52 Enterobacter cloacae, 32 Proteus mirabilis, 22 Proteus indole-positive [Providencia sp.], 24 buy noroxin Serratia sp., and 12 Citrobacter sp. All strains were resistant to ampicillin and first-generation cephalosporins. In addition, 77.4% were resistant to amoxicillin plus clavulanic acid, 46.8% to cefuroxime, 23.3% to ceftriaxone, 22.2% to aztreonam, 46.9% to cotrimoxazole, and 0.9% to norfloxacin. Tigemonam at a concentration of 4 micrograms/mL or less inhibited 72.7% of the strains with minimum inhibitory concentrations ranging from 0.03 or less to more than 512 micrograms/mL. The highest intrinsic activity was observed against Proteus sp. Tigemonam proved to be a bactericidal antibiotic. Cross-resistance was chiefly observed with aztreonam and ceftriaxone. It is concluded that tigemonam should play an important role in the treatment of nosocomial infections that do not require parenteral therapy and in the treatment of multiresistant community-acquired infections.

The third generation quinolones, ciprofloxacin, enoxacin, fleroxacin, norfloxacin, ofloxacin and pefloxacin are all quickly and quantitatively well (75-95% of an oral dose) absorbed upon oral administration. The maximum serum concentrations appear after 1-2 hours. The serum and urine concentrations after oral or intravenous ciprofloxacin are directly proportional with the doses and follow normal, dose-independent pharmacokinetics. Ciprofloxacin and norfloxacin reach the same serum levels after the same doses. Steady-state levels are indifferent from those after the first dose. In contrast, enoxacin, oflaxacin and pefloxacin do reach somewhat higher levels after chronic administration. Ciprofloxacin is eliminated by the kidneys (active tubular secretion which is blocked by probenecid) (60% after an intravenous administration), by metabolism and by the transintestinal route. Metabolism is minimal (ca. 15-20% for ciprofloxacin and norfloxacin). Transintestinal elimination implies that the drug is eliminated by transport across the intestinal wall without significant biliary elimination (which is less than 1%). buy noroxin Penetration into tissues occurs readily. Concentrations in prostate secretion are high for ciprofloxacin and norfloxacin. Ciprofloxacin reaches high intracellular concentrations; within human neutrophils the levels reach 6 times the concentrations in the surrounding fluid. Concentrations in bile and tissues are in general comparable to those in serum. Cerebrospinal fluid (CSF) concentrations are low when meningi are normal, but 40-90% of the serum levels when the meninges are inflamed. Because the transintestinal route of elimination compensates for loss of renal elimination, the serum half-life of ciprofloxacvin is raised only to 5-10 hours even in total renal failure.(ABSTRACT TRUNCATED AT 250 WORDS)

Our objective was to evaluate the relation between antimicrobial use and susceptibility in the intensive care unit (ICU) and non-ICU inpatient areas in the Bolzano regional hospital. For the isolates of S. aureus, coagulase negative staphylococci, Enterococcus sp., P. aeruginosa and E. coli we found a pattern of significant stepwise decrease in the frequency of antimicrobial susceptibility to penicilloic beta-lactam antibiotics and first generation cephalosporins; the highest senitivity rates occurred among isolates from outpatients, followed in decreasing order by rates among isolates from non-ICU inpatients and from ICU-patients; the rate of use of this group of antimicrobial agents was relatively high in the intensive care unit (13,1%). For P. aeruginosa we observed significantly lower susceptibility-rates to second, third and fourth generation cephalosporins, carbapenems and monobactams for non-ICU inpatient areas than for outpatient or ICU areas; this paralleled with the low use of this group of agents in the ICU area (4,9%). Also, for buy noroxin P. aeruginosa the prevalence of susceptibility to ciprofloxacin and norfloxacin in inpatient areas was lower than in the outpatient or ICU-areas; the rate of quinolone-use was relatively low in the ICU area (4,2%).

The construction of molecularly imprinted polymers on magnetic nanoparticles gives access to smart materials with dual functions of target recognition and magnetic separation. In this study, the superparamagnetic surface-molecularly imprinted nanoparticles were prepared via surface-initiated reversible addition-fragmentation chain transfer (RAFT) polymerization using ofloxacin (OFX) as template for the separation of fluoroquinolones (FQs). Benefiting from the living/controlled nature of RAFT reaction, distinct core-shell structure was successfully constructed. The highly uniform nanoscale MIP layer was homogeneously grafted on the surface of RAFT agent TTCA modified Fe3O4@SiO2 nanoparticles, which favors the fast mass transfer and rapid binding kinetics. The target binding assays demonstrate the desirable adsorption capacity and imprinting buy noroxin efficiency of Fe3O4@MIP. High selectivity of Fe3O4@MIP toward FQs (ofloxacin, pefloxacin, enrofloxacin, norfloxacin, and gatifloxacin) was exhibited by competitive binding assay. The Fe3O4@MIP nanoparticles were successfully applied for the direct enrichment of five FQs from human urine. The spiked human urine samples were determined and the recoveries ranging from 83.1 to 103.1% were obtained with RSD of 0.8-8.2% (n = 3). This work provides a versatile approach for the fabrication of well-defined MIP on nanomaterials for the analysis of complicated biosystems.

The presence of antibiotics including norfloxacin in the aquatic environment may cause adverse effects in non-target organisms. But the toxic mechanisms of fluoroquinolone to fish species are still not completely elucidated. Thus, it is essential to investigate the response of fish to the exposure of fluoroquinolone at molecular or cellular level for better and earlier prediction of these environmental pollutants toxicity. The sub-chronic toxic effects of norfloxacin (NOR) on swordtail fish (Xiphophoru s helleri) were investigated by measuring mRNA expression of cytochrome P450 1A (CYP1A), cytochrome P450 3A (CYP3A), glutathione S-transferase (GST) and P-glycoprotein (P-gp) and their corresponding enzyme activities (including ethoxyresorufin O-deethylase, erythromycin N-demethylase and GST. Results showed that NOR significantly affected the expression of CYP1A, CYP3A, GST and P-gp genes in swordtails. The gene expressions were more responsive to NOR exposure than their corresponding enzyme activities. Moreover, sexual differences were found in gene expression and enzyme activities of swordtails exposed to NOR. Females displayed more dramatic changes than males. The study further demonstrated that the combined biochemical and molecular parameters were considered as useful biomarkers to improve our understanding of potential ecotoxicological risks of buy noroxin NOR exposure to aquatic organisms.

A simple program has been developed for calculating areas under concentration-time curves with a home buy noroxin computer. Although it was primarily produced in BBC BASIC for the BBC microcomputer, an adaptation has been made to allow its use with a limited subset of BASIC commands on other computers. After the time and concentration data have been entered, the computer produces a smooth curve running through all data points and employs a spline-fitting interpolation technique to produce equally spaced points, as required by Simpson's rule which is used as the numerical integration procedure. The areas of the vertical strips so formed are then calculated and added together, the integration times being selected by the investigator himself. Comparison with a traditional method showed a good correlation, as did comparison with a commercial NONLIN program. The simple program allows a large number of observations to be analysed quickly, and has proved very useful in calculating AUC values in individual patients in studies with various new antimicrobial agents.

The in-vitro susceptibilities of 198 isolates of precisely identified Proteeae species to six quinolone antimicrobials were determined. Significant differences in susceptibility patterns among various Proteeae to the quinolones examined were demonstrated. Although Providencia stuartii was found to be the most resistant to buy noroxin quinolones including the very active agent ciprofloxacin, fully speciated Prov. rettgeri were also markedly resistant as well. in contrast Prov. alcalifaciens was extremely sensitive to these agents. Some strains of Proteus penneri were more resistant to the three newer compounds (ciprofloxacin, enoxacin and norfloxacin) than strains of Pr. vulgaris suggesting that recognition of this species may be important in surveys of the in-vitro activity of antibiotics. Pr. mirabilis and Morganella morganii were very sensitive to the newer agents. The patterns of resistance seen in the three newer agents were reflected in the older agents acrosoxacin and cinoxacin. Accurate speciation of Proteeae in surveys of susceptibilities to antimicrobial agents is important if misleading results are not to be reported.

Selective antimicrobial decontamination with norfloxacin was compared with vancomycin/polymyxin for prophylaxis of bacterial infections in granulocytopenic patients. In the group of patients receiving norfloxacin, there were a lower number of acquired gram-negative bacillary organisms per patient (0.88 versus 1.86, p = 0.002), fewer patients with documented infection (16 of 36 versus 20 of 30, p = 0.12), and fewer cases of gram-negative septicemia (0 of 36 versus five of 30, p = 0.02). Norfloxacin was better tolerated (30 of 36 versus 16 of 30 patients highly compliant, p = 0.02), and associated with fewer gastrointestinal side effects (eight of 36 versus 14 of 36 patients, p = 0.07). These results suggest that norfloxacin is Feldene Generic Name a more tolerable and efficacious oral antimicrobial agent than vancomycin/polymyxin for the prevention of serious gram-negative bacillary infections in granulocytopenic patients.

A direct, accurate, and sensitive chromatographic analytical method for the quantitative determination of five fluoroquinolones (enoxacin, ofloxacin, norfloxacin, ciprofloxacin, and enrofloxacin) in chicken whole blood is proposed in the present study. For quantitative determination lamotrigine was used as internal standard at a concentration of 20 ng/microL. The developed method was successfully applied to the determination of enrofloxacin, as the main component of commercially available veterinary drugs. Fluoroquinolone antibiotics were separated on an Inertsil (250 x 4 mm) C8, 5 microm, analytical column, at ambient temperature. The mobile phase consisted of a mixture of citric acid (0.4 mol L(-1))-CH3OH-CH3CN (87:9:4% v/v) leading to retention times less than 14 min, at a flow rate 1.4 mL min(-1). UV detection at 275 nm provided limits of detection of 2 ng/mL per 20 microL injected volume for enoxacin, norfloxacin, and ciprofloxacin, 0.4 ng/mL for ofloxacin, and 4 ng/mL for enrofloxacin. Preparation of chicken blood samples is based on the deproteinization with acetonitrile while the pharmaceutical drug was simply diluted with water. Peaks of examined analytes in real samples were identified by means of a photodiode array detector. The method was validated in terms of within-day (n=6) precision and accuracy after chicken whole blood sample deproteinization by CH3CN. Using 50 microL of chicken blood sample, recovery rates at fortification levels of 40, 60, and 80 ng ranged from Zofran Maximum Dosing 86.7% to 103.7%. The applicability of the method was evaluated using real samples from chicken under fluoroquinolone treatment.

Fosfomycin tromethamine is an oral antimicrobial indicated for the treatment of uncomplicated lower urinary tract infections (UTIs). This agent is active in the urine against common uropathogens that are associated with cystitis in women, including organisms resistant to other antibiotics. A single dose of fosfomycin tromethamine is well absorbed and produces a therapeutic concentration in the urine for one to three Pamelor Starting Dose days. Comparative clinical trials suggest that a single 3.0-g dose of fosfomycin tromethamine is as clinically effective as 7- to 10-day treatment regimens of standard agents such as nitrofurantoin, norfloxacin, and trimethoprim/sulfamethoxazole used to treat UTIs. Fosfomycin tromethamine is well tolerated and appears safe for use during pregnancy. Quality-of-life advantages, such as enhanced compliance and convenience, are also important aspects of fosfomycin tromethamine therapy.

The multi-residue procedure for basic drugs described elsewhere by this laboratory has been evaluated for quinolone and fluoroquinolone antibiotics. The fluoroquinolones are a relatively new class of drug and an increasing number of licensed products containing these compounds are becoming available for use in animal husbandry. This, along with the possibility of Botox Vial Cost the development of antibiotic resistant human pathogens, make it an important class of drug for which methodology is required for the monitoring of residues in food. Validation data are presented for a range of compounds including the quinolones; oxolinic acid and nalidixic acid, and the fluoroquinolones; flumequine, ciprofloxacin, danofloxacin, enoxacin, enrofloxacin, lomefloxacin, marbofloxacin, norfloxacin, ofloxacin and sarafloxacin. Foods for which the method was validated included poultry muscle (chicken and turkey), egg, chicken liver, honey, cattle muscle and pig muscle. This application of the multi-residue procedure further demonstrates the importance and wide-ranging usefulness of the technique.

The accumulation of ciprofloxacin, norfloxacin, moxifloxacin, levofloxacin and ofloxacin by Mycobacterium tuberculosis H37Rv was determined with a modified fluorescence method. The time to achieve a steady-state concentration (SSC) of each agent in M. tuberculosis was 60-240 s. Moxifloxacin was accumulated to the lowest concentration and ciprofloxacin to the highest. However, ciprofloxacin Tab Hytrin 1mg took longer to achieve an SSC than the other four agents; levofloxacin reached steady state in the shortest time. Larger fluoroquinolones accumulated to the lowest concentration and more slowly. Although all five agents had low hydrophobicity values (P(app) < or =0.11), those with the lowest values accumulated to the higher concentrations.

Twenty-six studies, involving 3033 patients, are included in this review.Fluoroquinolones versus older antibiotics (chloramphenicol, co-trimoxazole, amoxicillin and ampicillin)In one study from Pakistan in 2003-04, high clinical failure rates were seen with both chloramphenicol and co-trimoxazole, although resistance was not confirmed microbiologically. A seven-day course of either ciprofloxacin or ofloxacin were found to be superior. Older studies of these comparisons failed to show a difference (six trials, 361 participants).In small studies conducted almost two decades ago, the fluoroquinolones were demonstrated to have fewer clinical failures than ampicillin and amoxicillin (two trials, 90 participants, RR 0.11, 95% CI 0.02 to 0.57).Fluoroquinolones versus current second-line options (ceftriaxone, cefalexin, and azithromycin)The two studies comparing a seven day course of oral fluoroquinolones with three days of intravenous ceftriaxone were too small to detect important differences between antibiotics should they exist (two trials, 89 participants).In Pakistan in 2003-04, no clinical or microbiological failures were seen with seven days of either ciprofloxacin, ofloxacin or cefixime (one trial, 139 participants). In Nepal in 2005, gatifloxacin reduced clinical failure and relapse compared to cefixime, despite a high prevalence of NaR in the study population (one trial, 158 participants, RR 0.04, 95% CI 0.01 to 0.31).Compared to a seven day course of azithromycin, a seven day course of ofloxacin had a higher rate of clinical failures in populations with both multi-drug resistance (MDR) and nalidixic acid resistance (NaR) enteric fever in Vietnam in 1998-2002 (two trials, 213 participants, RR 2.20, 95% CI 1.23 to 3.94). However, a more recent study from Vietnam in 2004-05, detected no difference between gatifloxacin and azithromycin with both drugs performing well (one trial, 287 participants).

Effects of repeated oral administration of new quinolones, ofloxacin, enoxacin and norfloxacin, once daily for 7 days, on the drug-metabolizing enzyme system of rat hepatic microsomes were studied in comparison with that of phenobarbital, a potent inducer of cytochromes P-450. Treatment of phenobarbital at the oral dose of 120 mg/kg induced significant increases in the contents of cytochrome P-450, cytochrome b5 and NADPH-cytochrome P-450 reductase and in the activity of ethoxycoumarin O-deethylase, and significant decreases in the activities of benzphetamine N-demethylase and aniline hydroxylase. However, ofloxacin, enoxacin and norfloxacin at the oral dose levels of 80 and 320 mg/kg showed no significant effect on the content of each constituent of the drug-metabolizing enzyme system, and the three enzyme activities. Thus, it is concluded that new quinolones including ofloxacin have no ability to induce a cytochrome-P-450-dependent monooxygenase system.
