Background and Objective: Extreme use of antibiotics and discharging to the environment lead to serious consequences. Mesoporous silica such as MCM-41 material is widely used to absorb contaminants from the aqueous solution. The aim of this study was to evaluate mesoporous synthesis of MCM-41 and its efficacy for removal of the antibiotic cephalexin from aqueous solution. Materials and Methods...
Background and aim: For prevention of accidents in chemical processes, the use of multiple layers of protection is essential. In this regard, the analysis of adequacy and use of protective layer resistance is a necessity. In this study the level of protection layers security of Cephalexin Crystals production unit of one the pharmaceutical companies is examined. Methods: In this descriptive s...
Charcoal-horse blood agar with 40 micrograms of cephalexin per ml, charcoal-horse blood agar with 3 micrograms of lincomycin per ml, charcoal agar with 3 micrograms of lincomycin per ml, and Legionella (buffered charcoal-yeast extract) agar with 3 micrograms of lincomycin per ml were compared for isolation of Bordetella pertussis. Charcoal-horse blood agar with 40 micrograms of cephalexin per m...
The activity of eight antimicrobial agents was determined against 115 isolates of Staphylococcus saprophyticus. All were susceptible to ampicillin, cephalexin, and trimethoprim-sulfamethoxazole and resistant to nalidixic acid and novobiocin. A bimodal pattern of susceptibility to erythromycin was observed: 80% were inhibited by 0.25 microgram/ml, whereas 13% required greater than or equal to 12...
The in vitro susceptibility of 155 strains of anaerobic bacteria to five cephalosporin antibiotics was tested. Cefoxitin was the most active against 33 isolates of Bacteroides fragilis; 82% of the strains were sensitive at 16 mug/ml. At 64 mug/ml cefazolin and cephaloridine were also generally effective. Cephalothin and cephalexin were relatively inactive versus B. fragilis. Cefoxitin, cephalor...
This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%). In 13.7% of the cases, the coagulase-negativ...
Eighteen patients with urinary tract infection were treated with cephalexin orally. Absorption was variable, between 29 and 89% of the total daily dose being excreted in the urine in 24 hours. A significant number of patients became faecal carriers of Pseudomonas aeruginosa compared with a control group who received no antibiotics. Four of the cephalexin-treated patients acquired a strain of Ps...
Statement of Problem: One of the most important complications after tooth extraction and oral and maxillofacial surgery is transient bacteraemia and prescription of prophylactic antibiotic is necessary to prevent postoperative infections in immunocompromised patients. Purpose: The aim of this study was the evaluation of cephalexin and amoxicillin concentrations in dental alveolar sockets follow...
In vitro evaluation of the new oral cephalosporin cefatrizine: comparison with other cephalosporins.
Cefatrizine (BL-S640), a semisynthetic, orally administered cephalosporin, was found to have an in vitro spectrum of activity comparable to those of four other cephalosporins tested. It is as effective as cephalexin, the other orally administered cephalosporin evaluated, against most species, and it appears to be more effective than cephalexin against many Enterobacter, Haemophilus, and Proteus...
Various surfactant modified silica layers were used for the chromatography of five different Cephalosporins. The 4% methanolic CTAB impregnated silica layer was useful for the chromatography of Cephalosporins. The acidic buffer solvent systems were used with the 4% methanolic CTAB impregnated silica layers for the separation of different mixtures [A (Cefaclor, Ceftriaxone and Cefadroxil), B (Ce...
