APPLIED RESEARCH Completed studies Studies on sputum transported in cetyl pyridinium chloride for detection of M. tuberculosis Background Drug resistance surveys require transportation of sputum samples collected from pulmonary TB patients in cetyl pyridinium chloride (CPC) solution to the reference laboratory for bacteriological investigations. It was observed that smears from sputum transport...

in this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (cpc) in pharmaceutical products using cloud point extraction (cpe) technique. the method is based on cloud point extraction of the cpc in alkali conditions using of nonionic surfactant triton x-114. under selected conditions, the calibration ...

BACKGROUND The relationships between chronic productive cough (CPC), environmental tobacco smoke (ETS) exposure, and asthma are not clearly established in children. Therefore, we wished to determine the prevalence of CPC and examine the relationships between CPC, ETS exposure, and asthma in young teenagers. METHODS We performed a cross sectional survey of 2397 Seattle middle school students, ...

Much progress has been made in the provision of palliative care across sub-Saharan Africa, however much still remains to be done, particularly in the area of children's palliative care (CPC). The Beacon Centres programme was set up in 2009, aimed at improving access to CPC in South Africa, Uganda and Tanzania through more and better-trained health professionals and CPC clinical services of a hi...

Calcium phosphate cement (CPC) that is based on α-tricalcium phosphate (α-TCP) is considered desirable for bone tissue engineering because of its relatively rapid degradation properties. However, such cement is relatively weak, restricting its use to areas of low mechanical stress. Wollastonite fibers (WF) have been used to improve the mechanical strength of biomaterials. However, the biologica...

Several materials have been used as drug delivery systems to maintain a high concentration of anticancer drugs at localized sites. The feasibility of using doxorubicin-loaded calcium phosphate cement (CPC) as a new material, which can release the drug as well as fill a postoperative bony defect, was investigated. The mechanical strength of cylinders of doxorubicin-loaded CPC was not lower than ...

The effects of chlorphenesin carbamate (CPC) and mephenesin on spinal neurons were investigated in spinal rats. CPC (50 mg/kg i.v.) inhibited the mono-(MSR) and poly-synaptic reflex (PSR), the latter being more susceptible than the former to CPC depression. Mephenesin also inhibited MSR and PSR, though the effects were short in duration. CPC had no effect on the dorsal root potential evoked by ...

The aim of this in vitro study was to determine the maximum inhibitory dilution (MID) of four cetylpyridinium chloride (CPC)-based mouthwashes: CPC+Propolis, CPC+Malva, CPC+Eucaliptol+Juá+Romã+Propolis (Natural Honey) and CPC (Cepacol), against 28 Staphylococcus aureus field strains, using the agar dilution method. Decimal dilutions ranging from 1/10 to 1/655,360 were prepared and added to Muel...

Objective To determine whether the antimicrobial nature of a fatty acid chelate temporary dental cement can be enhanced by the addition of 5% cetyl pyridinium chloride (CPC). Materials and methods The temporary cement, Cavex Temporary was employed, and additions of CPC were made to either the base or the catalyst paste prior to mixing the cement. Release of CPC from set cement specimens was fol...
