Disease relevance of CETYLPYRIDINIUM

• Adsorption of Salmonella enteritidis by cetylpyridinium-exchanged montmorillonite clays [1].
• A fragment of Micrococcus lysodeikticus cell-wall obtained by cetylpyridinium recipitation from the nondialyzable portion of the degradation products of egg-white lysozyme was studied by the periodate oxidation and methylation procedures [2].
• Using a modified papain digestion cetylpyridinium salt precipitation method, glycosaminoglycans were isolated from 21 mesotheliomas, 34 primary lung carcinomas, 12 carcinomas of other sites, and 7 soft tissue sarcomas [3].

High impact information on CETYLPYRIDINIUM

• Visualization of glycosaminoglycans in rat incisor predentin and dentin with cetylpyridinium chloride-glutaraldehyde as fixative [4].
• The membrane conductance increased up to ten times when negatively charged phosphatidyl glycerol was used, while the conductance decreased in positively charged cetylpyridinium containing membranes at pH 4 [5].
• The extensive interaction of the cetylpyridinium ion with gelatin may result in reduced bioavailability [6].
• Repeatability in migration times (R.S.D.%) for benzethonium and cetylpyridinium ions were 0 [7].
• Quenching of fluorescence of 1-hydroxypyrene-3,6,8-trisulfonate (HPTS) by Cu2+, Co2+, Ni2+, I-, and cetylpyridinium (CP+) ions in water/AOT/heptane microemulsion [8].

Anatomical context of CETYLPYRIDINIUM

• Cellular responses to pentobarbital were microvilli formation, reduction in cetylpyridinium chloride-stainable surface coat and epithelial dissociation with thinning of the basement membrane [9].
• Corneas were fixed for electron microscopy in fixative containing 0.5% cetylpyridinium chloride (CPC) to stabilize the layer of mucin-like glycoprotein on the corneal surface [10].
• Demonstration of mast cell granules by the cetylpyridinium chloride-acid dye (CPC-AD) and cetylpyridinium chloride-phosphotungstic acid (CPC-PTA) methods [11].
• Proteohyaluronic acid was extracted from human umbilical cord with 0.2% NaCl, then purified by cetylpyridinium chloride(CPC)-precipitation, DEAE-cellulose column chromatography, gel-filtration on Sephadex G-200 and on Sepharose 4B, in succession [12].
• Addition of monensin to preparations of large unilamellar vesicles prepared from egg-yolk phosphatidylcholine (egg PC) or egg PC containing 5% phosphatidylserine (PS-) or cetylpyridinium (CP+) ions in lithium chloride solution allows the transport of Li+ ions to be monitored by an NMR magnetisation transfer technique [13].

Associations of CETYLPYRIDINIUM with other chemical compounds

• The electrode, which is based on ion-associate compounds formed between cetylpyridinium and chlorothallate(III) complexes dissolved in tricresyl phosphate as pasting liquid, showed near-Nernstian response over the concentration range of 5.8 x 10(-6) - 2.9 x 10(-3) mol/L [14].
• A new antitumor polysaccharide, TC-13, was prepared from the hot-water extract of Microellobosporia grisea by precipitation with cetylpyridinium chlorideborate complex and gel filtration [15].

Gene context of CETYLPYRIDINIUM

• A cetylpyridinium chloride-phosphotungstic acid procedure suggested by Kelényi and Kiss (1976) for the staining of mast cell granules in ultrathin sections was slightly modified with regard to pretreatment, pH of incubation, and rinsing of sections [16].

Analytical, diagnostic and therapeutic context of CETYLPYRIDINIUM

• To measure the amount of the acidic EPS amylovoran synthesized by E. amylovora cell cultures, a turbidity assay using cetylpyridinium salt was developed [17].
• Over a 72-h experimental non-brushing period, during which subjects abstained from all forms of mechanical oral hygiene, one group (test) used a 15 ml alcohol free 0.12% CHX (=18 mg) mouthrinse on a Cpc base (Perioaid), CHX plus sign in circleCpc), twice daily for 30 s [18].
• Cetylpyridinium tetrachlorozincate is recommended as a standard for tenside titration [19].
