| polymyxin | <chemical> Basic polypeptide antibiotic group obtained from bacillus polymyxa. They affect the cell membrane by detergent action and may cause neuromuscular and kidney damage. at least eleven different members of the polymyxin group have been identified, each designated by a letter. Pharmacological action: antibiotics, peptide. (12 Dec 1998) |
|---|---|
| polymyxin acylase | <enzyme> Deacylates polymyxin, colistin and octapeptin antibiotic Registry number: EC 3.5.1.- (26 Jun 1999) |
| polymyxin b | <chemical> A mixture of polymyxins b1 and b2, obtained from bacillus polymyxa strains. They are basic polypeptides of about eight amino acids and have cationic detergent action on cell membranes. Polymyxin b is used for infections with gram-negative organisms, but may be neurotoxic and nephrotoxic. Pharmacological action: antibiotics, peptide. Chemical name: Polymyxin B (12 Dec 1998) |
| polymyxin B sulfate | An antibacterial effective in tularaemia, brucellosis, Pseudomonas infections, and urinary tract infections, but used systemically only for severe infections not responsive to less toxic agents; it is also used locally. Polymyxin B is a mixture of polymyxin B1 and polymyxin B2. (05 Mar 2000) |
| barotrauma, otic | See: Barotitis. (12 Dec 1998) |
| communicating branch of otic ganglion to auriculotemporal nerve | <anatomy, nerve> A branch of the otic ganglion joining the roots of the auriculotemporal nerve to convey postsynaptic parasympathetic fibres to the parotid gland. Synonym: ramus communicans ganglii otici cum nervo auriculotemporali. (05 Mar 2000) |
| communicating branch of otic ganglion to chorda tympani | A small branch of the otic ganglion conveying sensory fibres to the chorda tympani. Synonym: ramus communicans cum chorda tympani. (05 Mar 2000) |
| communicating branch of otic ganglion with medial pterygoid nerve | <anatomy, nerve> Branch of otic ganglion joining the nerve to the medial pterygoid muscle. Synonym: ramus communicans ganglii otici cum nervo pterygoideo mediali. (05 Mar 2000) |
| communicating branch of otic ganglion with meningeal branch of mandibular nerve | <anatomy, nerve> A branch of otic ganglion to the meningeal branch of mandibular nerve conveying postsynaptic parasympathetic fibres which run back to the main stem of the mandibular nerve for distribution to the parotid gland via the auriculotemporal nerve. Synonym: ramus communicans ganglii otici cum ramo meningeo nervi mandibularis. (05 Mar 2000) |
| otic | Relating to the ear. Origin: G. Otikos, fr. Ous, ear (05 Mar 2000) |
| otic abscess | A cerebral abscess usually involving the temporal lobe or cerebellar hemisphere, due to extension of suppuration of the middle ear. Synonym: otogenous abscess. (05 Mar 2000) |
| otic barotrauma | Middle ear problems due to changing atmospheric pressures, as when a plane descends to land. The problems include ear pain, ringing, diminished hearing and, sometimes, dizziness. Alternate terms include aerotitis: aerotitis media, barotitis, barotitis media. (12 Dec 1998) |
| otic capsule | The cartilage capsule surrounding the inner ear mechanism; in elasmobranchs, it remains cartilaginous in the adult; in the embryos of higher vertebrates, it is cartilaginous at first but later becomes bony (at approximately 23 weeks in humans). (05 Mar 2000) |
| otic ganglion | An autonomic ganglion situated below the foramen ovale medial to the mandibular nerve; its postganglionic, parasympathetic fibres are distributed to the parotid gland. Synonym: ganglion oticum, Arnold's ganglion, auricular ganglion, otoganglion. (05 Mar 2000) |
| otic pits | Paired depressions, one on either side of the head of the embryo, marking the location of the future auditory vesicles. Synonym: otic pits. (05 Mar 2000) |
