| Greenfield filter | A multistrutted spring-styled filter usually placed in the inferior vena cava to prevent venous emboli from reaching the pulmonary circulation from the lower extremity. (05 Mar 2000) |

| micropore filter | A filter made of a meshwork of cellulose acetate or nitrate and with defined pore size. They can be autoclaved and the smaller pore sizes (0.22m,0.45m) are used for sterilising heat labile materials by filtering out micro organisms. Larger pore size filters are used in setting up Boyden chambers. They are about 150m thick and should be distinguished from Nucleopore filters. Millipore is a trade name for micropore filters. (18 Nov 1997) |
| Millipore filter | <cell culture, equipment> Trade name for a well known brand of micropore filters. (12 Jan 1998) |
| closed anaesthesia | Inhalation anaesthesia in which there is total rebreathing of all exhaled gases, except carbon dioxide which is absorbed; gas flow into the anaesthetic circuit consists only of oxygen, in amounts equal to the patient's metabolic consumption, plus small amounts of other gases (e.g., nitrous oxide) which undergo continued uptake by and distribution in the patient. (05 Mar 2000) |
| closed-angle glaucoma | angle-closure glaucoma |
| closed bite | <dentistry> A malocclusion where your upper teeth cover your lower teeth when you bite down. This is also called a deep bite. (08 Jan 1998) |
| closed chain compound | Any compound in which the constituent atoms, or any part of them, form a ring. Used mainly in organic chemistry where: 1) numerous compound's contain rings of carbon atoms (carbocyclic compound's) or carbon atoms plus one or more atoms of other types (heterocyclic compound's), usually nitrogen, oxygen, or sulfur; 2) where the atoms in the ring are all of the same element (homocyclic or isocyclic compound); 3) where the ring is saturated or contains nonconjugated double bonds (alicyclic compound), the compound is similar in properties to the corresponding acyclic compound (e.g., cyclohexane resembles hexane); 4) where the ring contains conjugated double bonds in a closed loop in which there are 4n + 2 (where n is an integer) delocalised π electrons (Huckel's rule) (aromatic compound; e.g., benzene, pyridine), it is more stable than the corresponding saturated ring and exhibits unusual chemical properties characteristic of itself and not of other types of rings or of acyclic compound's. These aromatic compounds have the ability to sustain an induced ring current. Synonym: closed chain compound, ring compound. (05 Mar 2000) |
| closed chest massage | Rhythmic compression of the heart between sternum and spine by depressing the lower sternum backward with the heels of the hands, the patient lying supine. Synonym: external cardiac massage. (05 Mar 2000) |
| closed circle | A circuit for administration of an inhalation anaesthetic in which there is complete rebreathing with carbon dioxide absorption. (05 Mar 2000) |
| closed circuit method | A method for measuring oxygen consumption in which the subject rebreathes an initial quantity of oxygen through a carbon dioxide absorber and the decrease in the volume of oxygen being rebreathed is noted. (05 Mar 2000) |
| closed comedo | A comedo with a narrow or obstructed opening on the skin surface; closed comedo's may rupture, producing a low-grade dermal inflammatory reaction. Synonym: whitehead. (05 Mar 2000) |
| closed dislocation | A dislocation not complicated by an external wound. Synonym: simple dislocation. (05 Mar 2000) |
| closed drainage | Drainage of a body cavity via a water-or air-tight system. (05 Mar 2000) |
| closed fracture | A fracture in which skin is intact at site of fracture. Synonym: simple fracture. (05 Mar 2000) |
| closed head injury | A head injury in which continuity of the scalp and mucous membranes is maintained. (05 Mar 2000) |
