| porcelain | <botany> Purslain. A fine translucent or semitransculent kind of earthenware, made first in China and Japan, but now also in Europe and America; called also China, or China ware. "Porcelain, by being pure, is apt to break." (Dryden) Ivory porcelain, porcelain with a surface like ivory, produced by depolishing. See Depolishing. Porcelain clay. See Clay. <zoology> Porcelain crab, a cowry. Origin: F. Porcelaine, It. Porcellana, orig, the porcelain shell, or Venus shell (Cypraea porcellana), from a dim. Fr. L. Porcus pig, probably from the resemblance of the shell in shape to a pig's back. Porcelain was called after this shell, either on account of its smoothness and whiteness, or because it was believed to be made from it. See Pork. Source: Websters Dictionary (01 Mar 1998) |
| porcelain gallbladder | <radiology> Calcium incrustation of gallbladder wall, 0.6-0.8% of cholecystectomy patients, 80% female, 10-20% develop gallbladder carcinoma, 90% associated with gallstones findings: nonfunctioning gallbladder on oral cholecystogram, highly echogenic shadowing curvilinear sturucture in the gallbladder fossa (Differential diagnosis: stone-filled contracted gall bladder), echogenic gallbladder wall with little acoustic shadowing (Differential diagnosis: emphysematous cholecystitis), scattered irregular clumps of echoes with posterior acoustic shadowing (12 Dec 1998) |
| porcelain inlay | A fused porcelain restoration luted in a cavity prepared in a tooth. (05 Mar 2000) |
| dental porcelain | <chemical> A type of porcelain used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Dental porcelain is produced by mixing ceramic powder (a mixture of quartz, kaolin, pigments, opacifiers, a suitable flux, and other substances) with distilled water. Chemical name: Dental materials and fillings, porcelain (12 Dec 1998) |
| back pain, low | Symptoms in the low back can relate to the bony lumbar spine, discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, muscles of the low back, internal organs of the pelvis and abdomen, and the skin covering the lumbar area. The low back, or lumbar area, functions in structural support, movement, and protection of certain body tissue. (12 Dec 1998) |
| blood sugar, low | The sugar here is glucose. Low blood glucose constitutes hypoglycaemia. Hypoglycaemia is only significant when it is associated with symptoms. It has many causes including drugs, liver disease, surgical absence of the stomach, pre-diabetes, and rare tumours that release excess insulin. (12 Dec 1998) |
| cardiac output, low | A state of subnormal or depressed cardiac output, usually seen in patients with heart failure secondary to coronary artery, hypertensive, primary myocardial, valvular, or pericardial disease. (12 Dec 1998) |
| very low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats (particularly triglycerides) in the bloodstream. Elevations in very low density lipoprotein in the bloodstream are associated with an increased risk of atherosclerosis and coronary artery disease. Acronym: VLDL (18 Nov 1997) |
| Castellani-Low sign | <clinical sign> A fine tremor of the tongue observed in sleeping sickness. (05 Mar 2000) |
| mean lower low water | <marine biology> The average height of the lower low waters over a 19-year period. For shorter periods of observations, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. (09 Oct 1997) |
| mean low water | <marine biology> The average height of the low waters over a 19-year period. For shorter periods of observations, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. All low-water heights are included in the average where the type of tide is either semidiurnal or mixed. Only the lower low-water heights are included in the average where the type of tide is diurnal. So determined, mean low water in the latter case is the same as mean lower low water. (09 Oct 1997) |
| placenta, low | Location of the placenta in the lower part of the uterus (womb) so that the placenta partially or completely covers the cervix. Also known as a placenta previa. (12 Dec 1998) |
| heparin, low-molecular-weight | <chemical> Heparin fractions with a molecular weight usually between 4000 and 6000 kD. These low-molecular-weight fractions are effective antithrombotic agents. Their administration reduces the risk of haemorrhage, they have a longer half-life, and their platelet interactions are reduced in comparison to unfractionated heparin. They also provide an effective prophylaxis against postoperative major pulmonary embolism. Pharmacological action: anticoagulant, fibrinolytic agent. (12 Dec 1998) |
| infant, low birth weight | An infant having a birth weight of 2500 gm. (5.5 lb.) or less but infant, very low birth weight is available for infants having a birth weight of 1500 grams (3.3 lb.) or less. (12 Dec 1998) |
