| lipid storage diseases | A series of disorders due to inborn errors in lipid metabolism resulting in the abnormal accumulation of lipids in the wrong places (examples include gaucher, fabry and niemann-pick diseases and metachromatic leukodystrophy). (12 Dec 1998) |
| liver diseases, alcoholic | Liver diseases associated with alcoholism. It usually refers to the coexistence of two or more subentities, i.e., alcoholic fatty liver, alcoholic hepatitis, and alcoholic liver cirrhosis, but may be the general entity when subentities are not specified.

See: the following conditions: Hurler sundrome, Hunter syndrome, San Fillipo, Gaucher's disease, Niemann-Pick, Pompe's disease, Tay Sachs disease. (18 Nov 1997) |

| absolute system of units | A system based on absolute units accepted as being fundamental (length, mass, time) and from which other units (force, energy or work, power) are derived; such system's in common use are the foot-pound-second, centimeter-gram-second, and meter-kilogram-second system's.
