| 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) |

| heparin lyase | <enzyme> An enzyme of the isomerase class that catalyses the eliminative cleavage of polysaccharides containing 1,4-linked d-glucuronate or l-iduronate residues and 1,4-alpha-linked 2-sulfoamino-2-deoxy-6-sulfo-d-glucose residues to give oligosaccharides with terminal 4-deoxy-alpha-d-gluc-4-enuronosyl groups at their non-reducing ends. Chemical name: heparin lyase Registry number: EC 4.2.2.7 (12 Dec 1998) |
| heparin unit | The quantity of heparin required to keep 1 ml of cat's blood fluid for 24 hr at 0캜; it is equivalent approximately to 0.002 mg of pure heparin. Synonym: Howell unit. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| alpha units | Cytoplasmic glycogen granules arranged in rosettes. (05 Mar 2000) |
| base units | The fundamental unit's of length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity in the International System of Units (SI); the names and symbols of the unit's for these quantities are meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd). See: International System of Units. (05 Mar 2000) |
| burn units | Specialised hospital facilities which provide intensive care for burn patients. (12 Dec 1998) |
| gravitational units | Of energy: gram-centimeter, gram-meter, kilogram-meter, and foot-pound. (05 Mar 2000) |
| mobile health units | Movable facilities in which diagnostic and therapeutic services are provided to the community. (12 Dec 1998) |
| colony-forming units assay | A cytologic technique for measuring the functional capacity of stem cells by assaying their activity. (12 Dec 1998) |
| Wood units | A simplified measurement of pulmonary vascular resistance that uses pressures instead of more complicated units measured by subtracting pulmonary capillary wedge pressure from the mean pulmonary arterial pressure and dividing by cardiac output in liters per minute. (05 Mar 2000) |
| coronary care units | The hospital unit in which patients with acute cardiac disorders receive intensive care. (12 Dec 1998) |
| haemodialysis units, hospital | Hospital units in which care is provided the haemodialysis patient. This includes haemodialysis centres in hospitals. (12 Dec 1998) |
| practical units | Unit's of magnitudes convenient for use in the practical applications of electricity; as originally defined they were absolute unit's (multiples of CGS electromagnetic unit's); they include the ampere, coulomb, farad, henry, joule, ohm, volt, and watt. (05 Mar 2000) |
| self-care units | Rooms in health care facilities for patients who require a minimal level of care. (12 Dec 1998) |
