| labile hypertension | Frequently changing levels of elevated blood pressure. (05 Mar 2000) |
|---|
| plasma labile factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
|---|---|
| heat-labile | Destroyed or altered by heat. (05 Mar 2000) |
| labile | 1. Gliding, moving from point to point over the surface, unstable, fluctuating. 2. <chemistry> Chemically unstable. Origin: L. Labilis = unstable, from labi = to glide (18 Nov 1997) |
| labile affect | The rapid shifts in outward emotional expressions; often associated with organic brain syndromes such as intoxication. (05 Mar 2000) |
| labile current | An electrical current applied to the body by means of electrodes that are constantly shifted about. (05 Mar 2000) |
| labile elements | Tissue cells, as of epithelium, connective tissue, etc., that continue to multiply by mitosis during the life of the individual. (05 Mar 2000) |
| labile factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| labile pulse | Frequent changes in pulse rate. (05 Mar 2000) |
| accelerated hypertension | <cardiology> A severe form of acute hypertension that results in the abrupt rise in the blood pressure (diastolic pressure often over 120 mmHg). If left untreated, malignant hypertension can cause damage to the blood vessels in the eye, kidneys, brain and heart. Complications include stroke, heart attack, blindness and renal failure. Symptoms include headache, blurred vision, nausea, vomiting and lethargy. Neurologic symptoms are also a common finding. Malignant hypertension occurs more commonly in males, African Americans and those with a history for hypertension. (27 Sep 1997) |
| adrenal hypertension | Hypertension due to an adrenal medullary pheochromocytoma or to hyperactivity or functioning tumour of the adrenal cortex. (05 Mar 2000) |
| benign hypertension | Hypertension that runs a relatively long and symptomless course. (05 Mar 2000) |
| borderline hypertension | By consensus, that blood pressure zone between highest acceptable "normal" blood pressure and hypertensive blood pressure. The Framingham Heart Study defines this as pressures between 140 and 160 mm Hg systolic and 90 and 95 mm Hg diastolic. (05 Mar 2000) |
| pale hypertension | Hypertension with pallor of the skin, a severe form with pronounced constriction of peripheral vessels. (05 Mar 2000) |
| malignant hypertension | A severe form of acute hypertension that results in the abrupt rise in the blood pressure (diastolic pressure often over 120 mmHg). If left untreated, malignant hypertension can cause damage to the blood vessels in the eye, kidneys, brain and heart. Complications include stroke, heart attack, blindness and renal failure. Symptoms include headache, blurred vision, nausea, vomiting and lethargy. Neurologic symptoms are also a common finding. Malignant hypertension occurs more commonly in males, African Americans and those with a history for hypertension. (27 Sep 1997) |
| renal hypertension | Hypertension secondary to renal disease. (05 Mar 2000) |
