| Abs | absorption |
|---|---|
| absorp | absorption |
| AC | abdominal circumference; abdominal compression; absorption coefficient; abuse case; acetate; acetylc... |
| ADME | [drug] absorption, distribution, metabolism, and excretion |
| AET | absorption-equivalent thickness;S-(2-aminoethyl) isothiuronium |
| percutaneous absorption | The absorption of drugs, allergens, and other substances through unbroken skin. Synonym: cutaneous absorption. (05 Mar 2000) |
|---|---|
| circle absorption anaesthesia | Inhalation anaesthesia in which a circuit with carbon dioxide absorbent is used for complete (closed) or partial (saemiclosed) rebreathing of exhaled gases. (05 Mar 2000) |
| photoelectric absorption | <chemistry, physics> The interaction of an X-ray photon with matter in which the incident photon is completely absorbed, giving up all its energy by displacing an outer shell electron. (05 Mar 2000) |
| molar absorption coefficient | Absorbance (of light) per unit path length (usually the centimeter) and per unit of concentration (moles per liter); a fundamental unit in spectrophotometry. Synonym: absorbancy index, absorptivity, molar absorbancy index, molar absorptivity, molar extinction coefficient. (05 Mar 2000) |
| cutaneous absorption | The absorption of drugs, allergens, and other substances through unbroken skin. Synonym: cutaneous absorption. (05 Mar 2000) |
| specific absorption coefficient | Absorbance (of light) per unit path length (usually the centimeter) and per unit of mass concentration. Compare: molar absorption coefficient. Synonym: absorbancy index, absorptivity, extinction coefficient, specific extinction. (05 Mar 2000) |
| spectrophotometry, atomic absorption | A highly sensitive technique used to analyze various elements, especially metals, including aluminum, arsenic, beryllium, calcium, copper, iron, lead, and lithium, which are present in trace amounts. The atoms are excited above a ground state by flame vaporization, and the radiation emitted as the molecules return to a ground state is measured in unexcited non-ionised molecules. (12 Dec 1998) |
| disjunctive absorption | Absorption of living tissue in immediate relation with a necrosed part, producing a line of demarcation. (05 Mar 2000) |
| d-xylose absorption | This test measures the intestine's ability to absorb the simple sugar, D-xylose. This is an indicator for whether or not nutrients are being absorbed properly in the intestine. This test is often used to evaluate persistent diarrhoea, weight loss, malnutrition and cases of suspected malabsorption. Abnormal results may be seen in the following conditions: Crohn's disease, Giardiasis, hookworm infestation, radiation enteritis, celiac sprue, viral gastroenteritis and Whipple's disease. (27 Sep 1997) |
| electron resonance absorption | <physics> A spectrometric method, based on measurement of electron spins and magnetic moments, for detecting and estimating free radicals in reactions and in biological systems. Synonym: electron paramagnetic resonance. (05 Mar 2000) |
| external absorption | The absorption of substances through skin, mucocutaneous surfaces, or mucous membranes. (05 Mar 2000) |
| fluorescent treponemal antibody-absorption test | <investigation> A sensitive and specific serologic test for syphilis. It is more specific than the VDRL assay. The patient's serum is diluted to remove non-specific antibodies and then mixed on a glass slide with Nichol's strain of Treponema pallidum. If antibodies are present in the patient's serum they bind to the antigen and the bound antibodies are detected with fluoresceinated antihuman gamma-globulin antibody. Synonym: FTA-ABS test. (12 Sep2002) |
| linear absorption coefficient | That fraction of ionizing radiation absorbed in a unit thickness of a substance or tissue. See: absorption coefficient. (05 Mar 2000) |
| acute interstitial nephritis | <nephrology> A relatively uncommon condition which is characterised by inflammation of the renal tubules, glomeruli and surrounding tissue. Interstitial nephritis is usually be temporary and often associated with the use of a particular medication. Chronic and progressive forms do exist. Drugs that have been associated with interstitial nephritis include penicillins, ampicillin, sulpha drugs, non-steroidal anti-inflammatory agents, furosemide and thiazide diuretics. May result in mild kidney dysfunction or acute renal failure. Treatment may be with corticosteroids. Incidence: 1 in 25,000. (29 Dec 1997) |
| acute interstitial pneumonia | A severe and usually fatal form of pneumonia occurring primarily in infants usually considered a form of hypersensitivity pneumonitis. (05 Mar 2000) |
