| 영문 | uric acid | 한글 | 요산 |
|---|---|---|---|
| 설명 | 결정성의 산. 2, 6, 8-trioxypurine. 화학식은 C5H4N4O3로 사람과 동물의 오줌에서 얻을 수 있다. 핵의 대사산물의 하나. 물, 알콜, 에테르(ether)에는 거의 녹지 않으나 알칼리염의 용액에는 녹는다. 이것의 나트륨염 형태(sodium urate)가 결석의 대부분을 차지한다. 급성백혈병 치료 초기단계와 통풍(Gout)에서 혈중요산이 급격히 오를 수 있다. |

| 영문 | acid-fast bacillus | 한글 | 항산막대균, 항산균 |
|---|---|---|---|

| 영문 | acid-fast staining | 한글 | 항산염색 |
|---|---|---|---|
| 설명 | 항산성성질(좀처럼 염색이 되지 않으나 한번 염색이 되면 산성용액에 의해서 탈색이 되지 않는 성질)을 가진 균(예를 들면 결핵균 등)의 검출에 이용되는 염색방법. 방법에는 Ziehl-Neelson법과 Kinyoun법 등이 있다. |

| 영문 | nucleic acid | 한글 | 핵산 |
|---|---|---|---|
| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
|---|---|
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| ACTH stimulation test | A test for adrenal cortical function; ACTH administered by continuous intravenous infusion, or intramuscularly, evokes an increase in plasma cortisol in normal persons; in adrenal cortical insufficiency, the expected increase in plasma cortisol is limited or nonexistent. (05 Mar 2000) |
| ACTH suppression test | <investigation> A test that measures the response of the adrenal glands to ACTH. In this case, dexamethasone is given to the patient and then blood cortisol levels are measured. Under normal conditions, cortisol levels should drop in response to dexamethasone. In this test one milligram of dexamethasone is administered in the morning and then the blood is drawn for analysis the following morning. Abnormal test results can indicate Cushing's syndrome. (27 Sep 1997) |
| adhesion test | The diagnostic application of the immune adhesion phenomenon. Synonym: erythrocyte adherence test, immune adhesion test, red cell adherence test. (05 Mar 2000) |
| Adler's test | A test for blood; the suspected fluid is treated with glacial acetic acid and ether, and the latter is then decanted and treated with hydrogen peroxide and a solution of benzidine in acetic acid; the presence of blood is indicated by a bluish colour turning to purple. Synonym: Adler's test. (05 Mar 2000) |
| Adson's test | A test for thoracic outlet syndrome; the patient is seated, with head extended and turned to the side of the lesion; with deep inspiration there is a diminution or total loss of radial pulse on the affected side. Not all patients with a positive Adson's test have thoracic outlet syndrome. Synonym: Adson manoeuvre. (05 Mar 2000) |
| agglutination test | <investigation> A serologic test to demonstrate the presence of antibodies in the blood. It is dependent on the clumping of cells, microorganisms, or particles when mixed with specific antiserum. See: agglutination. (04 Jul 1999) |
| AIDS test | <investigation> A test which is performed on a standard venipuncture blood specimen which detects the presence of antibodies to HIV (virus). This test may not be positive for 3 to 6 months after infection with HIV. (27 Sep 1997) |
| Albarran's test | A test for renal insufficiency wherein the drinking of large quantities of water will cause a proportionate increase in the volume of urine if the kidneys are sound, but not if the epithelium of the secreting tubules is damaged. Synonym: polyuria test. (05 Mar 2000) |
| alkali denaturation test | A test for haemoglobin F (Hb F), based on the fact that haemoglobins, with the exception of Hb F, are denatured by alkali to alkaline haematin; the test is sensitive to 2% or more Hb F. (05 Mar 2000) |
| Allen-Doisy test | A test for oestrogenic activity; the material to be investigated is injected repeatedly into immature or spayed rats or mice; the disappearance of leukocytes from the vaginal smear and the appearance of cornified cells constitutes a positive reaction. (05 Mar 2000) |
| Allen's test | For phenol: upon the addition of 5 or 6 drops of hydrochloric acid and then 1 of nitric acid to the suspected fluid, a red colour develops. For strychnine: fluid is extracted with ether, which is then evaporated by means of "drop-by-drop" pipetting into a warmed porcelain dish or crucible; the residue is treated with a small bit of manganese dioxide and dilute sulfuric acid; a red-blue or violet colour develops if strychnine is present. Origin: A.H. Allen A test for radial or ulnar patency; either the radial or ulnar artery is digitally compressed by the examiner after blood has been forced out of the hand by clenching it into a fist; failure of the blood to diffuse into the hand when opened indicates that the artery not compressed is occluded. Origin: Edgar Van Nuys Allen (05 Mar 2000) |
| allergy skin test | Test done on the skin to identify the allergy substance (allergen) triggering the allergic reaction. A small amount of the suspected allergy substance is placed on the skin. The skin is then gently scratched through the small drop with a special sterile needle. If the skin reddens and, more importantly, swells, then allergy to that substance is probable. (12 Dec 1998) |
| Almen's test for blood | Glacial acetic acid, gum guaiac solution, and hydrogen peroxide are added to an aqueous suspension of the suspected stain; if occult blood or blood pigment is present, a blue colour develops. Synonym: guaiac test, Schonbein's test, van Deen's test. (05 Mar 2000) |
