|---|---|---|---|
| 설명 | 적혈구세포의 삼투압 특성 변화에 대한 민감성. 적혈구가 저농도의 나트륨 용액에 노출하면 세포막의 능력을 초과할 때까지 다량의 물을 흡수하여 부풀어올라 파열하고 고농도의 나트륨 용액에 노출하면 적혈구의 세포내액이 빠져나가 크기가 줄어들며 파괴된다. 예외적 취약성이나 저항성은 특정 병의 진단적 기준이 될수 있다. 정상세포는 0.39~0.45% 소금물 용액에서 용혈이 시작되며, 37℃(98.6℉)에서 0.30~0.33% 소금 용액에 적혈구를 노출시키면 용혈은 24시간 이내에 완료된다. |

| 설명 | 혈액이 응고되는 것을 방지하는 항응고제를 넣은 혈액을 침강용 유리관에 넣어 가만히 세워 두었을 때 적혈구가 가라앉는 속도를 이르는 말이다. 1918년 스웨덴의 병리학자 파레우스의 창안에 의한 것이다. 측정방법으로 여러 가지가 있는데, 국제표준법으로는 1973년 웨스터그렌법의 1시간법이 선정되었으며, 1977년 그것을 개정하여 각국에서 쓰도록 권장하고 있다. 1시간 후 침강용 유리관 위쪽의 혈장기둥의 높이를 mm로 읽어, 그것을 적혈구침강의 1시간값으로 한다. 만약 혈장과 적혈구의 경계가 선명하지 못한 경우, 적혈구의 밀도가 그 이하에서는 일정하다고 여겨지는 곳의 눈금을 읽어 적혈구침강의 1시간값으로 한다. 측정 때의 실내온도는 18~25도로 한다. 일반적으로 이보다 온도가 높은 경우는 혈침반응이 촉진되며, 낮은 경우는 늦어진다. 정상 값은 2~10mm(남자), 3~15mm(여자)이며 15세 이하의 어린이, 50세 이상의 고령자에서는 약간 높다. |

| capillary fragility | The lack of resistance, or susceptibility, of capillaries to damage or disruption under conditions of increased stress. (12 Dec 1998) |
|---|---|
| capillary fragility test | A tourniquet test used to determine presence of vitamin C deficiency or thrombocytopenia; a circle 2.5 cm in diameter, the upper edge of which is 4 cm below the crease of the elbow, is drawn on the inner aspect of the forearm, pressure midway between the systolic and diastolic blood pressure is applied above the elbow for 15 minutes, and a count of petechiae within the circle is made: 10, normal; 10 to 20, marginal zone; over 20, abnormal. See: Rumpel-Leede test. Synonym: capillary resistance test, vitamin C test. (05 Mar 2000) |
| osmotic fragility | The susceptibility, or lack of resistance, of erythrocytes to haemolysis when exposed to increasingly hypotonic saline solutions. (12 Dec 1998) |
| fragility | Brittleness; liability to break, burst, or disintegrate. Synonym: fragilitas. Origin: L. Fragilitas (05 Mar 2000) |
| fragility of the blood | The susceptibility, or lack of resistance, of erythrocytes to haemolysis when exposed to increasingly hypotonic saline solutions. (12 Dec 1998) |
| fragility test | A test that measures the resistance of erythrocytes to haemolysis in hypotonic saline solutions; erythrocytes to be tested are added to varying concentrations of saline (usually ranging from 0.85 to 0.10% sodium chloride with 0.05% increments), and beginning and complete haemolysis are measured; normal erythrocytes show initial haemolysis at concentrations of 0.45 to 0.39% and complete haemolysis at 0.33 to 0.30%; in hereditary spherocytosis the fragility of the erythrocytes is markedly increased, whereas in thalassaemia, sickle cell anaemia, and obstructive jaundice the fragility of the erythrocytes is usually reduced. Synonym: erythrocyte fragility test. (05 Mar 2000) |
| rate, erythrocyte sedimentation | A sedimentation rate, or sed rate , is a blood test that detects and is used to monitor inflammation activity. It is measured by recording the rate at which red blood cells (rbcs) sediment in a tube over time. It increases (the rbcs sediment faster) with more inflammation. (12 Dec 1998) |
| erythrocyte | A red blood cell. (18 Nov 1997) |
| erythrocyte adherence phenomenon | A phenomenon manifested by the adherence of antigen-antibody-complement complex to "indicator cells" (microorganisms, platelets, leukocytes, or erythrocytes), the reaction being sensitive and specific for the antigen and antibody in the complex. Synonym: erythrocyte adherence phenomenon, immune adherence phenomenon, red cell adherence phenomenon. (05 Mar 2000) |
| erythrocyte aggregation | Aggregation of erythrocytes probably resulting from changes in the negative surface charge (zeta potential) of the cells caused by the dielectric effect of proteins in the surrounding plasma, especially asymmetric macromolecules like fibrinogen and gamma-globulin. (12 Dec 1998) |
| erythrocyte aggregation, intravascular | The massing or clumping of erythrocytes in intact blood vessels in response to injury or in certain diseases, interfering with adequate blood flow. It is also called sludging of blood and intravascular agglutination. (12 Dec 1998) |
| erythrocyte aging | Senescence of the red blood cell. Lacking the organelles that make protein synthesis possible, the mature erythrocyte is incapable of self-repair, reproduction, and carrying out certain functions performed by other cells. This limits the average life span of an erythrocyte to 120 days. (12 Dec 1998) |
| erythrocyte count | A count of the number of red blood cells per unit volume in a sample of venous blood. (12 Dec 1998) |
| erythrocyte deformability | Ability of erythrocytes to change shape as they pass through narrow spaces, such as the microvasculature. (12 Dec 1998) |
| erythrocyte ghost | <cell biology> The membrane and cytoskeletal elements of the erythrocyte devoid of cytoplasmic contents, but preserving the original morphology. (18 Nov 1997) |
| erythrocyte fragility |
the susceptibility, or lack of resistance, of erythrocytes to hemolysis under certain circumstances; see mechanical f. and osmotic f.
