| 영문 | blood gas | 한글 | 혈액가스, 혈액기체 |
|---|---|---|---|
| 설명 | 혈액 속에 용해되어 있는 산소, 이산화탄소, 질소 따위의 기체. 혈액의 산성-염기성의 정도를 측정할 수 있다. |

| 영문 | blood test | 한글 | 혈액검사 |
|---|---|---|---|
| 설명 | 혈액형이나 질병 유무 따위를 알기 위하여 피를 뽑아 행하는 검사. 몸 전체의 장기나 조직에 병터가 있으면 이들 성분에 변화가 있게 되어 진단에 큰 도움을 준다. |

| 영문 | blood-brain barrier | 한글 | 혈액뇌장벽 |
|---|---|---|---|
| 설명 | 혈액으로부터 뇌로는 지질용해성이 높은 약물밖에 이행되지 않는다. 수용성의 약물을 뇌로 이행되지 않게 하고 있는 것이 혈액뇌장벽이며 뇌의 모세혈관 내피세포, 모세혈관 주위의 세포가 장벽이 되고 있다. 물질교환은 수동확산에 의해 이루어지지만, 뇌의 생리적 활동에 필요한 물질은 이온형이라도 담체를 통해 이행된다. |

| 영문 | blood volume | 한글 | 혈액량 |
|---|---|---|---|
| 설명 | 체내에 존재하는 혈액의 총량으로서, 보통 리터 또는 체중 1kg에 대하여 리터수로 표시한다. |
||
| 영문 | blood urea nitrogen | 한글 | 혈액요소질소 |
|---|---|---|---|
| 설명 | 요소는 아미노산의 탈아미노에 의해 생긴 암노니아와 탄산가스로부터 간에서 합성된다. 혈중에서는 혈장과 혈구의 물성분 안에 함유되어 있다. 혈액요소질소는 콩팥토리에서 여과되며 일부 요세관에서 재흡수되고, 나머지가 오줌중에 배설된다. 따라서 혈액요소질소는 콩팥기능의 저하에 따라 증가되지만, 식사단백질 섭취량, 조직붕괴, 위장관 출혈 등과 탈수 등 순환혈액량의 이상으로 변동된다. |

|---|---|
| blood component removal | Any procedure in which blood is withdrawn from a donor, a portion is separated and retained and the remainder is returned to the donor. (12 Dec 1998) |
| blood component transfusion | The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in plasmapheresis and types of cytapheresis (plateletpheresis and leukapheresis) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor. (12 Dec 1998) |
| blood corpuscle | <haematology> There are three main types of cell in the blood stream. The red cell, which carries oxygen, the white cell, which fights infections and the platelet, which helps prevent bleeding. The correct balance between each cell type must be maintained for the body to remain healthy. (13 Nov 1997) |
| blood count | <haematology, investigation> The determination of the proper number of red blood cells, white blood cells and platelets are present in the patients blood. Acronym: FBC (16 Dec 1997) |
| blood crisis | The appearance of a large number of nucleated red blood cells in the peripheral blood, accompanied by reticulocytosis and occurring in "exhausted" bone marrow in pernicious anaemia and in haemolytic icterus, a suddenly appearing leukocytosis, indicating a change for the better in the course of a grave blood disease. (05 Mar 2000) |
| blood crystals | <haematology> A substance which appears to be identical to the red-orange bile pigment bilirubin, but which is produced from haemoglobin in tissues rather than within the liver and usually when oxygen tension is low. (09 Oct 1997) |
| blood culture | <investigation, microbiology> A test which involves the incubation of a blood specimen overnight to determine if bacteria are present. (27 Sep 1997) |
| blood disk | <haematology> A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels. Platelet _ granules contain lysosomal enzymes, dense granules contain ADP (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation. Synonym: thrombocytes. (09 Oct 1997) |
| blood dust | Small refractive particles in the circulating blood, probably lipid material associated with fragmented stroma from red blood cells. Synonym: blood dust, blood motes, dust corpuscles. Origin: haemo-+ G. Konis, dust (05 Mar 2000) |
| blood dyscrasia | <haematology> A general term which is used to describe any abnormality in the blood or bone marrow's cellular components, such as low white blood cell count, low red blood cell count or low platelet count. Medications known to cause thrombocytopenia or leukopenia as a side effect include: pyrimethamine, chloramphenicol, levamisole, sulphamethoxazole and trimethoprim, sulphapyridine, sulphasalazine, antihistamines, appetite suppressants, anticonvulsants, tricyclic antidepressants, decongestants and antihistamines, benzodiazepines, chloroquine, clozapine, dapsone, glutethimide, hydroxychloroquine, isoniazid, meprobamate and aspirin, methazolamide, perphenazine and amitriptyline, phenacemide, pimozide, rifampin, thioxanthenes, trimethobenzamide, trimethoprim and trimetaphan. (27 Sep 1997) |
| blood flow velocity | A value equal to the total volume flow divided by the cross-sectional area of the vascular bed. (12 Dec 1998) |
| blood gas analysis | <investigation> A test which analyses arterial blood for oxygen, carbon dioxide and bicarbonate content in addition to blood pH. Used to test the effectiveness of respiration. (27 Sep 1997) |
| blood gases | A clinical expression for the determination of the partial pressures of oxygen and carbon dioxide in blood. (05 Mar 2000) |
| blood gas monitoring, transcutaneous | The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced haemoglobin. (12 Dec 1998) |
