| 영문 | whole blood | 한글 | 전혈, 온혈액 |
|---|---|---|---|
| 설명 | 혈액의 모든 성분이 하나도 제거되지 않은 온전한 혈액. 전혈은 엄격한 무균조건하에서, 선별한 공혈자로부터 채취한 것이며, 구연산 이온이나 헤파린 같은 항응공제로 응고를 방지하여 혈액보충 목적으로 사용한다. |

| 영문 | blood collection | 한글 | 채혈 |
|---|---|---|---|
| 설명 | 1. 모세관혈 : 혈구수-혈소판수 계산, 혈색소량, 혈구용적측정, 도말표본제작 등을 할때 사용된다. 귓불 또는 손가락끝바닥면을 충분히 마찰한 다음, 알코올로 소독-건조시켜서, 작은 칼 또는 종두침 혹은 1mm의 주사침으로 2~3mm의 깊이까지 찌른다. 맨처음 피방울은 닦아낸 후 다음 핏방울을 검사에 이용한다. 2. 정맥혈 : 대량의 혈액을 요하는 경우에 사용한다. 보통 (팔꿈치정중피부)주정중피정맥을 찌르며, 영유아의 경우에는 외경정맥을 선택하기도 한다. 지혈용 고무줄로 상단을 최저혈압에 상당하는 정도로 묶고, 주먹을 꼭 쥐게 하여 정맥을 노출시킨 후 멸균건조주사기를 혈관내에 삽입한다. 곧 바로 고무줄과 주먹을 풀고 채혈을 한 다음 혈액을 시험관에 넣는다. 2분이상의 정맥 울혈은 혈액성상에 변화를 가져온다. 2. 동맥혈 : 위팔동맥 또는 넙다리 동맥을 사용하여 천자부를 소독한 다음, 프로카인 국소마취를 한다. 채혈자 왼손의 가운데손가락과 둘째손가락으로 동맥을 고정하고, 주사침을 동맥에 45~65℃의 각도로 찔러 넣어 채혈 후 몸쪽동맥을 엄지손가락으로 압박하면서 주사침을 빼고, 그 뒤 5분간쯤 찌른 부위를 압박한다. |

| 영문 | blood-brain barrier(BBB) | 한글 | 혈뇌장벽 |
|---|---|---|---|
| 설명 | 뇌와 척수에는 혈류로부터 어떤 물질이 유입되는 것을 막는 장벽이다. 이것은 뇌와 척수에 존재하는 모세혈관의 투과성이 비교적 다른 모세혈관의 투과성보다 떨어지기 때문이다. |

| 영문 | blood pressure | 한글 | 혈압 |
|---|---|---|---|
| 설명 | 혈압이란 혈관에 걸리는 압력을 말하는 것으로 대개 특별한 설명이 없으면 동맥의 압력을 말한다. 혈압에는 수축기혈압(systolic blood pressure)과 이완기혈압(diastolic blood pressure)이 있다. 수축기혈압이란 심장이 수축할 경우에 동맥에 걸리는 압력을 말하고, 이완기 혈압이란 심장이 이완할 경우에 동맥에 걸리는 압력을 말한다. 당연히 수축기 혈압이 이완기 혈압보다 높다. 혈압을 말할 때에 예를 들어 120/80mmHg이라고 적는 것의 앞의 것은 수축기 혈압을 의미하고 뒤에 적는 80은 이완기 혈압을 의미한다. |

| blood-cerebrospinal fluid barrier | A barrier located at the tight junctions which surround and connect the cuboidal epithelial cells on the surface of the choroid plexus; capillaries and connective tissue stroma of the choroid do not represent a barrier to protein tracers or dyes. (05 Mar 2000) |
|---|---|
| blood circulation | The course of the blood from the heart through the arteries, capillaries, and veins back again to the heart. (05 Mar 2000) |
| blood circulation time | Determination of the shortest time interval between the injection of a substance in the vein and its arrival at some distant site in sufficient concentration to produce a recognizable end result. It represents approximately the inverse of the average velocity of blood flow between two points. (12 Dec 1998) |
| blood clot | <haematology> The conversion of blood from a liquid form to solid through the process of coagulation. A thrombus is a clot which forms inside of a blood vessel. If that clot moves inside the vessel it is referred to as an embolus (embolism). The presence of atherosclerotic plaque lining blood vessel walls is a significant stimulus for clot formation. (27 Sep 1997) |
| blood clotting factor | <haematology> Any of a number of different protein factors which, when acting together, can form a blood clot shortly after platelets have broken at the site of the wound. The factors have Roman numeral names, like VII, VIII, IX, X, XI, and XIII. Defects in the genes which code for any of these factors result in genetic diseases like haemophilia, which results from a defect in the gene for factor VIII or IX. (09 Oct 1997) |
| blood coagulation | The sequential process by which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages: stage 1, the formation of intrinsic and extrinsic prothrombin converting principle; stage 2, the formation of thrombin; stage 3, the formation of stable fibrin polymers. (12 Dec 1998) |
| blood coagulation factor inhibitors | Substances, usually endogenous, that act as inhibitors of blood coagulation. They may affect one or multiple enzymes throughout the process. As a group, they also inhibit enzymes involved in processes other than blood coagulation, such as those from the complement system, fibrinolytic enzyme system, blood cells, and bacteria. (12 Dec 1998) |
| blood coagulation factors | Endogenous substances, usually proteins, that participate in the blood coagulation process. (12 Dec 1998) |
| blood coagulation tests | Laboratory tests for evaluating the individual's clotting mechanism. (12 Dec 1998) |
| 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) |
