| 설명 | 사람의 몸에 상처가 나서 출혈이 있을 경우에 이것을 막고 피를 더이상 나지 않게 하는 것을 지혈이라고 한다. 지혈의 과정에는 크게 두 가지 단계가 있다. 첫번째 단계는 혈소판들이 상처가 나서 손상된 혈관의 부위를 막는 것이다. 이렇게 하면 우선 혈관의 손상부위로 부터 피가 나오는 것을 막을 수가 있다. 다음의 단계는 상처를 막고 있는 혈소판위에 여러 가지 물질들이 작용해서 더욱 단단하게 하여 상처가 난 혈관에서 피가 새는 것을 영구히 막는 것이다. 쉽게 말하면 혈소판은 벽돌에 해당하는 것이고 두번째 과정에 참여하는 물질들은 시멘트에 해당하는 것이다. 이 두 과정이 완전할 경우에 지혈이 순조롭게 일어난다. 혈액응고란 두번째 단계를 지칭하는 말로써 매우 복잡한 단계를 거치는 반응으로 마지막 단계는 섬유소라는 물질이 만들어져서 이 물질이 혈소판과 그 외의 세포를 단단하게 고정시켜 피가 상처난 혈관으로 새는 것을 막는다. 이것을 가장 간단히 설명하자면 크게 다음과 같은 3가지 단계로 이루어진다. 첫번째 단계는 혈관손상에 의해서 프로트롬빈 활성제라는 것이 만들어지는 단계이다. 두번째 단계는 이 프로트롬빈 활성제라는 물질에 의해서 혈액속에 있는 프로트롬빈이라는 물질이 트롬빈이라는 물질로 바뀌는 단계이다. 세번째 단계는 트롬빈이라는 물질에 의해서 섬유소원이라는 물질이 섬유소으로 바뀌는 단계이다. |

| 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) |
| Russell's viper venom clotting time | A clotting time determination performed on citrated platelet-poor plasma using Russell's viper venom as an activating agent. This allows activation of factor X directly without the need for other coagulation factors and is used to confirm factor X defects. See: Stypven time test. (05 Mar 2000) |
| clotting factor | <haematology> A group of chemical constituents of the blood (factors I to XIII) which interact to make the blood clot. (13 Nov 1997) |
| clotting time | The time required for blood to coagulate; prolonged in haemophilia and in the presence of obstructive jaundice, some anaemias and leukaemias, and some of the infectious diseases. Synonym: clotting time. (05 Mar 2000) |
| association mechanism | The cerebral mechanism whereby the memory of past sensations may be compared or associated with present ones. (05 Mar 2000) |
| biochemical mechanism | This is the general term for any chemical reaction or series of reactions, usually mediated by enzymes, which produce a given physiological effect in a living organism. (09 Oct 1997) |
| Cairns mechanism | <molecular biology> A mechanism for the replication of a double stranded circular DNA molecule. Replication is initiated at a fixed point and proceeds either uni or bi directionally. (18 Nov 1997) |
| gating mechanism | Occurrence of the maximum refractory period among cardiac conducting cells approximately 2 mm proximal to the terminal Purkinje fibres in the ventricular muscle, beyond which the refractory period is shortened through a sequence of Purkinje cells, transitional cells, and muscular cells; gating mechanism may be a cause of ventricular aberration, bidirectional tachycardia, and concealed extrasystoles, a mechanism by which painful impulses may be blocked from entering the spinal cord. Compare: gate-control theory. (05 Mar 2000) |
| random mechanism | A scheme for substrate binding and product release for a multisubstrate enzyme; for a two-substrate two-product enzyme with this mechanism, either substrate can bind first and, after the reaction has taken place, either product can be the first to dissociate from the enzyme. Brain hexokinase has a random mechanism. More complex random mechanisms exist for enzymes having more than two substrates. (05 Mar 2000) |
| cassette mechanism | <molecular biology> Term used for genes such as the a and _ genes that determine mating type in yeast, either one or the other is active. In this gene conversion process, a double stranded nuclease makes a cut at a specific point in the MAT locus, the old gene is replaced with a copy of a silent gene from one or other flanking region and the new copy becomes active. As the process involves replacing one ready made construct with another in an active slot it is called a cassette mechanism. (18 Nov 1997) |
| re-entrant mechanism | The probable basis of most arrhythmias, requiring at least three criteria in the heart: 1. A loop circuit, 2. Unidirectional block, 3. Slowed conduction. Impulses enter the loop circuit and divide in both directions (blocked in one direction only), negotiate the loop circuit to the area of block where the slowed conduction has allowed the impulse to arrive at a time when the tissue proximal to the unidirectional block has recovered and will permit its passage in the opposite direction. (05 Mar 2000) |
| mechanism | The manner of combination of parts, processes, etc., which subserve a common function. Origin: Gr. Mechan = machine (18 Nov 1997) |
| mechanism-based inhibitor | A competitive inhibitor that is converted to an irreversible inhibitor at the active site of the enzyme. Synonym: mechanism-based inhibitor. (05 Mar 2000) |
| rolling circle mechanism | <molecular biology> A mechanism of DNA replication in many viral DNAs, in bacterial f factors during mating and of certain DNAs in gene amplification in eukaryotes. DNA synthesis starts with a cut in the + strand at the replication origin, the 5' end rolls out and replication starts at the 3' side of the cut around the intact circular DNA strand. Replication of the 5' end (tail) takes place by the formation of Okazaki fragments. (18 Nov 1997) |
