| 영문 | feedback | 한글 | 되먹임 |
|---|---|---|---|
| 설명 | 입력과 출력을 갖춘 제어시스템에서 출력의 일부를 입력측으로 되돌려 입력으로 사용하는 일. 증폭기나 자동 제어 따위의 전기회로에 많이 사용한다. |

| 영문 | serum enzyme | 한글 | 혈청효소 |
|---|---|---|---|
| 설명 | 혈청 내에 포함되어 있는 여러 가지 효소를 일컫는 말이다. |

| 영문 | enzyme | 한글 | 효소 |
|---|---|---|---|
| 설명 | 생물체 세포속에서 합성되고, 주로 세포내에서 진행되는 화학반응을 촉매하는 단백질로 시험관내에서도 같은 촉매작용을 한다. 이 효소는 인공적으로 만든 어떤 촉매제보다 그 특이성과 촉매작용이 탁월한 특별한 생체분자이다. 신진대사, 즉 세포내에서 일어나는 물질의 화학적 변환은 효소의 작용에 의해 매우 빠르고 원할하게 이루어진다. 이것은 효소의 촉매 효율이 높은 점과 효소의 기질 특이성 때문이다. 효소반응은 상온, 상압, 최적 pH 등 적절한 조건 아래에서 진행된다. 또 효소의 주체가 단백질이기 때문에 단백질을 변성시키는 열, 강산, 강알칼리, 유기용매 등에 의해 그 작용을 잃는다. 효소는 생체에 널리 분포하며, 복잡하고 다양한 대사반응을 촉매하기 때문에 종류도 많다. 앞서 말한 바와 같이 대부분의 효소는 세포내에 존재하지만, 혈액과 그외의 간질액에 들어 있기도 하고 소화효소류처럼 체외로 분비되는 것도 있다. |

| 영문 | enzyme-linked immunoabsorbent assay | 한글 | 효소면역측정법 |
|---|---|---|---|
| 설명 | 효소결합면역흡착제 검정법으로 번역되고 있다. 이 법은 항원(또는 항체)에 알칼리 포스파타아제 또는 페르옥시디아제 등의 산소를 결합시켜 두고 그 산소활성을 지표로 삼아 항원항체반응의 정도를 안 다음 여기에서 항원(또는 항체)의 양을 구하는 것이다. 이 법의 이점으로서 고감도, 조작의 간단함 및 방사선면역측정법처럼 방사성물질을 사용하지 않아도 된다는 점을 들 수 있다. 호르몬이나 면역글로불린의 정량법으로서 응용 되고 있으며 측정용 키트도 시판되고 이있다. |

| feedback inhibition | <biochemistry, physiology> The process of the end product of a particular metabolic reaction inhibiting an allosteric enzyme involved in that reaction as the reaction starts again, thus breaking the reaction cycle. (09 Oct 1997) |
|---|---|
| enzyme inhibition theory of narcosis | That narcotics inhibit respiratory enzymes by suppression of the formation of high energy phosphate bonds within the cell. (05 Mar 2000) |
| positive feedback | <physiology> The return of some of the output of a system as input so as to exert some control in the process. (18 Nov 1997) |
| negative feedback | This occurs where the products of a process can act at an earlier stage in the process to inhibit their own formation. The term was first used widely in conjunction with electrical amplifiers where negative feedback was applied to limit distortion of the signal by the amplification mechanism. Tends to stabilise the process. In contrast to positive feedback. (18 Nov 1997) |
| feedback | <physiology> The return of some of the output of a system as input so as to exert some control in the process. (18 Nov 1997) |
| feedback activation | The activation of an enzyme by an end product of a biochemical pathway in which that enzyme plays a part. For example, the activation of factors VIII and V by thrombin during blood clotting. (05 Mar 2000) |
| feedback control | The regulation of the activity of an enzyme by one of its products. (09 Oct 1997) |
| feedback regulation | <physiology> Control mechanism that uses the consequences of a process to regulate the rate at which the process occurs: if, for example: the products of a reaction inhibit the reaction from proceeding (or slow down the rate of the reaction), then there is negative feedback, something that is very common in metabolic pathways. Positive feedback is liable to lead to exponential increase and may be explosively dangerous in some cases. Other examples are the action of voltage dependent sodium channels in generating action potentials and the activation of blood clotting factors V and VIII by thrombin. Without damping, feedback can lead to resonance (hunting) and oscillation in the system. (18 Nov 1997) |
| feedback system | A complex of neuronal circuits whereby a part of the efferent path returns to the input to modulate its activity, thus acting as a governor on the system. See: feedback. (05 Mar 2000) |
| allogeneic inhibition | Inhibition or injury to allogeneic cells that occurs when lymphocytes are mixed and cultured with other cells of different genotypes in vitro. (05 Mar 2000) |
| macrophage inhibition factor | <cytokine> A group of lymphokines (including a 14 kD glycoprotein) produced by activated T lymphocytes that reduces macrophage mobility and probably increases macrophage macrophage adhesion. (18 Nov 1997) |
| macrophage migration inhibition test | A test which measures the presence of migration-inhibitory factor. Usually peritoneal macrophages are placed in a capillary tube in the presence or absence of supernatants from activated T-cells. If MIF is present, the migration of monocyte/macrophages is reduced. Synonym: macrophage migration inhibition test, migration inhibition test. (05 Mar 2000) |
| reactive inhibition | Tendency toward a lessened strength of response due to practice or activity. It is independent of the effect of reward and is a direct function of time interval since the last response and the number of preceding responses. (12 Dec 1998) |
| reciprocal inhibition | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reflex inhibition | A situation in which sensory stimuli decrease reflex activity. (05 Mar 2000) |
