| 설명 | 조절할 수 없이 계속 진행되는 세포분열에 의한 조직의 새로운 증식 및 증대. 신생물. (1) 분류 A. 침윤과 전이의 유무에 따라 i)양성종양: 침윤과 전이가 없고 역형성이 낮은 세포로 구성됨. 대개 치료에 반응이 높고, 생명에 크게 지장이 없으며, 재발하는 경우도 적다. 증상은 단지 주위조직에 대한 압박정도이다. ii)악성종양: 침윤과 전이가 있고 퇴화도가 높은 세포로 구성됨. 기원세포가 상피조직일 경우 암종, 비상피성일 경우 육종으로 나누기도 한다. 치료에 잘 반응하지 않고, 재발을 잘 하며, 생존율이 낮다. 흔히 말하는 “암”을 의미한다. B. 조직학적 특징에 따라 샘종, 지방종, 근종 등으로 나누기도 한다. (2) 병리조직학적 특징 A. 육안적 소견 덩어리를 형성하기도 하고 정상조직에 스며들듯이 판상구조를 이루기도 하는 등 다양한 형태를 보인다. 양성의 경우 피막을 가진 경우가 많고 악성의 경우 없는 경우가 많다. 육안소견에 따라 다음과 같이 나눈다. 낭성, 융기성, 괴사성, 폴립모양, 궤양형 등이 있다. 또는 세포의 크기와 모양이 비정상적인 형태로 변화한다. 핵의 극성이 사라지고 핵의 염색성이 짙어진다. 세포질의 염색성도 변화하며 세포들간의 세포주기가 매우 다양해져 많은 세포분열을 보인다. 이러한 일련의 변화를 역형성이라 한다. 역형성의 정도에 따라 조직학적 등급을 나눈다. 또한 각 종양에 따라 각기 다른 병리조직학적 명칭을 붙인다. |

| control arm | The group of participants in a clinical trial who receive standard treatment or a placebo, against which those receiving the experimental treatment are compared. (09 Oct 1997) |
|---|---|
| control element | Generic term for a region of DNA, such as a promoter or enhancer adjacent to (or within) a gene that allows the regulation of gene expression by the binding of transcription factors. (18 Nov 1997) |
| control experiment | An experiment used to check another, to verify the result, or to demonstrate what would have occurred had the factor under study been omitted. See: control, control animal. (05 Mar 2000) |
| control gene | See: operator gene, regulator gene. (05 Mar 2000) |
| control group | A group of subjects participating in the same experiment as another group of subjects, but which is not exposed to the variable under investigation. See: experimental group. (05 Mar 2000) |
| control limit | A regulatory value applied to the airborne concentration in the workplace of a potentially poisonous substance which is judged to be reasonably practicable for the whole spectrum of work activities and which must not normally be exceeded. (09 Oct 1997) |
| Control of Communicable Diseases in Man | The internationally recognised authoritative manual now in the 15th (1990) edition, published by the American Public Health Association. (05 Mar 2000) |
| control plot | A plot in which no vegetation will be cut and natural succession will occur. A control plot serves as a baseline to compare other treatments (Early, Mid and Late Seral). (05 Dec 1998) |
| control release suture | Eyeless suture with thread attached to needle such that the two separate when tension is applied to the thread. (05 Mar 2000) |
| control syringe | A type of Luer-Lok syringe with thumb and finger rings attached to the proximal end of the barrel and to the tip of the plunger, allowing operation of the syringe with one hand. Synonym: ring syringe. (05 Mar 2000) |
| poison control centres | Facilities which provide information concerning poisons and treatment of poisoning in emergencies. (12 Dec 1998) |
| cost control | The containment, regulation, or restraint of costs. Costs are said to be contained when the value of resources committed to an activity is not considered excessive. This determination is frequently subjective and dependent upon the specific geographic area of the activity being measured. (12 Dec 1998) |
| population control | Includes mechanisms or programs which control the numbers of individuals in a population of humans or animals. (12 Dec 1998) |
| positive control | Mechanism for gene regulation that requires that a regulatory protein must interact with some region of the gene before transcription can be activated. (18 Nov 1997) |
| self-control | 1. Self-regulation of one's behaviour in accordance with personal beliefs, goals, attitudes and societal expectations. 2. Use by an individual of active coping strategies to deal with problem situations, in contrast to passive conditioning strategies which do things to the individual and require no action by the person.
