| 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. |

| Centers for Disease Control and Prevention | <organisation> The U.S. Public health agency serving as the centre for preventing, tracking controlling and investigating the epidemiology of AIDS and other diseases. (26 Mar 1998) |

| reproductive control agents | Substances used either in the prevention or facilitation of pregnancy. (12 Dec 1998) |
| Centres for Disease Control | The federal facility for disease eradication, epidemiology, and education headquartered in Atlanta, Georgia, which encompasses the Centre for Infectious Diseases, Centre for Environmental Health, Centre for Health Promotion and Education, Centre for Prevention Services, Centre for Professional Development and Training, and Centre for Occupational Safety and Health. Formerly named Centre for Disease Control (1970), Communicable Disease Centre (1946). (05 Mar 2000) |
| centres for disease control and prevention | See: CDC. (12 Dec 1998) |
| riot control agents, chemical | Chemical substances which are employed during a riot in order to control or disperse the rioting parties. (12 Dec 1998) |
| growth control | <cell biology> When applied to cells usually means control of growth of the population, i.e. Of the rate of division rather than of the size of an individual cell. (18 Nov 1997) |
| pest control | The reduction or regulation of the population of noxious, destructive, or dangerous insects or other animals. (12 Dec 1998) |
| pest control, biological | The use of biological mechanisms, usually involving living organisms such as bacteria, for the reduction or regulation of the population of noxious, destructive, or dangerous pests. Environmental concerns have focused attention on natural forms of disease control as potentially safe and effective alternatives to chemical pesticides. This has led to increased efforts to develop control strategies that rely on natural predators and parasites or that involve genetically engineered microbial pest control agents. (12 Dec 1998) |
| rodent control | The reduction or regulation of the population of noxious, destructive, or dangerous rodents through chemical, biological, or other means. (12 Dec 1998) |
| weed control | <botany> Mechanical or chemical control of unwanted plants. Measures which have to be undertaken in a plant community to guarantee the growth of the desired vegetation. See: herbicide. (09 Oct 1997) |
| communicable disease control | Programs of surveillance designed to prevent the transmission of disease by any means from person to person or from animal to man. (12 Dec 1998) |
| mosquito control | The reduction or regulation of the population of mosquitoes through chemical, biological, or other means. (12 Dec 1998) |
| control | In research, control subjects or control procedures permit comparison with experimental results. The first controlled clinical research was probably done in 1875 by the British naval surgeon James Lind who, on board the HMS Salisbury, gave sailors with scurvy either oranges or lemons or cider or vinegar or nutmeg (or another treatment) and after just six days discovered that the citrus-consuming sailors had recovered from scury, until then the scourge of extended sea voyages, while the sailors who had been given the other treatments remained uncured. (12 Dec 1998) |
| control animal | In research, an animal submitted to the same conditions as the others used for the experiment, but with the crucial factor (such as the injection of antitoxin, the administration of a drug, etc.) omitted. See: control, control experiment. (05 Mar 2000) |
| 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) |
