| 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. |

| brain wave test | <investigation> A diagnostic test which measures the electrical activity of the brain (brain waves) using high sensitive recording equipment attached to the scalp by fine electrodes. Commonly employed in the evaluation of neurological disease (for example seizures, epilepsy, etc.). Acronym: EEG (13 Nov 1997) |
| Brain, W Russell Lord | <person> English physician, 1895-1966. See: Brain's reflex. (05 Mar 2000) |
| bulb of posterior horn of lateral ventricle of brain | Bulb of posterior horn of lateral ventricle of the brain; a curved elevation on the inner wall of the posterior horn produced by the fibres of the forceps major of the corpus callosum as they bend backward into the occipital lobe. Synonym: bulb of posterior horn of lateral ventricle of brain. (05 Mar 2000) |
| cancer, brain | Cancer of the central information processing centre of the body. Tumours in the brain can be malignant or benign and can occur at any age. Primary brain tumours initially form in the brain tissue. Secondary brain tumours are cancers that have spread to the brain tissue (metastasized) from elsewhere in the body. (12 Dec 1998) |
| visceral brain | Collective term denoting a heterogeneous array of brain structures at or near the edge (limbus) of the medial wall of the cerebral hemisphere, in particular the hippocampus, amygdala, and fornicate gyrus; the term is often used so as to include also the interconnections of these structures, as well as their connections with the septal area, the hypothalamus, and a medial zone of mesencephalic tegmentum. By way of the latter connections, the limbic system exerts an important influence upon the endocrine and autonomic motor system's; its functions also appear to affect motivational and mood states. Synonym: visceral brain. (05 Mar 2000) |
| medullary arteries of brain | Branches of the cortical artery's which penetrate to and supply the white matter of the cerebrum. (05 Mar 2000) |
| respirator brain | A swollen and congested brain with necrotic and autolytic changes seen in patients who have been on a respirator. (05 Mar 2000) |
| ring lesions in brain | <radiology> Hypodense, peripherally enhancing lesions, ** mnemonic: MAGIC DR., metastasis, abscess, glioma, granuloma, infarct, contusion, demyelination, resolving haematoma (12 Dec 1998) |
| metastatic brain tumour | A malignant growth in brain tissue that has spread from another primary cancer site (for example breast cancer, malignant melanoma, lung cancer) in the body. (27 Sep 1997) |
| gyral brain calcification | <radiology> Sturge-Weber-Dimitri syndrome, treated CNS lymphoma, post-meningoencephalitis, brain tumour (oligodendroglioma) (12 Dec 1998) |
| minimal brain dysfunction | An inability to control behaviour due to difficulty in processing neural stimuli. (12 Dec 1998) |
