| 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 mantle | Origin: L. See Pall the garment. 1. A large, square, woolen cloak which enveloped the whole person, worn by the Greeks and by certain Romans. It is the Roman name of a Greek garment. 2. A band of white wool, worn on the shoulders, with four purple crosses worked on it; a pall. The wool is obtained from two lambs brought to the basilica of St. Agnes, Rome, and blessed. It is worn by the pope, and sent to patriarchs, primates, and archbishops, as a sign that they share in the plenitude of the episcopal office. Befoer it is sent, the pallium is laid on the tomb of St. Peter, where it remains all night. 3. <zoology> The mantle of a bivalve. See Mantle. The mantle of a bird.

| brain metastases | <oncology, radiology> 10% of intracranial mass lesions are metastasis, 10-38% of patients with systemic cancer have brain metastasis: adults: lung, breast, GU tract, colon/rectum, melanoma, sinuses. children: neuroblastoma, embryonal rhabdomyosarcoma, Wilms tumour. Location: most in middle cerebral artery distribution at the cortex, 20% in posterior fossa. See also: haemorrhagic metastasis. (08 Mar 2000) |
| brain murmur | <neurology> Sounds produced by intracranial aneurysms or arterial venous aneurysms in congenital dysplastic angiomatosis. (05 Mar 2000) |
| brain natriuretic peptide | <hormone, protein> Brain peptide that induces diuresis, related to atrial natriuretic peptide. (18 Nov 1997) |
| brain neoplasm | Neoplasms of the part of the central nervous system contained within the cranium. (12 Dec 1998) |
| brain oedema | Brain swelling due to increased volume of the extravascular compartment from the uptake of water in the neuropile and white matter. See: brain swelling. Synonym: brain oedema. (05 Mar 2000) |
| brain potential | <physiology> The electrical charge of the brain as compared to a point on the body; the potential may be steady (DC potential) or may fluctuate at specific frequencies when recorded against time, giving rise to the electroencephalogram. (05 Mar 2000) |
| brain sand | Small calcareous concretions in the stroma of the pineal and other central nervous system tissues. Synonym: acervulus, brain sand, psammoma bodies. (05 Mar 2000) |
| brain-specific kinase | <enzyme> Expressed specifically in brain; member of the eph/elk receptor-like kinase family; mw 105 kD; may represent murine homolog of chicken cek7 receptor-like kinase; amino acid sequence given in first source Registry number: EC 2.7.1.- Synonym: bsk tyrosine kinase (26 Jun 1999) |
| Brain's reflex | Extension of the arm of a hemiplegic patient when turned prone as if on all fours. Synonym: Brain's reflex. (05 Mar 2000) |
| brain tissue transplantation | Transference of brain tissue, either from a foetus or from a born individual, between individuals of the same species or between individuals of different species. (12 Dec 1998) |
| brain tumour | <oncology, tumour> May be subdivided into primary brain tumours and the more common, secondary brain tumours. Primary brain tumours (for example astrocytoma, craniopharyngioma, glioma, ependymoma, neuroglioma, oligodendroglioma, glioblastoma multiforme, meningioma, medulloblastoma) arise from the uncontrolled proliferation of cells within the brain. Secondary brain tumours occur from the spread of cancer into the brain from a distant cancerous organ (metastasis). Common symptoms of a brain tumour include headache, nausea, vomiting, seizures, change in mentation, neurologic symptoms and loss of memory. (17 Dec 1997) |
| brain tumour calcifications | <radiology> Oligodendroglioma (90%), craniopharyngioma (70%), ependymoma (60%), choroid plexus papilloma (25%), low-grade astrocytoma (20%), meningioma (10%), others, dermoid, pineal tumours, lipoma, caveat: a calcified intraparenchymal tumour is most likely to be an astrocytoma due to higher overall incidence relative to other tumours mentioned above.
