|---|---|---|---|
| 설명 | 장기 조직을 구성하고 있는 세포가 원래의 구조는 유지하면서 수적 변동없이 그 용적만 커진 상태. 결과적으로 그 조직 장기의 용적과 중량이 불어나게 되는 것을 말한다. 이때 세포가 커진 것은 세포종창 또는 부종과 같이 수분 흡수가 증가한 것이 아니고 세포 내 구조물의 합성이 증가되기 때문이다. 비대는 생리적 혹은 병적일 수 있고 기능적 부하가 증대되거나 또는 특별한 내분비 자극에 의해 일어난다. 비대는 다음과 같이 분류할 수 있다. ① 작업비대: 운동선수의 근육, 고혈압이나 판막증의 심장근, 임신자궁의 비대 등, ② 대상성 비대: 한쪽 콩팥을 적출하였을 때 다른 쪽 콩팥에서 일어나는 비대 등, ③ 호르몬성 비대: 뇌하수체호르몬의 작용으로 거단증-거인증이 생기는 경우 등, ④ 염증성 비대: 만성염에 있어서의 위나 코안점막의 비대 등, ⑤ 특발성 비대: 다모증-비늘증-내장비대증 등과 같은 원인불명의 선천성 발육이상에 의한 비대 등이 있다. |

hyperbaric spinal anaesthesia |
Spinal anaesthesia in which spread of local anaesthetic solution in the subarachnoid space is controlled by adjusting the position of the patient when the density of local anaesthetic is made greater than the density of cerebrospinal fluid (i.e., hyperbaric) by the addition of glucose. (05 Mar 2000) |

hyperbarism |
Disturbances in the body resulting from the pressure of ambient gases at greater than 1 atmosphere; e.g., nitrogen narcosis, oxygen toxicity, bends, etc. Origin: hyper-+ G. Baros, weight (05 Mar 2000) |
hyperbasic aminoaciduria |
An inherited disorder associated with a deficiency of a dibasic amino acid transport. Individuals do not display protein intolerance. Compare: lysinuric protein intolerance. (05 Mar 2000) |
hyperbetalipoproteinaemia |
Enhanced concentration of beta-lipoproteins in the blood. (05 Mar 2000) |
hyperbilirubinaemia |
<biochemistry> A medical condition where abnormally high concentrations of the bile pigment bilirubin are found in the bloodstream. This can result in jaundice. Hyperbilirubinaemia sometimes occurs in premature babies. (09 Oct 1997) |
hyperbilirubinaemia, hereditary |
Inborn errors of bilirubin metabolism resulting in excessive amounts of bilirubin in the circulating blood, either because of increased bilirubin production or because of delayed clearance of bilirubin from the blood. (12 Dec 1998) |
hyperbola |
<geometry> A curve formed by a section of a cone, when the cutting plane makes a greater angle with the base than the side of the cone makes. It is a plane curve such that the difference of the distances from any point of it to two fixed points, called foci, is equal to a given distance. If the cutting plane be produced so as to cut the opposite cone, another curve will be formed, which is also an hyperbola. Both curves are regarded as branches of the same hyperbola. Origin: Gr, prop, an overshooting, excess, i. E, of the angle which the cutting plane makes with the base. (06 Mar 1998) |
hyperbolical |
1. <mathematics> Belonging to the hyperbola; having the nature of the hyperbola. Hyperbolic functions, a spiral curve, the law of which is, that the distance from the pole to the generating point varies inversely as the angle swept over by the radius vector. 2. Relating to, containing, or of the nature of, hyperbole; exaggerating or diminishing beyond the fact; exceeding the truth; as, an hyperbolical expression. Origin: L. Hyperbolicus, Gr., cf. F. Hyperbolique. (06 Mar 1998) |
hyperbolically |
1. <mathematics> In the form of an hyperbola. 2. With exaggeration; in a manner to express more or less than the truth. Source: Websters Dictionary (01 Mar 1998) |
hyperboloid |
<geometry> A surface of the second order, which is cut by certain planes in hyperbolas; also, the solid, bounded in part by such a surface. Hyperboloid of revolution, an hyperboloid described by an hyperbola revolving about one of its axes. The surface has two separate sheets when the axis of revolution is the transverse axis, but only one when the axis of revolution is the conjugate axis of the hyperbola. Having some property that belongs to an hyperboloid or hyperbola. (04 Mar 1998) |
hyperborean |
1. Of or pertaining to the region beyond the North wind, or to its inhabitants. 2. Northern; belonging to, or inhabiting, a region in very far north; most northern; hence, very cold; fright, as, a hyperborean coast or atmosphere. "The hyperborean or frozen sea." (C. Butler (1633)) 3. One of the people who lived beyond the North wind, in a land of perpetual sunshine. See: boreas. Origin: L. Hyperboreus, Gr.; over, beyond. (04 Mar 1998) |
hyperbrachycephaly |
An extreme degree of brachycephaly, with a cephalic index of over 85. Origin: hyper-+ G. Brachys, short, + kephale, head (05 Mar 2000) |
hypercalcaemia |
<biochemistry> A medical condition in which abnormally high concentrations of calcium compounds are found in the bloodstream. Normal blood calcium is in the range of 8.5 to 10.5 mg/dl. Elevations may be seen in hyperparathyroidism, multiple myeloma, excessive vitamin D intake, as a drug side effect (thiazide diuretics) and in association with some cancers (particularly those spread to bone). Compare: hypocalcaemia. Origin: Gr. Haima = blood (11 Jan 1998) |

Compare: hypocalcaemia. Origin: Gr. Haima = blood (11 Jan 1998) |
hypercalcinuria |
<biochemistry> The excretion of abnormally large amounts of calcium in the urine, seen in cases of hyperparathyroidism. Origin: Gr. Ouron = urine (11 Jan 1998) |
