| 설명 | 선천심장병중의 하나. 태아가 뱃속에 있을 때는 혈액의 흐름이 출생후의 혈액순환과는 다르다. 태아는 호흡을 할 수 없으므로 산소가 있는 혈액을 단지 산모의 혈액에서만 구할 수 있다. 산모의 자궁동맥을 통해 태아의 배꼽정맥으로 넘어간 산화혈액은 간에서 정맥관(ductus venosus)을 거친뒤 심장에 이르게 된다. 심장에 이르른 혈액은 일부는 오른심방에서 곧바로 왼심방으로 가서 다시 좌심실을 거친뒤 대동맥으로 통하게 되지만, 일부는 우심방에서 우심실, 그리고 우심실에서 폐동맥으로 가는 정상출산아와 비슷한 혈액의 경로를 밟는다. 이때 폐는 자궁내에서는 호흡을 할 수 없으므로 폐의 작용이 없게 되고, 따라서 폐동맥으로 건너간 혈액은 폐를 거치지 않고 동맥관(ductus arteriosus)을 통해 곧바로 동맥에 이른다. 이런 태아의 순환은 출생후 호흡이 시작되면, 정상적인 출생 후의 순환으로 바뀌게 된다. 이 경우 태아순환에서만 존재하는 정맥관과 동맥관은 자연히 막히게 되고, 우심방에서 좌심방으로 흐르던 혈액의 순환은 없어진다. 그러나, 경우에 따라 태아순환에서만 유지되는 동맥관이 막히지 않는 병적인 상태가 발생하는데, 주로 미숙아, 혹은 선천성 바이러스 감염 등이 원인으로 추정된다. 이런 경우를 동맥관개존증이라 부르고, 심장은 불필요한 혈액의 흐름을 부담해야 하므로 일찍 심장기능상실(cardiac failure)에 빠지기 쉽다. 열려있는 동맥관의 크기가 작으면, 증상이 가벼워 늦게 치료해도 되지만, 큰 동맥관개존증은 빠른 수술적 치료를 하여야 한다. 일부에서는 저절로 막히기도 한다. |

| 영문 | incubation period, latent stage | 한글 | 잠복기, 배양기간 |
|---|---|---|---|
| 설명 | 1. 병원체가 체내에 침입(감염)한 후 그로 인한 감염증이 발병할 때까지의 기간. 병원체의 종류에 따라 그 내용이 다르다. 예컨대 말라리아는 침입한 병원체가 인체 내에서 일정한 단계까지 발육한 후 발병하고, 장티푸스는 침입한 병원균이 일정한 수까지 번식을 해야 발병하며, 파상풍은 침입한 병원균이 생성한 독소가 뇌신경에 달한 후에 발병한다. 같은 병이라도 침입한 병원체의 양이나 독력, 감염된 사람의 감수성 등에 따라서도 달라진다. 보통 잠복기에는 병적 징후가 나타나지 않지만 민감한 사람의 경우는 두통-식욕부진-현기증-불쾌감과 같은 전구증상을 나타내는 수도 있다. 2. 보온기간, 배양기간, 발육에 필요한 기간. |

| patent | 1. 2. Open to public perusal; said of a document conferring some right or privilege; as, letters patent. See Letters patent, under 3d Letter. 3. Appropriated or protected by letters patent; secured by official authority to the exclusive possession, control, and disposal of some person or party; patented; as, a patent right; patent medicines. "Madder . . . In King Charles the First's time, was made a patent commodity." (Mortimer) 4. <botany> Spreading; forming a nearly right angle with the steam or branch; as, a patent leaf. Patent leather, a varnished or lacquered leather, used for boots and shoes, and in carriage and harness work. Patent office, a government bureau for the examination of inventions and the granting of patents. Patent right. The exclusive right to an invention, and the control of its manufacture. The right, granted by the sovereign, of exclusive control of some business of manufacture, or of the sale of certain articles, or of certain offices or prerogatives.

| patent blue V | A sulfonated triphenylmethane dye reduced and decolorised with zinc and acetic acid to produce a stable solution; used to demonstrate haemoglobin peroxidase. Synonym: patent blue V. (05 Mar 2000) |
| patent ductus arteriosus | <cardiology, embryology, paediatrics> A condition where the normal channel between the pulmonary artery and the aorta fails to close at birth. In normal foetal circulation the blood bypasses the pulmonary circuit since oxygen and nutrients are acquired through the placenta. After birth, this channel normally closes in response to ventilation of the lungs. Those who are affected may demonstrate poor growth, shortness of breath and rapid respiratory rate. Diagnosis is by echocardiogram and treatment involves the use of indomethacin to stimulate ductus arteriosus closure. Surgical ligation will be required in those cases unresponsive to medical management. (27 Sep 1997) |
| patent medicine | A medicine, usually originally patented, advertised to the public. (05 Mar 2000) |
| ductus arteriosus, patent | Abnormal persistence of an open lumen in the ductus arteriosus after birth, the direction of flow being from the aorta to the pulmonary artery, resulting in recirculation of arterial blood through the lungs. (12 Dec 1998) |
| erecto-patent | 1. <botany> Having a position intermediate between erect and patent, or spreading. 2. <entomology> Standing partially spread and erect; said of the wings of certain insects. Source: Websters Dictionary (01 Mar 1998) |
| ureteric branches of the patent part of umbilical artery | <anatomy, artery> Supplies pelvic portion of ureter. Synonym: rami ureterici partis patentis arteriae umbilicale. (05 Mar 2000) |
| leuco patent blue | A sulfonated triphenylmethane dye reduced and decolorised with zinc and acetic acid to produce a stable solution; used to demonstrate haemoglobin peroxidase. Synonym: patent blue V. (05 Mar 2000) |
| absolute refractory period | The period following excitation when no response is possible regardless of the intensity of the stimulus. (05 Mar 2000) |

| anaesthesia recovery period | The period of emergence from general anaesthesia, where different elements of consciousness return at different rates. (12 Dec 1998) |
| Gap1 period | The period of the cell cycle after cell division when there is synthesis of RNA and protein; it may last for a few hours in rapidly growing tissue or a lifetime in non-renewing cells such as nerve cells. Synonym: Gap1 phase, postmitotic phase. (05 Mar 2000) |
| Gap2 period | The period in the cell cycle when synthesis of DNA is completed but before mitosis begins. Synonym: Gap2 phase, premitotic phase. (05 Mar 2000) |
| masticatory silent period | A pause in electromyographic patterns associated with tooth contacts during chewing and biting; a part of the complex feedback mechanism of mandibular control involving receptors in the periodontal ligament and muscles. (05 Mar 2000) |
| refractory period | <neurology, physiology> most commonly used in reference to the interval (typically 1ms) after the passage of an action potential during which an axon is incapable of responding to another. This is caused by inactivation of the sodium channels after opening. The maximum frequency at which neurons can fire is thus limited to a few hundred Hertz. An analogous refractory period occurs in individuals of Dictyostelium discoideum, which are insensitive to extracellular cyclic AMP immediately after a pulse of cAMP has been secreted. The term can be applied to any system where a similar insensitive period follows stimulation. (18 Nov 1997) |
