| 영문 | heart-lung machine | 한글 | 심장-허파 기계 |
|---|---|---|---|
| 설명 | 심장의 수술에 사용되는 기계로서 심장이 수술을 받고 있는 동안 기능을 하지 못하므로 이 기능을 대신 해주는 기계이다. 이것은 대정맥과 대동맥사이에 연결이 되어서 혈액을 강제로 순환시키면서 대정맥에서 온 피에 산소를 공급하여 대동맥으로 돌려 보내는 역할을 한다. 즉 심장과 폐의 역할을 동시에 하는 기계이다. |

| 영문 | congestive heart failure | 한글 | 울혈성심장기능상실 |
|---|---|---|---|
| 설명 | 심장의 원래 기능, 즉 혈액을 말초로 보내는 펌프와 같은 기능이 거의 없어진 상태를 말한다. 피를 보내는 펌프의 역할이 멈추었으므로 심장으로 들어오는 피는 심장으로 들어오지 못하고 정맥속에서 정체하게 된다. 그리하여 혈액의 대부분이 말초의 정맥에 머물게 되어 여러 가지 증상이 나타난다. 특히 허파를 돌아 좌심방으로 들어가야하는 피가 펌프 기능이 없어져서 왼심방에 많은 피가 정체하고 있어서 들어가지 못해서 허파에 고이게 된다. 그러면 허파에 산소와 이산화탄소를 교환하는 기능이 없어져서 숨을 쉬지 못하는 결과를 낸다. 즉 숨이 차고 숨쉬기 힘든 증세가 나타난다. 또 온몸을 순환한 다음에 우심방으로 들어와야하는 피도 우심방으로 들어오지 못해서 말초에 정체하므로 온몸이 붓게 된다. |

| second-order conditioning | The use of a previously successfully conditioned stimulus as the unconditioned stimulus for further conditioning. (05 Mar 2000) |
| second-order kinetics | A term describing the reaction rate of a chemical reaction in which the rate is proportional to the product of the concentrations (in moles) of two of the reactants (also called bimolecular kinetics), or to the square of the molar concentration of the reactant if there is only one. Such a reaction might have an equation like rate = k[A][B] or rate = k[A]2, where k is the reaction rate constant, [A] is the concentration of reactant A, and [B] is the concentration of reactant B.

| second parallel pelvic plane | The plane extending from the middle of the posterior surface of the pubic symphysis to the junction of the second and third sacral vertebrae, and laterally passing through the ischial bones over the middle of the acetabulum. Synonym: second parallel pelvic plane, wide plane. (05 Mar 2000) |
| second set rejection | An accelerated rejection of a transplant that occurs when an individual has been previously sensitised to the graft. (05 Mar 2000) |
| second sight | 1. <ophthalmology> Improved near vision in the aged as a result of increased refractivity of the nucleus of the lens causing myopia. Synonym: senile lenticular myopia. 2. The power of discerning what is not visible to the physical eye, or of foreseeing future events. Such as are of a disastrous kind, the capacity of a seer or prophetic vision.

| second signaling system | <psychology> Pavlovian term for speech in which words are considered to be the second signals capable of producing conditioned responses. (05 Mar 2000) |
| second-stability region | <radiobiology> A high pressure region where the plasma becomes stable to the pressure-gradient-driven ballooning instability. The plasma is stable in the limit of small pressure gradients, becomes unstable at some intermediate pressure, and then becomes stable again at still higher pressures. Tokamaks operating in the second-stability region would be more attractive because the higher pressures (beta) would provide more fusion reactivity per unit volume of plasma, allowing smaller reactors to be built. (09 Oct 1997) |
| second stage of labour | <obstetrics> The part of labour from the full dilatation of the cervix until the baby is completely out of the birth canal. The second stage of labour is also called the stage of expulsion. (12 Dec 1998) |
| second temporal convolution | A longitudinal gyrus on the lateral surface of the temporal lobe, between the superior and inferior temporal sulci. Synonym: gyrus temporalis medius, middle temporal convolution, second temporal convolution. (05 Mar 2000) |
| second tibial muscle | An inconstant muscle, of small size, arising from the back of the tibia and inserted into the articular capsule of the ankle joint. Synonym: second tibial muscle. (05 Mar 2000) |
| second tooth | One of the 32 teeth belonging to the second or permanent dentition; eruption of the permanent teeth begins from the fifth to the seventh year, and is not completed until the seventeenth to the twenty-third year, when the last of the wisdom teeth appears. Synonym: dens permanens, dens succedaneus, second tooth, secondary dentition, succedaneous dentition, succedaneous tooth. (05 Mar 2000) |
| neoplasms, second primary | Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause. (12 Dec 1998) |
| error of the second kind | See: Error, beta. (12 Dec 1998) |
| twelfth-second | <physics> A unit for the measurement of small intervals of time, such that 10^12 (ten trillion) of these units make one second. Source: Websters Dictionary (01 Mar 1998) |
