| 설명 | 협심증은 심장동맥의 혈류를 좋게하거나 심장이 혈류에 비해서 많은 일을 하는 것을 억제함으로써 치료될 수 있다. ① nitrate계통의 약물: 혈관을 이완시키는 작용을 함으로써 심장동맥의 혈류를 좋게 한다. ② 칼슘통로차단제(verapamil, nifedipine): 모든 근육의 수축에는 Ca이 관여한다. 즉 Ca이 있어야만 근육의 수축이 가능해진다. 그러므로 Ca이 세포속으로 들어가는 것을 억제하는 약제는 근육의 수축을 막는다. 이 약은 심장의 근육에 작용하여 심장 근육의 수축을 억제하며 심장이 과도하게 일하는 것을 막고, 또 심장동맥의 수축에 관여하는 근육에 작용을 하여 심장동맥을 이완시켜서 혈류를 좋게 한다. ③ 베타차단제(beta-blocker): 신체의 운동량이나 기타의 요구에 의해서 심장을 빨리 뛰게하는 신경은 바로 베타-교감신경이다. 교감신경계란 사람이 위급한 상황에서 작용하는 자율신경계이다. 즉 사람이 긴장하거나 싸울 경우에 전형적으로 교감신경계가 작용한다. 즉 심장이 뛰거나 소화가 않되거나 동공이 커지는 것 따위가 바로 교감신경계의 역할이라고 할 수 있다. 이 교감신경계에서 말초장기에 보내는 신경이 교감신경이다. 그러므로 심장에서 심장을 신체에 필요에 따라서 많은 일을 하게하는 신경을 차단할 경우에는 협심증을 치료할 수 있게 된다(심장의 산소나 기타 영양분의 수요를 줄인다). |

| head protective devices | Personal devices for protection of heads from impact, penetration from falling and flying objects, and from limited electric shock and burn. (12 Dec 1998) |
| protective | <pharmacology> An agent that affords defense against a deleterious influence, such as a substance applied to the skin to avoid the effects of the sun's rays or other noxious influences. Origin: L. Protegere = to cover over (18 Nov 1997) |
| protective agents | Synthetic or natural substances which are given to prevent a disease or disorder or are used in the process of treating a disease or injury due to a poisonous agent. (12 Dec 1998) |
| protective block | An incompletely understood mechanism whereby a pacemaker is protected from being discharged by the impulse from another centre; the mechanism, usually conceived as an encircling zone of unidirectionally refractory tissue permitting egress of impulses from the centre but preventing access to the centre, is seen in operation in ventricular parasystole where the parasystolic centre is protected from discharge by the sinus pacemaker and so is able to maintain its intrinsic rhythm undisturbed. Synonym: entrance block, protection. (05 Mar 2000) |
| protective clothing | Clothing designed to protect the individual against known hazards to which he will be exposed. (12 Dec 1998) |
| protective colloid | A colloid that has the power of preventing the precipitation of suspensoids under the influence of an electrolyte. (05 Mar 2000) |
| protective devices | Devices designed to provide personal protection against injury to individuals exposed to hazards in industry, sports, aviation, or daily activities. (12 Dec 1998) |
| protective laryngeal reflex | Closure of the glottis to prevent entry of foreign substances into the respiratory tract. (05 Mar 2000) |
| protective protein | An immunoglobulin molecule that has a specific amino acid sequence by virtue of which it interacts only with the antigen that induced its synthesis in cells of the lymphoid series (especially plasma cells) or with antigen closely related to it. Antibodies are classified according to their ode of action as agglutinins, bacteriolysins, haemolysins, opsonins, precipitins, etc. (18 Nov 1997) |
| protective spectacles | Spectacles which protect against ultraviolet or infrared rays or against mechanical injuries. Synonym: safety spectacles. (05 Mar 2000) |
| protective zone | The time in the cardiac cycle, immediately following the vulnerable period, during which a second stimulus will prevent the initiation of ventricular fibrillation by a previous stimulus applied during the vulnerable period, probably by blocking a reentrant pathway. (05 Mar 2000) |
| ear protective devices | Personal devices for protection of the ears from loud or high intensity noise, water, or cold. These include earmuffs and earplugs. (12 Dec 1998) |

| abnormalities, drug-induced | Congenital abnormalities caused by medicinal substances or drugs of abuse given to or taken by the mother, or to which she is inadvertently exposed during the manufacture of such substances. The concept excludes abnormalities resulting from exposure to non-medicinal chemicals in the environment. (12 Dec 1998) |
