| 설명 | 신체를 싸고 있는 바깥층으로서 표피, 진피, 피하조직으로 구성되며, 외부 환경으로부터 신체를 보호하고 체온을 조절하는 기능을 가짐. 1.표피: 피부의 가장 바깥층으로서 외배엽에서 기원하며 각질이라는 구조 단백질을 생산하는 기능을 가짐. 4가지의 세포가 있는데, 각질세포, 멜라닌세포, Langerhans 세포, 부정형 세포, Merkel세포가 있다. 표피에는 이 4가지 세포외에 다음과 같은 표피 부속기가 있다. 에크린 땀샘(eccrine sweat gland): 점막 피부 경계 부위 등 특수한 부위를 제외한 모든 피부에서 발견되며 땀을 분비하는 샘으로서 신체 열 조절 체계의 중요한 요소. 아포크린샘(apocrine gland): 겨드랑이, 젖꽃판, 항문 생식기 부위, 외이도, 눈꺼풀 등에서만 발견되며 분비물의 기능은 잘 알려져 있지 않으나 동물에서는 방어 및 성적 기능이 있음. 털주머니(hair follicle): 손바닥, 발바닥 등 특수 부위를 제외한 신체 전 부위에 분포하며 인간에서 중요한 생리적 기능은 없으나 성적 매력을 지니는 신체 장식의 기능을 가짐. 기름샘(sebaceous gland): 손바닥과 발바닥을 제외한 전 피부에 분포하며 분비물을 기름(sebum)라 부름. 남성 호르몬의 자극에 의해 성장하며 생리적 기능은 잘 알려져 있지 않음. 손발톱(nail) 2. 진피: 표피 아래에 존재하는 중배엽 기원의 조직으로서 혈관, 림프관, 신경, 근육, 표피 부속기 등을 포함하고 있음. 표피 바로 밑의 부위를 유두 진피라 하고 아래층을 망상 진피라 한다. 조직 섬유에는 아교질 섬유, 그물 섬유, 탄력 섬유의 세 종류가 있다. 3. 피하 조직: 진피 아래에 존재하며 중배엽 기원으로서 보온 작용, 충격 흡수 작용, 영양 저장 작용의 기능이 있다. |

| adrenergic blocking agent | A compound that selectively blocks or inhibits responses to sympathetic adrenergic nerve activity (sympatholytic agent) and to epinephrine, norepinephrine, and other adrenergic amines (adrenolytic agent); two distinct classes exist, alpha-and beta-adrenergic receptor blocking agent's. (05 Mar 2000) |
| adrenergic neuronal blocking agent | A drug that prevents the release of norepinephrine from sympathetic nerve terminals; it does not inhibit the responses of the adrenergic receptors to circulating epinephrine, norepinephrine, and other adrenergic amines. (05 Mar 2000) |
| agent | <pharmacology> Any power, principle or substance capable of producing an effect, whether physical, chemical or biological. Origin: L. Agens = acting (18 Nov 1997) |
| agent, antihypertensive | As the name suggests, a drug aimed at reducing high blood pressure (hypertension). (12 Dec 1998) |
| agent, anti-infective | Something capable of acting against infection, by inhibiting the spread of an infectious agent or by killing the infectious agent outright. (12 Dec 1998) |
| Agent Orange | An herbicide and defoliant, consisting of (2,4,5-trichlorophenoxy)acetic acid, (2,4-dichlorophenoxy)acetic acid, and dioxin, that was widely used in the Vietnam War; it has been shown to possess residual post-exposure carcinogenic and teratogenic properties in humans. (05 Mar 2000) |
| agent, tocolytic | A medication that can inhibit labour, slow down or halt the contractions of the uterus. Tocolytic agents are widely used today to treat premature labour and permit pregnancy to procede and so let the foetus gain in size and maturity before being born. (12 Dec 1998) |
| alkylating agent | <oncology, pharmacology> A reagent that places an alkyl group, for example propyl in place of a nucleophilic group in a molecule. Alkylating reagents include a number of cytotoxic drugs some of which react fairly specifically with N7 of the purine ring and lead to depurination of DNA, for example the agent ethyl ethanesulphonic acid and thus to mutagenesis. The drugs interaction with DNAand prevents the division of the cells. Examples of drugs include: busulphan, chlorambucil, cyclophosphamide, melphalan. (29 Sep 1997) |
| alpha-adrenergic blocking agent | An agent that competitively blocks alpha-adrenergic receptors; used in the treatment of hypertension. Synonym: alpha-blocker. (05 Mar 2000) |
| antianxiety agent | A functional category of drugs useful in the treatment of anxiety and able to reduce anxiety at doses which do not cause excessive sedation (e.g., diazepam). Synonym: anxiolytic, minor tranquilliser. (05 Mar 2000) |
| antidiabetic agent | A substance that helps a person with diabetes control the level of glucose (sugar) in the blood so that the body works as it should. See: insulin. (09 Oct 1997) |
| antifibrinolytic agent | Agents that prevent fibrinolysis or lysis of a blood clot or thrombus. Several endogenous antiplasmins are known. The drugs are used to control massive haemorrhage and in other coagulation disorders. (12 Dec 1998) |
| antifoam agent | A chemical that reduces the surface tension of foams that form on thesurface of broths in fermentors because of aeration or agitation. Stearyldecanol, octal decanol, vegetable oils, silicones, sulphonates, andpolypropylene glycol are typically used, though they can cause problems inrefining the broth later on. (09 Oct 1997) |
| anti-inflammatory agent | Agents that counteract or suppress the inflammatory process. An antirheumatic agent or inflammation mediator, both endogenous and exogenous substances used to counteract the inflammatory process or alleviate or prevent rheumatic diseases, and the compounds that mediate the inflammation process.
