| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| milk let-down reflex | Release of milk from the breast following tactile stimulation of the nipple; the afferent path is postulated to exist from the nipple to the hypothalamus; the efferent limb is represented by the neurohypophysial release of oxytocin into the systemic circulation; contraction of myoepithelial elements within the breast, caused by oxytocin, moves milk into the collecting ducts and toward the nipple. Synonym: let-down reflex, milk let-down reflex. (05 Mar 2000) |

| milk line | Bandlike thickening of ectoderm in the embryo extending on either side from just below the axilla to the inguinal region; in human embryos, the mammary glands arise from primordia in the thoracic part of the ridge, the balance of the ridge disappearing; in some lower mammals which give birth to a litter of young, several milk glands develop along these lines. Synonym: mammary fold, milk line, milk ridge. (05 Mar 2000) |
| milk of bismuth | A suspension of bismuth hydroxide and bismuth subcarbonate in water; used in gastrointestinal disorders as a protective agent. (05 Mar 2000) |
| milk of calcium | Densely calcified fluid, most often found radiographically in the gallbladder in association with chronic obstruction. (05 Mar 2000) |
| milk of magnesia | Mixture of magnesium hydroxide; an aqueous solution of magnesium hydroxide, used as an antacid and laxative. Synonym: magnesia magma. (05 Mar 2000) |
| milk of sulfur | Sublimed sulfur boiled with lime water, the lime being removed from the precipitate by washing with diluted hydrochloric acid; used in preparing sulfur ointment and in the treatment of various skin disorders. Synonym: lac sulfuris, milk of sulfur. (05 Mar 2000) |
| milk proteins | The major protein constituents of milk are caseins and whey proteins such as lactalbumin and lactoglobulins. Immunoglobulins occur in high concentrations in colostrum and in relatively lower concentrations in milk. (12 Dec 1998) |
| milk ridge | Bandlike thickening of ectoderm in the embryo extending on either side from just below the axilla to the inguinal region; in human embryos, the mammary glands arise from primordia in the thoracic part of the ridge, the balance of the ridge disappearing; in some lower mammals which give birth to a litter of young, several milk glands develop along these lines. Synonym: mammary fold, milk line, milk ridge. (05 Mar 2000) |
| milk-ring test | A special form of agglutination test done on the pooled milk of many cows, usually entire herds, for the detection of herds containing individuals infected with bovine brucellosis. (05 Mar 2000) |
| milk scall | Seborrhoea of the scalp in an infant. Synonym: milk crust, milk scall. (05 Mar 2000) |
| milk sickness | An acute, often fatal disease caused by the ingestion of milk, milk products, or the flesh of cattle or sheep which have a disease known as trembles. It is marked by weakness, anorexia, vomiting, constipation, and sometimes muscular tremors. It is caused by poisoning by white snakeroot (eupatorium rugosum) and the rayless goldenrod (haplopappus heterophyllus). (12 Dec 1998) |
| milk spots | White plaques of hyalinised fibrous tissue situated in the epicardium overlying the right ventricle of the heart where it is not covered by lung. Synonym: soldier's patches. White macroscopic areas in the omentum, due to accumulation of macrophages and lymphocytes. Synonym: tache laiteuse. (05 Mar 2000) |
