| 설명 | 나이 먹는다는 의미로 사용되기도 하지만 일반적으로는 성장이 완료, 정지되고 그 이후에 일어나는 모든 과정을 가리킨다. 나이를 먹어감에 따라 생체의 여러 가지 기능이 저하되는데, 일반적으로 세포에 색소가 축적되거나 세포자체나 핵이 작아지는 현상이다. 개개의 세포 기능도 저하되고, 세포 내에 색소가 침착되며, 기관은 암갈색을 띤다. 또한 피부는 얇아지고 털주머니도 위축되며, 모발은 색소를 잃고 탈모된다. 현재 많은 학자들은 세포내 DNA가 끊어지거나 끊어진 경우 수복력이 감소하거나, 면역력이 저하하기 때문으로 보고 있다. 노화가 일어나는 것은 세포의 종류에 따라서 크게 다른데 신경세포처럼 태어나서 죽을 때까지 세포분열하지 않는 세포는 노화가 두드러지고 고환이나 골수의 세포처럼 항상 분열하는 세포는 노화현상이 거의 일어나지 않는다. 발병과 죽음의 확률이 높아지지만, 노쇠성 변화와 병적 변화와의 경제는 명확하지 않다. 노쇠를 야기하는 노화의 본질적 원인에 대해서는 아직 정설이 없다. |

|---|---|---|---|
| 설명 | X-선 사진에서 잘 나타나는 조영제(방사선촬영상에서 하얗게 나타나 주위조직과 감별이 용이하다)를 섭취한 후 식도, 위, 샘창자, 작은창자상부까지 X-선 촬영하므로써, 그곳 소화관내의 이상병터여부를 검사하는 것. 조영제는 주로 바륨을 사용하며 더 선명한 영상을 얻기위해 발포제를 함께 섭취하여 바륨과 공기의 이중조영촬영을 하기도 한다. 식도암, 위암 및 소화성궤양과 그밖에 다양한 병변의 진단에 효과적으로 사용된다. |

|---|---|---|---|
| 설명 | 방사선 조영제(방사선검사에서 다른 부위와 대조되는 아주 흰색을 띠는 물질)인 바륨을 섭취한 뒤, 촬영하는 작은창자의 기본적인 방사선 검사로서, 방법은 200~300mL의 바륨을 먹은뒤 바륨이 작은 창자를 통과하는 동안 정규적 간격으로 방사선 사진을 찍음. 일반적으로 2~3시간이 걸림. |

| aging | The gradual changes in the structure and function of humans and animals that occur with the passage of time, that do not result from disease or other gross accidents, and that eventually lead to the increased probability of death as the person or animal grows older. It does not apply to microorganisms. (12 Dec 1998) |
|---|---|
| aging, premature | Changes in the organism associated with senescence, occurring at an accelerated rate. (12 Dec 1998) |
| cell aging | The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences cell death via the process of apoptosis. (12 Dec 1998) |
| clonal aging | The deterioration in successive generations of a clone; thus paramecia and other simple forms, if allowed to reproduce asexually for a number of generations, invariably undergo deterioration, the characters of each group of descendants progressively departing from those of the original sexually produced ancestor. (05 Mar 2000) |
| skin aging | The process of aging due to changes in the structure and elasticity of the skin over time. It may be a part of physiological aging or it may be due to the effects of ultraviolet radiation, usually through exposure to sunlight. (12 Dec 1998) |
| erythrocyte aging | Senescence of the red blood cell. Lacking the organelles that make protein synthesis possible, the mature erythrocyte is incapable of self-repair, reproduction, and carrying out certain functions performed by other cells. This limits the average life span of an erythrocyte to 120 days. (12 Dec 1998) |
| aromatic series | All the compounds derived from benzene, or similar cyclic compounds that obey Huckel's rule, distinguished from those compounds that are acyclic or that contain rings that lack the conjugated double bond structure characteristic of benzene. (05 Mar 2000) |
| granulocytic series | <haematology> The cells in the several stages of development in the bone marrow leading to the mature granulocyte of the circulation, e.g., myeloblasts, different stages of the myelocyte, granulocytes. (05 Mar 2000) |
| myeloid series | The granulocytic and the erythrocytic series. (05 Mar 2000) |
| Hofmeister series | <chemistry> The series of cations Magnesium, Calcium, Sr2+, Ba2+, Li+, Na+, K+, Rb+, Cs+, and of anions citrate3-, tartrate2-, SO42-, acetate-, NO3-, CIO3-, I-, CNS- (among others). Each series is arranged in order of decreasing ability to: 1) precipitate the dispersed substance of lyophilic soltions; 2) "salt out" organic substances (e.g., aniline, ethyl acetate) from aqueous solutions; or 3) inhibit the swelling of gels. These effects, among other related ones, are ascribable to the abstraction and binding of water by these ions (i.e., hydration), which also decreases in the orders given, so that (in the monovalent cation series) Li+, with the smallest crystal radius, has the largest hydrated radius, and vice versa for Cs+. Synonym: lyotropic series. (05 Mar 2000) |
| homologous series | A series of organic compounds, the succeeding members of which differ from each other by the radical CH2 (as in the fatty series). (05 Mar 2000) |
| series | 1. A number of things or events standing or succeeding in order, and connected by a like relation; sequence; order; course; a succession of things; as, a continuous series of calamitous events. "During some years his life a series of triumphs." (Macaulay) 2. <biology> Any comprehensive group of animals or plants including several subordinate related groups. Sometimes a series includes several classes; sometimes only orders or families; in other cases only species. 3. <mathematics> An indefinite number of terms succeeding one another, each of which is derived from one or more of the preceding by a fixed law, called the law of the series; as, an arithmetical series; a geometrical series. Origin: L. Series, fr. Serere, sertum, to join or bind together; cf. Gr. To fasten, Skr. Sarit thread. Cf. Assert, Desert a solitude, Exert, Insert, Seraglio.

| small bowel series | Radiographic examination of the small intestine following the oral administration of contrast medium, usually barium sulfate. Compare: small bowel enema. (05 Mar 2000) |
| soil series | A group of soils having horizons similar in differentiating characteristics and arrangements in the soil profile, except for texture of the surface layer. (09 Oct 1997) |
| thrombocytic series | The cells of successive stages in thrombocytic (platelet) development in the bone marrow, e.g., thromboblasts, thrombocytes. (05 Mar 2000) |
