| 설명 | 혈장이나 체액 속에 존재하며 입자, 특히 세포나 미생물과 결합하여 강한 탐식성을 가진 큰포식세포 또는 과립 백혈구에 의한 포식작용을 쉽게 하여 주는 인자를 말한다. 포식세포 표면에는 항체의 Fc 분절수용체 또는 보체의 활성화 분절 C3b의 수용체가 존재하므로, ① 항체(특히 IgG와 IgM), ② C3b, ③ 항체도 보체도 아닌 것 등이 옵소닌으로서 작용한다. 1903년 라이츠 및 더글러스에 의해 발견되어 자연면역의 중요한 요소라고 생각되었다. 이 물질의 구조는 아직 알려지지 않았지만, 56℃에서 30분간 가열하면 작용이 없어지고 보체를 첨가하면 활성화된다. 특이성은 적고 여러 가지 세균에 작용한다. 백혈구-세균-혈청을 혼합하여 도말표본을 만들어 백혈구에 먹힌 세균 수를 세어 보면 옵소닌의 세기를 알 수 있다(옵소닌지수). |

| opsonation | A catering; a buying of provisions. Origin: L. Opsonatio. Source: Websters Dictionary (01 Mar 1998) |

| opsonic | Relating to opsonins or to their utilization. (05 Mar 2000) |
| opsonic index | A value that indicates the relative content of opsonin in the blood of a person with an infectious disease, as evaluated in vitro in comparison with presumably normal blood; the opsonic index is calculated from the following equation: phagocytic index of normal serum ÷ phagocytic index of test serum = 1 ÷ x, where x represents the opsonic index. (05 Mar 2000) |
| opsonin | <protein> Substance that binds to the surface of a particle and enhances the uptake of the particle by a phagocyte. Probably the most important in mammals derive from complement (C3b or C3bi) or immunoglobulins which are bound through the Fc receptor). (18 Nov 1997) |
| opsonisation | A process through which a cell or microbe is treated with opsonin to make it more vulnerable to being engulfed by a phagocyte. Often done simply by incubating particles (e.g. Zymosan) with fresh serum. (13 Oct 1997) |
| opsonization | The process by which bacteria are altered in such a manner that they are more readily and more efficiently engulfed by phagocytes. (05 Mar 2000) |
| opsonocytophagic | Pertaining to the increased efficiency of phagocytic activity of the leukocytes in blood that contains specific opsonin. Origin: opsonin + G. Kytos, a hollow (cell), + phago, to eat (05 Mar 2000) |
| opsonometry | Determination of the opsonic index or the opsonocytophagic activity. (05 Mar 2000) |
| opsonophilia | The condition in which bacteria readily unite with opsonins, thereby sensitizing them for more effective phagocytosis. Origin: opsonin + G. Phileo, to love (05 Mar 2000) |
| opsonophilic | Pertaining to, characterised by, or resulting in opsonophilia. (05 Mar 2000) |
