| 영문 | toxin | 한글 | 독소 |
|---|---|---|---|
| 설명 | 생물체가 만들어내는 독성과 항원성을 가진 물질. 독소를 적당한 동물에 주사하면 항체인 항독소가 생성되고, 이 항독소와 독소는 특이적으로 결합한다. 세균에 의한 단백분해산물로 맹독성을 발휘나는 것에 아민이 있으나, 이것에는 항원성이 없으므로 독소가 아니다. 일반적으로 중독증상을 발현하는데 일정한 시간이 걸리며, 동물에 따라 감수성이 다른 점이 독물과 다르다. 독소에는 생물체 안에 만들어져 남아 있다가 생물체가 파괴되었을 때 독성을 갖는 내독소(endotoxins)와 생물체가 주변으로 물질을 분비하는 외독소(exotoxins)가 있다. 독소를 내는 생물체에 따라 세균성 독소 외에 동물성 독소 및 식물성 독소가 있다. 동물성 독소는 대부분 독선에서 분비되며, 뱀-전갈-거미-벌 등이 대표적인 것이다. 식물성 독소로는 리신(ricin)-아브린(abrin)-로비닌(robinin)-크로틴(crotin) 등이 있다. 세균은 인체에 영향을 미쳐 디프테리아-파상풍-성홍열-가스괴저 등을 일으키고, 또 어떤 세균과 버섯류는 생장할 때 독소를 분비, 이것을 먹으면 보툴리누스 중독-맥각 중독 등을 일으킨다. 그 밖에 물고기에도 독성을 가진 것이 있다. 인체에는 독소가 들어왔을 때 그와 결합하여 독성을 해독시키는 항독소가 혈청-림프액 등에 생긴다. |

| extracellular toxin | <protein> Toxin released from gram-positive and gram-negative bacteria as opposed to endotoxins that form part of the cell wall. Examples are cholera, pertussis and diphtheria toxins. Usually specific and highly toxic. (18 Nov 1997) |

| extracellular | Outside a cell or cells. (18 Nov 1997) |
|---|---|
| extracellular enzyme | <enzyme> An enzyme performing its functions outside a cell; e.g., the various digestive enzyme's. Synonym: exoenzyme, lyoenzyme. (05 Mar 2000) |
| extracellular fluid | The fluid found outside of the cell or cells and between the cells in a tissue. (09 Oct 1997) |
| extracellular fluid volume | The fraction of body wate rnot in cells; about 25% of body weight. It consists of plasma water (4.5% of body weight), water between cells (interstitial water-lymph, 11.5% of body weight), water in dense bone and connective tissue (7.5% of body weight) and water secretions.See transcellular water, about 1.5% of body weight.. (05 Mar 2000) |
| extracellular matrix | Any material produced by cells and secreted into the surrounding medium, but usually applied to the noncellular portion of animal tissues. The ecm of connective tissue is particularly extensive and the properties of the ecm determine the properties of the tissue. In broad terms there are three major components: fibrous elements particularly collagen, elastin or reticulin), link proteins (e.g. Fibronectin, laminin) and space filling molecules (usually glycosaminoglycans). The matrix may be mineralised to resist compression (as in bone) or dominated by tension resisting fibres (as in tendon). The basal lamina of epithelial cells is another commonly encountered ecm. Although ecm is produced by cells, it has recently become clear that the ecm can influence the behaviour of cells quite markedly, an important factor to consider when growing cells in vitro: removing cells from their normal environment can have far reaching effects. (18 Nov 1997) |
| extracellular matrix proteins | Macromolecular organic compounds that contain carbon, hydrogen, oxygen, nitrogen, and usually, sulfur. These macromolecules (proteins) form an intricate meshwork in which cells are embedded to construct tissues. Variations in the relative types of macromolecules and their organization determine the type of extracellular matrix, each adapted to the functional requirements of the tissue. The two main classes of macromolecules that form the extracellular matrix are: glycosaminoglycans, usually linked to proteins (proteoglycans), and fibrous proteins (e.g., collagen, elastin, fibronectins and laminin). (12 Dec 1998) |
| extracellular space | Interstitial space between cells, occupied by fluid as well as amorphous and fibrous substances. (12 Dec 1998) |
| Yarrowia lipolytica alkaline extracellular protease | <enzyme> First secreted as precursor Registry number: EC 3.4.21.- Synonym: alkaline extracellular protease, yarrowia lipolytica, yl-ae protease (26 Jun 1999) |
| animal toxin | <pharmacology> Any poisonous substance (including but not limited to venom) produced by an animal. (11 May 1997) |
| anthrax toxin | A culture filtrate of Bacillus anthracis containing an exotoxin with at least three different antigenically distinct components: oedema factor, lethal factor, and protective antigen. Synonym: Bacillus anthracis toxin. (05 Mar 2000) |
| Bacillus anthracis toxin | A culture filtrate of Bacillus anthracis containing an exotoxin with at least three different antigenically distinct components: oedema factor, lethal factor, and protective antigen. Synonym: Bacillus anthracis toxin. (05 Mar 2000) |
| bacterial toxin | Any intracellular or extracellular toxin formed in or elaborated by bacterial cells. (05 Mar 2000) |
| bee toxin | The toxin delivered by a bee sting; contains three active principles: biogenic amines, active peptides, and certain hydrolytic enzymes. (05 Mar 2000) |
| botulinum toxin | <protein> Neurotoxin (50 kD, 7 distinct serotypes) produced by certain strains of Clostridium botulinum. The bacterium produces the toxin as a complex with a haemagglutinin that prevents toxin inactivation in the gut. Proteolysis in the body results in cleavage into two fragments A and B. B binds to gangliosides and may stimulate the endocytosis of fragment A. See: synaptobrevin, tetanus toxin. (18 Nov 1997) |
| botulinum toxin type a | <chemical> A neurotoxin produced by clostridium botulinum. When consumed in contaminated food it can cause paralysis and death. In its purified form, it has been used in the treatment of blepharospasm and strabismus. Pharmacological action: neuromuscular agents. (12 Dec 1998) |
