| 설명 | 미생물을 염색하는 방법 중의 하나. 1884년 덴마크의 의사 H.C.J. 그람(1853~ 1938)이 고안한 특수 염색법이다. 이 염색법을 사용하면 미생물은 양성균과 음성균의 2무리로 크게 나뉜다. 염색법은 균을 유리면에 바르고 가열 고정한다. 젠시안바이오렛, 크리스탈 바이오렛, 메틸바이오렛 등 파라로즈 아닐린계 색소의 어느 하나를 사용하여 우선 염색하고 이어서 루골액을 작용시킨 뒤, 에탄올 또는 아세톤으로 탈색한다. 이때 탈색되지 않고 보라색을 타나내는 것을 그람양성균이라 부르며, 포도알균-폐렴알균-사슬알균 등이 대표적인 예이다. 탈색되면 그람음성균이라 부르며, 대장균-녹농균 등이 있다. 최후에 사프라닌, 푹신 등 적색계의 색소액으로 후염색을 한다. 미생물의 감별에 중요한 염색법이며 염색성의 차이는 영양요구성, 화학요법제(항생물질 등)에 대한 감수성의 차이와도 관련되는 점이 많으므로 사용약제의 선택시에도 중요한 역할을 한다. 그람양성균과 음성균의 차이는 세균벽의 구조에 있는데, 양성균은 세포막의 바깥쪽 펩티드글리칸이라는 당단백질층의 두께가 20~80nm나 되고, 그램음성균의 펩티드글리칸 층은 2~3nm로 얇고, 다시 바깥쪽에 외막이라 부르는 층이 있다. |

| trypsin G-banding stain | <technique> A unique chromosome staining technique, used in human cytogenetics to identify individual chromosomes, which produces characteristic bands. It utilises acetic acid fixation, air drying, denaturing chromosomes mildly with proteolytic enzymes, salts, heat, detergents, or urea, and finally Giemsa stain; chromosome bands appear similar to those fluorochromed by Q-banding stain. Synonym: Giemsa chromosome banding stain. (05 Mar 2000) |

| a1-trypsin inhibitor | A glycoprotein that is the major protease inhibitor of human serum, is synthesised in the liver, and is genetically polymorphic due to the presence of over 20 alleles; individuals appropriately homozygous are deficient in a1-trypsin and are predisposed to pulmonary emphysema and juvenile hepatic cirrhosis because of alterations in the amino acid and sialic acid components of the glycoprotein. A1-Antitrypsin also inhibits thrombin. Synonym: a1-trypsin inhibitor, human a1-proteinase inhibitor. (05 Mar 2000) |

| Artemia trypsin-like proteinase | <enzyme> Cysteine proteinase involved in lipovitellin degradation Registry number: EC 3.4.22.- (26 Jun 1999) |
| crystallised trypsin | A purified preparation of the pancreatic enzyme; used as an adjunct to surgery for debridement of necrotic wounds and ulcers. (05 Mar 2000) |
| soybean trypsin inhibitor | Single polypeptide (21 kD, 181 amino acids) that forms a stable, stoichiometric, enzymically inactive complex with trypsin. (18 Nov 1997) |
| trypsin | <enzyme> Serine protease from the pancreas of vertebrates. Cleaves peptide bonds involving the amino groups of lysine or arginine. (18 Nov 1997) |
| trypsin inhibitor | A peptide hydrolyzed off trypsinogen under the catalytic influence of enteropeptidase, with trypsin produced as a result; so called because the peptide masks or inhibits the active site of the trypsin molecule, one of the polypeptides, from various sources (e.g., human and bovine colostrum, soybeans, egg white), that inhibit the action of trypsin. Compare: Bowman-Birk inhibitor. (05 Mar 2000) |
| trypsin inhibitor, bowman-birk soybean | <chemical> A low-molecular-weight protein (minimum molecular weight 8000) which has the ability to inhibit trypsin as well as chymotrypsin at independent binding sites. It is characterised by a high cystine content and the absence of glycine. Pharmacological action: trypsin inhibitors. (12 Dec 1998) |
| trypsin inhibitor, kazal pancreatic | <chemical> A pancreatic trypsin inhibitor common to all mammals. It is secreted with the zymogens into the pancreatic juice. It is a protein composed of 56 amino acid residues and is different in amino acid composition and physiological activity from the kunitz bovine pancreatic trypsin inhibitor (aprotinin). Chemical name: Trypsin inhibitor, pancreatic secretory (12 Dec 1998) |
| trypsin inhibitor, kunitz soybean | <chemical> A high-molecular-weight protein (approximately 22,500) containing 198 amino acid residues. It is a strong inhibitor of trypsin and human plasmin. Pharmacological action: trypsin inhibitors. Chemical name: Trypsin inhibitor, Kunitz soybean (12 Dec 1998) |
| trypsin inhibitors | Serine proteinase inhibitors which inhibit trypsin. They may be endogenous or exogenous compounds. (12 Dec 1998) |
| Abbott's stain | <technique> Spores are stained blue with alkaline methylene blue; bodies of the bacilli become pink with eosin counterstain. (05 Mar 2000) |
| aceto-orcein stain | <technique> A stain used for chromosomes in air-dried or squashed cytologic material. (05 Mar 2000) |
| acid-fast stain | <technique> A staining technique used to determine the cell wall property of a microorganism. After stained with dye such as hot carbolfuschin, an acid-fast organism, (for example Mycobacterium species) will retain the colour in its cell wall after being washed with acid-alcohol. (13 Nov 1997) |
| acid stain | <technique> A dye in which the anion is the coloured component of the dye molecule, e.g., sodium eosinate (eosin). (05 Mar 2000) |
| Ag-AS stain | <technique> A stain for the acid protein component of nucleolar regions which are active or which were transcriptionally active in the preceding interphase; uses silver nitrate, ammoniacal silver, and formalin. Synonym: Ag-AS stain. (05 Mar 2000) |
