| carbutamide | <chemical> A sulfonylurea antidiabetic agent with similar actions and uses to chlorpropamide. Pharmacological action: hypoglycaemic agents. Chemical name: Benzenesulfonamide, 4-amino-N-((butylamino)carbonyl)- (12 Dec 1998) |
|---|---|
| carbuterol hydrochloride | [5-[2-(tert-Butylamino)-1-hydroxyethyl]-2-hydro xyphenyl]urea monohydrochloride;a sympathomimetic drug with bronchodilatory activity. (05 Mar 2000) |
| carcass | The body of a dead animal; in reference to animals used for human food, the body after the hide, head, tail, extremities, and viscera have been removed. Origin: F. Carcasse, fr. It. Carcassa (05 Mar 2000) |
| carcinaemia | Debilitation and emaciation caused by advanced-stage cancer. (09 Oct 1997) |
| carcinine synthetase | <enzyme> Requires ATP, beta-alanine, histamine, magnesium and dithiothreitol; forms beta-alanylhistamine(=carcinine) Registry number: EC 6.3.2.- (26 Jun 1999) |
| carcino- | Cancer; crab. Origin: G. Karkinos, crab, cancer (05 Mar 2000) |
| carcinoembryonic | Relating to a carcinoma-associated substance present in embryonic tissue, as a carcinoembryonic antigen. (05 Mar 2000) |
| carcinoembryonic antigen | <tumour marker> Antigen found in blood of patients suffering from cancer of colon and some other diseases, that is otherwise normally found in foetal gut tissue. (19 Jan 1998) |
| carcinogen | <chemistry, oncology> An agent capable of initiating development of malignant tumours. May be a chemical, a form of electromagnetic radiation or an inert solid body. (19 Jan 1998) |
| carcinogenesis | <cell biology, oncology> The generation of cancer from normal cells, correctly the formation of a carcinoma from epithelial cells, but often used synonymously with transformation, tumourigenesis. (19 Jan 1998) |
| carcinogenic | Producing carcinoma. Origin: Gr. Gennan = to produce (18 Nov 1997) |
| carcinogenicity tests | Tests to experimentally measure the tumour-producing/cancer cell-producing potency of an agent by administering the agent (e.g., benzanthracenes) and observing the quantity of tumours or the cell transformation developed over a given period of time. The carcinogenicity value is usually measured as milligrams of agent administered per tumour developed. Though this test differs from the DNA-repair and bacterial microsome mutagenicity tests, researchers often attempt to correlate the finding of carcinogenicity values and mutagenicity values. (12 Dec 1998) |
| carcinogens | Substances that increase the risk of neoplasms in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included. (12 Dec 1998) |
| carcinogens, environmental | Carcinogenic substances that are found in the environment. (12 Dec 1998) |
| carcinoid | <oncology, tumour> Intestinal tumour arising from specialised cells with paracrine functions (APUD cells). The primary tumour is commonly in the appendix, where it is clinically benign, hepatic secondaries may release large amounts of vasoactive amines such as serotonin to the systemic circulation. Synonym: argentaffinoma. (19 Jan 1998) |
