|---|---|
| true thirst | Thirst that can be satisfied by drinking water. (05 Mar 2000) |
| true vertebra | Any one of the cervical, thoracic, or lumbar vertebrae. Synonym: vertebra vera. (05 Mar 2000) |
| true vocal cord | One of Ferrein's cords; the sharp edge of a fold of mucous membrane overlying the vocal ligament and stretching along either wall of the larynx from the angle between the laminae of the thyroid cartilage to the vocal process of the arytenoid cartilage; the vocal folds are the agents concerned in voice production. Synonym: plica vocalis, chorda vocalis, labium vocale, true vocal cord, vocal cord, vocal shelf. (05 Mar 2000) |
| 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) |
| botulinus toxin | A potent neurotoxin from Clostridium botulinum. Synonym: botulin, botulismotoxin. (05 Mar 2000) |
| botulism toxin | <protein> A toxic byproduct of Clostridium Botulinum that is responsible for the food-borne illness known as botulism. (27 Sep 1997) |
| gamma toxin | <microbiology> Complex toxin (33.4 kD) produced by Staphylococcus aureus. Rabbit erythrocytes are particularly sensitive to lysis by the toxin, but the mechanism is unknown. (18 Nov 1997) |
| paralytic shellfish poisoning toxin carbamoylase | <enzyme> Hydrolytic enzyme from shellfish converts saxitoxin, neosaxitoxin, gonyautoxins 1 - 4 to the corresponding decarbamoyl toxins Registry number: EC 3.1.1.- Synonym: pcp toxin carbamoylase, saxitoxin carbamoylase (26 Jun 1999) |
