| bee toxin | The toxin delivered by a bee sting; contains three active principles: biogenic amines, active peptides, and certain hydrolytic enzymes. (05 Mar 2000) |
| bee venoms | Venoms obtained from apis mellifera (honey bee) and related species. They contain various enzymes, polypeptide toxins, and other substances, some of which are allergenic or immunogenic or both. These venoms were formerly used in rheumatism to stimulate the pituitary-adrenal system. (12 Dec 1998) |

| black widow spider venom | Potent neurotoxin that induces catastrophic release of acetylcholine from presynaptic terminals of cholinergic chemical synapses. (18 Nov 1997) |
| venom | <chemical> A toxic secretion in animals that is actively delivered to the target organism, either to paralyse or incapacitate or else to cause pain as a defence mechanism. Commonly include protein and peptide toxins. (12 Jan 1998) |
| venom haemolysis | That caused by haemolytic material in the venom of various species of snakes or other venomous animals. (05 Mar 2000) |
| Russell's viper venom | A venom used as a coagulant in the arrest of haemorrhage from accessible sites in haemophilia. (05 Mar 2000) |
| Russell's viper venom clotting time | A clotting time determination performed on citrated platelet-poor plasma using Russell's viper venom as an activating agent. This allows activation of factor X directly without the need for other coagulation factors and is used to confirm factor X defects. See: Stypven time test. (05 Mar 2000) |
| cobra venom cofactor | <enzyme> A glycine-rich, heat-labile beta-glycoprotein found in blood. It is a proactivator of complement 3 in the alternate pathway of complement activation. Factor b is converted by factor d to c3 convertase. Registry number: EC 3.4.21.47 (12 Dec 1998) |
| cobra venom factor | A component of cobra venom that renders C3 proactivator (properdin factor B) susceptible to factor D of the properdin system, leading to activation of C3 and other components of complement and lysis of unsensitised erythrocytes. (05 Mar 2000) |
| crotalid venom | <herpetology> Venoms from snakes of the subfamily crotalinae or pit vipers, found mostly in the americas. They include the rattlesnake, cottonmouth, fer-de-lance, bushmaster, and american copperhead. Their venoms contain nontoxic proteins, cardio-, haemo-, cyto-, and neurotoxins, and many enzymes, especially phospholipases a. Many of the toxins have been characterised. (12 Dec 1998) |
| direct lytic factor of cobra venom | A polypeptide of 62 residues; action on cells is similar to that of melittin in that it promotes disruption of membranes; used as an investigational antirheumatic agent. Synonym: cobra toxin, direct lytic factor of cobra venom. (05 Mar 2000) |
| kokoi venom | A potent neurotoxin found in the frog Phyllobates bicolor; it is a nonprotein compound with a molecular weight of approximately 400, and is lethal in microgram quantities. (05 Mar 2000) |
