| 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) |
