Honey bee as apitoxin, carries several active components, the most abundant of which is melittin, and the most biologically active are enzymes, particularly phospholipase A2. Bee venom is under laboratory and clinical research for its potential properties and uses in reducing risks for adverse events from bee venom therapy, rheumatoid arthritis, and use as an immunotherapy for protection against allergies from insect stings. Bee venom products are marketed in many countries, but, as of 2018, there are no approved clinical uses for these products which carry various warnings for potential allergic reactions. With an increased number of honey bees in a specific
Dilute Russell's viper venom time Dilute Russell's viper venom time Dilute Russell's viper venom time (dRVVT) is a laboratory test often used for detection of lupus anticoagulant (LA). This "in vitro" diagnostic test is based on the ability of the venom of the Russell's viper to induce thrombosis. The venom contains some substances (RVV-V and RVV-X) which directly activate factor V and factor X, which turns prothrombin into thrombin in the presence of phospholipid and calcium. In the dRVVT assay, low, rate-limiting concentrations of both Russell's viper venom and phospholipid are used to give a standard clotting time of 23 to 27 seconds. This makes
