The effect of changes in temperature on the toxicity of jellyfish, Crambionella orsini

The aim of this study was to evaluate the effect of temperature changes to reduce toxicity of jellyfish Crambionellaorsini venom. Venom extraction was done according to Bloom method. Sonication was used to break the wall of nematocysts capsule and then the resulting solution was centrifuged. To evaluate the effect of temperature on the venom, it was heated at different temperatures and then injected into sori mice. After catching jellyfish, Crambionellaorsini from Arvand stream estuary edges of umbrellas and tentacles of jellyfish were separated and kept in water LD_50 of toxins were calculated by Jung and Choi method and statistical analysis to obtain minimal lethal dose of poison done by Excel 2007. The results showed that the venom of jellyfish Crambionellaorsini, like venom of other animals is, based on a protein and that is sensitive to heat. This venom is disabled and lose their structure at 48 °C and its minimum lethal dose is 0.5 ml.
