Hva slags gift er det i knapper?

Så linken over hadde 10 sider med kommentarer så jeg prøver meg her istedenfor.

Har hørt historiene om giften og knappene, men gjelder dette alle knapper?

 

Med konstant småsår på hendene og unger i huset så må jeg jo ta noen forhåndsregler. Liten vits å dyrke knapper om de er så hinnsides farlige og unga vet en jo kommer til å tukle med karrene når far ikke passer på.

Har hørt de skiller en slags nervegift og kan være ganske farligt. Men det er forskjellig fra knapp til knapp. Så de har forskjellig mengder. Så bruk alltid hansker når du holder på med knapper og vær obs på sår osv.

 

Har lagt merke til at det svir i hendene mine i kontakt med noen korall typer, men så tøff som jeg er så bruker jeg ikke hansker når jeg romsterer i saltvannkaret. Bruker da bare hansker når jeg fragger de opp. :P

 

Så når du fragger så bør du låse ungen,husdyrene i eget rom så kan du holde på i fred og ro. Ellers kan hunden din ligge der og er grønn eller blå i ansiktet. :mad:

Palytoxin in zoantids:

 

Some zoanthids contain the highly toxic substance palytoxin. Palytoxin is one of the most toxic organic substances in the world, but there is an ongoing debate over the concentration of this toxin in these animals.[citation needed] However, even in small quantities, the toxin can be fatal should it be ingested or enter the blood stream. If delivered immediately, vasodilators injected into the ventricle of the heart can act as an antidote.[1]

In order for this toxin to be dangerous to humans, the average aquarist would need to ingest the zoanthid in sufficient quantities, or brush a recent cut over it. Average handling, propagation and aquarium maintenance is unlikely to pose any danger beyond a localized skin reaction.[citation needed] A 2010 study found toxic zoanthids in three Washington D.C. area aquarium stores.[15]

Contrary to common belief, palytoxin can be absorbed through intact skin.[16] The danger of acute poisoning from venomous zoanthids is quite real. An aquarist was poisoned through skin injuries on fingers by a Parazoanthus species, but recovered after 3 days. His zoanthid was found to contain 2-3 milligram of palytoxin per gram.[17] For comparison, the intravenous LD50 dose of palytoxin for a grown man is less than 8 microgram. Thus each gram of the offending zoanthid contained enough venom to kill at least 125 grown men.

Palytoxin is a tumor promoter, and is being studied in relation to signaling pathways in skin cancer genesis.[18]

[edit]Diet

 

Zoanthids feed both by photosynthesis, aided by the zooxanthellae they contain, and by capturing plankton and particulate matter. Although photosynthesis aids in their nutrition, even species that do not actively capture plankton cannot live through photosynthesis alone.[19] Zoanthids can eat meaty foods, such as lancefish, brine shrimp, krill and bloodworms.

Stresstestet palytoxin i vinter, anbefales ikke:P Er vel 11 mikrogram som er dødsdosen til mennesker. Er et veldig komplekst giftstoff som sykehuset ikke har noen kur for. Da jeg ble lagt inn ble jeg hjertemonitorert og tok en nyredialyse.
