Seem to be alot of pharmacists in this thread... :?
Really where?Seem to be alot of pharmacists in this thread... :?
Of course it was a reaction to the venom. That's what venom does. However, it was not a hypersensitivity (ie allergic) reaction, since he did not have the typical symptoms of itching, hives, wheezing, hypotension, etc. As bad as it was, Rob's experience was rather typical for a severe Pokie envenomation.I'm sure there was an reaction to the venom. If someone is vulnerable to other venom then a bite from a T for them may be worse than someone who is not.
this is what I've heard as well. One of the owners of a herp store down here got bit by a pokie and had effects for years. Every once in a while he would get strange cramps around the bite area. Then nothing for months. does this type of venom cause lasting tissue damage?I hear you might feel more symptoms even up to a couple of weeks later so I would not be suprised if more cramps set in unexpectedly.
Yah that would really suck.Effects for years!?!Good grief.
Actually a lot. Not in humans, mind, but spider venom is quite well studied. By and large, excluding infections and the like, tarantula venom acts by blocking ion channels.And how many studys have there been?
Actually, not at all. The response from bee venom and shellfish is an allergic one - there is an immune system response to the venom which is treated as an antigen. In tarantula venom, the active molecules are short peptides - about 1 kDa in size. These are generally far too small to really trigger an immune response unless they have somehow gotten associated with a larger antigen.I'm sure there was an reaction to the venom. If someone is vulnerable to other venom then a bite from a T for them may be worse than someone who is not.
Ph.D. in Physical Biochemistry enough for you?Seem to be alot of pharmacists in this thread... :?
My best guess is that pretty much all his symptoms are a direct response of the venom acting on the nervous system - which is what is often the first reaction to ion channel blockers.Of course it was a reaction to the venom.

as far as venon gos my girlfriend she has two BS degrees, in biology and chemistry and looked some stuff up for me a little bit ago here is a link: http://www.arachnoboards.com/ab/showthread.php?t=140100&highlight=allergicOf course it was a reaction to the venom.

You are, of course, right... which is why I italicised the word 'generally' in my post above.as far as venon gos my girlfriend she has two BS degrees, in biology and chemistry and looked some stuff up for me a little bit ago here is a link: http://www.arachnoboards.com/ab/showthread.php?t=140100&highlight=allergic
I dont keep pokies right now or OBTs because I have roommates and I cant vouch for how smart they are so I dont keep Ts that there may be a savere reaction to. If it was just me no big deal but when you bring 6 guys all living in a house we get stupider
I totally agree with you. there are so many different ways allergies reach and effect.Still, the assumption that "he's allergic to bees, so that means he's more likely to be allergic to tarantulas" is wrong.
Although everyone thinks is right.You are, of course, right... which is why I italicised the word 'generally' in my post above.

LOL, at the beginning of this thread I posted pics of my Regalis that I got out and held for some pics before he molts. I got my Ornata out and decided that it is one T I wont be holding. It wasn't defensive per se, just SUPER FAST and skittish as a squirrel on crack. Both are at the 4" mark, nice to know the little ones can pack a heavy punchLuckily I'm feeling much better now so you won't have to listen to me whine, Nature Boy. LOL Remember though: I'm still one up on you...and I'm on my way to rehouse my Ornata now....it might just be two! LOL No way...
So bascially not very many studies have been done on humans and you are saying every one is going ot have the exact same reaction? I dont think so sorry. I was trying to say that some may be affected more by a bite than others.Actually a lot. Not in humans, mind, but spider venom is quite well studied. By and large, excluding infections and the like, tarantula venom acts by blocking ion channels.

These are generally far too small to really trigger an immune response unless they have somehow gotten associated with a larger antigen.
Bee venom is certainly acidic. From what I have gathered briefly, the magic ingredient in honeybee venom is 'Melittin' - also a relatively short peptide. The way this works is to directly induce inflammation - it is a powerful activator of phospholipase A2.Although everyone thinks is right.
You that are a Ph.D. in Physical Biochemistry, does the fact that the T uses its venom to help digesting its prey and the bee venom is for defense purposes have something to do with the reaction? (certainly have to do with the formula, bee's venom is based on acids from what i know)
correct me if i'm wrong![]()
Would this cause the blisters on his fingers too?Many spiders use a type of toxin called a sodium-channel antagonist. Sodium channels are important for nerve firing - the venom basically forces the channel open, and the nerve is then hard-wired 'ON' - meaning you get an overdose of nerve signal.
There are a few short term effects if these go bad - shaking, cramping, swelling, pain, heat sensations, sweating, shortness of breath, tachycardia (fast heart beat)... All basically ticked off in poor Rob.
I don't happen to have much in the way of information at my hand about P. regailis venom, but I'm guessing that from the sounds of it, it's a sodium channel inhibitor.
