Guest guest Posted September 2, 2008 Report Share Posted September 2, 2008 It seems to me that the unique atomic structure of radioisotopes is responsible. They decay, and emit energy during the process. This energy is what causes the damage. It is probably foolish for the biologists to think that they can target only one cell when by it's very physical nature, a radioisotope is unstable and by definition affects the field around them.

Guest guest Posted September 3, 2008 Report Share Posted September 3, 2008 No, that is not what this is about.. There is something else going on, something we don't as yet understand.. Cells that were NOT AT ALL DIRECTLY IRRADIATED die.. they call this the " bystander effect " and it cannot be the radiation, so much as the death of OTHER cells, that triggers it.

Guest guest Posted September 3, 2008 Report Share Posted September 3, 2008 Re: drawing parallels between radiation and stachybotrys/trichothecene survivors issues.. To give newcomers some IMPORTANT context, according to Ueno, Croft, and many others, a large number of mold effects are said to be " radiomimetic " because they are indistinguishable from radiation-induced cell and immune system damage. Similar kinds of damage are caused by chemotherapeutic drugs used in cancer treatment. (many of which are basically mycotoxins or structural analogs of mycotoxins) For example, I have a spectrum of GI issues that seem to mimic problems seen in radiation therapy or chemotherapy.. My gall bladder had issues seen in chemotherapy and radiation survivors.. My neuro issues mimic the often seen " chemo brain " cancer chemo survivors experience (and atom bomb survivors reported) This is an important connection- and CLUE, that is largely being overlooked..

Guest guest Posted September 3, 2008 Report Share Posted September 3, 2008 Live theres nothing being overlooked. did you read the article on urban air? do you think that maybe there are plenty of toxins/chemicals and even myco's involved there? dose,dose,dose and what happens to the immune system with toxic liver/system overload. plain and simple. many recover from chemotheropy unless they have some organ damage or immune problems and a moldy ass hospital and fungi gets in and takes over while their immune systems or even more suppressed. fungi doesn't mix well with other diseases, viruses,bacteria's,parisites,ect. it's not all about the myco's. --- In , LiveSimply <quackadillian@...> wrote: > > Re: drawing parallels between radiation and stachybotrys/trichothecene > survivors issues.. > > Quote Link to comment Share on other sites More sharing options...

I'm sorry, I don't really understand what you mean. I think that there is a strong connection between the effects of chemotherapy drugs like cyclosporin and some kinds of mycotoxicoses. That seems obvious, given the chemistry and the similarities in known effects. Also, some strains of stachybotrys contains a form of cyclosporin. This could in and of itself explain many deleterious effects.. But most importantly, we need to be very cautious, because the odds are that some WDB situations are very dangerous in many ways at the same time. Its like standing in a building containing a huge arsenal of ammunition, and its on fire. Any one of the many different kinds of bullets could kill you or wound you, and gettng hit by one in no way reduces the odds of your getting hit by another elsewhere. Its a random distribution that multiplies exponentially as moisture, food and time increases. So, I don't see how *anybody* could possibly reasonably lump all kinds of mold exposures together and say that " its this but not this " . That sounds like wishful thinking. In fact, that is exactly the term Dr. Kilburn used. Ive had a lot of discussions about neurotoxicity including one with Dr. Kaye Kilburn who is probably the leading expert on this issue, and he basically said that some kinds of mold neuro damage doesn't resolve, (however, some people manage to adapt to it, adapt to the losses) others don't. He has a LARGE body of statistical information. There are thousands of known toxic substances in the thousands of categorized fungi, and probably millions of fungi. that have not yet been named, placed into taxonomies, etc. Its important to realize this is a very complex problem. They keep discovering new fungi and new mycotoxins all the time. Some are very powerful. Others are benign. In any moldy building, there are thousands of different colonies many with more than one mold growing on top of each other. Just looking at cyclosporin, that is a powerful immunosuppressant. And it is a product of many different kinds of fungi, including some strains of stachybotrys.. And thats just one family of the literal army of toxins - water damaged building toxins.. . Especially see J Antibiot (Tokyo), 1993 Dec, 46(12), 1788 - 98 FR901459, a novel immunosuppressant isolated from Stachybotrys chartarum No . 19392 . Taxonomy of the producing organism, fermentation, isolation, physico-chemical properties and biological activities; Sakamoto K et al.; FR901459, a novel immunosuppressant, has been isolated from the fermentation broth of Stachybotrys chartarum No . 19392 . The molecular formula of FR901459 was determined as C62H111N11O13 . FR901459 was found to be a member of the cyclosporin family . However, it is structurally distinct from any other cyclosporins discovered so far, in that Leu is present at position 5 instead of Val . FR901459 was capable of prolonging the survival time of skin allografts in rats with one third the potency of cyclosporin A. http://www.journalarchive.jst.go.jp/jnlpdf.php?cdjournal=antibiotics1968 & cdvol=4\ 6 & noissue=12 & startpage=1788 & lang=en & from=jnltoc Mold Growth on Building Materials (122 pg PDF describing some of the better known metabolites that grow on common building materials) http://www.sbi.dk/indeklima/fugt-skimmel/mould-growth-on-building-materials/moul\ d-growth-on-building-materials/2006-01-12.6153316360 stachybotrys toxins. 1 Bruce B.

Guest guest Posted September 6, 2008 Report Share Posted September 6, 2008 Live, I think you took what I said out of text, I'm not sure of your point here, I think we all know that myco's can harm health. you need to understand there's a lot more to it than that. you might be waiting a long time if your thinking we well ever know and detect everything we were exposed to. toxic effects are toxic effects, total body load,TILT,ect. I prefer to look at the big picture and work with whats known which is actually quite a bit if you can read between the line and compare. if you dont think our immune system and matabolism cant also cause some major harm along what happens to us with these exposures, your wrong. , LiveSimply <quackadillian@...> wrote: > > On Wed, Sep 3, 2008 at 2:17 PM, who <jeaninem660@...> wrote: > > PS LIVE > > > > I'D BE MORE CAREFUL OF WHO YOU GET INFO.
