Get the facts http://www.crazyperson.to/IDon'tUnderstandScience.html If by fact you mean the crazy rambling of people who don't understand science, can't form a cogent argument, and address studies that prove them wrong.... then yes there are lots of facts there. Eric LOL. Dr. Boyd Haley, Professor and Chair, Dept. of Chemistry, University of Kentucky and one of the world's leading authorities on mercury toxicity. That would be the Boyd Haley that told me that ethylmercury could be considered to be the same chemical as methylmercury. Which the study I posted now clearly refutes. It would also be the Boyd Haley that told me that the proportion of the molecular weight of a compound made up by one of the elements had something to do with transferring the properties of the element to the compound. Which any HS chemistry book clearly refutes. In other words, that would be the Boyd Haley who probably knew something about chemistry once (he did get an academic job in the area) but has either forgotten it all or is prepared to lie. And let's not forget that that would be the Boyd Haley who called autism "mad child disease". Which he never apologized for. I think that the biological case against Thimerosal is so dramatically overwhelming anymore that only a very foolish or a very dishonest person with the credentials to understand this research would say that Thimerosal wasn't most likely the cause of autism.---Interview of Dr. Boyd E. Haley by Teri Small: http://www.whale.to/v/haley_q.html Joe Mercola disagrees with him. Is that good or bad? |

Monkeys were exposed to MeHg (via oral gavage) or vaccines containing thimerosal (via intramuscular injection) at birth and 1, 2, and 3 weeks of age. Total blood Hg levels were determined 2, 4, and 7 days after each exposure. Total and inorganic brain Hg levels were assessed 2, 4, 7, or 28 days after the last exposure. The initial and terminal half-life of Hg in blood after thimerosal exposure was 2.1 and 8.6 days, respectively, which are significantly shorter than the elimination half-life of Hg after MeHg exposure at 21.5 days. Brain concentrations of total Hg were significantly lower by approximately 3-fold for the thimerosal-exposed monkeys when compared with the MeHg infants, whereas the average brain-to-blood concentration ratio was slightly higher for the thimerosal-exposed monkeys (3.5 ± 0.5 vs. 2.5 ± 0.3). A higher percentage of the total Hg in the brain was in the form of inorganic Hg for the thimerosal-exposed monkeys (34% vs. 7%).

Haley by Teri Small: http://www.whale.to/v/haley_q.html It is truly sad when a person of Haley's education and experience tries to support his theories by claiming that the fact that the one mercury atom in thimerosal comprising 49% of the molecular weight actually has some form of meaning. Further, Haley was recently toss on his tushy by a district court judge who found that his opinions do not meet the Daubert standard. While we are considering that level of mercury, we must consider that much more than that is released every time a single fluorescent bulb is replaced in a room. Everyone should rush to their office manager and complain. |

It gives me a sense of stability to know that I can go away for a few months and come back to the same old junk that was being posted when I left. It's unclear to me how the pro-vaccine group could use this information to their advantage. Here's what I see when I read the above info. Brain concentrations of total Hg were significantly lower by approximately 3-fold for the thimerosal-exposed monkeys when compared with the MeHg infants, whereas the average brain-to-blood concentration ratio was slightly higher for the thimerosal-exposed monkeys (3.5 ± 0.5 vs. 2.5 ± 0.3). OK, so they were lower. How would those infants otherwise be exposed to MeHg in the real world? The point is that this comparison is ridiculous. The fact that brain concentrations were lower in the thimerosal group means nothing. They're STILL HIGHER if you compare them to a group that received no mercury at all. Why in the world would this stuy compare a thimerosal group with a MeHg group when their shouldn't be any MeHg groups in the real world? Shouldn't the point of the study be to compare real world scenarios? A higher percentage of the total Hg in the brain was in the form of inorganic Hg for the thimerosal-exposed monkeys (34% vs. 7%). hhhmmmm... there's that mercury in the brain again. Funny how that paragraph mentions the half life of mercury in the blood but neglects to mention it in the brain. Could that be because the brain has a much harder time getting rid of the mercury than the blood? Also, shouldn't the fact that the mercury in the brains of the thimerosal group was mostly inorganic be a concern? I thought you pro-vaccine guys were constantly saying that the end Hg product from thimerosal was all organic. The results indicate that MeHg is not a suitable reference for risk assessment from exposure to thimerosal-derived Hg. Knowledge of the toxicokinetics and developmental toxicity of thimerosal is needed to afford a meaningful assessment of the developmental effects of thimerosal-containing vaccines. So, basically, this last piece is saying exactly what it *should* say... this study is meaningless, since more study is needed for "a meaningful assessment." Leave it to the pro-vaccine side to disagree with that and try to use it to prove some sort of point. You should pick apart your studies a little better before posting them. Max. |
