Post Dangers of preservatives
CYTOTOXICITY AND MUTAGENICITY OF OPHTHALMIC SOLUTION PRESERVATIVES AND UVA RADIATION IN L5178Y CELLS

Four chemical preservatives commonly used in ophthalmic solutions were tested for their toxic and mutagenic potential in mouse lymphoma cells with and without exposure of the cells to ultraviolet A (UVA) radiation. The preservatives tested were benzalkonium chloride (BAK), chlorhexidine, thimerosal and ethylenediaminetetraacetic acid (EDTA). Cell survival and mutagenesis were measured using the L5178Y mouse lymphoma (TK+/-) system. Cells were exposed to varying amounts of preservatives for 1 h at 37o.C, and then aliquots were irradiated with UVA radiation (during the exposure to preservative). Cells were then assayed for survival, and for mutagenesis at the thymidine kinase (TK) locus. In concentrations commonly found in ophthalmic solutions, BAK, chlorhexidine, and thimerosal were toxic to cells, and thimerosal was slightly mutagenic. When cells were exposed to preservative and UVA radiation, chlorhexidine was mutagenic and the mutagenic activity of thimerosal was enhanced.

So the preservatives that those with contact lenses use (and probably OTC eye drops etc. also) not only are toxic to the cells in our eyes, but cause these cells to mutate. As a matter of fact, I recall that DH had an eye infection and his eyes got worse with the antibiotic the dr gave him. The dr put him on a different med and said he was allergic to the preservatives in the first one.

THIMEROSAL - better known as mercury, present still in some vaccines, controversy exists over the toxic effects of thimerosal in causing autism and other damage to children.

Quote:
Thiomersal is very toxic by inhalation, ingestion, and in contact with skin (EC hazard symbol T+), with a danger of cumulative effects. It is also very toxic to aquatic organisms and may cause long-term adverse effects in aquatic environments (EC hazard symbol N).[9] In the body, it is metabolized or degraded to ethylmercury (C2H5Hg+) and thiosalicylate.[3]

http://en.wikipedia.org/wiki/Thiomersal

We know what mercury is and how poisonous it is, but I wasn't sure what thiosalicylate was, except that it sounded like a relative of aspirin. Here's some info on it:

Thiosalicylate is an NSAID. (Non-steroidal anti-inflammatory drug)

Side Effects

Nausea/vomiting, dyspepsia, heartburn, hives, rash, angioedema, anaphylactic reactions, bronchospasm, rhinitis, prolonged bleeding time, thrombocytopenia, leukopenia, platelet dysfunction.,

Salicylates (Includes Sodium thiosalicylate) ↔ Reye's Syndrome
Severe Potential Hazard, High plausibility
Applies to: Influenza, Varicella-Zoster

The use of salicylates, primarily aspirin, in children with varicella infections or influenza-like illnesses has been associated with an increased risk of Reye's syndrome.

So if I understand this correctly, sodium thiosalicylate, one of the components of thimerosal, is being given to children via their vaccinations, yet parents are warned quite seriously not to give their children aspirin (salicylate) for fear of Reye's syndrome.... :huh

Quote:
Thimerosal remains in several vaccines and with the addition of the influenza vaccine now being recommended for infants, children are exposed to more thimerosal today than ever before.

Very good exposure piece Ruts, mercury is in all vac's today...

All part of the Eugenics program.
