Heavy Metal Toxicity
|
disclaimer |
Low Metallothionein is from either a genetic condition or from
exposure to toxins and can be the root cause of diabetes, oxidative
stress, and autoimmune disease. The reports below show that
it can also cause parasite growth. Treating
diabetes, immune disorders, parasites and oxidative stress when
caused by heavy metal toxicity nullifies the effectiveness of
their treatments. Drugs such as insulin for a diabetic may be
an essential drug however if one has metal toxicity it is less
effective, thus requiring greater doses than may be required
if heavy metals are removed. One of the first steps in restoring
health must be to evaluate and treat heavy metal toxicity.

1. "...Some
experts on auto-immune disorders,...believe that one of the underlying
causes of the explosion in auto-immune diseases is due to pesticides
used as common practice in agriculture. There is also
much evidence that all chronic health disorders, including auto-immune
can be triggered by the accumulation of heavy metals in the body,
especially those involving the nerves such as M.S, ALS, Motor-neuron
disease. " (1)

2. "Candida
- Another effective way to combat candida is using zinc therapy.
Candida is killed by metallothionein (MT) proteins which are normally
in high concentration in intestinal mucosa. MT is induced by zinc.
Many persons with candida are low zinc and low MT persons. They
usually exhibit low zinc in plasma, serum, or packed cells, but
high zinc in hair. You can expect chronic candida problems until
zinc is normalized. In a sense, zinc can be an effective weapon
in your anti-candida arsenal. Typical anti-candida therapies (including
dietary restrictions) can manage the problem for a while.......
Maintenance supplementation with zinc (after these interventions)
can permanently fix the problem, in many cases, without the need
to continue dietary vigilance. (Feb 5, 2003)...Metallothionein levels
are reported to be related to Attention Deficit Disorders"

4. ""Scientists
have discovered the ability of a protein which helps the brain heal
itself...Research performed over the past two years by Mr Chung,
a PhD student in the NeuroRepair Group at the University of Tasmania,
has identified the ability of a family of naturally-occurring proteins,
named metallothioneins, to influence brain healing
following injury...The first would be by boosting the amount of
metallothionein produced by the brain following a traumatic event...“To
do that we’d need to discover the on-off switch that allows
the body to produce the protein naturally, which is something that
we are investigating right now” he said. “The second
possibility would be to make metallothionein artificially, which
is a straightforward process, and inject it directly into patients.”

5. Metallothionein
and Autism. "... metallothionein (MT) proteins, their
central role in autism, and provides more than 100 references. The
Pfeiffer Treatment Center recently discovered that (a) most autism-spectrum
patients exhibit evidence of an MT dysfunction, and (b) many of
the classic features of autism can be explained by this dysfunction.
We believe that autism results from a genetic defect in MT functioning
followed by an environmental insult. A metallothionein theory of
autism is presented along with discussion of treatment opportunities."

6. "
People with health issues have one thing in common: Almost all of
them have some degree of digestive failure...This
is what the body faces. It needs to make thousands of enzymes and
other necessary chemicals, but does not have the raw materials.
And it cannot get them from food because the digestion is not efficient
enough. Even supplementation of stomach acid and enzymes usually
does not enable the body to make enough free amino acids. So necessary
materials cannot be produced. One compound that is necessary for
health in a polluted world is metallothionein...The
body uses metallothionein to carry away mercury and other toxic
metals. But the body cannot make this material if there is a shortage
of free amino acids. At http://www.doctorvickery.com
there are more charts showing toxic metal removal using a product
called Platinum Plus Essential Amino Acids. Each patient was also
required to take a multivitamin-mineral product and 1/4 teaspoon
of natural salt ( such as Real Salt or Celtic salt) in water daily.
Those who did not take in enough salt failed to make good progress...The
body also needs free amino acids to make neurotransmitters. I am
hearing reports from people recovering from depression while using
amino acids...The immune system also needs free amino acids...Fibromyalgia
is another condition where there is an amino acid deficiency. Other
conditions that involve a lack of free amino acids include skin
wrinkling, thinning of hair, weak fingernails along with more serious
conditions such as digestive failure, irritable bowel, chronic fatigue,
spinal disk degeneration, joint degeneration, osteoporosis, pain
and stiffness, infections, and stress to every tissue in the body...Amino
acids are food. They are not medication and they do not "cure"
anything. They do not make anything happen. They simply provide
raw materials to the body. When combined with vitamins, minerals
(especially sulfur) and essential fatty acids, they just help people
move toward health." (5) The source
article contains a lot of important information including MT's relationship
to the immune system.

7. "...MT
may therefore represent a "danger signal"; modifying the
character of the immune response when cells sense cellular stress.
Elevated metallothionein produced in the context of exposure to
environmental toxicants, or as a result of chronic inflammatory
disease, may alter the normal chemotactic responses that regulate
leukocyte trafficking. Thus, MT synthesis may represent an important
factor in immunomodulation that is associated with autoimmune disease
and toxicant exposure." (6)

8. Low
MT causes Liver problems "Methionine: Methionine
levels are a major determinant in the liver's concentration of sulphur-containing
compounds, such as glutathione and cysteine. As methionine is the
precursor for the manufacture of cysteine in the body, extra supplementation
of this critical amino acid should increase available cysteine.
Animal studies have shown that methionine protects rats from the
toxic effects of lead and mercury. Chelating agents such as DMSA
(dimercapto succinic acid) and DMPS (dimercapto-propane sulfonic
acid) bind to cysteine for excretion. L-cysteine bound to mercury
(L-penicillamine, N-acetyl-L-cysteine, DMSA and glutathione complexed
with methylmercury) resembles the L-methionine molecule and can
cross the blood brain barrier. L-methionine inhibits the transport
of these complexes into the brain. Methionine increases the bioavailability
of glutathione. Most of the cysteine required for the resynthesis
of glutathione must originate from methionine and not from cysteine
generated by the catabolism of glutathione. Patients taking only
D-L-methionine increased mercury excretion in the urine by 60% over
the excretion rate before taking the methionine. Lead excretion
was also increased. The L-form is rapidly metabolized by the liver
and does not offer a sustained antioxidant level. Over half of the
D-form is slowly metabolized by the same pathways as excess L, and
acts identical to L as an antioxidant. The benefit of the D-L form
of methionine is the D form provides sustained blood levels allowing
he L-form to be converted to other sulfur antioxidants. Babies need
22 mg/Kg body weight of methionine on a daily basis while adults
need 10 mg/Kg of body weight daily."(8)" (7)

9. "Exposure
to heavy metals is a common phenomenon due to their environmental
pervasiveness. Metal intoxication particularly neurotoxicity, genotoxicity,
or carcinogenicity is widely known. This review summarizes our current
understanding about the mechanism by which metalloids or heavy metals
(particularly arsenic, lead, cadmium and mercury) induce their toxic
effects. The unifying factor in determining toxicity
and carcinogenicity for all these metals is the generation of reactive
oxygen and nitrogen species. The toxic manifestations
of these metals are caused primarily due to imbalance
between pro-oxidant and antioxidant homeostasis which
is termed as oxidative stress" (9) This
report has significant importance in treating oxidative stress and
oxidation factors. It validates my claim that the first step to
repair ones health is to find and eliminate the root causes. Treating
diabetes, immune disorders, and oxidative stress when caused by
heavy metal toxicity, parasites or any root cause nullifies the
effectiveness of their treatments.

10."The
liver is the major detoxification center of the body. It acts as
an “in-line” filter for the removal of foreign substances
and wastes from the blood. Toxins that are cleared by the liver
include alcohol, solvents, formaldehyde, pesticides, herbicides
and food additives. Despite varying chemical toxicity, the liver
has the function of reducing toxins into compounds that the body
can safely handle and remove through the kidneys (as urine), skin
(as sweat), lungs (as expelled air) and bowels (as feces). Optimal
liver function is therefore essential for good health. The symptoms
of heavy metal poisoning in the liver include psychological and
neurological symptoms such as depression, headache, mental confusion,
mental illness, abnormal nerve reflexes and tingling in the hands.
The solution is to take compounds that support the liver's detoxification
mechanism. Such compounds include milk thistle extract, choline,
methionine , and antioxidants." (12)
11. "Metallothionein
protein plays an important role in regulation of zinc and copper
levels in the blood, detoxification of heavy metals as they enter
the body, development and continued functioning of the immune system,
development and pruning of brain cells, (neurons), prevention of
yeast overgrowth in the intestines, production of enzymes that break
down casein and gluten, production of hydrochloric acid by stomach
cells, taste and texture discrimination by the tongue, behavior
control and development of memory and social skills." (13)

12. "Metallothionein
(MT) plays a role in fundamental cellular processes such as proliferation,
apoptosis and differentiation. We examined MT expression in women
with invasive breast ductal carcinoma who underwent mastectomy/lumpectomy
without neo-adjuvant treatment. We showed that MT was
over-expressed in 87.9% of breast cancer tissues examined"
(14) MT shown to relate to breast
cancer

13. "Grape
seed procyanidins
inhibit the expression of metallothione in genes in human HepG2
cells...Our findings demonstrate that metallothionein genes are
direct targets of procyanidins action, both in vivo and in vitro,
in hepatic cells. Thus, this study will help to elucidate the mechanisms
by which procyanidin exert their beneficial actions." (15)
12. "New
insights into generalized hepatoprotective effects of oleanolic
acid: key roles of metallothionein and Nrf2 induction. OA treatment
also increased the expression of genes related to cell proliferation
and suppressed the expression of several cytochrome P450 genes possibly
to switch cellular metabolic energy to an acute-phase response.
Hepatic MT protein was increased 60- and 15-fold in mice and rats,
respectively, together with a 30% increase in mouse liver zinc.
These gene expression changes, particularly the dramatic induction
of MT and the Nrf2 signaling, occur with hepatoprotection doses
of OA, and likely are important in the generalized protective effects
of OA against hepatotoxicants." (16)

12. "Podocyte-specific
overexpression of the antioxidant metallothionein reduces diabetic
nephropathy." (17) Means high expression
of metallothionein reduces diabetic nephropathy, thus low MT relates
to nephropathy.

| 1. Zinc
and Selenium: Research shows that zinc does not chelate
with copper but rather increases Metallothionein in the body
and it is Metallothionein that carries copper out of the body.
See Selenium for
information that indicates taking Zinc is not enough. Zinc
may already be in sufficient levels in the body and is being
blocked. Low Selenium may impede the effectiveness of Zinc
and taking Selenium may unblock Zinc thus aiding the healing
and increase of Metallothionein. As I find more research on
this I will include it. (8) |

Metal & Mercury Chelator...heavy metals in the body poses
a significant risk to life and health, including anemia, memory
loss, cancer, depression, male infertility, gingivitis, and
maybe even multiple sclerosis and Alzheimer's disease...DMSA
is a potent chelator of mercury...Long-term exposure to low
levels of lead...a number of disorders and diseases, including
learning and behavior problems, cardiovascular and kidney
diseases, decreased fertility, hypertension and cancer...
Caution: DMSA should be taken under the supervision of a physician
trained in chelation therapy. Not for use by pregnant or lactating
women or by children, unless under supervision of a physician.
If nausea, vomiting or rash occurs, decrease dosage or discontinue
use.(11)
