atherosclerosis / iron

As in most of your posts involving iron, it must be noted
that it would be very surprising if iron was not involved in
many of the bodies processes. Iron is absolutely critical
for proper and optimal health, in addition to it's well
known role in transporting oxygen to cells in the blood,
there are several other critical roles it plays. Here is
one: " Antioxidant and beneficial pro-oxidant functions

Catalase and peroxidases are heme-containing enzymes that
protect cells against the accumulation of hydrogen
peroxide, a potentially converts hydrogen peroxide to to
water and oxygen. As part of the immune response, some
white blood cells engulf bacteria and expose them to ROS
in order to kill them. The synthesis of one such ROS,
hypochlorous acid, by neutrophils is catalyzed by the heme-
containing enzyme myeloperoxidase (3, 4)."

As time goes on, we will explore other roles iron plays in
proper and optimal health. It is well and good that you
bring the value of iron to our attention and we look forward
to a joint effort in education in this regard.

Direct Detection and Quantification of Transition Metal Ions
in Human Atherosclerotic Plaques: Evidence for the Presence
of Elevated Levels of Iron and Copper.

Stadler N, Lindner RA, Davies MJ.

The Heart Research Institute, Sydney, Australia.

OBJECTIVE: The involvement of transition metals in
atherosclerosis is controversial. Some epidemiological
studies have reported a relationship between iron (Fe) and
cardiovascular disease, whereas others have not.
Experimental studies have reported elevated levels of iron
and copper (Cu) in diseased human arteries but have often
used methods that release metal ions from proteins. METHODS
AND RESULTS: In this study, we have used the minimally
invasive technique of electron paramagnetic resonance (EPR)
spectroscopy and inductively coupled plasma mass
spectroscopy (ICPMS) to quantify iron and copper in ex vivo
healthy human arteries and carotid lesions. The EPR spectra
detected are characteristic of nonheme Fe(III) complexes.
Statistically elevated levels of iron were detected in the
intima of lesions compared with healthy controls (0.370
versus 0.022 nmol/mg tissue for EPR, 0.525 versus 0.168
nmol/mg tissue by ICPMS, P<0.05 in each cases). Elevated
levels of copper were also detected (7.51 versus 2.01
pmol/mg tissue, lesion versus healthy control, respectively,
P<0.05). Iron levels did not correlate with the gender or
age of the donor, or tissue protein or calcium levels, but
cholesterol levels correlated positively with iron
accumulation, as measured by EPR. CONCLUSIONS: These data
support the hypothesis that iron accumulates in human
lesions and may contribute to disease progression.

Tom, if you are going to be both fair and honest, all sides
and functions about the roles of iron in normal health and
disease prevention need be discusssed. As posted, iron in
some of it's functions acts as an antioxident and disease
prevention tool to kill germs.

"Go do it then .. somewhere .. else .."

Tom, is the above to say this is your personal ng and that
research to the contrary of your theory is not welcome? Or,
does it mean you are not, as in the original, interested in
being fair or honest in the presentation of information?
