Oral curcumin may benefit patients with cancers of the gastrointestinal tract
November

According to recent research, "curcumin is a polyphenol derived from the herbal remedy and dietary
spice turmeric. It possesses diverse anti-inflammatory and anti-cancer properties following oral
or topical administration."
Curcumin has shown the ability to affect the carrying out of genetic instructions in living cells,
which subsequently directs protein manufacture, and has the ability to induce the spontaneous death
of cancer cells in preclinical models. This may "be of particular relevance to cancer chemoprevention
and chemotherapy in patients." When taken orally, curcumin is not absorbed enough in certain tissues
to have a beneficial effect. However, it does achieve results in the gastrointestinal tract, which
has been shown in animals and humans. This study is published in the European Journal of Cancer
(Curcumin: The story so far. Eur J Cancer, 2005;41(13):1955-1968).

Hopefully none of us will encounter an agent as destructive as mustard gas, but it is good for us
to note that these particular antioxidants are very lung friendly and that available oral
supplement levels have shown protective activity in research.
Resveratrol protects the spine from damage
The abdominal aorta is a large blood vessel that supplies blood from the heart to the abdomen,
pelvis and legs. If there is an aneurysm (a ballooning out of this artery like a weak spot on an
old tire) in the aortic artery and it bursts it can lead to fatal internal bleeding. Surgery is
often performed to repair an aortic aneurysm. Severe neurological injury is still one of the most
devastating complications after this surgery. The blood supply to the spinal cord can be affected
during this surgery leading to paralysis of the legs.
Sixteen rabbits had their abdominal aortic artery clamped for 30 minutes blocking the flow of blood
to the spine; an experimental model of spinal cord trauma. The rabbits were split into 2 groups and
received a large dosage of either Resveratrol or inactive placebo 15 minutes before clamping. The
rabbits were assessed 8 hours, 16 hours, and 24 hours after the procedure. The Tarlov score is a test
for locomotion and paralysis. The rabbits supplemented with Resveratrol had a much higher Tarlov score
averaging 4.38 versus the rabbits on placebo who were near paralyzed with a Tarlov score averaging
0.38. The measure of free radical activity was almost 50% less in the Resveratrol group with a much
lower measure of inflammation in the spine, and there was a much greater level of working brain-nerve
tissue in the Resveratrol group. The study was performed at the College of Physicians and Surgeons at
Colombia University and is published in the December 2005 issue of the journal The Annals of
Thoracic Surgery.
