Bypass Surgery Might
Be History Soon !...
================
Dr.Ali Kareem
Medical Dept./ALN
•In a ground breaking discovery
that may eventually render
Bypass surgery history,
researchers have shown that an
injected protein can regrow
blood vessels in the human
heart.
•
•In heart disease, blood vessels are either
clogged or die off,
•starving the heart of oxygen and leaving
it highly susceptible to a cardiac attack.
•
•The team of researchers have developed
a protein-based injection that when
delivered straight to muscles in the body,
sparks the regrowth of tiny blood vessels.
The new vessels in the heart could give
millions of people around the world a
new lease on life.
"The biotechnology behind our
human-based protein therapy is very
complicated, but the goal is simple and
the solution is
straightforward..
We intend to inject our drug locally
So far in animal models, we''ve seen
no side effects and no
inflammation following our injection
of the drug into the legs. The growth
of new blood vessels happens within a
few weeks, showing improved blood
circulation," .
to heal any oxygen-starved tissue
The protein solution can also be
added as a coating to a stent.
Usually, the implantation of a stent
is accompanied by a high risk for
blood clots, which necessitates the
use of blood thinners.
"We could coat a stent with our
peptide, attracting endothelial
stem cells to form a film on the
surface of the stent. These
endothelial cells on the stent
would eliminate the need for
taking the blood thinners that
prevent blood clots from forming .
If investment goals are met, the
researchers are hoping that toxicity
studies and Phase I trials could be
complete within two years.
The researchers began the study for
preventing leg amputations, positing
that proteins from the human body
could be used to trigger the growth of
new blood vessels.
Hardy started by studying a library of
peptides and testing them in the
laboratory and later confirmed initial
results. They then took some of the
isolated and synthesized peptides and
tested them in diabetic mice whose
legs were in the process of dying.
Although diabetes is known to
decrease blood circulation, The
team found that her therapy
reversed the decrease. "Within a
short time we saw the formation of
capillaries and tiny blood vessels.
After three weeks, they had grown and
merged together with the rest of the
circulatory system," they said. In mice
with limited blood circulation, she was
able to completely restore blood
vessels and save their legs.
It was then a short step to studying the
applicability of the research to cardiac
patients. "It''s pretty obvious if there is
regrowth or not.
Our technology promises to regrow
blood vessels like a net, and a heart
that grows more blood vessels
becomes stronger.
It's now imaginable that, in the
distant future, peptide injections
may be able to replace bypass
surgeries. The study has been
published in Biochemical
Pharmacology
