effects of stem cells on stroke
University of Edinburgh, Scotland, say doctors injected stem cells into
the brains of five patients who had a stroke to improve movement and
balance them without consciousness can have side effects. However,
scientists say it is too early to conclude on the usefulness of this
therapy. For the experimental treatment, nine patients who were 60 to
90 years of age and be safe in their method was still being debated.
All these patients had a stroke six months to five years. Then the
parts of the brain that was damaged due to stroke, embryonic stem cells
were injected. Professor Keith Muir of Glasgow University professor who led the
research, said the improved performance of patients with mild to
moderate surprised because even expect to improve on one of them is not.
It can not yet be said with certainty whether this improvement is due
to the injection of stem cells or because the patient during treatment
is considered. It had been thought that six months after the stroke,
the brain of patients with stroke symptoms will improve. But according
to Professor Muir changes "cool" and "amazing" were seen in these
patients, ie, patients who had been completely paralyzed for years now
moves the fingers. "We saw the patient before it begins to move in the
house while they needed help to move around the awareness of some
patients with what is happening better.
This little changed everyday tasks like getting dressed can help
patients make better and less dependence on others. Given the positive
results obtained in the first phase of the study, the second phase will
start this. This step should be to ask the patient how much is due to
stem cell therapy. Secondly, even if the use of stem cells prove to be
beneficial, as long as this method is widely used, it takes years. The
third form of research that should be done, researchers will answer the
question for whom this treatment is useful and at what stage of the
disease, the treatment did stem cell.
The use of embryonic stem cells is that the critics do not ethical.
Lord Alton of anti-abortion activist says, "Sure, the fetus can not
consent to the use of Bnyadyash cells and this raises important ethical
