Nerve Regeneration
Topic: New ways to aid in nerve regeneration. General Purpose: To inform
Specific Purpose: To inform the audience about news techniques and mechanisms
that aid in nerve regeneration. Central Idea Statement: The new techniques for
nerve regeneration involving magnetic, electrical, and chemical mechanisms look
very promising. INTRODUCTION I. The site is rather common: someone in a wheel
chair unable to use their lower body, or worse, unable to function from their
neck down because of an accident. You may even know one of these people. They
all have one thing in common: spinal nerve injury. To the majority of us, one of
the more famous and recent cases involving spinal trauma is that of Christopher
Reeve, known to most of us as Superman. Reeve was riding his horse when he fell
off, landed on the back of his head and twisted his neck. His spine was damaged
near the second cervical vertebrae; that being two vertebrae away from the base
of the skull. He states that after his accident he saw a handbook written in
1990 that "didn't even mention anyone higher than [the fourth cervical
vertebrae] because 70 percent of them didn't live longer than five days. I am
very lucky my injury happened at a time when treatment and surgery had
improved." Dr. Cotman from UCI, who worked with Reeve says that Reeve
remains optimistic that a cure is only a few million dollars away. II. Prior to
the end of the Second World War, if a person survived a severe spinal cord
injury, the injury still usually resulted in their early death. This was because
of complications that accompanied the injury, such as infections to the kidneys
and lungs. Though the development of new antibiotics has greatly improved life
expectancy, until recently medical science had not been able to restore nerve
function. III. According to researchers at the University of Alabama using data
from the regional SCI Centers, there are 7,800 traumatic spinal cord injuries
each year in the US. Yet these numbers do not represent accurate figures since
4,860 per year, die before reaching the hospital. Current estimates are that
250,000-400,000 individuals live with spinal cord injury or dysfunction;
forty-four percent of these occur in motor vehicle accidents. More than half of
these injuries occur to individuals who are single, and more than 80% of these
individuals are male. IV. Within the last five years, a great many things have
been happening in the area of neurological research. Research and trea...
