DALLAS - For women,
the signs of a hot flash are unmistakable.
Hot flashes study

like right now," said Sara Lester, who has endured hot flashes for
15 years.
Sick of suffering,
she slipped into a skin-tight, scuba-type suit for an unusual experiment
at Presbyterian Hospital.
"We know with
a hot flash the skin increases blood flow and it sweats, but we really
don't know why that is and what's going on with the body," said Craig
Crandall, UT a Southwestern researcher.
Lester's body is among
the menopausal volunteers wired and monitored to find out specifically
which nerves are triggered by hormones in a hot flash.
As a second part of
the experiment, researchers are using Botox. Botulinum toxin is known
to paralyze nerves responsible for wrinkles. It also blocks the sweating
response.
So, scientists are
working to see if Botox works for hot flashes.
"Botox prevents
certain nerves from firing," Crandall said.
For this hot flash
experiment, only browline nerves that are set off in a hot flash are being
injected with Botox. Scientists want to see if the patient gets relief
from heat and perspiration in the forehead area in the weeks following
the Botox treatment.
"With that information,
then perhaps we can find other agents that might be not like Botox but
have similar effects without adverse affects, because clearly we're not
going to give Botox throughout the body," Crandall said.
This trial is only
in the beginning phases.
But, researchers are
looking for more menopausal volunteers to give the experiment a try. The
ultimate hope is to develop new drugs to stop symptoms of a hot flash.
They believe if Botox works, it could be a win-win situation for women.
