Title of Conversation: Grizzly bear hibernation- What can we learn?
During a 5-6
month hibernation, grizzly bears do not eat, drink or eliminate body wastes yet
they are able to maintain healthy organ function. We are interested in how
grizzly bears are able to maintain normal heart function during this period, at
heart rates that would result in congestive heart failure in a person. We have
hand-raised 2 grizzly bears cubs that we are able to study heart function
non-invasively (with ultrasound) and without sedatives or drugs. Preliminary
results will be discussed.
