Guest guest Posted March 6, 2003 Report Share Posted March 6, 2003 Well I don't know if peeing has anything to do with it. The inactivity of hibernation (or any prolonged inactivity) is associated with bone loss. Also when humans go into space they lose bone mass. Never heard of pee involved before. on 3/6/2003 5:43 PM, jwwright at jwwright@... wrote: > somehow lost the operative word. > ----- Original Message ----- > From: jwwright > > Sent: Thursday, March 06, 2003 3:23 PM > Subject: Re: [ ] osteo news > > > I would guess the Calcium has to go somewhere when the bear doesn't pee, > right? > ----- Original Message ----- > From: Francesca Skelton > support group > Sent: Thursday, March 06, 2003 10:56 AM > Subject: [ ] osteo news > > > The Journal of Clinical Orthopedics is reporting that they're studying the > reasons why bears can hibernate and not lose bone mass.

Guest guest Posted March 6, 2003 Report Share Posted March 6, 2003 If they don't pee, they can lose water only in evaporation. I think they don't excrete at all but they do suckle their cubs. Serum Calcium has to be controlled. So built to hibernate, they must a good supply of calcium. Now that I recall the suckling, it would seem their body would pass the extra Ca to the cub. Humans in space lose bone mass due to loss of gravity - less load - That's why the resistance exercise. They do not hibernate there. Might be an interesting experiment for you to PI when they fly next. And perhaps humans weren't built for space. There's are several other things humans can't do in space. Still, the idea the bear loses weight and NO calcium is intriguing since he's lugging around some hefty bones in spring. Is there someplace else we store Ca, other than bones and smooth muscle? I wouldn't think in interstitial.
