BONE RESORPTION AND Ca$sup 45$ TURNOVER IN GROWING RATS

Journal Article · · American Journal of Physiology (U.S.)
OSTI ID:4054200
A group of rats were mnintnined on a Ca/sup 45/ diet for 21 days, then sacrificed at varying time intervals after substituting a nonradioactive diet. The total calcium and calcium specific activity of several bones, blood, and urine were determined. After correcting for the dilution of radioactivity due to an increase in total bone calcium, it was found that there was little, if any, loss of Ca/sup 45/ from rapidly growing bones. When the growth of the bone decreased, a small measurable loss was detected. It was assumed this slow loss of Ca/sup 45/ represented bone resorption. Values for the rate of bone resorption are presented and their significance in the growth of the bone discussed. (auth)
