CA-45 AND Sr-85 METABOLISM IN MAN. Progress Report for June 15, 1959- May 20, 1960
Bone formation rate in a normal, healthy, young adult was observed to be 0.521 g calcium/day. Calcium balance and bone formation and destruction rates were studied in patients with disuse osetoporosis associated with quadriplegia secondary to poliomyelitis and patients with senile and posmenopausal osteoporosis. Renal strontium/calcium discrimination, studied for nine cases, was given by a mean factor of 4.3. This factor means that, exposed to trace amounts of strontium and normal calcium loads, the human kidney will produce a urine containing 4.3 atoms of strontium per unit filtered strontium for each atom calcium per unit filtered calcium. The mean value for gastrointestinal discrimination between endogenously secreted Sr/sup 85/ and Ca/sup 45/ was 1.4. The ratio of strontium-determined pool to calcium- determined pool was 1.04 plus or minus 0.13 (1 S.D.) and the corresponding ratio for bone formation values was 1.04 plus or minus 0.32 (1 S.D.) for nine patients studied.
