| dc.description.abstract | The effect of administering the stable isotope of strontium (as phosphate) at different dietary levels to adult rats (fed on a cereal and pulse-based diet containing 0·4% Ca) on the retention of radiostrontium (89Sr) and radiocalcium (45Ca) in the femur and the whole skeleton was studied for a period up to 6 weeks after an intraperitoneal injection of the two radioisotopes. The ability of strontium to remove 89Sr under the above dietary conditions was examined. Feeding Sr at 0·5% or 1% levels for 6 weeks had no effect on the skeletal content of 89Sr or 45Ca while a dietary regimen of 2% Sr (2000 times the normal content), significantly lowered the 89Sr and 45Ca content by about 30% in the femur but not in the whole skeleton. At this Sr level, the urinary excretion of the isotopes increased with a concomitant decrease in their excretion in the faeces. This study underscores the limitations of dietary Sr to mobilise 89Sr from the bones after it is incorporated in the bone mineral. | en_US |
