THE EFFECT OF WHOLE-BODY X-IRRADIATION ON THE ABSORPTION OF CALCIUM-45 AND STRONTIUM-85 FROM THE INTESTINAL TRACT OF THE RAT
Young and mature male albino rats were subjected to whole-body x irradiation (285 kvp) in an effort to determine whether the absorption of radiostrontium and radiocalcium could be altered by such a procedure. The data showed that 200 r significantly increased the amount of Sr/sup 85/ and Ca/sup 45/ crossing the intestine of the young rat, but 1000 r and 400 r were needed in the mature rat to increase the passage of Sr/sup 85/and Ca/sup 45/, respectively. The irradiation did not appear to alter the uptake of the radionuclides by bone, and it was concluded that the defect was produced at the intestinal level. The increased absorption of radiostrontium and radiocalcium was evident as early as 2 hr and as long as 48 hr after irradiation. Feeding and/or fasting the animals before and after irradiation had no effect on the results. (auth)
