M. Rakovic et al., DETERMINATION OF THE SODIUM-TO-CALCIUM RATIO IN FEMORA OF NORMAL AND DIABETIC RATS BY INAA, Journal of radioanalytical and nuclear chemistry, 199(6), 1995, pp. 471-476
The Na-to-Ca ratio has been determined in femora of normal rats, untre
ated diabetic rats and diabetic rats treated with ascorbic acid. The d
etermination was based on short-term activation and counting of the Na
-24 and Ca-49 activities in the relevant photopeaks. The Na-to-Ca rati
os were significantly increased in both treated and untreated diabetic
animals as compared to intact controls due to increased Na contents i
n the diabetic rats.
