title: Distribution of 140La and 47Ca in female Japanese quail and in the eggs laid.
abstract: 140La accumulations in 20 tissues and tissue products of laying Japanese quail 1, 6 and 18 hr. after an intravenous dose of 15 mumol. La/100 g. body weight were greatest in the liver (43.1% at 18 hr.) and the growing oocytes (8.19% at 18 hr.). 47Ca accumulations 6 hr. after intravenous injection as compared with 140La levels were: shell 87.7% Ca, 0.0028% La; liver 0.110% Ca, 38.5% La; oocytes 0.852% Ca, 6.50% La. La3+ administered with the 47Ca did not alter the 47Ca levels. Deposition in eggs laid over an 8-day period was: 47Ca, shells 95.7%, maximum 77.6% on day 1; 140La, yolks 25.3%, maximum 8.35% on day 4.
