Abstract

Laying Japanese quail were doubly-labeled with either 125I and 36Cl or 82Br and 36Cl. Eighteen-hour accumulations, expressed as percent of tracer doses, were: growing oocytes, 125I 48.2 vs. 36Cl 2.07, 82Br 4.01 vs. 36Cl 1.99; thyroids, 125I 10.6 vs. 36Cl .030, 82Br .027 vs. 36Cl .020. Concentrations (expressed as percent per gram) of the radionuclides in the growing oocytes and the thyroids as compared with concentrations in the plasma were: for oocytes, the mean 125I concentration was 199 times the mean plasma concentration, 82Br was .34 x and 36Cl was .13 x; for thyroids, 125I was 13,500 x, 82Br was .48 x, and 36Cl was .41 x the mean plasma concentration. Eight day totals for yolks of eggs laid were 125I 29% vs. 36Cl 3.7%.

摘要

对产蛋期日本鹌鹑分别用¹²⁵I和³⁶Cl或⁸²Br和³⁶Cl进行双重标记。以示踪剂剂量的百分比表示的18小时累积量如下：正在生长的卵母细胞，¹²⁵I为48.2%，³⁶Cl为2.07%，⁸²Br为4.01%，³⁶Cl为1.99%；甲状腺，¹²⁵I为10.6%，³⁶Cl为0.030%，⁸²Br为0.027%，³⁶Cl为0.020%。与血浆中的浓度相比，正在生长的卵母细胞和甲状腺中放射性核素的浓度（以每克百分比表示）为：对于卵母细胞，¹²⁵I的平均浓度是血浆平均浓度的199倍，⁸²Br是0.34倍，³⁶Cl是0.13倍；对于甲状腺，¹²⁵I是13500倍，⁸²Br是0.48倍，³⁶Cl是血浆平均浓度的0.41倍。所产鸡蛋蛋黄的8天总量为¹²⁵I 29%，³⁶Cl 3.7%。
