Radioactive iodine(I131) in doses of 30∼50 μc were orally given to 68 female thyroid patients consisted of 32 hyperthyroid, 28 euthyroid and 8 hypothyroid. The variations of I131 percents excreted per dose through the cervical mucus, vaginal secretion and saliva according to the thyroid function states and also to the ovarian cycles were detemined. Following were the results: 1) The I131 excreted though the cervical mucus, vaginal seretion and saliva varied according to the thyroid function states, namely, higher in the hypothroid, lower in the hyperthyroid, and mediate in the euthyroid. 2.) The I131 excreted through the cervical mucus also varied according to the ovarian cycles, namely, higher in the luteal than in the follicular phase in cases of the hypo-, and eu-thyroid. However, such a pattern was not observed in the hyperthyroid. 3) The I131 excreted through salive were about 4 times higher than that through the cervical mucus at 1∼3 hours intervals.
