The 131I uptake by guinea pig thyroid is subject to distinct diurnal variation. In control males, peak values occurred at 12 h, and minima at 24 h. In control females, peak values were also at 12 h, but minima at 6 h. In guinea pigs irradiated with 500 R of X-rays, a rise in 131I uptake began 1 h after termination of irradiation in both sexes and at all intervals, but maximum and minimum values were at the same time as in controls.
豚鼠甲状腺对¹³¹I的摄取呈现明显的昼夜变化。在对照雄性豚鼠中，峰值出现在12小时，谷值出现在24小时。在对照雌性豚鼠中，峰值也出现在12小时，但谷值出现在6小时。在用500伦琴X射线照射的豚鼠中，两性在照射结束后1小时开始¹³¹I摄取增加，且在所有时间间隔都是如此，但最高值和最低值出现的时间与对照相同。
