Different dosages of 125I-toluidine blue and 75Se-selenomethionine were injected intravenously into rabbits, and the concentration of radioactivity was measured in the parathyroids and surrounding tissues. The response of i.v. injected glucagon was also determined. It was found that 0.16 mg 125I-toluidine blue gave a concentration ratio of parathyroid/thyroid and parathyroid/muscle which was significantly higher than both lower and higher doses at 1 minute after i.v. injection of the labelled dye. Glucagon had little or no effect on the uptake of 125I-toluidine blue and 75Se-selenomethionine.
将不同剂量的¹²⁵I-甲苯胺蓝和⁷⁵Se-硒代蛋氨酸静脉注射到兔子体内，然后测量甲状旁腺及周围组织中的放射性浓度。同时也测定了静脉注射胰高血糖素后的反应。结果发现，静脉注射标记染料1分钟后，0.16毫克¹²⁵I-甲苯胺蓝所产生的甲状旁腺/甲状腺和甲状旁腺/肌肉的浓度比显著高于较低和较高剂量。胰高血糖素对¹²⁵I-甲苯胺蓝和⁷⁵Se-硒代蛋氨酸的摄取几乎没有影响。
