Endothelin-1 immunoreactivity (irET-1) was observed in rat and porcine thyroid glands. Using a radioimmunoassay for endothelin-1, the mean concentration in extracts of rat and porcine thyroid glands were 0.75 pg/mg +/- 0.03 (n = 4) and 1.5 pg/mg +/- 0.2 (n = 8) (mean +/- SE) respectively. Gel-filtration and reverse-phase HPLC showed that ir ET-1 eluted in a position identical to synthetic endothelin-1. In addition, immunohistochemical study showed that irET-1 is located within epithelial follicular cells. No immunostaining was seen in parafollicular C-cells nor in parathyroid.
在大鼠和猪的甲状腺中观察到内皮素-1免疫反应性(irET-1)。使用内皮素-1放射免疫分析法,大鼠和猪甲状腺提取物中的平均浓度分别为0.75 pg/mg ± 0.03(n = 4)和1.5 pg/mg ± 0.2(n = 8)(平均值 ± 标准误)。凝胶过滤和反相高效液相色谱显示,irET-1在与合成内皮素-1相同的位置洗脱。此外,免疫组织化学研究表明,irET-1位于上皮滤泡细胞内。在滤泡旁C细胞和甲状旁腺中未观察到免疫染色。
