The ontogenesis of nuclear triiodothyronine receptors was determined in the pectoralis (alpha W fibers: fast contracting, glycolytic metabolism), adductor brevis (alpha R fibers: fast contracting, oxido-glycolytic metabolism) and adductor magnus (beta R fibers: slow contracting, oxidative metabolism), muscles of male and female chickens at 18 days in ovo and 0, 6, and 30 days ex ovo. In the fast muscles (adductor brevis and pectoralis major), the T3 receptor number decreases from the 18th day of incubation to hatching or the 6th day after hatching, respectively, and then increases. In the slow muscle (adductor magnus), the T3 receptor number increases from 18 days in ovo to hatching and then decreases. At 30 days after hatching, the number of T3 receptors was higher in the fast muscles than in the slow one. A comparison of the two fast muscles reveals that the number of T3 receptors was more elevated in the pectoralis (glycolytic) fibers than in the adductor brevis (oxido-glycolytic) fibers. An overall test of significance showed a higher number of T3 nuclear receptors in muscles from females than from males.
在雄性和雌性鸡胚发育18天以及出壳后0、6和30天，测定了胸肌（αW纤维：快速收缩，糖酵解代谢）、短收肌（αR纤维：快速收缩，氧化-糖酵解代谢）和大收肌（βR纤维：缓慢收缩，氧化代谢）中核三碘甲状腺原氨酸受体的个体发生。在快肌（短收肌和胸大肌）中，T3受体数量分别从孵化第18天到孵化时或孵化后第6天减少，然后增加。在慢肌（大收肌）中，T3受体数量从胚胎18天到孵化时增加，然后减少。在孵化后30天，快肌中的T3受体数量高于慢肌。对两块快肌的比较显示，胸肌（糖酵解）纤维中的T3受体数量比短收肌（氧化-糖酵解）纤维中的更高。总体显著性检验表明，雌性肌肉中的T3核受体数量高于雄性。
