观察到15月龄雌雄ICR小鼠性腺摘除后第134天和180天的胸腺体积增大、重量增加;电镜下胸腺细胞分裂相多见,上皮性网状细胞、交错突细胞和巨噬细胞密度及其各自与胸腺细胞形成的花环密度明显增高,雄性尤甚。表明老龄小鼠性腺摘除后胸腺呈现明显的形态学逆转变化,至少持续到术后180天,保持性差。
Observed 15th and 180th days of thymus enlargement and weight gain at 15th and 180th days after gonadal removal in 15-month-old male and female ICR mice; thymocyte division is more common under electron microscopy; epithelial reticular cells, interdigitating cells, and macrophage density The density of garlands formed by them and their respective thymus cells increased significantly, especially for males. It was shown that the thymus showed a reversal of morphological changes after gonadal enucleation in aged mice, which lasted at least 180 days after surgery and was poorly maintained.
