【摘要】 目的通过研究严重急性呼吸综合征(SARS)患者甲状腺的病理学改变及甲状腺细胞所含激素的变化,探讨SARS发病过程中内分泌与疾病的关系。方法对4例SARS患者的尸体解剖甲状腺组织进行石蜡切片,HE染色观察甲状腺的结构;免疫组织化学染色观察甲状腺球蛋白的变化以及降钙素阳性细胞和甲状旁腺素阳性细胞的变化。结果SARS患者甲状腺的组织结构有较明显改变,可见数量、程度不等的滤泡变形、增大或萎缩,滤泡间结缔组织增生或间质血管扩张充盈;甲状腺球蛋白阳性细胞染色明显减弱(P<0.01),未见明显降钙素阳性细胞,甲状旁腺素阳性细胞较之正常组织其平均吸光度值差异无统计学意义(P>0.05),积分吸光度值(前者为3.4±1.8,后者为1.5±0.7)差异有统计学意义(P<0.01)。结论SARS患者甲状腺组织的形态结构明显改变,滤泡上皮细胞和滤泡旁细胞都被累及,同时提示两者的激素合成功能可能受到影响。更多还原

【Abstract】 Objective To study the pathological characteristics of thyroid gland and the changes on hormone content of thyroid cells in severe acute respiratory syndrome (SARS) patients. Method Hematoxylin and eosin staining and light microscopy were used to examine the histology of the thyroid tissues from 4 dead SARS patients and 5 healthy thyroid samples used as negative controls. Immunohistochemistry was used, with monoclonal antibodies, to detect the thyroglobulin (TG), calcitonin and parathyroid hormone (PTH) in the thyroid glands. Results Deformation, enlargement, and dystrophy of follicular cells in thyroid glands were found in the SARS patients. The normal follicular epithelial cells were strongly TG positive, however, the number and intensity of TG positive follicular epithelial cells were significantly lower in the SARS patients. Calcitonin positive cells were found in the normal thyroid glands and not in the thyroid glands of the SARS patients. PTH positive cells were seen in the normal thyroid glands and those of the SARS patients with a slightly weaker intensity of reaction, however, with significant difference in IOD (P<0.01) and without significant difference in mean slight absorption MOD (P>0.05). Conclusion The thyroid tissue structure and morphology in SARS patients were significantly changed, involving both follicular epithelial cells and parafollicular cells; which may imply that the hormonal production of follicular epithelial cells and the parafollicular cells were affected.更多还原
