小睾丸组织超微结构变化与性激素相关性研究

目的 :探讨小睾丸组织超微结构变化和性激素改变及其相关性。　方法 :对 8例小睾丸病人和 12例健康成人血清进行性激素测定 ,光镜及电镜观察小睾丸组织的超微结构变化。　结果 :小睾丸病人和正常对照组血清性激素FSH、LH、T分别为 (2 1.0 5± 9.15 )IU/Lvs (6 74± 3 5 2 )IU/L、(2 2 .88± 6 .2 5 )IU/Lvs (6 6 0± 1 4 8)IU/L、(0 .30± 0 .0 4 )nmol/Lvs (17 5 5± 9 2 5 )nmol/L ,两者相比差异有显著性 (P <0 .0 1) ;精曲小管直径和管壁厚度分别为 (37.33± 6 .80 )、(10 .30± 1.82 ) μm ,与正常组的 (198 4 6± 2 9 84 )、(2 95± 0 2 0 ) μm相比 ,差异有极显著性 (P <0 .0 1) ;组织超微结构变化显著。　结论 :小睾丸组织精曲小管、生精上皮、支持细胞、界膜、间质细胞及血管均发生严重的病理改变 ,其形成可能与遗传和免疫反应有关

Correlation between Tissue Ultrastructure Changes of Small Testis and Sex Hormone

OBJECTIVES: To investigate the tissue ultrastructure changes of small testis and sex hormone and their correlation. METHODS: The patients were divided into small tests (n = 8) and control group(n = 12). FSH, LH, T were determined by radioimmunassay. Diameter and wall thickness of convoluted seminiferous tubule were investigated with light microscope and electro microscopy on small testis tissue morphology and ultrastructure. RESULTS: FSH, LH, T of small testis and control group were (21.05 +/- 9.15) IU/L vs (6.74 +/- 3.52) IU/L, (22.88 +/- 6.25) IU/L vs (6.60 +/- 1.48) IU/L and (0.30 +/- 0.04) nmol/L vs (17.55 +/- 9.25) nmol/L, respectively. Seminiferous tubule diameter and wall thickness were(37.33 +/- 6.80) microns vs (198.46 +/- 29.84) microns and (10.30 +/- 1.82) microns vs (2.95 +/- 0.20) microns. Small testis tissue ultrastructure changed significantly. CONCLUSIONS: Pathologic changes of small testis tissue in many parts such as seminiferous tubule, germinal epithelium, Sertoli cell, Leydig cell, limiting membrance and blood vessel may relate with genetics and immunoreaction.
