人类卵巢淋巴孔的发现及其意义

THE DISCOVERY OF OVARY LYMPHATIC STOMATA IN HUMAN AND ITS SIGNIFICANCE

目的 研究人类卵巢淋巴孔的超微结构 ,并与动物卵巢或卵巢囊淋巴孔比较以探讨其功能。 方法取手术切除的新鲜卵巢组织 ,进行常规和NaOH消化扫描电镜观察 ,应用Elescope计算机图像处理软件对人类卵巢淋巴孔作定量处理。 结果 在扫描电镜下 ,人类卵巢上皮细胞可区分为扁平细胞和立方细胞。在立方细胞间、立方和扁平细胞之间有成簇或散在分布的淋巴孔 ,其直径 1 80± 0 82 μm ,周长 6 2 7± 2 6 5 μm。同时发现卵巢囊腺瘤瘤壁外表面也存在淋巴孔。 结论 人类正常卵巢上皮细胞之间 ,以及卵巢囊腺瘤瘤壁外表面都存在卵巢淋巴孔 ,藉卵巢淋巴孔使卵巢内淋巴管与腹膜腔相沟通 。

Objective To study the ultrastructure of ovary lymphatic stomata in human and compared with the animals′. Methods The morphology of human ovary surface was examined using scanning electron microscopy and the lymphatic stomatas were counted by the ELESCOPE computer image processing system. Results The human ovary epithelium was composed of cuboidal and flat cells. There were lymphatic stomatas not only among the cuboidal cells, but also among the cuboidal and flat cells. The stomata were usually circular in shape and about 1 80±0 82?μm in diameter, 6 27±2 65?μm in circle. Lymphatic stomata in external surface of ovary mucinous tumor was also found. Conclusion There are ovary lymphatic stomatas in human. These stomatas connect lymphatic vessels in ovary with the peritoneal cavity. They also present morphological basis for early\|metastasis of ovary tumor. [
