内淋巴囊的脉管分布

目的：通过对豚鼠内淋巴囊表面的脉管及其粘膜下层结构的研究，了解其对内耳功能的影响，方法：用碳素黑水加１０％甲醛进行左心室灌注，将豚鼠的颞骨标本用冬青油透明并进行显微检查及透射电镜检查。结果：内淋巴囊表面有非常丰富的血管网，而且与乙状窦有很密切的联系，内淋巴囊周围被毛细血管，微静脉，静脉和个别微动脉形成的一个细密的环状血管网所包绕。毛细血管周围有丰富的淋巴窦、毛细血管与淋巴窦构成一个完整、细密的网状

The submucosal structure of the endolymphatic sac of guinea pigs

To investigating the submucosal structure of the endolymphatic sac (ES),so as to analyse the role of ES in the function of inner ear. Method:The temporal bone of the guinea pigs were cleared inmethyl salicylate and inspected under a stereomicroscope. The ultrastructure of endolymphatic sac has been observed by transmission electron microscope. Result: The extensive vascular system around the sac and has compact contact with sinus sigmoid. Its submucosal space comprises both arterioles and venules, as well as lymphaticsinus. Conclusion: The result suggests that the ES is a very metabolically active structure and has a pressureregulating function. The disturbance of endolymphatic resorptive function seems to result endolymphatic hydropsafter the vascular supply poverty of endolymphtic sac. It's may be the causative factor of Menierefe disease.
