观察了用牛内耳抗原全身致敏后，豚鼠耳蜗的连续切片。发现正常的对照组动物内淋巴囊的骨通道间隙小，弯曲，并含有极少量的免疫细胞，仅有1例例外，在其内淋巴囊的中间部分有一较大的骨通道。在对照组和致敏组中，内淋巴囊远端偶尔可见连接硬脑膜的通道扩大，但是，即使是这些 Serial sections of guinea pig cochlea were observed after systemic sensitization with bovine inner ear antigen. The normal control animals were found to have a small, curved bone channel with a minimal amount of immune cells within the lymphatic sac, with the exception of one having a larger osseous passage in the medial portion of the endolymphatic sac. In the control group and the sensitized group, the distal end of the endolymphatic sac may occasionally see an enlargement of the passage connecting the dura, however, even these
