  • Title: [Cochlear and retrocochlear deafness induced by immunity with different inner ear tissue antigens].
    Author: Tan C, Cao Y, Liu H.
    Journal: Lin Chuang Er Bi Yan Hou Ke Za Zhi; 1998 Aug; 12(8):370-3. PubMed ID: 11263162.
    Abstract:
    OBJECTIVES: To inquire into whether the different inner ear tissue antigens could cause different kind of hearing loss, and to find out the disorder positions of auditory system. METHODS: The basilar membrane (BM), spiral ligament (SL), and spiral ganglion (SG) of guinea pigs were removed for making antigens, respectively. Then, we used these antigens to immune guinea pigs. The special humour and cellular immune reaction, hearing function, and inner ear histopathological changes were observed. RESULTS: In BM-antigen and SL-antigen immune group, the various degrees of cochlear microphonic potential disturbance, recruitment, and immune pathological inflammation in cochlear duct and stria vascularis were found. In SG-antigen immune group, auditory nerve compound action potential changes were prominent, and the inner ear pathological damage mainly existed in cochlear axis vessels or surround areas, and SG. CONCLUSIONS: It was confirmed that the inner ear antigens come from different part of auditory system, which could cause cochlear or retrocochlear autoimmune disease.
