Guinea pigs were immunized with human type I, type II or type III collagen. Inner ear lesions were induced in some guinea pigs by immunizing them with human type II collagen. Histopathologic changes included endolymphatic hydrops, organ of Corti lesions and endolymphatic duct contained a large number of inflammatory cells. These histologic changes resembled those observed in patient with Meniere's disease. We didn't discover any inner ear lesions in guinea pigs by immunizing them with human type I and type III collagen, although their serum antibody titers were high and antibody presented in perilymph. Immunohistochemical study showed the presence of type II collagen in the cochlea tissues--spiral ligament, basilar membrane, tectorial membrane, spiral limb and Rosenthal's canal. We didn't discover type I and type III collagen in these area.

D009925	Organ of Corti	The spiral EPITHELIUM containing sensory AUDITORY HAIR CELLS and supporting cells in the cochlea. Organ of Corti, situated on the BASILAR MEMBRANE and overlaid by a gelatinous TECTORIAL MEMBRANE, converts sound-induced mechanical waves to neural impulses to the brain.

D003051	Cochlea	The part of the inner ear (LABYRINTH) that is concerned with hearing. It forms the anterior part of the labyrinth, as a snail-like structure that is situated almost horizontally anterior to the VESTIBULAR LABYRINTH.	Cochleas
D003094	Collagen	A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of SKIN; CONNECTIVE TISSUE; and the organic substance of bones (BONE AND BONES) and teeth (TOOTH).

D004711	Endolymphatic Duct	The part of the membranous labyrinth that traverses the bony vestibular aqueduct and emerges through the bone of posterior cranial fossa (CRANIAL FOSSA, POSTERIOR) where it expands into a blind pouch called the endolymphatic sac.

D005620	Freund's Adjuvant	An antigen solution emulsified in mineral oil. The complete form is made up of killed, dried mycobacteria, usually M. tuberculosis, suspended in the oil phase. It is effective in stimulating cell-mediated immunity (IMMUNITY, CELLULAR) and potentiates the production of certain IMMUNOGLOBULINS in some animals. The incomplete form does not contain mycobacteria.	Freund Adjuvant,Adjuvant, Freund,Adjuvant, Freund's,Freunds Adjuvant

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
