Abstract
Guinea pigs were immunized with human serum and albumin of chicken egg. Antigen and antibody were investigated by immunofluorescent method. Antigen for antihuman immunoglobulin (goat) was found widely in the membranous labyrinth, but antibody for albumin of chicken egg was found only in the limbus.
In cases of the endolymphatic hydrops which was made by the endolymphatic sac obliteration, IgG was found widely in the membranous labyrinth including the aqueduct. In cases of acute acoustic trauma of the cochlea, IgG was found only in the endolymphatic sac and on the floating cells in vestibular aqueduct.
