Figure 7

(a, b) Vertical slices of cochlea in Group A ( ); clumps of cells colored brown in scala tympani could be seen, indicating positive enzyme reactions. The lips of the osseous spiral lamina also showed positive staining (indicated by the arrow). (c) Vertical slice of cochlea from a guinea pig in Group B ( ); clumps of cells were seen in scala tympani (indicated by the arrow). Neither the clumps of cells nor any other parts of the inner ear were stained brown. (d) Vertical slice of cochlea from a guinea pig in Group C; brown staining was not seen. Scattered blood cells in scala tympani were a result of the bleeding during the injection (indicated by the arrow).
