[Observation on activity of carbonic anhydrase in the vestibule of guinea pigs].
The localization of carbonic anhydrase (CA) activity in the inner ear vestibule of guinea pigs were studied by histochemistry and cytochemistry. We found that numerous enzymatic reaction products were localized in the sterecocilia, cuticles of hair cells, no reaction product was seen in their cell bodies; revealed reaction products in the cell membrane, microvilli, lateral infolding and basolateral infolding of the supporting cell, dark cell, transitional cell and wall cell. It is suggeated that the CA is a membrane-associated CA and the membrane-associated CA plays an important role in the homeistasis of the vestibule and otolithic metabolism.
