title: [Effects of acoustic stimuli on intracellular free calcium isolated cochlear OHC].
abstract: OBJECTIVE
  To study the effects of acoustic stimuli upon intracellular free calcium concentration ([Ca2+]i) of cochlear outer hair cells (OHCs) isolated from guinea pigs.
  
  
  METHODS
  The specimens were stained with fluorescence, and measured by using ACAS 570.
  
  
  RESULTS
  Acoustic stimuli caused a remarkable increase of [Ca2+]i and the concentration of [Ca2+]i decreased gradually after reaching its peak value. The reponeses can repeat with another stimuli.
  
  
  CONCLUSIONS
  The acoustic stimuli could alter the physiologic characteristics of single OHC.
