Abstract

The present immunohistologic study demonstrates that cochlear strial blood circulation is markedly damaged in guinea pigs subjected to intense acoustic stimulation. In contrast, autonomic unbalance of the inner ear induced by resection or electric stimulation of the superior cervical ganglion has no appreciable effect on cochlear strial blood flow. In consequence, although strial blood circulation in the cochlea is susceptible to pathological change in some conditions, it does not appear to be affected by autonomic unbalance alone.
