Capillary constriction in cochlear and vestibular tissues during intense noise stimulation

Capillary constriction in vestibular and cochlear tissue of rats was noted in response to stimulation with high level sound. Reduction of internal capillary diameter appeared to be caused by the thickening of capillary walls by the accumulation of nuclear masses. This constriction of blood flow is c...

Zusammenfassung:Capillary constriction in vestibular and cochlear tissue of rats was noted in response to stimulation with high level sound. Reduction of internal capillary diameter appeared to be caused by the thickening of capillary walls by the accumulation of nuclear masses. This constriction of blood flow is considered to be one factor in noise trauma reactions.
