[Intravital microscopic and laser Doppler method estimates of cochlear blood flow--effect of transient ischemia on inner ear blood flow].

Cochlear blood flow (CoBF) was measured by intravital microscopy (IVM) and laser Doppler (LD) methods in normal guinea pigs and after a single norepinephrine (NE) injection into the carotid artery. CoBF changed in proportion to BP changes in normal animals. CoBF values by LD correlated well (r = 0.
