...Hirofumi Yamamoto; Kazuo Makimoto; Michiro Kawakami; Yoshimitsu Ohinata; Hiroaki Takahashi To understand the importance of oxygen transport to the inner ear tissue, we studied, in guinea pigs, the relationship between cochlear blood flow and endocochlear direct-current potential (EP) under...

...Kiyotaka Asami; Tsutomu Nakashima; Hironobu Morisaki; Koichiro Akanabe; Kayao Kuno; Noriyuki Yanagita Cochlear blood flow (CoBF) and cerebral blood flow (CBF) were measured using laser Doppler flowmetry and the microsphere method during CO 2 and O 2 gas mixture inhalation in rabbits. Both methods...

... with control of arterial pH, endexpiratory CO 2 content, as well as blood pressure and body temperature. After a duration of noise exposure of 30–45 min the cochlear blood flow reached an average level of 80% of the initial point. This level remained mainly unchanged until the end of noise exposure (60 min...

...Hisako Ito In order to determine the effects on the cochlea of circulatory disturbance in the basilar artery system, the cochlear action potential (AP) and the cochlear blood flow were measured in cats with the artery occluded. The occlusion was performed in the basilar, the anterior cerebellar...

... in ICP were induced by intracranial infusion of Ringer solution prewarmed to body temperature. The increments were accompanied by an intravenous administration of prazosin to abolish the Cushing effect. The cochlear blood flow was unaffected by the intravenously administered prazosin. A decrease...

...H.C. Larsen; C. Angelborg Cochlear blood flow in the rabbit was determined before and after injection of hyperosmotic solutions of galactose and isosorbide. After doses similar to those which can produce hearing improvements in patients with Ménière’s disease, cochlear blood flow was increased...

...E. Hultcrantz; H.C. Larsen; C. Angelborg The cochlear blood flow was measured with the microsphere method before, during and after CO 2 inhalation in anesthetized rabbits. Different gas mixtures and exposure times were used. The greatest increase of cochlear blood flow was measured after 5 min...

...Yoshiro Yazawa; Hiroya Kitano; Mikio Suzuki; Hirosi Tanaka; Kazutomo Kitajima Laser Doppler flowmetry was used to assess cochlear blood flow (CoBF) in guinea pigs with experimental endolymphatic hydrops following intravenous infusion of 5 types of drugs: 50% glycerol, 70% isosorbide, 20% mannitol...
