微循环血流的自动调节功能是当血压变化时,维持血流相对稳定。应用激光多普勒法、氢廓清法及内淋巴氧分压测量法,观察正常及内淋巴水肿豚鼠的耳蜗微循环自动调节功能。同时比较了血压变化时耳蜗与脑干微循环自动调节功能,以及耳蜗氧分压与外半规管内淋巴氧分压变化的不同。实验中应用肾上腺素升高 Microcirculation automatic adjustment of blood flow is when blood pressure changes, to maintain relatively stable blood flow. Laser Doppler echocardiography, hydroexamination and endolymphatic pressure measurement were used to observe the cochlear microcirculation autoregulation in normal and endolymphatic hydrops. At the same time, we compared the autoregulation of cochlear and brainstem microcirculation in the changes of blood pressure, and the difference of oxygen partial pressure in the cochlea and the change of partial pressure of the lymphatic system in the lateral semicircular canal. Epinephrine increased in the experiment
