PURPOSE To investigate the effects of lomerizine, a Ca2+ antagonist, on the ocular tissue circulation in rabbits and on the circulation in the optic nerve head (ONH) and choroid in healthy volunteers. METHODS Lomerizine (0.1 [n=10] or 0.3 [n=11] mg/kg) or vehicle solution (n=11) was injected intravenously in urethane-anesthetized rabbits, and blood flow(More)
The auditory brainstem responses (ABRs) obtained from 28 normal healthy adults were studied using the ipsilateral and contralateral recordings from the positions of vertex and each mastoid to monaural stimulation. Each wave of ABRs recorded by ipsilateral and contralateral derivations to stimulation site showed slightly significantly differences. Comparing(More)
The effects of intravenously administered lidocaine on the cerebral cortical energy state and glycolytic metabolism were studied in rats. In one series, rats were divided into five groups according to EEG patterns, i.e., control, desynchronized, synchronized, seizure (1-min duration) and recovery groups. With lidocaine infusion (0.75 mg/min), there were no(More)
Factors affecting subjective tinnitus pitch and tinnitus tonality were analyzed with the use of the quantitative method II. Ninety-one patients with unilateral tinnitus of a single kind were studied. Major factors affecting subjective tinnitus pitch were pitch matched frequency, age, puerility and impurity of tinnitus tonality, and loudness of tinnitus. In(More)
