We report a 48-year-old man who suffered from viral encephalitis and developed involuntary movements of the hands and astatic seizures as sequelae. T2-weighted magnetic resonance imaging of the brain showed high intensity areas in the bilateral insulae. Electroencephalography (EEG) revealed spike and slow wave complexes and high-amplitude slow waves. The(More)
The recording of the objective pulse diagnosis was performed and the meridian points were selected from this recording. The proper meridian points (five element points) according to the five element theory and the improper points (non-five element points) were stimulated. Pain threshold was elevated by the stimulation of five element points and not raised(More)
BACKGROUND The aim of this study was to investigate whether the lymph node ratio (LNR) was associated with the prognosis of patients, who underwent surgery for pathological N2 non-small cell lung cancer (NSCLC). METHODS A total of 182 patients were diagnosed with pathological N2 disease and underwent complete resection surgeries with systematic(More)
BACKGROUND Upper airway obstruction and inadequate ventilation often arise during sedation and anesthesia by benzodiazepines. To estimate the influence of benzodiazepines on the respiratory control, we studied the effect of diazepam and flumazenil on the neural activity and the respiratory response caused by a brief (60 sec) respiratory arrest (RA) observed(More)
A new method for testing Eustachian tube function using an otoadmittance meter (Tubotympanometry) is reported. The otoadmittance meter is set for the aural reflex test, namely in the position of Y-T- recording. The patient is asked to carry out deep breathing. Valsalva's maneuvre, normal breathing, and swallowing in succession. In normal 40 ears, three(More)
The effects of acupuncture analgesia were studied using the change in halothane MAC in volunteers. Halothane MAC under electrical acupuncture stimulation was reduced to 86.2+/-11.1% from the control value. After naloxone administration the level of the MAC was raised to the control level and the increment was 19.1+/-14.8%. Naloxone itself did not change the(More)
Observations have been made on the effect of intermittent intense sound stimuli, using the CM as an index. Experiments were conducted regarding the effectiveness of the drug CoQ10 in ameliorating the acoustic injury due to this traumatization. The CM was measured by the differential electrode method from the basal turn of the cochlea. The individual(More)
