    Notes: Abstract The orthostatic test was administered to 134 dizzy patients (37 males and 97 females) who were identified as having orthostatic dysregulation from December 1990 through November 1994. The mean age of the male and female patients was 42.5 and 44.6 years, respectively, and the peak age decade was the 50s. Among the questionnaire items for orthostatic dysregulation, orthostatic dizziness was the most frequent major symptom and occurred in 116 of the patients (86.6%). Fatigue was the most frequent minor symptom and was found in 97 (72.4%). The incidence of positive orthostatic test results in the patients with orthostatic dysregulation (50.7%) was significantly higher (P 〈 0.01) than that in the control subjects (27.8%). There was also a significant difference (P 〈 0.01 or P 〈 0.05) between systolic pressure decrease during the orthostatic test procedure in the patients with orthostatic dysregulation and that in the control subjects. These results suggest that autonomic imbalance as reflected by the orthostatic dysregulation questionnaire and orthostatic test results is closely related to the occurrence of dizziness or vertigo.

    Notes: Abstract Chlorine and oxygen evolving at RuO2/Ti and RuO2–TiO2/Ti anodes have been simultaneously determined at electrode potentials from 1.0 to about 2V (vs Ag/AgCl) by differential electrochemical mass spectroscopy (DEMS). On the RuO2/Ti anodes, the threshold electrode potential for oxygen evolution increased with a decrease in RuO2 loading, while the chlorine evolution potential was unchanged. Low RuO2 loading anodes gave a high chlorine evolution ratio under various constant electrolysis potentials. On the RuO2–TiO2/Ti anodes, the threshold electrode potential for oxygen evolution increased with an increase in the TiO2 content more remarkably than that for chlorine evolution. High TiO2 content anodes gave a high chlorine evolution ratio at various constant electrolysis potentials. The combination of RuO2 and TiO2 exhibits a remarkable effect with respect to the enhancement of chlorine evolution selectivity.
