A total of 120 measurements were made for pulse waveform of the radial artery in 73 male subjects in their twenties to forties. We then calculated the parameters in the four-factor concentrated constant circuit model using the method we had developed. From the waveform of the radial artery, we extracted forms equivalent to those referred to as normal, slippery, and string-like pulses according to the pulse-wave models described in the literature. By comparing these parameters, we could show quantitatively the differences in waveforms and related diagnoses of pulses.

In engineering, when the degrce of distortion of the waveform of the signal is expressed numerically, a coefficient called a distortion factor is used. In order to determine whether or not itis possible to quantify the difference in pulse waveforms in terms of a distortion factor, the authors carried out a Fourier analysis of the pulse waves of 74 cases (74 males between 20 and 40 years of age), calculating the distortion factor of these pulse waves. Employing the pulse wave scale devised by Zhaofu Fei et al, the Ping mai, Hua mai and Xuan mai were differentiated by means of the amplitude ratio of the dicrotic notch to the ejection wave. As a result of a comparison between the distortion factors of these three groups, the authors were successful in quantifying the differences between the wave forms in terms of a distortion factor.

Purpose: We conducted a group seminar for lung cancer patients. The purpose of the group seminar was to eliminate the negative notions about opioids and to impart the right knowledge about these drugs. Further, we investigated the notions about opioids and the effectiveness of the group seminar. Methods: A pharmacist conducted a group seminar on opioids for lung cancer inpatients who agreed to participate in the group seminar. Moreover, we performed a questionnaire survey before and after the delivery of the group seminar. Results: Sixty patients answered the questionnaire. After completion of the group seminar, the understanding and knowledge about opioids increased, as indicated by the responses of the patients to all of the questions. Conclusion: Complete elimination of the negative notion about opioids could not be achieved through the group seminar. However, the group seminar was thought to be one of the useful methods of educating patients. If a patient resists treatment with opioids, control of pain may be delayed. This in turn would hamper improvement of the quality of life. Therefore, we consider that it is necessary that a patient has the right knowledge about opioids beforehand.
