The effect of Kampo therapy (Japanese traditional herbal medicine) on the second derivative of the photoplethysmogram (SDPTG) was investigated. The SDPTG is the second derivative of the fingertip photoplethysmogram (PTG), which expresses the characteristics of the vascular system, the properties of peripheral vessels, and the state of blood flow. The subjects comprised 13 normal volunteers, 101 patients (21 males and 80 females; mean age 53±11 years) with 1 month of Kampo therapy, and 19 patients (4 males and 15 females; mean age 60±9 years) with 3 months of medication. Control subjects showed no significant changes in their vascular age after 1 month. Patients with a higher vascular age than expected before therapy showed improvement of their vascular age, after treatment for 1 month and 3 months. The difference between the vascular age and calendar age decreased from about 10 to 7 years after 1 month of therapy (n=65. p<0.001), and from about 9 to 4 years, after 3 months (n=11, p<0.01). Vascular age not only reflects organic vessel wall sclerosis due to arteriosclerosis, but also a vascular wall tone that is closely related to the autonomic nervous system. The change of vascular age within a relatively short period suggested a functional change rather than an organic change of the vessels.

Patients often complaint about their health, even if nothing is wrong with them upon concise objective examination. The complaints often imply the symptoms reflect more than one organ. Kampo treatment has the advantage of curing several symptoms at the same time, with only one or a few medicines. Kampo medicines comprise Chinese herbal formulations individually tailored to the patient. Therefore, symptom reduction is one of the most essential outcome parameters in Kampo treatment. However, how these subjective symptoms should be quantified, is controversial. The purpose of the current paper is to introduce an evaluation system for subjective symptoms. The system is referred to as Tokyo Women's Medical University Oriental Medicine Research Active Support System (TOMRASS). Apart from subjective symptoms, this database contains physical examination, laboratory data, clinical diagnosis and prescribed medicines, etc. In this study, 2 cases are shown as examples of practical use with TOMRASS use. One is a case with many complaints, which is effective with one medicine, Toki-shigyaku-ka-goshuyu-shokyo-to. The other is a case, which reveals unexpected outcomes with Sho-seiryu-to.
The new approach enables us not only to give more consideration to the patient's perspective, but also to differentiate therapeutic implications. The investigation between the subjective quality of life and therapeutic relationship may contribute to further understanding of Kampo treatment.

The purpose of the present study was to examine the importance of the agonist muscle activity of the post-impact 30 ms phase during drop jump (DJ) for effective rebound performance by comparing those of sprint runners and swimmers. The eight sprint runners (SPRINT) and twelve swimmers (SWIM) were participated in this study. They performed DJ from a 0.3-m height box with maximal rebound efforts. Electromyograms (EMG) of the lower leg muscles (medial gastrocnemius [MG], soleus [SOL] and tibialis anterior [TA]), and vertical ground reaction force together with kinematic data were measured simultaneously during DJ. In addition, the onsets of fascicle stretching of the MG and SOL muscles were measured by using high-speed ultrasonography (521Hz) during DJ. The onsets of the fascicle stretching of SOL during DJ were not significantly different between SPRINT and SWIM (15 ± 7 ms and 16 ± 6 ms, respectively). During DJ, SPRINT showed onset of the SOL EMG before the ground contact (-26 ± 19 ms). Meanwhile, SWIM showed the onset of the SOL EMG after the ground contact of DJ (16 ± 19 ms). These results suggest that the SOL muscles for SWIM cannot be fully-activated during the braking phase. Consequently, the rate of force development during the braking phase of DJ and subsequently rebound height could be reduced in SWIM.
