Historically, modern Western medicine has developed with the natural science which is based on element reduction theory. On the other hand, Kampo medicine recognizes human beings as a whole, which has cumulated empirical knowledge based on the “Sho” concept. This lecture intends to make clear both the meaning of the “Sho” concept in the field of medicine, problems which we have to overcome in the future, and then propose ways to develop the “Sho” concept as a holistic medical system.

Obstructive sleep apnea syndrome (OSAS) is characterized by recurrent obstruction of the upper airway, causing apneas that are associated with oxygen desaturation and frequent arousals from sleep. The diagnosis of OSAS is usually obvious, presenting features of snoring, excessive daytime sleepiness, general fatigue, and obesity. Hochuekkito is a KAMPO medicine, Indicated for general fatigue, lack of will power, weakness of arms and legs, daytime sleepiness, gastric ptosis, hemorrhoids, prolapsus ani, ptosis of the uterus, and impotence.
Weakness of the upper airway dilator muscles induces obstruction of upper airway, and apnea. Hochuekkito may improve the muscle tone of the upper airway. The effect of Hochuekkito were studied in 13 patients with OSAS (5 patients diagnosed by polysomnography and 8 patients diagnosed by apnomonitor). The results indicate that there exist statistically significant differences in apnea index (AI) and desaturation (AI 23.1±4.8→9.6 ±2.6/h., mean SaO₂ (%) 83.7±0.7→94.0±0.9, p<0.05, mean±SD). We conclude that Hochuekkito increases the upper airway activity causing reduction of sleep apnea and snoring.

We administered Bofutsushosan (Bo) to 127 obese patients who consulted our clinic, and investigated the effect of this herbal formula on reducing body weight in 33 obese patients who received continuous adminis tration for more than six months. The abdominal muscle tension of these 33 patients was assessed mainly as “strong” (four) under the five-grade scale of Kampo diagnostics, which was higher than that of 9 other patients with side effects (including diarrhea and abdominal pain) assessed mainly as “middle” (three). Sixteen patients reported a decrease in appetite following administration of Bo. Weight before medication in the patients with decreased appetite was 67.1±2.5kg, and that in 17 patients with unchanged appetite was 75.9±2.4kg. There was a significant difference between the two. Weight change in the patients with decreased appetite was -4.8±1.0kg and was significantly lower than -1.4±0.7kg in the patients with unchanged appetite. Their blood triglycerides levels decreased significantly following administration of Bo. This decrease in appetite was considered to be due not only to activation of the adrenaline β₃ receptor, through the administration of Ephedrae Herba, Schizonepetae Spica, Rhei Rhizoma, Forsythiae Fructus and Glycyrrhizae Radix but also to the psychotropic actions of Ephedra Herba, Rhei Rhizoma and Gardeniae Fructus. Recently severe side effects of Bo have been reported. This study suggested that patients showing a grade of strong (four) or more in abdominal muscle tension, were indicated for this treatment and that the long-term administration of this herbal formula should be continued in patients whose appetite was identified as being suppressed.

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.

Ogikeishigomotsuto is a Kampo formula used for numbness or body pains. We experienced 29 cases in which attending physicians believed the drug would be effective. In 18 cases the drug was effective and in 11 cases it was not. We analyzed the difference in subjective symptoms between the responder group and the non-responder group. We concluded that some symptoms could be indicators for choosing the formula. Hypersensitivity to cold and heaviness of the whole body has previously been reported in many articles. In our cases, we observed a high incidence and specificity of the symptoms reported above, as well as arthralgia, dry skin and irritability in the responder group compared to the non-responder group. We believe these newly detected subjective symptoms can also be indicators for choosing Ogikeishigomotsuto.

Recently, the number of physicians using Kampo (Japanese traditional herbal) medicines has been increasing in Japan, and it is becoming more common for pharmacists to dispense Kampo medicines. As Kampo medicines become more popular, in addition to extract formulae, the use of decocting formulae that are more suited to each patient's predisposition and symptoms has increased. Therefore, more pharmacists are dispensing such decocting formulae. However, dispensing decocting formulae can be a complicated task. The risk of dispensing errors is not small. In present paper, we examined preventive measures based on investigations of errors involving decocting formulae in our Kampo clinic. From 1990 to 1999, there were 54 cases in which errors were found after patients received their medicines, and 44 of these cases were dispensing errors. To prevent such errors, in addition to having the knowledge of Kampo medicine and medicinal herbs that is needed for dispensing decocting formulae, it is also necessary to understand the contents of the prescription. The most important preventive measures are to re-inspect the weight and contents of the prescription after preparing it, and to do a final inspection of the medicine contents with the patient. It is expected that this report will play a role in preventing dispensing errors of Kampo medicines by pharmacists.
