Kampo Formula-Pattern Models: The Development of 13 New Clinically Useful Standard Abdominal Pattern Models in the Fukushin Simulator.

Aim: In Kampo medicine, there exists an important system of diagnosis called Fukushin, or abdominal diagnosis or palpation. By applying pressure to the abdomen of the patient, the physician can gain important information on the patient's physical state and use those indications to choose a suitable Kampo formulation. We have previously developed a Fukushin simulator, a teaching tool that reproduces the important abdominal patterns that doctors will encounter in clinical practice and that has received favourable feedback for students and practitioners. In order to make diagnosis and prescription easier, it is desirable to have matched formula-pattern pairings. The present study aims to develop such pairings. Methods: With the previously developed models as a foundation, in the present study the production team (two members) used materials such as urethane foam and silicone rubber to build an additional 13 standard abdominal pattern models matched to Kampo herbal formulas commonly used by practitioners in Japan. Subsequently, the evaluation team (the remaining 10 authors) investigated the viability of these models. Results: The evaluation team determined that abdominal pattern models matched to the following typical Kampo formulas were created successfully: Dai-saiko-To (), Dai-joki-To (), Shigyaku-San (), Saiko-ka-ryukotsu-borei-To (), Keishi-bukuryo-Gan (), Hachimi-jio-Gan (), Hange-shashin-To (), Sho-saiko-To (), Hochu-ekki-To (), Sho-kenchu-To (), Toki-shakuyaku-San (), Ninjin-To (), and Dai-kenchu-To (). Conclusion: We suggest that these new formula-pattern models can make an important contribution to the standardization of abdominal diagnosis and prescription and to Kampo education.

Effects of the herbal medicine composition "Saiko-ka-ryukotsu-borei-To" on the function of endothelial progenitor cells in hypertensive rats.

Endothelial progenitor cells (EPCs) are known to repair vascular injuries. Recent studies suggest that Saiko-ka-ryukotsu-borei-To (SKRBT), a traditional herbal medicine that has been used to treat stress-related neuropsychiatric disorders, has protective effects on cardiovascular diseases such as hypertension and arteriosclerosis. Spontaneously hypertensive rats (SHRs) were fed diets containing lyophilized SKRBT extract for 6 weeks. Peripheral blood mononuclear cells (MNCs) were isolated and cultured to assay EPC colony formation. Oxidative stress in MNCs was evaluated by thiobarbituric acid reactive substance (TBARS) assay and flowcytometric analyses. Treatment with SKRBT increased EPC colony numbers significantly (p<0.05) with decrease in oxidative stress and without affecting blood pressure in SHRs. Treatment with SKRBT did not reduce the expression of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase subunits in cardiovascular organs. Serum IL-6 level was significantly reduced. SKRBT is a feasible herbal medicine that protects against cardiovascular diseases through an increase in EPC function along with anti-oxidative effects, and may affect the link between chronic inflammation and cardiovascular disease.

Prolonged survival of fully mismatched cardiac allografts and generation of regulatory cells by Sairei-to, a Japanese herbal medicine.

Sairei-to (TJ114), a 12-component Japanese herbal medicine, is used to treat immune-related diseases. We investigated the effects of oral administration of TJ114 in a murine model of cardiac transplantation with fully mismatched allografts. Untreated CBA mice rejected C57BL/6 hearts acutely (median survival time [MST], 7 days), whereas survival of allografts from mice given TJ114 was significantly prolonged (MST >100 days). Secondary CBA recipients of C57BL/6 hearts also had prolonged allograft survival (MST >100 days) after adoptive transfer of whole or CD4 splenocytes from primary CBA allograft recipients given TJ114. None of the individual components of TJ114 prolonged allograft survival, suggesting that its effects require administration of the combination agent. In mixed leukocyte cultures, proliferation of splenocytes from TJ114-treated CBA recipients was markedly suppressed compared with that of splenocytes from untreated mice, and interferon-gamma production was significantly reduced. Thus, in our model, TJ114 treatment induced hyporesponsiveness to cardiac allografts and generated CD4 regulatory cells.
