In recent years, expectations and demand for Japanese Kampo medicines have increased in Japan. However, the self-sufficiency rate of raw materials for crude drugs in Japan is approximately 10%, with most imported from China. Although discussions on the domestic production of raw materials are gaining momentum, achieving self-sufficiency of crude drugs for Kampo preparation poses several challenges, including production costs, sales channels, and distribution prices. However, it is well-known that a diverse array of crude drugs can be cultivated in the Japanese climate. Since 2013, Ibara City in Okayama Prefecture has been promoting a medicinal plant cultivation project to utilize fallow land effectively. Currently, we have achieved successful cultivation of ‘benishizuka,’ a medicinal peony known as Paeoniae radix, with sufficient quality. However, the present circumstances in Japan limit its sales channels for medical use. The project initiated by Ibara City has evolved from its inception, primarily involving farmers, the government, and national research institutes, to now encompass an unprecedented collaboration among medical professionals as well as local construction companies and a local university. This transformation has propelled Ibara City’s various new medicinal plant cultivation businesses into a new phase of development. In this report, we investigated the local history and climate from the perspective of a Kampo medicine practitioners and discuss the path to successful peony cultivation. Additionally, we delve into the innovations and outcomes pertaining to peony cultivation. Moreover, we report the challenges and prospects for the domestic production of crude drugs for Kampo preparation from the perspective of multiple professions.

The aim of this study is to clarify the diet and complementary and alternative medicine among terminal cancer patients followed at home. A cross-sectional survey of bereaved families of 200 cancer patients who were received home care by 5 palliative care clinics in Kobe in 2014. The response rate was 66％. The average age of the patients was 74 years old. The family members received the information about diets from books, magazines, and newspaper（48％）and medical staff（46％）. The patients actively took in tea（64％）, dairy（62％）, and soy（60％）. The patient avoided alcohol（49％）, fat（31％）, and salt（31％）. The question asking the complementary and alternative medicine（CAM）, 32％ respondents answered using CAM, of which 28％ took mineral supplements, and vitamins. Due to the paucity of the evidence about the diet and CAM for cancer patients, the patient and family tend to practice the general diet therapy.

The aim of this study was to clarify diet and meal preparation for terminal cancer patients followed at home. A cross-sectional survey was administered to bereaved caregivers of 200 cancer patients who received home care from five palliative care clinics in Kobe in 2014. The response rate was 66% and the average age of the caregivers was 62 years. Overall, 57% of caregivers reported distress regarding diet and meal preparation for patients. The independent determinants of distress were: the experience of coaching from medical staff （P=0.012）; how to help patients with eating; difficulties in cooking and meal preparation （P=0.001）; and helping with eating for anorexic patients （P=0.004）. Due to the paucity of the evidence about diet and meal preparation for cancer patients, caregivers may not be receiving sufficient specific and practical dietary instruction from medical staff.

OBJECTIVESTo investigate the effect of snack eating on salivary cortisol and chromogranin A (CgA).

METHODSFrom 14∶00 to 18∶00, starting two hours after consumption of a midday meal, saliva samples were collected every 30 minutes from 15 healthy males, 7 of whom (snack group) ate a snack immediately after the sampling at 15∶00. Salivary cortisol and CgA levels were determined by ELISA. Samples were controlled according to salivary flow rates.

RESULTSFor the snack group, after snack consumption, salivary cortisol increased to exceed significance (p<0.05) at 15∶30 and rose even higher at 16∶00. In the control group, there was no such change. There was no significant change in salivary CgA in either the snack group or the control groups during the sampling period.

CONCLUSIONSThese findings suggest that no food should be consumed for at least 90 mins before saliva sampling for cortisol determination and that salivary CgA is probably not affected by snack eating.

OBJECTIVESTo use the evaluation of a specific brain function obtained by optical topography. This system uses a non invasive method to measure brain function unlike other major systems.

METHODSTwelve optical fibers were attached to the subject's head. Hemodynamic changes in the motor cortex were measured during finger tapping before and after alcohol intake for eachALDH2 genotype.

RESULTSDifferent hemodynamic changes in the motor cortex were observed among, theALDH2 genotypes.

CONCLUSIONSOptical topography is a useful tool for evaluating specific brain functions. Further research is needed on the relations between various environmental factors and brain functions by optical topography.

OBJECTIVESThe purpose of this study was to investigate the effect of tomato juice drinking on the antimutagenicity of saliva.

METHODSSubjects were 22 healthy male university students. They were divided into tomato group and control group. The tomato group drank tomato juice for 10 days. The anti-mutagenicity of saliva was measured using the umu test.

RESULTSIn the tomato group, there was a significant increase in the inhibiting capacity of saliva on the mutagenicity of AF-2 after tomato juice drinking for 10 days. This increase was, however, temporary. In the control group, there was no such change in the inhibiting capacity of saliva.

CONCLUSIONSThese findings suggest the significant effect of tomato juice drinking on the anti-mutagenicity of saliva. In addition, lycopene may have played an important role in its mechanism.

OBJECTIVESBlood and saliva samples were obtained to examine if there is a correlation between saliva glycated protein and blood glycated protein.

METHODSBlood and saliva samples of 51 male workers were collected. The fructosamine and hydrazine methods were used to measure saliva glycated protein. HbA1c, fructosamine and blood glucose were measured as indices of blood glycated protein, and the correlation between blood glycated protein and saliva glycated protein was examined.

RESULTSSaliva fructosamine glycated protein showed a significant correlation with HbA1c and blood glucose (r=0.449; p=0.001 and r=0.445; p=0.001, respectively). No correlation was identified between saliva hydrazine glycated protein and the index of blood glycated protein.

CONCLUSIONSBlood glycated protein and blood glucose could be estimated by measuring saliva glycated protein.

OBJECTIVESThe purpose of this study was to compare the anti-mutagenicity of Salivette and test-tube sampling saliva. In addition, the relation between the inhibiting and pH-buffering capacities of saliva was investigated.

METHODSSubjects were 52 healthy female university students. The collection of saliva samples was carried out using 2 sampling devices; test-tube and Salivette. The anti-mutegenicity of the saliva was measured using the umu test.

RESULTSThe inhibiting capacity of Salivette-saliva was significantly lower compared with that of testube-saliva (p<0.01,t test). However, there was a significant correlation between them (r=0.35; p<0.05). In addition, there was a significant correlation between the inhibiting and pH-buffering capacities of saliva (r=-0.36; p<0.05).

CONCLUSIONSThese findings suggest that both the Salivette and the test-tube may be appropriate as saliva-sampling devices. In addition, they suggest that the bicarbonates might inhibit the anti-mutagenicity of saliva, or that the activity of substances related to the anti-mutagenicity of saliva might be dependent on pH.

OBJECTIVESThe purpose of this study was to investigate the relation between lifestyle and the antimutagenicity of saliva.

METHODSSubjects were 52 healthy female university students. The collection of the saliva samples and the lifestyle measurements were carried out for them. The anti-mutagenicity of the saliva was measured using the umu test.

RESULTSWith regard to the lifestyle items, only "nutrient balance" tended to contribute positively to the inhibiting capacity of the saliva on the mutagenicity of AF-2. In addition, there was a significant inverse correlation between the score of 7 other items and the inhibiting capacity of the saliva (r=-0.32; p<0.05). We also found a significant relation between their tea and/or coffee consumption and the inhibiting capacity of the saliva.

CONCLUSIONSThese findings suggest that the inhibiting capacity of saliva worked to decrease mutagen levels that were enhanced by poor lifestyle. In addition, "nutrient balance" may contribute to the inhibiting capacity of the saliva independent of 7 other items. With regard to the tea and/or coffee consumption. further studies should be carried out.
