With the cooperation of Kurobe City, we conducted a basic survey using the nine classification of constitution and an intervention survey using a constitutional guidance program. The basic survey was conducted by the Kurobe group (Kurobe River alluvial fan spring water drinker n=155, 60.6±10.4 years old) and the non-Kurobe group (normal tap water drinker n=99, 50.7±12.8 living in the Hokuriku region without Kurobe City). A total of three surveys were conducted using the constitution Questionnaire (CCMQ-J). As a result, the Gentleness type, which is usually called the healthy constitution, was clearly higher in the Kurobe group, with 44.6 % in the Kurobe group and 22.5 % in the non-Kurobe group. In the proportion of each biased constitution(Mibyo constitution), the Kurobe group had less Wet-heat type (4.5 % vs 11.8 %), Qi-depression type (5.4 % vs 10.7 %), Yin-deficiency type (7.1 % vs 12.3 %) , and Phlegm-wetness type (5.8 % vs 9.6 %) than the non-Kurobe group. After the basic survey was completed, the Kurobe group was randomly divided into two groups, an intervention group (n=65, 62.3±9.3 years old) and a non-intervention group (n=68, 62.7±9.8 years old), and compared with the non-Kurobe group (control group) (n=80, 51.9±13.6 years old). The survey design was a simple comparative study, and the primary endpoint was a comparative study of changes in constitutional scores before and after intervention. As a result, in the Yang-deficiency type, a significant difference was observed between the intervention group, the non-intervention group and the control group at the first time after the intervention (One-way ANOVA p=0.04). No change was seen in the second survey after the intervention. In the comparison of Phlegm-wetness type between the three groups, there was a tendency in the amount of change in the constitutional score (One-way ANOVA p=0.087). From the above, it was suggested that the constitutional survey can not only grasp the health and the pre-symptomatic state, but also improve the pre-symptomatic by combining the guidance methods according to the constitution.

We evaluated the effect of Coix-seed Reactive Derivatives (CRD) on cold sensitivity of female hands and feet. Ninety females were assigned randomly to 3 groups and CRD(2g/day, 4g/day or placebo) was administrated for 8weeks. Significant improvement of cold sensitivity was observed in both the 2g/day and 4g/day groups. It was speculated that a naringenin and a quercetin as active ingredients of adlay hull may play a critical role in ameliorating effect on blood flow.

To clarify the functions of Coix-seed Reactive Derivatives(CRD), we observed 2 cases of plantar keratosis (case 1. 34 years of age, female/ case 2. 29 years of age, female) successfully cured by intake of CRD for several months. Although CRD intake seemed to be effective in these cases, further studies are needed to define the optimal dose and duration.

To clarify the functions of Coix-seed Reactive Derivatives(CRD), we observed 3 cases of refractory atopic dermatitis(case 1. 25 years of age, male/ case 2. 40 years of age, female/ case 3. 5 years of age, male) successfully cured by intake of CRD. Although CRD intake seemed to be effective in all cases, further studies are needed to define the optimal dose and duration.

To clarify the functions of Coix-seed Reactive Derivatives(CRD), we observed 2 cases of plantar wart (case 1. 8 years of age, female/ case 2. 26 years of age, female) successfully cured by intake of CRD for several months. Although CRD intake seemed to be effective in these cases, further studies are needed to define the optimal dose and duration.

In this report, we presented the case of a 45-year-old man who developed intractable eczema on the thumb-index interdigital fold for over 3 years. Coix-seed Reactive Derivatives(CRD) was administrated at a dose of 2.2g/day per day. The lesion cured markedly within 7 months. Although CRD intake seemed to be effective in this case, further studies are needed to define the optimal dose of this food.

Chinese Medicine Questionnaire (CCMQ-J) consists of sixty independent questionnaires and 9 physical constitutions called subscales. One type is balanced constitution (i.e., gentleness), and the following eight types represent unbalanced constitution: Qi-deficiency constitution, Yang-deficiency constitution, Yin-deficiency constitution, Phlegm-dampness constitution, Damp-heat constitution, Stagnant Blood constitution, Stagnant Qi constitution, and Inherited Special constitution. In this study, we proposed to determine optimal number of groups in 851 participants recruited from crowdsourcing answered CCMQ-J questionnaire consisting of 60 questions. In the present study, we applied k-means clustering with gap statistics to the questionnaire data and the number of optimal groups was estimated by five. The five groups are mainly characterized by 3 subscales in CCMQ-J, i.e. (i) two subscales corresponding to Yang-deficiency and Qi-depress, (ii) three subscales corresponding to gentleness, Yang-deficiency and Qi-depress (iii) Yang-deficiency, (iv) gentleness, and (v) Qi-depress. In the crowdsourcing survey, two subscales, Yang-deficient and Qi-depress are the most frequently occurred in current Japanese people.

Objective: In this study, we evaluated the safety of intake of Coix-seed Reactive Derivatives (CRD) in healthy adult volunteers.Methods: Eight subjects (4 males and 4 females, ages 26.6 ± 4.7) consumed 2.0g CRD/day for 4weeks. We observed weight, vital signs(blood pressure, pulse, body temperature), complete blood count(red blood cell count, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, white blood cell count, and platelet count), hemogram, blood chemistry(Na, K, Cl, AST, ALT, γ-GTP, LDH, ALP, total protein, albumin, A/G, total bilirubin, urea nitrogen, creatinine, cholinesterase, total cholesterol, HDL cholesterol, LDL cholesterol, and neutral fats), coagulation examination (prothrombin time and partial prothrombin time), and urinalysis (sugar, protein, and occult blood in urine).Results: Although several laboratory data (MCHC, MCV and serum creatinine) changed slightly, all of these values were within normal range. Furthermore, no severe adverse effect was observed.　Conclusion: These results suggest that CRD intake up to 2g/day is safe in healthy adults. Further study will be needed to define the safety of long-term administration of CRD.

To clarify the functions of Coix Reactive Derivatives(CRD), we observed 4 cases of refractory acne vulgaris (case 1. 20 years of age, male/ case 2. 46 years of age, female/ case 3. 20 years of age, male /case 4. 28 years of age, female) successfully cured by intake of CRD for several months. Although CRD intake seemed to be effective in all cases, further studies are needed to define the optimal dose and duration.

Purpose: An open-label, single-arm study was conducted to evaluate the effectiveness of porcine placental extract (PPE) ingestion to improve late-onset hypogonadism (LOH) syndrome symptoms. In addition, we reported the safety of continuous PPE ingestion in biochemistry tests.Materials and Methods: Test food containing PPE was given daily to healthy male subjects with an Aging Males’ Symptoms (AMS) score of ≥27, who were assessed as having LOH syndrome. AMS score, blood hormone level, and other parameters were measured before the start of PPE ingestion, Week 4, and Week 8. And adverse events that occurred during the ingestion period were accumulated.Results: Excluding one subject who withdrew from the study due to an adverse event unrelated to the test food, 14 subjects were included in the analysis. In terms of AMS score, no improvement was observed at Week 4, whereas a significant improvement was observed at Week 8. AMS scores were further categorized into three subscales (psychological, somatic, and sexual) and analyzed. The results showed a significant improvement from baseline in somatic scores at Week 8. Meanwhile, no significant change in sexual hormone levels was observed. At Week 8, improvements from baseline were observed in renal function and LDL cholesterol level. There were no adverse events related to the test food.Conclusion: The study demonstrated that 8-week PPE ingestion in middle-aged and elderly men can improve LOH syndrome symptoms while having little effect on sexual hormone secretion.
