Background: Adlay (Coix lacryma-jobi L. var. ma-yuen Stapf) has been used both in traditional Chinese medicine and as a nourishing food based on its unique biological effects and highly nutritional values. In the present study, we investigated the anti-tumor effect of a hot-water adlay extract in sarcoma mice model. Materials and Methods: The hot water extract of whole adlay was orally administered to mice for one week, after which Sarcoma-180 cells (1×106) were subcutaneously implanted into the abdomen. Thereafter, the tumor growth was monitored and mouse survival was examined. Results: Tumor weights measured at 18 days were significantly lower in mice treated with extract (100 and 300 mg/kg/day) than those in control group (p<0.01). Moreover, mice treated with extract (100 mg/kg/day) showed apparently longer survival than control group evaluated until 32 days (p<0.05). Conclusion: These findings indicate that hot water adlay extract appears to have some anti-tumor effects in vivo insarcoma cells.

On the study of polyphenols from Fragaria ananassa fruit, we reported that some polyphenols showed inhibition of metabolic enzyme, cytochrome P450. Continuous study of health effects of F. ananassa fruit, we isolated a new quercetin glycoside, flagarin, quercetin-3-O- β-glucuronyl- (2→1)- β-D-xyloside along with ten known compounds. Those compounds showed inhibitory activity of fat accumulation in rat white adipocyte. Among the isolated compounds, strictinin and the new compound, flagarin showed high inhibitory activity of fat accumulation in rat white adipocyte.

CRD, a Coix-seed Reactive Derivatives, has a novel mechanism in the treatment of various diseases. In the present study, a fluorometric-based high throughput method using cytochrome P450 (CYP)screening kit was adopted to evaluate in vitro inhibition potential of CRD (CRD 1 and CRD 2) on CYP isoenzymes by calculating remaining enzyme activities and inhibitory potential (IC50 values) using the determined values of fluorescence intensity. IC50 of CRD 1 and CRD 2 were as follows: CYP3A4; >500 µg/ml, 490 µg/ml, CYP2D6; >500 µg/ml,>500 µg/ml,CYP2C9; >500 µg/ml,339 µg/ml, respectively. The result showed that CRD exhibited little activity in the inhibition of CYP3A4, CYP2D6 and CYP2C9.

Objectives: The aim of this study is to examine the effects of lactic fermenting beverage ANP71 on defecation, blood pressure, immune function, constitution of Traditional Chinese Medicine (TCM) and safety.Methods: An open Clinical study was conducted on 15 healthy adults (female 11, male 4). ANP71 150ml per day was administrated for 4 weeks. At week 0, 1 and 4, blood samples were collected. blood pressure, immune function and constitutionwere measured.Results:① Defecation amount and exhilarating feeling increased. Abdominal feeling of fullness decreased.② Decrease of blood pressure was observed. ③ The change of parameters of blood biochemistry was in normal range. ④ Humoral immunity was predominant(Th1/Th2 decreased). ⑤ In constitution of TCM, Gentleness type, Yang-deficiency type, Yin-deficiency type, Phlegm-wetness type, wet-heat type and Qi-depression type were improved. ⑥ No significant adverse events were observed.Conclusion: Lactic fermenting beverage ANP71 appears to have benefits in improving defecation and constitutional problems. Various other biological effects of ANP71 were also observed.

Extract of Lentinula edodes mycelia (LEM) reportedly maintains and improves the quality of life (QOL) of patients with cancer who undergo chemotherapy. We investigated the influence of LEM extract on the QOL of 73 Japanese patients with different backgrounds and stages of cancer who were undergoing various types of therapy at 16 institutions. All patients were orally administered with LEM (1200 mg/day) for four weeks. We compared changes in their QOL before and after taking LEM using the EORTC-QLQ-C30. The QOL scores for emotional function and fatigue were significantly improved after LEM intake. Global QOL and physical function scores improved only in patients with cancer at stages III and IV. These findings suggest that oral LEM intake improves the QOL of patients with advanced cancer.

Japanese version of the Constitution in Chinese Medicine Questionnaire (CCMQ-J) in Chinese consists of 60 items for 9 sub-scales called Gentleness, Qi-deficiency, Yang-deficiency, Yin-deficiency, Phlegm-wetness, Wet-heat, Blood-stasis, Qi-depression, and Special diathesis. Each question is answered by choosing one form 5 grades of a Likert scale where the grades from 1 to 5 corresponding to Never, Rarely, Sometimes, Often and Always, respectively. In the present study, we examined the relationship of scores based on 597 respondents to 60 items. We tentatively classified 60 items into 12 groups by utilizing the Ward’s hierarchical clustering method and discussed similarity of items and 9 body conditions. Body Mass Index (BMI) and age can be explained by the score of 60 items by partial least square model. Significantly high correlation coefficients between real and estimated values were obtained for BMI (0.81 for male and 0.82 for female) and age (0.82 for male and 0.83 for female). Those results indicate that the answers to the 60 items can reflect aging and BMI properties and CCMQ-J can be used to assess the situation of health for evaluating the actual aging conditions in human.

Objectives: To study the effect of astaxanthin contained drink to skin conditionMethod: The study was conducted to the Japanese females between age over thirty to less than fifty , who had weakening of skin (including aging, sag and dry skin) and skin dullness. In order to conduct the objective evaluation, the comparison between the groups by the double-blind test was taken. Twenty of subjects were randomly allocated to the intake group of astaxanthin contained drink (astaxanthin 3mg contained) and the placebo group. After eight weeks intake of the drink, each group was evaluated with skin water contents, transepidermal water loss, skin elasticity, VISIA and skin texture etc.Result: In between the groups, the intake group of astaxanthin contained drink was greatly excellent in the categories of skin moisture, transepidermal water loss, skin elasticity , erythema dose and skin texture.Conclusion:Astaxanthin has protecting effect of skin barrier and is considered to increase the water retention capability to reduce skin dryness. Astaxanthin is also effective to erythema dose, skin elasticity and skin texture. As no adverse events resulting from the test drink was seen, such food containing astaxanthin is considered as a safe and useful health functional food material to skin.

Kaempferia parviflora rhizome is used in traditional folk medicines for the treatments of various symptoms in Thailand since ancient times. Several types of methoxyflavones were identified from that plant and the functions of some of those were reported. We determined that five kinds of methoxyflavones (5-hydroxy-3,7,3’,4’-tetramethoxyflavone, 5-hydroxy-7-methoxyflavone, 5-hydroxy-3,7-dimethoxyflavone, 5-hydroxy-3,7,4’-trimethoxyflavone, 5-hydroxy-7,4’-dimethoxyflavone) were included the following treatments of K. parviflora rhizome. The 80 %ethanol extract of that were adsorbed resin, removed 70 % ethanol elution and the rest adsorbed materials were eluted with 99.5 % ethanol. The safety of that five methoxyflavones mixture was evaluated. We performed a 28-day repeated dose of oral toxicity test and a mouse micronucleus test. The former results showed no significant toxicity on body weight, blood analyses, organ weight, blood biochemical analyses. The latter results showed negative, believed that the sample has no mutagenicity for living bodies.
