This study was aimed to evaluate the inhibitory effect of astaxanthin on 7 types of CYP enzymes (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6 and CYP3A4) by using human liver microsomes and to evaluate the inducing effect of astaxanthin on 3 types of CYP (CYP1A2, CYP2B6 and CYP3A4) by using cryopreserved human hepatocytes.Resuts indicated that astaxanthin does not inhibit CYP enzymes within the normal doses and astaxanthin does not induce CYP enzymes within the normal doses.

Safety and effectiveness of powered food made from Agaricus blazei Murill was evaluated by a randomized human study. 45 healthy subjects were divided into 3 groups in sequence: control, 1 pack and 3 packs/day-administered groups. Each group had 15 persons. They had each packs for 28 days, and followed, in every two weeks, by the evaluation with CTCAE v3.0, QOL (SF36-v2), and biochemical examinations including liver/lung/kidney function, insulin resistance and NK activity and high-sensitivity CRP. None of them had adverse events nor biochemical/lung abnormal examinations. 1 and 3 packs-administered groups improved their QOL, high-sensitivity CRP and NK activity in a dose-dependent manner. These results ascertained safety, and effectiveness of the powdered food made from Agaricus blazei Murill against presymptomatic disorders including metabolic syndrome.

The purpose of this study was to examine the health-related Quality of Life (QOL) of women and the effects of “fruits granola” on women’s health. It was based on an Internet questionnaire survey on QOL (using a QOL questionnaire for women that was prepared by LSTT Co., Ltd.) of 3,460 subjects who answered questions concerning physical and mental matters. It also had 165 subjects, 108 of whom had mild constipation and 57 of whom did not, consume fruits granola freely for a period of time and then compared their QOL before and after consumption.The results of the screening survey showed significantly higher scores in all categories among women who did not have constipation than women who did. Additionally, the mental QOL score was significantly higher among women who had the habit of eating fruits granola.Moreover, the overall QOL score significantly increased after consumption of fruits granola. These results suggest that consumption of fruits granola may be effective in improving women’s QOL.

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.

Although introduced to Japan as a health food, Huaier granule emerged with abundant evidence, both from fundamental and clinical researches, and is being prescribed clinically in China, since it was originally developed as a new pharmaceutical. Huaier granule has a wide range of application and this review narrow down to the effects of it to hepatocellular carcinoma, the most reported one.

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.

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.

In order to investigate the effects of fruits granola intake on defecation and quality of life (QOL), 20 females (mean age: 20.0 ± 1.1 y.o.) with frequency of defecation of less than 5 times per week were selected for this open study. Daily intake of 50 g of fruits granola was used as a substitute staple food for 2 weeks, and changes in defecation and QOL were compared before and after the procedure. The results showed that, compared with the pre-intake period, the frequency of defecation and the amount of defecation increased after fruits granola intake (p = 0.014, p = 0.024), and improvement of QOL (p = 0.011) was also observed. We conclude that, a continuous intake of fruits granola can improve defecation, and also improve quality of life.

Objective: We examined anti-influenza virus (anti-IFV) activity of Coix-seed Reactive Derivatives (CRD) extract.Methods: H1N1 A/Puerto Rico/8/34 (PR8) strain was infected to Malin Darby Canine Kidney (MDCK) cells. The infected cells were cultured by medium supplemented CRD extract for 24 h, and the supernatants were harvested to analyze virus titer by focus-forming reduction assay. Polyphenols were removed by PVPP treatment, and anti-influenza virus activity was compared with normal CRD extract. Results: CRD extract showed anti-IFV activity. In addition, CRD extract inhibited viral adsorption and replication. The study of CRD extract by PVPP treatment suggested that polyphenols are the main active component. Conclusion: This study revealed that CRD extract has anti-IFV activity against PR8 strain. The mechanism of action was inhibited viral adsorption and replication. It was also suggested that anti-IFV activity of CRD extract is due to polyphenols.
