Young green barley leaves are a good natural source of vitamins and minerals, and their juice is widely consumed as a functional food for(More)
The chemokine interleukin-8 (IL-8) is involved in the pathogenesis of acute lung injury (ALI). Although several studies have reported that 1α,25-dihydroxyvitamin D(3) (1α,25(OH)(2)D(3)) suppresses IL-8 production in vitro and in vivo, 1α,25(OH)(2)D(3) has not been demonstrated to be effective in an animal model of ALI. Here, we determined its effects of(More)
BACKGROUND Bilberry (Vaccinium myrtillus L.) is one of the richest sources of anthocyanins which are known to have anticancer, wound healing and anti-allergic effects. Here, we examined whether bilberry extract (Bilberon-25) alleviates pruritus in a mouse model of chronic allergic contact dermatitis. MATERIALS AND METHODS BALB/c mice with chronic allergic(More)
BACKGROUND Young green barley leaf is one of the richest sources of antioxidants and has been widely consumed for health management in Japan. In this study, we examined whether oral administration of young green barley leaf has an antidepressant effect on the forced swimming test in mice. MATERIALS AND METHODS Mice were individually forced to swim in an(More)
BACKGROUND Goldenseal (Hydrastis canadensis L.) inhibits various cytochrome P450 (CYP) isoforms such as CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A in vitro. High doses of acetaminophen (APAP) generate the highly reactive intermediate, N-acetyl-p-benzoquinone imine (NAPQI), catalyzed mainly by CYP2E1. The aim of this study was to investigate the(More)
While searching for vitamin D(3) analogues which inhibit neutrophil recruitment in the lung without elevating plasma calcium level, we found that (5Z,7E)-(1S,3R)-20(R)-[(5E)-(2S)-2-hydroxy-2-methyl-cyclopentanone-5-ylidene]methyl-9,10-secopregna-5,7,10(19)-triene-1,3-diol (TEI-A00114) had the best efficacy and calcemic action. TEI-A00114 has a vitamin D(More)

The gender aspect in pharmacokinetics and pharmacodynamics of anesthetics has attracted little attention. Knowledge of previous work is required to decide if gender-based differences in clinical is justified. Females have 20-30% greater sensitivity to the muscle relaxant effects of vecuronium and rocuronium. When rapid onset of or short duration of action(More)
Keishibukuryogan (KBG; Guizhi-Fuling-Wan in Chinese) is one of the Kampo (Japanese traditional) medicines used to treat patients with climacteric syndrome. KBG can be used by patients who cannot undergo hormone replacement therapy due to a history of breast cancer. We evaluated whether cytosine-adenine (CA) repeat polymorphism of the estrogen receptor β(More)

BACKGROUND Citrus natsudaidai (natsumikan) is a typical citrus fruit containing several antioxidative nutrients which are found in higher concentration in the peel than in the pulp of the fruit. In this study, we examined whether extract from immature natsumikan peel prevents development of chronic allergic dermatitis in mice. MATERIALS AND METHODS(More)
