A relationship has been reported between trace elements and diabetes mellitus. This study examined the concentration of several trace elements (Zn, Mg, Ca, Fe, Cu, Mn, P) in each organ from spontaneous type 2 diabetic model rat (GK rat) and compared with control. Results showed that diabetic rat excreted 1.25-, 1.5-fold more zinc and magnesium,(More)
In the three-dimensional structure of a rice class I chitinase (OsChia1b) determined recently, a loop structure (loop II) is located at the end of the substrate-binding cleft, and is thus suggested to be involved in substrate binding. In order to test this assumption, deletion of the loop II region from the catalytic domain of OsChia1b and replacement of(More)
Oseltamivir phosphate (Tamiflu), an anti-influenza virus drug, is hydrolyzed by carboxylesterase to an active metabolite. The metabolite inhibits the influenza virus-specific neuraminidase. In this study, the effects of oseltamivir on normal core body temperature were studied in mice. Oseltamivir (30-300 mg/kg, intraperitoneally (i.p.) and 100-1000 mg/kg,(More)
PURPOSE The purposes of this study were: (1) to assess the therapeutic and side effects of influenza vaccination during a winter season by comparison of vaccinated and non-vaccinated subjects; and (2) to survey their willingness to receive vaccination in the future based on their experience with the present vaccination. METHOD The subjects were 185(More)
We investigated the association between nutrient biomarkers and dietary intake estimated using a brief self-administered dietary history questionnaire (BDHQ) for Japanese children and adolescents. Blood samples were collected from 398 subjects (5th graders of elementary school aged 10-11 y, and 2nd graders of secondary schools aged 13-14 y) randomly(More)
BACKGROUND Cutoffs based on percentage overweight (POW) are used for screening students in Japan; however, body mass index (BMI) is more common in the rest of the world. To screen for risk factors related to obesity among Japanese primary and secondary school students, we compared fasting and postprandial values, and the receiver operating characteristic(More)
OBJECTIVES To investigate breakfast eating habits on daily energy and fish, vegetable, and fruit intake in Japanese adolescents. METHODS This study was completed as part of the Shunan Child Health Cohort Study. Two types of questionnaires, one on lifestyle habits and the other a brief-type, self-administered questionnaire on diet history, were(More)
The effect of triptolide, which is isolated from Tripterygium Wilfordii, on induction and development of murine AA amyloidosis was studied. In the first experiment, we examined the ability of triptolide to inhibit initiation of amyloidosis. Oral or intraperitoneal administration of 480 microg/kg/day triptolide inhibited splenic amyloid deposition in both(More)
The present study assessed whether serum carotenoids and tocopherols are associated with atopic diseases (eczema and asthma) in 10- and 13-yr-olds in a Japanese community. Of 2796 students attending schools in Shunan, Japan, in 2006, 396 students were randomly selected for this study using nested case-control design. Atopic diseases and dietary food intake(More)
BACKGROUND The effects of fish consumption and n-3 poly-unsaturated fatty acid (PUFA) levels on atopic disorders are inconsistent in previous reports, but few studies have investigated the effects of both fish and n-3 PUFA. The aim of the present study was to investigate whether erythrocyte fatty acids and the consumption of fish are associated with atopic(More)
