BACKGROUND: It is very important for the late-stage elderly to have the least stressful bowel movements for maintaining a good quality of life. It is generally accepted that consuming adequate dietary fiber is a promising method for the prevention and management of stressful bowel movements such as those during constipation. Therefore, we examined the effect of long-term consumption of waxy barley, which is high in dietary fiber, on the bowel movements of the late-stage elderly living at Roken nursing home (a geriatric health services facility), Japan.METHODS: We compared the defecation and laxative administration frequencies of the subjects before and after waxy barley consumption, for which we served 28 residents a boiled mixture of rice and waxy barley (variety name, Kirarimochi) as the main meals for 5 months, from November to March. In October, all residents were served boiled rice as the main meals.RESULTS: The residents were categorized into "constipated" subjects and "non-constipated" subjects according to their weekly defecation frequency during October. Among the 14 residents categorized as constipated subjects, monthly number of days with defecation in November, January, and March significantly increased in comparison to monthly number of days with defecation in October. In addition, monthly number of days with laxative administration significantly decreased in December and February in comparison to monthly number of days with laxative administration in October. In contrast, the defecation and laxative administration frequencies did not change after waxy barley consumption among the 14 residents categorized as non-constipated subjects.CONCLUSIONS: Consumption of waxy barley, Kirarimochi, for 5 months improved the bowel movements of the constipated subjects; however, the consumption had no effect on the bowel movements of the non-constipated subjects at Roken nursing home. These results indicate that consuming waxy barley, Kirarimochi, is beneficial for the management of constipation in the late-stage elderly residents at Roken nursing home.

Ethnopharmacological relevance: Tryptanthrin is a compound isolated from Polygonum tinctorium, which is a known folk medicine with various biological activities. Aim of the study: Allergic diseases are initiated by the development of allergen-specific T helper type 2 (Th2) cells and amplified by the degranulation of and cytokine release from basophils and mast cells during an effector phase. We found that Tryptanthrin could down-regulate IL-4 production by Th2 cells, while IFN-γ production by Th1 cells was not affected. Since IL-4 produced by basophils and effector Th2 cells has been shown to play important roles in the development and amplification of Th2-dominated allergic responses, we examined the effects of Tryptanthrin on the initiation and effector phase responses of Type I allergy in vitro. Materials and methods: To determine the mechanisms of Tryptanthrin-induced down-regulation of IL-4 production, the expression of Th2-specific transcription factors, c-Maf and GATA-3, was analyzed by RT-PCR. The effects of Tryptanthrin on Th cell differentiation were evaluated using CD4+ T cells purified from spleen cells of Sugi basic protein (SBP)-immunized BALB/c mice. In primary cultures, cells were stimulated with SBP and antigen-presenting cells under neutral or Th2-skewing conditions in the presence or absence of Tryptanthrin. Cytokines produced by differentiated Th cells in secondary cultures were analyzed by ELISA. The effects of Tryptanthrin on IgE-mediated degranulation and IL-4 production were determined using rat basophilic leukemia (RBL-2H3) cells. Phosphorylation of ERK1/2 and Akt in Tryptanthrin-treated RBL-2H3 cells was analyzed to determine the mechanism of Tryptanthrin actions. Results: Tryptanthrin suppressed c-Maf mRNA expression in Th2 clone cells, and even under Th2-skewing conditions, Tryptanthrin inhibited differentiation toward the Th2 phenotype, which is an essential event for the initiation phase of allergic diseases. Tryptanthrin also inhibited the IgE-mediated degranulation of and IL-4 production by RBL-2H3 cells, probably due to inhibiting IgE-mediated signaling pathways, including the phosphorylation of ERK1/2 and Akt. Conclusion: These findings suggest that Tryptanthrin effectively inhibits the effector and exacerbation responses, as well as the initiator responses, of Type I allergy. Thus, Tryptanthrin may have beneficial effects for immediate-type allergic responses. © 2011 Elsevier Ireland Ltd.

Objective: The purpose of the present pilot study was to investigate the link between diet and mental health in female university students enrolled in a training course for registered dietitians. Subjects and methods: A total of 62 female university students, with a mean age of 18.79 ± 0.45 years, participated in this cross-sectional study. Diet surveys were performed using the brief-type self-administered diet history questionnaire (BDHQ). Mental health was also evaluated using the general health questionnaire-12 (GHQ-12), which was the shortest form and clinically available. Lifestyles such as physical activity levels were also evaluated. Results: The mean energy intake was 1379 ± 575 kcal and the mean GHQ score was 3.11 ± 2.41. Among nutrients, vegetable fat and sucrose showed a weak positive correlation with the GHQ scores. Among food groups, potatoes, fats and oils, and confectioneries also showed a weak positive correlation with the GHQ scores. A multiple regression analysis showed that the confectioneries were the determining factor for the GHQ scores. Conclusion: Proper education concerning their diets and reducing confectioneries in their daily lives might be beneficial for the mental health of female university students. © 2016 The Japanese Society for Hygiene

Objective: The aim of this study was to investigate the linkage among ambulance transports, the number of death and air temperature in Takamatsu area, Japan. Methods: Monthly data of ambulance transports (total and acute disease) and the number of death from 2004 to 2012 were obtained from Fire Department Service in Takamatsu and Takamatsu city official website, Japan. Climate parameters for required period were also obtained from Japan Meteorological Agency. Population data in Takamatsu area were also used to adjust ambulance transports and the number of death. The linkage among ambulance transports, the number of death and climate parameters was evaluated by ecological analysis. Results: Total ambulance transports (/a hundred thousand people/day) and ambulance transports due to acute disease (/a hundred thousand people/day) were 12.3 ± 0.9 and 6.8 ± 0.7, respectively. The number of death (/a hundred thousand people/day) was 2.5 ± 0.4. By quadratic curve, ambulance transports due to acute disease and the number of death were significantly correlated with the parameters of air temperature. However, the number of death was the highest in January and the lowest in August. Conclusion: Although higher air temperature was only associated with higher ambulance transports, lower air temperature was associated with both higher ambulance transports and the number death in Takamatsu area, Japan. © 2014 The Japanese Society for Hygiene.

We previously reported that a diet containing 65% paddy rice suppressed the colonization of Campylobacter jejuni in the cecum of broiler chicks, suggesting that this type of diet has positive effects on upper gastrointestinal tract function in broilers. To reveal the possible mechanisms involved in this antibacterial effect of the whole-grain paddy rice diet, we performed experiments comparing the digesta passage rate in the crop and gizzard, the development of gizzard, and the pH distribution in the gizzard between groups of chicks fed two different diets, such as ground corn and whole-grain paddy rice. During these experiments, we made the following observations: the chicks in the group fed the whole-grain paddy rice diet had more developed gizzards and significantly larger crop content than the chicks in the groupfed the ground corn diet. The chicks fed the whole-grain paddy rice diet retained the digesta in the crop for much longer and had less variation in the pH values in the gizzard than those fed ground corn. On the basis of these observations, we concluded that the hardness of the rice hull in whole-grain paddy rice leads to a larger amount and longer retention of content in the crop, as well as the uniformity of the internal pH of the gizzard, by promoting gizzard activity. We speculate that the hardness of the rice hulls promoted the grinding activity of the gizzard, resulting in the long retention time of the digesta in the cropand uniformity of the internal pH of the gizzard, which may sterilize or suppress Campylobacter growth in the gastrointestinal tract of broiler chicks. © 2016, Japan Poultry Science Association.

To examine the inhibitory effect of whole grain paddy rice diet (WPR) feeding on the colonization of Campylobacter jejuni in the cecum of broiler chicks, we performed the following examination. Sixty female broiler chicks (14 days of age) were allocated into two groups, thirty birds were fed a ground corn diet (GC) as a control group, and 30 chicks were fed WPR as an examination group. After feeding with the different diets for 16 days, six chicks were selected from each group(12 chicks in total), and each chick was inoculated with 2×103 colony-forming units of C. jejuni GTC03263. Forty-eight hours after the bacterial inoculation (the birds continued to be fed with the corresponding diets after the bacterial inoculation), the chicks (six from each group) were killed and dissected to detect bacterial colonization in the cecum. The other six chicks were dissected to weigh the chick gizzard and to measure the pH of its contents. No bacterial colonization was observed in the cecum of chicks in the WPR group, whereas bacteria were found in the cecum of five of six chicks in the GC group. The average ratios of gizzard weight to body weight of the WPR-fed chicks was significantly higher than that of the GC-fed chicks, whereas the average pH value of the gizzard contents was not different between the two groups. These results suggest that WPR feeding in broiler chicks has a positive effect on development of the gizzard muscle and grinding activity of the gizzard. Increased grinding activity may eliminate the regional differences in pH within the gizzard, resulting in less bacterial survival in the gizzard and then less bacterial colonization in the cecum of WPR-fed chicks than in GC-fed chicks. © 2015, Japan Poultry Science Association.
