OBJECTIVE: Chronic Interstitial Nephritis in Agricultural Communities (CINAC) causes major morbidity and mortality for farmers in North-Central province (NCP) of Sri Lanka. To prevent the CINAC, reverse osmosis (RO) plants are established to purify the water and reduce the exposure to possible nephrotoxins through drinking water. We assessed RO plant maintenance and efficacy in NCP. METHODS: We have interviewed 10 RO plant operators on plant establishment, maintenance, usage and funding...

OBJECTIVE: The aim of this study was to investigate the therapeutic effects of a Sasa veitchii leaf extract (SE) on carbon tetrachloride (CCl4)-induced hepato- and nephrotoxicity. METHODS: Seven-week-old male ddy mice were orally administered SE or saline for seven days. Twenty-four hours after the last SE or saline administration, the mice were intraperitoneally injected with 3 g/kg CCl4 or olive oil. The mice from each group were euthanized and bled for plasma analysis 24 h after the CCl4/olive oil injection...

OBJECTIVES: Iodine intake by adults in farming districts in Northeastern Japan was evaluated by two methods: (1) government-approved food composition tables based calculation and (2) instrumental measurement. The correlation between these two values and a regression model for the calibration of calculated values was presented. METHODS: Iodine intake was calculated, using the values in the Japan Standard Tables of Food Composition (FCT), through the analysis of duplicate samples of complete 24-h food consumption for 90 adult subjects...

Because serum transaminases elevate alcohol dose dependently as a consequence of liver injury, they serve as useful biological markers of excessive drinking. However, these markers are inadequate in individuals with a defective allele of the aldehyde dehydrogenase 2 gene, ALDH2*2, because they show a different correlation with the amount of ethanol. For example, the serum alanine aminotransferase (ALT) level could become even lower than the baseline after alcohol intake in ALDH2*2 carriers. In fact, multiple studies suggest that ALDH2*2 is a hepato-protective factor in healthy individuals...

OBJECTIVE: The aim of this study was to investigate whether pretreatment with the Japanese herbal medicine "Hochu-ekki-to" (TJ-41) has an ameliorative effect on carbon tetrachloride (CCl4)-induced hepatotoxicity through anorexia prevention. METHODS: Twenty-four hours before CCl4 injection, TJ-41 or saline solution was intraperitoneally administered. Furthermore, 24 h after TJ-41 injection, mice were intraperitoneally administered 1.6 g/kg CCl4 or olive oil. Moreover, 24 h after CCl4/olive oil injection, mice from each group were euthanized and bled for plasma analysis...

OBJECTIVES: The aim of the present study was to examine the associations of current smoking with five other unhealthy lifestyle behaviors among urban civil servants in Japan according to sex and occupational category. METHODS: The study included 10,232 urban civil servants in Japan who presented for a health check-up in 2011. We analyzed data on anthropometric measurements and self-reported lifestyle factors. RESULTS: Current smokers had a higher BMI than never smokers in white-collar workers, but not in blue-collar workers of both sexes...

BACKGROUND: Health-related quality of life (HRQOL) has been reported to be associated with cognitive function; however, whether or not this relationship involves causality is uncertain. This study aimed to determine whether HRQOL levels are associated with subsequent changes in cognitive function in elderly people requiring care. METHODS: Participants were 74 community-dwelling elderly people utilizing the long-term care service (69 % women) who underwent physical and psychological examinations at baseline and follow-up...

OBJECTIVES: Studies have shown that inhaled mine dust, such as asbestos, can be translocated to various organs including the lymph nodes. Recently, we have established a protocol that enables us to identify inhaled elements using paraffin embedded lung specimens by in-air microparticle-induced X-ray emission (micro-PIXE). However, little research has examined the concentration of these inhaled fibers in various organs or the mechanisms of their translocation. In this study, we compared the concentration of inhaled fibers in the lung parenchyma to the concentration in the hilar lymph node as well as to determine the elemental spatial distribution of the inhaled fibers in a patient with occupational asbestos exposure...

Sensory impairments, mainly of vision and hearing, are prevalent among the older adults, and are the leading causes of disability in people aged 60 years and above around the world. However, epidemiological data on sensory impairments (prevalence, association with adverse health outcomes, risk and preventive factors, etc.) in community-dwelling older people are sparse in Japan. Using data from the Kurabuchi Study, a community-based prospective cohort study of adults aged 65 years or older, the author and colleagues estimated the prevalence of sensory impairments in this population...

The distribution of live births was investigated on those days and whether or not such dates were selected due to obstetric intervention is discussed. METHODS: Using a method similar to the [Formula: see text]-R control chart, anomalous variations in the hourly number of live births were detected...

OBJECTIVES: To prevent the onset of lifestyle-related diseases associated with metabolic syndrome (MetS) in Japan, research into the development of a useful screening method is strongly desired. We developed a new screening questionnaire (JAMRISC) utilizing a logistic regression model and evaluated its ability to predict the development of MetS, type 2 diabetes and other lifestyle-related diseases in Japanese populace. METHODS: JAMRISC questionnaire was sent to 1,850 individuals in Rumoi, a small city in Hokkaido...
