Objectives: The purpose of this study was to clarify the effect of stone spa bathing (Ganban-yoku) and hot-spring bathing on brachial-ankle pulse wave velocity (baPWV) in healthy, late middle-aged females. Methods: The subjects were 13 females (mean age, 47.3 years). The skin and tympanic temperatures, blood pressure, and baPWV were measured before and after stone spa bathing and hot-spring bathing. For the stone spa bathing, the subjects lay down three times for approximately 10 min each time over warm stone beds. Results: Although body weight showed no change after the hot-spring bathing, it significantly increased after the stone spa bathing. The increase was significantly related to the amount of water intake. The skin and tympanic temperatures increased to a smaller degree after the stone spa bathing than after the hot-spring bathing. The diastolic blood pressure decreased to a smaller degree after the stone spa bathing. BaPWV showed no significant change after bathing both in the stone spa and in the hot-spring. The results of multiple regression analysis showed that the factors significantly related to the change in baPWV after the stone spa bathing were the changes in skin and tympanic temperatures and habit of smoking, and that after the hot-spring bathing was the change in skin temperature. Conclusions: The results suggest that, compared with the hot-spring bathing, stone spa bathing causes less strain on the body. The stone spa bathing and hot-spring bathing showed no marked effect on baPWV. However, there is a possibility that the stone spa bathing may be used as a load for investigating arterial stiffness.

It is important to promote microbiological research essential for long-term manned space activities under microgravity and in a completely closed environment in space craft in relation to long-duration space expeditions on the International Space Station (ISS) or to the moon and Mars in the future. Environmental monitoring data from the space shuttle, the Mir, and the ISS have already shown that microorganisms isolated from air and on inner surfaces of space craft were generally carried by crew members. The Japanese Experiment Module (JEM) “KIBO” was attached to the ISS and started its operation from 2008. It is an invaluable opportunity to begin the survey of the transition of microbiota, particularly fungal biota, in JEM from “brand-new” to “well-used” condition at various periods. Therefore, we are preparing the on-board analyzing systems for microbiota in air and on inner surfaces of ISS/JEM and normal microbiota of the astronauts themselves. In this paper, we introduce the current status and future plans on fungal research on ISS/JEM to protect flight crew members and flight hardware from potentially hazardous microorganisms from the environmental and biomedical aspects of Japan Aerospace Exploration Agency (JAXA).

The effects of aerobic capacity and body fat accumulation on the insulin response after an oral glucose load were investigated in 21 college students. The subjects were divided into three groups based on their insulin response after an oral glucose load: the first group showed a hyper and prolonged insulin response; HI (n=6), the second group showed a lower insulin response; LI (n=6), and the third group consisted of other subjects; MI (n=9). The maximal oxygen consumption in the HI group (29.6±3.3ml/kg/min) was significantly lower than that in the LI group (42.5±3.1ml/kg/min, P<0.05). Although no significant difference was observed in the body mass index between the HI (24.6±1.9) and LI groups (22.2±0.4, p>0.05), the body fat and the waist-to-hip ratio were significantly higher in the HI group (25.3±3.1%, 0.87±0.03) than in the LI group (12.9±0.7%, 0.76±0.01, P<0.05). All subjects in the LI group performed regular exercise, while none of the subjects in the HI group performed any regular exercise. These results suggest that an inactive life style, decreased aerobic capacity and increased body fat accumulation all appear to result in an increased insulin response after a glucose load.

Musculoskeletal disorders in workers decrease the productivity of companies and result in socioeconomic losses. Low back pain accounted for approximately 60% of occupational diseases in the past and this is still true at present, making it a major occupational health problem in Japan. Herein, the findings about low back pain are explained as follows: the correlation between imaging examination findings and low back pain is low; psychosocial factors are involved in the onset of low back pain and how it becomes chronic; and improvement of activity is more useful than rest. Furthermore, the advantages of employing physical therapists for improving occupational health are as follows: they can 1) evaluate and intervene ergonomically; 2) provide instructions using a behavioral modification technique based on psychosocial factors; and 3) provide instructions regarding exercise programs considering obstacles to the development of a good exercise habit (painful diseases including osteoarthritis and other diseases such as hypertension and diabetes). In addition, falling, whose incidence has recently been increasing and is an important issue in occupational health, is examined from the aspect of musculoskeletal disorders. The following activities of physical therapists are introduced: the items to be checked during a tour of inspection of a workplace and detailed descriptions of work management and working environment management measures. Physical therapists are rarely involved in studies of low back pain and falling, but their knowledge and skills have been demonstrated to contribute to improving occupational health.

The inner ears contain the organ of Corti, vestibule and semicircular canal. The organ of Corti is crucial for hearing, while the vestibule and semicircular canal play important roles in maintaining balance. Exposure to noise at excessive levels is known to cause damages of the inner ears, resulting in noise-induced hearing loss. On the other hand, noise levels (dB) are used for the evaluation of health risks by exposure to noise, although noise consists of sound with broad frequencies (Hz). Thus, information about the frequency-dependent effect of noise on health is largely unknown. In this review, we first introduce noise-induced hearing loss caused by exposure to audible noise. We then describe the imbalance in mice exposed to low-frequency noise (100 Hz).

Noise stress generated in industry is one of the environmental factors that physically affects the functions of the inner ear. Exposure to noise can cause hearing loss, resulting in serious problems in occupational and daily life. At present, however, there are very limited ways to prevent hearing impairments. The inner ear consists of the organ of Corti, vestibule and semicircular canal. Functional or morphological damage of these tissues in the inner ear caused by genetic factors, aging or environmental factors can result in hearing or balance impairments. In this review, we first introduce a deafness-related molecule found by our clinical research. Our experimental research using genetically engineered mice further demonstrated that impaired activity of the target molecule caused congenital and age-related hearing loss with neurodegeneration of spiral ganglion neurons in the inner ears. We also describe impaired balance in mice caused by exposure to low-frequency noise under experimental conditions with indoor environmental monitoring. We believe that our approaches to pursue both experimental research and fieldwork research complementarily are crucial for the development of a method for prevention of impairments of the inner ear.

In the previous papers, the author has clarified that excessive intake of S-methylcysteine sulfoxide (methiin) extracted from cabbage caused splenic hypertrophy and anemia. The present study was undertaken in order to clarify these effects of methiin on rats fed a low protein, high protein or commercial diet.<BR>(I) Male Wistar rats were separated into six groups and the following six different diet were given. Group A: a low protein (6% casein) diet, group B: low protein supplemented with 4% methiin, group C: normal protein (12% casein), group D: normal protein supplemented with 4% methiin, group E: high protein (18% casein), group F: high protein supplemented with 4% methiin. After 35 days, the rats werr sacrificed and various analyses were carried out. Red blood cell counts, hemoglobin and hematocrit in blood decreased and splenic weight and iron levels in spleen and liver increased in the methiin-supplemented groups B, D and F.<BR>(II) Male Wistar rats were separated into five groups and the following five different diets were given for 50 days. Group A: a synthetic diet (15% casein), group B: synthetic diet supplemented with 2% methiin, group C: commercial diet (Oriental Co., MF), group D: commercial deit supplemented with 1% methiin, group E: commercial diet supplemented with 2% methiin. The data revealed that symptoms of anemia and splenic hypertrophy were seen also in rats fed a methiin supplemented commercial diet as well as rats fed a methiin supplemented synthetic diet.

An epidemiological survey and clinical investigations were carried out on 162 retired workers from manganese mines and ore grinders, who were the residents of the Tamba district of Kyoto Prefecture. Most of the workers had been employed in small industrial factories with less than five employees under very poor working conditions. Fifty-five percent of them had worked in the mines and factories for longer than 11 years. Forty-six percent had been retired for 11-20 years, whereas 27% for longer than 21 years. A group of 124 people living in the same region but who had not been exposed to manganese served as the control group.The incidence of subjective symptoms associated with chronic manganese poisoning such as emotional instability, psychomotor irritability and neurologic abnormalities was apparently high in the experimental group and it increased with the period of exposure to manganese dust. Twenty-eight percent of the workers reported the subjective symptoms while they were employed, but 45% of them reported as late as six years after they retired.Of the retired workers, five (3.1%) had parkinsonism, three (1.9%) showed symptoms of hemiparkinsonism, and fifteen (9.3%) showed neurological symptoms including maskedlike, gait unbalance, slurred speech and imparied fine movements. Forty-five percent of these patients recognized these abnormalities for more than five years after they had left the contaminated workings. It is noteworthy that 39% of the retired workers were diagnosed as having pneumoconiosis.Some of the problems encountered in diagnosing manganese poisoning after exposure has been terminated is also discussed here.

We investigated the condition of the liver in a total of 5486 subjects (3889 males and 1597 females) who received adult-disease screening examinations.The following results were obtained.1. Fatty liver was found in 13.9% of the males and 3.8% of the females with a male/female ratio of about 3.7 to 1. In males, the prevalence of fatty liver was lower in those in their 20's than in any other age ranks, while there was little difference in the age range from the 30's to the 50's. In females, the prevalence sharply increased in those in their 50's.2. The percentage of fatty liver increased with the obesity index in both males and females.3. With respect to alcohol drinking, the prevalence of fatty liver was not affected by the presence or absence of alcohol drinking, the daily drinking quantity and total drinking quantity.4. Of those screened for adult disease, 14.7% of the males and 2.7% of the females had abnormal liver function, with a male/female ratio of about 5.4 to 1. In both males and females, the prevalence of fatty liver was higher in those who had abnormal rather than normal liver function.

Objective: The daily bisphenol A (BPA) intake level of Japanese pregnant women was surveyed based on the measurement of the urinary excretion level of a BPA metabolite.Methods: Spot urine samples were collected from 56 pregnant women who visited the gynecology division of a hospital for a routine health check between June and October 2003. The urinary concentrations of the BPA metabolite and creatinine were measured by GC/MS/MS and spectrophotometry, respectively. Daily BPA intake was assumed to be equal to daily excretion.Results: The daily intake of BPA among Japanese pregnant women was estimated to be in the range of <0.3 to 7.9μg/day (median<2.0μg/day), being consistent with the levels in previous studies for non-pregnant Japanese women. This level was far below the current Acceptable Daily Intake (0.01mg/kg/day) which was set by the European Commission. The maximum estimated intake per body weight (0.16μg/kg/day) reached 1/10 of the Lowest Adverse Effect Level of BPA for pregnant mice for a reproductive effect on the offspring (2μg/kg/day).Conclusion: It is desirable to lessen BPA intake from a precautionary viewpoint, particularly in pregnant women.

The studies were carried out to investigate the changes in the ammonia content of brain, liver, and blood under different physical environments. The environmental conditions studied were noise, cold, and immobilization.The adult male rats were exposed to 100∼105 phone noise characterized by wide octave band spectrum for 3 hours, or to cold (-10±1°C) for 3 hours, or were immobilized for 2 hours. There-after, the animals were killed by two different methods; the one was decapitated at room temperature and the other was dropped into the mixture of solid carbon dioxide and acetone. The brain and liver were rapidly removed, and homogenized in ice-cold 10% trichloroacetic acid with glass homogenizers. The blood samples were obtained by heart puncture. The determination of ammonia was made by Conway's method using Seligson-Hirahata's apparatus.As the results, under the noise condition, the ammonia content was elevated significantly in the brain, liver, and blood, but not under the other conditions.It may be concluded that the noise acts not as metabolic stimuli but as neurotropic stimuli with a peculiar nature.

It is well known that water colours and poster colours are made of inorganic pigments that then contain metals such as Cr, Pb, Fe, Co, Cd, Hg etc.. Recently, promoting the culture of sentiments, children practice painting with their fingers using water colours and poster colours, that is called the finger-painting. It is possible that inorganic metals contained in water colours and poster colours are potentially hazardous to children who practice painting in a private school. Each of four colours of red, blue, yellow and green of water colours and poster colours was analyzed for Cr, Pb, Fe, Co, Cd and Hg. And urinary Pb and Cd were determined on twenty five children, ages 4 to 11 of a private school of the painting and five control children ages 3 to 11. The following results were obtained.1) On the whole, water colours and poster colours contained a large quantity of Fe and Pb next to Fe. Especially yellow-2 of water colours contained a large quantity of Pb and showed 1, 012.5μg/g. The dissolved lead was found in water colours that were in lead tubes.2) The average of urinary Pb of tested children was 6.07±6.67μg/l(n=15), and that of control children 2.20±2.59μg/l(n=5). There were not significant difference at levels of 5% between the mean of subjects and that of the control.3) The average of urinary Cd of subjects was 0.68±0.94μg/l(n=25), and that of the control 0±0μg/l(n=5). There were not significant difference at levels of 5% between the mean of subjects and that of the control.4) The coefficient of correlation between experimental length in years and urinary Pb was 0.98, its regression line being yPb=3.18x+2.17(±2.92) as yPb for urinary Pb and x for experimental length in years.5) The coefficient of correlation between experimental length in years and urinary Cd showed 0.91, its regression line being yCd=0.23x+0.11(±0.25) as yCd for urinary Cd and x for experimental length in years.6) The coefficient of correlation between ages and urinary Pb was 0.10, and that between ages and urinary Cd was 0.72. Urinary Cd was apt to increase in proportion to ages.

We studied the role of S-adenosylmethionine (SAM) as a methyl group donor in the methylation of inorganic arsenic in mammalians.The SAM and S-adenosylhomocysteine (SAH) levels in the livers of untreated hamsters were 74.3±8.2 and 40.0±6.4nmol/g, respectively. The SAM level was 63.9±6.5nmol/g following oral administration of 1.5mg/kg of arsenic trioxide, which was 14% lower than the control level (t-test, p<0.05). This fall of the SAM level in the liver presumably derived from the SAM having acted as a methyl group donor.Oral administration of 1.5mg/kg of arsenic trioxide once only to hamsters pretreated intraperitoneally with 2.0mg/kg of SAM once only gave the following arsenic levels in the liver and urine. The dimethylated arsenic (DMA) levels in the livers of hamsters treated with SAM plus arsenic trioxide were significantly high, that is, 2 times as high as the control value at 6 hours, and 1.5 times as high as the control value at 24 hours after the administration of arsenic trioxide. The urinary DMA excretion rate in the hamsters treated with SAM plus arsenic trioxide during the first 24 hours after the administration was significantly higher, that is, higher by 36%, than the control value. The urinary DMA excretion rate following pretreatment with SAM was not dose-dependent. Pretreatment with methionine failed to exert any significant acceleratory effect on the methylation of arsenic trioxide.The decreasing pattern of the SAM level in the liver following administration of arsenic trioxide and the DMA behavior in the liver and urine following administration of SAM and arsenic trioxide revealed that SAM accelerated the methylation of inorganic arsenic. In other words, it appeared that SAM could be a very potent methyl group donor to inorganic arsenic.

Worldwide, lifestyle-related diseases such as type 2 diabetes and cardiovascular diseases are presently the leading causes of death and disability, and their incidences tend to increase. A lifestyle-related disease has been considered mainly to be induced by specific disease susceptibility genes and lifestyle after birth. However, the steep increase in the incidences of lifestyle-related diseases is difficult to be explained only by specific genes. Presently, a new theory has been proposed. Epidemiological and animal studies have disclosed the intimate links between malnutrition in the developmental stage and lifestyle-related chronic diseases. Such studies provide the foundation and framework for a new life science, that is, the theory of developmental origins of health and diseases (DOHaD). Although much research has been carried out to elucidate the putative concepts and mechanisms that relate specific exposures in early life to the risk of chronic diseases, a complete picture still remains obscure. Historically, the world has experienced severe famines, for example, the Dutch Winter Famine, the Chinese Great Leap Forward Famine, the Leningrad Siege and the Biafran Famine. These famines showed that malnutrition in utero poses higher risks of lifestyle-related diseases. The main research point has been focused on periconceptional and perinatal undernutrition and specific nutrient deficiencies. However, presently, the number of people who are overweight and obese has been increasing. Therefore, perinatal overnutrition and specific nutrient excesses should also be examined. In addition, psychological stress, environmental chemicals and artificial reproductive techniques are other important research fields in DOHaD.
