Dehydroepiandrosterone sulfate linked to physiologic response against hot spring immersion

The steroid dehydroepiandrosterone sulfate (DHEA-S) is associated with longevity and adaptation against external stress in humans. The aim of the study was to investigate the acute effect of a 30-min hot spring immersion at 41 °C on insulin resistance measures of 16 male subjects, in relation to DHEA-S level. To elucidate the role of DHEA-S in the coping against the heat stress, all subjects were evenly divided into lower and upper halves according to their baseline DHEA-S concentrations. The levels of glucose, insulin, blood pressure, and stress hormones (growth hormone, testosterone, and cortisol) in both groups were compared before and after hot spring immersion. The result shows that hot spring immersion significantly increased heart rate and reduced diastolic blood pressure, both of which were paralleled with a drop of DHEA-S concentration. Homeostasis model assessment for insulin resistance (HOMA-IR) and area under curve of glucose (GAUC) of oral glucose tolerance test were significantly increased by the hot spring immersion only in the Low DHEA-S group. Likewise, hot spring immersion caused an opposing effect on cortisol changes for the Low and High DHEA-S groups (+95% vs. −33%, p < 0.05), respectively. In conclusion, hot spring bathing induced insulin resistance confined only to those Low DHEA-S individuals. This response may be associated with a stress response such as increased cortisol levels.

複数の粘膜溢血斑を伴った吸血性ヒルによる鼻出血例

Only one bleeding point is typically seen in the local mucosa in most cases of nasal bleeding. We report here a rare epistaxis case suspected of multiple bleeding points on unilateral nasal cavity. A 64-year-old male had a one-week history of chance left-sided epistaxis. Multiple mucosal eruptions were seen on the inferior and middle turbinates and nasal septum of the left nasal mucosae. A dark brown mass was recognized near the frontal recess and removed. This mass was determined to be a live nasal leech. This patient had an history of leech exposure three months earlier while bathing in natural hot spring. Patients with a nasal foreign body usually have symptoms of foul-smelling purulent secretion and nasal stiffness with mucosal swelling. These symptoms are the result of rejection reactions by neutrophills against the foreign body. However, this reported case had no such symptom. This finding was supported that a live leech moves around the nasal cavity to escape human immune reactions.

掛け流し式温泉におけるレジオネラ属菌汚染とリスク因子

We examined water from 182 non-circulating hot spring bathing facilities in Japan for possible Legionella occurrence from June 2005 to December 2006, finding Legionella-positive cultures in 119 (29.5%) of 403 samples. Legionellae occurrence was most prevalent in bathtub water (39.4%), followed by storage tank water (23.8%), water from faucets at the bathtub edge (22.3%), and source-spring water (8.3%), indicating no statistically significant difference, in the number of legionellae, having an overall mean of 66 CFU/100mL. The maximum number of legionellae in water increased as water was sampled downstream:180 CFU/100 mL from source spring, 670 from storage tanks, 4,000 from inlet faucets, and 6,800 from bathtubs. The majority--85.7%--of isolated species were identified as L. pneumophila : L. pneumophila serogroup (SG) 1 in 22%, SG 5 in 21%, and SG 6 in 22% of positive samples. Multivariate logistic regression models used to determine the characteristics of facilities and sanitary management associated with Legionella contamination indicated that legionellae was prevalent in bathtub water under conditions where it was isolated from inlet faucet/pouring gate water (odds ratio [OR] = 6.98, 95% confidence interval [CI] = 2.14 to 22.8). Risk of occurrence was also high when the bathtub volume exceeded 5 m3 (OR = 2.74, 95% CI = 1.28 to 5.89). Legionellae occurrence was significantly reduced when the bathing water pH was lower than 6.0 (OR = 0.12, 95% CI = 0.02 to 0.63). Similarly, occurrence was rare in inlet faucet water or the upper part of the plumbing system for which pH was lower than 6.0 (OR = 0.06, 95% CI = 0.01 to 0.48), and when the water temperature was maintained at 55 degrees C or more (OR = 0.10, 95% CI = 0.01 to 0.77). We also examined the occurrence of amoeba, Mycobacterium spp., Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus in water samples.

Psychophysiological effects of bathing in hot spring evaluated by EEG

Background Lots of Japanese have a habit to take bath with hot water over 40 degree centigrade almost every day. More than 3,000 areas of hot springs exist all over Japan and according to the survey of Japan travel bureau foundation, 90% of Japanese like to visit there as a recreation. It has been reported that bathing in hot water can augment blood flow and those kind of physical effects while taking bath have already proved by certaion number of researcheres. However psychopsysiological effects in terms of bathing in hot water have not seen yet. Yoshida et al have developed the HSK rhytms(FFR) in alpha waves measured by EEG could show the mood states. In this study, we investigate comfortableness when people take hot bath using this EEG method.

Habitual hot‐spring bathing by a group of Japanese macaques (Macaca fuscata) in their natural habitat

Japanese macaques (Macaca fuscata) in a free-ranging group in Jigokudani valley, Nagano prefecture, are known to bathe in a hot spring. We used scan sampling in a study aimed at elucidating the causal factors and possible social transmission of this behavior. From 1980-2003, 31% of a total 114 females in the group habitually bathed in the hot spring. The habit was more widespread in dominant matrilines than in subordinate matrilines. Infants whose mothers bathed were more likely to bathe than infants of mothers who did not bathe. The number of monkeys bathing was clearly influenced by ambient air temperature. More monkeys bathed in the hot spring in winter than in summer. The results support the thermoregulation hypothesis of hot-spring bathing. Bathing behavior varies among age and sex categories of monkeys, with adult females and juveniles bathing more often than adult males and subadults. We compared hot-spring bathing with other thermoregulatory behaviors in various primate populations.

Legionella pneumophila Serogroup 1 Isolates from Cooling Towers in Japan Form a Distinct Genetic Cluster

Thirty-one epidemiologically unrelated Legionella pneumophila serogroup 1 isolates (10 from cooling towers, 10 from public spas and/or hot spring baths, and 11 from patients) were analyzed by pulsed-field gel electrophoresis (PFGE) and sequence-based typing (SBT) using 6 loci, flaA, pilE, asd, mip, mompS, and proA. The results of PFGE and SBT analysis indicated that all 10 isolates from cooling towers clustered into a unique type, which was distinct from strains of other environmental sources.

Comparison of Loop-Mediated Isothermal Amplification (LAMP) and Conventional Culture for the Detection of Legionella Species in Hot Spring Water Samples in Japan

We detected Legionella species in 125 samples of hot spring bath water from variousplaces in Japan using the culture and LAMP methods, and compared the results of the 2 methods. Legionella spp. was detected in 40 samples in the culture test, and 38 of these (95.0%) were also positive in the LAMP test, showing a high rate of consistency. Of the 85 negative samples in the culture test, 38 samples (44.7%) were positive in the LAMP test. The positive rate in the LAMP test was higher than that in the current culture test ; the test procedure wassimple, and judgments could be made in a few hours, showing that the LAMP method is useful for the rapid detection of Legionella spp.
