JOURNAL FREE ACCESSIn the development of hypertension and atherosclerosis, inappropriate diet, less exercise habit and psychological stress due to stressful social life are involved. In these disoders, abnormal life cycle induces abnormal biological rhythm. Spa treatment will be useful for the recovery from abnormal biological rhythm. Recently, preferential occurrence of cardiovascular disorders such as transient myocardial ischemia, myocardial infarction, sudden death and cerebral thrombosis has been reported between 6: 00 a.m. and noon. These facts suggest that the bathing in the morning should be avoided in such disease conditions. Although it is difficult to clarify the presence of abnormality of endogenous biological rhythm in cardiovascular disease, it is easily presumed that regular and cyclic stress decreases the risk of cardiac events. Spa treatment may be significant and natural treatment for the disorders in biological rhythm involved in cardiovascular disease.View full abstractDownload PDF (534K) -

JOURNAL FREE ACCESSRecent advance of technology in the field of laboratory medicine makes it possible to clarify the action of Balneotherapy upon the human body at the levels of organs, tissues, and cells. In our laboratory in Kusatsu, we have examined the effects of hot spring water bathing on the blood viscosity, platelet aggregation, fibrinolytic activity and lymphocyte subsets. On the basis of our experimental findings in addition to those reported by other investigators, the benefit and risk of hot spring water bathing from the viewpoint of medical science will be discussed.View full abstractDownload PDF (925K) -

JOURNAL FREE ACCESSBath preparations and bathing are closely related with our daily life, such as mode of bathing. Various kinds of bath preparations could come into the market, and consumers have a tendency to buy the goods in these lines at frequent intervals.
Bathing, above all head-out water immersion causes physiological, hemodynamic, and cardiodynamic changes. It has brought us the improvements of systemic circulation, and pulmonary circulation, due to absorption of chemical substances dissolved in bathing water, and hydro static pressure during water immersion. Indeed, Hot water immersion and spa treatments have been widely utilized as a device for performing rehabilitation in orthopedics, internal medicine and many so on. In an aspect of medical treatment using bath preparation (BATHCRIN®), it has been already known that it has potent hypotensive effect due to vasodilatation. This presents that purification of venous blood and improvement of peripheral blood circulation assisted vasodilatation with in regard to hemodynamics. Furthermore we show the outline of moisturing effect, sweeping effects, and softness of stratum corneum after water immersion with alkaline salts, oil, and saccharide respectively.View full abstractDownload PDF (961K) -

JOURNAL FREE ACCESSIt has been shown that cold acclimation enhances non-shivering thermogenesis (NST), while fasting decreases it in vivo. In the present study the effect of fasting (food deprivation for 48 hours) was investigated on the in vitro thermogenic activity of brown adipose tissue (BAT) of warm- (25°C) and cold-acclimated (5°C, 4 weeks) rats. Basal oxygen consumption of BAT and its responses to noradrenaline (NA) and glucagon were measured directly on the tissue blocks as an index of thermogenic capacity of BAT. Fasting decreased body weight in both warm controls (WC) and cold-acclimated rats (CA) . It also decreased BAT weight per unit body weight and BAT lipid content in CA, but not in WC. Basal oxygen consumption per whole tissue pad in CA was suppressed by fasting, but not in WC. The responses to NA and glucagon (increases from basal oxygen consumption per whole tissue pad) were suppressed by fasting in CA. In WC, fasting suppressed the response to glucagon but not to NA. These results suggest that the modification of glucagon- or NA-induced thermogenesis plays a significant role to reserve energy substrates in fasted state by means of decreased NST, especially in CA of which metabolism is enhanced and energy substrates are decreased.View full abstractDownload PDF (801K) -

JOURNAL FREE ACCESSThe thermopre-ferendum, the water temperature preferred behaviorally, by the Japanese freshwater snail, Semisulcospira libertina, was repeatedly measured in the course of a year, using an artificial habitat with a temperature gradient. The thermopreferendum displayed an annual cycle with an amplitude of 9.3°C and was in phase with the natural day length. The results have been integrated in the context of the phylogeny of biological rhythms observed with thermoregulation.View full abstractDownload PDF (668K) -

JOURNAL FREE ACCESSThis study was conducted to determine the interrelationship among body temperature, sweating and cutaneous blood flow during exercise. Six healthy males performed 40-min bicycle exercise of 40% VO2max at ambient temperature of 28°C (50% RH) . Rectal temperature (Tre), esophageal temperature (Tes), mean skin temperature (Tsk), forearm skin temperature (Tarm), forearm sweat rate (Msw), frequency of sweat expulsions (Fsw) and forearm skin blood flow (LDF) were measured. The following results were obtained: (1) Tre rose slower than Tes in the early stage of exercise. (2) The slope of plots of the relationship between Msw and Tre changed at the breaking point of about 37.8°C, while the slope of that between Msw and Tes showed no change. Consequently, it is suggested that the breaking point on Msw- Tre relationship is caused by the delay of response of Tre in the early stage of exercise. (3) Following the start of exercise, Msw and Fsw increased before Tes and Tsk rose, suggesting that central sudomotor activity is influenced by nonthermal factor (s) during the early stage of exercise. (4) The increase of thermal 'sweating appeared earlier than that of LDF. (5) Tarm and LDF showed different patterns of change; Tarm decreased while LDF remained constant during the initial phase of exercise. On the basis of these results, it is concluded that sweat rate and central sudomotor activity are closely related to internal temperature during exercise, but that some nonthermal factor may also be involved during the early stage of exercise.View full abstractDownload PDF (822K)
