    Fatty acids compositions of triglycerides (TG) and phospholipids (PL) in raised carp dorsal and ventral white muscles, and hepatopancreas were analyzed in summer and winter. TG level did not differ in the tissues between the seasons. PL level was higher in winter muscles, but did not differ in hepatopancreas between the seasons. Docosahexaenoic acid (DHA) was the major polyunsaturated fatty acid in TG and PL of the tissues. There were no seasonal differences in DHA, total saturated, monounsaturated and polyunsaturated fatty acids of TG and PL of the tissues analyzed. The results indicated that nutritional value of carp muscles as supplying source of DHA as well as polyunsaturated fatty acids does not differ between winter and summer.

    Heat disorder in Yamanashi Prefecture during July and August between 1995 and 1999 were investigated using both questionnaires, sent to members of Japanese Medical Association in Yamanashi (62 cases in five years), and also the data-base of patients transported by ambulance (152 cases in five years). As 9 cases were common to both data sets, the total cases reported were 205. The higher the mean maximal air temperature during August, the more incidences occurred. However, a constant tendency toward increase or decrease in the number of incidences over five years could not be recognized. Heat disorders may occur when the environmental temperature was higher than 28°C and the incidence significantly increased when the environmental temperature was above 35°C. The incidence was most significant at the beginning of a sudden increase of air temperature. There were two peaks in the incidence by age group, teenagers and those in seventies. The majority of the incidence (88%) occurred during outdoor exercise or work (or in a gymnasium). Especially in the younger group under sixties (first peak group), all cases, except those occurring in a car, occurred in this situation. However, in the older group above seventies (second peak group), heat disorder occurred during routine outdoor activities (e.g. walking, shopping) or even indoors, when the aged have chronic diseases or takes certain medicaments. The incidence was higher in males than in females (two thirds of cases were in male). Five patients died during 5 years. In 4 of these 5 cases, the core temperature was higher than 40°C and disturbances of central nervous system functions, including confusion or coma, were observed. As treatment, transfusion and, when core temperature was higher than 38°C, body cooling (body surface cooling, instillation of cold liquid, gastric lavage with cold liquid etc) were effective.

    The purpose of this study is to clarify the variations in residents’ posture while sitting in their living room from the standpoint of behavioral temperature regulation. Data was collected by questionnaire and interview. The frequency of the various postures for males in the living room was, in descending order, lateral decubitas, sedentary, sitting with legs stretched, and sitting with legs crossed in summer; and in winter, lateral decubitas, sedentary, sitting with legs crossed and sitting with legs stretched. The frequency of postures for females in the living room was, in descending order, sedentary, sitting with legs sideways, sitting with legs stretched, and lateral decubitas, in summer; and in winter, sedentary, sitting with legs sideways, sitting with legs stretched, and lateral decubitas. The thermal environment was found to affect the residents’ posture variation in the living room. Seventy-seven percent of the residents in winter and 58% in summer chose were to recline based on the level of thermal comfort. These facts can be interpreted as a type of behavioral temperature regulation.
