The relation between “Sho” in Kampo medicine (traditional Japanese medicine) and fingertip volume pulse wave (=pulse wave) was studied. The number of patients enrolled was 147. Patients were classified into 6 groups on the basis of their prescription and subjective and objective symptoms observed at the first visit: Kitai, Kikyo, Oketsu, Kekkyo, Suitai, Jinkyo. Anacrotic pulse time in Oketsu group was significantly longer than those in other groups (p<0.01). T-wave in Suitai group was significantly higher than those in other groups (left: p<0.01, right: p<0.05). Meanwhile, T-wave in Jinkyo group was significantly lower than those in other groups (p<0.01). In addition, factors which affect pulse wave were examined. There were significant relationships among anacrotic pulse time, blood viscosity, amount of T-cholesterol, HDL-cholesterol value. Moreover, T-wave showed a significant relationship to aging.

The aim of the present study was to examine the validation of prediction equation of basal metabolic rate (BMR) in Japanese female athletes. The study population consisted of 122 Japanese female athletes (age 20.2 ± 1.3 years, height 162.5 ± 6.3 cm, body weight (BW) 57.4 ± 7.7 kg, and fat-free mass (FFM) 45.5 ± 5.1 kg). Body composition was estimated by using air displacement plethysmography (BOD POD System). BMR was measured by indirect calorimetry using dougras bag tequnique, and predicted BMR was calculated from different equations based on FFM. When compared with measured BMR, predicted BMR from the equation of Taguchi et al. (BMR (kcal/day)= 26.9×FFM (kg)+ 36) and equation of Owen et al. were not significantly different. Whereas, predicted values from equation of Japan Institute of Sports Sciences, National Institute of Health and Nutrition and Cunningham were significantly different from measured value. Estimation error and Total error were smaller in equation of Taguchi et al. and Owen et al., however, equation of Owen et al. had a larger estimation error in the subjects who was small body size (less than 42kg) or large body size(more than 69kg). Furthermore, newer equation of Taguchi et al. (BMR=27.5×FFM+5) was developed from the pool data (n=205) in the present study. Standard error of estimation (SEE) of this equation was smaller than the equation of Taguchi et al., and systematic error was hardly observed.In conclusion, the newer equation of Taguchi et al. developed from measured BMR of Japanese female athletes was useful to predict BMR.

To survey risk factors in coronary heart disease, we compared serum fatty acid composition and lipids for university students in Japan (33 males and 29 females) and in the Netherlands (20 males and 19 females). No significant differences were found between the mean levels of cholesterol (Chol) and triglycerides (TG) between the subjects in the two countries. The mean levels of polyunsaturated fatty acid (PUFA), monounsaturated fatty acid (MUFA) and saturated fatty acid (SFA) of Japanese students were similar to those of the Dutch students. In both countries, the levels of Chol showed a positive correlation with the levels of PUFA, n−6 PUFA, linoleic acid (C18: 2n−6), and arachidonic acid (AA, C20: 4n−6) but no correlation with the percentages of PUFA and the ratio of PUFA/SFA. On the other hand, the TG levels correlated inversely with the percentage of PUFA and the ratios of PUFA/SFA in both countries. When compared to those of Japanese students, low eicosapentaenoic acid (EPA, C20: 5n−3) and high AA were found in the Dutch students (p < 0.001, respectively). The total amounts of n−3 PUFA in the Dutch were significantly lower than those in the Japanese (p < 0.001) but no differences among those of n−6 PUFA. The ratios of EPA/AA and n−3/n−6 PUFA of the Dutch students were lower than those of the Japanese students (p < 0.001, respectively). The ratio of EPA/AA showed a positive correlation with EPA but not with AA in both countries. The levels of Toc which will decrease the risk of coronary vascular disease (CVD) were lower in Japan than those in the Dutch in both sexes (p < 0.01, respectively). These results suggest that the low EPA and high AA levels and the low n−3/n−6 PUFA ratio may lead to greater incidence of CVD.

The effects of a 47-week diet of butter of safflower oil as fat in combination with casein or soy protein as protein were observed for the serum concentrations of lipids and fatty acid compositions in rat serum and heart. Serum total cholesterol (Chol) did not differ among the four experimental diet groups. In the butter groups, significantly higher low-density lipoprotein (LDL)-Chol and lower high-density lipoprotein (HDL)-Chol were observed than in the safflower oil groups (p<0.005, respectively). Higher levels of α-tocopherol were found in the butter groups than in the safflower oil groups (p<0.05) and in the casein groups than in the soy protein groups (p<0.01). In comparison with the safflower oil groups, the butter groups showed higher n-3 polyunsaturated fatty acids (PUFA) contents and lower n-6 PUFA contents in serum and the hearts (p<0.005).The ratios of n-3/n-6 PUFA in the butter groups in serum, 0.26 and 0.18, and in the hearts, 0.37 and 0.36, (butter-casein diet and butter-soy protein diet, respectively) were higher than those of the safflower oil groups of under 0.01 in serum and 0.02 and 0.03 in the hearts (safflower oil-casein diet and safflower oil-soy protein diet, respectively) (p<0.005). In the soy protein groups, higher n-3 PUFA contents in the hearts were found than those of the casein groups (p<0.05). This study suggested that the butter diet induces higher levels of n-3 PUFA and a higher n-3/n-6 PUFA ratio than the safflower oil diet in rat serum and hearts over a long feeding period.

While the session-RPE (rating of perceived exertion) method can quantify training volume in athletes, this method is not able to evaluate energy expenditure (EE) during a training session. We developed an RPE-based activity record for assessing EE during athletic training, and we compared its results to those obtained using the flex-heart rate (flex-HR) method. The EE of nine female collegiate endurance runners was assessed by the RPE-based activity record and flex-HR methods during eight days in the normal training season. Subjects were asked to record their RPE in the record at 5-minute intervals, and to wear a HR monitor during training. All subjects also participated in an incremental treadmill exercise test, which was used to determine their RPE-EE and HR-EE regression equations. Although the RPE-based activity record significantly overestimated EE (RPE-activity record, 572 kcal/session; flex-HR method, 499 kcal/session; p = 0.031), it had high validity relative to the flex-HR method (intra-class correlation coefficient, 0.891; 95% confidence interval, 0.845–0.923) and there were no systematic errors in EE estimation between the two methods. Therefore, the RPE-based activity record can be used to assess EE during training in female runners. However, RPE-based activity record might overestimate EE for athletes who have more intermittent activities during training than endurance runners, because RPE takes more time for returning to the resting level than HR when the intensity of activity declines. Further research is needed to verify the validity of the RPE-based activity record for assessing EE during other sporting activities or measurement conditions, and to identify the factors affecting the degree of estimation error associated with this method.

OBJECTIVEThe present study examined the levels of serum α-Tocopherol (Toc), retinol (Ret), cholesterol (Chol) and triglycerides (TG), and their correlations in the sera of people in Nepal.

METHODSThe survey was conducted on the general populace in the agricultural Terai region in southern Nepal. The study population consisted of 93 males and 83 females aged 10-68 years. Serum Toc and Ret were measured by high-performance liquid chromatography.

RESULTSNo significant differences were observed between the genders for the average of total Chol (T-Chol) (140 and 145 mg/100 ml, respectively), HDL-C (45 and 47 mg/100 ml), LDL-C (94 and 97 mg/100 ml), and TG (106 and 110 mg/100 ml), and the ratio of LDL/HDL (2.16). The levels of mean Toc (4.32 and 4.27 μg/ml) were about the same for both genders, while the mean Ret levels were significantly higher for males (624 ng/ml) than for females (535 ng/ml) (p<0.001). A direct relationship was found between the levels of Toc and Ret (r=0.46, p<0.001 and r=0.28, p<0.05 for males and females, respectively). Serum levels of Toc and Ret were positively related to the levels of Chol (r=0.48 and r=0.58, p<0.001 for males and r=0.49, p<0.01 and r-0.28, p<0.05 for females, respectively). The ratio of Toc/TG normalized to serum TG was directly correlated to the ratio of Ret/TG (r=0.79 for males, and r=0.72 for females, p<0.001, respectively) and the ratios of Toc/TG and Ret/TG were negatively related to the LDL/HDL levels (r=-0.49 and r=-0.43, for males, and r=-0.46 and r=-0.57 for females, p<0.001, respectively).

CONCLUSIONThe levels of Toc and Ret were low in the sera of people living in the southern rural Terai region in Nepal, and it was found that lower levels of Toc and Ret normalized to TG increased the ratio of LDL/HDL. These results suggest that greater intake of foods rich in Toc and Ret should be encouraged to reduce the erisk of coronary heart disease.
