Background: and Purpose Neuropsychiatric symptoms (NPS) are frequent in dementia and mild cognitive impairment (MCI), yet their reported associations with white matter hyperintensities (WMHs) remain inconsistent. We examined item-level associations between WMHs and NPS across Alzheimer’s disease dementia (ADD), dementia with Lewy bodies (DLB), and amnestic MCI (aMCI). Methods: This multicenter retrospective study involved 523 patients: 276 with ADD, 67 with DLB, and 180 with aMCI. Three-dimensional T1-weighted and T2–fluid-attenuated inversion recovery magnetic resonance images were processed with BAAD (Brain Anatomical Analysis using Diffeomorphic Deformation) software to quantify WMH volume (WMHV) and gray matter volume (GMV), normalized to total intracranial volume (TIV). NPS were assessed using the Neuropsychiatric Inventory. Multiple regression analyses were performed within each group, adjusting for GMV/TIV, age, sex, years of education, Clinical Dementia Rating–Sum of Boxes score, and institution. Results: In the aMCI group, higher WMHV/TIV was positively associated with depression, apathy, and disinhibition, and negatively with delusions. Subregional analyses revealed NPSspecific topographic patterns. No significant associations were detected in the ADD or DLB group. GMV/TIV was positively associated with delusions in the ADD group, but negatively associated with hallucinations in the DLB group. Conclusions Associations between WMHs and NPS were evident in the aMCI group but absent in the ADD and DLB groups, suggesting a stage-dependent effect. WMHs may contribute to NPS primarily in prodromal stages, whereas their influence may be overshadowed by neurodegenerative pathology in dementia. Clarifying the mechanisms underlying WMHs is critical for evaluating their potential as intervention targets.

To determine the physical symptoms and ki, ketsu and sui (qi, blood and fluid) factors associated with the presence of hie-sho (chill syndrome). Total 118 healthy university students (66 males and 52 females, median age 22 years, range 21­-29) were enrolled. A cross-­sectional study about the presence of chill syndrome in par­ticipants was performed. Terasawa's ki, ketsu and sui diagnostic score was used to identify the presence of physical symptoms. Number rating scale (NRS) was used to classify the chill and NRS more than 5 was de­fined as chill syndrome based on Furuya's report. Eighteen students (4 males and 14 females) were docu­mented as chill syndrome. The multivariate analysis of physical symptoms identified female (OR 4.65, p = 0.0427), heavy sensation of head (OR 2.98, p = 0.0190) and chill of extremities (OR 1.94, p = 0.0480) as sig­nificantly associated factors with chill syndrome. The score of ki-kyo (qi deficiency), ketsu-kyo (blood defi­ciency) and suitai (fluid retention) showed higher score in students with chill syndrome compared to students without chill syndrome in univariate analysis. Being female and two indicators of qi abnormalities including heavy sensation of head and chill of extremities were associated with the presence of chill syndrome in univer­sity students.

Objective : To evaluate the effect of beraprost sodium (beraprost) on the vascular events occurring in patients with peripheral arterial disease (PAD) in a meta-analysis of placebo-controlled, randomized trials.
Design : Meta-analysis
Methods : Among the clinical trials of beraprost in patients with intermittent claudication associated with PAD, placebo-controlled, randomized trials with vascular events as outcome measures were selected. Two trials met the criteria, each of which was a comparative trial of beraprost (40 μg t.i.d.) and placebo (t.i.d.), with a six-month follow-up period.
Results : With both trials combined, the analysis included 594 patients in the beraprost group and 590 in the placebo group. The risk ratio was 0.608 (95%CI : 0.41 to 0.90, p =0.012), demonstrating the efficacy of beraprost on all vascular events. The risk ratio for lower limb deterioration was 0.598 (95% CI : 0.34 to 1.06, p =0.079), which was similar to that for all vascular events. A statistically insignificant but similar result was also obtained for cardio/cerebrovascular events with a risk ratio of 0.619 (95%CI : 0.36 to 1.07, p = 0.085). Heterogeneity between the two studies was not found for any of the events.
Conclusion : The results demonstrated the efficacy of beraprost on the vascular events in patients with PAD. The potential benefit of beraprost on vascular events will require evaluation in a larger prospective investigation.

Effects of sit-up exercise in the healthy adults to the point of exhaustion on the respiratory-circulatory functions and oxygen consumption were studied in thirtyone males and thirtysix females whose age varied between twenty and thirtyf our years old. The subjects were classified into two groups, the superior and the inferior, according to the number of sit-ups to reach the exhaustion point. Collected vallues were compared between the pre-exercise and the post-exercise records. The results were as follows ;
1) No sex differences in the inferior group were found in the degree of increase in systolic pressure, heart rate and respiratory rate.
2) In the superior group, no sex difference was found in the degree of increase in respiration rate, but male subjects were greater than female subjects in the degree of increase in both systolic pressure and heart rate.
3) In males, when the superior subjects were compared with the inferior subjects, the former were greater than the latter in the degree of increase in both systolic pressure and heart rate, but in females no differences were found.
4) In males the more the degree of increase in blood pressure, the more the degree of increase in heart rate. In contrast with males, in females there were no relation between them were observed.
5) It was recognized that relative metabolic rate varied in values from 4.7-13.5 and there was a tendency among the inferior subjects to have a large relative metabolic rate.

The present study was performed to investigate the effect of long distance walking upon physical functions for healthy male subjects. The first experiment was carried out in 1977, the second, in 1978, and the third, in 1979 in each autum season. At the first experiment, subjects began walking upon having breakfast, then ate and drank noting during first 30km, and took some foods during another 26km. Twelve hours and fifty minutes of time was spent for 56km walking including 15, 60, and 30 minutes rest periods in between. In the second experiment, subjects ate nothing after dinner of the previous evening and 35km walking took 6 hours during which some rest periods were taken for blood sampling. The third was 80km walking for two days. Subjects walked 40km in 8 hours in the first day and on the following day they walked 40km in ten hours and twenty minutes. They took foods and rest freely.
From the view points of the changes in blood and urinary recordings obtained from those three experiments, the influences of long distance walking on the body indicate as follows ;
1) In case of long distance walking while nothing to eat and drink, the rate of serum saturated fatty acids composition decreased and unsaturated fatty acids increased.
2) In a fasting state, blood glucose gradually decreased, LDH activity increased and blood lactate, GOT and GPT activity presented no significant changes on long distance walking.
3) It was shown that the longer distance to walk, the lesser tendency in blood triglyceride even though subjects take a carbohydrate rich diet while walking.
4) In fasting state, less than 35km walking without foods, the stress to the body seemed not to be critical.
5) More than 40km walking in a day, even though taking meals, would result a significantly severe stress for body.
6) As long as usual meals are taken, 80km walking for two days continuously, 40km in each day, would not result in such a physical stress over the following days.

Effects of 20km running uppn taking a low-carbohydrate, high-fat and protein diet on the changes in blood pressure, heart rate, body weight, skinf old thickness, blood components and urinary recordings in five healthy young men were investigated and the changes in these items which occured by taurine inducement were studied by double blind test method. The results were as follows:
1) As to the degree of decrease in body weight in 20km running, the case in taurine administration (T. A.) was more than in placebo administration (P. A.) .
2) As to the degree of increase in systolic pressure upon 20km running, T. A. was less than P. A. 3) The rate of creatine kinase isozyme (CK-MB) against creatine kinase (CK), which increased after 20km running in P. A., was possible to reduce by T. A.
4) T. A. was less than P.A. in the rate of increase in lactate dehydrogenase (LDH) on 20km running.
5) In P. A., triglyceride increased after 20km running, but in T. A., it decreased.
6) T. A, much influenced the rate of individual fatty acid composition on 20km running
7) T. A, was more than P. A. in the secretion of adrenaline on 20km running.
8) No changes were observed in other blood components and urinary kallikrein.
