The effects of erythrosine on motility of frog heart, rabbit duodenum and uterus isolated, and on mice intestinal motility and voluntary activity were investigated. The effect of erythrosine $2.3{\times}10^{-5}M$ on isolated frog heart showed a slight decrease of the amplitude of motility, and the heart motility stopped in $3.5{\times}10^{-4}M$. With the administration of erythrosine $3.4{\times}10^{-4}M$, the isolated rabbit duodenum showed a remarkable contraction and this effect was inhibited by atropine $1.4{\times}10^{-7}M$. The administration of erythrosine $2.3{\times}10^{-3}M$, produced a contractile effect on the isolated rabbit uterus, and the motility of $6.9{\times}10^{-3}M$ started to increase in contractions at first and finally stopped, keeping in continuous contractions. The effects of erythrosine 0.5, 1.0, 10, and 20mg/kg on mice intestinal motility were not significantly different from this of the normal control. With 20 and 40mg/kg of erythrosine, the effects on voluntary activity showed the decrease of 21 and 58% respectively, and voluntary activity of the mice pretreated with erythrosine 20 and 40mg/kg, induced by C. N. B. 30mg/kg showed the decrease of 57 and 78% respectively in contrast with the normal control group.

This research aimed to identify characteristics of housing repairs for the weak class in rural area. Data are analyzed by the status according to year focusing on voluntary activity of the Korean Institute of Rural Architecture that is performing more than 10 years. The results are followings. First, approximately 63.3% of residents living in benefit houses are 70s and 80s in their age. They are weak in financial and physical and they have more than two weak points. Second, housing repairs were performed total 1,990 cases among 797 houses and average 2.5 cases per one house. Repair work in house interior is at the highest, the next is repair work in kitchen, repair work related to restroom, repair work for housing structure improvement, and repair work for insulation in order. Third, repair work required difficult work process and high cost is tend to decrease recently. However, work changing of wallpaper and papered floor and performing in outside is tend to increase because it has simple work process and low cost. Finally, barrier free needs to be more actively reflected for the weak class in rural area.

There are have been reports that the distribution of electromyographical(EMG) activity is determined in a predictable manner by both the location and number of occlusal contacts. However, these reports placed an emphasis on whole dentition. Inclined plane contacts in the frontal plane are classified as A-, B- or C-types. Objectives: The aim of this study was to evaluate the relation between occlusal tooth contact patterns and EMG activity of masseter muscle during maximum voluntary clenching. Methods: Fifteen healthy human subjects(Mean age; 25.3 years) volunteered to participate in this study. Acrylic resin overlays were fabricated for upper 2nd premolars and 1st molars bilaterally, and offered 3 types(A-, B- and AB- type contact). EMG activity of the masseter muscles was recorded bilaterally during maximum voluntary clenching. Statistical analysis was performed using the one-way ANOVA. Results: The group with a A-type contact showed a statistically lower EMG activity of masseter muscle than that of natural group(p<0.05) and that of B- and AB- type groups(p<0.01) on both upper 2nd premolars and upper 1st molars. Conclusions: These results suggest that occlusal tooth contact patterns have an influence on EMG activity of masseter muscle during maximum voluntary clenching.

The study was attempted to observe effects of voluntary exercise on energy expenditure and on storage of excessive energy into body fat in adult mice. Mice, body weight 25-30g, were divided into two groups, exercise and sedentary group. Voluntary exercize by running wheel was allowed for former group but not for the mice of the latter group which were restricted by limiting space allowance 13.5$\times$11.5$\times$15.0cm per mouse. During a period of 4 weeks of feeding trial, they were fed ad libitum starch-casein based diet added with $^3\textrm{H}$-glucose (D-[1-$^3\textrm{H}$(N)]-glucose) at a level of 20 nCi per g of diet. Measurements were made to study hematology, lipase activity in epididymal adipose tissue, total contents of body waste and fat, and radiactivity of $^3\textrm{H}$-glucose incoporated into body fat. Dietary intake, body weight gain and amount of voluntary physical activities were also measured. The results obtained ard summarized as follows; 1) Amount of metabolizable energy intake, body weight gain and body fat were not statistically different between the two group. However, mice of the exercise group tended to show lower body weight gain body fat contants, but higher energy expenditure than those of the sedentary group. 2) Radioactivity of $^3\textrm{H}$-glucose incoporated into body fat appeared lower for exercise group expressd on a whole body fat basis. The activity was, however, higher for exercise group when expressed based on per g of fat compared to that of sedentary group. 3) Exercise group showed also higher activity of lipase in epididymal adipose tissue than the other group. 4) Mice whose physical activities were restricted appeared to have lower levels of hemoglobin and hematocrit values than of the exercise group. These results seem to support the theory that turn-over rate of body fat is activated by exercise and to suggest that consumed energy is to be converted primarily into body fat before its use as energy source by oxidation even during a period of continuous energy expenditure by exercise.

This study aimed to compare movement patterns of shoulder joints between the right and left symmetry in stroke patients and control subjects. This study proposes use of the voluntary response index (VRI) calculated from quantitative analysis of surface electromyographic (sEMG) and motion data recorded during voluntary movement as a feeding task. The VRI is comprised of two numeric values, one derived from the total muscle activity recorded for the voluntary motor task (magnitude), and the other from the sEMG distribution across the recorded muscles with the similarity index (SI). Five stroke patients and five age-matched healthy controls were recruited. Feeding motion was performed using the provided spoon five times with rests taken on a chair in between tasks. EMG data were digitized and analyzed on the basis of the root mean square (RMS) envelope of activity. The average amplitude of responses was calculated. Responsiveness and clinically meaningful levels of discrimination between stroke patients and control for EMG magnitude and SI were determined. The similarity index of the results from two successive examinations of both sides apart for stroke patients and control subjects were .86 and .95 in motion analysis and .84 and .99 in electromyographic analysis. The SI of sEMG data and motion data was significantly correlated in stroke patients. The data suggest that SI is a sensitive program for comparing and analyzing the symmetry of muscle activity and motion in both sides. This analysis method has a clinical value in grading muscular activity and movement impairment after brain injury.
