JOURNAL FREE ACCESSProstaglandin E (PGE) and prostaglandins A plus B (PGA+B) were determined by radioimmunoassay in blood plasma obtained from eight men immediately after a progressive arm and leg cycling task to exhaustion. PGE increased by 47 percent from 45 ± 6pg/ml (mean ± SEM) at rest to 66±8pg/ml after exercise, but PGA+B were unaffected by the work. The cause of the exercise-induced elevation of plasma PGE is unknown, but may be associated with PGE release from working skeletal muscle.View full abstractDownload PDF (442K) -

JOURNAL FREE ACCESSThe effect of submaximal arm, leg, and“arm+leg”exercise on oxygen uptake (VO2), heart rate (HR), and pulmonary ventilation (VE) was studied in three male subjects. The“arm+leg”exercise was performed in ten different ways with different arm load ranging from 14 to 60% of the total work load. VO2 and VE were found higher in the arm exercise than in the other types of exercise at submaximal work. At a given work load, the lowest HR was observed in the“arm+leg”exrcise when the arm was loaded with 14 to 33% of the total work load. And the highest HR was obtained in the arm exercise. The higher HR during the arm exercise as compared to the legor“arm + leg”exercise may be accounted for by the fact that an exercise with small muscle group appears to elicit lower stroke volume and more pronounced rise in sympathetic tone. In the“arm + leg”exercise, HR at a given work load or VO2 varied with the proportion of arm load. However VE, whcih might be affected by stroke volume, was unaffected by the rate of arm to the total work load at a given work load or VO2. This indicates that the sympathetic tone may be affected by the proportion of work load distribution on the active msucle groups in the“arm + leg”exercise.View full abstractDownload PDF (2840K) -
CHANGES OF THE SKIN SURFACE LIPID FA OF WOMEN AT PRE- AND POST-LABOUR PERIODSKASUMI SAKAKI1980 Volume 29 Issue 1 Pages 11-20
Published: March 01, 1980
Released on J-STAGE: September 30, 2010
JOURNAL FREE ACCESSDetermination of work intensity of isometric exercises and mental works from the viewpoint of O2 consumption is not easily accepted, In an attempt to overcome such shortcomings, skin surface lipid metabolism has been examined. As an extention of the preceding effort, in the current study, the changes of the skin surface of the forehead of pregnant women has been analized by use of gas chromatography.
1) The secretion of the fatty acids was quite variable among the subjects, indicating the tendency of great individual differences.
2) Largest mean values among nine fatty acids examined were observed to be C16, C16-1, C18 and C18-1. On the other hand, most frequently appeared fatty acids were C14, C 16 and C18.
3) The composite ratios of fatty acids among those who recorded presence of these FAs, were 54% for C16, 27% for C18, 8% for C18-1, 5% for C16-1, and 5% for C14.
4) The amount of secreted FAs at the post-labour period was found to be about 10 times larger than those at the pre-labour period.
5) Subjects who recorded near 4 hours of pains hours (which is just about the average) showed less secretion of FAs than those whose pains hours were longer and shorter than 4 hours.
6) Subjects whose time of labour were in the afternoon recorded greater amount of FAs than those with their labour in the morning.
7) The changes in the amount of secreted FAs at the time of labour coincided with the general pattern of seasonal changes of FAs secretion.View full abstractDownload PDF (989K) -

JOURNAL FREE ACCESSIt is recently observed that there is in a tendency toward obesity or deficiency of endurance to the physique among schoolchildren. Consequently there is much interest for exercise through our nation.
Noting these facts, we conducted experiments similar to those previously reported for getting basic data of body composition, by loading 28-days exercise on male rats on 8 percent and 20 percent casein diets.
1. The food intake of the exercise groups was smaller than that of the control in each pair. During the exercise period, food intake of group II also showed similar decreases to those in group I, however, during the rest period, food intakes increased as compared to those of the control. In comparison of caloric requirement for 1g increase of body weight, exercised rats showed higher calories than the control in exercise periods. In the rest period, however, these caloric values decreased as compared with the control.
2. For organ weight per 100g of body weight, significant difference was observed in the heart and kidneys. The gastrocnemius muscles showed almost similar values to the control. The liver and testes did not differ in the weights per 100g of fat free mass of body between the exercise and the control groups.
3. The water contents (%) in the carcasses of exercised rats each fed the 8% and 20% casein diets in group I and I' differed significantly when compared with the control animals, but there was no difference in the water contents of the organs of all groups.
4. In the case of exercised rats in groups I and I', body lipid contents (%) were significantly lower than that of the control group, irrespective of the protein levels in the diets. On the other hand, for rats fed the 8% casein diet in group II, there was no difference in lipid content (%) in the carcasses as compared with the control rats. In the 8% and 20% casein diet groups, lipid contents (%) in the liver of exercised rats in groups I and I' also decreased considerably compared with the control level. In group II, the lipid content in the liver recovered to the control level or had a tendency to increase slightly.
5. The differences of body weight between the control and the exercised rats in each group were nearly equal to the difference of the sum of body lipids and water contents in the whole body between the two groups. From these data, it was suggested that the differences of body weight in each group between the exercised and control rats could be explained as the changes of lipids and water contentes in the body.View full abstractDownload PDF (1389K) -

JOURNAL FREE ACCESSStudents and general long distance runners carried out 1600m run for 24 hours and their physical functions were measured with lapse of the relay. Following results were obtained.
1) Prolongation of mean running time of student long distance runners in 1600m runs appeared at about 8th-10th runs, 12.8-16.0km, but that of general long distance runners did at 5th-6th runs, 8-9.6km.
2) There was plus correlation between mean of running time and its standard deviation in 1600m runs. It was r=0.55 and its regression equation was Y=0.58X-162.3. But these of general long distance runners were r=0.53 and Y=0.358X-97.3, respectively.
3) Decreased body weight from 1st-8th run was great and succesive, and occupied about 30%-70% of final decreased body weight. Thereafter, increase or decrease of the body weight was repeated and the time course became slow. There were some runners who showed large and succesive decreased body weight with the runs through the competition. The decreased body weight during the competition was influenced by the wind velocity, which supressed it considerably.
4) Heart rate of a student long distance runner during 1600m run reached 180-189 beats per minute every run. Resting heart rate of general and student long distance groups showed circadian rhythm during the competition, but that of student runners was higher through the competition and their systolic pressure shows a tendency to below in later period of the competition.
5) Threshold of knee jerk was low in the initial few runs and thereafter showed circadian rhythm. Reaction time to light was also facilitated in the initial runs and there-after prolonged about 30msec and maintained till the end of the competition. Frequency of subjective symptoms increased with number of the runs. At middle of the competition, it came over Sakai's standard and the A, B and C symptoms at the end of the competition were 33.0%, 20.0% and 25.0%, respectively.
6) Calorie intake per day of the student long distance runners was in the range of 1240-2540Cal. Total energy consumption was estimated 7457Cal. per day.
7) Blood glucose of the student long distance runners mostly unchanged through the competition, but serum triglyceride and total phospholipids significantly decreased and inversely serum free fatty acids prolongly mobilized.View full abstractDownload PDF (1423K) -

JOURNAL FREE ACCESSThe muscle fibers of M. rectus abdominis from 3 sportsmen (Weight-lifting, Boxing and Body-building) were examined histologically and compared with the mean of 22 human control subjects. Following results were obtained.
1. Compared with the M, rectus abdominis of control subjects, the sportsmen's rectus abdominis muscle area was about 4 times the cross-sectional area of muscle belly and the number of muscle fibers per sq, mm, were 1/3 that of the control specimens. The total number and mean size of sportsmen muscle fibers corresponded to the respective maxima of the controls, and the muscle fiber density in sportsmen corresponded to the minimum control value.
2. Comparing the myofibrous organization of 3 specimens, the muscle of the boxer was largest in cross-sectional area, in frequency of muscle fibers with large diameter, and in volume of interstitial connective tissue. It was the smallest of the 3 specimens in the number of muscle fibers per sq. mm. We found that the muscle of the weight-lifter was intermediate in these four categories.View full abstractDownload PDF (4626K) -
(STUDIES ON DONAGGIO REACTION PART II)SACHIO OHMORI1980 Volume 29 Issue 1 Pages 52-57
Published: March 01, 1980
Released on J-STAGE: September 30, 2010
JOURNAL FREE ACCESSThe purpose of this studies is to investigate the Donaggio reaction positive substances in serum, by the same method as urine.
'Obstacle phenomenon for precipitation of methylen blue and ammonium molybdate' had been also observed to be positive in serum.
Under the influence of stress (not only strenous physical exercise but also rest state, derived from the mainly catabolating of connective tissue), these substances had been guessed to pass into blood stream and thereafter into the urine.
Donaggio titer in serum solution only could not be measured by Sato's standard method, because of coagulation and impossibility of precipitation on deproteinization. It was found to be able to measure by mixing urine to serum.
Results obtained were as follows
1) Diluted serum, by mixing of utrafiltrated urine, kept high level of Donaggio titer.
2) Donaggio titer in serum decreased by deproteinization at pH. 5, especially by heat 100°C for 10 minutes.
3) Semi-quantitative isolation were performed by means of electrosyneresis, α1 acid glycoprotein (α1-AG), α1-anti trypsin (α1-AT), α1-anti xymotrypsin (α1-X) in α1 globulin region and Zn binding α2-glycoprotein (Zn-α2), α2 HS-glycoprotein (α2-HS) in α2 globulin region were identified as Donaggio positive substances from deproteinized serum.
Furthermore, identity of Donaggio positive substances between serum and urine must be examined by immunological technique, for example-line-immunoelectrophoresis.View full abstractDownload PDF (534K) -
