    Roentgenographic heart shadow and EKG of swimming athletes during rest and immediately after swimming were taken and the following results were obtained. A) Roentgenographic heart shadow. i) The enlargement of the heart shadow of sports athletes is fairly reversible and its mechanism is believed to be an adaptation to the working capacity. ii) The heart shadow of swimming athletes immediately after strenuous swim in most cases showed clear-cut contraction and this is believed to be chiefly due to large diastolic residual blood volume at rest. Thus the size of the heart shadow and the degree of contraction does not necessarily match and that an evident correlation with the working capacity was not seen is believed to be due to the inclusion of cases with irreversible change of enlargement. Moreover the working capacity is believed to be greatly influenced by periphera_??_ circulation including the lungs and by the autonomic nervous system and therefore the morphological change of the heart is rather the result of these factors. iii) The oxygen consumption of swimming athletes in step up test when compared with controls was high during exercise load but after completion of loading the opposity, i. e., reduction was seen. On the other hand, the changes of minute volume was about the same as controls. From these observations it is believed that the changes in the oxygen consumption seen in swimming athletes is caused chiefly by the increase of cardiac output. B) EKG i) During rest the ST segment of the left chest leads showed clear upward convex elevation in most of the cases and immediately after strenuous swim the tendency of this curve to become obscure was noted. This is believed to arise from the fact that a different ventricular gradient is seen from that found generaly. ii) Many cases showed a prolongation of the P-R interval during rest but these are some which showed a tendency to show an increase in prolongation immediately after strenuous swim. Therefore it is inadequate to explain a prolongation of P-R interval merely training-vagotony alone.iii) Cases showing incomplete right bundle branch block were relatively common and this finding was especially clear immediately after strenuous swim. This change can be interpreted as being the effect of ventricular dilatation due to extreme loading of the right ventricle but on the other hand, myocardial injury due to over strenuous training cannot be completely ignored.

    This paper is devoted to the report of an experimental observation of fatigue of mountain climbing. The observation was carried out at the hillside cottage on Mt. Tsubakuro, 2763 meter high when the auther engaged our duties as doctors there. Experiment 1. Observations were made in the time when they were going and returning from Mt. Tsubakuro to Mt. Daitenjo (about six hours on foot). The subjects were all healthy adults (ex. students or keepers of hillside cottage) who had acclimated themselves to mountain life. In this experiment Donaggio reaction of the urine, Flicker-test and threshold value of knee-jerk (P.S.R.) were observed consecutively in taking a method of study group of fatigue of Japan Industrial Hygiene Association. Regarding Donaggio reaction of the urine, Donaggio-value showed ascending tendency after the walk was over the maximum value was formed in the next morning and it was preserved in the same condition till the evening. The minimum fall in flicker-value was observed immediately after the walk. It gradually restored and was at the recover on the following. Regarding P.S.R, the maximum value was showed immediately after the walk and returned to normality after one hour rest. Experiment 2. 33 cases visited the mountain clinic were amounted to 33 including 22 males and 11 females. All of them have come from Tokyo or Kansai district by night trains. The most part of them reached the foot of the mountain early in the morning and got to Tsubakuro hillside cottage. They tried to walk through Mts. Yari and Hotaka after one night stay at the cottage. Those 33 cases were divided into 3 groups according to the following matters; Group A; normal (healthy adults in attendance on the invalids) Group B; slight illness (needed to have a rest). Group C; middle illness (needed an internal emergency treatment). The authors made the same observation on fatigue that was tried in the experiment 1. The results of the observation showed that to be worse in the order of group A, B and C. Fatigue is generally understood that its nature and extent was formed differently according to the method of observation used. The authors may consider that such observation made in this occasion can reveal, to some extent, the performance of methods of fatigue observation as well as the biological characteristics of fatigue itself. Because the present experiment was carried out onsuch continuous labour as mountain climbing uuder the condition of low atmaspheric pressure.

    1. The method of the anthrone reaction by Graff and his associates was used to determine serum polysaccharide levels in various diseases. The author modfied a part of this method and obtained results similar to other methods. 2. The parallel increase of protein-bound-polysaccharide and mucoprotein was observed in cases of malignant neoplasm, metastatic neoplasm of liver, collagen disease, uraemia and bacterial or non-bacterial infection. 3. Increase of protein-bound-polysaccharide and decrease of mucoprotein were observed in cases of hepatic diseases. 4. Though serum mucoprotein decreased in lipoid nephrosis, decrease of protein-bound-polysaccharide was not found. 5. Ratio of serum protein-bound-polysaccharide and mucoprotein was low in cases of acute inflammations and uraemia, and was high in cases of chronic inflammations, hepatic disease, lipoid nephrosis and diabates mellitus. 6. The parallel increase of serum mucoprotein and polysaccharide content of mucoprotein fraction were observed in various diseases, but its ratio became higher, more or less, in cases of hepatic diseases and diabates mellitus. 7. Clinically and experimentally, changes of serum glycoprotein levels in collagen diseases and in malignant neoplasm by many drugs, especially by adrenocorticosteroids and “anti-neoplasm-substances” were studied. Levels of serum glycoprotein became generally lower according to their rate of recovery from their conditions.

    By observing the rhythm of the impuls discharges with the E.M.G. during strychnine spasm in spinal frog, the effect of afferent stimuli was studied and the following results were obtained. 1) A series of afferent stimuli is evoked through the cutaneous nerve by placing acetic acid paper on the skin. In the short lasting stimulus the regular spasmic rhythm becomes irregular and some impulses appear in between spasmic impulses. The spasmic impulses are diminished and inhibited completely by the long lasting stimulus. 2) When continuous regular afferent stimuli are fed into spinal cord by electric stimuli applied to the cutaneous branch the inhibition of the spasm is strongly manifested. Even by a single stimulus the spasmc impulses are inhibited temporarily and the rhythm is reset by the stimulus without changing the regular period. 3) The spasmic rhythm is not disturbed by stimulating the muscle nerve. 4) When the afferent stimuli from the skin are reduced, the spasm is not ceased but the characteristic regularity of the spasm disappears. 5) The afferent route from skin is thought to be closely connected with the inhibitory interneurons which inhibit the motoneurons and play an important roll to make the spasmic rhythm.

    The present paper deals with a part of the series of author's studies on experimental arsine poisoning. The treatmental use of BAL, mercaptoacetic acid and cortone were studied on exporimental arsine poisoning to rabbits. Changes in their bodies were studied on blood formation and on the distribution of inhalated arsine in tissues by the method of Schümacher-pyronin staining. At these studies, the following results were obtained. 1. “BAL”, “Mercaptoacetic acid” and “Cortone” were ineffective in the treatment of acute arsine poisoning but effective for the chronic cases. 2. Using “cortone” for the chronic arsine poisoning, reduction of syptoms were found comparing to the control group.

    Selfexercise by individual patient is much more available for the treatment of the stiff joint, resulted from various kinds of the causatives, rather than an assisted exercise, such as a orthopedic massage. For this purpose, many apparatus have been used in these years, but most of them were complicated and expensive. Recently, being so popular the orthopedic surgery, more simple and more inexpensive apparatus is in great demand. Therefor, the authors deviced an apparatus for moving the stiff joint, which was adapted to each patient, as shown in figures 1-4. For adapting the apparatus in wide range of patient-status, some improvements were performed easily to make it longer or shorter. The main advantages of the apparatus are as follows : 1. The joint portion was made in double jointing. This strcture is suitable for either long_??_or short legs. 2. The thigh portion was made also in double strcture. 3. The ankle joint portion was made in an angle of about 150°C to eliminating the pain of the patient. Moreover, a soft material was placed on the ankle joint to prevent inflammation. 4. A handle was placed on the side of the apparatus for easier beding and stretching of the joint.

    A case of 17-year-old boy who had developed multiple enchondroma since his third year of age in the phalanges of the hands and feet, and many other bones of the extremities, ribs, scapulas, vertebrae and pelvis was reported. In this case a specific findings was obtained roentogenologically, and otherwise no abnormal symptoms were observed in the auto-nomic nervous, endocrine and cardiovascular systems. The blood examination revealed slight increases in lymphocytes count, hemoglobin content, acid phosphatase and calcium concentration, as well as a marked decrease in alakline phosphatase. This case was to be diagnosed as a VOLL, type of Kienböck. Roentgenogically the epiphyseal line was found to be completely closed, and the growth of the chondroma was thought to be at a standstill, displaying no tendency to relapse, hence the extirpation of the tumors was attempted for correction of the deformity. The process of the disease is still being followed.
