A 50-year-old woman who had received hemodialysis for 8 years was admitted due to lumbago, fever and leukocytosis. Computed tomography and angiography revealed a supraceliac saccular aneurysm and right pleural effusion. Impending rupture of an infected supraceliac aneurysm was strongly suspected, and an emergency operation was performed. The aneurysm was almost completely resected and replaced by a 24mm Hemashield graft with reconstruction of visceral and intercostal arteries using partial bypass and deep hypothermia. Staphylococcus aureus infection was diagnosed based on the culture of the aneurysmal wall. The postoperative course was uneventful without any adverse neurological symptoms. After surgery, antibiotics were administered for 4 weeks intravenously. The patient is well 22 months after the operation.

Studies were made on the physical fitness and morphological development of 47 high ranking sumo wrestlers who are considered to possess gigantic physique and great strength.
Morphological measurements.
1) The average body height was 180.2cm which when compared to the average Japanese is remarkably tall, however, when considering the tendency for the first rate athletes in Judo, boating, baseball, and basket ball to become taller, recently, this is not particularly noteworthy (Fig.1) .
2) The average body weight was 122.3kg, and the average of the Rohrer's index was 210.5. This is remarkable and may be considered to be a characteristic of the sumo wrestlers (Table 1, Fig. 2) .
3) The development of the circumf erential measurements when compared to that of the long axis of the body was remarkable : waist girth, 114.9cm, and hip girth 115.7cm. The skinfold thickeness was 109.9mm which is remarkably thick. This nearly abnormal development of subcutaneous fat is a special characteristic of sumo wrestlers.
Physical fitness.
4) The average back strength was 181.2kg, and the average grip strength was 47.9 kg, which are unexpectedly small and inferior to those of the boating and heavy weight lifting Olympic athletes. The method of measurement of muscle strength may be somewhat problematic, however, the development of the muscles was surprisingly poor. (Table 4)
5) The sumo wrestlers were also remarkably poor in tests requiring body movement, such as, vertical jump (47.9 cm) and side step test (35.1 times) . These values are far inferior to those of athletes in other sports, and are even inferior to those of the average Japanese of comparable age. (Table 4)
6) However, in spite of their obesity, the sumo wrestlers were comparable to the athletes of other sports in body flexibility and response time. (Table 4)
7) Obese subjects are said to have weak respiratory function. The sumo wrestlers under observation had an average vital capacity of 4918.6m1 indicating a remarkably low value for their large physique.
8) The average points for the step test was 49.4 indicating a lower value than the average Japanese of comparable age.
9) A follow-up study of the measurements made during the past 4 years was made on a few Sekitori. Although no change was noted in body height, marked increases in body weight and circumferential measurements were observed. (Fig. 4)
10) When the higher ranking wrestlers were compared with the lower ranking wreatlers, it was found that, morphologically, the higher ranking wrestlers were superior in body weight and circumferential measurements, however, no significant difference was found in the functional aspect (Fig. 5, 6) . These facts suggest that morphological superiority is an important factor in winning a sumo match.
11) From the foregoing, it may be inferred that the special characteristic of the sumo wrestler is their well developed morphological features, especially girth, however, they are far inferior to athletes of other sports in their functional aspect. These points suggest that more consideration should be made on the sumo wrestlers' method of training and also on their mode of living.

OBJECTIVE: (1) To estimate the prevalence of atrial fibrillation (Af) in the general population of Saitama Prefecture, (2) to identify useful information obtained from subjects' history and laboratory findings for predicting imminent occurrence of Af.
DESIGN: Cross sectional study and retrospective cohort study.
SETTING: Annual health examination of the general population.
PARTICIPANTS: Subjects were 5, 375 men and 8, 419 women with a mean age±standard deviation of 47.2±9.6 and an age range of 18 to 88 years old.
MEASUREMENTS AND MAIN RESULTS: Among the 13, 794 participants who underwent conventional 12-lead electrocardiography (ECG) every year from 1994 to 1997, the prevalence of Af was 0.3%. The cross sectional data showed significant differences between male subjects with and without Af regarding age (P<0.0001), current treatment for hypertension (P<0.0001), arrhythmia (P<0.0001), angina pectoris (P<0.05), history of myocardial infarction (P<0.05), perception of palpitation (P<0.0001), perception of irregular pulse (P<0.0001), shortness of breath (P<0.0001), diastolic blood pressure (P<0.05), total cholesterol (P<0.0001), and casual glucose level (P<0.05) . Significant differences were also found between female subjects with and without Af with respect to creatinine (P<0.0001), current treatment of arrhythmia (P<0.0001), perception of palpitation (P<0.0001), perception of irregular pulse (P<0.0001), and HbAlc level (P<0.05) .
The retrospective cohort data identified 22 subjects who had persistent Af during the study period, and 20 (0.15%) who had newly developed Af during this period on the basis of consecutive ECG recordings of the 13, 772 participants in 1994-1996. Logistic regression analysis revealed that there were significant differences in perception of irregular pulse (P=0.0004), history of myocardial infarction (P=0.0134), fatigability (P=0.0243), aging (P=0.0039) and total cholesterol level (P=0.025) for men, and in history of arrhythmia (P=0.0007) for women between the group with and without Af.
The likelihood ratios and the respective 95% confidence intervals (C.I.) for ECG findings to identify the subjects who would develop Af were as follows: ST depression, 14.6 (C.I., 5.1-42) ; ventricular arrhythmia, 14.9 (3.9-56) ; incomplete RBBB, 9.2 (2.4-34) ; supraventricular arrhythmia, 8.9 (1.3-61) ; second-degree atrioventricular block, 342 (32-3624) ; abnormal Q wave, 16.3 (2.4-112) ; left atrial enlargement, 52.7 (7.2-383) .
CONCLUSIONS: Combining data from subjects' histories for the prediction of imminent Af among subjects in the general population is likely to be useful, especially for the elderly male population. Aging in men, in particular, is an important factor when combined with abnormal findings on conventional 12-lead ECG.

At medical fields, how should procurement processes of medical material be? We tried to research that onto Hospitals affiliated with the National Federation of Agricultural Cooperatives for health and welfare using questionnaire researchmethod to grasp the actual conditions of medical material procurement processes. The research was proceeded taking the hospitals which have more than a hundred beds as the object. The research requested 97 hospitals and fifty-three hospitals responded. From the research, we could get the following results. The enough results to judge as results; implementation of plan of buying budgets 79%, affirmance of clearance asset 89%, clarification of necessity 96%, trial calculation of profitability and productivity 98%, research for the use utility after adoption 76%, supplement of a job lot 91%, consideration of safety 96%, prime cost dropby joint purchase 61%. On the other hand, it is considered that following things are not enough results;document audit with suppliers' business outline and supplier record 34%, purchasing administrator's lack of acknowledgements of medical material 55%, dealing with immovable stock in subsequent occasion after changes of doctors 41%, efficient ability as in analysis of time by purchase products 59%, transaction expenditure of wastes 46%, reduction of labour by joint purchasing 59%. On the whole, it may be said that hospitals, which have purchase board , are trying to select products from various sides. However, it cannot be said that Secretariat's knowledge a bout medical product are not good enough to selectit. Therefore, deliberating with participants to the committee is important andclue. In this case, substance should be described visually and objectively as in a chart graph. It may bring us excellent purchasing on medical products by consideration of selecting standard.

The purpose of this study was to examine the effect of physical inactivity, produced by prolonged bed rest, on the excitability of the spinal motor neuron pool in humans, using the activity of soleus H-reflex.
Eight healthy male subjects underwent continuous bed rest with 6 degree head-down tilt for 20 days (BR group) . Ten different healthy male subjects maintained their usual daily life during the observation period for 20 days (control group) . Recruitment curves of H-reflex and M-wave were obtained from every subject. H slope/M slope (H slp/M sip) which shows the excitability of spinal motor neurons was calculated by using data in the recruitment curve.
The H sip/M sip in the BR group significantly increased after BR, compared to the pre-BR values (p<0.05) . In the control group, however, there were no significant differences in the H slp/M sip between the pre and the post-observation values. At the baseline, the H slp/M sip showed no significant differences between the BR group and the control group. After the BR, the H slp/M sip in the BR group significantly increased compared to the control group after the observation period (p<0.05) .
This study suggests that the excitability of the monosynaptic spinal motor neuron pool is facilitated by physical inactivity during BR.

A decrease in swallowing function growth may lead to drooling and a diminished quality of life in patients with tongue cancer. Common ways to counteract drooling include a reduction of fluid intake, and the administration of anticholinergics. These actions, however, may not often suppress drooling sufficiently. Here we report how the application of the formulation of scopolamine ointment near the mastoid process behind the ear resulted in the alleviation of drooling in a tongue cancer patient, after continuous intravenous scopolamine butylbromide infusion was unsuccessful. Dry mouth was noted as an adverse event, which was not problematic. Also, the ointment could be used without local dermatitis. Scopolamine ointment is much more convenient to use than continuous injection, suggesting the improved treatment for drooling in patients with tongue cancer.

We investigated the effects of the Chinese prescription “Shosaiko-To and Inchinko-To” on the liver function after releasing of obstructive jaundice on rats.
On control group, the values of GOT, GPT, T-Bil and ALP were recovered to the values before obstructive jaundice on 14th day after releasing of obstructive jaundice.
On the other hand, on the Shosaiko-To and Inchinko-To treated group, the values of GOT, T-Bil and ALP were significantly improved on 3rd or 5th day after releasing of obstructive jaundice (p<0.001, vs control).
The prescription of Shosaiko-To and Inchinko-To after releasing of obstructive jaundice indicated the prompt improvement for bile stagnation hepatitis.

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.
