Intragastric pressure at gastric empty state was measured by radio capsule method during various exercises in three human subjects. The E. I. L. Type. 70. pressure sensitive radio capsule of England make was used in this experiment.
1) The empty intragastric pressure at rest was 30.0-33.0 cmH₂O and the gastric peristalsis was 2-3 sec. in frequency and less than 3 cmH₂O in amplitude.
2) The resting gastric peristalsis was disappeared immediately after the onset of deep respiration or exercise. The pressure raised to maximum 76.0 cmH₂O at the end of deep abdominal inspiration.
3) The intragastric temperature raised during various exercises and increasing grade was showed in Table of the text.

1) Tension development during rapidly grip strength exertion of athletes and nonathletes was by Natori's method analyzed.
2) Subjects of athletes were 71 healthy men of 17-26 ages and of non-athletes were 54 healthy men of 17-30 ages. Athletes were 26 high school students of 17-19 ages, 22 physical education college students of 19-21 ages and 23 general adult men of 20-26 ages. High school students were 3 Sumo-men, 4 Judo-men, 6 Kendo-men and 13 Baseball-men. Physical education college students were 6 Handball-men, 9 Rugby-men and 7 Gymnasticsmen. General adult men were 11 Judo-men and 12 Kendo-men. Non athletes were 20 high school students of 17-18 ages, 6 university students of 19-21 ages and 28 general adult men of 21-30 ages.
3) Isometric grip strength manometer were used a new device, to improvement on Smedley's manometer straingauge added.
Tension development were amplifired and recorded by portable Visigraph (Sanei-Sokki Ltd.) with paper-speed of 10cm/sec.
4) In the each case was 3 portions of a whole curve of time course of tension and Pmax.P₁, P₂; log t₁, log t₂; tan θ, tan ψ estimated according Natori's method.
5) Except general adults of 26-30 ages of non-athletes were Pmax. of athletes greater than non-athletes.
Pmax, of a Judo-man of general adult was greatest 68.5kg, and Pmax. of a high school student of 17 age of non-athlete smallest 35.8kg.
6) Tan θ and tan ψ of athletes were greater than non-athletes.
Tan θ of a Sumo-man of high school student was greatest 0.3628 and tan θ of a Judoman of general adult was greater 0.3500, but tan θ of a high school student of non-athletes was smallest 0.1624.
Tan ψ of a Kendo-man of general adult was greatest 1.6308 and tan ψ of a Sumoman of high school student was greater 1.5769, but tan ψ of a high school student of non-athlete was smallest 0.5278.
7) Muscle strength of non-athletes may well increased to be about 25 age, so that Pmax. of general adults of non-athletes were greater and of high school students of nonathletes smaller.
But athletes exercised usually for athletic sports, so that Pmax, and tan θ, tan ψ independent of age was greater than non-athletes, these were an each event varied. Pmax. of Judo-men of general adults were relative greater and tan θ, tan ψ were greatest. Pmax. of Handboll-men were greatest but tan θ, tan ψ were relative smaller. Pmax. of Gymnas-tics-men were relative greater but tan θ, tan ψ were smallest. So that were varied pattern of time course of tension development of hand grip exertion an each event of athletics.

Objective: Aerobic exercise on land decreases arterial stiffness, however, the effect of exercise in water on arterial stiffness has not been clear. This study investigated the effect of a 15-min cycling exercise on land and that in water on pulse wave velocity (PWV) as an index of arterial stiffness. Methods: Nine healthy young men were randomly performed exercise on land and exercise in water equivalent to 50% of each maximum oxygen uptake on separate days. The PWV from carotid to femoral artery (aortic PWV) and femoral to posterior tibial artery (leg PWV) were measured at baseline and 15, 30, 60 min after exercise. Results: The heart rate in water was significantly lower during exercise than that on land. In addition, the carbon dioxide output and respiratory exchange ratio during exercise were significantly greater in water. Body temperature increased after the exercise on land but decreased after the exercise in water. Although the aortic PWV and leg PWV decreased concomitantly with decrease in SBP and DBP after the exercise on land, there were no significant changes after the exercise in water. Conclusion: Although acute exercise on land decreased arterial stiffness after exercise, acute exercise in water of the same exercise load did not. The differences in body temperature and blood pressure after exercise may result in diverse arterial stiffness after exercise.

　　A 56-year-old woman was referred to our hospital because of an abnormal finding in the right pulmonary hilum on chest X-ray. Enhanced chest computed tomography showed hyperplastic bronchial arteries dilating and winding around the trachea and bronchi. A racemose hemangioma of the bronchial artery with multiple bronchial artery aneurysms (diameter <20mm) was seen displacing the trachea and both main bronchi. Bronchoscopy showed submucosal tumor-like lesions at the distal trachea and in both main bronchi, and a dusky-red elevated pulsatile lesion at the orifice of the left B3b＋c. We performed coil embolization of the bronchial artery aneurysm to prevent abrupt rupture of the bronchial aneurysm.

Students' interviewing skills are now commonly evaluated with standardized patient-based assessment methods. Four pairs of instructors at Nihon University School of Medicine used objective structured clinical examinations to evaluate the medical interviewing skills of 122 fifth-year medical students. The results were then analyzed to improve the accuracy of rating with objective structured clinical examinations. Interrater variability was significant among the two pairs of instructors. Variability was greatest when instructors evaluated a student's performance but was minimal when they judged whether a student had carried out a task. The number of standardized patients was 8, with the average score of each standardized patient ranging from 52.5 to 73.3 (full score, 100). These results suggest that the rating process for each item should be further refined and that the standard for evaluation should be clarified.

STUDY DESIGN: Retrospective study. PURPOSE: We conducted a study to investigate the time course changes in bone metabolic markers after the administration of the anti-receptor activator of nuclear factor-kappa B ligand (RANKL) antibody and to assess drug compliance among osteoporotic patients. OVERVIEW OF LITERATURE: The anti-RANKL antibody is expected to provide an improvement in those with a bone metabolism disorder. However there are only a few clinical reports available on the effect of treatment. METHODS: We included 40 post-menopausal osteoporotic patients who received the anti-RANKL antibody. To determine the time course changes in the bone metabolic markers, we measured the serum tartrate-resistant acid phosphatase 5b (TRACP 5b; a bone resorption marker) and the serum N-terminal propeptide of type 1 collagen (P1NP; a bone formation marker) levels prior to and 1 month after administrating the anti-RANKL antibody. To evaluable drug compliance, we assessed the dropout rate during treatment and at 6 months after treatment. RESULTS: The average TRACP 5b level significantly decreased from 574.8 mU/dL before treatment to 153.2 mU/dL 1 month after treatment (p<0.05). There was no significant difference in the average P1NP level, which was 56.9 microG/L and 35.1 microG/L before and 1 month after treatment, respectively (p>0.05). As for drug compliance, we did not have any dropouts during the treatment or after 6 months (dropout rate: 0%). CONCLUSIONS: Our study suggests that anti-RANKL antibody treatment suppresses bone resorption and maintains bone formation.

BACKGROUND/AIMS: The association between clinical symptoms, gastric emptying, quality of life and sleep disorders in distinct functional dyspepsia (FD) patients has not been studied yet in detail. METHODS: We enrolled 79 FD patients (postprandial distress syndrome [PDS], n = 65; epigastric pain syndrome [EPS], n = 47; EPS-PDS overlap, n = 33) and 44 healthy volunteers. Gastric motility was evaluated. We used Rome III criteria to evaluate clinical symptoms and State-Trait Anxiety Inventory (STAI) scores to determine anxiety status. Sleep disorder was evaluated using the Pittsburgh Sleep Quality Index scores. RESULTS: There were no significant differences in age, sex and Helicobacter pylori positivity between FD subtypes and healthy volunteers. The scores of Glasgow dyspepsia severity scores (GDSS), SF-8 and Pittsburgh Sleep Quality Index (PSQI) in distinct subtypes of FD patients were significantly different from those in healthy volunteers. However, there were not significant differences in these scores, Tmax and T1/2 among 3 subtypes of FD patients. PSQI score was significantly (P = 0.027, P = 0.002 and P = 0.039, respectively) associated with GDSS among EPS, PDS and EPS-PDS overlap patients. In addition, 8-item short form health survey (SF-8; Physical Component Score and Mental Component Score) was significantly associated with global PSQI score in PDS and EPS-PDS overlap patients. In contrast, SF-8 (Mental Component Score) only was significantly linked to global PSQI score in EPS patients. CONCLUSIONS: Prevalences for sleep disorders, gastric motility and quality of life in 3 subtypes of FD patients were similar levels. In PDS and EPS-PDS overlap patients, SF-8 was significantly associated with global PSQI score.

There were some mistakes in the numerical values of the graphs.

BACKGROUND/AIMS: There are no available data about the relationship between ghrelin gene genotypes and early phase of gastric emptying in functional dyspepsia (FD) as defined by Rome III classification. METHODS: We enrolled 74 patients presenting with typical symptoms of FD and 64 healthy volunteers. Gastric motility was evaluated using the 13C-acetate breath test. We used Rome III criteria to evaluate upper abdominal symptoms and self-rating questionnaires for depression (SRQ-D) scores to determine status of depression. The Arg51Gln (346G>A), preproghrelin (3056T>C), Leu72Met (408C>A), Gln90Leu (3412T>A) and G-protein beta3 (825C>T) polymorphisms were analyzed in the DNA from blood samples of enrolled subjects. Genotyping was performed by polymerase chain reaction. RESULTS: There was a significant relationship between the Gln90Leu3412 genotype and SRQ-D score in FD patients (P = 0.009). Area under the curve at 15 minutes (AUC15) value was significantly associated with the Leu72Met408 genotype (P = 0.015) but not with entire gastric emptying. CONCLUSIONS: The Leu72Met (408C>A) single nucleotide polymorphism was significantly associated with early phase of gastric emptying in FD patients. Further studies will be necessary to clarify the association between ghrelin gene single nucleotide polymorphisms and early phase of gastric emptying in FD patients.

Methods: Cases of 50 patients with ASD who underwent long spinal fusion (>9 levels) with S2AI screws were retrospectively reviewed. Loosening of S2AI screws and S1 pedicle screws and bone fusion at the level of L5–S1 at 2 years after surgery were investigated using computed tomography. In addition, risk factors for loosening of S2AI screws were determined in patients with ASD. Results: At 2 years after surgery, 33 cases (66%) of S2AI screw loosening and six cases (12%) of S1 pedicle screw loosening were observed. In 40 of 47 cases (85%), bone fusion at L5–S1 was found. Pseudarthrosis at L5–S1 was not significantly associated with S2AI screw loosening (19.3% vs. 6.3%, p=0.23), but significantly higher in patients with S1 screw loosening (83.3% vs. 4.9%, p<0.001). On multivariate logistic regression analyses, high upper instrumented vertebra (UIV) level (T5 or above) (odds ratio [OR], 4.4; 95% confidence interval [CI], 1.0–18.6; p=0.045) and obesity (OR, 11.4; 95% CI, 1.2–107.2; p=0.033) were independent risk factors for S2AI screw loosening. Conclusions High UIV level (T5 or above) and obesity were independent risk factors for S2AI screw loosening in patients with lumbosacral fixation in surgery for ASD. The incidence of lumbosacral fusion is associated with S1 screw loosening, but not S2AI screw loosening.
