This study was to examine the relationship between bone maturation scores and the nutrition indexes, and to consider the estimated range for the evaluation of bone maturation scores. This study investigated the relationship between the bone maturation scores and the nutrition indexes of compound variables of height, body weight and sitting height, by the correlation coefficients in eleven items and used them as raw data for analysis.
The obtained results were as follows
1. The correlation coefficients between the nutrition indexes and bone maturation scores (Middle Phalanges) showed that in the second sexual period boys were significance at the level 0.05 in all the Rohrer, Kaup and Kawahata indexes. Each of them were as follows : Rohrer index 0.325, Kaup index 0.415, Kawahata index 0.485. In the girls also the correlation coefficients showed significance between the Rohrer, Kaup, and Kawahata indexes of all three phalanges scores, especially in correlation with the Middle Phalanges scores : Rohrer index 0.458, Kaup index 0.540, Kawahata index 0.424.
2. If the bone maturation scores are evaluated by the three nutrition indexes, it may be estimated that the bone maturation scores are evaluated by the Middle Phalanges scores for both boys and girls.
Regression Equations and the Standard Error (SE.) of estimate are as follows
Rohrer Index ; Boys : Y=12.42+0.75X, S.E.=±0.15
Girls : Y=10.00+1.55X, S.E.=±0.38
Kaup Index ; Boys : Y=10.48+0.62X, S.E.=±0.21
Girls : Y=8.23+1.13X, S.E.=±0.35
Kawahata Index ; Boys : Y=10.47+1.82X, S.E.=±0.21
Girls : Y=12.08+2.66X, S.E.=±0.29
note : X (nutrition indexes) Y (bone maturation scores)
3. The S.E, of estimated scores in bone maturation scores which were obtained by using each the nutrition index scores of the estimate equations were very small and the results of t-Test in the means of estimated scores and the means of actual measurement showed hardly any significant difference at the level 0.01. According to these results the estimate equations used here were considered to be of higher reliability.
4. The bone maturation scores were compared with the two groups, good and poor, classified by the nutrition indexes. In the case of the boys there was no significant difference in the Rohrer index.
But according to the Kaup and Kawahata indexes there were significant differences in each part of the bone except for the Proximal Phalanges scores. In the girls there were equally significant differences in all three nutrition indexes of the good-poor groups.
From the results found in this study, the nutrition indexes may by considered as an index to estimate the bone maturation scores, at least, of junior high school students in growing period.

The influence of aerobic and anaerobic components of muscular endurance on the lower limbs, on sprint ability while under conditions of muscular fatigue, was investigated. Fifteen track and field athletes (400 m sprinters, decathletes and middle distance runners) participated in the study in which running and sprinting movements at respective points (360 m and 50 m) along two distance conditions (400 m and 80 m, respectively), were filmed by high-speed video camera. Running speeds at each point were computed from the film analysis. The running speed at 360 m point was defined as the speed under fatigue, while the running speed at the 50m point was defined as the maximal speed. Further, the rate between speed under fatigue and maximal speed was defined as %Max. Speed. Maximal O₂ intake, O₂ debt and isokinetic muscular endurance were measured.
The results were summarized as follows :
1) Oxygen debt showed significant correlation with the average speed during 400m running (r=0.546 ; p<0.05), but not with the speed under fatigue (r=0.388 ; p>0.05) .
2) Speed under fatigue was positively correlated with muscular endurance of hip flexion and extension (r=0.683 ; p<0.01, r=0.572 ; p<0.05) .
3) Percent Max. Speed was negatively correlated with the maximal speed (r = -0.643 ; p <0.01) and positively correlated with the muscular endurance of hip flexion and extension, and knee flexion (r=0.640 ; p <0.05, r=0.517 ; p<0.05, r=0.646 ; p<0.01) .
These results suggest that; raising %Max. Speed to improve the muscular endurance of lower limbs and, to improve aerobic ability by developing the number of capillaries in the muscle, is important.

Kampo medicine is widely used in Japan for neuro-otologic disease (e.g. tinnitus, dizziness, hearing loss). Some patients with these diseases suffer from comorbidity of other non-otologic symptoms. We reviewed typical Kampo medicine formulations for neuro-otologic disease. Kampo extracts have indications not only the neuro-otologic but also other systemic diseases. Kampo medicine would facilitate the care of patients with both neuro-otologic diseases and comorbid symptoms.

Objective: To describe the case of a patient with intraperitoneal bleeding from the gastroepiploic artery by endoscopic ultrasound who was successfully treated with transcatheter arterial coil embolization.Patient and Methods: An 87-year-old man was referred to our hospital for examination of a gallbladder tumor. Endoscopic ultrasonography was performed using an oblique-view echoendoscope. After the endoscopic ultrasound, the patient went into shock. Computed tomography revealed a huge intraperitoneal hematoma and an aneurysm in the right gastroepiploic artery that were not seen on previous computed tomography images. Thus, urgent catheter angiography was performed, which showed a pseudoaneurysm of the right gastroepiploic artery and extravasation of the contrast medium from the pseudoaneurysm.Results: Transcatheter arterial coil embolization was subsequently performed, and the bleeding stopped. Thereafter, his hemodynamics stabilized and his general condition improved. The patient was discharged 22 days post-treatment with an uneventful course.Conclusion: Observation-only endoscopic ultrasound without invasive procedures can cause intraperitoneal bleeding due to a ruptured splanchnic artery. Thus, endoscopic ultrasonography should be performed more carefully in elderly patients.

Objective: Retrieval is challenging once prophylactic pancreatic stents migrate deep into the pancreatic duct. Herein, we describe a case of successful endoscopic retrieval of a migrated prophylactic pancreatic stent using a basket catheter through a biliary plastic stent pusher tube.Patient: A 71 year-old man was referred to our hospital for removal of a straight-shaped migrated 5-Fr 3-cm prophylactic pancreatic stent with a flap on the duodenal side. There were no subjective symptoms at the time of the hospital visit.Results: During endoscopic retrograde cholangiopancreatography, we inserted an 8.5-Fr plastic biliary stent pusher tube in front of the migrated pancreatic stent. The stent was then grasped using a basket catheter for peroral cholangioscopy through the biliary stent pusher tube. The stent was pulled into the pusher tube and was successfully retrieved from the pancreatic duct. No complications were associated with endoscopic retrograde cholangiopancreatography.Conclusion: Although rare, prophylactic pancreatic duct stent migration after pancreatic duct guidewire placement should be noted. In our case, endoscopic retrieval of a migrated prophylactic pancreatic stent using a basket catheter for peroral cholangioscopy through the biliary plastic stent pusher tube was successful.
