The effects of insulin administration on the normal growth of mouse skeletal muscle and its effect on induction of muscle hypertrophy by tenotomy were investigated in this experiment.
1) The influence of insulin dosage on rat body weight was investigated.
The results of examining the influence of insulin dosage on body weight showed significant increases in body weight in the 8.0U/Kg dosage group and 16.0 U/Kg dosage group compared to the control group.
2) The influence of insulin dosage on rat blood glucose levels was investigated.
The blood glucose values of the 1.0 U/kg dosage group were significantly lower than in the control group. They were significantly lower in the 1.0 U/kg dosage group than in the other dosage groups. The positive utilization of glucose in the peripheral organization was suggested.
3) The effect of insulin dosage on skeletal muscle weight was tested.
ANOVA shows a significant difference in soleus muscle weight as the insulin dosage rose. Soleus muscle weight at the 1.0 U/kg dosage was significantly higher than in the other groups. By contrast, no significant differences in muscle weight were observed in the control group as the dose insulin increased. The weight of fast muscle was unaffected by the size of the insulin dosage.
4) The influence of insulin dosage on the compensatory muscle hypertrophy was examined.
The influence of insulin dosage to the compensatory muscle hypertrophy was examined after one week. A 75% increase in soleus muscle after tenotomy was observed in the control group. Although the plantaris muscle showed an average 30% increase, the difference was not significant. A tendency for the weight of soleus muscle and plantaris muscle to increase after tenotomy was observed in the 2.0 U/kg dosage group, but the increments were not significantly different. Effect of tenotomy was observed weight of the soleus from an average of 7.3% in the 16.0 U/kg dosage group, but the increment was not significant. On the other hand, plantaris muscle weight increased about 65% and the increment was significant.

The purpose of this study was to investigate the relationship between low back pain (LBP) any physical characteristics in university wrestlers. We especially focused on radiological abnormalitie (RA) in their lumbar regions.
Physical characteristics and isokinetic trunk muscle strength of the 55 male university wrestlers were measured. MRI was used to evaluate the cross-sectional areas of trunk muscles between lumbar spine 3 and 4 (L3/4) . Evaluations of LBP were based on the diagnose of orthopedic surgeons and the questionnaire test. According to this evaluation, we assigned all wrestlers into two groups as the LOP group and the no LOP group. Furthermore, four groups were defined by having RA based on X-ray and MRI diagnose.
We obtained the following results. In comparison between the LOP group and the no LOP group, the trunk muscle extension flexion strength ratio of the LOP was significantly lower than that of the no LOP group. In addition, the LOP without RA group showed significant low strength of their trunk extensors in comparison with the no LOP without RA group.
We considered that the relative low strength of trunk extensors should have some effect on LBP in university wrestlers.

To evaluate training methods for basic clinical skills before bedside learning, we used questionnaires to ask students and instructors their opinions about the fixed-instructor system, in which one instructor teaches the entire course, and the rotation system, in which instructors share responsibilities for teaching according to their specialty. Students had positive impressions of training with both systems. Many students felt that communication with in structors was good inthe fixed-instructor system and that the specialized education provided by multiple instructors was good in the rotation system. However, students expressed dissatisfaction about differences in educational content between the systems. Instructors believed an advantage of the fixed-instructor system was that skills learned could be applied to all medical fields, whereas the rotation system made teaching easier because it was specialized. On the basis of this investigation, we conclude that training should establish good communication between instructors and students and should include the required educational contents. We also found that unifying educational contents is difficult, regardless of the training system. Few reports about educational methods used to teach basic clinical skills have been published in Japan, but studies focusing on this issue are becoming increasingly necessary.

BACKGROUND: In general practice, though patients often stop visiting ambulatory clinics of their own vo-lition despite the need for ongoing medical treatment, there is little reported research on the reasons for nonattendance in Japan. In this study, we investigated whether the patient/doctor relationship influences nonattendance rates in general practice. In addition, we investigated the reasons why patients stopped visiting the hospital.
METHODS: We collected data from 115 patients (58 males, 57 females; age range: 16 to 94 years old, median age: 52 years old) whose initial diagnoses were made in our department from June to July 2000. We classified the patients into five groups based on the level of their complaints concerning the initial consultation (‘A’ representing the highest degree of complaint, ‘E’ representing the lowest) and determined the relationship between the strength of complaints and the non-attendance rate. Furthermore, we investigated the reasons for non-attendance concerning 28 patients who stopped visiting the hospital from April 2000 to November 2001.
RESULTS: The non-attendance rates were 0% (014) for group A, 14.3% (2114) for group B, 5.6% (5189) for group C, 33.3% (216) for group D, and 50% (1/2) for group E. The rate tended to be higher in groups with fewer complaints. The reasons for non-attendance were the following: remission of symptoms (9 patients), request for another hospital or department (6 patients), relief due to consultation at the university hospital (6 patients), and lack of time to come to the particular hospital (5 patients) . In contrast, the most common reason for satisfaction at the time of consultation was ‘enough explanation and listening to complaints well’ in 7 of 11 patients who were satisfied with the consultation.
CONCLUSIONS: The level of patient's complaints at the time of consultation is related to the non-attendance rate. However, sufficient explanation about symptoms and careful listening to complaints are important for establishing a good patient/doctor relationship.

1) We investigated the patients'evaluations of the students, our management of the medical training, and the patients' recognition of our outpatient clinic education. We then requested the patients to give their opinions regarding such interviews.
2) The patients'evaluations of the outpatient clinic and the patients'recognition of our outpatient clinic education were relatively good, but some patients complained about the short duration of medical care and also expressed anxiety over the students'medical interview.
3) Many patients expressed the desire to positively participate in medical education because the patients had high expectations of the medical students.In addition, this interview training fulfilled the patients'desire to be listened to and have their concerns acknowledged.

Images of the concepts of “International Health” and “International Nursing” may differ among countries. In this study, we examined the images of these concepts among 49 Fijian students, 85 Taiwanese students, and 377 Japanese students by self-administered questionnaire between 2007 and 2008. Full usable responses were received from 45 (91.8%) Fijian students, 69 (80.0%) Taiwanese students, and 352 (93.4%) Japanese students.
The results were as follows.
Ninety six percent of Japanese nursing students, 89% of Japanese medical students, 77% of Japanese student from four other faculties, 58% of Fijian students, and 26% of Taiwanese students reported their image of “International Health” to entail “Hygiene in developing countries”.
Ninety-two percent of Japanese nursing students, 92% of Japanese medical students, 40% of Fijian students, and 35% of Taiwanese students reported their image of “International Nursing” to entail “Nursing cooperation in developing countries”.
The images of “International Health” and “International Nursing” among the Fijian and Taiwanese students were of“Public health and nursing for foreigners living in Fiji or Taiwan”, and “Public health and nursing skills, and advanced medical systems in Westerns countries”. Most students in the three countries had a strong interest in-International Health and Nursing”.
Increasing chance of taking international information and knowledge of Japanese college students may influence the result of this study. Education and rearing students who will work in the field of international health was considered very important.
