In the previous paper, the authors have investigated a Chinese crude drug Ge-gen, the root of Pueraria species of the family Leguminosae, and concluded that it should be collected in the early summer for medical use. This is a report of the differences in the content of the constituents between Ge-gen harvested in the summer and in the winter. Yields of water extract of winter Ge-gens were generally higher, while no significant difference was recognized in the content of starch and flavonoids, such as puerarin and daidzin. Starch content varies widely with the stock, and that of the same stock did not show significant difference between the summer root and the winter one.

Objective: Routine, population-based mammographic screening for breast cancer has been implemented nationally in Japan for the past decade. The objective of this study was to evaluate the knowledge of the general public and of nurses concerning breast screening practices in Japan, especially with regards to the benefits and risks of breast cancer screening.
Methods: In 2014, a questionnaire regarding the benefits and risks of breast cancer screening was administered to women who underwent breast cancer screening and to registered nurses. The questionnaire was distributed to 1,649 women and 1,905 registered nurses.
Results: Completed questionnaires were returned by 1,552 (94.1%) of the screened participants and 1,710 (89.8%) nurses. The majority of the screened participants and registered nurses believed that screening prevented or reduced the risk of developing breast cancer (86% and 62%, respectively); that screening reduced the mortality risk of breast cancer by more than 50% (69% and 60%, respectively); and that 10 years of regular screening for 50-year-old women could prevent ≥ 10 breast cancer deaths per 1,000 women (62% and 61%, respectively).
Conclusions: Women in the target population and registered nurses were aware that earlier diagnosis led to better prognosis, but demonstrated misconceptions regarding other aspects of the benefits and risks of breast cancer screening. In Japan, all women should be educated on both the benefits and risks of breast cancer screening to enable them to make an informed decision on whether to participate in the mammographic breast cancer screening program.

The purpose of this study was to examine effects of moderate-intensity endurance exercise on reactive oxygen species production and leukocyte activation markers in young and middle-aged persons. Blood samples were collected before and after the jogging of 10 km. Although cytokines recruiting and priming neutrophils and monocytes were released into the circulation and functional after the jogging of 10 km, reactive oxygen metabolites-derived compounds (d-ROMs) were not significantly increased. It was indicated that chemokines and leukocyte activation markers at rest were increased with aging, and that might be accompanied by the higher level of d-ROMs in the elderly.

Adipose triglyceride lipase (ATGL) catalyzes the first step of triglyceride hydrolysis. The gene mutations cause neutral lipid storage disease with myopathy (NLSDM) and/or triglyceride deposit cardiomyovasculopathy (TGCV) . Here we give the first report on rehabilitation of a patient with NLSDM and TGCV. The 62-years-old patient was admitted to our hospital for rehabilitation for skeletal myopathy and rehabilitation for cardiac dysfunction (NYHA class Ⅲ , ejection fraction 20%) . He complaint of dyspnea during the activity of daily life and exercise torelance was low. Our rehabilitation program consisted of physical therapy, occupational therapy, nutrition and cardiac education. We had paid a special attention to the intensity of exercise (aerobic training and resistance training) due to the low cardiac function, energy dysfunction and myopathy. After rehabilitation for two months, muscle strength had increased and 6MWT, ATVO2 had improved. Importantly, the reduction of dyspnea on exertion as well as the increase in exercise capacity are considered to have led to improvement of quality of life.

The Medical Education Development Center has organized seminars and workshops for medical education 30 times from 2000 through 2008 throughout Japan. The participants have numbered more than 3200 and have included educators, physicians, students, and simulated patients. The topics of seminars and workshops have included problem-based learning tutorial systems, medical interview skills, objective structured clinical examinations, evidence-based medicine, coaching technology, simulations, and community medicine in response to educational needs. A questionnaire survey of 1793 participants of the 11th to 30th seminars and workshops (response rate, 85.6%) showed a high degree of satisfaction (4.33±0.13 of 5 points). Invited lecturers and directors from throughout the country often organized these workshops. The results of workshops are reported in our annual monograph, "Trends in Medical Education."

To assess the effectiveness of a problem-based learning tutorial system introduced at Gifu University School of Medicine in 1995, we conducted a questionnaire survey of medical knowledge, attitudes about learning, communication ability, and social behavior in sixth-year medical students. The questionnaire was given to instructors and attending physicians at community hospitals who were involved in clinical education. Many of the evaluators felt that students who trained with the tutorial system showed improved understanding, a more active attitude toward learning, and a better attitude toward patients than did students who received traditional, lecture-based education.

The Common Achievement Tests Organization performed the first nationwide trial of computer-based testing (CBT) used to assess students entering the clinical phase of medical education. Seventy-seven medical schools participated in the trial. We compared performance on the national CBT with performance on preclinical tests administered at Gifu University School of Medicine. Despite some methodologic differences between the national CBT and our system, the overall results correlated well. Students who did poorly on the national CBT also did poorly on Gifu University's preclinical test. Correlation of these two performance scales suggests that nationwide CBT could be used to accurately assess preclinical skills.

This article surveys current technical advancement in neuroendovascular therapy. The technical advancement happens not only in the field of products of microcatheter and guide wire but in the field of diagnosis. In the local intraarterial fibrinolysis, diffusion weighted MR imaging allows us more precise patient selection. In the atherosclerotic lesions, stent is clinically available. Some types of stent can be used in intracranial arteries. In the acutely ruptured aneurysm, intraanerysmal embolization using Guglielmi detachable coil followed by intratechal tissue-type plasminogen activator reduced occurring rate of vasospasm. In the wide neck aneurysm, neck plasty technique brings us better results. Neuroendovascular therapy is still evolving supported by such technical advancement.

Background: Development in internet technology
enables e-learning at the higher education level. We have
developed the Internet PBL-Tutorial System/Rakuichi
that allows multi-directional communication among
participants with web-based bulletin boards. Although
this system has been successful in medical education at
the undergraduate level, we sought to encourage “readonly
members” to participate more fully in the program.
Methods: To this end, we compared the posting
frequency among three strategies: (1) students and
tutors had an off-site meeting to promote face-to-face
communication during the course, (2) several classes
were allowed to watch the discussion in other classes
in the second half of the course, (3) three classes (5 –
6 students each) in one topic were combined into one
class (16 students) in the second half.
Results: No meaningful effects were observed for
strategies (1) or (2). However, the posting frequency
increased 50 % for strategy (3).
Conclusion: Facilitation of communication among
participants was achieved by increasing the number
of student participants. We predicted that an optimal
number of students in each class in internet-based PBL
would be ~20 people.

A19-year-old man was admitted to the hospital because of severe congestive heart failure on 7 April 2000. In the previous year his case had been diagnosed as Churg-Strauss syndrome (allergic granulomatous angiitis, AGA) with bronchial asthma and mononeuritis multiplex. Echocardiography revealed the dilatation of the left ventricle (LVDd 74 mm) and impaired left ventricular systolic function (LVEF 20%). On the 21st hospital day, the irregularity of peripheral branches of left and right coronary arteries was detected by coronary arteriography. Right ventricular endomyocardial biopsy yielded little fibrosis and no infiltration of eosinophil. Although all the laboratory tests showed lower activity of AGA, steroid pulse therapy was tried and the use of steroids was tapered at intervals of two weeks. Left ventricular function was slowly improved (LVDd 60 mm, LVEF 36%). He was discharged on foot on the 71st hospital day.
