The purpose of this study was to examine the effect of active recovery between two strenuous anaerobic exercises separated by a short time interval. Eight healthy adult male volunteers (age: 24.8±1.8 yrs, height: 170.6±2.5 cm, weight : 70.1 ±2.5 kg) underwent five exercise sessions. Each session consisted of a warm-up, the first anaerobic exercise test (40 sec of exhaustive cycle ergometer exercise), a 30 min inactive (seated) or active recovery period, and a second anaerobic exercise test. During the active recovery period, subjects executed one of four different intensity pedaling tests (60, 80, 100, 120% of predetermined lactate threshold intensity) for 10 min. There were no significant differences in mean power and peak blood lactate concentration among sessions during the first anaerobic exercise test. Significant differences were found in the blood lactate concentration among sessions during the second anaerobic exercise test, and significant differences were found in mean power for the second anaerobic exercise. Optimal intensity related to the blood lactate removal rate was 83.3±7.1%LT, and that related to the working capacity recovery rate was 68.3±11.8%LT.
From these results, concerning blood lactate removal rate, it was suggested that between 80%LT and 100%LT was an effective intensity. As for performance, the effective intensity was less than 100%LT.

Erythema gyratum repens (EGR) is characterized by peculiar clinical features of a wood-grain or zebra-like appearance and rapid migration of concentric erythematous bands as a skin manifestation.
Since Gammel reported in 1952 the first case of this condition as a complication in a 60-year-old man with breast carcinoma, a large number of cases with underlying malignancies have been recorded in medical literature throughout the world. Therefore, ERG has been considered an absolute form of the paraneoplastic skin syndrome.However, Barber et al. reported a case of EGR resulting from pulmonary tuberculosis and unassociated with visceral neoplasm in 1978. Many recent studies also suggests that not all the EGR cases are definitely linked to underlying malignancies.
In this article, we describe a case of a 51-year-old man with EGR in whom no internal malignancies could be detected. We also discuss distinctions between EGR and erythema annulare centrifugum (EAC) and more complex clinical and immunopatholigic aspects of EGR, which have come to the attention of medical researchers recently.

PURPOSE: The proposed the thoracolumbar injury classification system (TLICS) for thoracolumbar injury cites the integrity of the posterior ligamentous complex (PLC). However, no report has elucidated the severity of damage in thoracic and lumbar injury with classification schemes by presence of the PLC injury. The purpose of this study was to accurately assess the severity of damage in thoracic and lumbar burst fractures with the PLC injuries. MATERIALS AND METHODS: One hundred consecutive patients treated surgically for thoracic and lumbar burst fractures were enrolled in this study. There were 71 men and 29 women whose mean age was 36 years. Clinical and radiologic data were investigated, and the thoracolumbar injury classification schemes were also evaluated. All patients were divided into two groups (the P group with PLC injuries and the C group without PLC injuries) for comparative examination. RESULTS: Fourth-one of 100 cases showed PLC injuries in MRI study. The load sharing classification score was significantly higher in the P group [7.8+/-0.2 points for the P group and 6.9+/-1.1 points for the C group (p<0.001)]. The TLICS (excluded PLC score) score was also significantly higher in the P group [6.2+/-1.1 points for the P group and 4.0+/-1.4 points for the C group (p<0.001)]. CONCLUSION: The presence of PLC injury significantly influenced the severity of damage. In management of thoracic lumbar burst fractures, evaluation of PLC injury is important to accurately assess the severity of damage.

The purpose of this study was to reevaluate the sho of goshuyuto, which has been established in an unscientific manner, and to create a new concept of the sho of goshuyuto. Eighty-four patients suffering from chronic headache were instructed to orally consume 7.5g. day of a spray-dried powder of goshuyuto (TJ-31) for 4 weeks. Before consuming the TJ-31, all subjects underwent Kampo examinations that were based on 43 diagnostic items. After the 4-week period of medication, all the subjects were classified as either responders or nonresponders. After excluding insignificant items from the 43 diagnostic items, discriminant analysis, which discriminated between responders and nonresponders, was conducted. Of the 80 subjects who completed the trial period, 57 were judged to be responders and 23 to be nonresponders. “Cold feet,” “fluid and gas retention in the stomach,” “kyokyo-kuman,” “tenderness at side of navel,” and “pulsation at abdomen” were selected by stepwise selection. The results of the discriminant analysis using these 5 items suggest that 28 subjects were misclassified and that the misclassification rate was 35%. Of the actual 23 nonresponders, 20 were accurately discriminated as nonresponders. The 5 selected items are suggested to be more useful in selecting the nonresponders than the responders. In conclusion, the empirically established sho of goshuyuto seemed to not be abele to completely explain the indication of goshuyuto. However, the inclusion of “tenderness at side of navel” and “pulsation at abdomen,” as new components comprising the sho of goshuyuto, may facilitate a more accurate indication of goshuyuto.

The aim of this study is to report the results of the workshop which was designed to define several indispensable conditions for the implementation of the compulsory clinical training. These conditions discussed include the guarantee of position and improvement of labor conditions for trainees, standard for the authorization of institutions receiving trainees, training curricula and teaching staff of institutions, and the certificate of qualification for the trainees after the compulsory training. The products of the workshop showed plans and guidelines to these conditions as seen in this paper.

The aim of this study is to report and analyze the results of a questionnaire concerning the present programs for the junior residents in the postgraduate clinical course in Japan.
A questionnaire was sent to the administrators or the persons in charge of the programs of 347 institutions including 80 university hospitals and 267 clinical training hospitalsas designated by the Ministry of Health and Welfare.
Answers to a questionnaire were returned by 271 institutions (78.1%). The results were analyzed and summarized as follows.
(1) About 95% of both university and clinical training hospitals have their own programs at present.
(2) In the substantial formula of programs, university hospitals have had straight or rotation form while the clinical hospitals have selected rotation or super rotate (comprehensive) form.
(3) The programs of university hospitals have started in majority before 1992 while those of clinical hospitals have began after 1993.
(4) The programs of university hospitals have contained the clinical training at the other departments or institutions in a significantly higher ratio compared to those of clinical hospitals.
(5) The check system for the evaluation of the programs has well functioned in half of both hospitals.
(6) For the assessment of the programs used, about half of the staffs of both university and clinical hospitals feel unsatisfactorily in their active programs.
(7) Concerning the intention to renewal or modification of their programs used, there were rather passive agreements in both university and clinical hospitals.

Since the discovery of the first strain in 1961 in England, MRSA, the most notorious multidrug-resistant hospital pathogen, has spread all over the world. MRSA repeatedly turned down the challenges by number of chemotherapeutics, the fruits of modern organic chemistry. Now, we are in short of effective therapeutic agents against MRSA prevailing among immuno-compromised patients in the hospital. On top of this, we recently became aware of the rise of diverse clones of MRSA, some of which have increased pathogenic potential compared to the classical hospital-associated MRSA, and the others from veterinary sources. They increased rapidly in the community, and started menacing otherwise healthy individuals by causing unexpected acute infection. This review is intended to provide a whole picture of MRSA based on its genetic makeup as a versatile pathogen and our tenacious colonizer.
