In grip strength a subject being ordered to show one-third, one-second and twothird of his own maximum value after checking his maximum, the value he shows is not always the same as the ordered value. The Discrepancy Index was determined by the grade of the difference between the ordered value mentioned above and the value showed actually.
For 2117 subjects composed of both sexes our experiment was performed.
1) The possibility of training effect for one-third and two-third of their own maximum value existed but little for one-second.
2) Up to 16 years of age the training effect increased with their physical development, but after 17 years remarkable change of their grading ability was not found.
3) There existed no relation between the experimental results of one-third value and two-third, between the left hands and the right, and between the Discrepancy Index of pre-training and post-training.
4) The larger maximum value of grip strength became, the smaller the Discrepancy Index was. Sometimes in the individuals who have larger maximum value, the more training effect was recognized.
5) The champions of weight-lifting, Kendo and volleyball showed better results than those of the control groups.

Pre- and postoperative left ventricular (LV) function was assessed by Doppler echocardiography in 95 infants who underwent open heart surgery during the past two and half years. The patients were divided into three groups: 43 patients with ventricular septal defect (VSD group), 37 with atrial septal defect (ASD group) and 15 with the tetralogy of Fallot (TOF group). Echocardiography was performed before and at an early stage after surgery (average: 11.6 days) in all cases. The forward flow velocity pattern was evaluated by Doppler echocardiography, placing the sample volume at the pulmonary vein (PV) and the LV inflow portion. At the PV, the peak velocity of the S wave during systole (p-PV_S) and the D wave during diastole (p-PV_D) in patients with ASD were significantly lower (p<0.01) postoperatively. In patients with VSD, only p-PV_D was significantly lower (p<0.05) postoperatively, showing a decrease of pulmonary blood flow. These results are thought to reflect a difference in the compliance of the left atrium between the two groups. At the LV inflow portion, the ratio of peak velocity of the wave during atrial systole to R wave on rapid inflow during diastole (A/R) was significantly lower in patients with VSD (p <0.01) postoperatively. At the same time, LV ejection fraction and fractional shortening were significantly lower (p<0.01), but these values remained within the normal range. These results suggest that LV can maintain a sufficient systolic performance against the decrease in preload and the increase in afterload as well as the improvement of diastolic function during the early period after surgery in the VSD group. In patients with ASD or TOF, there were no significant differences in parameters of LV function between preoperative and postoperative periods.

Edaravone is an agent developed as a free radical scavenger, and is useful in functional recovery of the brain after cerebral infarction. However, to the best of our knowledge no experimental studies have been made regarding the effect of edaravone on cerebral protection during aortic arch surgery. We investigated the pharmacological effect of edaravone experimentally, through selective cerebral perfusion under deep hypothermia. Twelve adult dogs (body weight 14.8±2.0 kg) were used, and selective cerebral perfusion was performed under hypothermic circulatory arrest of 20°C for 120 min at 5 mg/kg/min, which was half the usual flow volume of cerebral perfusion. Group E (n=6) received 3 mg/kg edaravone for 30 min at the start of both selective cerebral perfusion and rewarming of the body, while Group C (n=6) received no drugs. Somatosensory evoked potential (SEP) was measured, and so were blood pressure, body temperature, pH level, oxygen partial pressure, and blood flow in the cerebral tissue. Histopathological investigations were also performed. In Group E, complete SEP recovery was observed in all dogs, while in Group C, complete SEP recovery was observed in only 2 dogs (33%) (p=0.014). A statistically significant difference was also observed in cerebral tissue pressure (p=0.014), but not in pH level, oxygen partial pressure, or cerebral tissue blood flow. On histopathological investigation, Group C demonstrated reduced staining of Nissl granules in neurons of the cerebral cortex, and many of them presented the appearance of acute circulatory impairment while Group E demonstrated no reduction in staining of Nissl granules. In the present experimental study of selective cerebral perfusion under deep hypothermia below the safety threshold flow, edaravone was effective in cerebral protection.

Background: Although community-based training is included in medical undergraduate education in Japan, little assessment of the outcomes of community-based education programs has been performed. The aim of this study was to investigate the outcomes of a community-based education program using a mixed method.
Methods: The study design utilized both qualitative and quantitative methods (mixed method). The subjects (n = 278) were fifth-grade medical students who were involved in the program from 2008 to 2010 inclusive. We collected two types of data: a six-item pre-and-post questionnaire (quantitative) and an open-ended questionnaire (qualitative) to evaluate the impressions this experience left on the students.
Results: Pre-and-post questionnaires were completed by 263 (95%) of 278 subjects; on all items, the scores of the post- data were significantly higher than that of pre- data (P < 0.001). From the responses given by 139 respondents (total 181, 77%) in the open-ended questionnaire survey, 10 themes were extracted: 1. Inter-professional cooperation; 2. Role and cooperation among university hospitals, community hospitals, clinics, and welfare facilities; 3. Patient-centered medicine; 4. Trust-based relationships; 5. Competency in general medicine; 6. Professionalism; 7. Medical management; 8. Communication; 9. Common diseases; and 10. Long-term care.
Conclusions: We found that medical students gained four major perspectives from their experiences: Inter-professional cooperation, trust based relationships, roles of community hospitals and clinics, and patient-centered medicine, respectively. Our findings suggest this program contributed significantly to their understanding of community medicine.

Detection of the coronary artery is usually an easy procedure in the coronary artery surgery. However in cases with an intra-muscular and/or intra-fat coronary artery, it requires special skill and experience. Dissection of epicardial adipose tissue and/or muscle along the epicardial groove is a common procedure to reach such coronary artery in conventional CABG (C-CABG). Recently, off-pump CABG (OPCAB) has become a standard operation, and detection of such a coronary artery is difficult under the beating heart. Then conversion to the C-CABG becomes necessary to avoid ventricular rupture. We report a new procedure to easily detect such a coronary artery in OPCAB, using an ultrasonic Fowmeter used in neurosurgery. Because the tip of the probe is small (2mm in diameter) and flexible, its handling is quite similar to that of the micro-blade knife. Furthermore, audiable Doppler flow sound allows detection and dissection of the coronary artery without looking away from the operative field to check the coronary flow. In our case, use of the instrument enabled us to detect the anterior descending branch of the left coronary artery which was very deep in adipose tissue. Therefore, application of this ultrasound instrument is beneficial in OPCAB with an intra-muscular and/or intra-fat coronary artery.

We performed combination therapy with modified oxaliplatin/l-LV/5-FU (mFOLFOX) in a patient with recurrent colorectal cancer who had peritonitis carcinomatosis. In this patient, mFOLFOX therapy resulted in disappearance of ascites and a decrease in carbohydrate antigen 19-9 (CA19-9), and improved quality of life (QOL) of the patient. This 62-year-old man was diagnosed with ascending colon cancer and metastatic cancer of the liver. Right hemicolectomy and right hepatic lobectomy were performed. We had started to treat with TS-1 in ambulatory care, however, he had peritonitis carcinomatosis with massive ascite reservoir on CT and peritoneal dissemination after a half year postoperatively. Furthermore, his ECOG Performance Status (PS) was rated as level 3. Therefore, we performed puncture of ascites and palliative mFOLFOX6 therapy. After ten courses, ascites and abdominal induration had disappeared and PS recovered to level 1. At present, CPT-11/l-LV/5-FU (FOLFIRI) are being administered for peripheral neuropathy and metastatic tumor associated with mFOLFOX6. The patient is spending his daily life satisfactory after FOLFIRI without abdominal swelling or ascites, and thus mFOLFOX6 may be an option for palliative therapy against massive ascites in patients with advanced colorectal cancer. The usefulness of palliative mFOLFOX6 therapy for patients with massive ascites should be evaluated in a well-designed clinical trial.Palliat Care Res 2008; 3(2): 316-320

Effects of taurine on the functions of the body and metabolism with 3km running upon taking a diet, which is constituted of lowest possible amount of carbohydrate and highest possible amount of fat and protein, were investigated in 25 male and female subjects of age thirties by double blind test method. The results were as follows
1) Taurine administration (T. A.) proved to inhibit the degree of increase in heart rate and increase the maximal degree of pulse pressure in response to 3 km running.
2) T. A. proved to inhibit the degree of increase in serum creatine kinase isozyme MB (CK-MB) activities and CK-MB/CK ratio.
3) T. A. proved to inhibit the decrease of serum total protein values immediately before running and in the following morning. Similar trends in terms of the particuler times were observed, too, in the case of the degree of decrease of serum triglycerides values.
4) T. A. seemed to accelerate the utilization of saturated fatty acids especially.
5) Three kilometer running seemed to increase in serum taurine concentrations from several hours after running to the morning immediately after running.

We investigated the effects on medical education of early exposure of undergraduate students to a summer camp for children with asthma. An objective evaluation by the editorial staff found final improvements in the following areas (in descending order of frequency): learning of basic medical behavior (91% of students); cooperative attitude of medical staff in general treatment with the patient and the patient's family (88%); understanding of childhood growth and development (80%); knowledge of childhood asthma (69%); and mastery of basic techniques for therapy and examination (41%). The differences in the ratio of improvement (%) before and after visiting the camp, were (in descending order of frequency): cooperative attitude of medical care staff in general medical treatment with the patient and the patient's family (47%); understanding of childhood growth and development (45%); knowledge of childhood asthma (38%); learning of basic medical manner (34%); and mastery of basic techniques for therapy and examination (25%). These findings suggest that a summer camp is useful for exposing undergraduate medical students to children with asthma and is effective for helping them understand patients and family-oriented pediatric medicine.

BACKGROUND/AIMS: Recent developments in analytical techniques including next-generation sequencing have clarified the correlation between intestinal microbiota and inflammatory bowel disease. Fecal microbiota transplantation (FMT) for patients with ulcerative colitis (UC) is proposed as a potential approach to resolving their dysbiosis; however, its safety and efficacy have not been confirmed. This single-arm, open-label, non-randomized study aimed to evaluate the safety and efficacy of FMT for Japanese patients with UC as the first registered clinical trial in Japan. METHODS: We enrolled 10 patients with active UC despite medical therapy. The donors were the patients' relatives and were carefully screened for infectious diseases. Fecal material was administered via colonoscopy, and the primary endpoint was the presence or absence of serious adverse events related to FMT. The secondary endpoint was a change in partial Mayo score at 12 weeks post-FMT. Scores ≤2 were considered a clinical response. Fecal samples were collected to follow changes in gut microbiota, while extracted complementary DNA were analyzed by a next-generation sequencer. We obtained written informed consent from all patients and donors. This study was approved by our Institutional Review Board and is registered in the University hospital Medical Information Network (UMIN) Clinical Trials Registry (UMIN 000012814). RESULTS: Five patients with moderate disease and five with severe disease were enrolled. No severe adverse effects were observed. One patient achieved clinical response; however, none of the patients' microbiota diversity recovered to the donor levels. CONCLUSIONS: The use of single FMT for UC was safe; however, we failed to show its clinical efficacy and potential to change the intestinal microbiota.
