Abstract
This study examined the effects of the time of conducting a combined physical and cognitive exercise program on cognitive functions and the mood of older adults. We randomly assigned 17 participants (8 men, 9 women, age 73,24±3,75) to the morning group (AM Group), 18 (8 men, 10 women, age 73,11±4,84) to the afternoon group (PM Group), and they completed a 12-week, dual-task exercise program in the morning or the afternoon, respectively. Moreover, the waiting-list control group consisted of 12 participants (6 men, 6 women, age 73,25±5,93). The cognitive functions and the mood of the participants were assessed before and after the program by using the Neurobehavioral Cognitive Status Examination, and the short version of the Profile of Mood States, respectively. As a result, the exercise program conducted in the afternoon had broader effects on cognitive functions (increased Repetition and Memory) than in the morning (increased Repetition), or the waiting-list control group (increased Judgment). Moreover, the program in the afternoon tended to reduce Anger-Hostility, and Fatigue. In conclusion, conducting the exercise program in the afternoon might be more effective for improving cognitive functions and the mood of older adults than in the morning. However, there was heterogeneity between the groups despite the randomization. Therefore, we suggest conducting a more rigorously controlled study using a larger sample to validate these findings.

Abstract
Summary
Objectives
: We introduce “Mobile Nurse" (MN) - an emerging platform for the practice of ubiquitous medicine.
Methods
: By implementing in a dynamic setting of daily life the patient care traditionally provided by the clinical nurses on duty, MN aims at integral data collection and shortening the response time to the patient. MN is also capable of intelligent interaction with the patient and is able to learn from the patient's behavior and disease sign evaluation for improved personalized treatment.
Results
: In this paper, we outline the most essential concepts around the hardware, software and methodological designs of MN. We provide an example of the implementation, and elaborate on the possible future impact on medical practice and biomedical science research.
Conclusions
: The main innovation of MN, setting it apart from current tele-medicine systems, is the ability to integrate the patient's signs and symptoms on site, providing medical professionals with powerfultools to elucidate disease mechanisms, to make proper diagnoses and to prescribe treatment.

Abstract
A 57-year-old man was admitted with a type 2 (ulcerated with clear margin) cancer in the cecum. Contrast-enhanced CT showed that the superior mesenteric vein was anterior to the superior mesenteric artery, and the patient was suspected of having intestinal malrotation. A laparoscopic-assisted ileocecal resection was performed. At operation, the cecum and the transverse colon passed through the root of the mesentery behind the superior mesenteric artery with the duodenum. Therefore, this was thought to be a reversed-type intestinal malrotation. After the operation, 3D-CT colonography with duodenography images were reconstructed to retrospectively confirm the diagnosis of a reversed malrotation. These images clearly demonstrated the abnormal anatomy and overall orientation of the intestine. Patients with a reversed intestinal malrotation and concurrent cecal cancer are extremely rare. Herein, we present a patient who underwent a laparoscopic-assisted ileocecal resection for cecal cancer that presented concurrently with a reversed intestinal malrotation.

Abstract
We experimentally demonstrate Cooper pairs' drastic enhancement of the band-to-band radiative recombination rate in a semiconductor. Electron Cooper pairs injected from a superconducting electrode into an active layer by the proximity effect recombine with holes injected from a p-type electrode. The recombination of a Cooper pair with p-type carriers dramatically increases the photon generation probability of a light-emitting diode in the optical-fiber communication band. The measured radiative decay time rapidly decreases with decreasing temperature below the superconducting transition temperature of the niobium electrodes. Our results indicate the possibility to open up new interdisciplinary fields between superconductivity and optoelectronics.

Abstract
We experimentally prepare bi-photon mixed states in polarization employing an entangled-classical hybrid photon emitter which can properly model solid-state entangled photon sources with uncorrelated background photons. Polarization-uncorrelated photon pairs in totally mixed (TM) states are embodied with classical thermal radiation, while the polarization-entangled ones in a Bell state are generated by conventional parametric down conversion. The bi-photon states generated from the hybrid photon emitter are characterized in terms of a linear entropy-tangle plane, which reveals the formation of two-qubit Werner states. We also propose a direct way for evaluating the Werner states by means of minimal coincidence counts measurements. This simple method can be widely applicable in examining the bi-photon states from solid-state entangled photon sources, in which the polarization-entangled photon pairs have temporal correlation while the background photons in the TM states do not.

Abstract
OBJECTIVES To examine in patients with mood disorders the relationship of age at onset with the location and degree of MRI-defined brain hyperintensities. METHOD Fifty-two patients diagnosed as having mood disorders and 14 controls participated in the study. Brain MR images were analyzed according to semiquantitative ratings for the anatomical distribution and severity of T2-weighted hyperintensities. We compared these hyperintensities among the three age- and sex-matched groups of late-onset mood disorder patients (LOM), early-onset mood disorder patients (EOM), and controls. The time since the onset of disorder was significantly longer in the EOM than in the LOM group. We also conducted linear multiple regression analysis using the severity of hyperintensities as dependent variable to determine whether the clinical features correlate with vascular pathology. RESULTS As for deep white matter hyperintensity (DWMH), LOM exhibited higher ratings than EOM; as for brain areas, significant between-group differences were detected in the bilateral frontal areas and in the left parieto-occipital area. No significant difference was observed between EOM and controls. As for periventricular hyperintensity, there was no difference among the three groups. We obtained a significant regression model to predict DWMH ratings; age, number of ECTs, and LOM were selected as significant variables. CONCLUSION The present study suggests that the time since the onset of disorder does not affect the development of white matter lesions, but that white matter lesions are associated with late-onset mood disorders. The frontal areas and the left parieto-occipital area would be important for the development of late-onset mood disorders.

Abstract
OBJECTIVES To explore neurobiological risk factors for major depressive disorder (MDD) and adjustment disorder in cancer patients by examining regional brain metabolism before psychiatric manifestation using positron emission tomography and by prospectively observing depressive and anxiety symptoms. METHOD Cancer patients who showed no psychiatric symptoms when they underwent 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) were followed up for one year using the Hospital Anxiety and Depression Scale (HADS). Fourteen patients who showed high HADS scores and 14 patients who showed low HADS scores were assessed by a psychiatrist 2 years after the PET scan and grouped into the deterioration group (n=10) and the no-change group (n=9). 18F-FDG PET images were analyzed to examine the difference in local brain glucose metabolism between the two groups. RESULTS The deterioration group showed a decreased glucose metabolism in the right medial frontal gyrus (BA6) and an increased glucose metabolism in the right posterior cingulate (BA29), right anterior cingulate (BA25), left subcallosal gyrus (BA25), and left caudate compared with the no-change group. CONCLUSION Cancer patients who later developed MDD or adjustment disorder showed regional brain metabolic changes. These regions may be associated with vulnerability to the onset of MDD or adjustment disorder in cancer patients.

Abstract
Recalled evaluation of headache intensity is often affected by several factors. Recently, computerized ecological momentary assessment (EMA) has been developed to avoid such problems as recall bias. Here, we compared recalled headache intensity with momentary headache intensity using EMA in tension-type headache (TTH). Forty patients with TTH wore watch-type computers for 1 week to record momentary headache intensity and also rated their headache intensities by recall. We calculated intraclass correlation coefficients between recalled headache intensity and indices from EMA recordings in the whole study population and in two subgroups divided by variability of momentary headache intensity. The results showed that consistency and agreement of momentary and recalled headache intensity were low, and this was especially marked in the subjects whose headache varied widely. These observations suggested that variability of headache intensity may affect recall of headache intensity and this should be taken into consideration in both clinical and research settings.

Abstract
A 74-year-old man who had previously undergone prosthetic graft replacement of the total aortic arch using the elephant trunk technique and of the abdominal aorta was admitted to our hospital for surgical treatment of descending aortic aneurysm. Computed tomography (CT) on admission revealed descending aortic aneurysm of 6.5 cm in diameter, and the previously placed prosthetic graft was detected in the aneurysm. Surgery for the descending aorta was performed under femoro-femoral partial bypass. During the operation, a balloon occlusion catheter introduced through the right brachial artery into the 'elephant trunk' graft was inflated before the aneurysm was opened, then the previously placed prosthetic graft was cross-clamped and the descending aorta was replaced with a new prosthetic graft with usual fashion. The postoperative course was uneventful.

Abstract
A 34-year-old man with Marfan syndrome was admitted to our hospital for surgical treatment of aortic regurgitation due to annuloaortic ectasia. He had no history of bleeding complications. Preoperative investigation revealed a slight prolongation of an activated partial thromboplastin time, which went unnoticed. He underwent aortic root replacement with a composite valve graft. During the operation, he had excessive bleeding due to coagulopathy after the termination of cardiopulmonary bypass, and needed a large amount of blood transfusion to obtain hemostasis. Before his discharge from our hospital, he was diagnosed as mild hemophilia A because of the decline in his factor VII level. To our knowledge, there has been no published case of cardiac operations in Marfan syndrome with hemophilia A.

Abstract
A 60-year-old man was admitted to another hospital because of chest oppression on effort. Chest X-ray showed radiographic evidence of a right aortic arch and double vessel coronary artery disease with 50% stenosis in the left main trunk was diagnosed by coronary angiography. He was transferred to our institute for surgical treatment of angina pectoris. Preoperatively, multi-detector row computed tomography (CT) was performed and it revealed a right aortic arch and an aberrant left subclavian artery with narrow left internal thoracic artery. A right internal thoracic artery was well demonstrated. Therefore, conventional coronary artery bypass grafting using a right internal thoracic artery and a saphenous vein graft was performed and his postoperative course was uneventful.

Abstract
OBJECTIVE To examine the clinical effects of electroconvulsive therapy (ECT) on depressed patients with medication treatment failures, we investigated the alterations in hypothalamic-pituitary-adrenocortical (HPA) function and regional cerebral metabolism rate of glucose (rCMRGlu) after ECT in these patients. METHOD Before and after ECT, the combined dexamethasone/corticotrophin-releasing hormone (DEX/CRH) test was administered to seven patients who were referred for ECT. In the same patients, (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) was also assessed. RESULTS Cortisol response in the DEX/CRH test significantly decreased after a successful ECT. A significant hypometabolism in various frontal regions and hypermetabolism in the parietal regions of these patients when compared with controls remained after ECT. CONCLUSION Depressed patients who failed trials of antidepressant medication showed a remission with ECT that was accompanied by resolution of HPA dysregulation. However, measures of cerebral brain metabolism did not resolve.

Abstract
A 51-year-old man was admitted to our hospital because of dyspnea. Coronary angiography revealed triple vessel disease and echocardiography demonstrated severe mitral regurgitation with poor left ventricular function. Under a diagnosis of ischemic mitral regurgitation, on-pump beating mitral annuloplasty and coronary artery bypass grafting using the normothermic retrograde continuous coronary sinus perfusion of oxygenated blood was performed in order to prevent reperfusion injury. The patient was easily weaned from cardiopulmonary bypass and his postoperative course was uneventful. Because of the advantages of this procedure (e.g., no reperfusion injury, testing of the mitral valve repair is done in real physiologic conditions with beating tonus), on-pump beating heart surgery seems a good surgical option for ischemic mitral regurgitation with poor left ventricular function.

Abstract
A 32-year-old man with Marfan syndrome was admitted to our hospital for detail examination of congestive heart failure. Doppler echocardiography showed severe mitral regurgitation due to prolapse of posterior mitral leaflet. Annuloaortic ectasia without aortic regurgitation was also detected by aortography. Considering the future operative need for aortic root and ascending aorta, we performed mitral valve replacement with a mechanical valve and preventive concomitant aortic root replacement with a composite valve graft. His postoperative course was uneventful. Optimal surgical treatment of mitral regurgitation and annuloaortic ectasia in Marfan syndrome is controversial because the underlying connective tissue defect theoretically might compromise repair durability. Several surgical options for mitral regurgitation and annuloaortic ectasia in Marfan syndrome are discussed.

Abstract
We report a case of multiple coronary artery bypass grafting (CABG) via a left thoracotomy without cardiopulmonary bypass. A 54-year-old female with unstable angina pectoris associated with left main trunk disease underwent emergency CABG. Because the patient had a history of total arch and aortic root replacement due to type A aortic dissection, a left thoracotomy approach was selected. The proximal end of the Y-shaped saphenous vein graft was anastomosed to the left subclavian artery, rather than to the descending aorta, owing to the remaining aortic dissection. The distal end of the Y-shaped saphenous vein graft was anastomosed to the left anterior descending artery and the posterolateral branch without cardiopulmonary bypass. The postoperative course was uneventful. The results of this surgery seem to indicate that off-pump CABG via a left thoracotomy is a viable technique, especially for patients undergoing repeat CABG.

Abstract
A 48-year-old woman admitted with progressive dyspnea had previously been diagnosed with systemic lupus erythematosus, antiphospholipid syndrome, and chronic renal failure, and had undergone mitral valve replacement with a Carpentier-Edwards pericardial bioprosthesis for mitral insufficiency 9 years before. She suffered a cerebral infarction 5 years earlier, despite appropriate anticoagulant therapy. On admission, echocardiography showed severe bioprosthetic stenosis. Repeat mitral valve replacement was conducted using a Mosaic bioprosthesis. On postoperative day 2, when heparinization was commenced, she suddenly had an epileptic fit. She also developed ischemic necrosis of the fingers and toes, considered secondary to microthrombosis. Aspirin was administered and heparin replaced by warfarin sodium. Necrosis gradually disappeared, and she was discharged 3 months after surgery. The original bioprosthesis showed degenerative changes with significant thrombus formation on cusps, thought to be mainly due to her hypercoagulable state. Considering the thrombophilic tendency in patients with antiphospholipid syndrome, strict management of anticoagulant therapy is required.

Abstract
BACKGROUND Atrial transport and atrial natriuretic peptide secretion is severely reduced from normal after the maze III procedure. To improve these factors, we developed a bilateral appendage-preserving maze procedure (BAP-maze). METHODS Forty-six patients with chronic atrial fibrillation who underwent the BAP-maze procedure were compared with 40 patients who underwent the maze III procedure. The ratio of the peak velocity of the A and E waves of transmitral flow (transthoracic pulsed Doppler echocardiography), the left atrial appendage ejection fraction (transesophageal echocardiography), and the atrial natriuretic peptide secretory reserve during treadmill exercise test were measured at 6 months postoperatively. RESULTS Sinus rhythm was restored in 44 patients (95.7%) by the BAP-maze procedure and in 39 patients (97.5%) by the maze III procedure. The ratio of the peak velocity of the A and E waves was 0.52 +/- 0.22 in the BAP-maze group and 0.25 +/- 0.19 in the maze III group (p < 0.0001). The left atrial appendage ejection fraction was 44.7% +/- 11.5%, and the atrial natriuretic peptide secretory reserve was greater in the BAP maze group (p = 0.037). CONCLUSIONS The BAP-maze procedure improved atrial transport and atrial natriuretic peptide secretion as well as simplifying the maze operation, without decreasing its effectiveness against atrial fibrillation.

Abstract
The purpose of this study is to examine the relationship between psychological factors, regional brain activity and natural killer cell activity (NKA). Eight patients with malignant diseases were studied by FDG-PET under a resting condition. NKA and degree of anxiety and depression were measured using Taylor's manifest anxiety scale (MAS) and Zung's self-rating depression scale (SDS). Linear correlation of NKA and psychological measures to the regional brain metabolism in cancer patients was examined using statistical parametric mapping (SPM). Positive linear correlation between NKA and regional metabolic rate ratios was identified in the visual association cortex, anterior cingulate gyrus (CG) and sensorimotor area, and negative correlation was identified in the inferolateral prefrontal cortex (ILPFC), prefrontal cortex (PFC), orbitofrontal cortex (OFC) and anterior temporal cortex. Positive linear correlation to the MAS score was identified in the visual association cortex, anterior CG, primary sensorimotor area and the posterior parietal cortex, and negative correlation was detected in the ILPFC, PFC, OFC and anterior temporal cortex. The NKA and MAS scores positively correlated with each other (p<0.001). The result might serve as supporting data for a hypothesis that psycho-immune interaction is also mediated by the cerebral cortex and limbic system.

Abstract
BACKGROUND The aim of this study was to investigate influences of depressive states, chemotherapy and existence of remaining tumors on the regional brain activity of cancer patients. MATERIAL AND METHODS Positron emission tomography with 18F-fluorodeoxyglucose was performed on 21 patients with various types of cancer. Their brain images were compared to 10 age- and gender-matched control data using statistical parametric mapping (SPM). The patients were subgrouped into the with and without depression based on the scores on Zung's self-rating depression scale (SDS), with and without previous chemotherapy, and with and without existence of remaining tumors. RESULTS Significant metabolic reduction was detected in the cingulate gyrus, prefrontal, dorsolateral prefrontal, temporoparietal cortices and basal ganglia in cancer patients. These findings were close to known lesions of major depression. Intra-group comparisons showed that these hypometabolic findings were associated with the depth of depressive state. Influences of chemotherapy and remaining tumors on the cerebral cortex seemed to be weaker than that of psychological factors. CONCLUSIONS The present pilot study suggests that frontal hypoactivity commonly seen in cancer patients is likely to be associated with depression rather than chemotherapy or remaining tumors. A brain mapping technique might be useful in evaluating neuropsychiatric problems in cancer patients.

Abstract
We report a case of 52-year-old woman with primary antiphospholipid syndrome who developed mitral insufficiency and chronic renal failure. Continuous ambulatory peritoneal dialysis was started preoperatively due to thrombocytopenia that was aggravated by hemodialysis. Mitral annuloplasty was performed since the mitral valve was not severely damaged. Her postoperative hemodynamics were stable, and anticoagulant therapy was controlled easily. She recovered from severe thrombocytopenia while on continuous ambulatory peritoneal dialysis. Valvular heart disease is a well known feature of primary antiphospholipid syndrome, and there have been several reports about valve replacement in patients who had antiphospholipid syndrome with or without systemic lupus erythematosus. However, valve repair has been reported in only a few such patients. We believe that valve repair is better than valve replacement in patients with antiphospholipid syndrome because of its hypercoagulable tendency. In addition, it seems that continuous ambulatory peritoneal dialysis is a suitable method for the perioperative management of patients with antiphospholipid syndrome who suffer from chronic renal failure as well as thrombocytopenia, and require cardiac surgery under cardiopulmonary bypass.

Abstract
The use of selective cerebral perfusion with a heparin-coated extracorporeal circuit has not been reported. We developed a unique extracorporeal circulation system that can be used for selective cerebral perfusion based on an existing heparin-coated circuit with a centrifugal pump for general open-heart surgery and a heparin-coated oxygenator without venous drainage by gravity. Between July 1994 and December 1999, this system was used for 12 patients undergoing surgery for true aortic arch aneurysm. The dose of heparin used was reduced to maintain minimum activated clotting time above 300 sec during extracorporeal circulation. One patient suffered a stroke, and one patient had transient postoperative neurologic deficit. One patient died suddenly of ventricular arrhythmia on the 11th postoperative day. The circuit remained thrombus-free. Selective cerebral perfusion with a heparin-coated bypass circuit was safe and very easy to perform after a simple modification of a standard circuit for open-heart surgery.

OBJECTIVE To examine the effectiveness of Ninjin Yoei To (NYT; Ren-Shen-Yang-Rong-Tang in Chinese medicine; Kotaro Pharmaceutical Co., Ltd., Osaka, Japan), one of the traditional herbal medicines, against lung carcinoma. SETTING The Nursing Center Himawari DESIGN, PATIENT, AND PREPARATION: The regular dosage of NYT (15 g/d) was prescribed for 7 weeks to one elderly patient with lung carcinoma. The daily standard dose of NYT is prepared from dried extract obtained from 12 crude natural substances, ginseng, cinnamon bark, Japanese angelica root, astragalus root, peony root, citrus unshiu peel, rehmannia root, polygala root, atractylodes rhizome, schisanda fruit, poria sclerotium, and glycyrrhiza. NYT is certified by the Japanese Ministry of Health and Welfare. RESULTS The tumor marker levels (CEA and CA19-9) decreased and the scores of yin-yang and xu-shi inverted from negative and positive during 7 weeks. The patient's cough disappeared and her appetite recovered. CONCLUSION NYT has a positive effect on life expectancy for patients with malignancy. The diagnostic scoring system in yin-yang and xu-shi and prescription of Chinese herb may be available to gain control over a patient's health.

Abstract
BACKGROUND The aim of this study was to investigate the clinical features of psychosomatic disorders in Japan. METHODS A total of 1,432 outpatients (515 males and 917 females; 9-95 years of age, mean age 36) attending a psychosomatic clinic for the first time were assessed by the DSM-III-R or DSM-IV semistructured interview. RESULTS Major ICD-10 diagnoses found were eating disorder, other anxiety disorders, autonomic nervous dysfunction, somatoform disorders, and irritable bowel syndrome. The most frequent diagnosis on the DSM-III-R and DSM-IV axis I was 'somatoform disorders not otherwise specified', followed by bulimia nervosa, 'depressive disorder not otherwise specified', anorexia nervosa, conversion disorder, major depression or depressive disorder, 'panic disorder with agoraphobia', and 'psychological factors affecting physical or medical condition'. On axis II, 11-17% of the patients met the criteria for personality disorder. On axis IV, 78-80% had mild or moderate psychosocial stress; major psychosocial and environmental problems classified by the DSM-IV were the problems with primary supports and occupation. CONCLUSIONS The results seem to reinforce the belief that the diagnoses on the DSM-III-R and DSM-IV axis I are inadequate for describing psychosomatic phenomena. A new diagnostic system in combination with the multidimensional assessments by the DSM-III-R and DSM-IV is needed to form the common guidelines of diagnoses and therapies in psychosomatic medicine.

Abstract
OBJECTIVE To examine the effectiveness of Mao-bushi-saishin-to (Ma-Huang-Fu-Zi-Xi-Xin-Tang in Chinese medicine) (Tochimototenkaido Co. Ltd., Osaka, Japan), one of the traditional herbal medicines, against resistant bacterial infection. SETTING The Nursing Center Himawari, Izumo, Japan DESIGN, PATIENT, AND PREPARATION: Half of the standard dose of Mao-bushi-saishin-to was prescribed for 7 days to one elderly patient with fever and positive C-reactive protein (CRP) levels suffering from drug resistant Pseudomonas aeruginosa. The daily standard dose of Mao-bushi-saishin-to is prepared from 1200 mg of dried extract obtained from three crude drugs, Ephedrae Herba (4 g), Asiasari Radix (3 g), and Aconiti Tuber (1 g). It is certified by the Japanese Ministry of Health and Welfare. RESULTS The patient's fever and CRP level returned to normal levels. CONCLUSIONS In cases in which the fever does not fall in response to antibiotics for at least 3 days, half of the standard dose of Mao-bushi-saishin-to for 7 days might be worth trying to induce remission, especially for elder patients.

Abstract
OBJECTIVE Radial artery suitability in coronary artery bypass grafting was assessed using duplex ultrasonography. SUBJECTS AND METHODS The vascular condition along the entire radial artery was scanned in 55 patients, measuring the internal diameter and mean flow velocity at the wrist (distally), after ulnar artery branching (proximally), and midway between these 2 points (medially). Distally along the radial and ulnar arteries, the mean flow velocity was determined before and after radial artery occlusion. RESULTS Atherosclerotic changes were detected in 4 patients. The internal diameter was 3.1 +/- 0.4 mm proximally, 2.7 +/- 0.3 mm medially, 2.4 +/- 0.4 mm distally. The distal flow velocity was 0, and a reverse flow (peak velocity: 11.3 +/- 6.0 cm/s) was observed after the occlusion test in patients with an intact palmar arch, their mean flow velocity, 21.1 +/- 8.9 cm/s, and flow distally along the ulnar artery 58.0 +/- 23.4 ml/min, were higher after the occlusion test than before it 14.7 +/- 6.7 cm/s mean flow and 38.1 +/- 15.9 ml/min distally. This was not observed in patients with an interrupted palmar arch. In 15 patients, radial arteries could not be used because of their small internal diameter, lack of a radial artery, poor vascular condition, or an interrupted palmar arch evaluated using duplex scanning. CONCLUSION Reliable noninvasive assessment of radial artery anatomy and palmar arch continuity is thus possible using duplex ultrasonography.

Abstract
Photic Feedback treatment of a patient diagnosed with Miller Fisher syndrome has resulted in the rapid and permanent remission of symptoms. During Photic Feedback treatment, the CD20 appeared to be slightly increased. This may have been associated with changes in humoral immunity. The present clinical observation of a single patient suggests that Photic Feedback treatment should be investigated as a possible adjunct therapy for patients who suffer from polyneuropathies, such as Miller Fisher syndrome, within a carefully controlled clinical trial.

Abstract
The failure of patients to comply with treatment regimens recommended by their physicians is a significant clinical problem. Researches on the assessment of compliance have, however, been precluded by methodological difficulties such as lack of adequate measures. The purpose of this study was to develop a self-administered questionnaire to evaluate drug compliance. First, questionnaire containing a 52-items complied by two doctors, a pharmacist and a nurse, was tested on 81 outpatients, all volunteers, attending the departments of psychosomatic medicine and internal medicine. Four items were temporarily removed for later analysis because they directly inquired about drug compliance (drug compliance items). The other 48 items were analyzed and three factors consisting of 26 items were further studied: expectation on taking medicine, rejection to taking medicine and seeking knowledge of drugs. Chronback's alpha coefficients representing internal consistency of the three factors were sufficiently high (ranging from .75 to .84). Furthermore, we preformed a simplified pill count to validate the 4 drug compliance items. There was a weak to moderate correlation between the result of pill count and each of 4 drug compliance items. A new self-administered questionnaire of 30 items was thus developed and named the Drug Compliance Scale.

Abstract
The purpose of this study was to investigate psychological factors affecting drug compliance in the department of psychosomatic medicine. Seventy-four outpatients were asked to answer a battery of self-administered questionnaire including the Drug Compliance Scale (DCS) that we had recently developed and other questionnaire evaluating psychological and vegetative symptoms, self-efficacy and attributional styles on the promotion of health and personality closely related to interpersonal relationships. Results of path analysis indicated that attributional styles and self-efficacy mainly affected three factors of DCS such as expectation on taking medicine, rejection to taking medicine and seeking knowledge of drugs, through which they influenced drug compliance, and also indicated that personality and self-efficacy mainly affected the stability of mood state, suggesting a further influence on drug compliance.

Abstract
The relationship between psychosocial factors and the occurrence and aggravation of peptic ulcer was studied in elderly people. Thirty-nine (14 male) ulcer patients and 79 (30 male) elderly people aged 65 years and over and living in the community were tested. Information on health status, medication, lifestyle, and psychosocial status was obtained by means of interviews using a questionnaire and from the clinical records of the ulcer patients. The same questionnaire was distributed to the residents. Logistic regression analysis adjusting for age disclosed that peptic ulcer was significantly associated with having an occupation and low exercise practice in men. However, the relationship weakened below statistical significance after adjusting for some physical risk factors besides age. Low education was significant but low instrumental support fell short of statistical significance with peptic ulcer in women even after adjustment for several physical risk factors besides age. Thus, the specific psychosocial factors might be independently associated with the occurrence and aggravation of peptic ulcer in at least elderly women.

Abstract
UNLABELLED We examined whether heparin-coated (HC) circuits can improve the operative results in patients with chronic renal insufficiency. SUBJECTS AND METHODS Elective cardiac surgery was performed in 24 patients with a serum creatinine (Cr) level of at least 1.5 mg/dl. Uncoated circuits were used in 12 patients, and HC circuits were used in 12 patients. The results of surgery were compared between the two groups. RESULTS The mean preoperative Cr concentration was significantly higher in the HC group (2.3 vs 1.8 mg/dl). The heparin doses, protamine dose, and activated clotting times were significantly lower in the HC group. The mean blood loss was also less, although this difference was not significant. The postoperative increase in the Cr level was small in the HC group (2.3-->2.5 mg/dl) compared to that in the noncoated group (1.8-->2.3 mg/dl). Postoperative dialysis was not required in the 5 patients in the HC group with a preoperative Cr clearance less than 20 ml/min. CONCLUSION HC circuits and low-dose heparin can be used to maintain renal function after cardiopulmonary bypass, even in patients with severe kidney disease.

Abstract
BACKGROUND We examined the safety of reduced systemic heparinization during heparin-coated cardiopulmonary bypass by measuring coagulofibrinolitic indices, including fibrinopeptide A, which directly reflects fibrinogenesis. METHODS Twenty-four patients who had elective cardiac operations were perfused using a circuit coated with covalently bonded heparin. Twelve patients received 300 U/kg of heparin and the remaining 12 patients received 150 U/kg. Blood was obtained for the measurement of thrombin-antithrombin III complexes, fibrinopeptide A, plasmin-alpha 2 plasmin inhibitor complexes, and D-dimer preoperatively; after heparin administration; 10, 60, and 90 minutes after the start of bypass; after protamine administration; and 1, 3, 6, 12, and 24 hours after the end of bypass. RESULTS Preoperative, intraoperative, and postoperative variables including postoperative bleeding were not significantly different between the two groups. Further, there were no complications in either group. No significant differences between the two groups were noted for any hematologic index at any time point. CONCLUSIONS Reduced systemic heparinization combined with a heparin-coated cardiopulmonary bypass circuit is biochemically and clinically safe but does not reduce postoperative bleeding.

Abstract
Postoperative bleeding was examined in patients undergoing cardiopulmonary bypass with a heparin-coated circuit and low-dose heparin. Out of 150 patients who underwent cardiopulmonary bypass for longer than 90 minutes, 74 received a standard dose (300 IU/kg) of heparin with an uncoated circuit (group C) and 76 received a low-dose (150 IU/kg) of heparin with a heparin-coated circuit (group H). The coagulation and fibrinolytic systems were investigated in 24 patients. Re-opening of the chest due to bleeding was performed in 5 patients in group C (7%), but none of the patients in group H (p=0. 03). The median of blood loss in the first 12 hours after surgery was 292 ml in group C, and 216 ml in group H (p=0.006). There were no significant differences in the peak thrombin-antithrombin complex concentration between the two groups. The plasmin-alpha 2 plasmin inhibitor complex concentrations after protamine administration were 1.9 ng/ml (median) in group C and 1.1 ng/ml in group H (p=0.002). The use of heparin-coated cardiopulmonary bypass circuits with low-dose heparin suppressed the activation of fibrinolysis. This may explain the reduction in postoperative bleeding.

Abstract
To clarify the effects of ego states on anorexia nervosa (AN) and bulimia nervosa (BN), the questionnaire of the Tokyo University Egogram (TEG) with critical parent, nurturing parent, adult, free child and adapted child scales was administered to 32 female AN patients aged 14 to 32 years (mean age 20 years) and 49 female BN patients aged 14 to 33 years (mean age 23 years). The scores on the critical parent and adapted child scales for AN were significantly lower than those for BN. A multiple logistic regression analysis including all of the TEG scales, age, duration of illness and education showed that the adapted child scale significantly discriminated between AN and BN. The adaptive ego state is suggested for differentiating between the two disorders.

Abstract
We encountered a rare complication of mitral valve replacement with the CarboMedics prosthesis: a "stuck" leaflet detected by transesophageal echocardiography even though weaning from cardiopulmonary bypass had been uneventful. The patient was immediately managed without significant problems. We emphasize the importance of performing routine intraoperative transesophageal echocardiography in valve replacement as well as in valve repair, from the initial phase of operation.

Abstract
We assessed the changes in regional bone mineral density according to age and examined the relationship between various regional bone mineral densities. The study was conducted in 985 Japanese women divided into < 50-years group (n = 435) and > or = 50 years group (n = 550). The total body bone mineral density and that of the head, arm, leg, thoracic (T)-spine, lumbar (L)-spine, ribs, and pelvis were measured using dual energy x-ray absorptiometry. There was a significant generalized reduction of bone mineral density in all regions after the age of 50 years. The most marked age-related decrease was observed in the L-spine. Bone mineral densities in all regions significantly correlated to each other in both age groups, but the degree of significance varied among regions. The relationship between bone mineral density of the L-spine and that of T-spine regions was the most significant in both groups. In the < 50-years group, the correlation between bone mineral density of the pelvis and that of L-spine and T-spine was the highest, followed by that between the pelvis and the leg. On the other hand, in the > or = 50-years group, the correlation between bone mineral density of the pelvis and that of the leg was the highest, but not the L-spine or T-spine. Since spine measurements are affected by vertebral deformity and/or aortic calcification, our findings suggest the pelvis may be a useful region for screening measurements of bone mineral density, especially in older women.

Abstract
We retrospectively examined the influence of left ventricular wall thickening on myocardial injury in aortic valve replacement. Thirty-five patients who underwent aortic valve replacement in our hospital between January 1995 and July 1997 were studied. We divided these patients into 3 groups: group N (left ventricular thickness (LVT) < or = 10 mm), group H (10 < LVT < or = 15 mm), and group S (LVT > 15 mm). All patients of group S had aortic stenosis. CK and CK-MB were significantly higher and the cardiac index was significantly lower in group S than in the other groups. Intra-aortic balloon pumping was required for 50% of patients in group S, and a total dose of catecholamine above 10 micrograms/kg/min was also required for 50% of patients in this group. In the other groups, these percentages were significantly lower. Myocardial protection and postoperative care were difficult for patients with severe left ventricular hypertrophy with LVT over 15 mm in this study. Left ventricular wall thickness was a more important factor in determining difficulty with intraoperative myocardial protection than was left ventricular mass.

Abstract
We examined the effective amplitudes of alpha waves (using a mean frequency with a range of +/- 0.5 Hz), and activity of natural killer cells in six subjects, before and after a short-distance (43 km, 1 hr.) drive, and after a midnight (am 0:00-am 7:00 to 8:00) long-distance (550 km on average, for 7 to 8 hr.) drive. Following a long-distance drive, the activity of natural killer cells tended to decrease, and the effective amplitudes of alpha waves in the photic feedback period were greater than those observed during the rest period, showing that photic driving had occurred even under physically and mentally stressful conditions. However, after short-distance driving, no photic driving response occurred and activity of natural killer cells tended to increase, possibly related to mental concentration. Avoiding midnight long-distance driving may help prevent excessive stress and preserve high activity in natural killer cells.

Abstract
A 19-year-old man developed paralysis of the left arm as a result of left brachial plexus injury by a traffic accident. He underwent operation for the brachial plexus paralysis, and then severe heart failure developed postoperatively. Echocardiography revealed severe tricuspid valve regurgitation. Tricuspid valve plasty was performed 14 months after the traffic accident. The anterior leaflet of the tricuspid valve was torn and the chordae attached there were torn as well. The torn anterior leaflet was sutured directly, and the prolapsed portion of this leaflet was collected by transfer of the elongated chordae. Annuloplasty (DeVega technique) was then added. Postoperative echocardiography revealed trivial regurgitation of the tricuspid valve. Only 9 cases of successful repair of traumatic tricuspid regurgitation have been reported in Japan.

Abstract
The results of reconstruction of the aortic root performed on 9 patients by Svensson's method were examined. Nine subjects comprised 6 men and 3 women aged 23-69 years. In the preoperative diagnosis, annulo-aortic ectasia (AAE) was found in 7 cases, acute Type A aortic dissection in 1 case and AAE accompanied by chronic dissection after AVR in 1 case. Every patient underwent reconstruction by direct implantation of the right coronary artery button and interposition grafting for the left coronary artery, using a composite valve graft made of SJM valve and collagen coating artificial graft. Although one patient was lost due to multiple cerebral infarction, no marked changes were observed in other 8 patients. Angiography at short-term after operation showed no problems in the composite valve graft, and revealed good coronary arterial flow. Now, 2-62 months after operation (41 months on average), no late death occurred. On angiography of 2 cases performed after a long-term period, patency of the interposition graft was excellent. The early and late results of aortic root reconstruction by Svensson's method appeared favorable.

Abstract
OBJECTIVE Although psychological stress and smoking have been proposed as factors contributing to Graves' disease, their independent roles in the course of this disease have not been determined. We assessed the association between the course of Graves' disease and psychosocial factors by using multivariate analysis. METHODS We investigated the association between the short-term outcome of Graves' disease (assessed 12 months after the beginning of antithyroid drug therapy) and stressful life events, daily hassles, smoking, drinking habits, coping skills, and social support (before and 6 months after beginning therapy) in 230 patients (182 women and 48 men) with newly diagnosed Graves' disease, using a logistic regression model. RESULTS After adjustment for smoking, coping skills, and thyroid function, daily hassles scores in women at 6 months after beginning therapy were significantly associated with a hyperthyroid state 12 months after beginning therapy. The relative risk was 3.9 for women with higher daily hassles scores compared with women with lower daily hassles scores (95% confidence interval, 1.1 to 13.2; p < .05). Smoking was not significantly associated with a hyperthyroid state 12 months after beginning therapy in either women or men. CONCLUSIONS Chronic psychological stress is associated with the course of Graves' disease in women.

Abstract
A 60-year-old man was transferred to our hospital for blunt trauma of the chest suffered in a traffic accident. He had a weak pulse, and cardiopulmonary resuscitation was continued in the ambulance. Chest roentgenography revealed left hemothorax, and echocardiography revealed pericardial bleeding. He was immediately transported to the operating room, because of severe hypotension due to massive bleeding from the chest drainage tube. Median sternotomy was performed under stand-by cardiopulmonary bypass. There was projectile bleeding from the anterior wall of the right ventricle. The site of rupture was sutured with felt strip. A tear in the pericardium was also present at the apex. Postoperative recovery was uneventful. Fulda et al. reported that the incidence of combined pericadial and cardiac chamber rupture was 8% for those patients suffering blunt chest trauma, and that the rate of survival was less than 15% for blunt heart rupture. We have reported here successful repair of combined rupture of the right ventricle and pericardium.

Abstract
After administering 15 g/day of Ninjin-Yoei-To (NYT) for one week to healthy people whose NK activity had already been increased by physiological response, a further increase in NK activity was observed after two days. This increased level of NK activity continued during the administration of NYT for a one-week period. The maintaining and reinforcing effect on the immune surveillance system by NYT may be useful for prevention of carcinogenesis.

Abstract
In order to clarify the differences in mood states between anorexia and bulimia nervosa, the Profile of Mood States (POMS) with tension-anxiety, depression, anger-hostility, vigour, fatigue and confusion scales was administered to 32 female patients with anorexia nervosa (age range 14 to 32 years, mean age 20 years), 49 female patients with bulimia nervosa (age range 15 to 33 years, mean age 23 years) and 410 'normal' female subjects (age range 14 to 35 years, mean age 23 years). The scores on the depression, fatigue and confusion scales for both anorexia and bulimia nervosa and those on the tension-anxiety and anger-hostility scales for bulimia nervosa were significantly higher than those for the control subjects. The score on the fatigue scale for bulimia nervosa was significantly higher than that for anorexia nervosa. Moreover, the result of the multiple logistic regression analysis including all of the POMS scales indicated that the fatigue scale significantly discriminated between the two disorders. Fatigue mood appears to be a principal indicator for differentiating between the two disorders.

Abstract
OBJECTIVE Although psychological stress and smoking have been proposed as contributing factors to Graves' disease, their independent roles in the pathogenesis of this disease have not been determined. We assessed the association between Graves' disease and psychological stress and smoking by using multivariate analysis. METHODS By a matched case-control method, we investigated the association between Graves' disease and stressful life events, daily hassles, smoking, drinking habits, coping skills, and social support in 228 patients (182 women and 46 men) with newly diagnosed Graves' disease; we used the conditional maximum likelihood method. RESULTS After data were adjusted for daily hassles, smoking, drinking habits, social support, and coping skills, we found that stressful life events were significantly associated with the risk of Graves' disease in women. The relative risk was 7.7 for women with the highest stress score compared with women with the lowest stress score (95% confidence interval, 2.2 to 27, p for trend < .001). Smoking was also independently associated with the risk of Graves' disease in women. The relative risk for women with the highest number group compared with women with the lowest number group for smoking cigarettes was 5.1 (95% confidence interval, 1.0 to 27; p for trend < .001). These factors were not significantly associated with Graves' disease in men. CONCLUSIONS Psychological stress and smoking were associated with Graves' disease in women, but not in men.
