Abstract
We report on the nuclear dependence of transverse single-spin asymmetries (TSSAs) in the production of positively charged hadrons in polarized p^{↑}+p, p^{↑}+Al, and p^{↑}+Au collisions at sqrt[s_{NN}]=200 GeV. The measurements have been performed at forward rapidity (1.4<η<2.4) over the range of transverse momentum (1.8<p_{T}<7.0 GeV/c) and Feynman x (0.1<x_{F}<0.2). We observed positive asymmetries for positively charged hadrons in p^{↑}+p collisions, and significantly reduced asymmetries in p^{↑}+A collisions. These results reveal a nuclear dependence of TSSAs for charged-hadron production in a regime where perturbative techniques are applicable. These results provide new opportunities to use p^{↑}+A collisions as a tool to investigate the rich phenomena behind TSSAs in hadronic collisions and to use TSSAs as a new handle in studying small-system collisions.

Abstract
SummaryA segment of the inferior vena cava was replaced by an expanded polytetrafluoroethylene graft in 13 dogs. Five of them served as a control group, while the other 8 were moderately or severely defibrinogenated with subcutaneous batroxobin. Plasma fibrinogen decreased to extremely low values throughout the experiment in the defibrinogenated dogs except in the moderately treated group in which it temporarily rose to 0.72-0.87 g/1 on the first postoperative day.Scanning electron microscopic observations of the haemostatic clot formed at the anastomoses of the graft revealed no significant morphological differences in platelet adhesion and/or aggregation between the three groups. These findings confirmed that platelets play a key role in primary haemostasis during defibrinogenation.The fibrin network was slightly diminished and only short fibrin filaments could be seen in the moderately and severely defibrinogenated groups respectively. These differences in composition of the clots are discussed in relation to their haemostatic capacity.

Abstract
In order to elucidate the cause and pathology of varicose veins in the lower limb, the terminal valves of the long saphenous vein in 36 patients with varicose veins and ten control cases have been examined by light and transmission electron microscopy. Valve failure in the varicose group was thought to start with a depression in the valvular commissure and to proceed to extension of this depression and expansion of the space between the two valves. It was further thought that, in this group, reversal and tortuosity of the valve cusps, hyperplasia of the collagen fibres and irregularity of the course of elastic fibre layers represented secondary changes. In almost all cases, intimal fibrous thickening was present in the vein wall, and this was histologically similar to so-called phlebosclerosis. It was further confirmed that the degree of intimal thickening was correlated to the disease period, with greater thickening noted at the region under greater pressure load. Phlebosclerosis seemed to be proportional to the size of stress and pressure load time.

Abstract
Recent studies revealed that a substantial proportion of patients with high-risk B-cell precursor acute lymphoblastic leukemia (BCP-ALL) harbor fusions involving tyrosine kinase and cytokine receptors, such as ABL1, PDGFRB, JAK2 and CRLF2, which are targeted by tyrosine kinase inhibitors (TKIs). In the present study, transcriptome analysis or multiplex reverse transcriptase–PCR analysis of 373 BCP-ALL patients without recurrent genetic abnormalities identified 29 patients with kinase fusions. Clinically, male predominance (male/female: 22/7), older age at onset (mean age at onset: 8.8 years) and a high white blood cell count at diagnosis (mean: 94 200/μl) reflected the predominance of National Cancer Institute high-risk (NCI-HR) patients (NCI-standard risk/HR: 8/21). Genetic analysis identified three patients with ABL1 rearrangements, eight with PDGFRB rearrangements, two with JAK2 rearrangements, three with IgH-EPOR and one with NCOR1-LYN. Of the 14 patients with CRLF2 rearrangements, two harbored IgH-EPOR and PDGFRB rearrangements. IKZF1 deletion was present in 16 of the 22 patients. The 5-year event-free and overall survival rates were 48.6±9.7% and 73.5±8.6%, respectively. The outcome was not satisfactory without sophisticated minimal residual disease-based stratification. Furthermore, the efficacy of TKIs combined with conventional chemotherapy without allogeneic hematopoietic stem cell transplantation in this cohort should be determined.

Abstract
OBJECTIVE The Japanese Committee for Stentgraft Management (JACSM) was established with the aim of ensuring the safe and proper reach of commercial stent grafts following their regulatory approval. This study examines the validity of the practice standards developed by JACSM. METHODS JACSM comprises 10 associations related to endovascular treatment. Based on the practice standards developed by JACSM, the status of practising institutions, practising surgeons, supervising surgeons and the results of follow-up surveys were analysed. RESULTS In the 2.5 years following the establishment of JACSM, 298 institutions have fulfilled the practice standards. The number of practising surgeons reached 493, and the number of supervising surgeons reached 177. There were 3089 registered cases up to June 2009. The present study analysed 1570 cases registered in the 2 years from July 2006 to June 2008. The hospital mortality rate was low (0.4%) in the follow-up surveys. CONCLUSIONS Early results following the introduction of stent grafts were generally good. The procedure spread safely without the learning curve seen in the initial stages following introduction of new medical materials, indicating that the practice standards were appropriate.

Abstract
AIMS Two different pathways of linoleic acid (LA) metabolism have opposite effects on the development of colonic cancer: a protumoral prostaglandin cascade metabolized by cyclooxygenase (COX)-2, and an antitumoral peroxisome proliferator-activated receptor (PPAR)-gamma ligands metabolized by 15-lipooxygenase (LOX)-1. The aim was to examine the switching of the two LA metabolic pathways in colonic adenomas and carcinomas. MATERIALS AND METHODS The expression of 15LOX-1 mRNA and COX-2 protein was examined in 54 adenomas, 21 pTis carcinoma-in-adenoma lesions and 36 pT3/p Stage II carcinomas of the colon by in-situ hybridization and immunohistochemistry, respectively. RESULTS 15LOX-1 expression was found in 89% (48 of 54) of adenomas, 43% (nine of 21) of adenomas and 10% (two of 21) of carcinomas in carcinoma-in-adenoma lesions, but not in pT3 carcinomas (P < 0.0001). In contrast, COX-2 production was found in 11% (six of 54) of adenomas, 52% (11 of 21) of adenomas and 71% (15 of 21) of carcinomas in carcinoma-in-adenoma lesions, and 92% (33 of 36) of pT3 carcinomas (P < 0.0001). Concurrence of 15LOX-1 down-regulation and COX-2 up-regulation was found in 6% (three of 54) of adenomas, 33% (seven of 21) of adenomas and 71% (15 of 21) of carcinomas in carcinoma-in-adenoma lesions, and 92% (33 of 36) of pT3 carcinomas (P < 0.0001). CONCLUSIONS These results suggest that switching of LA metabolism by reversal of the expression of 15LOX-1 and COX-2 is associated with acquisition of malignant potential in colonic neoplasia.

Abstract
OBJECTIVE To explore the association of promoter polymorphisms of macrophage migration inhibitory factor (MIF) gene with obesity. SUBJECTS In total, 213 nondiabetic Japanese subjects. They were divided into three groups according to World Health Organization definitions: lean (body mass index (BMI) <25 kg/m2), overweight (25 < or = BMI < 30 kg/m2) and obese (BMI> or = 30 kg/m2). METHODS We examined two polymorphic loci in the MIF gene in the subjects: a single-nucleotide polymorphism at position -173 (G/C) and a CATT-tetranucleotide repeat polymorphism at position -794, which both can affect promoter activity in different cells. RESULTS We detected four alleles: 5-, 6-, 7- and 8-CATT at position -794. Genotypes without the 5-CATT allele (X/X, X refers to 6-, 7- or 8-CATT alleles) were more common in obese subjects than in lean or overweight groups (P = 0.013). The X-CATT allele was more frequent in obese subjects than in lean or overweight subjects (P = 0.030). In contrast, -173G/C was not associated with obesity. Among the haplotypes of the two promoter polymorphisms, G/5-CATT ((-173G/C)/(-794[CATT](5-8))) was associated with a decreased risk of obesity (P = 0.025) and G/6-CATT with an increased risk of overweight (P=0.028). CONCLUSION Promoter polymorphism in the MIF gene is linked with obesity.

Abstract
AIM The effectiveness of low-density lipoprotein (LDL) apheresis for patients with peripheral arterial disease (PAD) was investigated to confirm a hypothesis based on subjective evidence that the amelioration of blood rheology would be the most contributing factor for improvement in clinical symptoms. Evaluation of the severity of intermittent claudication is difficult because of the lack of an accurate parameter to assess muscle ischemia during exercise, thus we objectively evaluated by non-invasive near-infrared spectroscopy (NIRS) on a treadmill in this study. METHODS Thirty-one patients with PAD were evaluated for hemostatic function and physiological parameters such as ankle-brachial pressure index (ABI), maximum tolerated walking distance (MTWD) and recovery time (RT) or recovery ability index (RAI) on NIRS. Laboratory tests included plasma assays of total cholesterol, LDL-cholesterol, high-density lipoprotein (HDL) cholesterol, triglyceride, and fibrinogen. The change in red-cell filtration rate was evaluated for the improvement of microcirculation. Statistical analysis was performed using the paired Student's t-test with Bonferroni's correction. RESULTS A significant improvement in ABI and MTWD was observed after average 9.6+/-0.8 sessions of LDL apheresis treatment and the amelioration of microcirculation in ischemic muscle was objectively evaluated as significant improvement in RAI on NIRS. Rest pain was improved in all 5 patients with Fontaine's classification III or IV. A severe ulcer refractory to usual medications was dramatically diminished in the area by 10 sessions of LDL apheresis and fully healed 5 months after the final LDL apheresis treatment followed by medication. No angiographical change was observed in the arterial occlusive lesions in any patients. CONCLUSIONS The effectiveness of LDL apheresis on the improvement in physiological parameters such as ABI, MTWD and clinical symptoms in patients with PAD was confirmed. The severity of intermittent claudication was objectively evaluated using non-invasive NIRS. The RT or RAI was useful parameter to evaluate the improvement in the ischemic symptoms of the extremities.

Abstract
Despite advances in operative technique and management having improved the clinical outcomes of conventional open surgical replacement for thoracic aortic aneurysms, it remains an invasive procedure especially for aged patients. Over the past 10 years, minimally invasive endovascular surgery using a stent graft, has made significant advances for the treatment of aneurysms. For 10 years from 1995, 476 patients of thoracic aortic aneurysms were treated with the endovascular technique using the stent graft in our hospital. Exclusion of the aneurysms without endoleak were achieved within 2 weeks postoperatively in over 95%. Also in elderly patients (46/476), same good results came out. Endovascular stent grafting shows potential as a safe and useful treatment for thoracic aortic aneurysms, but further investigation should attempt to determine its efficacy over a longer postoperative period.

Abstract
Autologous fibrin sealant (AFS) which is not based on the conventional method of co-administering fibrinogen, thrombin and aprotinin was prepared by Vivostat system, and was used in coronary artery bypass grafting (CABG). The purpose of this study was to investigate the safety and efficacy of the AFS prepared by the Vivostat system. In 6 of 68 cases of CABG, normal AFS was not prepared due to device failures. AFS was prepared and sprayed in 62 cases. There were the total of 230 anastomosis sprayed AFS and the bleeding could not seen in 225 anastomosis. Surgical hemostatic procedures (4 cases) were or other sealant usage (1 case) was performed 5 bleeding anastomosis sites. The rate of hemostasis at the anastomosis using AFS was 97.8%. This study was conducted in patients undergoing CABG. In this group of patients, a number of commercial available fibrin sealant products are routinely used. The usefulness of Vivostat as medical device to prepare and administer AFS was confirmed in this study.

Abstract
Between October 1996 and June 2003, endovascular stent graft repair was performed in 87 patients with descending thoracic aortic aneurysms, graft replacement was performed in 24 patients with thoracoabdominal aortic aneurysms, and endovascular stent graft repair with concomitant surgical bypass of abdominal visceral arteries was performed in 3 patients with thoracoabdominal aortic aneurysms. The retrievable stent graft was inserted and evoked spinal cord potential were monitored in order to predict spinal cord ischemia for stent graft repair. There was no paraplegia or hospital death, although 3 patients had paraparesis in stent graft repair. Two of the 3 patients with paraparesis made a full neurologic recovery. There were no cases of paraplegia or paraparesis in surgical operations with thoracoabdominal aortic aneurysm. The concomitant surgical procedure was a good technique for patients in whom cardiopulmonary bypass could not be used. Our results of stent graft repair and surgical operation for descending thoracic or thoracoabdominal aortic aneurysms were acceptable. The retrievable stent graft was useful for prediction of spinal cord ischemia before endovascular stent graft repair of descending thoracic or thoracoabdominal aortic aneurysm.

Abstract
AIM The prevalence of asymptomatic coronary artery stenosis in relation to carotid artery stenosis is influenced by the underlying disease and has yet to be clarified. METHODS A total of 124 consecutive Japanese patients with aortic aneurysm, but without symptoms of coronary artery stenosis, were divided into 2 groups on the basis of carotid ultrasonography: the carotid stenosis group (>or=50% luminal diameter narrowing) and the non-stenosis group. Myocardial imaging was performed using thalium-201 chloride and adenosine triphosphate disodium. RESULTS The mean age and incidence of both cerebrovascular disease and peripheral artery disease were significantly higher in the stenosis group (n=24) than the non-stenosis group (n=100). Defining both fixed and reversible hypoperfusion as positive on the basis of myocardial imaging, a significantly higher number of positive findings were found in the stenosis group (15/24; 62.5%) than in the non-stenosis group (32/100, 32.0%), (Odds ratio: 3.54; p<0.01). The distributions of hypoperfusion defects in the stenosis group were similar to those in the non-stenosis group, but fixed hypoperfusion was more frequently seen in the stenosis group. CONCLUSION The high prevalence of positive findings in the stenosis group indicates that carotid artery stenosis is frequently associated with coronary artery stenosis even in asymptomatic patients, and could be an indicator for advanced atherosclerosis of the coronary artery. The results confirm that stress myocardial imaging is invaluable in the detection of coronary artery stenosis, particularly in patients with carotid arteriosclerosis.

Abstract
A 78-year-old man had a descending thoracic aortic aneurysm with left main coronary artery disease. Combined beating heart coronary artery bypass and endovascular thoracic aortic aneurysm repair was performed without cardiopulmonary bypass. The left anterior descending artery and the obtuse marginal branch of the left circumflex artery were revascularized through a left antero-lateral small thoracotomy. The aneurysm was excluded with stent grafts through a small femoral incision. This combined less invasive procedure is a promising approach providing better surgical results in patients with thoracic aortic aneurysm and severe coronary artery disease.

Abstract
A 67-year-old male was diagnosed to have a right atrial tumor by echocardiography incidentally. Computed tomography (CT) indicated a mass which showed very low radiodensity and magnetic resonance imaging (MRI) [T1-weighted] showed the high signal intensity of tumor. We could predict the mass as lipoma. Tumor removal was performed under cardio-pulmonary bypass and under ventricular fibrillation because of the calcification in ascending aorta. Microscopically the tumor was consisted of mature adipose tissue. The postoperative course was uneventful. Cardiac lipomas are rare tumors. CT and MRI are better investigations for preoperative diagnosis. After surgical excision the prognosis is excellent.

Abstract
We experienced 4 cases of coronary artery-pulmonary artery fistula with coronary aneurysm, three patients had symptoms of chest pain, and 1 patient had cardiac murmur. Coronary arteriography showed that three patients had fistulas from the left coronary artery to the pulmonary artery; and that 1 patient had a fistula from both the right and left coronary arteries to the pulmonary artery. Moreover, 1 patient had 90% diameter stenosis of segment 7. The maximum diameter of the coronary aneurysm ranged from 12 to 20 mm (average: 15.3 mm). One patient underwent closure of the opening of the fistula, 2 patients underwent multiple ligatures of fistulas, and 1 patient underwent multiple ligatures of fistulas with coronary artery bypass grafting. The postoperative course of every patient was uneventful. There have been 42 reports on this abnormality in Japan. We should treat the fistula as early as possible to prevent cardiac complications such as myocardial ischemia and rupture of coronary aneurysm.

Abstract
Paxillin is a protein containing four LIM domains, and functions in integrin signaling. We report here that two transcripts are generated from the paxillin gene locus in Drosophila; one encodes a protein homolog of the vertebrate Paxillin (DPxn37), and the other a protein with only three LIM domains, partly encoded by its own specific exon (PDLP). At the myotendinous junctions of Drosophila embryos where integrins play important roles, both DPxn37 and PDLP are highly expressed with different patterns; DPxn37 is predominantly concentrated at the center of the junctions, whereas PDLP is highly enriched at neighboring sides of the junction centers, primarily expressed in the mesodermal myotubes. Northern blot analysis revealed that DPxn37 is ubiquitously expressed throughout the life cycle, whereas PDLP expression exhibits a biphasic pattern during development, largely concomitant with muscle generation and remodeling. Our results collectively reveal that a unique system exists in Drosophila for the generation of a novel type of LIM-only protein, highly expressed in the embryonic musculature, largely utilizing the Paxillin LIM domains.

Abstract
BACKGROUND AND OBJECTIVE Intimal hyperplasia (IH) leading to restenosis is a major complication of arterial revascularization. The purpose of this study was to investigate the effect of photodynamic therapy (PDT) using mono-L-aspartyl chlorin e6 (NPe6) as a photosensitizer and intraluminal radial irradiation for inhibition of IH experimentally. STUDY DESIGN/MATERIALS AND METHODS Study of laser transmission through the blood indicated that exclusion of blood is a prerequisite for intraluminal PDT. For homogeneous radial laser irradiation to the vessel wall, we used a newly developed cylindrical diffusing balloon laser fiber. Injuries were induced by pulling a balloon catheter through the right iliac artery of rabbits. One and 6 hours after the NPe6 injection (5mg/kg i.v.), drug distribution was examined by fluorescence microscopy. Nineteen rabbits received NPe6 at the time of injuries and PDT was performed with 664-nm laser at 30 and 10 J/cm(2) (20, 30, 40 mW/cm(2)) 1 hour after the injuries. The arteries were harvested at 2 days. In a second group of rabbits, PDT was given at 30 mW/cm(2) (30 J/cm(2)). Two weeks after treatment, the arteries were removed and examined histologically. RESULTS NPe6 was found to be distributed selectively in the injured media. Endovascular NPe6-PDT showed complete depletion of smooth muscle cells even with 10 J/cm(2) at 2 days. IH was significantly inhibited at 14 days after PDT. CONCLUSIONS Endovascular PDT of injured artery using NPe6 can prevent IH in this model of arterial wall injury and may become clinically useful for the prophylaxis of IH.

Abstract
A 64-year-old woman was admitted to our hospital with acute myocardial infarction. She underwent emergent percutaneous transluminal coronary angioplasty. Transthoracic echocardiography revealed mild pericardial effusion on the third day. Pericarditis or cardiac rupture were suspected, so transthoracic echocardiography was repeated serially. On the sixth day, transthoracic echocardiography showed increasing pericardial effusion and abrupt interruption of the apical myocardium of the left ventricle and intact epicardial imaging with systolic expansion. The diagnosis was oozing type cardiac rupture of a subepicardial aneurysm. Surgical treatment was successful and the accuracy of the echocardiographic diagnosis was established.

Abstract
Recent studies suggest that early tracheal extubation after coronary artery bypass grafting (CABG) may reduce intensive care unit use and cost. During recent two years, 96 patients were underwent CABG under cardiopulmonary bypass by low-dose fentanyl and isoflurane anesthesia. We compared two groups of patients for evaluation of factors associated to early tracheal extubation. 47 cases (Group A) were extubated within six hours (average 4.4 hrs) following operation, and 26 cases (Group B) were extubated later than twelve hours (average 57.5 hrs). It is suggested that emergency cases, female, elderly patients, dysfunction of kidney and long operation time associated to late extubation. But early extubation after CABG does not increase perioperative morbidity except for the cases that fell in low cardiac output syndrome or postoperative respiratory complications.

Abstract
From June 1996 to June 2000, 477 endoscopic thoracic sympathectomies (ETS) were performed in 242 patients with palmar hyperhidrosis. Among these, 190 patients were studied who received bilateral sympathectomy (T 2-T 3 ganglionectomy) and were followed for over six months. There were 114 females and 76 males with a mean age of 26 years. Palmar hyperhidrosis was found in all patients and axillary hyperhidrosis in 138 (73%) and plantar hyperhidrosis in 186 (98%) preoperatively. The degrees of palmar, axillary and plantar perspiration were checked immediately (1-2 weeks, 190 patients), as well as in the early (1 year, 190 patients) and late (2-4 years, 65 patients) postoperative periods. In all patients, the hands became dry or normal condition immediately after the operation, and this continued to late period. Disappearance or decrease of axillary sweating was found in 128 patients (93%) in the immediate period and 107 patients (78%) in the early period. Disappearance or decrease of plantar sweating was found in 134 patients (72%) in the immediate period and 115 patients (62%) in the early period. Among 65 patients examined in the late period, axillary hyperhidrosis was found in 24 (37%), and plantar hyperhidrosis was found in 52 (80%). Compensatory sweating was found in 80 patients (42%) in the immediate period and 137 patients (72%) in the early period. In the late period, compensatory sweating developed in 56 patients (86%). In the immediate period, 175 patients (92%) were satisfied with the results of the operation, but this decreased to 83% and 72% at early and late period. However ETS was remarkably effective for palmar or axillary hyperhidrosis and relatively effective for plantar hyperhidrosis, but development of compensatory sweating did occur in some cases.

Endothelin (ET)-1, a potent vasoconstrictor peptide derived from the endothelium, is markedly increased in endotoxic shock, although the pathophysiological role of ET-1 under septic conditions remains obscure. To delineate the role of ET-1 and its receptor subtype in endotoxic shock, we here attempted to determine the changes of circulating levels of ET-1 and its biosynthetic intermediate big ET-1 in endotoxic shock rats, to evaluate the gene expression of ET-1 as well as the ET-1 receptor subtypes (ETA and ETB) in the heart, lung and liver, and to study the effects of ET receptor antagonists on systemic arterial blood pressure, heart rate and survival rate. Administration of bacterial lipopolysaccharide (LPS) caused profound hypotension, increased heart rate and death, and these effects were blocked by a nonselective ETA/ETB receptor antagonist (TAK044), but not by an ETA selective antagonist (BQ123). Administration of exogenous ET-1 caused a profound pressor response in control rats, but not in the LPS-pretreated rats. Injection of LPS caused marked elevation of plasma levels of both ET-1 and big ET-1, which were not affected by treatment with either ET receptor antagonist. Administration of LPS caused up-regulation of ET-1 and ETB receptor mRNA in the heart, whereas ETA receptor mRNA was markedly down-regulated in the heart, lung and liver. These data suggest differential gene regulation of ET-1 and its receptor subtypes in various organs from endotoxic shock rats, and that nonselective ETA/ETB receptor antagonist, but not ETA receptor antagonist, ameliorates endotoxin-induced hypotension and death.

Abstract
OBJECTIVE Recent advances of endovascular stent-grafting (ESG) provide a new therapeutic option with minimum surgical damage for blunt aortic injury (BAI) during its acute phase. To clarify the effectiveness of ESG for BAI, a prospective clinical study at a university hospital was conducted. METHODS All patients with blunt thoracic injury underwent thoracic contrast-enhanced computed tomographic (CT) scan. Six patients age 48.8 +/- 19.8 years, with Injury Severity Scores of 35.8 +/- 8.1, and with BAI were treated according to our protocol. The stent-graft covered by woven Dacron was placed at the injury site. Endoleakage was then checked by aortography and CT scan was again performed once a day on days 7 through 14. RESULTS All patients had injury of the aortic isthmus. ESG placement was performed within 8 hours after injury except in one (48 hours). The operating time was 159.5 +/- 21.1 minutes and bleeding volume was 105 +/- 26.6 mL. No endoleakage was found. Repeat CT scan revealed disappearance of hematoma. All patients except one had an event-free clinical course. One patient died because of rupture of the ascending aorta on day 6; however, autopsy revealed evidence of the healing process at the injury site sealed by ESG. CONCLUSION An ESG is a valid therapeutic option with minimal surgical invasion for patients with acute-phase aortic injury.

Abstract
OBJECTIVES To assess the effects of competitive blood flow on internal thoracic artery grafts, we investigated postoperative flow velocity characteristics and angiographic findings of the grafts with various grades of native coronary artery stenosis. METHODS Fifty patients who had an internal thoracic artery graft to the left anterior descending artery underwent intravascular Doppler graft velocimetry during postoperative angiography. Patients were divided into 3 groups according to the grade of native coronary stenosis: group H (28 patients), 80% stenosis or greater; group M (16 patients), 60% to 79% stenosis; and group L (6 patients), 40% to 59% stenosis. Phasic flow velocity of the grafts was measured with an intravascular Doppler ultrasound-tipped guide wire during angiography. Graft flow volume was calculated from the diameter and the average peak velocity. RESULTS Average peak velocity (group H, 27.1 +/- 8.6 cm/s; group M, 16.9 +/- 3.9 cm/s; group L, 7.2 +/- 3.7 cm/s), distal graft diameter (group H, 2.27 +/- 0.23 mm; group M, 2. 00 +/- 0.28 mm; group L, 1.07 +/- 0.27 mm), and calculated graft flow volume (group H, 33.1 +/- 12.0 mL/min; group M, 16.2 +/- 5.8 mL/min; group L, 2.3 +/- 2.0 mL/min) significantly differed among the 3 groups. Graft flow in diastole and systole also differed among the 3 groups. CONCLUSIONS Competitive blood flow reduces internal thoracic artery graft flow and diameter according to the grade of the native coronary artery stenosis. These data suggest that grafting the internal thoracic artery to the coronary artery with stenosis of a low grade can cause graft atrophy and failure.

Abstract
We present here a case of pyoderma gangrenosum (PG) on the stump of an amputated leg. The patient was a 69-year-old woman who had both of her legs amputated due to acute arterial occlusion. An ulcer first appeared nine years later, after which point it continued to fluctuate in size. Complications included regional blood flow disorder at the amputated stump, diabetes, and secondary infection. Despite various therapies, the ulcer exacerbated, and hypoproteinemia, increased CRP, and fever were confirmed. The patient was diagnosed as having PG based on her clinical symptoms and because the ulcer did not respond to various therapies. The ulcer improved significantly in response to administration of 40 mg/day of prednisolone, and complete epithelialization was later achieved. Given the presence of multiple complications, it was extremely difficult to confirm PG. Therefore, it is important for physicians to consider PG as one of the causes of intractable ulcers.

Abstract
A recent development in antithrombotic research allows the inhibition of platelet aggregation via protection of the glycoprotein IIb/IIIa receptor on the platelet membrane. We hypothesized that a GP IIb/IIIa receptor inhibitor would inhibit thromboxane-induced platelet aggregation during circulation in our in vitro ventricular assist device (VAD) circuit and preserve long-term platelet function. Twenty-one in vitro nonpulsatile centrifugal VAD circuits were simulated for 4 days using 450 ml of fresh human whole blood with or without glycoprotein IIb/IIIa receptor inhibitor (tirofiban). Platelet aggregation and degranulation were measured in whole blood induced by ristocetin, collagen, ADP, and thromboxane A2 (TXA2). The tirofiban-treated group preserved the platelet count and tended to exert these beneficial effects by inhibiting pathologic platelet aggregation induced by TXA2, collagen, and ADP as well as degranulation. Tirofiban may be useful in preserving platelet number and function during clinical VAD use.

Abstract
A 60-year-old female presented with occipital headache and limitation of neck movement. Neurological examination showed weakness of the right sternocleidomastoid muscle. Magnetic resonance imaging revealed a cystic lesion at the craniocervical junction and posterior compression of the brain stem. The lesion was totally removed through the transcondylar approach. The histological diagnosis was neurenteric cyst. The transcondylar approach provides a direct operative view of the clivus and anterior craniovertebral junction.

Abstract
Endovascular stent grafting for aortic aneurysms using metallic stents covered with conventional vascular grafts has attracted attention as a catheter-based, minimally invasive alternative to open surgery. Since the first clinical experience with endovascular stent grafting for an abdominal aortic aneurysm was reported in 1991, experimental and clinical investigations have between undertaken world wide. Although several commercial bifurcated stent grafts for abdominal aortic aneurysms are currently available in Europe and Australia, none of the devices are approved for clinical use in Japan and the USA. Hand-made devices are still used in each institution particularly for thoracic aortic aneurysms. Endovascular stent grafting is feasible for aneurysm repair within limited conditions. However, several unsolved issues remain concerning not only delivery devices which require precise skill in stent-graft deployment, but also concerning patient selection and proper indications. Further investigation is necessary to clarify graft durability, aneurysmal neck enlargement, and the fate of the excluded aneurysm sac for long follow-up periods.

Abstract
A 60-year-old man suffered antero-septal myocardial infarction at the age of 56. Coronary angiography demonstrated total occlusion of the left anterior descending artery and a large saccular aneurysm of the right coronary artery. Diffuse coronary ectasia was also shown in the right coronary artery adjacent to the aneurysm. Despite anticoagulant therapy, the aneurysm formed a thrombus and developed coronary artery stenosis distal to the aneurysm. Ligation of the aneurysm and in situ gastroepiploic artery grafting were performed. Sudden heart failure was developed during skin closure. As this condition was considered to be graft hypoperfusion, supplemental saphenous vein grafting was placed. Ligation is a simple, reliable technique to prevent future complications for a large saccular right coronary artery aneurysm, however, gastroepiploic artery might be an inappropriate bypass conduit for the ligated coronary artery with diffuse ectasia.

Abstract
A 62-year-old man with left main coronary artery disease had coronary artery bypass grafting. Angiography disclosed total occlusion of the left common iliac artery. The left internal thoracic artery and the left inferior epigastric artery were well developed as collateral pathways to the left external iliac artery. With concomitant femoro-femoral crossover bypass, these two large arterial conduits were harvested and grafted to the coronary artery.

Abstract
Cas ligand with multiple Src homology (SH) 3 domains (CMS) is an ubiquitously expressed signal transduction molecule that interacts with the focal adhesion protein p130(Cas). CMS contains three SH3 in its NH2 terminus and proline-rich sequences in its center region. The latter sequences mediate the binding to the SH3 domains of p130(Cas), Src-family kinases, p85 subunit of phosphatidylinositol 3-kinase, and Grb2. The COOH-terminal region contains putative actin binding sites and a coiled-coil domain that mediates homodimerization of CMS. CMS is a cytoplasmic protein that colocalizes with F-actin and p130(Cas) to membrane ruffles and leading edges of cells. Ectopic expression of CMS in COS-7 cells resulted in alteration in arrangement of the actin cytoskeleton. We observed a diffuse distribution of actin in small dots and less actin fiber formation. Altogether, these features suggest that CMS functions as a scaffolding molecule with a specialized role in regulation of the actin cytoskeleton.

Abstract
An aortogastric fistula is a rare but fatal complication after an esophagectomy and intrathoracic esophagogastric anastomosis. A 54-year-old man underwent an esophageal resection due to carcinoma in his lower esophagus. The alimentary tract continuity was restored by intrathoracic esophagogastric anastomosis. Forty-six days later, he suffered a massive hematemesis due to an aortogastric fistula which had formed at the esophagogastric suture line. The fistula was surgically obliterated twice, but each operation was followed by pseudoaneurysm formation. The patient was finally successfully treated with an endovascular stent graft placement. This is the first report of a patient surviving after developing this complication.

Abstract
Two patients who had aortopulmonary fistula of postoperative origin with hemoptysis underwent successful repair by means of an endovascular stent graft procedure. One patient had undergone repeated thoracotomies two times, and the other one time to repair anastomotic aneurysms of the descending aorta after surgery for Takayasu's arteritis. A self-expanding stainless steel stent covered with a Dacron graft was inserted into the lesion through the external iliac or femoral artery. The patients recovered well, with no signs of infection or recurrent hemoptysis 8 months after the procedure. Endovascular stent grafting may be a therapeutic option for treating patients with aortopulmonary fistula.

Abstract
A questionnaire survey was performed in order to investigate the current status of endoscopic thoracic sympathectomy in Japan. Four hundred and twenty-nine (429) university, national or public hospitals with a minimum of 400 beds were included. A total of 248 of these hospitals responded. Among them 63 (25%) performed this procedure. The total of the cases was 1116. The number of access port and the technique for defunctioning the sympathetic chain were broadly divided into three methods. These methods were equally carried out among the departments. The clinical results were judged as satisfactory in the great majority of patients and the frequency of complications was low. On the other hand, the overall incidence of compensatory sweating remained relatively high and accumulated as the number of cases increased. But the reported frequency differed strikingly from hospital probably for lack of an objective way of quantifying following sympathectomy. Although overall complications were infrequent, the need for conventional thoracotomy to stop bleeding occurred in some cases. Therefore even this simple endoscopic operation demands the utmost surgical care, skill and experience. A few recurrences of preoperative symptoms were seen in the follow-up suggesting that all patients must be continually monitored after the operation.

Abstract
Downward transtentorial herniation is a major cause of death and disability caused by acute supratentorial mass lesions. Thirteen patients, 7 men and 6 women aged from 23 to 75 years old, with progressive transtentorial herniation caused by cerebral contusion with acute subdural haematoma, acute brain swelling after aneurysmal subarachnoid haemorrhage, or massive cerebral infarction were treated by direct surgery using selective removal of the uncus and parahippocampal gyrus (unco-parahippocampectomy). All patients showed progressive deterioration of transtentorial herniation (late third nerve stage or midbrain stage) with unilateral pupillary dilation and absent light reflex. Preoperative Glasgow Coma Scale scores ranged from 4 to 8. Unco-parahippocampectomy was performed via the middle temporal gyrus under the operating microscope. The oculomotor nerve, posterior cerebral artery, and midbrain were directly decompressed. Incision of the arachnoid membrane in the tentorial incisura allowed free communication of the cerebrospinal fluid between the supra- and finfra-cranial fossae to reduce the pressure gradient. Two of the 13 patients died (15%). Two of the 11 survivors (18%) were functionally independent and 1 (9%) required minimal assistance but was independent at home. This series suggests the lifesaving nature of unco-parahippocampectomy in patients with deteriorating clinical condition because of transtentorial herniation.

Abstract
The cellular signal transduction pathways by which C3G, a RAS family guanine nucleotide exchange factor, mediates v-crk transformation are not well understood. Here we report the identification of Drosophila C3G, which, like its human cognate, specifically binds to CRK but not DRK/GRB2 adaptor molecules. During Drosophila development, constitutive membrane binding of C3G, which also occurs during v-crk transformation, results in cell fate changes and overproliferation, mimicking overactivity of the RAS-MAPK pathway. The effects of C3G overactivity can be suppressed by reducing the gene dose of components of the RAS-MAPK pathway and of RAP1. These findings provide the first in vivo evidence that membrane localization of C3G can trigger activation of RAP1 and RAS resulting in the activation of MAPK, one of the hallmarks of v-crk transformation previously thought to be mediated through activation of SOS.

Abstract
BACKGROUND Photosensitizers, such as Photofrin II or Chloroaluminum-sulfonated phthalocyanine accumulate at sites of arterial injury. We have exploited this property to develop a model of photodynamic therapy (PDT) for intimal hyperplasia. The fluorescent probe [maleylated-bovine serum albumin (mal-BSA) conjugated with Texas-red] can be selectively targeted to intimal macrophages and smooth muscle cells recruited during formation of hyperplasia via a receptor-mediated mechanism. METHODS In this study, the photosensitizer chlorin e6 (Cle6) was conjugated to mal-BSA in a rat model of intimal hyperplasia, then tested the efficacy of the ligand conjugation to photosensitizer (mal-BSA/Cle6) in PDT of intimal hyperplasia. Arterial wall injury was produced by a balloon catheter pulled through the abdominal aorta of the rat to create a model of intimal hyperplasia. Fluorescent compounds were injected two weeks after injury. RESULTS Four hours after injection, the intensity of fluorescence achieved with injection of mal-BSA/Cle6 was higher for intimal hyperplastic lesions as compared to control areas. BSA-Cle6 unconjugated did not demonstrate such delivery. Two weeks after balloon injury, the injured aorta was irradiated externally with an argon pumped dye laser four hours following the photosensitizer injection. We employed two total radiant exposures: 20 J/cm2 and 40 J/cm2. Forty-eight hours after PDT, the arteries were examined histologically. Intimal hyperplastic cells were significantly reduced by PDT in the mal-BSA/Cle6 injected group (40-100%) versus the Cle6 group (0-20%). CONCLUSIONS Mal-BSA/Cle6 is taken up efficiently by a scavenger pathway, localizes in areas of intimal hyperplasia, and functions as a photosensitizer for PDT.

Abstract
Dynamic biologic modeling was used to calculate the transfer rate constant for gadolinium-diethylenetriaminepenta-acetic acid (Gd-DTPA) and capillary permeability in the outer membrane of chronic subdural hematomas and effusions. Following intravenous Gd-DTPA injection, Gd concentrations in the subdural fluid and in timed arterial blood samples were measured by ion-coupled plasma emission spectrometry in 53 chronic subdural hematomas and 18 chronic subdural effusions. The capillary surface area in outer membrane was assessed morphometrically. Transfer rate constants for subdural hematomas and subdural effusions were 12.4 +/- 1.0 and 20.6 +/- 1.7 (x 10(-4)min-1, respectively. Capillary permeabilities for subdural hematomas and subdural effusions were 16 +/- 1.2 and 19 +/- 3.7 ml.min-1(mm2/mm3)-1, respectively. The capillary surface areas for subdural hematomas and subdural effusions were 48 +/- 3 and 77 +/- 10 mm2/mm3, respectively. The high degree of infiltration of Gd into subdural effusions reflects the high capillary surface area in the outer membrane rather than greater permeability of individual capillaries. The value of transfer rate constant was correlated inversely with the duration of the chronic subdural fluid collection. Immature outer membrane has a high transfer rate constant which allows extravasation of plasma components into the subdural space, resulting in increasing volume of the subdural effusion. Delayed magnetic resonance imaging following Gd administration may be clinically useful for estimating the age of chronic subdural fluid accumulations.

Abstract
Between February 1995 and December 1997, 50 cases (55 lesions) of thoracic aortic aneurysms including 20 cases of aortic dissections were treated with an endovascular technique using the stent grafts. All patients were treated in the operating room under general anesthesia and the stent grafts were implanted through 18 Fr. or 20 Fr. sheaths via femoral arteries under fluoroscopic guidance. The stent graft was composed of several units of self-expanding stainless-steel Z stents covered with an ultra-thin polyester fabric. Stent graft deployment was technically successful in 53 of 55 lesions (delivery success rate: 96.4%). Exclusion of the aneurysms and entry closing without endoleak were achieved within two weeks after the operation in 43 of 53 lesions (initial success rate: 81.1%). Endoleak was found in 10 lesions (minor endoleak: 8 and major endoleak: 2 lesions). Two patients died in the periopertive period of delivery failures as injury to external iliac artery and damage to the delivery sheath caused by tortuous and narrow access routes. Endovascular stent graft repair of thoracic aortic aneurysms is minimally invasive operation in comparison with conventional surgical graft replacement with extracorporeal circulation. These early results suggest that the stent graft repair is possibly safe and useful treatment for the patients of thoracic aortic aneurysms especially in high risk patients. However, careful long-term follow-up is necessary to prove the value and the effects of this endovascular treatment and improvement of the stent graft system and technical training of endovascular surgery for operators are required to reduce the delivery failure and to determine the stent graft repair is reliable treatment.

Abstract
Multiple aortic aneurysms in Behçet's disease were repaired with transluminaly placed endovascular stent grafts. Before deploying the stent graft device for permanent implantation for the saccular aneurysm located in the descending thoracic aorta, from which feeding arteries for the spinal cord possibly branched, a retrievable stent graft was inserted and evoked spinal cord potential (ESP) were monitored in order to predict spinal cord ischemia. The original retrievable stent graft, constructed of a self-expandable Z-shaped stainless steel stent covered with e-PTFE, can be easily withdrawn into a 18 Fr. sheath after deployment. Blood flow into intercostal arteries branching from that part of the descending aorta where the permanent stent graft is planned to be implanted, is intercepted by the retrievable stent graft. A change of ESP during the temporary implantation of the device indicates that spinal cord ischemia would be caused by permanent implantation of the stent graft. In this case, no change of ESP was observed and the patient showed no postoperative paraplegia. The retrievable stent graft was useful for prediction of spinal cord ischemia before endoluminal stent graft repair of the descending aortic aneurysm. However, the device is not flexible enough to fit a severely tortuous aorta, therefore we are obliged to select patients to some extent. Further improvement of the device is required to make prediction of spinal cord ischemia with the retrievable stent graft possible in all cases.
