Abstract
While endovenous thermal ablation (ETA) become first choice of treatment for varicose veins, overuse of ETA for the inappropriate indication is growing problem. ETA is performed not only on varicose cases without symptom but also non diseased cases with segmental reflux of saphenous veins or no reflux. Indications of ETA was demonstrated in “the Clinical Practice Guidelines for ETA for Varicose Veins 2019” by Japanese Society of Phlebology. Purpose of this supplement is description of basics of correct indication for ETA. We also demonstrate the typical case of overuse of ETA for wrong indication.

Abstract
Patients with varicose veins of the lower extremities with osteoarthritis of the knee often experience improvement in knee joint symptoms after endovascular treatment. We considered that it was important to decide the operation indication of lower extremity varices, to know the correlation between the two diseases in the treatment of varicose veins. To investigate the postoperative improvement of knee symptoms related to varicose veins with knee osteoarthritis, we conducted a questionnaire survey for a total of 12 months, from December 2014 to May 2015 and from October 2018 to March 2019. The participants were 35 patients (7 men and 28 women) with varicose veins complicated with knee osteoarthritis. We classified knee osteoarthritis according to a grading scale and compared the improvement of knee symptoms after endovenous thermal ablation. The higher the knee grade, the lower the degree of improvement. However, the improvement was observed in all knee osteoarthritis grades, and as a whole, 25 patients (71.4%) have experienced improvement of subjective symptoms. For patients with knee osteoarthritis, we strongly recommend surgical treatment of the varicose veins regardless of the progression of knee grade.

Abstract
Aim We developed and psychometrically tested the Japanese version of the Professional Attitude Scale for Nurses (PASN‐J). Background Nurses must recognize the importance of their professionalism; therefore, it is critical to quantitatively measure nurses’ professional attitudes. Introduction This instrument validation study was designed to generate an itemized scale and examine its content validity/psychometric testing using a sample of Japanese nurses. Methods Based on a trait approach focusing on the characteristic traits of the nursing profession, a 59‐item draft scale was generated. During November 2017, 2657 nurses from 29 facilities in Japan were surveyed. The questionnaire included demographics, the 59‐item draft scale, and a self‐report scale of nurses’ professional behaviour and nursing practice ability. Using exploratory and confirmatory factor analyses, we evaluated the construct, criterion‐related, concurrent, and known‐groups validity, and reliability of the PASN‐J. Results Data from 1716 participants were analysed. The analyses yielded a 38‐item, 3‐factor scale that adequately fit the data. PASN‐J scores were positively correlated with nurses’ professional behaviour and nursing practice ability. Conclusion The 38‐item PASN‐J has good reliability and validity, making it useful for measuring the current condition of nursing professionalism and evaluating nursing education. Implications for Nursing and Health Policy: This scale can evaluate nursing education and promote nurses’ professionalism. The PASN‐J will help identifying the elements of undergraduate nursing education that require further emphasis. Additionally, the PASN‐J could facilitate the development of nursing policies to promote professional development in nurses. Ultimately, evaluating nursing education with the PASN‐J enhances nurses’ professional attitudes and subsequently improves their quality of nursing, nursing efficiency and patient outcomes.

Abstract
BACKGROUND We aimed to elucidate the characteristics and prognosis of autoimmune hepatitis (AIH) patients with immunoglobulin (Ig) G4-positive plasma cell infiltration. METHODS We enrolled 84 AIH patients. The number of IgG- and IgG4-positive plasma cells was immunohistochemically counted per high-power field in the portal area. Patients with 3 or more IgG4-positive plasma cells on average and a ratio of IgG4 to IgG-positive plasma cells ≥5% were defined as IgG4-associated AIH (IgG4-AIH), and their clinicopathological characteristics and prognosis were compared to those of the remaining classical-AIH patients. RESULTS Ten (11.9%) and 74 patients (88.1%) were categorized as IgG4-AIH and classical-AIH patients, respectively. The median age of the IgG4-AIH patients was 67 years, the majority was female (80.0%), and the distribution was similar to that of the classical-AIH patients. The IgG4-AIH patients exhibited significantly more severe phenotypes in portal inflammation, interface hepatitis, fibrosis, and rosette formation. All clinical laboratory data were similar except for serum IgG4 levels, which were higher in IgG4-AIH patients (168.5 vs. 22.9 mg/dL, p = 0.014). During a median follow-up period of 139 months, the relapse rate was significantly lower in the IgG4-AIH group than in the classical-AIH group (11.1 vs. 49.2%; p = 0.048). Twelve (16.2%) and 6 (8.1%) classical-AIH patients underwent liver-related events and liver-related deaths, respectively. In contrast, none of the IgG4-AIH patients progressed to severe liver disease. CONCLUSIONS The IgG4-AIH patients had more severe inflammation and advanced fibrosis in the liver. However, their prognosis was not poor compared to that of classical-AIH patients. IgG4-AIH may have a phenotype distinct from classical-AIH.

Prevention of Thromboembolic Infarction After Surgery for Traumatic Cervical Fracture with Vertebral Artery Occlusion by Preoperative Endovascular Coil Embolization. World Neurosurg 2019; 129:e838-e844.

Abstract
BACKGROUND Vertebral artery injuries (VAIs) caused by cervical trauma include irregularities with narrowing of the arterial wall, dissection, pseudoaneurysm formation, occlusion, and transection. Although recent guidelines have recommended anticoagulant or antiplatelet therapy to prevent subsequent stroke in patients with traumatic VAIs, regardless of the type of vascular injury, the clinical role of endovascular surgery in the treatment of traumatic VAIs remains to be elucidated. METHODS We retrospectively evaluated the treatment outcomes of 23 patients with cervical fracture and vertebral artery occlusion (VAO) who had required cervical surgery in the acute stage. RESULTS No patient received antiplatelet or anticoagulant therapy, because the VAs had already become occluded. After cervical surgery, 5 of the 23 patients developed radiologically confirmed thromboembolic stroke after cervical surgery. None of these 5 patients with postoperative infarction had undergone preoperative VA embolization. Univariate analysis revealed that only the implementation of preoperative VA embolization was associated with the prevention of postoperative infarction (P = 0.004). Factors such as age, reduction, level of VAO, and diabetes mellitus did not correlate with increased risk. CONCLUSIONS The clinical role of endovascular surgery for traumatic VAI has not been previously established; however, a more specific selection of patients according to the VAI type might be necessary. Our data have indicated that preoperative embolization of the occluded VA significantly reduces the risk of postoperative infarction in a specific cohort of patients with traumatic VAI (i.e., patients with post-traumatic VAO who require cervical surgery).

Abstract
Background This in vitro study aimed to clarify the combined effect of electric toothbrushing and dentifrice on the removal of artificial stain. Material and Methods Twenty-five bovine incisors were cut at the cervix and the crown was embedded in auto-cured acrylic resin. Specimens were abraded using #240 SiC paper to obtain a flat enamel surface, and 20 specimens were treated with 10% citric acid / 3% ferric chloride solution followed by 1% tannic acid solution to produce surface staining. They were divided into four groups: 1) brushing with an electric toothbrush and whitening dentifrice (group S+B); 2) brushing with an electric toothbrush and fluoride dentifrice (group S+C); 3) brushing with an electric toothbrush and no dentifrice (group S); and 4) no brushing (control group). The remaining five specimens were used as a baseline. Color values (L*, a*, and b* were measured before brushing (0 min), and at 1 min, 5 min, 10 min, and 20 min using a microscopic area spectrophotometer. The color change (ΔE) was calculated by subtracting the baseline values from the final color values obtained at each time point. The data were statistically analyzed using two-way repeated-measures analysis of variance and Tukey’s honest significant difference test as a post hoc test (p<0.05). Results The L* values of groups S+B and S+C increased over time (p<0.05), but no significant differences were observed in group S and the control group at any of the time points (p>0.05). Groups S+B and S+C demonstrated greater ΔE values than group S. Conclusions The combination of electric toothbrushing and dentifrice removed the artificial stain more effectively than brushing without dentifrice. However, the stain removal was limited. The two dentifrices evaluated in this study exhibited similar stain removal effects. Key words:Color change, stain removal, dentifrice, electric toothbrush, whitening effect.

Abstract
Heavy/light chain (HLC) assay will enable us to evaluate the changes in the concentrations of iHLC and uHLC separately and to better identify whether the change observed is clonal or reactive. It would therefore aid in decision making for earlier implementation or discontinuation of treatment for patients with intact immunoglobulin multiple myeloma (MM).

Abstract
Aim Hemorrhage from pelvic fracture is a major cause of mortality after blunt trauma. Several studies have suggested that early fibrinogen supplementation improves outcomes of traumatic hemorrhage. Thus, we revised our massive transfusion protocol (MTP) in April 2013 to include early off‐label administration of fibrinogen concentrate. The objective of this study was to evaluate the impact of the revision on the short‐term outcomes of pelvic fracture patients. Methods This was a single‐center, retrospective, cohort study. A total of 224 consecutive pelvic fracture patients hospitalized in Saitama Medical Center (Saitama, Japan), 115 before the revision (Group E) and 109 after (Group L), were enrolled. Characteristics of the patients were compared between the groups. Impacts of the revision were evaluated by hazard ratios adjusted for characteristics, injury severity, and coagulation status using Cox's multivariate proportional hazard model. The impact was also evaluated by log–rank test and relative risk of 28‐day mortality between the groups. Results The characteristics were equivalent between the groups. The multivariate analysis revealed that the revision of MTP was significantly related to improved survival with an adjusted hazard ratio (95% confidence interval) of 0.45 (0.07–0.97). The log–rank test gave χ2‐test values of 5.2 (P = 0.022) and 6.7 (P = 0.009), and the relative risks were 0.37 (0.15–0.91) and 0.33 (0.13–0.84), in patients with all Injury Severity Scores and Injury Severity Score ≥21, respectively. Conclusion The revision of MTP to include aggressive off‐label treatment with fibrinogen concentrate was related to improved short‐term outcomes of severe pelvic fracture patients. However, due to the limitations of the study, the improvement could not be attributed totally to the revision.

Abstract
Background Patients with severe trauma often present with critical coagulopathy, resulting in impaired hemostasis, massive hemorrhage, and a poor survival prognosis. The efficacy of hemostatic resuscitation in correcting coagulopathy and restoring tissue perfusion has not been studied. We assessed a novel approach of pre-emptive administration of fibrinogen concentrate to improve critical coagulopathy in patients with severe trauma. Methods We retrospectively compared blood transfusion volumes and survival prognosis between three groups of patients with trauma, with an Injury Severity Score (ISS) ≥26 over three consecutive periods: group A, no administration of fibrinogen concentrate; group B, administration of 3 g of fibrinogen concentrate after evaluation of trauma severity and a plasma fibrinogen level <1.5 g/L; group C, pre-emptive administration of 3 g of fibrinogen concentrate immediately on patient arrival based on prehospital information, including high-severity injury or assessed need for massive transfusion before measurement of fibrinogen. Results ∼56% of patients with an ISS ≥26 and transfused with red blood cell concentrates ≥10 units, had hypofibrinogenemia (fibrinogen <1.5 g/L) on arrival. Patients who received fibrinogen concentrate in group C showed significantly higher fibrinogen levels after treatment with this agent than those in group B (2.41 g/L vs 1.88 g/L; p=0.01). Although no significant difference was observed in blood transfusion volumes between the groups, the 30-day survival of patients in group C (all, and those with an ISS ≥26) was significantly better than in group A (p<0.05). The 48-hour mortality rate in patients with an ISS ≥26 was significantly lower in group C than in group A (8.6% vs 22.9%; p=0.005). Further, among patients with an ISS ≥41, the overall mortality was significantly lower in group C than in group A (20% vs 50%; p=0.02). Conclusion Pre-emptive administration of fibrinogen concentrate for patients with trauma with critical coagulopathy may contribute to improved survival. Level of evidence Level IV.

Abstract
BACKGROUND AND AIMS Fish consumption is a recognized risk factor for elevated serum uric acid (UA) levels, hyperuricemia, and gout. However, the relationship between the consumption of fish cooked by different methods and the risk of hyperuricemia is unclear. Therefore, we aimed to investigate the relationship between the consumption of fish cooked by different methods and the risk of hyperuricemia in Japanese adults. METHODS AND RESULTS A 3-year follow-up study was conducted with 424 Japanese adults aged 29-74 years. Fish consumption was assessed using a validated self-administered dietary history questionnaire, and hyperuricemia was defined as serum UA ≥7 mg/dL in men and ≥6 mg/dL in women or the use of any anti-gout treatment. During the 3-year follow-up period, we documented 30 newly diagnosed cases of hyperuricemia. After adjusting for potential confounders, multivariate logistic regressions analysis revealed a significant positive relationship between the risk of hyperuricemia and raw (sashimi and sushi) or roasted fish consumption, but not boiled or fried fish consumption. The odds ratios (95% CI) for hyperuricemia with increasing raw fish consumption were 1.00 (reference), 2.51 (0.85, 7.39), and 3.46 (1.07, 11.14) (P for trend: 0.036). Similarly, the odds ratios (95% CI) with increasing roasted fish consumption were 1.00 (reference), 3.00 (0.75, 11.89), and 5.17 (1.30, 20.62) (P for trend: 0.018). CONCLUSION This 3-year follow-up study showed that the consumption of raw or roasted fish, but not boiled or fried fish, was related with a higher risk of hyperuricemia in Japanese adults.

Abstract
BACKGROUND Optimal design of stents for a cerebral aneurysm is desired for efficient flow reduction in the aneurysm. OBJECTIVE In this study, we aimed to optimize stent design at several porosities, estimate the influence of stent design on aneurysm flow, and evaluate the ability of stents to reduce flow. METHODS Stent models were constructed as sets of squares or rectangles in the necks of a two-dimensional (2D) and realistic aneurysm. Then, automated optimization was performed using a combination of simulated annealing and lattice Boltzmann flow simulation. RESULTS By simulated annealing, stents were gradually modified to reduce the average velocity in an aneurysm. As a result of optimization, stents of all porosities demonstrated an inhomogeneous distribution with dense struts in the inflow area. Flow reduction was increased compared with the initial stent. Under the condition of high porosity, flow reduction by the stent drastically increased as porosity decreased. Under low porosity, the increase of velocity reduction was moderate even as porosity decreased. CONCLUSIONS Optimization can enhance flow reduction by stents. However, the increase in reduction associated with decreasing porosity is moderate under lower-porosity conditions. This threshold may help in the choice of stent porosity for each specific aneurysm.

[RADIOFREQUENCY ABLATION FOR THE TREATMENT OF VARICOSE VEINS]. NIHON GEKA GAKKAI ZASSHI 2015; 116:161-165. [PMID: 26281655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/04/2023]
Abstract
Significant advances in the endovenous technique for treating incompetent saphenous veins could change the surgical strategy in patients with varicose veins. Radiofrequency ablation (RFA) was approved as a new technique for the treatment of varicose veins in Japan in June 2014. In RFA, the ablation temperature is controlled by a sensor at the upper end of the catheter. The vein wall is heated with stable conductive power of 120 degrees C, resulting in endothelial denudation. The RFA method was approved in 1998 in Europe and in 1999 in the USA. The ClosurePLUS catheter was developed in 2003 and ClosureFAST in 2006. High occlusion rates and lower postoperative complication rates were reported with ClosureFAST than with ClosurePLUS. It is expected that this new ablation technique will control saphenous vein reflux with less pain and less ecchymosis after surgery. The treatment of varicose veins is less invasive with RFA devices and will become widely accepted as an alternative to conventional surgery for varicose veins in Japan.

Abstract
Administering 15N-labelled glycine, 15 N incorporation into serum albumin and its excretion into urine and feces, together with nitrogen balance were investigated in 3 nephrotic and 2 normal adults. Furthermore, 15N-labelled urea was injected into a nephrotic adult and a glomerulonephritic adult, both advanced in azotemia and treated on low protein diet, and a normal subject on a normal diet, to examine the amounts of 15N incorporation into serum albumin. In the 3 nephrotic patients whose nitrogen balance was almost maintained, incorporation of 15N-glycine into serum albumin has been proved greater than in the normal subjects. In any of the above patients, 15N excretion into urine was less than in the normal subjects. Fecal 15N excretion was 2.0--2.5 % of the doses, indicating that approximately 98 % of 15N-glycine was absorbed. In the nephrotic patients, 15N incorporation into serum albumin examined by 15N-labelled urea administration was more accelerated than in the glomerulonephritic patients and was negligible in the control subject on a normal diet.

Abstract
BACKGROUND AND PURPOSE Rupture risk assessment for intracranial aneurysms remains challenging, and risk factors, including wall shear stress, are discussed controversially. The primary purpose of the presented challenge was to determine how consistently aneurysm rupture status and rupture site could be identified on the basis of computational fluid dynamics. MATERIALS AND METHODS Two geometrically similar MCA aneurysms were selected, 1 ruptured, 1 unruptured. Participating computational fluid dynamics groups were blinded as to which case was ruptured. Participants were provided with digitally segmented lumen geometries and, for this phase of the challenge, were free to choose their own flow rates, blood rheologies, and so forth. Participants were asked to report which case had ruptured and the likely site of rupture. In parallel, lumen geometries were provided to a group of neurosurgeons for their predictions of rupture status and site. RESULTS Of 26 participating computational fluid dynamics groups, 21 (81%) correctly identified the ruptured case. Although the known rupture site was associated with low and oscillatory wall shear stress, most groups identified other sites, some of which also experienced low and oscillatory shear. Of the 43 participating neurosurgeons, 39 (91%) identified the ruptured case. None correctly identified the rupture site. CONCLUSIONS Geometric or hemodynamic considerations favor identification of rupture status; however, retrospective identification of the rupture site remains a challenge for both engineers and clinicians. A more precise understanding of the hemodynamic factors involved in aneurysm wall pathology is likely required for computational fluid dynamics to add value to current clinical decision-making regarding rupture risk.

Abstract
Persisting incompetent great saphenous vein (GSV) below the knee and residual incompetent perforating veins (IPV) are often found after selective stripping of GSV from the groin to upper calf. The aim of this study is to evaluate the venous function when the calf GSVs or calf perforating veins are incompetent after stripping surgery. One hundred-thirty-one limbs were treated by stripping from the groin to upper calf with stab avulsion or sclerotherapy of varices. One month and twelve months after surgery, the patients were examined clinically to establish the extent of persisting varices by duplex ultrasonography and air-plethysmography. Venous filling index (VFI) was a little higher in those who had residual calf GSV reflux 12 months later; it was also higher in the group with incompetent perforating veins than the group without. The chief complaints were found to have improved in all groups. The findings suggest that removal of the saphenous vein below the knee is not necessary, but it is important to take care of the incompetent perforating veins.

Abstract
BACKGROUND The serum Krebs von der Lungen-6 (KL-6) level is a useful marker correlated with the severity of various interstitial lung diseases. There have been few reports about the clinical characteristics of organizing pneumonia (OP) associated with the serum KL-6 levels. OBJECTIVE This study was performed to determine whether the serum KL-6 levels can help determine the optimal treatment for OP. DESIGNS Patients diagnosed with OP by clinical, radiological and histopathological findings were retrospectively reviewed. The OP patients were classified into two groups based on their serum KL-6 levels: normal KL-6 and high KL-6 groups. The two groups were compared with regard to their clinical and radiological data and therapeutic response one month after the start of treatment. RESULTS The clinical records of twenty-two patients diagnosed with OP were reviewed. The serum KL-6 level was elevated in 11 of the 22 patients. There were no obvious differences in the clinical data between the two groups, although patients in the normal KL-6 group tended to have a fever. There were no significant differences in the chest X-ray (CXR) score or computed tomography (CT) score between the two groups. The CXR scores were correlated with the serum KL-6 levels. At 1 month after the diagnosis, 11 patients who needed treatment with prednisolone were included in the high KL-6 group. CONCLUSIONS Patients with normal KL-6 levels showed lower CXR and CT scores. The serum KL-6 level on admission is a useful marker to judge the need for corticosteroid treatment in OP patients.

Abstract
BACKGROUND AND PURPOSE The prevalence and topography of small hypointense foci suggesting microbleeds on 3T SWI in various types of dementia have not been systematically investigated. The purpose of this study was to determine the prevalence and topography of SHF on 3T SWI in patients with different dementia subtypes. MATERIALS AND METHODS We included 347 consecutive patients (217 women, 130 men; age range, 42-93 years; mean age, 74 years) who attended our memory clinic and underwent 3T SWI. They were divided into 6 groups: subjective complaints, MCI, AD, DLB, VaD, and FTLD. Two neuroradiologists evaluated the number and location of SHF on SWIs. Statistical analyses were performed to evaluate inter- and intragroup differences. RESULTS Of the 347 patients, 160 (46.1%) exhibited at least 1 small hypointense focus. This was true in 86% with VaD, 54% with DLB, 48% with AD, 41% with MCI, 27% with FTLD, and 22% with subjective complaints. With the subjective complaints group as a reference, the odds ratio adjusted by age, sex, and arterial hypertension was 9.2 (95% CI, 2.0-43.6) for VaD; 5.4 (95% CI, 1.2-24.3) for AD; 3.1 for DLB (95% CI, 1.1-8.8); 2.0 for MCI (95% CI, 0.5-8.1); and 1.5 for FTLD (95% CI, 0.4-5.4). There was a significant lobar predilection for AD, DLB, and FTLD groups (P < .05). CONCLUSIONS On 3T SWI, patients with VaD, AD, and DLB manifested a high SHF prevalence. In patients with AD, DLB, and FTLD, the SHF exhibited a lobar predilection.

Abstract
BACKGROUND Inflammatory reactions and oxidative stress, which are important in progression of atherosclerosis, are reported to be increased in individuals with metabolic syndrome (MetS). On the other hand, adiponectin levels are lowered. Since effects of pitavastatin on these parameters have not been reported in hypercholesterolemic patients with MetS, the present study was conducted. PURPOSE To evaluate the effects of pitavastatin on inflammatory reaction, oxidative stress, and plasma adiponectin levels in hypercholesterolemic MetS patients in a multicenter trial. METHODS This open-label, single group study was performed at 7 hospitals in Japan. Pitavastatin (2mg/day) was administered to 103 consecutive patients with hypercholesterolemia, subdivided into MetS and non-MetS for 12 weeks. Blood samples were collected after overnight fasting at the start of treatment (baseline) and after 12 weeks. RESULTS In the patients with MetS (n=69), mean values of plasma high-sensitivity C-reactive protein (hs-CRP) were significantly higher and mean values of plasma high-molecular-weight (HMW)-adiponectin significantly lower than in their counterparts without MetS (n=34). The baseline HMW-adiponectin and high-density lipoprotein cholesterol (HDL-C) values significantly correlated only in the MetS patients (r=0.318; p=0.01). In an effectiveness analysis including 94 patients (62 with MetS, 32 without MetS), the level of hs-CRP was significantly decreased in patients with MetS during the drug treatment, whereas HMW-adiponectin did not change. When patients with MetS were divided into two subgroups according to the percent changes in HDL-C, significantly greater increase in HMW-adiponectin by pitavastatin treatment was observed in the HDL-C ≥10% increase subgroup than in the HDL-C <10% increase subgroup (p=0.009). CONCLUSION Twelve weeks administration of pitavastatin, in addition to the antihyperlipidemic effects, may be beneficial as an anti-atherosclerotic therapy in hypercholesterolemic patients with MetS, taking changes in hs-CRP and HMW-adiponectin into consideration. ClinicalTrials.gov identifier: NCT00444717.

Abstract
Background Nitric oxide (NO) has been reported to be a key mediator in hepatocyte proliferation during liver regeneration. NO is the oxidative metabolite of L-arginine, and is produced by a family of enzymes, collective termed nitric oxide synthase (NOS). Thus, administration of L-arginine might enhance liver regeneration after a hepatectomy. Another amino acid, L-glutamine, which plays an important role in catabolic states and is a crucial factor in various cellular and organ functions, is widely known to enhance liver regeneration experimentally. Thus, the present study was undertaken to evaluate the effects of an L-arginine supplement on liver regeneration, and to compared this with supplementation with L-glutamine and L-alanine (the latter as a negative control), using a rat partial hepatectomy model. Methods Before and after a 70% hepatectomy, rats received one of three amino acid solutions (L-arginine, L-glutamine, or L-alanine). The effects on liver regeneration of the administered solutions were examined by assessment of restituted liver mass, staining for proliferating cell nuclear antigen (PCNA), and total RNA and DNA content 24 and 72 hours after the operation. Results At 72 hours after the hepatectomy, the restituted liver mass, the PCNA labeling index and the DNA quantity were all significantly higher in the L-arginine and L-glutamine groups than in the control. There were no significant differences in those parameters between the L-arginine and L-glutamine groups, nor were any significant differences found between the L-alanine group and the control. Conclusion Oral supplements of L-arginine and L-glutamine enhanced liver regeneration after hepatectomy in rats, suggesting that an oral arginine supplement can clinically improve recovery after a major liver resection.

Abstract
Japanese paddy rice systems commonly adopt the rotation of vegetables, wheat and soybeans with paddy rice. Crop rotation may, however, increase the nutrient load in effluent discharged from the district because more fertilizer is applied to the rotation crops than is applied to paddy crops. We investigated a paddy-field district subject to collective crop rotation and quantified the annual nutrient load of effluent from the district in three consecutive years. The total annual exports of nitrogen and phosphorus over the investigation period ranged from 30.3 to 40.6 kg N ha(-1) and 2.62 to 3.13 kg P ha(-1). The results suggest that rotation cropping increases the effluent nutrient load because applied fertilizer is converted to nitrate, and surface runoff is increased due to the absence of shuttering boards at the field outlets.

Abstract
BACKGROUND/AIMS Rapid removal of plasma amyloid-β (Aβ) by blood purification may serve as a peripheral Aβ sink from the brain for Alzheimer's disease therapy. We investigated the reduction of plasma Aβ during hemodialysis and cognitive states. METHODS Aβ concentrations and Mini-Mental State Examinations (MMSE) were investigated in 37 hemodialysis patients (68.9 ± 4.1 years). RESULTS The dialyzers effectively removed Aβ(1-40) and Aβ(1-42), 63.9 ± 14.4 and 51.6 ± 17.0% at 4 h dialysis, resulting in the reduction of Aβs in whole-body circulation by 51.1 ± 8.9 and 32.7 ± 12.0%, respectively. Although the plasma Aβs before dialysis (750.8 ± 171.3 pg/ml for Aβ(1-40)) were higher than those reported for Alzheimer's disease patients, the cognitive states of hemodialysis patients were relatively normal, especially of longer dialysis vintages. CONCLUSIONS Dialyzers effectively reduced Aβs in whole-body circulation. Repeated rapid decrease of plasma Aβs might maintain cognitive state.

Abstract
In accordance with the revision of the "Organ Transplantation Law", the ordinances and the guideline for the law were also revised. The revision of the guideline, which finds legal basis on the circular notices, raises some issues about its position in the Japanese legislative system. It is quite ambiguous whether we should comprehend the guideline as the interpretation of the law, as the procedural guidance, or as the instruction within the administrative body. Thus, the legal obligation for the healthcare professionals to observe the guideline is also unclear. There are many issues about the transplantation law, the ordinances and the guideline. They include (1) Legal implication of the "brain death" (Is "brain death" absolutely synonymous with "death" ?), (2) Scientific relevance of the criteria for diagnosis of brain death, (3) Definition of the "adequate treatment" which is the prerequisite for diagnosis of brain death, (4) The time of death for the cases who were declared legally brain-dead but did not donate the organs, (5) By whom and when should the organ donation be proposed, and more. The ambiguity about the legal position of the guideline shall cause confusion in the scenes of clinical practice.

Abstract
A complementary DNA (cDNA) macroarray was developed for simultaneous detection of 12 different potato viruses. A suitable region in the viral genome for each was selected for Alfalfa mosaic virus, Cucumber mosaic virus, Potato aucuba mosaic virus, Potato leafroll virus, Potato mop-top virus, Potato virus A, Potato virus M, Potato virus S, Potato virus X, Potato virus Y, Tomato ringspot virus, and Tomato spotted wilt virus, and their respective cDNAs were cloned into plasmid vectors. Capture probes for each virus ranging from 290 to 577 bp were generated by polymerase chain reaction (PCR) and immobilized on a nylon membrane. Total RNAs were extracted from each of these virus infected-plants, and cDNAs were synthesized from the RNA extracts using a random 9-mer primer. Subsequently, PCR reactions were performed using one primer pair for each of the 12 viruses. During PCR, amplified cDNAs were labeled with biotin and used as a target for hybridization analyses on a macroarray membrane. Hybridization signals between capture probes for the 12 viruses and their respective target cDNAs were observed using chemiluminescent or colorimetric detection. In all viruses, hybridization signals with capture probes were detected only when homologous virus targets were examined, and no hybridization to healthy plant extract was observed, facilitating identification of each virus. The results by colorimetric detection agreed with those obtained using chemiluminescence. The macroarray method developed was 5 × 102 to 4 × 106 times more sensitive than enzyme-linked immunosorbent assay and 5 to 5 × 104 times more sensitive than reverse-transcription PCR, except for Alfalfa mosaic virus. Colorimetric detection and substantial reduction in cross-hybridization signals much improved the method compared with other array-based detection methods for practical use.

Abstract
AIM The present study was undertaken to evaluate the effects of 1-O-hexyl-2,3,5-trimethylhydroquinone (HTHQ), a synthesized vitamin E derivative, on carbon tetrachloride (CCl(4))-induced cirrhosis. METHODS Rats were treated with hypodermic injections of CCl(4) twice a week to induce the hepatic cirrhosis, and given drinking water containing HTHQ or solvent. Primary cultures of rat hepatocytes were performed to evaluate the effects of HTHQ on the expression of inducible nitric oxide synthase (iNOS). RESULTS Masson's staining of rat livers showed fibrosis around pseudo-lobules in the CCl(4) group, the lesions being reduced in the CCl(4) HTHQ group. Increases in liver tissue hydroxyproline and alpha(1)(I) collagen, alpha-smooth muscle actin and iNOS induced by CCl(4), were also markedly diminished by HTHQ. Furthermore, both HTHQ and vitamin E attenuated interleukin-1beta-induced iNOS protein expression in cultured hepatocytes, the potency of HTHQ being 10-times higher than that of vitamin E. CONCLUSION HTHQ may inhibit development of hepatic cirrhosis in rats, more potently than vitamin E, by inhibiting the iNOS expression in hepatocytes. Because vitamin E has a radical scavenging action, roles of NO and peroxynitrite will be discussed in the effects of HTHQ on the fibrosis.

Abstract
Purpose: Spontaneous hemopneumothorax (SHP) is a rare life threatening disorder. We retrospectively investigated patients with SHP who were treated with video- assisted thoracic surgery (VATS), and report our results. Methods: From January 1993 to July 2006, 239 patients with spontaneous pneumothorax were treated, among whom 11 (4.6%) were diagnosed with SHP. Results: All 11 patients had a collapsed lung condition worse than moderate and a chest tube inserted, of whom 10 underwent an emergency operation. The points of hemorrhaging, each of which were in the apical portion of the lung, were easily revealed during VATS, and we were able to distinguish between brisk flow and seepage. Hemostasis was acquired using VATS in all surgery cases, while the other was treated with tube drainage. The single patient who did not undergo surgical treatment had recurrent spontaneous pneumothorax 3 months later. Conclusion: It is important to perform surgery for SHP at the appropriate time. VATS was found to be an easily performed and safe procedure for initial treatment in patients with active hemorrhaging and massive blood clotting in the thorax. The long-term outcome of our patients with early surgical indication was excellent and we recommend early surgical treatment for SHP.
