Abstract
Coronavirus disease 2019 (COVID-19) causes a systemic inflammatory response and a temporary immunosuppression of hosts. Several reports have showed that reactivation of herpes simplex virus type 1 (HSV-1) is strongly associated with COVID-19. We present a case of a 66-year-old female, who developed HSV-1 encephalitis, showing impaired consciousness and typical MRI findings such as hyperintense lesions in the temporal lobe, insular cortices, bilateral medial frontal lobe on diffusion-weighted imaging, 7 days after the onset of COVID-19 symptoms. The number of cases of encephalitis in patients with COVID-19 is increasing. However, there has been limited reports of HSV-1 encephalitis following COVID-19, especially for cases with an interval of 7 days or less from the onset of COVID-19 symptoms to the onset of HSV-1 encephalitis. Our case highlights the importance of considering HSV-1 encephalitis in the differential when managing a patient with COVID-19-associated neurologic complications, even if it is in the early stages of COVID-19.

Abstract
A 75-year-old woman presented with nausea and vomiting. Magnetic resonance imaging (MRI) revealed that she had a pituitary mass. A biopsy revealed lymphocytic hypophysitis (LYH). Symptoms were improved by hormone replacement therapy. Although she was asymptomatic, follow-up MRI revealed an increase in the size of the mass. Intravenous methylprednisolone (IVMP) reduced the size of the mass; however, right ophthalmalgia and oculomotor nerve palsy developed. MRI showed that the pituitary mass had enlarged to the right oculomotor nerve in the cavernous sinus and to the right internal carotid artery (ICA), causing stenosis of the ICA. After IVMP administration, the symptoms dramatically improved, but ICA stenosis persisted.

Abstract
Background The terminal complement C5 inhibitor eculizumab is approved in Japan for relapse prevention in aquaporin-4 antibody-positive (AQP4+) neuromyelitis optica spectrum disorder (NMOSD) and is undergoing mandatory post-marketing surveillance (PMS) of clinical use. Objectives The objective of the study is to assess the real-world, long-term safety and effectiveness of eculizumab in Japanese patients with AQP4+ NMOSD. Design Regulatory-mandated PMS analysis implemented as an all-case surveillance of all patients with AQP4+ NMOSD who have been treated with eculizumab in Japan since its approval in November 2019. Methods This PMS interim analysis assessed the safety and effectiveness of eculizumab in Japanese patients with AQP4+ NMOSD from November 2019 to April 2022. Results Of 147 patients treated with eculizumab who consented to publication, 71 had at least one case report form collected and locked at the interim analysis data cut-off, constituting the safety analysis set; three patients from PREVENT (NCT01892345) were excluded from the effectiveness analysis set. Twelve and 10 patients in the safety and effectiveness analysis sets discontinued, respectively. In the safety analysis set, 67/71 patients (94.4%) were female, mean illness duration was 6.8 [standard deviation (SD): 6.2] years, mean age at eculizumab initiation was 50.7 (SD: 13.3) years, and mean eculizumab treatment duration was 44.6 (SD: 23.7) weeks. At diagnosis of NMOSD, 34/71 patients (47.9%) and 35/71 patients (49.3%) in the safety analysis set had symptoms of optic neuritis and transverse myelitis, respectively. In the safety analysis set, 19/71 patients (26.8%) reported adverse events, 10/71 (14.1%) reported adverse drug reactions (ADRs), and 7/71 (9.9%) reported serious ADRs; no meningococcal infections were observed. In the effectiveness analysis set, 64/68 patients (94.1%) were female, mean disease duration was 6.9 (SD: 6.3) years, mean age at eculizumab initiation was 50.6 (SD: 13.2) years, and 27/68 (39.7%) were tested for C5 genetic polymorphism (all negative). In the 2 years before eculizumab, 51/68 patients (75.0%) experienced relapse. Relapse rate was 0.02/patient-year after eculizumab initiation versus 0.74/patient-year in the 2 years before eculizumab. Overall, 37/68 patients (54.4%) were prescribed immunosuppressants in the 6 months before and 19/40 (47.5%) in the 6-12 months after starting eculizumab treatment. The proportion of patients taking >10 mg/day of prednisolone decreased from 45.6% at 24-20 weeks before to 23.1% and 0% at 48-52 and 100-104 weeks after eculizumab, respectively. Conclusion This article reports interim PMS data for Japanese patients and provides updated real-world evidence for the safety of eculizumab and its effectiveness at preventing relapses in patients with AQP4+ NMOSD. Safety and effectiveness results are consistent with those from PREVENT.

Abstract
To investigate the prevalence and genotype-phenotype correlations of phosphatase and tensin homolog induced putative kinase 1 (PINK1) variants in Parkinson's disease (PD) patients, we analyzed 1700 patients (842 familial PD and 858 sporadic PD patients from Japanese origin). We screened the entire exon and exon-intron boundaries of PINK1 using Sanger sequencing and target sequencing by Ion torrent system. We identified 30 patients with heterozygous variants, 3 with homozygous variants, and 3 with digenic variants of PINK1-PRKN. Patients with homozygous variants presented a significantly younger age at onset than those with heterozygous variants. The allele frequency of heterozygous variants in patients with age at onset at 50 years and younger with familial PD and sporadic PD showed no differences. [123I]meta-iodobenzylguanidine (MIBG) myocardial scintigraphy indicated that half of patients harboring PINK1 heterozygous variants showed a decreased heart to mediastinum ratio (12/23). Our findings emphasize the importance of PINK1 variants for the onset of PD in patients with age at onset at 50 years and younger and the broad spectrum of clinical symptoms in patients with PINK1 variants.

Abstract
Background Necrotizing myopathy (NM) is defined by the dominant pathological feature of necrosis of muscle fibers without substantial lymphocytic inflammatory infiltration. Anti-signal recognition particle (SRP)-antibody-positive myopathy is related to NM. Anti-SRP-antibody-positive myopathy can comorbid with other disorders in some patients, however, comorbidity with malignant tumor and myopericarditis has still not been reported. Case presentation An 87-year-old woman with dyspnea on exertion and leg edema was referred to our hospital because of suspected heart failure and elevated serum creatine kinase level. Upon hospitalization, she developed muscle weakness predominantly in the proximal muscles. Muscle biopsy and immunological blood test led to the diagnosis of anti-SRP-antibody-positive myopathy. A colon carcinoma was also found and surgically removed. The muscle weakness remained despite the tumor resection and treatment with methylprednisolone. Cardiac screening revealed arrhythmia and diastolic dysfunction with pericardial effusion, which recovered with intravenous immunoglobulin (IVIg) treatment. Conclusions We reported the first case of anti-SRP-positive myopathy comorbid with colon carcinoma and myopericarditis. This case is rare in the point that heart failure symptoms were the first clinical presentation. The underlying mechanism is still not clear, however, physicians should be carefully aware of the neoplasm and cardiac involvement in anti-SRP-antibody positive-myopathy patients and should consider farther evaluation and management.

Abstract
A 69-year-old man was admitted with neck muscle weakness, symmetric proximal muscle weakness, skin rash and elevated serum creatine kinase levels. Muscle biopsy showed perifascicular necrosis and perimysial alkaline phosphatase activity. Chest CT revealed interstitial lung disease and colorectal cancer was diagnosed on colonoscopy. He was serologically positive for anti-EJ antibody, leading to the diagnosis of antisynthetase syndrome (ASS). After laparoscopic low anterior resection of the rectum, he received intravenous methylprednisolone (1,000 mg/d for 3 days) followed by oral prednisolone (50 mg/d). Although his muscle weakness improved after corticosteroid therapy, he developed pericardial effusion with resultant asymptomatic hypotension and arrhythmia possibly due to pericarditis. Corticosteroid monotherapy was insufficient to control the disease, and, we decided to use oral cyclosporin concurrently. After this combined therapy started, pericardial effusion and arrhythmia were improved. We should keep in mind that pericarditis can occur in patients with anti-EJ antibody-positive ASS, and early combined therapy with corticosteroid and immunosuppressive drugs for ASS may improve the patient's prognosis.

We investigated the association between prestroke medication and poststroke delirium. MATERIALS AND METHODS All patients hospitalized in the stroke care unit from September 2011 to September 2012 were selected, and their delirium symptoms, patient information, and pre- and poststroke medications were analyzed. Delirium was defined as a score of 4 or higher on the Intensive Care Delirium Screening Checklist. Factors that were related to delirium were extracted using univariate analysis, and the independent risk factors were determined using multivariate analysis. RESULTS Of the 269 patients analyzed, 97 (36%) experienced delirium. Univariate analysis revealed significant differences between the delirium and nondelirium groups in age, dementia, previous cerebrovascular disease, craniotomy, all insertion-tube types, and 6 categories of prestroke medication. Prestroke polypharmacy was associated with poststroke delirium (P = .002). Multivariate analysis showed that taking antianxiety agents or sleep aids was an independent risk factor for delirium (odds ratio: 3.17, 95% confidence interval: 1.16-8.82). CONCLUSIONS The present study suggests that prestroke medication affects the onset of poststroke delirium. These findings can contribute to the prediction and prevention of this condition.

Abstract
Background Although predicting future brain volume loss (BVL) in patients with multiple sclerosis (MS) is important, studies have shown only a few biomarkers that can predict BVL. Objectives The aim of this study is to elucidate the association between longitudinal BVL and serum biomarker candidates. Methods This single-center, retrospective, observational study intended to cover MS patients during January 2008 to March 2016. Patients who underwent brain MRI two times at intervals of >24 months and had a blood test to measure biomarker candidates at the time or within three months of the MRI scan were included. Evaluation of brain volume was performed by using SIENAX and SIENA in the FMRIB software library. Results Twenty-three patients with MS were included in this study. We found that serum retinol binding protein (RBP) levels were significantly correlated with percentage brain volume change (PBVC) (p = 0.0079). Furthermore, best subset selection of multiple linear regression models identified baseline normalized brain volume and serum RBP as the best predictors of PBVC. Conclusions Our study shows that lower serum retinol levels are associated with greater longitudinal BVL and that serum RBP and can be a predictor of BVL.

Abstract
Recent developments of the interventional neuroradiological technique made percutaneous transluminal angioplasty (PTA) possible even for intracranial arteries1. We report our experiences of 17 cases treated by PTA including 9 intracranial internal carotid (ICA), 4 middle cerebral (MCA) and 4 vertebro-basilar arterial (VBA) stenoses and discuss the problems of the procedure. All patients had cerebral ischemic symptoms and stenoses more than 60% calculated angiographically. Three of them were treated by PTA for residual stenoses after thrombolytic therapy for acute occlusion. We used PTA balloon catheters 2.0 mm to 3.5 mm in diameter (Stealth, Target therapeutics) for all PTA procedures. A PTA balloon was inflated for 1 min at 6 atm as a rule. All were successfully dilated (stenosis less than 50%) except one treated by PTA for residual MCA stenosis after thrombolytic therapy. The patient died from massive infarction due to MCA re-occlusion caused by MCA dissection. Restenosis appeared in 4 of 16 patients. Repeated PTA was successfuly carried out for the 4 patients. However, restenosis appeared in one of them but the patient is now on follow-up because of asymptomatic course. PTA for intracranial arteries is an effective treatment but its indication should be determined strictly because of potential risk such as acute occlusion derived from dissection.

Abstract
We treated 7 cases of dural arteriovenous fistulas (dAVF) with isolated sinus by transvenous direct embolization. The fistulas located in the transverse-sigmoid sinus in 5 cases, superior sagittal sinus in 1 case and transverse-sigmoid and superior sagittal sinus in 1 case. The initial symptoms were generalized convulsion in 2 cases, disturbed consciousness in 1 case, tinnitus in 2 cases and transient ischemic attack in 2 cases. We performed sinus packing with coils in all cases following transarterial embolization. All patients improved neurologically after the treatments and AVFs completely disappeared in all cases.

Abstract
Seventy four cases of internal carotid stenoses greater than 60% were treated by PTA and/or stenting 86 times. Sixty one cases of cervical ICA stenosis were treated 71 times. 11 cases of high cervical - intracranial ICA stenosis were treated 13 times. Two cases of ICA dissection were treated by stent deployment. Stenotic ratio reduced from 79% to 29% in cervical ICA stenosis and 71 % to 32% in high cervical to intracranial ICA stenosis in average. Morbidity related to PTA and/or stenting was 2/74 (2.7%) and mortality was 0%. One was an ischemic complication and the other was a hemorrhagic complication due to hyperperfusion. Restenosis (stenosis greater than 70%) rate was 32%. Asymptomatic cerebral embolism were found in three cases (4.2%) on angiogram immediately after PTA and/or stenting. The complication rate related to PTA and/stenting was low but asymptomatic emboli were found in three cases. Considering these results, the indication for PTA and/stenting should be restricted to patients with high risk group, such as cases with high medical risks or difficult CEA cases, if appropriate protective systems for cerebral emboli were not available.

Abstract
OBJECTIVES Clinical and pathological significance of gadolinium (Gd)-enhancing pattern on magnetic resonance imaging (MRI), including ring enhancement (RE), is well documented in multiple sclerosis but not in neuromyelitis optica (NMO), especially in the spinal cord. The purpose of this study is to examine the prevalence of spinal cord RE in NMO and to determine the association between clinical characteristics and spinal cord RE. MATERIALS AND METHODS We retrospectively examined Gd-enhanced spinal cord MRI scans, during the acute phase, in patients with anti-aquaporin 4-positive NMO, including NMO spectrum disorder. We then analysed their clinical features and MRI imaging characteristics of spinal cord lesions. RESULTS Of the 30 patients with NMO, we enrolled 12 patients with 16 Gd-enhanced spinal cord MRI scans in this study. Five scans revealed RE (31.2%). Male ratio, as well as myelin basic protein (MBP) levels, in the cerebrospinal fluid (CSF) of patients with RE was significantly higher than those of patients without RE (P = 0.018, P = 0.026, respectively). CONCLUSIONS Spinal cord RE is common in patients with NMO. Higher MBP levels in the CSF of patients with RE can be associated with a higher degree of myelin damage.

Abstract
Serum amyloid A (SAA) is known to promote the development of T helper 17 cells (Th17) and can be a critical mediator of disease pathogenesis. We analyzed SAA levels in 40 patients with multiple sclerosis (MS) and related disorders, and 10 with non-inflammatory neurological disease (NIND) as controls. We found that SAA levels were significantly increased in neuromyelitis optica (NMO) patients and relapsing and remitting MS (RRMS) patients showing atypical phenotype with spinal cord lesions and smaller T2 lesion volume in brain MRI, resembling NMO. Therefore, SAA levels can be associated with clinical phenotypes in MS and NMO.

Abstract
Improved hygiene has been suggested to influence certain autoimmune disorders, such as multiple sclerosis. In this study, we addressed whether altering the composition of gut flora may affect susceptibility to experimental autoimmune encephalomyelitis (EAE), an animal model of MS. We administered a mixture of non-absorbing antibiotics, kanamycin, colistin, and vancomycin (KCV), orally to mice induced to develop EAE. The antibiotic treatment, beginning 1 week prior to sensitization, altered the composition of gut flora and, intriguingly, also ameliorated the development of EAE. While this result was associated with a reduced production of pro-inflammatory cytokines from the draining lymph node cells, a reduction of mesenteric Th17 cells was found to correlate with disease suppression. In addition, we found that Valpha14 invariant NKT (iNKT) cells were necessary for maintaining the mesenteric Th17 cells. The homologous effects of KCV treatment and iNKT cell depletion led us to speculate that KCV treatment may suppress EAE by altering the function of iNKT cells. Consistent with this hypothesis, KCV treatment did not suppress EAE that was induced in iNKT cell-deficient mice, although it was efficacious in mice that lacked Valpha19 mucosal-associated invariant T cells. Thus, gut flora may influence the development of EAE in a way that is dependent on iNKT cells, which has significant implications for the prevention and treatment of autoimmune diseases.

Abstract
OBJECTIVES Although hyperhomocyst(e)inemia had been proven to be a potent risk factor for ischemic stroke, it is still controversial which subtype of stroke is associated with hyperhomocyst(e)inemia. The aim of this study was to clarify the association between plasma homocyst(e)ine (Hcy) levels and stroke subtypes according to TOAST classifications based on MRI findings. METHODS We prospectively recruited 124 consecutive first-ever ischemic stroke patients hospitalized in Toride Kyodo General Hospital. Each patient underwent brain MRI including diffusion-weighted imaging (DWI) and was evaluated for total plasma Hcy levels in addition to routine laboratory tests. RESULTS Of the 93 patients enrolled in this study, 19 were subtyped with large-artery atherosclerosis with acute multiple brain infarction [LA-AMBI(+)], 13 with LA-AMBI(-). Patients with LA-AMBI(+) showed significantly higher plasma Hcy levels than those with LA-AMBI(-). Moreover, for LA-AMBI, the plasma Hcy level was associated with an OR of 1.3 (95% CI 1.06-1.71, P=0.017) per 1 mumol increase in concentration, and 1.4 (95% CI 1.04-1.77, P=0.025) after adjustment for age, sex and serum cholesterol levels. CONCLUSION In the subset of patients with LA strokes, those with high Hcy levels are more likely to have AMBI than those without elevated Hcy levels possibly due to plaque instability.

Abstract
We obtained the venograms using the two-dimensional digital subtraction angiography (2D DSA) images and three dimensional rotation venography (3D RV) images and investigated the potential usefulness of the 3D RV compared with venograms of 2D DSA using the newly developed three-dimensional rotation angiography unit with a flat-panel detector (FPD). This study included 26 sides (11 left, 15 right) in 20 cases (4 males and 16 females) who underwent radiographic examination for management of intracranial tumors and vascular diseases between May 2003 and December 2003. Each patient underwent diagnostic angiography performed on a DSA unit with a FPD. In all patients, the 2D DSA images, including anteroposterior view and lateral view of the carotid artery, were obtained in two stereoscopic views. The 3D RV was used to produce volume-rendered images. Two neuroradiologists investigated the venous configuration of 3D RV compared with that of 2D DSA about the relationship of the venous drainage system on the temporal lobe according to Guppy et al.'s classification. Twenty-four sides of the 26 sides enabled the precious visualization on 3D RV images. In investigation of 2D DSA, 9 sides (37.5%) were classified into type A, 13 (54.2%) into type B, two (8.3%) into type C, and no sides into types D, E, and F. In investigation of 3D RV images, 10 sides (41.7%) were classified into type A, 9 (37.5%) into type B, 1 (4.2%) into type C, 2 (8.3%) into type E, and 2 (8.3%) into type F. Seven of 24 sides demonstrated discrepancy in results between 2D DSA and 3D RV. The 3D RV could be performed by setting the adequate delay in between the injection of the contrast material and starting time of third rotation to acquire the opacified images. In Guppy et al.'s classification, the 3D RV images could demonstrate the precious venous drainage including the venous lakes with use of multiple views and variable reconstruction compared with 2D DSA. Our DSA system with FPD could provide good 3D RV images. These images are very useful for the skull-base surgery because we can understand the three-dimensional vascular anatomy preoperatively.

Abstract
A 69-year-old Japanese man suddenly developed monoplegia of left lower extremity, followed by paraplegia and finally by tetraplegia. MRI revealed an infarction in bilateral medial medulla extending from the cervicomedullary junction up to the upper limit of the medulla. Both hypoglossal nerve palsy and sensory disturbance were absent. At the pyramidal decussation, fibers to the lower extremities cross caudal to the fibers going to the upper extremities, therefore right below the decussation, fibers to the lower extremities run medial side of the fibers to the upper extremities, but later the former run lateral side of the latter. In this patient, the authors considered that the lesion initially damaged the pyramidal decussation at a slightly lower level, involving the tract to left lower extremity, and then extended to right lower extremity, to the left upper extremity, finally to the right upper extremity. Bilateral medial medullary infarction must be considered in the clinical course seen as in this patient.

Abstract
We report results and problems of the endovascular treatment in 12 cases of intradural vertebral dissecting aneurysm presenting with subarachnoid hemorrhage. There were four complications related to interventional procedure and conventional angiography. In three patients (25%), VDAs ruptured immediately after injection of contrast media or hypertension during the interventional procedure, which caused respiratory arrest. In a case of bilateral VA dissection (8%), after proximal VA occlusion had been performed for unilateral VDA, contralateral dissection extended to the basilar artery resulting in brain stem infarct. We suggest that the incidence of rebleeding of VDA during angiography and embolization is higher than that of usual saccular aneurysms. Careful injection of contrast media and strict blood pressure control seems to be more important to prevent rebleeding in VDAs than intracranial saccular aneurysms. Since unilateral VA occlusion may extend contralateral dissection in a case of bilateral VA dissection, it is necessary to check contralateral VA dissection before VA occlusion.

Abstract
SUMMARY Thirty-two patients with intracranial aneurysm were treated via the endovascular approach and clinical results and complications were accessed. The aneurysms were on the anterior circulation, posterior circulation and feeding artery of AVM in 17, 12 and three patients respectively. In 17 (anterior circulation aneurysm), 12 patients underwent parent artery occlusion. There were two complications: cerebral embolism due to premature detachment of balloons and cerebral infarct due to parent artery occlusion. In 12 (posterior circuration aneurysm), four patients had complications: three infarcts due to parent artery occlusion and one aneurysmal bleeding at the interventional procedure. Coil compactions occurred in four cases. There were no complications in cases associated with AVM. Use of detachable balloons for intra-aneurysmal occlusion and intra-aneurysmal embolisation for partially thrombosed giant aneurysm tends to result in ischemic lesions where patient outcome is poor. We must pay attention to avoid these complications even though intra-aneurysmal embolisation using microcoils is currently performed safely.

Abstract
Recent advances in MR hydrography have enabled various clinical applications in the areas of abdominal and pelvic disorders, for example, MR cholangiopancreatography (MRCP), MR urography(MRU), and MR hydrography of the fetus. Although the two-dimensional(2D) single-slice method provides excellent information as to the global relationship between lesions and various anatomical structures, small lesions or detailed anatomical characteristics may not be visualized owing to the partial volume effect. Source images of the 2D multislice method are most suitable for the detection of small lesions and detailed evaluation of anatomical structures as "tomographic imaging", while the three-dimensional(3D) method is useful in obtaining data sets for 3D imaging. MR hydrography is a promising method for the noninvasive evaluation of various abdominal disorders, and it has the potential to play new roles in various anatomical regions. However, knowledge of the proper indications is essential for successful clinical application.

Abstract
OBJECT The P19 embryonal carcinoma-derived cell line consists of undifferentiated multipotential cells, which irreversibly differentiate into mature neurons after exposure to retinoic acid (RA). In the present study, the authors genetically engineered P19 cells to produce glial cell line-derived neurotrophic factor (GDNF), and grafted the cells in a rat model that had been rendered parkinsonian. METHODS Undifferentiated P19 cells were grown in vitro and transduced with GDNF complementary DNA. The level of GDNF released from the transduced cells was measured using an enzyme-linked immunosorbent assay, and its neurotrophic activities were assessed by testing the effects on rat embryonic dopamine (DA) neurons in culture. After having been exposed to RA for 48 hours and allowed to differentiate into postmitotic neurons, the GDNF gene-transduced cells were implanted into the midbrain of immunosuppressed rats. A unilateral nigrostriatal lesion was then induced by intrastriatal infusions of 6-hydroxydopamine. Immunohistochemical analyses performed 4 weeks postgrafting revealed that the GDNF-producing cells expressed several neuronal markers without evidence of overgrowth. The grafts expressed GDNF protein and prevented the death of nigral DA neurons. Furthermore, the GDNF-producing cells implanted 4 weeks after nigrostriatal lesions restored the expression of tyrosine hydroxylase in injured DA neurons and induced their dendritic sprouting. CONCLUSIONS The results indicate that the P19 cell line transduced with the GDNF gene can stably secrete functional levels of GDNF, even after being converted to postmitotic neurons. Because it is has been established that GDNF exerts trophic effects on DA neurons, the means currently used to deliver GDNF into the brain could be a viable strategy to prevent the death of nigral DA neurons in cases of Parkinson's disease.

Abstract
The efficacy of repeated percutaneous transluminal angioplasty (PTA) and carotid endarterectomy (CEA) was examined in patients with restenosis after PTA for carotid stenosis. After percutaneous transluminal angioplasty (PTA) for 63 cases of internal carotid stenoses 13 cases of restenosis appeared. They were treated by PTA or carotid endarterectomy. The treatment was chosen by the patient after explanation of each treatment. We initially treated seven patients by repeat PTA and six by carotid endarterectomy. The degree of stenosis improved from 82% to 30% on average after repeated PTA. However, one patient in the PTA group had restenosis, and carotid endarterectomy was then performed. The other cases also had restenosis and were treated by PTA. The six cases treated by carotid endarterectomy were successfully treated without difficulty. The success rate of PTA was 5/7 (71%) in the restenosis cases. Patients with a greater residual stenosis after initial PTA had significantly more frequent restenosis. Repeat PTA and CEA both appeared effective treatment for restenosis after initial PTA, although PTA had a restenosis rate similar to that of initial PTA.

Abstract
It is known that Bcl-2 has a protective effect against neuronal ischemia. Some reports speculate anti-apoptotic function of Bcl-2 depends not on the expression level but on the phosphorylation state. We found induction of apoptosis and CPP32 activation by energy impairment (3-nitropropionic acid (3-NP)-treatment or glucose-deprivation) in the neuronally differentiated P19 cells. Time course study of cell viability following ischemic insults showed that the number of viable cells decreased along with the increase in the amount of dephosphorylated Bcl-2 without obvious quantitative alteration of the protein. Then, we generated differentiated P19 cells overexpressing wild-type Bcl-2 (P19/wt. Bcl-2) or phosphorylation-negative Bcl-2 mutant (P19/mut.Bcl-2), in which alanine was substituted for serine 70. When the cell viability was examined within 24 h, P19/mut.Bcl-2 was more vulnerable to energy impairment as compared with P19/wt.Bcl-2. In addition, overexpression of wild-type Bcl-2 inhibited DNA laddering and CPP32 activation induced by the insults, while that of mutant Bcl-2 did not. These findings suggest that the phosphorylation state, as well as the expression level, of Bcl-2 plays an important role to modulate its protective effect against ischemic insults.

Abstract
A 58-year-old woman with a presumed incidentally discovered meningioma in the left lateral ventricle was treated by superselective embolisation and gamma knife therapy. The diameter of the tumour was 40 mm, and its main feeding artery was the left lateral posterior choroidal artery. This vessel was embolised with microcoils. At 8 months following embolisation, the diameter of the tumour had decreased and was stable. The gamma knife was chosen as an adjuvant therapy for the further control 13 months after embolisation. Embolisation and gamma knife therapy may be an alternative treatment for meningiomas where surgical resection appears difficult.

Abstract
To elucidate the role of high mobility group 2 protein (HMG2) in cis-diamminedichloroplatinum (II) (cisplatin, CDDP) sensitivity, we constructed a human HMG2-transfected human non-small cell lung cancer cell line, PC-14/HMG2. The HMG2 mRNA expression level was approximately twice those of parental PC-14 and mock-transfected PC-14/CMV. Gel mobility shift assay revealed a CDDP-treated DNA-protein complex in the nuclear extract of PC-14/HMG2, which was not found in the extracts of PC-14 and PC-14/CMV. This complex formation was subject to competition by CDDP-treated non-specific salmon sperm DNA, indicating that ectopic HMG2 recognizes CDDP-damaged DNA. PC-14/HMG2 showed more than 3-fold higher sensitivity to CDDP than PC-14 and PC-14/CMV. The intracellular platinum content of PC-14/HMG2 after exposure to 300 microM CDDP was 1.1 and 1.5 times that of PC-14 and PC-14/CMV, respectively. Cellular glutathione levels were not different in these cell lines. Repair of DNA interstrand cross-links determined by alkaline elution assay was decreased in PC-14/HMG2. These results suggest that HMG2 may enhance the CDDP sensitivity of cells by inhibiting repair of the DNA lesion induced by CDDP.

Abstract
The C-terminal domain of p53 may bind single-stranded (ss) DNA ends and catalyze renaturation of ss complementary DNA molecules, suggesting a possible direct role for p53 in DNA repair (Proc. Natl. Acad. Sci. USA, 92, 9455-9459, 1995). We found that DU-86, a duocarmycin derivative which alkylates DNA, bound ssDNA and enhanced the DNA binding activity of the p53 C-terminus. DU-86 weakened p53-mediated catalysis of complementary ssDNA renaturation. p53 C-terminus catalyzed DNA strand transfer toward annealing between intact ssDNAs and toward eliminating DU-86-damaged ssDNA from duplex formation. These results suggest that p53, via the C-terminal domain, may play a direct role in DNA repair by preferential recognization and elimination of damaged DNA.

Abstract
SUMMARY Three patients with vertebral arteriovenous fistulae are described. Transarterial embolization by microcoils and balloons was used in each case and the fistula was completely occluded in one case immediately after embolization. Another two cases with partial obliteration of the fistula were followed and showed complete occlusion of the fistula after a one year follow-up. After embolization of the fistula, each patient improved in clinical signs and symptoms and showed no complications. Transarterial embolization for vertebral arteriovenous fistula is a safe and effective treatment.

Abstract
SUMMARY Thirteen cases of restenosis occurred after percutaneous transluminal angioplasty (PTA) in 63 cases of internal carotid stenoses. They were treated by PTA or carotid endarterectomy. The patients were sufficiently informed of each treatment. Seven of them were initially treated by repeated PTA. The stenosis ratio improved from 82% to 30% after repeated PTA on average. However, one case in the PTA treated group resulted in restenosis and then carotid endarterectomy was performed. The other case also caused restenosis and was treated by PTA. Six cases were initially treated by carotid endarterectomy and all cases were successfully treated without difficulty. The success rate of the PTA was 2/7 (29%) in restenosis cases. One case causing re-restenosis had severe calcification in the arterial wall. PTA was thought to be effective for the restenosis cases after initial PTA if the arterial calcification was not severe.

Abstract
SUMMARY Nineteen patients with intracranial aneurysm were treated using electrically detachable coils (GDC or IEDC) and angiographic results and complications were assessed. In 18 aneurysms treated by endosaccular occlusion, 11 (61%), 3 (17%) and 4 (22%) resulted in complete occlusion, neck remnant and dome filling, respectively. Neither haemorrhagic nor thromboembolic complications occurred in 19 patients. Embolization using electrically detachable coils seemed to be a safe and useful procedure without complications, but we should give attention to avoiding complications and incomplete occlusion in particular in a case of 1) wide-necked, 2) small (< 3 mm) or 3) complex- shaped aneurysms.
