Central anticholinergic syndrome is defined as an absolute or relative reduction in cholinergic activity in the central nervous system and has a wide variety of manfestations. It is associated with almost any drug given during anesthesia, except neuromuscular relaxants, and treated with the cholinesterase inhibitor physostigmine. The diagnosis of central anticholinergic syndrome is often made when symptoms resolve promptly after the administration of physostigmine. We present a case of a central anticholinergic syndrome diagnosed by treatment with physostigmine, in a patient who received closure of patent foramen ovale associated with stroke.

어미쥐에 유발시킨 납중독이 새끼쥐의 특정 중추신경계에 미치는 신경독성의 선택성 여부를 알아보고자 하였다. 특정 신경계의 한 예로 모노아민성 신경계를 선택하여 납중독의 지표로 모노아민성 신경계의 효소인 MAO(monoamine oxidase)의 활성을 측정하였으며 비특정조직에의 지표로 Na+.K+-ATPase의 활성을 측정하였다. 임신한 Wistar계 어미쥐에게 임신전기간에 걸쳐 0.05 혹은 0.2% 초산납(PbAc2)용액을 식수로 공급하여 간접적으로 태아에 납중독을 유발시켰다. 새끼쥐는 출생직후 정상 식수를 공급해 주었다. 2, 4, 6 및 8주된 새끼쥐의 MAO 및 Na+.K+-ATPase활성을 대뇌, 간뇌, 중뇌, 뇌교-연수 및 소뇌 등 다섯부위에서 각기 측정하였다.

Primary angiitis of the central nervous system (PACNS) is a rare vasculitis in the central nervous system. Herein, we report a case of diagnosis and treatment of necrotic pattern PACNS, which was difficult to differentiate from a brain abscess. A 19-year-old male presented with blurred vision and a headache. Brain MRI revealed irregular rim-enhancing necrotic masses with central diffusion-high signal intensity in the corpus callosum and peripheral diffusion-high signal intensity in the left parietotemporal periventricular area. Susceptibility-weighted imaging revealed multiple punctate hemorrhages in the lesions. The patient was diagnosed with unusual abscess or tumefactive PACNS. Therefore, we initially treated the patient with antibiotics to rule out brain abscess. However, the brain lesions did not improve on follow-up MRI after the antibiotic treatment. Surgical biopsy was performed, and the histopathological diagnosis was PACNS with a necrotic pattern. The necrotic lesions became smaller on follow-up MRI after high-dose corticosteroid treatment.

출생직후부터 새끼쥐에 유발시킨 납중독이 중추의 특정 신경계에 미치는 신경독성의 선택성 여부를 알아보고자 하였다. 특정 신경계의 한 예로 모노아민성 신경계를 선택하여 납중독의 지표로 모노아민성 신경계의 효소인 MAO (mono-amine oxidase)의활성을 측정하였으며, 비특정 조직의 지표로 Na+K+-ATPase의 활성을 측정하였다. Wistar계의 흰쥐에서 태어난 새끼들에게 출생직후부터 전실험기간을 통해 0.05% 혹은 0.2% 초산납 (PbAc2)용액을 식수로 공급하여 납중독을 유발시켰다. 생후 2, 4, 6 및 8주된 새끼쥐의 MAO 및 Na+K+-ATPase활성을 대뇌, 간뇌, 중뇌, 뇌교-연수 및 다섯부위에서 각기 측정하였다.

Purpose : This report is the result f retrospective analysis for children who received prophylactic cranial irradiation combined with intrathecal chemotherapy. Materials and Methods : Ninety children with ALL who had got bone marrow remission after induction chemotherapy received PCI. All but 3 children were treated with a dose of 1800 cGy as a standard regimen. While the PCI was given, all patients received intrathecal chemotherapy. Results : Nine of 90 patients experienced CNS relapse during the duration of follow-up ranged from 36 to 96 months (median 60 months). Three children experienced BM relapse prior to CNS relapse. Therefore, CNS relapse rate as the first adverse event was $6.7\%$. Median time interval of CNS relapse was 16 months from the first day of hematologic complete remission. Eighty-nine percent of patients who had CNS relapse were associated with hematologic relapse. and $78\%$ of CNS relpase occurred during maintenance chemotherapy (on-therapy relapse). The CNS RFS at 2 and 5 years are $68\%$ and $42\%$, respectively with median of 43 months. The Prognostic factors affecting CNS RFS are initial WBC count (cut-off point of 50,000/ul), FAB subtype and CALGB risk criteria. The DFS at 2 and 5 years are 61 and $39\%$, respectively with median of 34 months. The prognostic factors affecting DFS are initial WBC count (cut-off point of 50,000/ul), FAB subtype, POG and CALGB risk criteria. Conclusions : In our study, $6.7\%$ of CNS relapse rate as a first adverse event was comparable with other studies. Various risk criteria was based on age at diagnosis and initial WBC count such as POG and CALGB criteria, had prognostic significance for CNS RFS and DFS. Prospective randomized trial according to prognostic subgroup based on risk criteria and systematic study about neuropsychologic function for long term survivors, are essential to determine the most effective and least toxic form of CNS prophylaxis.

Purpose: This study was to evaluate the effects of foot reflexology massage on the central pain, fatigue and sleep in stroke patients. Methods: The study utilized a non-equivalent control group pretest and posttest design. Subjects were contacted at the oriental medicine ward of D hospital in B city for strokes. The subjects were 25 in the experimental group and 23 in the control group. Collected data were analyzed central pain, fatigue and the change of sleep between pre and post foot reflexology massage using a t-test, $x^2-test$, Fisher's exact test by SPSS 12.0 Win program. Results: There were significant decrease in the central pain, fatigue and change of sleep between pre and post foot reflexology massage. Conclusion: The results proved that foot reflexology massage was an effective stroke patients to decrease in the central pain, fatigue and change of sleep. Therefore, this foot reflexology massage should be effective as a stroke patients.

Primary central nervous system T-cell lymphoma (PCNSTL) is an extremely rare type of brain tumor. There are only few reports on the imaging findings of patients with PCNSTL. Herein, we report the imaging findings of a patient with peripheral T-cell lymphoma-not otherwise specified that presented with numerous small nodular and patchy strongly enhancing lesions on MRI.

The purpose of this study was to investigate the effect of the increased sympathetic outflow on the changes of muscle tone and central nervous system excitability in the chronic stroke patients. This study was conducted from October 12th 2009 to December 4th 2009. 30 patients with chronic hemiplegia for at least 6 months were participated. Before and during the mental arithmetic, static handgrip and post-handgrip ischemia tasks, the central nervous system action potentials and global synkinesis level were compared. The central nerve action potentials were measured with H/Mmax ratio and V/Mmax ratio. To obtain global synkinesis level, surface electromyography data were digitized, processed to root mean square. In our study, The global synkinesis level during knee flexion and extension was decreased in the mental arithmetic and in the post-handgrip ischemia task(p<.05) but not in the grip task. Also, V/Mmax ratio was decreased all in the three task(p<.05). In conclusion, we know that the central nervous system excitability and the muscle tone in chronic hemiplegic patients were decreased by the increased sympathetic outflow.

From 1982 to 1991, sixteen Patients with primary non-Hodgkin's lymphoma of the central nervous system(CNS) were seen at Kyung Hee University Hospital. The most common subtypes were large, noncleaved cell lymphoma and immunoblastic lymphoma of B cells. Lesions most commonly involved were the parietal lobes and/or deep nuclei. Positive cerebrospinal fluid cytology was rare at initial presentation. Sixteen patients were treated with surgical biopsy or resection followed by whole brain radiotherapy at a median dose of 40 Gy(range=30-50 Gy) with variable boost doses. Of 16 patients who underwent surgery and postoperative radiotherapy, fourteen patients died between 2 and 49 months following treatment, and two are alive with no evidence of disease at 8 and 22 months. The 1-and 2-year survival rates were 55.6$ \% $ and 34.7$ \% $, respectively with 12 months of median survival. Patterns of failure were analyzed in eleven patients of total 16 patients. Failure at the original site of involvement was uncommon after radiotherapy treatment. In contrast, failure in the brain at sites other than those originally invovled was common in spite of the use of whole brain irradiation. Failure occurred in the brain 11/16(68.7$ \% $), in spinal axis 4/16(25.0$ \% $). The age, sex, location of involvement within CNS, numbers of lesion, or radiation dose did not influence on survival. The authors conclude that Primary CNS lymphoma is a locally aggressive disease that is poorly controlled with conventional radiation therapy. The limitation of current therapy for this disease are discussed, and certain promising modality should be made in regarding the management of future patients with this disease.
