For more than 80% of body weight is transmitted through the anterior and middle column, the interbody gap produced by operative reduction of spondylolisthesis is potential risk factor for redisplacement, implant failure, pseudoarthrosis and kyphosis. In biomechanical aspect, augmentation of the anterior column support by interbody fusion is desirable to prevent above problems in surgical treatment of spondylolisthesis. Recently, circumferential fusion is recommended in high-grade spondylolisthesis (grade III, IV, or V ), but there is some controversy about additional interbody fusion in posterior instrumentation for low-grade spondylolisthesis (grade I or II ). So, the purpose of this retrospective study was to compare the segmental sagittal angle in 35 patients of low-grade spondylolisthesis who was performed posterior instrumentation with or without posterial lumbar interbody fusion (PLIF) and to find out the risk factors of the loss of segmental sagittal angle in cases of posterior instrumentation without posterial lumbar interbody fusion (PLIF).

OBJECTIVES: This study was designed to verify neuro-developmental hypothesis of schizophrenia and mood disorder. METHOD: We performed Brain Magnetic Resonance Imaging study in 34 schizophrenic patients, 18 mood disorder patients and 22 controls and compared the incidence and the size of carum septi pellucidi (CSP). RESULTS: The incidences of CSP in schizophrenia, mood disorder and controls were 61%, 61%, and 41%, respectively. The incidences of large CSP, defined as largest diameter larger than 3mm in T1-weighted image, were 24% in schizophrenic patients, 11% in mood disorder patients, and 5% in controls. But they didn't show statistically significant differences. CONCLUSION: We could find the tendency that the incidence of CSP was high as following order; schizophrenia, mood disorder, controls. But it was not statistically significant difference. To verify neuro-developmental hypothesis, we need larger pool of patients and better study design.

OBJECTIVES: The purpose of this study is to determine the amount of burden placed on the caregivers of patient diagnosed as dementia and depression. The study is intended 1) to compare depression and anxiety levels of caregivers with the degree of their burden and 2) to analyze and determine the clinical factors that contributed to such levels of depression and anxiety. METHODS: 93 individuals with dementia, suspected dementia, and depression were selected between February 2001 and April 2001. In order to determine the patients decreased cognitive function and psychopathology MMSE-K and NPI were used. In addition, the burden scale recently developed from Zarit, HARS, HDRS were used on 58 caregivers. RESULTS: The MMSE-K figure form in the demented group was significantly lower than that of the non-demented group, 15.65 and 25.55 respectively. As for the NPI figures, the demented group posted higher numbers compared to the non-demented group. Among the individuals in the demented group, apathy, aberrant motor behavior, and night-time behavior showed the highest figures. On the caregiver's burden point, the demented group showed higher scores compared to the non-demented group with 76.62 and 58.30 respectively. The caregiver's burden point compared to the HDRS and HARS figures provided an evidence that there is a signigicant relationship between the groups. CONCLUSIONS: The caregiver's burden point is found to be more affected by the demented patient's progressive phase of psychopathology than conditions due totheir decreased cognitive functions. There is a probability that an increase in the caregivers burden is likely to contribute to an increase in the caregiver's depression and anxiety.

OBJECTIVE: Arsenic trioxide (As2O3) is known to have potent anti-vascular activity and significantly suppress solid tumor growth. The present study was conducted to investigate the vascular shutdown effects of a novel arsenic compound, tetraasrsenic oxide (As4O6), in comparison with As2O3 using cervical cancer animal model. METHODS: Mice tumor challenge model was used C57BL/6 mice transplanted with TC-1 cells. After the growth of tumors was reached up 200~250 mm3, mice were divided into 3 groups randomly for control and treatment of either As2O3 or As4O6. As2O3 and As4O6 was treated by i.p. injection. The tumor size was caliperated in twice for weeks and anti-vascular effect were assessed by Evans blue extraction assay and Hoechst 33342 staining. In tumor tissue, histopathological feaure was obserevd by hematoxylin and eosin (H&E) staining. RESULTS: In mice treated with either As2O3 and As4O6 (i.p.), both of As2O3 and As4O6 was significantly suppressed the tumor growth compared with control group. Moreover, effect of As4O6 is more pronounced. These tumor growth inhibition is led to the massive necrosis and vacular shutdown in tumor tissue. CONCLUSION: This study suggests that As4O6 may have potential anticancer activity via vascular shutdown in C57BL/6 mice transplanted with TC-1 cells.

OBJECTIVE: The aim of this study is to porve the hypothesis that the etiological neuropathological defects of the Tourette's Disorder (TD) lie in a network linking the basal ganglia and the cerebrum, not at a particular single brain region. In this study, the volumes of 10 cerebral and cerebellar regions and their symmetries were measured in normal boys and TD boys by brain magnetic resonance imaging. METHODS: Brain magnetic resonance images were obtained prospectively, controlled for confounding variables(handedness, drug-effect, effect of comorbid psychiatric disorders), in 19 boys with TD and 17 age-matched normal control boys. The frontal, parietal, temporal, and the occipital lobes and the cerebellum were defined using the semi-automated Talairach atlas-based parcellation method. RESULTS: Although the smaller brain volume was taken into account, boys with TD had larger frontal lobes and reduced normal asymmetry (right>left). There were no significant differences in the regions of interest of the parietal, temporal, or the occipital lobes or the cerebellum. CONCLUSION: These findings suggest that boys with TD may have neuropathological involvement in the frontal lobe. And this findings also support the hypothesis of abnormality in Cortical-Striatal-Thalamo-Cortical (CSTC) circuitry as an etiological factors of the Tourette's Disorder.

Neuropathological deficits are an etiological factor in Tourette syndrome (TS), and implicate a network linking the basal ganglia and the cerebrum, not a particular single brain region. In this study, the volumes of 20 cerebral and cerebellar regions and their symmetries were measured in normal boys and TS boys by brain magnetic resonance imaging. Brain magnetic resonance images were obtained prospectively in 19 boys with TS and 17 age-matched normal control boys. Cerebral and cerebellar regions were segmented to gray and white fractions using algorithm for semi-automated fuzzy tissue segmentation. The frontal, parietal, temporal, and the occipital lobes and the cerebellum were defined using the semiautomated Talairach atlas-based parcellation method. Boys with TS had smaller total brain volumes than control subjects. In the gray matter, although the smaller brain volume was taken into account, TS boys had a smaller right frontal lobe and a larger left frontal lobe and increased normal asymmetry (left>right). In addition, TS boys had more frontal lobe white matter. There were no significant differences in regions of interest of the parietal, temporal, or the occipital lobes or the cerebellum. These findings suggest that boys with TS may have neuropathological abnormalities in the gray and the white matter of the frontal lobe.
