Introduction : Despite the advanced neurosurgical techniques and various multimodal therapeutic approach have been developed for malignant gliomas, these can not save the patients from the tumors due to infiltrating behavior of glioma cells. Here the authors investigated the possibility of treatment for the malignant gliomas with neural stem cell(HB1.F3) transduced with suicidal gene using the tropism of stem cells. Materials and Methods : E.coli cytosine deaminase(CD) is an enzyme that catalyzes the conversion of noncytotoxic 5- FC to the cytotoxic and radiosensitizing drug 5-FU. Cytotoxic 5-FU and its toxic metabolites can readily diffuse into surrounding tumor cells giving CD. HB1.F3 were transduced with retroviral vectors expressing the E.coli CD. Rats were implanted with U373MG, U251MG human glioblastoma(hGM) cell line and F3/CD were injected directly into the tumor mass 6 days later. The rats with tumors were injected IP 5-FC or saline daily for 7 days since 6 days after implantation of tumors. Results : HB1.F3 which were injected into the contralateral hemisphere to the tumor implantation site migrated through the corpus callosum to the tumor cells 3 days after hGM transplantation . The growth inhibition of 5-FU treated cells in comparison to untreated controls was remarkable in vitro. The tumor mass in the rats with transplantation of F3/CD were reduced markedly in size comparing to that with F3 after injection of 5-FC . Conclusions : The human neural stem cells can trace to the glioma cells in the rat brain. 5-FC systemic treatment with direct transplantation of F3/CD reduces tumor size. Our data indicates that suicide gene therapy using neural stem cells would be promising as a new therapeutic approach for malignant glioma.

Objectives : The present study was performed to verify the validity and value of 4th revision of Schizophrenia Quality of Life Scale (SQLS-R4) as an assessment tool in a Korean-language version (SQLS-R4K). Methods : The subjects for present study were 174 patients with a diagnosis of schizophrenia as defined by DSM-IV. The SQLS-R4K was administered together with self-report Korean version of World Health Organization Quality of Life-Brief Scale(WHOQOL-BREF) to assess validity. A subset of respondents also completed the SQLS-R4K for a second time to assess test-retest reliability. To evaluate the relationship SQLS-R4K and clinical characteristics, psychotic symptoms and general functioning were evaluated using the Positive and Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning Scale (GAF) score respectively. Results : All the scales of SQLS-R4K showed good internal consistency reliability. The correlations of items with their scale total revealed that all items were significantly correlated with their own scale score. In test-retest reliability, paired t-tests indicated that responses did not alter significantly between the two assessment. There was moderate correlation between WHOQOL-BREF sub-scores and SQLS-R4K score total. Also relevant correlations between PANSS, current GAF and SQLS-R4K were proved. Conclusion : From the results of the testing the reliability and validity of the SQLS-R4K, it is concluded that the SQLS-R4K is a simple and reliable scale for measuring quality of life in schizophrenic patients.
