‘Duplication of the middle cerebral artery’ is a rere vascular anomaly of the brain. The authors experienced a case of duplication of the middle cerebral artery in a patient with a posterior communicating artery aneurysm. It was demonstrated by angiography and confirmed at surgery. The neck of aneurysm was succesfully clipped. Postoperative course was uneventful.

Objective:The purpose of this study is to determine whether human dendritic cells(DCs) pulsed with glioma apoptotic bodies(GABs) can induce tumor-specific T lymphocytes having cytotoxicities to allogeneic glioma cells matched or mismatched at class I human leukocyte antigen(HLA) loci. Methods:DCs were generated from peripheral blood mononuclear cells(PBMCs) of HLA-A2 positive healthy donors cultured in the presence of granulocyte macrophage-colony stimulating factor and interleukin(IL)-4. GABs from HLAA2 positive T98G glioblastoma cells following actinomycin D treatment were pulsed to DCs. CD8+ T lymphocytes isolated from PBMCs of the same donors were cultured in media containing IL-2 and were stimulated by GAB-pulsed DCs three times at weekly interval. Then cytolytic activities of these cytotoxic CD8+ T cells against HLA-A2 positive T98G and U87 glioblastoma cells, and HLA-A2 negative A172 glioblastoma cells were determined by a standard 4hr [51Cr]-release assay. Results:The average percentages of T98G , U87 and A172 cell lysis were 43.7%, 45.6% and 5.1% compared with 3.6% of controls at an effector to target cell ratio of 40:1 respectively. The cytotoxic T lymphocytes(CTLs) primed with HLAA2 positive T98G GAB-pulsed DCs had cytotoxicity to HLA-A2 positive T98G and U87 glioma cells but not to HLAA2 negative A172 cells(p<0.01). Conclusion:This study showed that tumor-specific CTLs generated by stimulations with GAB-pulsed DCs had cytotoxicity to the glioma cells in a HLA-restricted manner. This result suggests the feasibility of the use of HLA-matched allogeneic glioma cells as a source of antigens for patients not eligible for surgery in the DC-based immunotherapy.
