RESUMO
Personal identification is an essential subject in forensic practice. With skeletonized remains, an anthropological examination is performed for personal identification. Here we describe the positive identification of skeletonized human remains from the serial numbers of implanted metallic plate and screws.

We present here a case of sudden death resulting from the rupture of an aneurysm of the splenic artery. From the histopathological findings, we concluded that the formation of the splenic aneurysm was associated with the fibromuscular dysplasia.

In order to investigate the malignant phenotype of cyclooxygenase (COX)-2 overexpressing cancer cells, a human epidermoid KB carcinoma cell line minimally expressing COX-2 protein was transfected with human COX-2 cDNA. In this study, we used a COX-2 transfected clone KB/COX-2 and a neomycin-transfected clone KB/neo as the control. When we examined the susceptibility to anticancer agents, there was no difference between these two clones in vincristine, bleomycin and 5-fluorouracil, although KB/COX-2 showed a 2.5-fold resistance to cisplatin (CDDP) as compared with KB/neo. The IC50 for CDDP was 4.3 microM in KB/COX-2 and 1.7 microM in KB/neo. Treatment with small interfering RNA (siRNA) mediated the inhibition of COX-2 significantly increasing the level of susceptibility to CDDP in COX-2 siRNA as compared to that of the control siRNA. The expression of MRP1 and MRP2 was stronger in KB/COX-2 than in KB/neo by Western blot analysis. In addition, apoptosis induction by CDDP was at a lower level in KB/COX-2 (31%) than in KB/neo (38%). These results suggested that the overexpression of COX-2 increases the intracellular production of MRP1 and MRP2 and causes drug resistance to CDDP.
