Plexiform schwannoma is a rare benign tumor arising from the peripheral nerve sheath and characterized by a multinodular and plexiform growth pattern. This tumor usually arises sporadically. In rare cases, plexiform schwannomas have been associated with neurofibromatosis type 2. Plexiform schwannoma should be differentiated from plexiform neurofibroma, because the latter is pathognomonic tumor of neurofibromatosis type 1 and has a potential of malignant transformation. We report a case of multiple plexiform schwannomas associated with bilateral acoustic neuromas and meningioma.

14-3-3 proteins are cytoplasmic proteins of about 29 kDa and have a minimum of seven isoforms. This protein is important in signal transduction with the ability of binding with phosphoserine of many signalling proteins. We expressed 14-3-3 protein tagged with 6 histidine residues in E. coli and purified the protein by nickel affinity chromatography. Using this purified protein as an antigen, we made rabbit antisera and mouse monoclonal antibodies to 14-3-3 zeta isoform. We subcloned cDNA of 14-3-3 zeta isoform derived from HeLa cell lamda gt 11 library into an E. coli expression vector which is designed to express heterologous protein with N- terminal 6 hidtidine tag. BALB/c mice were immunized with purified 14-3-3 protein and the hybridoma clones which produce monoclonal antibodies angainst 14-3-3 protein were selected. These monoclonal antibodies reacted with the recombinant protein expressed in E. coli as well as the 29-kDa native protein in various cell lines. However, they did not immunoprecipitate 14-3-3 protein. The monoclonal antibodies produced in this study can be valuable tools for the identification of the 14-3-3 in signal transduction study.

Pseudoaneurysm due to chronic pancreatitis is uncommon, but it can cause recurrent and massive hemorrhage. Because of high morbidity and mortality associated with the pseudoaneurysm, early detection and treatment is essential. Surgical ligation or resection of the aneurysm has a high mortality and therefore, transcatheter embolization is preferably carried out. We report a case in which gastroduodenal artery pseudoaneurysm caused by chronic pancreatitis was successfully treated by transcatheter embolization using Gelfoam and Gianturco spring coils.

This study was undertaken to know the extent of apoptosis, expression of bcl-2 and proliferating cell nuclear antigen (PCNA) in uterine cervical intraepithelial neoplasia (CIN; 15 cases) and invasive carcinoma (27 cases) and to evaluate them as a prognostic marker. Apoptosis was analysed by using the in situ apoptosis detection kit and bcl-2 and PCNA were detected by the immunohistochemical method. The results were as follows: Apoptotic indices (AI) in the invasive carcinoma (mean: 4.3) were 10-times higher than that in the CIN (mean: 0.43). Bcl-2 was expressed 60% of the cases in the dysplastic cells of the CIN II and CIN III, 33.3% of cases in the invasive carcinoma and not expressed in the CIN I except basal cells. The expression of the PCNA was increased by the grades of CIN and was strong in invasive carcinoma. The mean survival time of the patient with invasive carcinoma was significantly decreased in the higher AI index (above 4.3) than in the lower AI index (below 4.3). There was no significant correlation between the extent of apoptosis and the expression of bcl-2. According to the above results, AI are able to be used as an independent prognostic marker in the invasive cervical carcinoma, and bcl-2 and PCNA have an important role in the tumorigenesis of uterine cervical carcinoma.
