 Abstract
 PDF
- Odontogenic keratocysts are benign intraosseous tumors of odontogenic origin that occur most commonly in the jaw. In particular, they have a predilection for the angle and ascending ramus of the mandible. In contrast, odontogenic keratocysts arising in the maxillary sinus are relatively rare. Two such cases are reported herein. In addition, the English literature that concerns odontogenic keratocysts of the maxillary sinus is reviewed.

- The c-erbB-2 oncogene, which is a new human proto-oncogene similar to EGFR structurally, generates a glycoprotein of tyrosine kinase family with a molecular weight of 185,000 To evaluate the prognostic significance of c-erbB-2 oncogene expression in colorectal carcinoma, We analysed 73 colorectal carcinomas in paraffin sections immunohistochemically, using the monoclonal antibody specific for the c-erbB-2 oncogene product and correlated with clinicopathological data. The results were as follows 1) The immunoreactivity for c-erbB-2 oncogene was localized to cell membrane of the tumor cells and occasionally observed within the cytoplasm. 2) The positivity of c-erbB-2 oncogene expression was 71.2%(52/73) of the colorectal carcinomas overall. According to the histological types, the positivity of c-erbB-2 oncogene in adenocarcinoma(77.4%) was higher than that in mucinous carcinoma(36.4%)(p<0.05). 3) Expression of c-erbB-2 oncogene was significantly correlated with lymph node metastasis or distant metastasis(p=0.0117), Dukes stage(p=0.0432), and TNM classification(p=0.0102).
These results suggest that c-erbB-2 oncogene expression may be used as a prognostic factor of colorectal carcinoma because of its correlation with other clinicopathological prognostic factors.

Abstract
PDF
- To fine out the changes of DNA ploidy and cellular proliferation activity during carcinogenesis and evaluate correlation between flow cytometrically determined S-phase fraction and proportion of proliferation cell nuclear antigen(PCNA, PC10) immunoreactive cells, the authors studied on malignant fibrous histocytoma induced by intra-articular injection of 9, 10-dimethy1-1, 2-benzanthracene(DMBA) in the rats. Forty Wistar rats were used. The results obtained were as follows. 1) Firstly, tumors were palpated 5 weeks after the last injection of DMBA and formed in 27 rats at sacrificed. Histologically, these lesions showed storiform, indicative of malignant fibrous histiocytoma. 2) Three cases of DNA aneuploidy were observed at 4 and 5 months after the last injection of DBMA and one of them, which was DNA diploidy at main mass, was found at daughter mass. 3) Flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells in malignant fibrous histiocytoma induced by DMBA were much higher than in control groups and slightly increased according to sequential changes after formation of mass. The comparison of flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells showed significant correlation(r=0.6092, p<0.001). Above results strongly suggest that ploidy pattern may evolve into aneuploid type during the development of tumor and proliferation activity increases during the carcinogenesis.
