A histopathologic study including iramunohistochemical stains was made in 30 patients who were presented with gastrointestinal lymphoma. The occurrence was 13 in the stomach, 8 in the ileocecum, 7 in the small intestine and 2 in the colon. The disease more frequently affected males than females and the average ages were 53 years in the patients of gastric lymphoma and 44 years in the patients of intestinal lymphoma. Gastric lymphomas were usually presented with a single lesion, and the antrum and/or body were the most common sites. But intestinal lymphomas were presented with a single or multiple lesion, and the ileocecum was the most common site. The most common gross type of gastrointestinal lymphomas was the ulceroinfiltrating type and most are of the diffuse large noncleaved cell type of B-cell lymphoma, histologically. There were 2 cases of T-cell lymphoma presented in the intestine as the superficially ulcerative gross pattern and diffuse immunoblastic cell type. The distinct MALToma was seen in only one case of stomach but the feature was partially remained in each two cases of stomach and intestine. Their coexistent findings may suggest that diffuse large of immunoblastic component arises through blastic transformation of the low-grade M ALToma component.

PURPOSE: To investigate the efficacy of percutaneous embolization of hypervascular VX-2 carcinoma in the retroorbital area of the rabbits using Histoacrylic Blue(N-butyl 2-cyanoacrylate, NBCA) and to establish as an experimental model. MATERIALS AND METHODS: Retroorbital VX-2 carcinoma was made in 10 rabbits by injection of carcioma cells. At 2 and 4 weeks following the tumor cell injection, carotid angiography was performed before and after percutaneous embolization using 50% NBCA diluted with Lipiodol. Doppler ultrasonography was also performed to evaluate the vascularity of the mass. Light microscopic examination was used to evaluate the effect of embolization on the tumor mass. RESULTS: Angiography following percutaneous embolization showed filling of embolic materials in the tumor beds. Ultrasonographic findings showed tumor necrosis and increased Doppler signal in the tumor. Histopathological examinations showed extensive necrosis of tumor cells with remaining viable cells surrounding the capillaries. There were no NBCA emboli in arterioles and capillaries of tumor beds in multiple sections. CONCLUSION: Since 50% diluted NBCA used as percutaneous embolus into the retroorbital VX-2 carcinoma dose not get into small blood vessels of tumor beds. using NBCA in lower concentration in the hypervascular tumor would be the next step to figure out its usefulness. This study also serves as an experimental model of percutaneous embolization of hypervascular tumor.

Bond strength depends on characteristics of bonding surface and restorative technique. The majority of studies dealing with dentin bond strength were carried out on flat bonding surface, therefore, difference of bond strength between axial wall and pulpal wall is not clear yet. This study evaluated bonding difference between cavity walls in class I composite resin restoration with different filling techniques. Twenty extracted caries-free human third molars were used. Cavities were prepared in 6 x 4 x 3 mm box-type and divided into four groups according to filling technique and bonding surface: Group I; bulk filling - pulpal wall, Group II; bulk filling - axial wall, Group III; incremental filling - pulpal wall, Group IV; incremental filling - axial wall. Cavities were filled with Filtek Z250(R)(3M/ESPE., USA) and Clearfill SE bond(R)(Kuraray, Japan). After 24 hour-storage in 37degrees C water, the resin bonded teeth were sectioned bucco-lingualy at the center of cavity. Specimens were vertically sectioned into 1.0 x 1.0 mm thick serial sticks perpendicular to the bond surface using a low-speed diamond saw (Accutom 50, Struers, Copenhagen, Denmark) under water cooling. The trimmed specimens were then attached to the testing device and in turn, was placed in a universal testing machine (EZ test, Shimadzu Co., Kyoto, Japan) for micro-tensile testing at a cross-head speed of 1 mm/min. The results obtained were statistically analyzed using 2-way ANOVA and t-test at a significance level of 95%. The results were as follows: 1. There was no significant difference between bulk filling and incremental filling. 2. There was no significant difference between pulpal wall and axial wall, either. Within the limit of this study, it was concluded that microtensile bond strength was not affected by the filling technique and the site of cavity walls.
