Brunner's gland adenoma(or Brunneroma) is clinically relevant tumor-like lesion of the duodenum which is composed of submucosal Brunner's gland tissue. Since the first case by autopsy was described by Cruveihier in l935, there have been less than 190 reports in the world literature, Brunner's gland adenoma is an extremely rare entity that accounts for only 10.6% of benign duodenal tumors, which are themselves relatively rare representing 0.008% of all surgical and autopsy specimens. The clinical manifestation of this tumor are non-specific gastrointestinal complaints, such as bloating or epigastric pain, and tumor often gives rise to melena or obstruction, It is postulated that this tumor are hamartomas rather than true neoplasm. However, they undergo rarely malignant transformation. We report on a case of a large pedunculated Brunner's gland adenoma, which was successfully polypectomized.

Angiogenesis plays a fundamental role in development of circulation system, reorganization of reproductive system, wound healing. Pathological angiogenesis is deeply involved in a variety of diseases, particularly solid tumor growth and metastasis. However, it is not easy to study the mechanism of angiogenesis because endothelial cells proceed complex differentiation by interaction with extracellular matrix proteins and growth factors. However, human umbilical vein endothelial cells (HUVEC) form polygonal networks of capillary-like tubes in 3D Matrigel cultures. Differentiation of endothelial cells will be observed accurately by application of videomicroscopy. Thrombospondin-1 is secreted by a wide variety of cells including endothelial cells and is incorporated into their matrix. Thrombospondin-1 can modulate differentiation of endothelial cells by increasing cell-cell interactions as well as cell-substrate interactions. The current study was undertaken to determine which mechanism is involved in inhibition of angiogenesis by Thrombospondin-1. They was secreted from HUVEC during the process of angiogenesis in 3D Matrigel culture. When applied to endothelial cells attachment to the surface of Matrigel was not decreased, but spreading was decreased. In addition, bigger clusters was formed by enhancement of cell to cell binding by Thrombospondin-1. They inhibit cord and tube formation of HUVEC by inhibition of migration. These results suggest that Thrombospondin-1 inhibits angiogenesis by blocking differentiation of endothelial cells to motile phenotype in 3D Matrigel culture.

We report the results of the clinical and histologic and radiologic findings of the 17 patients who visited our hospital for the removal of the breast implants. Their mean ages were 45.9 and they visited our hospital 11.4 years after their operation of the breast implantation. In the 8 cases of the 17 patients, the contractures were seen and masses were palpated in the 4 cases. We also could find 1 case of the infection and 1 case of the abscess. There were the cases of the granuloma, siliconoma, calcification too. We find the radiologic examination before the removal of the implants in the 11 cases and could find the finding of rupture at the 9 cases (14 implants) but we confirmed that the number of the ruptured implants were 7 postoperatively. We reinserted new implants in the 12 cases and used saline filled textured implants. the number of the patients who want to remove the silicone gel implants is increasing with the reports of the doubt on the safety of the silicone gel. But there were on clear evidences of harmful effects of the silicone gel at now. We have to study more and need more experiences to used the more exact information to the patients.

We report a case of acute graft-versus-host disease, which developed after bone marrow transplantation because of acute myelocytic leukemia in a 39-year old male, The pruritic, erythematous maculopapular eruptions began to developed on the perioral regions, and spreaded the face, the oral mucosa, both hands, and buttocks at the twenty fourth day after bone marrow transplanta.tion. The eruptions were confluent to form erythematous patches. Iistopathological findings show parakeratosis, lymphoid cell exocytosis, and papillary edema, lymphohistiocytic infiltration, and melanophage in the upper dermis, and basal vacuolation. He was treated systemically by methylprednisolone, and antilymphocytic globulin, and tapically by emollients and steroids.
