Two cases of acquired absence of forearm bone secondary to compound comminuted fractures were treated by reconstructive surgery, which consist of surgical construction of one-bone forearm. The results of treatment were referred and the review of the literature was done concerning about surgical reconstruction of one-bone forearm.

Papillary carcinoma of the thyroid is a well differentiated neoplasm and usually has a good prognosis. However, a subset of morphologically distinct papillary carcinoma has bad prognoses. The tall cell variant of papillary carcinoma (TCPC), characterized by tall columnar cells with a height at least twice the width, is the one of these. In order to differentiate TCPC from usual papillary carcinoma (UPC) in terms of prognosis, we performed immunohistochemical studies for the expression of p53, bcl-2 and Leu-M1 proteins in 25 cases of TCPC, 26 cases of UPC and 14 cases of poorly differentiated, solid type papillary carcinoma (SPC) with an analysis of clinical parameters. The nuclear expression of p53 was noted in one case each of UPC and TCPC. The cytoplasmic p53 expression of TCPC, UPC, and SPC was observed in 17/25 cases (68%), 14/26 cases (54%), 3/14 cases (21%), respectively. bcl-2 expression was 19/25 cases (76%), 18/26 cases (69%), 5/14 cases (36%), and that of Leu-M1 was 21/25 cases (84%), 18/26 cases (69%), 4/14 cases(29%), respectively. There were no statistical significance in the expression of those immunoproteins among these three groups (p>0.05). The p53 protein was consistently expressed in the cytoplasm rather than nucleus in this study and was very well correlated to bcl-2 positivity (p<0.01). There were no statistical significance in any clinical parameters examined among these three groups (p>0.05). In conclusion, TCPC can not be separated from UPC as a distinct entity in this study and the cytoplasmic expression of p53 protein provides another mechanism of p53 inactivation in tumorigenesis of the thyroid papillary carcinoma, possibly by bcl-2 related mechanism.

Inflammatory pseudotumor of the urinary bladder is an unusual, benign mesenchymal proliferative lesion of the submucosal stroma easily mistaken for a malignant neoplasm clinically and histologically. We present a case and describe the clinical presentation and radiologic, histologic, histochemical, immunohistochemical, and ultrastructural findings. A 23-year old patient presented with sudden onset of gross painless hematuria for 3 months. There was no previous instrumentation or surgery involving the genitourinary tract. Cystoscopy revealed a large polypoid and ulcerated bladder mass. The lesion consisted of plump spindle shaped, fibroblast-like cells embedded in a myxoid stroma. Mitotic figures were negligible and the lesion showed encroachment on the superficial muscle bundles. The spindle cells were immunoreactive for vimentin and muscle specific actin. Immunohistochemical and ultrastructural findings revealed the fibroblastic-myofibroblastic nature of this lesion. Complete surgical excision by partial cystectomy was successful in eradicating the lesion. The findings are described with a discussion of the pathogenesis and review of the literature.

5 bed sand filter, applying biological oxidation, was designed and studied on the treatment of water works. Never using any coagulant agent (drugs), which may cause water pollution in pre-treatment of head water, the author attempt a high rate filtration by the microorganism (nitrofication bacteria) end plant which populate in multi layer sand beds. The result are as follows ; In order to evaluate the oxygen effect on filtration, oxygen was injected in aeration tank attached to each filter tank while filtration, and NH3 was tested as a representative ingredient. It was found out that the aeration method was more effective, with over 33% of NH3 removal capacity, than the anerobic and this 5 bed filter showed double removal capacity of NH3 by comparing with conventional sand bed (2 stage bed). According to the examination of two kind of head water, pre-treated with coagulant agent and activated carben, the filtration capacity was affected by the polluted condition of head water, resulting that lower value of pollution and slower velocity of filtration showed more efficiency of NH3 removal. In this experiment NH3 content tested in treated water had a fairly good correlation with others.

Carcinosarcoma of the female genital tract, also called malignant mixed mullerian tumor (MMMT), is a rare and relatively aggressive tumor with various homologous and heterologous components. There have been various studies to find prognostic factors and to investigate the histogenesis, including tissue culture, electron microscopy, and immunohistochemical studies. We investigated carcinomatous, sarcomatous, and transitional areas of 6 cases of carcinosarcoma of the uterus and ovary by using epithelial and mesenchymal markers. Immunohistochemical profiles of the transitional areas were significantly different from those of carcinomatous and sarcomatous areas. Immunoreactivities for cytokeratin and epithelial membrane antigen (50% and 22.2%) were weaker than those of carcinomatous areas (95.2% and 100%), but stronger than those of sarcomatous areas (11.1% and 5.6%)(p<0.01). In transitional areas, vimentin, smooth muscle actin and S-100 protein were more strongly expressed than in carcinomatous areas, but more weakly expressed than in sarcomatous areas (p<0.01, p<0.01, and p=0.018, respectively). Myoglobin was entirely negative in carcinomatous areas and immunoreactive in minor portions of transitional and sarcomatous areas (22.2% and 16.7%, respectively). These results suggest that the transitional areas are between the carcinomatous and sarcomatous nature in differentiation, further supporting that the carcinosarcomas of the female genital tract may arise, through metaplastic change, from a type of carcinoma.

The lack of sufficient oral mucosa available for intra-oral reconstruction has been dealt with by the use of skin or oral mucosa grafts harvested from donor sites but grafts requires more than one surgical procedures and could cause donor site morbidity. Many investigators have attempted to increase available soft tissue by tissue engineered skin or oral mucosa replacements for clinical applications. But, reconstructed mucosa by several methods have low physical properties such as rolling and contraction. The aims of this study were to develope an in vitro experimental model that maintains an epithelial-mesenchymal interaction by organotypic raft culture, and to characterize biologic properties of three-dimensionally cultured oral mucosa embedded with Polydioxanone mesh by histological and immunohistochemical analysis. The results were as follows; 1. Oral mucosa reconstructed by three-dimensional organotypic culture revealed similar morphologic characteristics to equvalent normal oral mucosa in the point that they show stratification and differentiation. 2. The expression of cytokeratin 10/13 and involucrin in the cultured tissue showed the same pattern with normal oral mucosa suggesting that organotypic co-culture condition is able to induce cellular differentiation. 3. After insertion of polydioxanone mesh, increased tensile strength were observed. These results suggest that three-dimensional organotypic co-culture of the oral mucosa cell lines with the dermal equvalent consisting type I collagen and fibroblasts reproduce the morphologic and immunohistochemical characteristics similar to those in vivo condition. And increased physical properties by use of polydioxanone mesh will helpful for clinical applications.
