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.

To determine the perinatal mortality and morbidity of fetuses with absent end-diastolic velocities (AEDV) of the umbilical artery in severe pre-eclampsia and eclampsia, the outcome of 5 fetuses with AEDV was compared with that of 35 fetuses with positive end-diastolic velocities (PEDV). The study population comprised 38 cases of severe pre-eclampsia and 2 cases of eclampsia with structurally normal singletons, who had had umbilical artery Doppler velocimetry weekly from admission to delivery. The Doppler velocimetry result was not used for the clinical management. Perinatal death and neonatal morbidity from both groups were further examined in gestational age category to control the influence of preterm births. The incidence of AEDV of the umbilical artery Doppler velocimetry in severe pre-eclampsia and eclampsia was 12.5% (5/40). The AEDV group had a significantly higher incidence than the PEDV group in terms of ceasarean section due to fetal distress (60% : 17%), Apgar score < 7 at 5 minutes (60% : 14%), perinatal death (25% : 0%) and assisted mechanical ventilation (67% : 9%) both at 32-36 weeks. Time intervals from the detection of AEDV to delivery of live neonates varied from the day to 15 days. In conclusion, AEDV in the umbilical artery might be of clinical value in routine surveillance of pregnancies complicated by severe pre-eclampsia and eclampsia, and predict hypoxic fetal condition which needs operative interventions before or during labor and mechanical ventilation after birth.

OBJECTIVE: It has been thought that estrogen has neuroleptic like effect in women schizophrenic patients. This study aimed to investigate neuroleptic side-effects severity in women with schizohrenia and to investigate their putative association with variations in sex steroids over menstrual cycle. Based on the estrogen theory, The author hypothesized that parkinsonian side-effects would be exacerbated when estrogen levels were high. METHOD: 26 schizophrenic women were assessed using the ESRS(Extrapyramidal Symptom Rating Scale) and estrogen analysis. Tests were conducted twice, in the mid luteal and mid follicular phase. RESULT: It was hypothesized that high level of estrogen would lead to an exacerbation of parkisonian side-effects but the results indicated that parkinsonian side effects decreased overall when estrogen levels were high. This effects were more marked for the group taking typical neuroleptics than those taking atypical neuroleptics. CONCLUSION: The results of this study suggest that estrogen and progesteron may reduce the severity of neuroleptic indeced extrapyramidal side effects over menstrual cycle in women with schizophrenia. It was concluded that estrogen has different effects on dopamine dynamics in the mesolimbic and mesostriatal pathways according to estrogen, progesteron, catecol estrogen, prolactine.

Human colon epithelial cells secrete an array of proinflammatory cytokines that includes IL-8, MCP-1, GM-CSF, TNF alpha and IL-6. This response may serve to attract neutrophils and macrophags to the site of infection. In addition to IL-8 and MCP-1, the chemokine family contains other members, which, alone or in combination, can recruit and/or activate inflammatory and lymphoid cells. In this study, we asked whether colon epithelial cells express a broader array of chemokines than previously described. The colon epithelial cell line, Caco-2, was stimulated for 3h with IL-1 alpha, or was infected with Salmonella dublin. RNA was extracted and chemokine mRNA levels were determined by quantitative reverse transcription-PCR using internal RNA standards. Ex pression of GRO alpha, GRO beta, GRO gamma and IP-10 increased by bacterial infection or IL-l alpha stimulation. These data strongly support the notion that epithelal cells are an important and integral component of the host's natural immune system.

Segmental non-familial colonic polyposis was first reported by Chiang et al. in 1992. It is characterized by segmental distributlion of colonic polyposis usually confined to the descending colon, absence of family history of polyposis, large bowel malignancy, inflammatory bowel disease, or other pre-malignant colonic conditions. We experienced a nineteen-year-old male, who suffered from 2 years watery diarrhea about five to ten times a day, intermittent hematochezia, and weight loss of 12 kg in a year. He had no family history of colonic polyps, colon cancer, or inflammatory bowel disease. Colon study showed variable sized multiple colonic polyps on the rectum and sigmoid colon. Colonoscopy showed that 0.5 to 1.5 cm sized multiple polyps were scattered from the 6cm site to the 30cm site above the anal verge and the intervening mucosa between polyps was edematous. Colonoscopic biopsy revealed hyperplastic, adenomatous, and mixed hyperplastic and adenomatous polyps, After partial colectomy, we discovered 169 polyps from the resected specimen. After operation, diarrhea and abdominal pain had disappeared. We experienced a case of segmental non-familial polyposis and report it with review of the literatures related to it.

9.Composite Follicular Variant of Papillary Carcinoma and Mucoepidermoid Carcinoma of Thyroid Gland: A Case Report.
Journal of Korean Medical Science 2010;25(11):1683-1687
A 50-yr-old male presented a thyroid mass with dysphasia and hoarseness. He underwent total thyroidectomy and neck node dissection. Pathologically, the tumor had two distinct tumor components with intermingled areas: follicular variant of papillary carcinoma and mucoepidermoid carcinoma. Mucoepidermoid carcinoma composed of columnar cells, mucocytes, and squamoid cells showing solid and cystic lesion. Several small cysts lined by benign ciliated columnar epithelia suggesting that this tumor had originated from solid cell nest were seen around the tumor. By immunohistochemistry, columnar cells and squamoid cells in mucoepidermoid carcinoma were positive for cytokeratin but negative for thyroglobulin, TTF-1 and calcitonin. Positivity of p63 was seen in squamoid cells and basal cells of cysts. Some mucocytes are CEA positive. Tumor cells of papillary carcinoma are positive for TTF-1, thyroglobulin but negative for CEA, calcitonin and p63.

Three cases of hydatidiform mole with a coexisting fetus are described. In two cases, flow cytometric analysis of nuclear DNA content from paraffin-embedded, molar tissues and normal-appearing placental tissues showed diploid pattern. One case had karyotypes of 46, XX both in fetal skin fibroblasts and in molar tissues. Microscopically, the villi showed diffuse hydropic swelling with circumferential trophoblastic proliferations and consistent with the diagnosis of complete mole. Two patient had persistent gestational trophoblastic neoplasia on the follow-up. Therefore, in cases of hydatidiform mole with a coexisting fetus, dizygotic twin pregnancies composed of a normal pregnancy from one ovum and a complete mole pregnancy from the other ovum must be considered and the patients should be followed with serum beta-hCG measurements.
