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.

Angiodysplasia of small bowel is uncommon and frequently undiagnosed and presents a taxing surgical problem. It is usually diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that the lesion is impalpable, and invisible to the naked eye, so it usually cannot be identified unless bleeds actively at the time of surgery. Arteriography gives a little information about wax and wane pattern of bleeding in the lesion. Endoscopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few millimeters in diameter. Transillumination of the intestinal wall from inside of the lumen to the outside in a dark room can define the precise vascular anatomy of the wall. The delicate lesion of the angiodysplasia can be identified by this transillumination method. We described a simple intraoperstive endoscopic translllumination technique used successfully to identify an angiodysplasia in the small bovwel prior to the bowel resecion. This report summarized our experience and review of literature.

We report one case of adenoma malignum of the cervix. Adenoma malignum is an extremely well-differentiated form of adenocarcinoma in which the branching glandular pattern strongly simulates that of the normal endocervical glands. This term has been used to describe a very well-differentiated adenocarcinoma characterized histologically by distorted and architecturally irregular endocervical glands which penetrate deeply into the wall of the cervix, but with minimal and focal evidence of glandular cell stratification, anaplasia, or mitotic activity. Despite this innocuous histologic appearance, these tumors have classically been thought to be clinically highly malignant, with an almost invariably rapid lethal outcome. The diagnosis of minimal deviation adenocarcinoma (adenoma malignum) of the endocervix may be difficult. The diagnosis was adenocarcinoma on the Pap Smear treatment has been hysterectomy.

PURPOSE: Measles infection in children has been known to have many complications including hepatitis. But there has been no appropriate study about measles hepatitis in children. So we studied to facilitate the understanding of measles hepatitis in children by analyzing their clinical features and laboratory findings. METHODS: We investigated 164 patients who were admitted to the Department of Pediatrics, Seoul Red Cross Hospital due to measles from January 1985 to December 1994. We excluded other factors such as hepatitis A, B, C virus, Epstein-Barr virus and cytomegalovirus which could also result in hepatitis. According to the presence and the absence of coexistent complications 22 measles hepatitis patients were divided into two groups in which clinical characteristics and laboratory findings were analyzed as well. RESULTS: 1)Of total 164 patients there were 26 patients(15.9%) with measles hepatitis. 2)The ratio of male to female was 1.8:1. The range of age distribution was 6 months to thirteen years, and patients from 6 months to 3 years of age occupied 50% of the total patients. 3)The mean values of serum AST and ALT levels were 151+/-17.6 IU/L and 185+/-36.6 IU/L, espectively. And they were detected at 4.4+/-2.4 days after the first symptoms of measles were developed. 4)Major clinical characteristics were diarrhea in 22.7%, vomiting in 13.6%, hepatomegaly in 9.1%, and splenomegaly in 4.5%. Jaundice was not detected. 5)There was no difference between two groups in terms of serum albumin, globulin, bilirubin, AST and ALT(p>0.05). 6)Elevated serum AST and ALT levels returned to normal values within 2 weeks in 87.5%. CONCLUSIONS: Measles hepatitis develops with favorable outcome. Liver function test may well be done in cases of measles infection because hepatic dysfunction does not uncommonly occur in measles infection. Further study for the difference of the incidence of measles hepatitis according to the measles epidemics should be performed.

MRI findings of extramedullary hematopoiesis of the spleen have not been described in the literature. Wereport the MRI features of this condition, as seen in two patients and confirmed by fine needle biopsy. Threesmall masses(< or =3cm) were isointense on T1WI, hyperintense on T2WI, and enhanced after the injection of gadolinium.Two 6cm-sized masses were hypointense on both T1WI and T2WI, and showed no contrast enhancement.

Renal osteodystrophy is well recognized complication of end stage renal disease(ESRD) and is associated with a marked morbidity. To evaluate bone loss in renal osteodystrophy, we measured bone mineral density(BMD) in distal radius by quantitative computed tomography in 43 ESRD patients on starting hemodialysis(HD) and in 84 healthy controls matched for age and sex. We also measured intact parathyroid hormone(iPTH), serum total alkaline phosphatase(T-ALP), osteocalcin(OC) and urine deoxypyridinoline(U-DPD) as bone turn-over markers. 1) The mean age of ESRD patients and control groups were 49.8 and 49.7 years. M:F ratio were 1:1.1 and 1:1.3 on each groups. There was no significant differences on each groups. 2) Serum T-ALP and OC were 263.9+/-264.5U/L, 43.5+/-27.6ng/mL in ESRD patients and 167.4+/-46.6U/ L, 8.8+/-3.9ng/mL in control groups. These were significantly higher in ESRD patients(P<0.001, P< 0.001), while U-DPD were not significant difference on each groups(5.3+/-4.1 vs 5.4+/-1.9nM/mM. Cr.). 3) Serum iPTH and aluminum were 296.8+/-263.4pg/mL, 10.1+/-11.6ng/mL in ESRD patients. 4) Total density, trabecular density and cortical density were 340.4+/-83.6, 172.9+/-48.4, 477.2+/-123.5mg/ cm3 in ESRD patients and 393.2+/-49.1, 210.6+/-32.9, 541.3+/-76.2mg/cm3 in control groups. BMD was statistically significantly reduced in ESRD patients (P<0.001, P<0.001, P<0.001, respectively). Z score of total density and trabecular density were -0.62+/-1.12, -0.91+/-0.95 in ESRD patients and 0.19+/-0.68, 0.06+/-0.59 in control groups. It was significantly reduced in ESRD patients(P<0.001, P<0.001, P<0.001, respectively). 5) In ESRD patients, serum T-ALP, iPTH, OC, U-DPD were not correlated with BMD and Z score. But in control groups, serum OC was correlated inversly with BMD, and U-DPD was only correlated inversely with trabecular density. 6) In ESRD patients(n=22) who were having iPTH above 300pg/mL, serum OC and U-DPD were significantly higher than in ESRD patients(n=21) who were having iPTH below 300pg/mL(52.6+/-28.8ng/ mL, 6.8+/-5.1nM/mM.Cr. vs. 33.9+/-23.3ng/mL, 3.7+/-1.9 nM/mM.Cr. P<0.05, P<0.05 repectively). But serum aluminum, and T-ALP were not significant difference on each groups. BMD and Z score were also not difference on each groups. 7) In ESRD patients who were having iPTH above 300pg/mL, iPTH and serum OC were inversely correlated with BMD but U-DPD were only inversely correlated with trabecular density. In ESRD patients who were having iPTH below 300pg/mL, bone turn-over markers were not correlated with BMD. In ESRD patients on starting HD, BMD were significantly reduced, but serum T-ALP, OC, iPTH and U-DPD were not correlated with BMD. In ESRD patients who were having iPTH above 300 pg/mL, BMD were significantly inversely correlated with serum OC, iPTH.

For the purpose of preparing the fundamental data on air pollution in underground shopping center and also contributing to the health improvement of resident, the authors measured the level of SO2, NO2, TSP, CO, CO2 and also some related factors as air temperature, air movement, relative humidity and mean radiation temperature at inside and outside of underground shopping center in Pusan from January to February and from July to August 1994. The results were as follows: 1. The mean concentration of CO within the underground shopping center was 3.1+/-1.3ppm in winter and 2.1+/-0.9 ppm in summer. There was a negative correlation (p<0.01) between inner CO concentration and temperature in summer and no correlation between inner CO concentration and outer CO concentration in underground shopping center 2. The mean concentration of C02 within the underground shopping center was 876+/-353 ppm in winter and 757+/-125 ppm in summer. There was a negative correlation (P<0.01) between inner CO2 concentration and air movement in summer and positive correlation (p<0.05) between inner CO2 oncentration and outer CO2 concentration in underground shopping center. 3. The mean concentration SO2 within a underground shopping center was 0.036+/-0.019ppm in winter and 0.040+/-0.013ppm in summer. There was a positive correlation(p<0.01) between inner SO2 concentration and positive correlation between inner SO2 concentration and outer SO2 concentration in summer and winter in Underground shopping center. 4. The mean concentration of NO2 within a underground shopping center was 0.052+/-0.038ppm in winter and 0.042+/-0.016ppm in summer. There was a no correlation between inner NO2 concentration and thermal factors in summer and winter and low correlation between inner NO2 concentration in underground shopping center. 5. The mean concentration of TSP within a underground shopping center was 430+/-214 microgram/m3 in winter, 366+/-73 microgram/m3 in summer, and very in excess of the atmospheric environmental quality standards of Korea(150 microgram/m3). There was low correlation between inner TSP concentration and temperature in summer and high correlation between inner TSP concentration and outer TSP concentration in underground shopping center.
