This study measured the relative displacements of the five-unit fixed partial dentures as cast with the same fixed partial dentures sectioned and assembled by investment-soldering, soldering stand-soldering, and cast-joining techniques. A total of fifteen specimens using a type IV gold alloy wee one-piece cast as control and then sectioned and assembled five test specimens for each method were prepared. A computerized three dimensional coordinate measuring machine and specially designed cylinder for this study were used. Displacement was defined by six displacement variables for the each of cylinders incorporated in each casting: three component displacements ( Lx, Ly, and Lz) and rotational displacements( thetax, thetay, thetaz). The global displacement was computed using the mathematical formula R= Global displacement ={{{{rm SQRT { (x'-x)^2 +(y'-y)^2 + (z'-z)^2} }} }} Under the conditions of this study, the following conclusions were drawn: 1. The investment-soldering group showed the largest mean value of final global displacements, followed by stand-soldering group, cast-joining group and one-piece cast group. However, between the mean values of final global displacement for the cast-joining group and one-piece cast group, there was no significant difference. 2. For investment-soldering and stand-soldering groups, the greater global displacements were recorded in soldering phase than in indexing or investing phase. 3. For one-piece cast group, the displacements occured mostly in the casting phase. And for castjoining group, there was no significant difference in global displacements among the fabrication procedures. 4. Intercentroidal distance decreased in framework-pattering, solder-indexing, solder-standing, and soldering phases, but increased in investment block-investing and casting phases. 5. Specially designed cylinder for touch-trigger type coordinate measuring machine was validated.

PURPOSE: We report clinical charateristics of percutaneous central venous catheteriza- tion(PCVC) that is performed commonly as a vascular access procedure in the neonatal intensive care unit(NICU) including comparision between the success rate and com- plication rate of groups performed by a doctor and by nurses who were accustomed to the IV procedure. METHODS: We evaluated a total of 158 PCVC cases performed in the NICU of Soonchunhyang Chunan hospital over 2 years 5 rnonths from May, 1995 to September, 1997. The 24 cases of PCVC were performed by doctors and 134 cases of this proce- dures were performed by well trained nurses. We have compared success rates, clinical characteristics, insertion sites, indwelling time, causes of removal of the catheters, and associated complication of both doctor performed group (D) and nurse performed group (N) retrospectively. RESULTS: The mean gestational age, birth weight, weight at the time of insertion were significantly lower in the doctor performed group than in the nurse group(P<0.001). There were significant differences in postnatal age and mean duration per catheter in both groups. The overall success rate of insertions was 89.9%(142/158), the success rate of doctor performed group was 54.2%(13/24) and nurse group was 96.3%(129/134) and there was significant difference(P<0.001). In the doctor performed group, 100% were axillary however in the nurse group 43.4% were axillary, 38.8% were antecubital, 9.4% were temporal, and 5.4% were hand. The most common cause of the removal of the catheter was elective in both groups but there was also substantial spontaneous removal by the patients and mechanical complication. Cultures of catheter tips were done after removal in 110 cases, among then were positive in 36 cases(33.6%), the most common causes were Staphylococcus aureus and Candida albicans. CONCLUSION: In this report, the authors emphasize that percutanous central venous catheterization performed by well trained nurses has a higher success rates than the doctor performed group and can be considered safe. We would also like to emphasize that more attention should be paid to the maintanace of PCVC.

The purpose of this study is to evaluate the color differences that can exist between differnet brands of dentin porcelain having identical shade designations. The instrumental colorimetric technique was used to determine these differences. The three brands of dentin porcelain used were Vita VMK-68, Shofu Vintage, and Ceramco II. The three shades selected were the Vita Lumin shades A2, B2, and C2. The color difference values were compared with each other using L*, a*, b*, three variables of the CIELAB color system, and E. The results of this study were as follows: 1. Corresponding shades of different brands of dentin porcelain produced different L*, a*, b* values. 2. The greatest E value in corresponding shade was found to exist between Ceramco II and Shofu Vintage, followed by between Vita VMK-68 and Ceramco II, and then between Vita VMK-68 and Shofu Vintage. 3. The E values in shade C2 were mainly influenced by L* value ; however none of L*, a*, b* values had greater influence on E values than the others in shade A2, B2. 4. Shofu Vintage had the highest b* value, followed by Vita VMK-68, and then Ceramco II.

Thirty patient with essential hypertension were administered Manidipine, a new calcium antagonist, 10~20mg once daily to evaluate the hypotensive efficacy and safety for 8 weeks. And the followings were the result. 1) Patients were consists of 14 male, 16 female, aged 53 in average and classified as mild in 21 and moderate in 9 patients. 2) Optimum intial dose was 10mg and 10 to 20mg were the doses recommended. 3) Blood pressure dropped after 8 weeks 24/13mmHg in average, rewarding 80% effectiveness and normalized in 87%. 4) Most frequent side reaction was facial flushing in 5 patiens followed by palpitation and dizziness, all of which did not disturb the continuation of medication. 5) Most of routine laboratory parameter were normal and unchanged between before and after the trial. 6) Overall rating of usefulness was 77%. In conclusion, Manidipine 10 to 20mg once daily regimen is well tolerated and effective in the treatment of mild to moderate essential hypertension.

This study was undertaken to investigate the morphologic changes following flushing, preservation and reperfusion procedures in a canine lung allotransplantation model. Donor lungs were flushed with modified Euro-Collins (MEC) solution, low potassium dextran glucose (LPDG) solution or University of Wisconsin (UW) solution, then stored at 10oC for 20 hours. Light microscopic and electron microscopic features of the lungs were examined after flushing, preservation and 2 hours after reperfusion. After flushing light microscopy showed focal mild alveolar collapse and interstitial edema. After preservation the lung tissue showed multiple foci of alveolar collapse, consolidation, and alveolar epithelial cell damage. After reperfusion the lung tissue showed diffuse alveolar collapse, consolidation and many destroyed cellular debris in the alveolar lumina. After flushing electron microscopy showed focal alveolar collapse and mild swelling of type I epithelial cells. After preservation both type I epithelial cells and endothelial cells were swollen and destroyed focally. Some type I epithelial cells were detached from the basal lamina. The endothelial cells showed luminal protrusion of tactile-like structure and vacuoles of the cytoplasm. After reperfusion the lung tissue showed fibrin material in the alveoli, prominent type I epithelial cell swelling with fragmented cytoplasmic debris and marked endothelial cell swelling with vacuoles or tactile-like projections. The alveolar macrophages showed active phagocytosis. After preservation scanning electron microscopic examination of the pulmonary arteries showed multiple patchy areas of swelling or conglomerated lesions in the inner surface of the pulmonary arteries. In conclusion, the ultrastructural changes associated with flushing were mild in severity, the donor lungs were injured during the preservation, and further damage occurred during the reperfusion.
