The purpose of this study was to evaluate and compare the fit of denture bases processed by injection pressing technic using laser scanner of reverse engineering technic. The auther duplicated 20 maxillary edentulous models and 20 mandibular edentulous models, which were scanned on HYSCAN 45C 3D SCANNER(Hymarc Co., Canada). The scanned data was stored in the personal computer using SURFACER (Imageware Co., U.S.A.) software program. After 40 dentures were cured by PERform Inkovac system. SR-Ivocap system, Palajet system, and Sulfon system, they were stored in water at room temperature for 24 hours. The dentures were scanned on HYSCAN 45C 3D SCANNER(Hymarc Co. Canada). The scanned data were stored in the personal computer using SURFACER (Imageware Co., U.S.A) software program. By overlapping two images using the same program, the fit between two surfaces was scaled by positive and negative errors. The obtained results were as follows : 1. In the upper denture, most of the positive errors occurred on the lingual side of anterior alveolar ridge and the negative errors were on the flange of denture bases. 2. In the lower denture, most of the positive errors occurred on the inner side of lingual flange and the negative errors were on the border of anterior labial flange areas. 3. There were no statistical differences among the positive errors of the four types of inject-ion denture curing methods and also no statistical differences between negative errors except only in negative maximum errors. 4. In PRERform system and SR-Ivocap system, they have the tendency of inaccurate fit lower denture bases comparing to that of upper denture bases. 5. The negative error scales were greater than the positive error scales in all types of inject-ion denture curing methods.

Objective The paper analyzes the operating patterns of the outpatient process and identifies the links needing reengineering so as to provide scientific basis for the optimal allocation of outpatient resources and process reengineering and prove the rationality and feasibility of using the queuing theory. Methods Using the methods of the queuing theory, the service time and the patients' arrival time at such service links as registration, billing and accounting, internal medicine, and gynecology in the outpatient department of a certain hospital were measured and the operational indexes at various links such as service intensity, average queuing length, average queuing time, average stay, probability of the service desks being idle, and the probability of the patients having to wait were calculated so as to estimate the rational number of service desks and the optimal value of the sum of the cost of waiting and the cost of service. Results Registration, billing and accounting , service intensity in internal medicine, personnel allocation, and queuing time were basically rational in the outpatient department of the hospital surveyed. One more physician should be added to the gynecology department so as to improve efficiency and reduce patients' waiting time and queuing length. There was currently a shortage of medical staff in the hospital. The cost of hospital input was moderate while the cost of waiting was on the high side. Conclusion It is rational and feasible to evaluate the efficiency of the outpatient process with the methods of the queuing theory. The method deserves to be spread.

Objective:To identify the function of extracellular soluble vimentin that promotes proliferation, activation and chemotaxis of inflammatory cells. Methods: The proliferation of rat splenocytes stimulated with vimentin was evaluated in vitro. The lymphocyte counts and vimentin-antibody levels of peripheral blood in mice immunized with vimentin were detected in vivo. Peritoneal macrophages were collected and cultured with different concentrations of vimentin to detect the effect on phagocytosing chicken red blood cells. The chemotaxis of NIH3T3 fibroblast towards vimentin was observed in transwell chamber. Results:In vitro vimentin dose dependently promoted the proliferation of splenocytes. The proliferation indexes of primed and naive splenocytes cultured with 16μg/ml vimentin were reached up to ( 196. 0 ± 9. 7 )% and ( 208. 9 ± 4. 6 )% respectively without significant difference. In vivo vimentin significantly enhanced the lymphocytes number(109 L-1)of peripheral blood(5. 74±0. 51 vs. 1. 69±0. 13)and the levels of vimentin specific antibody( OD value 2. 31 ± 0. 06 vs. 0. 19 ± 0. 08 ) that shown no significant difference from immunization with vimentin plus CFA. In vitro vimentin dose dependently stimulated phagocytic ability of macrophages and performed the chemotactic effects on NIH3T3 fibroblasts. Conclusion:Extracellular soluble vimentin promotes the proliferation,activation and chemotaxis of concerned inflammatory cells and possesses the functions as an alarmin.

PURPOSE: To investigate the effect of triamcinolone acetonide (TA) on the survival, nitric oxide (NO) production, and migration of cultured human trabecular meshwork (TM) cells. METHODS: After exposure to TA, indomethacin, and dexamethasone for 2 days, the survival and nitrite production of the primarily cultured human TM cells were assessed with MTT and Griess assays respectively. The effect of co-exposure to the NO donor, sodium nitroprusside, was also assessed. A migration assay was done to evaluate the effect of TA on the activity of TM cells. RESULTS: Cellular survival increased after exposure to TA at low concentration but decreased at high concentration. TA decreased the production of NO significantly (p<0.05). Exposure to indomethacin and dexamethasone revealed similar results. TA reversibly inhibited the migration of TM cells. CONCLUSIONS: TA decreases the production of NO and inhibits the migration of TM cells. TA at high concentration decreases cellular survival accompanied with decreased NO production. These effects of TA on TM cells may result in the elevation of intraocular pressure.

The authors retrospectively evaluated 75 diabetic patients (92 eyes) who underwent cataract surgery between January 1995 and December 1997. The minimum follow up period was one year. We analysed retrospectively the final visual cuity, the incidence and risk factors of progression of diabetic retinopathy after cataract surgery. The improvement of visual acuity more than 2 lines was achieved in 81 eyes (88.0%). Seventy two eyes (78.3%) achieved the final visual acuity of more than 0.5. In moderate or severe nonproli- ferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy(PDR)groups, visual acuity improvement was less than in no or mild NPDR group (p=0.001). Progression of retinopathy occurred in 21 out of 82 eyes (25.6%)one year following surgery and was associated with presence of diabetic nephropathy (p=0.018). The rates of retinopathy progression were higher in patients with longer duration of diabetes or insulin treatment than shorter duration of diabetes, or dietary or oral hypoglycemic treatment, but differences did not reach a significant level.

Double elevator paralysis is a syndrome in which the superior rectus and the inferior oblique muscle of the same eye are paralyzed. The authors have experienced a case of double elevator paralysis with 35 prism diopters hypotropia and 20 prism diopters exotropia on the right eye. The patient was 19 years old female who visited our hospital because of poor cosmetic appearance. Knapp procedure was performed primarily to correct hypotropia, but 20 prism diopters hypotropia remained. 5 months later, a second operation was performed consisted of 7.5 mm recession of the left lateral rectus and 5mm recession of the right inferior rectus in order to correct the exotropia and residual hypotropia. After the second operation, ocular position in primary position was nearly orthophoric and upward movement of the right eye was considerably improved.

Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.
