In modem medical industries as in others, it has been emphasized by many experts such as Dr. Mayer and Dr. Donabedean that there should be quality assurance activities applying statistical knowledges in the processes of medical management and medical staff themselves for the better medical care and customer satisfaction. Three of our quality assurance programs for the purpose of shortening the treatment time In the department of emergency medicine in Keimyung University, Dong-San Medical Center had been carried out during the period of June 94 through December 95. Our methodology was mainly the process emphasized ; finding the causes of delaying factors in various processes related to the works of nurses, doctors, laboratory services, radiology services etc. in the emergency room, holding various meetings among the related groups with genuine discussions, notifying the new results in each step, encouraging the positive ones and also applying the new leadership technics. During the period of June 94 through December 95(for 1.5 years), the average E.R. patient treatment time from registrations to dispositions had been reduced by about 2 hours (from 5 hours 3 minutes to 2 hours 5 minutes) and its variations among the different specialities had been narrowed down to significant degree (p<0.05) revealing the preprogram base line standard deviation of 2.43 to 1.28 in post program through continuous quality assurance programs. It was also noted that the successful results of Q/A program have been closely related to the fact that the process should be designed and redesigned repeatly as needed and that all the participants related were actively involved in the planning and redesigning processes.

7 cases of acute gastric Anisakiasis have been reviewed at the Department of Internal Medicine, Yeungnam University Hospital from March, 1983 to December 1986. 1. Of 7 cases, the ratio of male and female was 3:4 and the age 30s occupied most (5 cases) the 50s' followed (2 cases). 2. Chief complains were in order of epigastric pain (6 cases), vomiting (3 cases), Nause (2 cases), Ulticaria (1 case) & epigastric fulling sensation (1 case). 3. In all 7 cases, the causative fish in astroconcer myriaster. 4. The onset of symptoms was observed within 5 to 7 hours after eating the causative raw fish. 5. Gastrofiberscopic exam was undergo within 48 hours since onset of symptoms. 6. The gastrofiberscopic findings were gastric mucosal edema and redness in all 7 cases. One case also had mucosal erosion. The involved sites of the stomach were in frequency of order, the body (5 cases), the antrum (2 cases). 7. The symptoms of the patients relieved spontaneously without medical treatment after the extraction of the larva with biopsy forcep during gastrofiberscopy. 8. In Korea, many people take raw fish and there may be many patients of Anisakiasis so if much concern and careful observation are paid to whom with severe cramping epigastric pain after taking of raw marine fish in about 10 hours, we could find out and confirm more patients suffering from Anisakiasis by immediate endoscopic gastrofiberscopy.

Acquired tufted angioma is a benign, slowly progressive angioma with a typical histological pattern that was first described by Wilson-Jones in 1976. We report a case of acquired tufted angioma in a 19 year old female who had erythematous papules and plaques on the right thigh. Histopathological findings showed multiple capillary lobules in a cannonball arrangement scattered throughout dermis, which was diagnostic of acquired tufted angioma.

Objectives: We sought to identify a clinically useful method of analyzing orbital dystopia to aid in diagnosis and treatment planning and to quantify vertical discrepancies in eye level and variations in canthal tilt in Koreans. Patients and Methods: In 76 Korean patients with a mean age of 23.12 years, mean differences in the level of the pupils, lateral canthi, medial canthi, and canthal tilt were measured. The difference in pupil level was calculated from the perpendicular lines drawn from the midpupil area of each eye to the midline of the face to determine the amount of skeletal discrepancy of the eye. Soft tissue discrepancies were determined according to the vertical difference between the lines drawn from the lateral or medial canthus of each eye perpendicular to the midline of the face. The canthal tilt was determined from the inclination of a line connecting the lateral and medial canthi, then classified as class I, II, or III. Results: Mean differences in pupil level, medial canthi, and lateral canthi were 1.57±1.10 mm, 1.14±1.07 mm, and 2.03±1.64 mm, respectively. The mean degree of canthal tilt were 8.45°±3.53° for the right side and 8.42°±3.81° for the left side. No study participants presented with class III canthal tilt. The mean canthal tilt values for those with class I tilt were 3.21°±1.68° for the right side and 3.18°±1.63° for the left side, while, for those who had class II tilt, the values were 9.60°±3.66° for the right side and 9.54°±2.99° for the left side. Conclusion The presented diagnostic method of orbital dystopia can be used to effectively establish a treatment plan that takes into consideration the patient’s skeletal and soft-tissue discrepancies.

OBJECTIVE: This study was to compare the characteristics between parthenogenetic mES (P-mES) cells and in vitro fertilization mES cells. MATERIAL AND METHODS: Mouse oocytes were recovered from superovulated 4 wks hybrid F1 (C57BL/6xCBA/N) female mice. For parthenogenetic activation, oocytes were treated with 7% ethanol for 5 min and 5microgram/ml cytochalasin-B for 4 h. For IVF, oocytes were inseminated with epididymal perm of hybrid F1 male mice(1x106/ml). IVF and parthenogenetic embryos were cultured in M16 medium for 4 days. Cell number count of blastocysts in those two groups was taken by differential labelling using propidium iodide (red) and bisbenzimide (blue). To establish ES cells, blastocysts in IVF and parthenogenetic groups were treated by immunosurgery and recovered inner cell mass (ICM) cells were cultured in LIF added ES culture medium. To identity ES cells, the surface markers alkaline phosphatase, SSEA-1, 3, 4 and Oct4 staining were examined in replated ICM colonies. Chromosome numbers in P-mES and mES were checked. Also, in vitro differentiation potential of P-mES and mES was examined. RESULTS: Although the cleavage rate (> or =2-cell) was not different between IVF (76.3%) and parthenogenetic group (67.0%), in vitro development rate was significantly low in parthenogenetic group (24.0%) than IVF group (68.4%) (p<0.05). Cell number count of ICM and total cell in parthenogenetic blastocysts (9.6+/-3.1, 35.1+/-5.2) were significantly lower than those of IVF blastocysts (19.5+/-4.7, 63.2+/-13.0) (p<0.05). Through the serial treatment procedure such as immunosurgery, plating of ICM and colony formation, two ICM colonies in IVF group (mES, 10.0%) and three ICM colonies (P-mES, 42.9%) in parthenogenetic group were able to culture for extended duration (25 and 20 passages, respectively). Using surface markers, alkaline phosphatase, SSEA-1 and Oct4 in P-mES and mES colony were positively stained. The number of chromosome was normal in ES colony from two groups. Also, in vitro neural and cardiac differentiation derived from mES or P-mES cells was confirmed. CONCLUSION: This study suggested that P-mES cells can be successfully established and that those cell lines have similar characteristics to mES cells.

OBJECTIVE: This study was to investigate the generation of the functional neuron derived from human embryonic stem(hES,MB03) cells on in vitro neural cell differentiation system. METHODS: For neural progenitor cell formation derived from hES cells, we produced embryoid bodies (EB: for 5 days, without mitogen) from hES cells and then neurospheres (for 7~10 days, 20 ng/ml of bFGF added N2 medium) from EB. And then finally for the differentiation into mature neuron, neural progenitor cells were cultured in i) N2 medium only (without bFGF),ii) N2 supplemented with 20 ng/ml platelet derived growth factor-bb (PDGF-bb) or iii) N2 supplemented with 5 ng/ml brain derived neurotrophic factor (BDNF) for 2 weeks. Identification of neural cell differentiation was carried out by immunocytochemistry using betaIII-tubulin (1:100) and GFAP (1:500). Also, generation of functional neuron was identified using anti-glutamate (Sigma, 1:1000), anti-GABA (Sigma, 1:1000), anti-serotonin (Sigma, 1:1000) and anti-tyrosine hydroxylase (Sigma, 1:1000). RESULTS: In vitro neural cell differentiation, neurotrophic factors (PDGF and BDNF) treated cell groups were high expressed MAP-2 and GFAP than non-treated cell group. The highest expression pattern of MAP-2 and betaIII-tubulin was indicated in BDNF treated group. Also, in the presence of PDGF-bb or BDNF, mostof the neural cells derived from hES cells were differentiated into gultamate and GABA neuron in vitro. Furthermore, we confirmed that there were a few serotonin and tyrosine hydroxylase positive neuron in the same culture environment. CONCLUSION: This results suggested that the generation of functional neuron derived from hES cells was increased by addition of neurotrophic factors such as PDGF-bb or BDNF in b-FGF induced neural cell differentiation system and especially gultamate and GABA neurons were mainly produced in the system.
