Objective: The purpose of this study is finding tendencies admission patients to orient medical hospital due to Traffic Accident. Method: We studied 34 cases who were admitted in Dong-eui University Oriental Hospital from 1st, December, 2003 to the 30st, May, 2005. And we came to some conclusion about clinical tendencies as follows. Results and Conclusions: 1. Women had occupied more than men, And 10 persons in 30th were the most distribution of age. 2. Most patients used western medical hospital as primary hospital and after several days they started to search for orient medical treatments. 3. In the diagnosis through radiological test, cervical spine sprain was most(19 cases, 55.6%). The others were lumbar spine sprain(14 cases, 41.2%), fracture of other bone{4 cases, 11.8%), fracture of spine(3 cases, 8.8%), Intercranial hemorrhage(3 cases, 8.8%). 4. In chief complaint, low back pain was most(19 cases, 55.9%), The others were neck stiffness(17 cases, 50.0%), headache(13 cases, 38.2%), lower limb pain(9 cases, 26.5%). 5. Simple Disease had higher than complex disese at effective rate. 6. Both $43{\sim}60$ days admission and $15{\sim}21$ days admission were the best effective. $8{\sim}14$ days admission was next effective. 7. Early visit made more effective.

The purpose of this study was to analyze the status of school foodservice facilities, utilities and equipment & sanitary education in provinces, This study was carried out from September 2008 until December 2008 and is targeted towards schools' dietitians that work at schools with school foodservice. 1,623 schools participated in this research and Kangwondo, Choongchungdo including the metropolitan area with frequent occurrence of food bone disease were the targets of this research. The regional distribution of this research is as follows; 377 schools in Seoul, 648 schools in Gyeonggido, 160 schools in Kangwondo, 438 schools in Choongchungdo equaling 1,623 schools in total. And out of the total 1,623 schools, 815 (50.2%) were elementary schools and 808 (48.8%) were middle and high schools (p < 0.001). Most of the elementary schools, excluding 4 schools, were self-operated. In the case with middle and high schools, 81.5% (513 schools) were self-operated and 18.4% (295 schools) were contracted. When dealing with the sanitation management of school foodservice in Kangwondo and Seoul, elementary schools were less equipped with equipment and facilities than middle and high schools which proved that they were in need of improvements (p < 0.01). Schools with self-operated foodservice, in particular, were in need of preparation zone improvements. 52.3%~88.0% of stainless equipment such as utensils, spoons/chopsticks, subsidiary food tray, and food trays were sterilized by dryers. Work tables, vegetable slicers, and mincers were chemically sterilized and plastic materials were sterilized by ultraviolet rays. Data from newspapers, Internet and TV are collected beforehand and then an annual hygiene educations plan for employees are put together. Hygiene education for employees are carried out monthly through oral method.

Recurrent macrophage activation syndrome (MAS) is very rare. We present the case of an adolescent boy with human leukocyte antigen (HLA) B27-positive ankylosing spondylitis (AS), who experienced episodes of recurrent MAS since he was a toddler. A 16-year-old boy was admitted because of remittent fever with pancytopenia and splenomegaly after surgical intervention for an intractable perianal abscess. He had been diagnosed with hemophagocytic lymphohistiocytosis (HLH) 4 different times, which was well controlled with intravenous immunoglobulin and steroids since the age of 3. We were unable to identify the cause for the HLH. He remained symptom-free until the development of back pain and right ankle joint pain with swelling at 15 years of age. He was diagnosed with HLA B27-positive AS with bilateral active sacroiliitis. He showed symptom aggravation despite taking naproxen and methotrexate, and the symptoms improved with etanercept. On admission, his laboratory data showed leukopenia with high ferritin and triglyceride levels. Bone marrow biopsy examination showed histiocytic hyperplasia with hemophagocytosis. There was no evidence of infection. He received naproxen alone, and his symptoms and laboratory data improved without any other immunomodulatory medications. Genetic study revealed no primary HLH or inflammasome abnormalities. In this case, underlying autoimmune disease should have been considered as the cause of recurrent MAS in the young patient once primary HLH was excluded.

Between 1975 and 1992, forty five patients with trachea stenosis received tracheoplasty for relief of obstruction. The causes of airway problem are brain contusion[19 cases, 40%], cerebrovascular disease[3 cases, 7%], drug intoxication[8 cases, 18%], psychotic problem[2 cases, 4%], trachea tumor[3 cases, 7%], adult respiratory distress syndrome[9 cases, 20%] and direct trauma[1 case, 2%]. Direct causes of trachea stenosis were complications of tracheostomy[36 cases, 80%], complications of nasotracheal intubation[5 cases, 11%], tumor[3 cases, 6%] and trauma[1 case, 2%]. Thirty one patients underwent the sleeve resection and end-to-end anastomosis. Five patients performed a wedge resection and end-to-end anastomosis. Forteen patients received the Montgomery T-tube for relief of airway obstruction. Four patients have done simple excision of granulation tissue. Two, subglottic stenosis patients were received Rethi procedure[anterior division of cricoid cartilage, wedge partial resection of lower thyroid cartilage and Montgomery T-tube molding] and the other subglottic stenosis patient underwent permanent trachea fenestration. Including cervical flexion in all patients postoperatively, additional surgical techniques for obtain tension-free anastomosis were hyoid bone release technique in two cases, and hilar mobilization, division of inferior pulmonary ligament and mobilization of pulmonary vessel at the pericardium were performed in one case. Cervical approach was used in 39 cases, cervicomediastinal in 12 cases and transthoracic in one case. Complications of tracheoplasty were formation of granulation tissue at the anastomosis site[3 cases], restenosis[9 cases], trachea-innominate artery fistula[2 cases], wound infection[2 cases], separation of anastomosis[2 cases], air leakage[3 cases], injury to a recurrent laryngeal nerve[temporary 8 cases, permanent 2 cases] and hypoxemia[1 case]. Surgical mortality for resection with primary reconstruction was 6.7%, with one death due to postoperative respiratory failure and two deaths due to tracheo-innominate artery fistula.

Periodontal therapy has dealt primarily with attempts at arresting progression of disease, however, more recent techniques have focused on regenerating the periodontal ligament having the capacity to regenerate the periodontium. The effect of chitosan(poly-N-acetyl glucosaminoglycan), a carbohydrate biopolymer extracted from chitin, on periodontal ligament regeneration is of particular interest. The purpose of this study was to evaluate the effect of chitosan on the human periodontal ligament fibroblasts(hPDLFs) in vitro, with special focus on their proliferative properties by M'IT assay, the synthesis of type I collagen by reverse transcription-polymerase chain reaction(RT-PCR) and the activity of alkaline phosphatase(ALP). Fibroblast populations were obtained from individuals with a healthy periodontium and cultured with ${\alpha}MEM$ as the control group. The experimental groups were cultured with chitosan in concentration of 0.01,0.1, 1,2mg/ml. The results are as follows; 1. Chitosan-induced proliferative responses of hPDLFs reached a plateau at the concentration of O.lmg/ml(p<0.05). 2. When hPDLFs were stimulated with 0.lmg/ml chitosan, mRNA expression of type I collagen was up-regulated. 3. When hPDLFs were stimulated with 0.lmg/ml chitosan, ALP activity was significantly up-regulated(p<0.05). In summary, chitosan(0.lmg/ml) enhanced the type I collagen synthesis in the early stage, and afterwards, facilitated differentiation into osteogenic cells. The results of this in vitro experiment suggest that chitosan potentiates the differentiation of osteoprogenitor cells and may facilitate the formation of bone.

Aplastic anemia is a disease characterized by general lack of bone marrow activity; It may affect not only the red blood cells but also the white blood cells and platelets, resulting in pancytopenia. Spontaneous gingival hemorrhage is present in some cases and it is related to the blood platelet deficiency. This case report presents the periodontal treatment of a patient with aplastic anemia. A 43-year-old female was referred for continuous gingival bleeding after periodontal treatment. Periodontal findings revealed generalized gingival imflammation, oozing of blood from gingival crevice, and it was diagnosed as adult periodontitis. Root planing and extraction of the upper left third molar with poor prognosis were put into operation after elevation of the platelet count with platelet transfusion. The extraction socket was sutured with 3-0 silk. Bleeding continued even after digital compression at the upper right second premolar, second molar, and left canine areas, which presented severe inflammation. Although platelets were transfused repeatedly, platelet count did not stay elevated since survival rate of the transfused platelets were low due to alloimmunization. Thrombin gauze packing was not effective. Bleeding ceased 3 days after treatment with transfusion of donor platelets. 20 days after the treatment, the gingiva was generally healthy except upper right second premolar and lateral incisor areas. The result of periodontal treatment was good, but bleeding control after treatment was troublesome. In the periodontal treatment of patient with aplastic anemia, elevation of the platelet count with platelet transfusion seems to be the best method for hemorrhage control.

Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder involving eyes, kidney and nervous system, and occurs predominantly in mostly males. The patients with Lowe syndrome are characterized with prominent forehead, thin and sparse hair, protruding ears, congenital cataracts, glaucoma, mental retardation, stunted growth, hypotonia, decrease in muscle mass and tendon reflexes, renal tubular dysfunction, and metabolic bone disease. A 6-year-old boy with Lowe syndrome was admitted to our clinic, with multiple caries and a chief complaint of intermittent pain on the left mandibular molar area. Because of difficulty in management of behavior and his medical problem, general anesthesia was performed for dental care. No specific complication was noticed during dental treatment procedure under general anesthesia and also during periodic recall-checks. General anesthesia itself, however, could be a potentially life-threatening procedure due to patient's biomedical problems. When a dental procedure under general anesthesia is to be required in patient with Lowe syndrome, it may be advisable being teamed with physicians, and general anesthesia duration should be as short as possible.

Werner's syndrome is a rare autosomal recessive disorder manifesting as premature aging. It is also known to be characterized by a high frequency of malignant tumors, especially sarcomas. However, Werner's syndrome may be not only a premature aging disease but also a cancer syndrome, because the malignant tumors in these patients are different from those of normal population with respect to involved site, histological type, and age of onset. Recent studies found Werner's syndrome was caused by a mutation of Werner helicase suggesting that WRN helicase may participate in metabolism and repair of DNA. And a dysfunction of WRN helicase may induce the genomic instability causing somatic mutations. Further studies of Werner's syndrome associated with sarcoma might give much informations about the normal aging process and the pathogenesis of sarcomas.

The aim of this study was to establish an experiment animal model for easy diagnosis and monitoring effect of treatment of cholelithiasis by cholesterol and mixed gall stone. In 12 adult beagle dogs, five dogs there were in the control group and seven dogs in the experiment group with ligated cystic duct. General clinical signs were recorded, CBC and blood chemistry were examined. Control group and experiment group were evaluated every 2 weeks for a period of 20 weeks. The results were (1) Total blirubin, cholesterol, alanine aminotransferase (ALT), aspartate aminotransferase (AST) activity were significantly higher in the experiment group with ligated cystic duct than control group during 2-8 weeks. (2) Total alkaline phosphatase (TALP) activity was significantly higher when compare with control group during 2-8 weeks. Bone alkaline phosphatase(BALP) activity was increased slightly between 2 and 8 weeks but was decreased between 10 and 20 weeks. (3) Blood urea nitrogen (BUN) was decreased between 2 and 8 weeks. After 10 weeks, this was in normal range. (4) On complate blood count (CBC), $Ca^{2+}$ and P were not changed until 20 weeks. (5) On clinical signs in experimental group, they observed a depression, yellow color of mucus membrane and conjunctiva, xanthinuria and xanthochromic. The present study showed that the experimental animal model with ligated cystic duct was a useful model to study biliary tract disease.
