It is the purpose of this article to determine various normal anatomic measurements of temporomandibular joint and normal range of condylar movement using relatively simple X-ray equipment and radiographic technique in consideration of popular clinical application. Author's cases condisted of 100 clinically normal adult males and temporomandibular joint radiographs of 3 serial position so condylar head were taken by transcranial obliquelateral pojection in each case. The serial positions are centric occlusion, 1 inch opening and maximal opening position. The results were as follows; 1. In cetric occlusion, the length between the condylar head and glenoidfossa was 2.23±0.58mm in anterior part, 3.55±0.80mm in upper part and 2.76±0.72mm in posterior part. 2. Incentric occlusion, the angle (alpha) between the horizontal standard line(AB) and anterior slope (BC) was 37.22±3.87 degrees. 3. In 1 inch opening position, the distance between the summit of condylar head from thestandard point of articular eminence (B) was

One case of Behcet's disease with multiple aneurysms in both common carotid arteries and abdominal aorta is presented with brief review of the literatures. A 26-year-old woman had slowly enlarging pulsatile masses in both sides of neck and recurrent ulcerations in oral cavity and genitalia. One day prior to admission, aphasia, right facial nerve palsy and right hemiplegia suddently developed. Brain CT showed acute infarction in left basal ganglia. Both Carotid Angiography and abdominal Aortography demonstrated mulitple aneurysms in both common carotid arteries and abdominal aorta with organizion thrombi and thromboembolism of internal carotid artery.

Aortopulmonary fistula is an exceedingly rare vascular malformation. It is commonly derived after chest injuly or from complication of chest operation and aortic dissection and congenital aortopulmonary fistula is only several cases combined with Tetralogy of Fallot or aortic stenosis. But a congenital aortopulmonary fistula without any hemodynamic abnormalities was not reported. A 56-year old man with exertional dyspnea was admitted. In an examination on admission, there were no abnomalities. Aortography showed an aortopulmonary fistula that branches from the ascending aorta adjacent to the right coronary artery, running to the main pulmonary artery. Transcatheter coil embolization was performed and he was discharged 7 day after embolization without complication. Exertional dyspnea disappeared and careful follow up has be performed periodically.

OBJECTIVES: Culture of sputum is apt to be contaminated through oral cavity and proximal airway. Therefore, identification of true etiologic agents by sputum culture is not always reliable. In order to differentiate the pulmonary infection from non-infectious disease and to identify the true etiologic agent of acute pulmonary infection, we used PSB(Protected Specimen Brushing) and evaluated the efficacy of PSB. METHODS: In 168 patients with acute febrile illness with pulmonary infiltrations(male 106, female: 61, mean age: 49.5+/-17.6), we performed PSB via a bronchoscope and compared the results along with blood culture and sputum culture. Protected specimen brush was introduced through biopsy channel of bronchoscope and was rotated within the purulent secretions. Tip of the brush was severed with aseptic technique and was immersed in 1cc of Ringer's lactate solution and vigorously mixed for 1 minute. The specimen was submitted for quantitative culture within 15 minutes and was regarded positive culture if colony forming units were above 10(3)/ml. RESULTS: Using PSB for the diagnosis of pulmonary infection, sensitivity was 71.1% and specificity was 84.296. PSB was helpful in identifing true etiologic agent among several potentially pathogenic organisms. Using PSB for the diagnosis of UAP (ventilator associated pneumonia), sensitivity was 72.4% and specificity was 100%. CONCLUSION: Use of PSB can be a helpful method for the diagnosis of pulmonary infection and identification of its etiologic agents.

PURPOSE: This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS: Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test. RESULTS: The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). CONCLUSION: The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.

Furfurol(Furfudol), a new anthelmintics, was administered to 7 adults and 21 children (6-12 years old) in total amounts of 15.6 mg(base) for 1 to 3 days. It has proven to be effective against hookworms. The anthelmintic effect against hookworms with a single dose of 15.6 mg of furfurol was similar to that of a single dose of 2.5 gm of bephenium hydroxynaphthoate. However, when a total of 15.6 mg of the base was given to both children and adult, the side reactions were so mild that the drug can be administered for therapeutic regimens in mass treatment. Minor abdominal discomfort was the only common side effect. This is the primary advantage of furfurol as compared with bephenium hydroxynaphthoate. These results have indicated that furfurol is safe in therapeutic dosage and is an effective agent to treat patients infected with hookworms.

BACKGROUND: The combination of Philadelphia chromosome (Ph) and monosomy 7(-7) was rarely observed in acute lymphoblastic leukemia (ALL). With the results from immunophenotyplc and molecular analysis, Philadelphia chromosome positive ALL with monosomy 7[Ph(+)/-7] has been considered that it may be derived from neoplastic transformation at the pluripotent stem cell level. We compared the clini-cal, laboratory, and hematological findings between 5 cases of Ph(+)/-7 and 5 cases of Ph(+) without monosomy 7 [Ph (+) /N7]. METHODS: During the period from January, 1995 to December, 1996, total 72 cases of ALL were confirmed among 259 cases of hematologic malignancy with bone marrow cytogenetic analysis. Among 72 ALL cases, 5 cases of Ph(+)/-7(monosomy 7 or 7q abnormalities) were compared with Ph only or Ph without monosomy 7(ph(+)/N7] on the hematological, immunophenotypic, other laboratory, clinical findings and event ree survival (EFS) The karyotyping of the bone marrow specimens was analysed byshort-term unsynchronized culture methods such as overnight colcemid treatment and 24 hours incubation following ethidium bromide treatment. RESULTS: The mean age of Ph(+)/-7 was 30.6+/-12.8 years, and it was significantly different from that of Ph(+)/N7 (p=0.009), Four cases of Ph(+)/-7 were classified as ALL L2 subtype, and 2 cases revealed CNS involvements. Immunophenotyping was positive in CD10, CDl9, CD2O, CD22 and HLA-DR. But one case revealed e-B-lymphoid lineage with positivity in CD34, CDl3, and CD33. The response to chemotherapy and EFS was very poor in Ph(+)/-7 group, and the mean EFS was 3.2+/-1.9 months(p=0.014). All of cases showed induction on failure in chemotherapy, relapsed with bone marrow, CNS and extramedullary involvements, and expired due to sepsis. CONCLUSIONS: Ph(+)/-7 ALL had very Poor clinical course with being resistant to chemotherapy and unfavorable prognosis, revealed L2 subtype by FAB classification, and was slightly older in ages compared with Ph(+)/N7 ALL.

For the morphological analysis of DMBA (9,10-diemethyl-1,2-benzanthracene) induced tumor, thirty Sprague-Dawley rats were received 0.1 ml of a 2% paraffin solution of DMBA into the knee joint cavity, which was repeated three times at an interval of 4 weeks. The induced tumor masses were removed at the 12th week after the first injection. Histological and histochemical examinations (H & E, PAS, alcian blue, Van Gieson, prussian blue, reticulin, PTAH stain) and enzyme histochemical examinations (acid phosphatase, alkaline phosphatase, alpha-naphthyl acetate esterase) were performed. The results were as follows: 1) By the 12th week after the first injection of DMBA, the tumor incidence rate was 20 percent. 2) On histological and histochemical examination, most of the induced tumor disclosed the features of the fibrous histiocytoma originating from mesenchymal cells, and the remains sweat gland adenoma and adenocarcinoma originating from epithelial cells. 3) On enzyme histochemical examination, most of the mesenchymal cell-derived tumor cells showed positive reactions for acid phosphatase and alpha-naphthyl acetate esterase, which were similar characteristic features of enzyme stains as shown in the component cells of fibrous histiocytoma.

PURPOSE: High risk women with congenital heart disease decide to get pregnancy is determined by not individual autonomous intention but complex interaction with their physical status and socio-psychological environments. This study tried to the answer to the question. : "What is experience high risk women who have congenital heart disease during transition to parenthood?". METHOD: A micro-ethnographic research method and oral historic research approach were done at the Grown-Up Congenital Heart Disease Clinic in one Korean metropolitan city from July 2002 to September 2003. RESULT: It was discovered that high risk women's experience of transitional parenthood is accounted as the process of lonely and fearful self-accomplishment. Their need for self- accomplishment creates them seek more opportunities to increase enduring abilities for their parenthood. CONCLUSION: We suggest that from the time of beginning of patient's making decisions about becoming pregnant, collaborative efforts must be considered that priority level of patient's needs be reviewed and find appropriate advices for their situation. Special counseling program should be provided to all the prospective parents with understanding their meaning of parenthood.
