Teratoma of the heart is very rare and occurs mainly in children. A 44-year-old male patient was admitted due to foreign body sensation on throat and chest discomfort for a month. Chest CT, MRI and trans- thoracic and transesophageal echocardiographies showed 12x10 cm sized cystic mass with septataion and solid nodules, combined with pericardial and pleural effusion. Excision of the tumor was done and the pathologic diagnosis was mature cystic teratoma arising from pericardium.

BACKGROUND: The more vital organ blood flow during cardiopulmonary resuscitation (CPR), the more successful outcome. The worldwide CPR drug of choice, epinephrine also has some limitations and is often challenged by another catecholamine drug. This study was designed to compare the effects of epinephrine with those of vasopressin and epinephrine mixture on cerebral no-reflow during closed-chest CPR in a rabbit model of ventricular fibrillation. DESIGN: Prospective, randomized, experimental study. SETTING: University research laboratory. SUBJECTS: Domestic rabbits,3 to 6 months of age InteNentions : Four rabbits were randomly allocated to receive only 0.020 mg/kg of epinephrine(group 1) and another four rabbits were received both 0.020 mg/kg of epinephrine and 0.8 U/kg of vasopressin after 5 mins of cardiac arrest(group 2). MEASUREMENTS AND MAIN RESULTS: Carotid arterial blood flow and arterial gas analysis were showed no statistical difference between two groups but in the points of cerebral no reflow area and fluorescence exposure time, there were significant differences(group 1,5.15+/-.45%, group 2, 6.38+/-.54%, p=.029/ group 1; 29.65+/- 17.09 seconds, group 2;17.98+/- 18.75 seconds, p=.014). CONCLUSIONS: In cardiac arrest there is some synergistic effect with epinephrine and vasopressin mixture on cerebral no-reflow phenomenon.

The purpose of this study was to compare the casting problem and corrosion behavior in two types of HL Hexed abutments of the Steri-Oss system : gold/plastic coping and gold coping. The anodic Polarization behavior, the galvanic corrosion between abutments and Type III gold alloys, before and after casting were analyzed, and the crevice corrosion of casting samples was analyzed with the CPPT test and the SEM. The results are as follows ; 1. Anodic polarization behavior of samples ; Before casting, gold/plastic coping and gold coping was shown to have a similar corrosion patterns. TypeIII casting gold alloy was shown to have a lower corrosion potential and passivation film. Corrosion potential of the case of gold/plastic coping after casting was higher than that of gold coping, but the region of passivation film for gold/plastic coping was smaller than that of gold coping. 2. Galvanic corrosion behavior of samples ; Contact current density between casting gold alloys and gold/plastic before casting was higher than that between gold coping and casting gold alloy. Galvanic corrosion of samples after casting was shown to have similar contact current density. 3. Crevice corrosion behavior of samples ; Crevice corrosion resistance of casting sample using gold coping was lower than that of casting sample using gold/plastic coping, and a severe corrosion pattern was observed at the abutment-casting gold alloy interface by the SEM.

Recently, various implant cylinders were supplied, especially received gold cylinders, cast cylinders produced from premade gold and plastic cylinders and plastic cylinders. This study measured and compared precise fit produced when using conventional gold and plastic cylinders. The comparative fit of lapped and non-lapped castings made from plastic pattern was examined. The implant/abutment interface fit was evaluated by scanning electron microscopy(SEM) for each of four cylinders. The following results were obtained: 1. The case of plastic cylinder showed 9.67+/-1.50micrometer gap Steri-Oss fixture was connected. 2. The case oflapped casting made from plastic cylinder showed 3.01+/-2.81micrometer gap when Steri-Oss fixture was connected. 3. The case of gold/plastic cylinder showed 9.80+/-1.68micrometer gap when Steri-Oss fixture was connected. 4. The case of gold cylinder showed 5.47+/-2.43micrometer gap when Steri-Oss fixture was connected. 5. In case of each cylinder which was connected with Steri-Oss fixture, the size of gap was showed less in the order of the case of gold/plastic cylinder, the case of plastic cylinder, the case of gold cylinder and the case of lapped casting made from plastic cylinder. As results of this study, the use of premade gold cylinder offers an advantage over plastic patterns in precise fit. When plastic patterns are used, polishing of implant cylinder components should provide precise fit.

BACKGROUND: Wheezing which is defined as a continuous sound with a musical quality is commonly auscultated in patients with chronic obstructive airway diseases. The correlation between wheezing and airway obstruction is unclear. OBJECTIVE: This study was designed to evaluate the relationships among wheezing, severity of airway obstruction, and pulmonary function tests. METHOD: Forty-one subjects were examined by the same observer. Wheezing during normal breathing and maximal forced exhalation, was auscultated respectively. Posterior lung bases were auscultated bilaterally with the seated patient taking repeated inspiratory capacity breaths through an open mouth. To quantify wheezing intensity, a regional score was assigned for each area after a minimum of 3 breaths, according to the following scale: zero, no wheezing heard: one, faint or intermittent wheezes: two, moderate wheezing during every expiration: three, loud wheezing during every expiration. The lung function tests by standard pneumotachograph were performed by skilled technicians. RESULTS: Wheezing was auscultated more in forced exhalation than in normal breathing in patients with asthma and COPD [8/9(88%) vs 1/9(11%), p<0.01 ll/15(73%) vs 1/15(6%), p<0.05)]. Forced expiratory wheezes group (n=25) compared to no wheezes group (n=16) had significantly lower FEVl (75+-5.8% vs 95.6+-6.6%, p<0.05). Compared to no wheezes group, the group with forced expiratory wheezes had lower FEV1 and FEV1/FVC (50.4+- 21.3% vs 81.15+-27.7%, 70.4+-22.4% vs 92.5+-19.3%, respectively, p<0.05). Bronchial asthma compared with COPD tended to have higher wheezing scores (Wheeze scores Bronchial asthma 3.5 vs COPD 2.4, p=0.08). Wheezing scores were correlated to FEV1 (normal breathing: r=-0.35, p<0.05: forced exhalation: r=-0.45, p<0.05), but no differences were found in wheezing incidence according to severity of airway obstruction. CONCLUSION: These findings suggest that wheezing on maximal forced exhalation may be a useful physical indicator for evaluating the severity of airway obstruction.

Genus of aspergilli are ubiquitous saprophytic molds in nature, which are recognized about 700 species, at least eight are pathologic for human. Pulmonary aspergillosis is rare disease, most frequent presenting as secondary invasion, and aspergillosis of the nasal cavity is the most common sites of the extrapulmonary aspergillosis. Predisposing factors for pulmonary aspergillosis are chronic lung disease, tuberculosis, antibiotics, cytotoxins and neoplasia, hematologic disorders, and histoplasmosis etc. Authors have experienced 10 cases of pulmonary aspergillosis and a case of aspergillosis of nasal cavity in Dept. of Pathol. Chosun univ. hospital and christian hospital from Feb. 1981 to July 1984. Patient of pulmonary aspergillosis are received surgical resection and survived well without complications.

Toxic epidermal necrolysis(T.E.N.) is a toxic erythema of the skin that undergoes epidermal necrolysis and peding so that it appears to have been scalded. There seem to be two basic form of T.E.N. In children, the deavage of the epidermis that results from an acantholytic-dyskeratotic cytolytic process is in the malpighian or granular layer and is usually induced by a staphylococci toxin. In adult, it is characterized by a full-thicknees cytolytic cleavage of skin above the basal layer and is usually precipitated by a drug. The authors observed a 17 year-old male with T.E.N. He began to notify the erythematous skin lesion with burning sensation on the whole body surface at 12 hours after oral administration of some drugs for common cold and developed the characteristic flaccid bullous and denuded lesions with tenderness within next 20 hours.

Tatrate resistant acid phosphatase (TRAP) has been widely used as histochemical marker to identify osteoclast in studies of bone metabolism. However, the value of TRAP as an osteoclast marker is still in discussion. Authors isolated and characterized the cells from synovium of 6 patients of sero-positive rheumatoid arthritis and 4 patients of osteoarthritis, and observed the activity of acid phosphatase (AP) and TRAP. The activity of TRAP was negative in cell cultures in early phase, but the activity of TRAP was increased with time, and at one week the activity of TRAP was as strong as that of AP. If the cultured tissue contained bone, there were observed TRAP positive mononuclear cells and giant cells even in early phase of cultures (1 day, 3 day), and the phenotype of these cells were same as that of osteoclasts and osteoclast precursors by immunocytochemistry. In conclusion, the activity of TRAP was positive in cultured macrophage. TRAP is not a specific marker for osteoclast, and its use for the identification of osteoclast seems meaningful only in the early stage of cell culture.

Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.
