An accurate and relatively simple method for estimating the amount of acute blood loss is essential in the hemorrhagic shock patients. Conventional physiologic parameters, blood pressure, pulse rate and CVP, could not serve for evaluation of the adequate oxygen transport in the tissue. Pulmonary artery catheter is a best tool for evaluating the cardiopulmonary function and the oxygen transport system, and mixed venous oxygen saturation(SvO2) monitoring have made a great advances for early detection of cardiovascular dysfunction and the changes in peripheral tissue oxygenation. But pulmonary artery catheterization is complicated procedure in emergency setting. Although the central venous oxygen saturation(ScvO2) cannot completely replace the SvO2 value, it has a close relation with SvO2 change in variable clinical situations. We testify the usefulness of ScvO2 monitoring in 24 patients of the hemorrhagic shock. Initial resuscitation was performed with ATLS standard and continuous ScvO2 was monitored. Systolic blood pressure and pulse rate were recorded for one hour from initial resuscitation in each 15 minutes. Nineteen patient was traumatic hemorrhagic shock and five was non traumatic. Twelve of 19 patients was blunt trauma, and remains were stab in injury mechanism. Mortality rate was 29.2%. Initial ScvO2 of nonsurvivor was 43.6%, and 51.3% in survivor groups(p>0.05). In the group of stab wound and non-traumatic hemorrhage, the ScvO2 was gradually increase by time. But ScvO2 in survivors of blunt trauma was increased first 30 minutes and decrease afterthen. Continuous monitoring of ScvO2 may by partly useful in resuscitation for hemorrhagic shock. It is more valuable in the blunt trauma than in the penetrating injury or non-traumatic hemorrhage.

Angiogenesis is essential for the growth of solid tumors. Microvessel counts, which represent a measure of tumor angiogenesis, have been correlated with the overall survival of patients with a variety of malignancies. However, the significance of angiogenesis in renal cell carcinoma remains controversial. To determine whether angiogenesis correlates with prognosis of patients with renal cell carcinoma, we counted the microvessels within the primary tumors and compared their numbers with patients' prognosis. Tumor specimens from 42 patients were investigated. Microvessels were stained with anti-CD34 and anti-factor VIII-related antigen monoclonal antibodies. Significant correlation between microvessel counts for two antibodies was observed (r=0.875, p<0.01), although microvessel counts for CD34 were approximately two times higher. Microvessel counts were higher in clear cell than in non-clear cell carcinoma (p<0.05). These results suggest that immunostaining with anti-CD34 antibody may provide a more sensitive and accurate measure of tumor angiogenesis. There was no correlation between microvessel counts and nuclear grade, or TNM stage. In univariate analyses, nuclear grade and TNM stage were significantly associated with patient survival (p<0.01). But further studies on tumor angiogenesis of renal cell carcinoma are needed before it can be adopted as a prognostic marker.

6.Three dimensional finite element analysis of the phenomenon during distal en masse movement of the maxillary dentition.
Korean Journal of Orthodontics 1998;28(4):563-580
This study was designed to analysis the displacement and stress distribution of individual tooth by orthodontic force during distal en masse movement of the maxillary dentition. In this study, three dimensional finite element analysis was used. Author made the finite element model of maxillary teeth, periodontal ligament, alveolar bone and bracket with anatomic and physiologic characteristics on computer. Author analysed and evaluated the displacement and stress distribution of individual tooth when extraoral force, Class II intermaxillary elastics, ideal arch wire, MEAW and tip back bend were used for distal en masse movement of the maxillary dentition. These analyses were also applied in the case of the maxillary second molar were not extracted. Author compared the results of the cases which maxillary second molar were extracted or not. The results were expressed quantitatively and visually. Author obtained following results, 1. When anterior headgear was applied, the posterior translation, posterior tipping, and vertical displacement of teeth were produced more in the anterior segment of the dentition. 2. When Class II intermaxillary elastics were applied in the ideal arch wire, the teeth disp acement were usually produced in the anterior segment. But when tip back bend were added in the ideal arch, the orthodontic force produced by elastics were transmitted to the posterior segment. As increasing the tip back bend, posterior translation and lingual tipping of anterior teeth were decreased, posterior translation and tipping displacement of posterior teeth were increased, and extrusion of anterior teeth by Class II elastics were decreased. 3. When MEAW and Class II elastics were applied, the teeth movement were similar with the case of ideal arch wire and Class II elastics, but more small and uniform teeth displacement were produced. Compared with the ideal arch wire, posterior tipping of the posterior segment were more produced than lingual tipping displacement of the anterior segment. 4. When the maxillary second molar without orthodontic appliance existed, the displacement of maxillary first molar were decreased.

BACKGROUND: Genus of Aspergilli are ubiquitous saprophytic molds in nature, but its change from a saprophytic fungus to a pathogenic organism has occurred since the use of various antibiotics. The fungus affects the chronically ill and debilitated population. Recently frequency of the fungal infection is increasing in Korea with abuse of antibiotics and glucocorticoids. METHOD: We analyzed medical records of 52 patients with pulmonary aspergillosis seen at Hanyang University Hospital from 1980 to 1994. The results were as follows; RESULTS: 1) Ages ranged between second to eighth decades with majority(50%) in the fourth to fifth decades. The male to female ratio was 1.1:1. 2) Hemoptysis and productive cough, the leading symptoms, occurred in 42.3% and 25% respectively. 3) On chest X-ray fingings, the characteristic 'fungus ball' pattern were observed in 53.8% of the 52 cases. 4) Sputum culture for aspergilli were positive in 21.6% of the cases. We performed foe needle aspiration in 22 patients and the diagnostic yield was 100%. 5) Thirty-six patients had history of treatment with antituberculous drugs under diagnosis of pulmonary tuberculosis for an average of 27.3 months. But sputum analysis for acid-fast bacilli were positive in 5.6%(2cases of 36cases), and postoperative pathologic findings showed that 38.9% (12 cases of 28cases) were combined with tuberculosis. 6) Right upper and left upper lobes were predominantly involved(34.6% and 19.2% respectively) and lobectomies were performed in 21 cases. 7) Underlying diseases were present in 47 cases and 48.9% of them were pulmonary tuberculosis. CONCLUSION: These results showed that pulmonary aspergillosis usually develops in patients with open cavitary pulmonary tuberculosis. And we must consider the possibility of pulmonary aspergillosis in a patient with hemoptysis and cavitary lung lesion.

The authors made an attempt to classify the supracondylar extension-valgus fracture according to the direction and location of the fracture line based on the radiographic manifestation. This new classification helps to dictate the model of treatment, possible sequence of reduction and the causes of deformity of the elbow after treatment. During the last 12 years of this study, 200 supracondylar fractures of the humerus were treated in the Kyung Hee University Hospital. Of the cases 82 were extension-valgus fractures. The results were as follows: 1. The supracondylar extension-valgus fracture were classified into 5 types: Type I: fish-tail fracture (14 cases) Type II : obtuse fish-tail fracture (27 cases) Type III: oblique fracture (16 cases) Type IV: oblique fracture with comminution of lateral column (14 cases) Type V: Transverse fracture (11 cases) 2. The displacement of the distal fragment in the fish-tail fracture is severe but it can be reduced easily by manipulation. Once reduction has been obtained, the fracture is stable and maintained by a long arm cast with acute flexion of the elbow alone. There is no need of percutaneous pinning. Among 14 cases of type I fracture there was no cubitus varus deformity. 3. The line of the obtuse fish-tail fracture lies distal to fish-tail fracture. This is unstable so it is necessary to percutaneous pinning. 4. The oblique fracture is produced by the hyperextension of the elbow and degrees of the obliquity of the fracture line were 12 to 20 degrees (Av. 14 degrees). The valgus angles in opposit elbows were 9 to 25 degrees (Av. 16 degrees). The forearm must be pulled into valgus position during the reduction of the fracture. 5. Type IV fracture occures under 4 years old, and more commonly in girls. This is unstable, so it is necessary to percutaneous pinning.
