PURPOSE: To evaluate the frequently of low ahetenuation area in enhanced CT scans of non-Hodgkin lymphoma(NHL) and to find out if there is any pertinent relationship between this and the histopathologic classification. MATERIALS & METHODS: The authors reviewed CT scans in the newly diagnosed 53 patients with NHL. We defined the-low attenuation area as the one with CT attenuation value lower than that of the muscle, surrounding lesion, or other lymph nodes after contrast enhancement. NHL with the low attenuation areas were correlated with the histopathologic findings according to the classification based on the Working Formulation and the frequency of the lesion was evaluated. RESULT: Of the 53 patients, the low attenuation area was found in 13 patients (25%) at CT. The histopathologic classification could be made in 12 patients, among whom one patient was classified as low grade, six as intermediate grade, and five as high-grade. Concerning the specific cell typing, the diffuse large cell type was most common in intermediate-grade NHL seen in five patients and the large cell, immunoblastic type was most common in high-grade NHL seen ih three patients. CONCLUSION: The authors concluded that the low attenution area within lymphoma is not an infrequent finding at CT, and there was no stastistically significant correlation between this finding and the prognostic grading of the Working Formulation.

The study was undertaken to assess the CT density of the antibiotics solution. CT scan of six antibioticssolution-streptomycin, chloramphenicol, Na-penicillin, ampicillin, kanamycin and cefamezine-in concentration ofabout 33% (approximatly single dose of intramuscular injection) was performed, using plastic syringes. Variousconcentrations of striptomycin, chloramphenicol and Na-panicillin were also examined for evaluation of relationbetween concentration and the CT density of the antibiotics. In addition, relationship between CT number andmathematically calculated effective atomic number and electron density of the antibiotics was evaluated. Theresults are as follows; 1. The CT densities of all antibiotics reveal high density (CT number 80–150) inconcentration of single intramuscular injection dose. 2. CT number of striptomycin, chloramphenicol andNa-penicillin gradually increased with increase of concentration of the antibiotics, producing linear proportionto concentration, effective atomic number and electron density of the antibiotics. 3. Therefore, density ofantibiotics should be included in differential diagnosis when high density on CT scan is observed.

The purpose of this study is to confirm the effectiveness of stay-suture which is commonly used in the procedure of end to end anastomosis, to find out general biomechanical properties of peripheral nerve with gradual stretching and to evaluate the histological difference after breakage of the nerve. The sciatic nerves of adult rabbits were excised and they were grouped by I and II. Group I was composed of 14 normal sciatic nerves and group II, 14 sciatic nerves sutured with 5-0 nylon after transection. They were stretched on the "Instron" universal testing machine at a constant rate of 200mm/min until breakage took place and the results were compared. The mean maximal tensile strength was 13.6N in group I and 2.1N in group II, representing about one seventh value. The mean ultimate tensile strength was 4.2MPa in group I and 0.9MPa in group II, representing about one fifth value. In load-elongation curve of group I, viscoelastic property was noted as all other biological tissues have. The mean modulus of elasticity was 19 in normal sciatic nerves, which is somewhat lower value than other tissues, indicating superior elastic property of peripheral nerves. Transverse histologic examination showed that epineurium lost its continuity earlier than perineurium, implying perineurium is a more resistant structure than epineurium. However, to confirm this, it is thought to be necessary to examine the nerves serially during distraction at each different status. In conclusion, stay-suture provided about one fifth of ultimate tensile stress, implying its usefullness of resisting excessive tension in end to end anastomosis of peripheral nerves. Normal sciatic nerves showed viscoelastic property with mean modulus of elasticity of 19.

Bone grafts are an integral and important aspect of craniofacial reconstruction. Rips, tibia, and iliac bone have traditionally used as donor site but each of these has various problems, however using to the calvarial bone as a donor site has several advantage. These are as follows; there are abundance of material, easy to reach the donor site through coronal incision, minimal pain of donor area, less functional inability, shorter hospitalization, no need of immobilization, hidden scar at donor site, no secondary deformity and appropriate curvature obtained properly selected. From March to December 1987, we experienced three cases of autogenous calvarial bone graft such as congenital saddle nose deformity, fibrous dysplasia on the right side frontal bone, and deviated nose. The results were very excellent without any significant complication. The detail technique of autogenous calvarial bone graft and its advantages compared with the traditional methods of bone grafts are discussed.

A 54-year-old diabetic man presented to the hospital with shock and bradycardia. His initial estimated left ventricular ejection fraction (LVEF) was 15% and the electrocardiogram showed a junctional escape rhythm with a wide QRS complex and no P wave. Intensive supportive therapy was initiated after inserting a pacemaker and starting extracorporeal membrane oxygenation. A myocardial biopsy confirmed acute lymphocytic myocarditis with extensive myocyte necrosis, and cardiac transplantation was planned. However, the patient survived without transplantation after vigorous hemodynamic support for 2 weeks. After discharge, he had limited activity for 4 months due to dyspnea caused by a reduced systolic heart function (LVEF, 21%) with a junctional escaped beat. His systolic function recovered markedly 6 months after stopping the hemodynamic support, with the presence of a P wave and narrowed QRS complex.

To evaluate the sensitivity and specificity of transthoracic fine needle aspiration cytology(TFNAC) in the preoperative diagnosis of pulmonary nodules, a retrospective analysis was carried out on a consecutive series of 200 TFNACs. They included 186 primary malignant tumors, 66 squamous cell carcinomas, 65 adenocarcinomas, 36 small cell carcinomas, 7 large cell carcinomas, 4 carcinoids, 8 others, 9 metastatic tumors, and 5 benign tumors. On cytohistologic correlation of malignant pulmonary tumors, the pro- cedure had a sensitivity of 97.3% and a specificity of 100%. A 86.6% correct correlation between the cytologic and histologic diagnoses was achieved. Five out of the 7 undifferentiated large cell carcinomas, 10 out of the 65 adenocarcinomas, 2 out of the 36 small cell carcinomas, and 2 out of the 66 squamous cell carcinomas were turned out to be mistyped in cytologic diagnosis. We concluded that TFNAC is a highly sensitive and specific preoperative diagnostic procedure in the investigation of patients with discrete pulmonary nodules in whom the specific cell type of the malignant neoplasm has important implications in treatment modality and prognosis.
