The purpose of this study w-s to predict the respose to the chincap therapy from the initial cephalometric measurements and to obtain the indication of chincap therapy. 40 patients selected for this study were classified into two groups by the occlusal stability after completion of permanent dentition and the iiu4n ovement of facial profile, after chincap therapy. One was g response group which consisted of 25 children and the other was poor response group with 15 patients. Various measurements of the craniofacial structure in the initial lateral cephalogram were calculated and analyzed by t-test and discriminant analysis. The results were, as follows 1. Good response group had more horizontal growth pattern in initial stage of treatment, and the contributing measurements were Bjork sum, anterior-posterior facial height ratio, gonial angle, lower gonial angle and occlusal plane to AB plane angle. 2. The critical points and predictive values of the influential skeletal measurements were calculated. 3. The discriminant function was obtained from three. major influential measurements; Bjork sum, gonial angle and occliml plane to AB plane angle, and this function could discreminate correctly in 85% of this samples.

BACKGROUND: Dopamine is an inotropic agent that is often selected for continuous infusion. For hemodynamic stability, the rate of infusion is controlled in the range of 5-15 µg/kg/min. This study aimed to compare the time intervals from the administration of dopamine to the onset of its hemodynamic effects when dopamine was administered through three different peripheral veins (the cephalic vein [CV], the great saphenous vein [GSV], and the external jugular vein [EJV]). METHODS: Patients in group 1, group 2, and group 3 received dopamine infusions in the CV, GSV, and EJV, respectively. A noninvasive continuous cardiac output monitor (NICCOMO™, Medis, Ilmenau, Germany) was used to assess cardiac output (CO) and systemic vascular resistance (SVR). Six minutes after intubation, baseline heart rate (HR), systolic blood pressure (BP), diastolic BP, mean arterial pressure (MAP), CO, and SVR values were recorded and dopamine infusion was initiated at a dose of 10 µg/kg/min. Hemodynamic changes at 0, 4, 8, 12, and 15 minutes postinfusion were recorded. RESULTS: No statistically significant differences were observed among the three groups with respect to the rate of hemodynamic change. In all groups, systolic BP, diastolic BP, MAP, and SVR tended to increase after decreasing for the first 4 minutes; in contrast, HR and CO decreased until 8 minutes, after which they tended to reach a plateau. CONCLUSIONS: For patients under general anesthesia receiving dopamine at 10 µg/kg/min, there were no clinical differences in the effect of dopamine administered through three different peripheral veins.

Computerized Tomography is now well established and important noninvasive method of diagnosting mediastinal mass lesions because of its superior imaging of their size, location and internal composition. Authors analyzed and present CT findings of 30 surgically proven mediastinal tumors and cysts that were studied and treated at the Yeungnam University Hospital during recent 6 years. The most common tumor was thymoma (9 cases), and teratoma (6 cases), lymphoma (6 cases), bronchogenic cyst (4 cases), neurogenic tumor (4 cases), pericardial cyst (1 case) were next in order of frequency. There were 5 cases of thymoma showing homogenous solid density mass, 2 cases were malignant thymoma and myasthenia gravis was present in 2 cases. A case of thymolipoma and a case of thymic carcinoma were included. All teratomas were cystic masses but pathognomonic fat, and calcified density were seen only in 4 cases. 5 cases were located in anterior mediastinum and 1 case was in posterior mediastinum. Lymphoma (3 Hodgkin's and 3 non-Hodgkin's) appeared as irregular lobulated mass in anterior mediastinum. Neurogenic tumor (2 ganglioneuroma and 2 neurilemmoma) appeared as homogenous density mass located in posterior mediastinum. Among the 4 bronchogenic cysts, 2 were located in retrotracheal area, 1 was located in subcarinal and 1 was in parathoracic area. One case of pericardial cyst was oval shaped cystic mass located in left pericardiac border.

The results of allelic frequency of polymorphic loci in the short arm of chromosome 3 in normal Koreans are shown using a polymerase chain reaction (PCR) based restriction fragment length polymorphism analysis on blood samples of 20 males and 20 females without any tumor or hereditary diseases. The allelic frequency of two loci, D3S2 (MspI) and D3F15S2 (Hind III ) was quite different between renal cell carcinoma in Koreans and Caucasians, but THRB (MspI) locus was similar This suggests the importance of determining specific loci to Koreans. The study of tumor suppressor gene on these genetic loci due to D3S2 (MspI) and THRB (EcoRI) loci showed high constitutional heterozygosity, contrast to D3F15S2 (Hind III), THRB (BamHI) and THRB (MspI) loci where low constitutional heterozygosity were seen. Therefore, the study of tumor suppressor gene should be directed to investigate. This study showed the allelic distribution of Koreans differing from Caucasians and the genetic locus with the high frequency of heterozygosity among the polymorphic loci comparable to Koreans were due to the difference of heterozygosity frequency according to genetic loci. Therefore, the author thinks that the need for the detection of specific genetic loci for Koreans to study the correlation among many cases for classifying the tumorigenesis and active research should be initiated to find other genetic locus related to multi-step tumorigenesis.

Eosinophilic pustular folliculitis was first reported by Ofuji and Ogino in 1970, which is characterized by eruptions of aggregated pustules containing numerous eosinophils and by blood eosinophilia. Most cases were confined to Japan and the authors first observed two cases of typical eosinophilic pustular folliculitis in Korea. In case 1, the skin lesions were grouped uniforrn follicular papules on the erythematous base which intermingled with vesicopustules at the edge of the patches on the mandibular area, the neck and the anterior chest having tendency to central healing and peripheral extension like dermatophytosis. In case 2, the skin lesiens vere groupod uniform follicular papules of 1-2mm in diameter to form patches of 5-10 cm in diameter on the back, the a,nterior chest and the upper examities, some of which were topped with pustules or crusts. In both cases, blood eosinophilia were prominent and the histopathclogic findings showed dermal infiltration and abscesses of predominently eosinophilic leukocytes localized to follicles. The authors made the diagnosis of eosinophilic pustular folliculitis from the characteristic clinical and histopathologic findings.
