PURPOSE: We performed this study to evaluate the incidence of thoracic inlet pathologies. We also evaluated the extension of the thoracic inlet lesions to neck and/or mediastinum to determine anatomic connections between neck and mediastinum. MATERIALS AND METHODS: we evaluated chest radiographs and CT scans of the 41 patients with various pathologies involving this region. RESULTS: Thyroid lesions and malignant lymphomas were the most common pathologic lesions in this region (54%). Thoracic inlet lesions extending from mediastinum included various pathologies including thymic lesion (n=8) in the anterior mediastinum, neurogenic tumor(n=2) in the posterior mediastinum and malignant lymphoma(n=5) in the multiple compartment. Thoracic inlet lesions extending from the neck(n=9) were mostly thyroid lesions(n=8) arising in the visceral space of the neck. Thoracic inlet lesions(n=11) involving both neck and mediastinum were thyroid lesions, abscesses, thymic lesion, malignant lymphomas and cavernous hemangiomas. Thyroid lesions and cavernous hemangiomas showed remarkable enhancement on post contrast enhanced CT. Teratoma contained fat density and Two cases of abscesses contained air density. CONCLUSION: Thyroid lesions and malignant lymphomas were the most common pathologies in the thoracic inlet. There was anatomic connection between neck and mediastinum through the thoracic inlet. CT was valuale in evaluation of the location, extension, and density of the mass for the differential diaguonis of the thoracic inlet lesions.

In order to compare the changes of dentofacial skeleton, teeth and soft tissue profile in Class I malocclusion patients treated with and without extraction, cephalometric radiographs were taken in 22 female patients as extraction group and 23 female as nonextraction group who were treated in the Department of Orthodontics in Chonnam National University Hospital. The results were as follows. 1. At the beginning of treatment, average age was 19.0 years in extraction group and 15.9 years in nonextraction group. Duration of treatment was 2.8 years in extraction group and 1.7 years in nonextraction group. 2. Before treatment, there were significant difference between 2 groups in the amount of protrusion and proclination in upper and lower central incisor and lower lip protrusion. After treatment, these differences were decreased. 3. In comparison before and after treatment in extraction group, upper and lower central incisor protrusion and lower lip protrusion were significantly improved. In nonextraction group, retrusion and improvement of inclination of upper and lower central incisor were not found.

A clinical observation was performed on 154 cases of chronic prostatitis in the Department of Urology, National Seoul Hospital from January 1981 to March 1982. The results are as follows: 1. 121 cases or 78.4 percent of the cases were observed among the ages between 20 to 40 years are more than one half of these cases were seen between the ages of 26 to 35 years. 2. Previous diseases were Non-gonococcal urethritis on 82 cases (53.2%), Gonococcal urethritis on 45 cases(29.2%) and previous prostatitis on 15 cases (9.7%). 12 cases (7.8%) were free of previous diseases. 3. Most frequently observed symptoms consisted of those of mild chronic urethritis such as morning drop, urethral discomfort, perineal discomfort and frequency. 4. In microscopic findings of wet smear of the prostatic secretion, 125 cases (81.2%) showed W.B.C. more than10/H.P,F. 29 cases (18.8%) were within normal limit. 5. In 125 cases in which prostatic gram stain was done, microorganisms were gram (+) cocci on 26 cases (20.8%),gram (-) bacilli on 12 cases (9.6%) and gram (+) bacilli on 10 cases (8.0%). No microorganism were on 77 cases (61.6%).

Bone imagings have played important role in early detection of acute osteomyelitis. In acute osteomylitis, bone scan findings precede the appearance of bone change on radiograph. Also, recent studies have reported accuracies of bone scan in diagnosis of osteomyelitis ranging from 84% to 100%. But, in above datas, bone scan reading were only qualitative studies. So we have reviewed Technetium-99m labelled methylen dipho sphonate(99mTc-MDP) scan on 21 patients who had been diagnosed acute osteomyelitis by clinical symptoms, blood culture, pus culture and operative findings from January, 1984 to September, 1985. The purpose of this study is to establish the quantitative study of bone scan using computed pixel counting method. The 21 cases were classified into group I and group II according to initial radiographic findihgs. The group I showed normal radiographic finding or soft tissue swelling without osseous change. The group II showed osseous change. The results obtained were as follows: 1. We obtained positive bone scans in the all cases which were confirmed acute osteomyelitis. 2. We experienced diagnosis of acute osteomyelitis by bone scan which was confirmed as early as 48 hours after onset of clinical symptom. 3, In group I, the average uptake ratio of 99mTc-MDP was 3.22±0.82 ranging from 2.20 to 4.80. 4. In group II, the average uptake ratio of 99mTc-MDT was 6.20±2.27 ranging from 4.00 to 9.40. (p <0.001).

Nine species of genus Ganoderma different in cultural characteristics each other were separated by histo-anatomical differences. Differences among the species and geographic distribution of G. lucidum were also analyzed to provide the criteria for the classification of Korean cultivation or wild type strains. Korean cultivation and wild type strains were quiet different from other species as well as Taiwan and North American G. lucidum strains in histo-anatomical traits of Ganoderma. Pore color of Korean G. lucidum strains was less brown than those of Taiwan and North American strains. Shapes of pores were round or circular in Korean strains but ellipsoidal or angular in Taiwan or North American strains. Pore numbers of Korean strains were more than those(4~6/mm) of Taiwan or North American strains. Hardness of the pileus of Korean strains was much more than that of Taiwan or North American strains. Such characteristics of Korean strains were different from those of other species of Ganoderma. Korean G. lucidum strains could be classified into the other group because they had many different traits in growth characteristics of fruiting bodies and histo-anatomical characteristics from those of Taiwan or North American G. lucidum and other species of G. lucidum complex.

Twenty-two cases of idiopathic myocardiopathy were observed during the period of 1962 to 1971 and follow up clinical study was made in 5 cases. The criteria of diagnosis was based mainly on exclusive diagnosis in etiology unknown marked cardiomegaly. 1) Male and female ratio of idiopathic myocardiopathy was 1.1:1 and age of onset were distributed from first decade to fifth decade with similar number of cases. 2) Cardinal symptoms were dyspnea, palpitation, chest pain and cough. Common physical findings were protodiastolic gallop (in 2 cases), moist rales (in 3 cases) and hepatomegaly(in 3 cases). 3) Laboratory findings were normal except elevated T.T.T. in one case. 4) Electrocardiogram were abnormal in all cases. There were 3 cases of left ventricular hypertrophy, 3 cases of non-specific ST-T changes and one case of first degree A-V block, intraventricular conduction defect, abnormal Q wave and low valtage, respectively. 5) After medical treatment, symptoms were improved in 4 cases but heart size was reduced in only one case and E.C.G. abnormalities were unchanged in all cases.

BACKGROUND: The Fas antigen is a cell surface molecule that mediates apoptosis in many cell types. Matsues group indicated that keratinocytes constitutively express the Fas antigen and apoptosis was induced only on pretreatment with interferon-r (IFN-y) in cultured normal human keratinocytes (NHK). OBJECTIVE: We undertook this study to determine the induction of apoptosis by Fas antibody alone and/or in combination with IFN y, IL-1a in normal human keratinocytes (NHK) and transitional epithelioma cell lines (KB cell) which had lower levels of intracellular IL-1 receptor antago- nists (IL-1ra ). METHODS: We used cultured NHK and KB cells. Each cell was treated with IFN-r, IL-la and Fas antibody for induction of apoptosis. For quantifying the apoptosis, index fluorescent DNA- binding dyes were used. Result: Fas antibody alone could induce apoptosis not only in KB cells but also in NHK cells. The combination of Fas antibody and IFN-r enhanced the induction of apoptosis in NHK and KB cells. The IL-la alone could induce apoptosis only in KB cells which had relatively small amounts of IL-1ra compared to NHK. CONCLUSION: Our result may indicate that Fas antigen in human keratinocytes can regulate normal epidermal cellular differentiation and proliferation.
