The ankle is a complex structure supporting the entire musculoskeletal system during standing and walking. The injuries to the ankle joint result in a severe functional disturbance because of complex anatomical characteristics around the ankle joint. 69 patients(72 cases) of the ankle fracture that were treated in Orthopedic Dept. Chonbuk National University Hospital from Jan. 1979 to Dec. 1983 were analized in clinical and radiological aspects. The following results were obtained: 1. Among the 69 patients, male was 54 and female 15 with ratio of 3.5: 1.The average age was 32. 2. Main cause of fracture was traffic accident(58%). 3. The musculoskeletal system was injured most frequently associated with the ankle fracture(66%). 4. According to the ankle fracture classification, the most common type was Pronation-external rotation type in Lauge-Hansen classification, and the type C in Weber classification. 5.The average duration of cast immobilization was 8.8 weeks in closed reduction and 7.4 weeks in open reduction. 6. The lateral malleolar fracture involving the distal tibiofibular syndesmosis was very important in ankle stability so accurate anatomical reduction by internal fixation was necessary for satisfactory functional results. 7. In clinical and radiological analysis, the better results were obtained from open reduction.

Endodernal sinus tumors(EST) are generally recognized as a germ cell tumors with extraembryonicdifferentiation that resemble the endodermal sinus of the rat placenta. Like other germ cell tumors the primaryEST may either occur in the gonads or in specific extragonadal sites. CT is the most accurate study in delineatingthe extent of primary and metastatic lesions particularly in the pelvis. Recently authors experienced six cases ofthe pathologically proven extragonadal endodermal sinus tumors in children and retrospectively analyzed theradiological findings including the CT. The results were as follows: 1 Of the 6 cases of extragonadal EST, theprimary lesion presented in the sacrococcygeal region in 5 patients and liver in one patient. 2. There were 4females and 2 males. Of the sacrococcygeal lesions 3 were females and 2 were males. 3. The age of presentationranged from 9 months to 3 years of age(mean age=21 months) 4. Conventional radiographic study of thesacrococcygeal lesion showed presacral, retrorectal soft tissue mass without calcification which extended into thebuttock. CT revealed well circumscribed enhancing soft tissue mass with irregular central low density areas. 5.Primay EST of the liver revealed ill-defined inhomogeneous mixed echogenic mass( ultrasound) and ill-defined lowdensity mass(CT). Angiography showed hypervascular mass with areas of necrosis and no evidence portal veininvasion. A-V shunting was not present. 6. Reginal lymph node metastasis was present at the time of diagnosis in 2cases of sacrococcygeal EST. 7. Local recurrence of tumor was noted in 2 patients with sacrococcygeal lesion aftersurgery and chemotherapy.

PURPOSE: Diffuse panbronchiolitis(DPB) is a chronic inflammatory airway disease of unknown causes mainly affecting the respiratory bronchioles and the more proximal bronchi. Findings on chest radiographs and high-resolution CT(HRCT) are well known and Akira classified HRCT findings of DPB into four types. Purpose of this study is to evaluate the relationship between findings of HRCT and PFT. METHODS AND MATERIALS: We retrospectively analyzed the chest radiographs and HRCT images of eleven patients with DPB and compared CT classification with pulmonary function test. RESULTS: Chest radiographs usually showed small nodular opacities throughout the both middle and lower lungs. The HRCT findings of DPB were centrilobularly distributed small nodular densities, branching linear densities contiguous with small round densities, dilated and thickened peripheral and central airways including bronchioles. More than one CT type by Akira's classification, usually two or three types, were found in nine patients. There was good correlation between CT types and FEV1%(p<0.05), CT types and FEV1/FVC (p<0.05) respectively. CONCLUSION: HRCT seems to be more useful for diagnosis and disease progression of DPB as compared with the chest radiographs or clinical stage such as pulmonary function test.

PURPOSE: The purpose of this study was to determine the role of CT and MR imagings in the diagnosis aortic dissection and differentiation between the true and false lumen. MATERIALS AND METHODS: We retrospectively studied forty patients with aortic dissection(AD) diagnosed imagings or surgery. Of the forty patients, 19 were examined with only CT, 14 with CT and MR, and 7 with MI~: Our points of view were(1) the classification of AD according to configuration of intimal flap by cross-sectional imaging, (2) differentiation between the true and false lumens, (3) the course of the false lumen, and (4)! detectability of the origin of major branch vessels of the abdominal aorta. RESULTS: The classification by corss-sectional imaging were crescentic(65%), circumferential(15%), flat(12%), and irregular(8%) type, in which false negative diagnosis was made in 1 case of crescentic and circumferential type, respectively. In 2 case of flat type and 1 case of irregular type, the differentiation between the true and false lumen was impossible with CT. The course of the false lumen in descending thoracic aorta revealed countrclock wise rotation(66%), clockwise rotation(5%) or fixed(29%) apperance. MR imaging was superior to CT in the detection of the origin of major branch vessels of the abdominal aorta. The determination of the origin of major branches of abdominal aorta arising from the true and false lumen were impossible in 2 cases in which only CT was done. CONCLUSION: Diagnosis of crescentic and circumferential types of AD with narrow and thrombosed false lumen was problematic in both CT and MR with no difference of diagnostic accuracy between the two modalities. The differentiation between the true and false lumen was difficult in flat and irregular types with only CT. Therefore, when surgical treatment is considered as in type B aortic dissection, MR imaging is recommended in order to determine the origin of major branch vessels.

Beta-lapachone (beta-Lap; 3,4-dihydro-2, 2-dimethyl-2H-naphthol[1, 2-b]pyran-5,6-dione) is a novel anti-cancer drug under phase I/II clinical trials. beta-Lap has been demonstrated to cause apoptotic and necrotic death in a variety of human cancer cells in vitro and in vivo. The mechanisms underlying the beta-Lap toxicity against cancer cells has been controversial. The most recent view is that beta-Lap, which is a quinone compound, undergoes two-electron reduction to hydroquinone form utilizing NAD(P)H or NADH as electron source. This two-electron reduction of beta-Lap is mediated by NAD(P)H:quinone oxidoreductase (NQO1), which is known to mediate the reduction of many quinone compounds. The hydroquinone forms of beta-Lap then spontaneously oxidizes back to the original oxidized beta-Lap, creating futile cycling between the oxidized and reduced forms of beta-Lap. It is proposed that the futile recycling between oxidized and reduced forms of beta-Lap leads to two distinct cell death pathways. First one is that the two-electron reduced beta-Lap is converted first to one-electron reduced beta-Lap, i.e., semiquinone beta-Lap (SQ).- causing production of reactive oxygen species (ROS), which then causes apoptotic cell death. The second mechanism is that severe depletion of NAD(P)H and NADH as a result of futile cycling between the quinone and hydroquinone forms of beta-Lap causes severe disturbance in cellular metabolism leading to apoptosis and necrosis. The relative importance of the aforementioned two mechanisms, i.e., generation of ROS or depletion of NAD(P)H/NADH, may vary depending on cell type and environment. Importantly, the NQO1 level in cancer cells has been found to be higher than that in normal cells indicating that beta-Lap may be preferentially toxic to cancer cells relative to non-cancer cells. The cellular level of NQO1 has been found to be significantly increased by divergent physical and chemical stresses including ionizing radiation. Recent reports clearly demonstrated that beta-Lap and ionizing radiation kill cancer cells in a synergistic manner. Indications are that irradiation of cancer cells causes long-lasting elevation of NQO1, thereby sensitizing the cells to beta-Lap. In addition, beta-Lap has been shown to inhibit the repair of sublethal radiation damage. Treating experimental tumors growing in the legs of mice with irradiation and intraperitoneal injection of beta-Lap suppressed the growth of the tumors in a manner more than additive. Collectively, beta-Lap is a potentially useful anti-cancer drug, particularly in combination with radiotherapy.

BACKGROUND: Although a number of indices of diastolic function based on transmitral flow have been proposed, no single factor seems to be adequate for seperating patients with normal from with abnormal diastolic functions. Pulsed Doppler echocardiography of pulmonary venous flow(PVF) is another non-invasive method to evaluate left ventricular diastolic performance. The purpose of this study is to evaluate the normal PVF pattern by TEE. METHOD: We performed pulsed-wave Doppler studies of the PVF and of the mitral flow by transesophageal-(TEE) and transthoracic echocardiography(TTE) in a healthy young adults. RESULTS: In TEE, all sublects showed four phases of the PVE pattern ; two antewgrade systolic phase(early and late : SE and SL), one antewgrade diastolic phase(D) and one retrograde diastolic phase(A). In TTE, there were three phases of the PVF pattern ; two antewgrade phase(systolic, diastolic) and one retrograde diastolic phase but we couldn't find out early systolic phase flow. Peak velocity of each phase of PVF was as follows:SE was 48.9+/-14.1cm/sec, SL was 56.3+/-16.1cm/sec, D was 52.6+/-14.9cm/sec. The timing of SL flow was correlated significantly with that of peak aortic flow(r=0.42, p=<0.01), while the timing of D flow and that of A flow were correlated significntly with timing of mitral E peak and A peak, respectively(r=0.84, p<0.01 ; r=0.80, p<0.01). CONCLUSIONS: In the young normal subject, PVF showed four phase of flow pattern and could be easily obtained by TEE. Furthermore it may be used for evaluation of left ventricular function.
