Computed Tomograms of 45 patients with or without lung mass were reviewed to determine the characteristics of the major and minor fissures. Also pulmonary vascular distibutions were analyzed to localize each pulmonary lobe. The results were as follows; 1. Each major fissure area was imaged frequently as lucent band, less frequently dense band. 2. The minor fissure areas were imaged as oval or triangular lucent zones. The oval or triangularlucent zones were as same frequency. 3. Avascular planes without above mentioned lucent zones were also correspond to minor fissure areas. 4. Slices of avascular zones were observated between pulmonary arteries to posterior segment or apicoposterior segment of upper lobe and to superior segement of lower lobe on both lungs.

PURPOSE: Antenatal steroid(ANS) therapy in premature infants is an effective therapeutic strategy in reducing the incidence of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and patent ductus arteriosus. For premature infants to gain improved survival, adequate weight loss during early postnatal days and maintenance of electrolyte balance is important, however, it is uncertain that ANS affect them. We hypothesized that ANS augment fluid and electrolyte balance and dinical outcome of very low birth weight(VLBW) who had received restricted fluid regimen. METHODS: Mechanically ventilated VLBW infants who survived over 30 days were selected. We reviewed medical records to compare weight loss, urine output, electrolyte concentration, blood pressure during five days of life and clinical outcome between premature infants who received ANS(n=15) and who were not(n=58). RESULTS: Gestational age, birth weight were similar between two groups. Volume of administered fluid, urine output, and initial weight loss during first five days of life were similar, however, weight loss on postnatal day five were lower in study group than control group(p=.039). Blood pressure, serum sodium concentration, serum potassium concentration, and urine specific gravity were similar between two groups. Incidence of respiratory distress syndrome was lower in study group(20%) than control group(48%)(p=.041), however, incidence of sepsis were greater in study group(33%) than control group(7%)(p=.029). CONDUSION: ANS did not affect fluid and electrolyte balance of very low birth weight(VLBW) infants who had received restricted fluid regimen. ANS decreased the incidence of respiratory distress syndrome in this population, however, increased the incidence of sepsis.

OBJECTIVE: The aim of this study was to assess the relationship between disease progression and expression of c-erbB-2 and S-100 protein positive dendritic cells in Cervical cancer. STUDY DESIGN: Tissues were analyzed from 100 patients. Each of them had invasive carcinoma(44), microinvasive(12), CIS(33), CIN(II) before treatment, c-erbB-2 oncoprotein expression and S-100 protein positive dendritic cell were confirmed by immunohistochemical staining. (Avidin-biotin complex method) RESULTS: C-erbB-2 immunostaining was significantly associated with disease progression (p<0.05). In case of CIN I, there was not noted stained specimen but in case of invasive carcinoma, 24 cases of stained specimen were noted. S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.(p>0.05) CONCLUSIONS: According to our results, c-erbB-2 is possible factor in Carcinogenesis of cervical carcinoma with progression of it. and S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.

A case of Wegener's granulomatosis is described, with special attention focused on the typical histologic findings and involvement of both middle ear and lung. The patient is a 37-year-old man presented with four-month history of cough and sputum. He had a past history of surgery of both ears because of otitis media followed by left facial palsy. Chest radiographs showed variable sized ill defined nodules in both lower lobes with internal airspace consolidation. Histologic preparations of the open lung biopsy specimens demonstrated a diffusely scattered palisading micro and macrogranulomas with central focus of neutrophils and necrotic collagen surrounded by histiocytes, histiocytic giant cells. Fibrinoid necrosis involved blood vessels and lung parenchyma. Chronic inflammation, diffuse granulation tissue formation and irregular fibrosis are also found in the lung parenchyma. The histologic findings of middle ear which was previously biopsied showed scattered palisading ill defined microgranulomas mixed with fibrotic tissue.

It is supposed in Korea that institutional care for the elderly would increase while their home care would decrease. Assessment of the functional status is of much importance for effective caregiving for the institutionalized people. The functional status was evaluated in 89 elderly residents of an institution in Taegu, using the Korean version of the mini-mental state examination, the Blessed Dementia Rating Scale, the Barthel Activities of Daily Living, and the Motoricity Index. Vision and hearing were also examined. Based on scores of the Korean version of mini-mental state examination, 45% were found to have definite cognitive impairment and further 25% to have questionable cognitive impairment. About 35% of the subjects possibly had mild or more severe dementia on the Blessed Dementia Rating Scale. Fifty-seven percent had impairment in activities of daily living, and 66% had impairment in motor power. Sixteen percent and 20% had poor vision and hearing difficulty, respectively, to the degree of impairment in daily activities. These findings indicate that more than half of elderly people in institutional care may need either partial or total help from others.

PURPOSE: In the treatrnent of respiratory distress syndrome, Infants are often exposed to hyperoxia. It can generate oxygen free radical, damage to lung and bronchi, and inactivate pulmonary surfactant(PS). Antioxidant therapy in animal and human models has been tried to overcome this detrimental effects. We hypothesized that the addition of oxygen free radical such as hydrogen peroxide(H) could compromise surface active properties(SAP) of PS and that further addition of antioxidant such as catalaseR(CAT, Sigma chemical, St. Louis) could recover SAP. METHODS: We prepared combinations of mixtures with SurfactenR(S-TA, Tokyo Tanabe, Japan), H202 and CAT. 1)0.625mgPL(phospholipids)/ml or 1.25mgPL/ml S - TA and H202 were mixed to the final concentrations of 0.1 and 1mM H respectively, and incubated at 37C for one hour. 2) 0.625mgPL/rnl S - TA, H202 and CAT 10U were mixed to the final concentrations of lmM H202, and incubated at 37 degree C for one hour. We used Pulsating Bubble Surfactometer (Electronetics, NY) measure in vitro minimum and maximum surface tensions(ST) and area-surface tension relationship. RESULTS: 1) For 0.625mgPL/ml S-TA and 1mM H mixture minimum. ST after 5 min of pulsation increased significantly(P=0.007) and the area-surface tension curve was deformed. But they were comparable to control levels for 1.25mgPL/ml S-TA. 2) When CAT was added to 0.625mgPL/ml S-TA and 1mM H mixture, the resultant minimum ST after 5 min of pulsation dropped to the control levels with recovery of hysteresis curve(P=0.0001). CONCLUSION: PS could be inactivated by addition of high concentrations of H but SAP can be recovered either by increasing PS concentration or by further addition of antioxidant CAT. Therefore, we suggest that in case of suspected surfactant inactivation an increase in surfactant concentration or administration of antioxidant must be considered.

This study includes 19 cases of complicated low extremity injury to whom underwent microvascular free-tissue transfer in cases of open comminuted fracture, osteomyelitis, and vascular compromise or extensive soft tissue defect from Nov. 1994 to July 1997. The average time after injury to coverage was 25 days. The nineteen patients underwent a total of nineteen free tissue transfers primarily, and eighteen (94.7 per cent) of the transfers survived. Major complications were encountered recurrent failure of the free tissue transfer in one patient and partial necrosis in the other flap, which were successfully treated by flow-through radial forearm free flap and distally based superficial sural artery flap respectively. Two patients were sustained below knee amputation, one above knee amputation, despite of survival of flaps. This reveals limb salvage in 84 percent. The microvascular reconstruction is a versatile and reliable methods in complicated cases after severe trauma. Free tissue transplantation should be considered as a primary treatment in such complicated cases.
