Background: Univent(R) tube was designed to overcome the disadvantages of double lumen endotracheal tube for one lung anesthesia. But overinflation of the blocker cuff of an endobronchial tube can cause pressure damage to the bronchus. The purpose of this study was to evaluate whether the blocker cuff pressure and the duration of ballooning using the Univent(R) tube is correlated with the degree of bronchial mucosal damage (BMD). Methods: A total of 13 men and 7 women intubated with the Univent(R) tube were enrolled for the study. The BMD were evaluated by direct visualization using fiberoptic bronchoscopy prior to intubation and following extubation and the degree of the BMD were scored from 0 to 4 as follows; 0: normal, 1: erythema, 2: swelling, 3: hemorrhage, 4: mucosal wall tearing. Results: No change in bronchial mucosa (score 0) were observed in 11 patients (55%), erythema (score 1) in 5 patients (25%), swelling (score 2) in 3 patients (15%), hemorrhage (score 3) in 1 patient (5%) and mucosal wall tearing (score 4) is none in 20 patients. The bronchial blocker cuff pressure required to "just sealing" the bronchus was 178.1+/-37.4 mmHg with corresponding cuff volume of 6.7+/-1.0 cc. The duration of ballooning was 115.5+/-26.4 min. The correlation coefficient between the blocker cuff pressure and duration of ballooning to the degree of bronchial mucosal damage were 0.125 and 0.137, respectively, which was not statistically significant. Conclusions: The bronchial blocker of Univent(R) tube doesn't cause any severe BMD and the degree of BMD are correlated with neither the bronchial blocker cuff pressure nor duration of ballooning of Univent(R) tube.

BACKGROUND: Neurofibroma, the hallmark of neurofibromatosis, is a cutaneous or subcutaneous lesion, with a variable clinical presentation. Histologically, neurofibroma consists of proliferation of nerve derived cellular elements, together with an abundant, collagenous extracellular matrix. Specifically, neurofibroma has been shown to contain 30-50% collagen in its matrix. Objective 5. METHODS: We examined the expression of extracellular matrix genes (collagen, fibronectin, laminin), TGF-b mRNA and Ha-ras oncogene mRNA by using Northern and slot-blot hybridization and immunoperoxidase stains. Result: In Northern blot analysis, Ha-ras and TGF-b genes revealed respectively, 8.8kb and 2. 5kb sized mRNA transcripts in neurofibroma. These parameters were normal in the control. The expression of these genes were 1.9, 2.0 fold increased in neurofibroma. In slot-blot analysis, expression of type I collagen showed fibronectin genes to be 2,401+210, 540+43, respectively, in neurofibroma. So there were 3.7 fold, 2.1 fold, differences respectively, compared to the normal control. However, there were no significant changes of type IV collagen and laminin Bl mRNA levels between neurofibroma and normal skin tissues. Irnmunoperoxidase staining by rnonoclonal anti type IV collagen antibody in neurofibroma showed type IV collagen to be diffusely and weakly stained in tissue. On staining by monoclonal anti-laminin antibody, laminin was stained in a matrix and around vessels. CONCLUSION: The increased expression of extracellular matrix genes may suggest that there is a subpopulation of fibroic cells in neurofibroma which are stimulated by TGF-b. Ha-ras genes which might have accumulated with the differentiation of neural tissue may be related to the pathogenesis of neurofibroma tissue formation. Further studies are needed to determine whether the other factors are related to the pathogenesis of neurofibroma.

An 41-year-old woman with chronic active hepatitis developed multible asymptomatic erythematous papules, plaques and purpuras on the both lower leg, feet, forearms and hands. Some lesions progressed to ulcers with central black colored necrotic eschars. Biopsies and cultures demorrstrated a fungus, aspergillus fumigatus a the etilogic agent. No evicience of involvement of other organs by aspergillus fumigatus was found. Intravenous amphotericin B therapy was discontinued because of he immediate adverse effects. The patient received treatment with oral itaconazole(200mg/day) and intravenous fluconazole(400mg/day), but skin lesions have been recurring repeatedly.

A 26-year-old Korean man had an erythematous scaly plaque on his right thigh for fifteen years. He was diagnosed with chronic eczema and treated with topical steroid, but no clinical improvement was obtained for 15 years. Laboratory studies including complete blood cell count, urinalysis, liver and renal function test, and peripheral blood smear were normal. A biopsy specimen showed hyperkeratosis, acanthosis, and mononuclear cellular infiltration in the epidermis. These cells had a perinuclear halo and showed a Pautrier's microabscess like configuration. In the dermis, there was a band like infiltration of inflammatory cells. Infiltrates of the epidermis were negative for leukocyte common antigen(CD45) and positive for Pan T cell(CD45RO). He was treated with topical PUVA twice a week for twelve weeks. Clinical and pathological improvements were obtained. We propose PUVA may be a useful therapeutic modality to treat Woringer Kolopp disease.

The pathophysiology of pediatric encopresis has been incomprehensible. The current study was designed to assess its clinical and physiologic findings. Moreover, outcome of treatment was evaluated. METHODS: The clinical and functional findings of 18 patients (13 boys, 5 girls) were analyzed, retrospectively. Physiologic studies for cooperative child included anal manometry (n=12), cinedefecography (n=3), and PNTML (pudendal nerve terminal motor latency, n=1). For exclusion of the organic cause, barium contrast study was carried out in all case. Patients were categorized by leading symptom as constipation or incontinence. Physiologic findings and outcome of treatment were analyzed based on the categorized groups. Biofeedback therapy by using newly-developed anal sphincter control system (KONTINENCE CLINICAL(TM)) in my institute, was underwent a mean 4.1 (range, 2~12) sessions. The outcome was analyzed in the period of 5.4 (range, 1~33) months follow-up. RESULTS: Patients were categorized as having constipation (group I, n=12) or incontinence (group II, n=6) group. In the manometric parameters, there were no statistical differences between the values of the mean resting pressure (RP), the maximum RP, and the maximum voluntary contraction between group I and II. In the cinedefecography, 3 of group I patients revealed as having the pelvic floor dyssynergia. The findings of PNTML were not specific in group II (n=1). Regarding to the therapeutic outcome, 8 of 10 patients were cured or improved. CONCLUSIONS: There were no differences in the resting and squeeze profiles of manometric parameters between two groups. However, pelvic floor dyssynergia was identified in the cinedefecography of constipated group. Conventional and biofeedback treatment for encopretic children provides acceptable outcome.

BACKGROUND: Mycosis fungoides(MF) is a form of cutaneous T cell lymphoma with clonal differentiation of helpr' T cell. It has a patch, plaque, and tumor stage. But pathogenetic factors controlling the development and progression of MF are still unclear. Apoptosis plays a major role in developmental biology and homeostasis. The bcl-2 oncogene prolongs ce11 life by inhibiting apoptosis. The mutant pS3 gene induces apoptosis indirectly. Ki-67 antigen is the cell proliferation marker. Recently, it has been shown that the relationships among them are important in the tumorigenesis of the various tumors. OBJECTIVE: The aim of this study was to examine the expression of these genes and apoptotic rate and clarify the relationship among them in the development and progression of MF. METHODS: The eighteen specimens from 8 patients with MF and 10 specimens from benign lymphocytic infiltrating diseases including 5 lichen planus, 3 lupus erythematosus, and 2 contact dermatitis were included. We performed immunoperoxidase staining(LSAB technique) using monoclonal antibodies including bc1-2, p~53, and Ki-67(MIB1). We used ApoptaqTM(Oncor) in situ labelling kit for detecting apoptotic cell.

PURPOSE: It is important to have the epidemiologic data of rotavirus serotypes for the application of polyvalent rotavirus vaccines. Epidemiological studies of rotavirus serotypes in Korea have been reported only in limited areas with small number of cases. Authors tried to investigate the distribution of rotavirus G serotypes in ChungJu area with RT-PCR. METHOD: Stool specimens were collected from 202 children with acute diarrheal symptoms, who admitted to or visited Kon-Kuk University Hospital in ChungJu from June 1998 to May 1999. Samples were screened for rotavirus with EIA method (TestPack Rotavirus, Abbott Laboratories) and rotavirus G Serotypes were determined by RT-PCR. RESULTS: Rotavirus was positive in 46.6%. The incidence of G serotypes was as follows; G1 10%, G2 10%, G3 28%, G4 26%, and G9 20%. There were three cases of multiple serotypes; G1 with G9, G2 with G9, and G4 with G9. Serotype of G8 was not found. CONCLUSION: The proportion of G serotypes in ChungJu is much different from previous reports. Serotype of G9 was found which had not been reported in Korean children till now. Long term plans for the investigation of rotavirus serotypes must be needed in wide area.

Pulmonary thromboembolism (PTE) is a significant cause of death in the hospitalized patient in the western and developed countries. The development of PTE and venous thrombi is associated with many and various factors, including that physicians fail to provide adequate prophylaxis to the high risk patients. The authors studied 74 legal autopsy cases performed from 1996 to 2000 at the Headquarters of National Institute of Scientific Investigation, Seoul, Korea. We learned that ceasarian section was the most common precedong trauma in PTE death in legal cases. Excluding Ceasarian section cases, major mechanical injuries, male gender and aging were common factors associated with PTE. Obesity was a common factor in all kinds of trauma. Deep vein thrombi were documented in majority cases and ambulation was a critical triggering cause for the thrombi making PTE. Clinical diagnosis was not so satisfactory.
