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.

A 25-year-old man with familial benign chronic pemphigus presented with a one-year history of a localized pruritic recurrent eruption on his perianal area, Physical examination showed moist, macerated, fissured and scaly patches on erythematous base, A biopsy specimen showed extensive intraepidermal separation containing acantholytic cells. Electron microscopic observation showed widened intercellular space, detachment of the tonofilaments from the desmosomes, and subsequent concentration of the tono filaments around the nucleus. Microvilli were elorigated, thinned and branehed. 1)esmosomes were reduced in number. This case is unique in its clinical location, showing no family tendency.

We presents a case of metastatic squarnous cell carcinoma(SCC) with multiple Bowen's disease. A 34--year-old rnale patient visited our OPD due to a bady-fist sized hard palpable mass on the left inguinal area and multiple, scattered, brownish, variable sized, verrucous papules on the whole body. About 6 months later, he cornplained dyspnea and collapsed left lower lobe was seen in the chest PA. Histopathologically, metastatic SCC and Bowen's disease were seen in the sections frorn left inguinal mass, lung lesion and verruous papule respectively. We suspected that left inguinal mass and lung lesion is metastasized from right palm lesion.

We report a case of tinea incognito occurring in a 47-year-old woman who deveoped erythematous papules and scaly patches on whole body after taking corticosteroid therapy intermittently over a period of 3 months. Direct smear and culture for fungus of the lesions demonstrated hyphae and C. albicans and T. mentagrophytes, which confirms the diagnosis. The lesions disappeared three months after systemic and topical antifungal therapy.

We report herein a case of pityriasis rubra pilaris in a 39-year-old male, who had erythematous scaly patches on the face, trunk and extremities for one year. The skin lesion showed well defined plaques on the elbow and knee joint areas, and exfoliative hyperkeratotic sheets with fissures on the palms and soles. He had no family and past history of such skin lesion. He was treated with etretinate lmg/kg/day for 1 week initially, and then tapered off 0.5mg/kg/day for 5 weeks with marked improvement. There was no exacerbation and recurrence of the skin lesion for about 1 year.

Recently, many investigators demonstrate that immunologic mechanisms seem to play an important role in the pathogenesis of Behcet's disease. The present study was undertaken to see the possible roles of NK cell activity in the pathogenesis of Behcet's disease and relationship among NK cell and T-cell and T-subsets. Authors evaluated NK cell activities in 14 patients and T cell, t-subsets in 7 patients. The results were as follows ; 1. The mean value of NK cell activities showed no statistically significant difference between patients group(57.1+/-15.8) and normal healthy control group(56.1+/-16.2). 2. The mean value of T cell(T), T-subsets(T,T)in 7 patients group 74.4+/-9.8, 41. 6+/-8.0, 24.4+/-10.1 showed no statistically significance compared with the mean value of normal healthy control group 67.5+/-4.3, 39.7+/-5.6,26.3+/-6.0 respectively. 3. The mean value of NK cell activities showed no statistically significant difference between 7 complete type patients' group(49.6+13.1) and 7 incomplete type patients' group(64.4+15.6)

BACKGROUND: Recently, it has been established that plateletpheresis needs more efficiency and shorter processing time. Fenwall laboratories developed a new collection chamber for CS-3000 Plus, PLT-30TM collection chamber, which can reduce the processing time with efficient collection. We evaluated the PLT-30TM collection chamber by comparing it with A-35 collection chamber that has been used as a standard collection chamber of CS-3000 Plus us. METHODS: Thirty platelet collection procedures were performed using the CS 3000 Plus with A-35 collection chamber and PLT-30TM collection chamber. The changes of the hematologic parameters between pre- and post-donation in donors and the total platelets yields and the contaminated WBCs in the plateletpheresis products were evaluated. In processing, the yield predictor calibration was adjusted to 1.00 and 1.13 in A-35 and PLT-30TM respectively. Yield predictors of pheresis were the same as 3.5x1011 in both and end point volumes were calculated from the CS-3000 Plus. Processing volume and processing times were compared between A-35 and PLT-30TM groups. RESULTS: With PLT-30TM collection chamber, 3.38+/-0.72x1011/L platelets were harvested, whereas 3.20+/- 0.73x1011/L were collected with A-35 collection chamber, which was not significantly different. But processing time with the PLT-30TM collection chamber was more reduced than that with the A-35 collection chamber by about 20 minutes (PLT-30TM : 88.6+/-8.4 min, A-35 : 106.7+/-11.7min). Collection efficiency of PLT-30TM chamber was 50.7+/-12.5% and that of A-35 chamber was 44.4 + 8.8%. The leukocyte contamination of the platelet concentrates were not statistically different(PLT-30TM: 0.0-3.6x106, A-35 : 0.1-4.1x106). CONCLUSIONS: PLT-30TM collection chamber has the advantages of shortening the donation time and decreasing the processing volume with better collection efficiency and flexibility of platelet concentrate volume.
