Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

14-3-3 proteins are cytoplasmic proteins of about 29 kDa and have a minimum of seven isoforms. This protein is important in signal transduction with the ability of binding with phosphoserine of many signalling proteins. We expressed 14-3-3 protein tagged with 6 histidine residues in E. coli and purified the protein by nickel affinity chromatography. Using this purified protein as an antigen, we made rabbit antisera and mouse monoclonal antibodies to 14-3-3 zeta isoform. We subcloned cDNA of 14-3-3 zeta isoform derived from HeLa cell lamda gt 11 library into an E. coli expression vector which is designed to express heterologous protein with N- terminal 6 hidtidine tag. BALB/c mice were immunized with purified 14-3-3 protein and the hybridoma clones which produce monoclonal antibodies angainst 14-3-3 protein were selected. These monoclonal antibodies reacted with the recombinant protein expressed in E. coli as well as the 29-kDa native protein in various cell lines. However, they did not immunoprecipitate 14-3-3 protein. The monoclonal antibodies produced in this study can be valuable tools for the identification of the 14-3-3 in signal transduction study.

Asian eyelids are characteristically puffy, with a fold, and have bulging of the orbital fat and septum. Moreover, with the aging process, the orbital septum and skin lose elasticity and orbital fat atrophy proceeds, thus resulting in dermatochalasis and a sunken eyelid. We introduce a modified technique of infrabrow excision with septo-myocutaneous flap repositioning. An upper incision was made along the lower margin of the eyebrow and the placement of the lower incision was decided according to the amount of skin excision needed. After skin removal, the orbicularis oculi muscle (OOM) was incised 2 mm above the lower margin and dissected to expose the orbital septum. Additional dissection was performed along the preseptal plane to the supraorbital rim periosteum. Then, the lower flap (septo-myocutaneous flap) was anchored to the supraorbital rim periosteum. The overlapping OOM and subcutaneous layers were sutured separately. This technique makes it possible to correct the cause of an aging eyelid appearance. Additionally, an overlapping OOM aids in correcting sunken eyelids, and by tensioning the orbital septum, a puffy eyelid is corrected. As an advantage over the conventional infrabrow excision, our method prevents recurrence and corrects orbital septum laxity. Therefore, it can achieve more natural outcomes and lower recurrence rates.

This study was performed to investigate the action of potassium channel openers on the mechanical activity of detrusor muscle isolated from rats. Detrusor muscle strips, 15 mm in length, were myographied isometrically in an isolated organ bath. P 1060, RP 49356 and BRL 38277, potassium channel activators, reduced the basal tone and diminished the phasic activity of detrusor concentration-dependently. P 1060, RP 49356 and BRL 38227 suppressed the maximal responses to bethanechol and shifted the concentration-response curves of bethanechol-induced contraction to the right. RP 49356 and BRL 38227 reduced the contraction by low (20 mM) concentration of potassium. P 1060, however, diminished the high (80 mM) and low (20 mM) concentration of potassium-induced contraction. Glibenclamide, an inhibitor of ATP-dependent potassium channel, antagonized the suppressive action of P 1060, RP 49356 and BRL 38227 on the basal tone. Apamin or procaine did not antagonize it significantly. Based on these results, it is suggested that the relaxation of detrusor muscle strip caused by P 1060, RP 49356 and BRL 38227 may predominantly involve opening of the same potassium channel, i.e., the ATP-dependent potassium channel.

We examined the role of cell adhesion molecules (CAM) by which tumor cells bind to the endothelial cells using human umbilical vein endothelial cells (HUVEC) and cultured melanoma cells. Endothelial cells from human umbilical veins were isolated and examined for CAM expression and its modulation by tumor necrosis factor-alpha (TNF-alpha), interleukin-1 (IL-1), interleukin-6 (IL-6) or interferon-gamma (IFN-gamma). The expression of intercellular adhesion molecule 1 (ICAM-1) on HUVEC was increased by TNF-alpha, IL-1 and IFN-gamma when measured by ELISA or flow cytometric (FACS) analysis. IL-6 did not increase ICAM-1 expression on HUVEC. Two melanoma cell lines, Malme-3M and SK-Mel-28, showed increased expression of ICAM-1 after treatment with TNF-alpha, IL-1 and IFN-gamma in FACS analysis. IFN-gamma induced increased expression of HLA-DR only in SK-Mel-28 melanoma cells, not in Malme-3M melanoma cells. Neither HUVEC nor melanoma cells expressed lymphocyte function-associated antigen 1 (LFA-1) in either the basal (i.e., cytokine untreated) condition or the cytokine treated condition. Melanoma cells showed minimal increment in adhesion to TNF-alpha or IL-1 treated HUVEC than to cytokine untreated HUVEC. HUVEC and melanoma cells did not express LFA-1 and increased ICAM-1 expression by TNF-alpha, IL-1 and IFN-gamma treatment in FACS analysis did not coincide with minimal increase of melanoma cells adhesion to cytokine treated HUVEC. These results suggest that adhesion between melanoma cells and HUVEC is probably mediated by molecular interaction other than ICAM-1/LFA-1.

Midazolam and propofol by continuous intravenous infusion produce excellent and easily controllable sedation as an adjunct to spinal anesthesia. The purpose of the present study is to compare the cardiovascular and respiratory effect, degree of sedation and recovery of midazolam and propofol, and then determines the mean infusion rate of both groups. Forty patients of ASA class 1 or 2 scheduled to lower extremities surgery under spinal anesthesia were classified randomly into 2 groups. Group 1 were infused with midazolam 0.1-0.2mg/kg/h and group 2 propofol 2-3mg/kg/h. The results were as follows: 1) The mean induction dose of midazolam was 0.29+/-0.03mg/kg/h and propofol was 5.56+/-0.78mg/kg/h and the mean infusion rate of midazolam was 0.09+/-0.02mg/kg/h and propofol was 2.13+/-0.41mg/kg/h, which resulted in easily controllable sedation during operation. 2) The quality of sedation was assessed as good in 19 patients but 1 patient showed excitatory movements after midazolam infusion. Good sedation was provided in 16 patients but 2 patients showed excitatory movements and 2 patients complained pain on injection after propofol infusion. 3) The mean arterial pressure was more significantly decreased in propofol than midazolam group. 4) The heart rate was more decreased than control in both groups. 5) Airway maintenance was excellent and side effects were rare. 6) Recovery, judged by ability to open the eyes and recall date of birth, was significantly more rapid after propofol than after midazolam infusion.
