PURPOSE: To evaluate the effectiveness and complication rate of our modified continuous buried suture technique for the correction of the upper lid epiblepharon. METHODS: This retrospective study included 132 eyes of 66 patients, who were diagnosed with upper lid epiblepharon from March 2000 through April 2002 After the followup of over 6 months, we evaluated the improvement and recurrent rate of epiblepharon after the procedure. RESULTS: In 131 of 132 eyes with the mean followup period of 12.9 months, the epiblepharon was corrected successfully with cosmetically satisfactory Results. In 1 eye, we experienced the disappearance of a double fold without the recurrence of the epiblepharon. CONCLUSIONS: This modified continuous buried suture Method appears to be an effective treatment of lash inversion in upper lid epiblepharon with good aesthetic Results.

A preparation of water soluble components(EA) was made from carpophores of Elfvingia applanata(Pers.) Karst and its in vitro antibacterial activity on a number of bacterial species was examined by macrobroth dilution assay. Among 16 species of bacteria tested, the most potent antibacterial activity was observed against Staphylococcus epiderrnidis and Proteus vulgaris, of which MICs were 1.25 mg/ml. To investigate the antibacterial effects in combinations of EA with quinolone antibiotics, such as ciprofloxacin, enoxacin, lomefloxacin, norfloxacin, and ofloxacin, the fractional inhibitory concentrations(FICs) and the fractional inhibitory concentration indices(FICIs) for four bacterial strains were determined by macrobroth dilution checkerboard assay. Combinations of EA and quinolones exhibited either additive or indifferent effects of antibacterial activity in most instances. However, both synergistic and antagonistic effects were not observed in any cases.

PURPOSE: Complete resection of the tumor nodule(mural nodule or solid portion of the tumor) is the essential goal of surgical treatment for heman-gioblastoma. The purpose of this study was to classify the morphologic types of intracranial hemangioblastoma on MRI and to compare the location and contour of tumor nodule on MRI with those on angiography. MATERIALS AND METHODS: The MRI findings of 34 lesions(38 lesions if 4 spinal cord lesions were included) in 26 patients(17 males and 9 females, range of age, 18-67 years, mean, 39 years) with surgically and histopathologically proved intracranial hemangioblastomas were reviewed. Seventeen patients underwent CT scanning in a short interval. Contrast-enahnced T1 -weighted imaging pa- tterns of hemangioblastoma were classified according to Ho's morphologic types. The location and contour of tumor nodule were compared between MRI and angiography in 15 patients(24 lesions). RESULTS: By location, cerebellar hemisphere was predominated(55%), followed by cerebellar vermis(26%), supratentorial region(5%), and medulla oblongata (3%). Spinal cord lesions(11%) were seen in 3 patients of 5 von HippeI-Lindau diseases. The frequency of morphologic types was as follows; Type 1 (purely cystic), 3%, Type 2(mural nodule), 50%, Type 3(cyst with wall enhancement), 3%, Type 4 (cystic nodule), 15%, Type 5(solid with internal cyst), 9%, and Type 6(solid), 20%. All tumor nodules(33 lesions) enhanced intensely with intravenous contrast material on MRI, of which 24 lesions(in 15 patients) revealed hypervascular masses fed by pial arteries on angiography. They were superficial and abutted pia mater partially or in large portion on both MR I and angiography. CONCLUSION: Over 70% of intracranial hemangioblastomas had a surrounding cyst, and superficial, pial-based location and number of the tumor nodules on MRI was correlated well with those on angiography. MRI is the examination of choice for preoperative evaluation of intracranial hemangioblastoma.

In the management of carotid cavernous fistula, detachable balloon has become the treatment of choice.However, technical difficulties are not uncommon, and transarterial balloon embolization fail in 5% to 10% ofcases. Failure occurs because in some patients, the fistula orifice may be too small to allow entry. Using atracker catheter system with Guglielmi detachable coils, we achieved successful transarterial occlusion of acarotid cavernous fistula with a small fistula.

27-Hydroxycholesterol induces differentiation of monocytic cells into mature dendritic cells, mDCs. In the current study we sought to determine roles of the PI3K and the ERK pathways in the 27OHChol-induced differentiation. Up-regulation of mDC-specific markers like CD80, CD83 and CD88 induced by stimulation with 27OHChol was significantly reduced in the presence of LY294002, an inhibitor of PI3K, and U0126, an inhibitor of ERK. Surface expression of MHC class I and II molecules elevated by 27OHChol was decreased to basal levels in the presence of the inhibitors. Treatment with LY294002 or U0126 resulted in recovery of endocytic activity which was reduced by 27OHChol. CD197 expression and cell adherence enhanced by 27OHChol were attenuated in the presence of the inhibitors. Transcription and surface expression of CD molecules involved in atherosclerosis such as CD105, CD137 and CD166 were also significantly decreased by treatment with LY294002 and U0126. These results mean that the PI3K and the ERK signaling pathways are necessary for differentiation of monocytic cells into mDCs and involved in over-expression of atherosclerosis-associated molecules in response to 27OHChol.

We attempted to investigate molecular mechanisms underlying phenotypic change of vascular smooth muscle cells (VSMCs) by determining signaling molecules involved in chemokine production. Treatment of human aortic smooth muscle cells (HAoSMCs) with thrombin resulted not only in elevated transcription of the (C-C motif) ligand 11 (CCL11) gene but also in enhanced secretion of CCL11 protein. Co-treatment of HAoSMCs with GF109230X, an inhibitor of protein kinase C, or GW5074, an inhibitor of Raf-1 kinase, caused inhibition of ERK1/2 phosphorylation and significantly attenuated expression of CCL11 at transcriptional and protein levels induced by thrombin. Both Akt phosphorylation and CCL11 expression induced by thrombin were attenuated in the presence of pertussis toxin (PTX), an inhibitor of Gi protein-coupled receptor, or LY294002, a PI3K inhibitor. In addition, thrombin-induced production of CCL11 was significantly attenuated by pharmacological inhibition of Akt or MEK which phosphorylates ERK1/2. These results indicate that thrombin is likely to promote expression of CCL11 via PKC/Raf-1/ERK1/2 and PTX-sensitive protease-activated receptors/PI3K/Akt pathways in HAoSMCs. We propose that multiple signaling pathways are involved in change of VSMCs to a secretory phenotype.
