The effects of cilostazol (OPC-13013, 6-[4-(1-cyclohexyl-1H-tetrazol-5-yl)butoxy]-3,4-dihydro-2(1H)-quin olinone) on cyclic nucleotide metabolism and Ca2+-induced contraction of intact and skinned rabbit arterial smooth muscles were investigated. The concentrations of cilostazol producing 50% inhibition of cyclic adenosine monophosphate phosphodiesterase(More)
PURPOSE To find out an effective prognostic factor for early stage non-small cell lung cancer (NSCLC), we examined the relationship of the degree of tenascin-C (TN-C) degradation in relapsed NSCLC tumors with the prognosis of the patients. The molecular mechanism of TN-C degradation was also evaluated. EXPERIMENTAL DESIGN In 63 stage-1 NSCLC patients,(More)
BACKGROUND Transluminal stent-graft placement (TSGP) for aortic dissection is a relatively new procedure. We performed TSGPs to seal the primary entry site to treat and prevent complications of aortic dissection. The early to mid-term outcomes were analyzed. METHODS AND RESULTS Thirty-seven patients with a primary intimal tear in descending aorta(More)
The aim of this study was to investigate how insulin secretion is controlled by phosphorylation of the myosin light chain (MLC). Ca2+-evoked insulin release from pancreatic islets permeabilized with streptolysin O was inhibited by different monoclonal antibodies against myosin light-chain kinase (MLCK) to an extent parallel to their inhibition of purified(More)
Monoclonal antibodies raised against rabbit brain protein kinase C were classified into at least three types, MC-1a, MC-2a, and MC-3a, which selectively interact with hydroxyapatite column chromatographically resolved isozymes type I, II, and III of protein kinase C, respectively, determined on the basis of immunoblotting experiments. Immunoprecipitating(More)
OBJECTIVE Neointimal hyperplasia at the arterial anastomotic site is a critical problem during cardiovascular surgery. It has been suggested that tenascin-C (TN-C), an extracellular matrix (ECM) glycoprotein, might play an important role in neointimal hyperplasia. In this study, the direct contribution of tenascin-C to neointimal hyperplasia after aortotomy(More)
OBJECTIVE Accumulation of smooth muscle cells and extracellular matrix in the intima of artery bypass grafts induces neointimal hyperplasia, resulting in graft failure. We investigated the inhibitory effect of locally applied cilostazol, an inhibitor of cyclic adenosine monophosphate phosphodiesterase III, on neointimal hyperplasia and the role of(More)
BACKGROUND Transluminal stent-graft placements (TSGPs) are a new, less invasive procedure now recognized as the choice for aortic disease repair. Treatment of aortic dissections with TSGPs has resulted in good early results, but the long-term results and changes in the false lumen have not been elucidated in detail. METHODS AND RESULTS TSGPs were(More)
Background: Bronchorrhea is one of late complaints in patients with bronchioloalveolar carcinoma (BAC) and hampers their quality of life. Although an effective treatment for bronchorrhea in these patients has not been established, recently we have treated effectively one case of persistent bronchorrhea associated with clinical recurrent BAC with gefitinib(More)
