In this study, it was conducted to improve the physical properties of VAE polymer matrix used as a coating material. A nanocomposite was manufactured using graphene as a reinforcing agent based on a VAE matrix. As a result, improvements in tensile strength, adhesion strength, and porosity were confirmed.

Chronic mesenteric ischemia is characterized by postprandial pain and marked weight loss. It is provoked by inadequate intestinal blood flow and the increased metabolic demands associated with digestion. Diagnosis must be based on clinical symptoms, arteriographic demonstration of an occlusive process of the splanchnic vessels, exclusion of other gastrointestinal disorders, and the response to revascularization. Specially, angiography is indicated to confirm the diagnosis, to assess disease severity, and to plan revascularization. It can be treated by either surgical reconstruction of an artery or percutaneous transluminal balloon angioplasty with or without stenting. We had experienced a 63-year-old man who presented with postprandial abdominal pain and weight loss unexplained by conventional diagnostic studies. The aortography revealed about 80% of stenotic lesion in the superior mesenteric artery. After percutaneous transluminal angioplasty, postprandial abdominal pain was completely relieved. We report a case of chronic mesenteric ischemia with a review of relevant literature. (Korean J Gastroenterol 2003;41:499-503)

Tracheal intubation is the most common cause of Tracheal stenosis. The treatment of trachea stenosis vary according to site or size of tracheal stenosis. Thirty six age old man was transferred our hospital for evaluation of dyspnea. Subglottic stenosis was shown on bronchoscopy & chest computerized tomography(CT) scan of neck. Balloon dilatation was performed and then patient breathed at ease. Tracheal resection and end-to-end anastomosis was applied to repetitive tracheal stenosis. Balloon dilatation before surgical management makes better respiratory difficulty. We report succesful application of surgical management after balloon dilatation in repetitive tracheal stenosis patient. We will suggest that the balloon dilatation improve symptoms before tracheal resection and end-to-end anastomosis or stent, if sugery or stent insertion are not applicable due to poor status of patient.
