Caveolin-1 (Cav-1) is the structural protein that is necessary for the formation of caveolae membrane domains. It is known as an inhibitor of various signaling pathways and associated with several diseases such as cancer, atherosclerosis, restrictive lung disease and obesity. However, studies for Cav-1 in nose has been hardly performed. The objectives of our study were to detect Cav-1 expression in human nasal epithelium and to investigate the change of Cav-1 expression in the inflammation of nasal epithelium. Subjects and Method:We obtained nasal polyp specimens from three patients undergoing endoscopic sinus surgery. Cells from specimens were cultured using the air-liquid interface technique and IL-1β was treated. The expression of Cav-1 mRNA and protein was determined by reverse transcription-polymerase chain reaction (RT-PCR) and western blot analysis, respectively. Results:Both RT-PCR and Western blot analysis demonstrated the presence of Cav-1 mRNA and protein in human nasal epithe-lium. Furthermore, the expression of both Cav-1 mRNA and protein was decreased by IL-1β stimulation. Conclusion:Cav-1 was expressed in human nasal epithelial cells. It is assumed that Cav-1 may play a role in nasal inflammatory disease. However, further studies to confirm the interaction between Cav-1 and signaling molecules in the nasal inflammatory process should be followed.

Background and Objectives:The aim of this study was to determine the otolithic effects of galvanic vestibular stimulation on the perception of subjective visual vertical in normal subjects. Subjects and Method:Fifteen normal subjects were selected on the basis of medical history and neurological examination. We measured subjective tilt of a central vertical line during galvanic vestibular stimulation (0, 1.0, 2.5, 4.0 mA). Binaural and monaural electric current was applied to each subjects mastoid and forehead for vestibular stimulation. Results:Anodal stimulation of the right mastoid led to clock-wise subjective visual vertical. Anodal stimualtion of the left mastoid led to counter clock-wise subjective visual vertical. There was a correlation between the amount of the measured parameter and the strength of the applied current. More consistent parameters were obtained from the binaural stimulation than the monaural stimualtion. Conclusion:Galvanic vestibular stimulation had effects on the vestibular functions, making changes in the subjective visual vertical. Since the galvanic stimulation had consistency with the direction of the stimulation and was proportionate to the intensity, it is thought to be a useful method for assessing otolith functions.

Background and Objectives:In general, for surgical treatment of septal perforation, a suture repair method is necessary for atleast unilateral intranasal mucosal flap with the interposition of a connective tissue graft. However, autologous graft material issometimes insufficient when septal perforation repair is combined with other surgery such as rhinoplasty. The aims of this studywere to introduce a new repair technique of septal perforation using silastic sheet and to assess the usefulness of the new method.Subjects and Method:Between March 2003 and September 2004, 5 patients underwent septal perforation repair using silasticsheet with open rhinoplasty at the same time. Size and causes of septal perforation, symptoms, and complication were evaluatedby endoscopic examination and questionnaires pre- and postoperatively. Results:The causes of septal perforation were previousseptoplasty (3 cases), syphilis (1 case) and unknown (1 case). Preoperative symptoms including nasal obstruction, rhinorrhea,epistaxis and dryness were all improved postoperatively. The perforations of all patients were 1.0 cm sized or more indiameter. Four of five patients (80%) achieved complete closure and one patient had an incomplete closure after a mean followup of 16 months. Conclusion:The repair of septal perforation using silastic sheets is a very useful technique when the size ofseptal perforation is more than 1 cm large in diameter or when the autograft material is insufficient.

Background & Objectives:To predict postoperative pulmonary complication in patients with conservative laryngectomy, variable factors such as pulmonary function test (PFT) have been reported. Therefore, we reviewed the relationships between postoperative pulmonary complications and preoperative risk factors including the parameters of PFT. Patients & Method: From 1997 Jun. to 2005 July., conservative laryngectomy was performed under diagnosis of laryngeal cancer in 36 patients. The factors related to age, history of lung diseases, the parameters of PFT (FEV1, FEV1/FVC and FVC), and the types of surgery were analyzed to evaluate the postoperative pulmonary complication. We used a retrospective analysis of medical records and Fisher exact method to verify the relationships between preoperative risk factors and the pulmonary complications. Results:8 patients had postoperative pulmonary complication. Age, history of lung diseases and PFT parameters had no statistical significance. Among them, 7 patients and 1 patient had takensupracricoid laryngectomy and supraglottic laryngectomy, respectively. Supracricoid laryngectomy cases had more significant postoperative pulmonary complications than vertical partial laryngectomy cases. Conclusion:Age, the history of lung diseases, and parameters of PFT had no predictable value for postoperative lung complications. In the comparison between the surgery types, only supracricoid laryngectomy cases had statistical increase of postoperative pulmonary complications.. (Korean J Otolaryngol 2006;49:319-22)

Background and Objectives:We assessed olfactory function change in patients with chronic sinusitis who received endoscopic sinus surgery. By comparing the olfactory test results of two different age groups, we determined whether age affected postoperative olfactory function. Subjects and Method:Twenty patients with chronic sinusitis (2 age groups, with 10 patients in the forties and 10 patients in the seventies), who underwent endoscopic sinus surgery were selected. We used preoperative OMU CT and nasal endoscopy examination to evaluate the severity of sinusitis and polyp. Preoperative and postoperative nasal symptoms were assessed by questionnaires. The improvement of olfactory function after endoscopic sinus surgery was evaluated by olfactory function tests (T & T olfactometer and CCCRC test) preoperatively and postoperatively. Results:There was no significant difference in the severity of chronic sinusitis in both groups. Significant improvement of olfactory function was seen in both groups. There was no significant differences in the improvement of olfactory function between younger and older groups. Conclusion:Though old aged patients with chronic sinusitis have olfactory dysfunction, active surgical treatment is effective in the improvement of olfactory function.
