It is easy to view the laryngeal aperature with a flexible fiberscope through a laryngeal mask airway (LMA). This is a case report that the LMA could facilitate a fiberscope-aided tracheal intubation easily. Patient was a 59 year old female who had some limitation of mouth opening due to ankylosis of bilateral temporomandibular joints. After thiopental (200 mg) and succinylcholine chloride (50 mg) were given intravenously, a number 3 sized LMA was inserted and the lungs were ventilated via the LMA. The anesthesia cirele system is then disconnected from the LMA and a fiberscope, with the proximal end jacketed with a well-lubricated, cuffless, 6-mm-ID endotracheal tube (ETT); was inserted into the trachea through the lumen of the LMA. The 6-mm-ID ETT was threaded over the fiberscope into the trachea before fiberscope was withdrawn, and a traeheal tube exchanger was inserted through the ETT after enough ventilation for a while, followed withdrawal of the LMA and ETT. Finally, we can make the 7 mm-ID ETT with cuff insert into the trachea over a tracheal tube exchanger very easily without any difficulties.

PURPOSE: To compare the clinical and radiological findings of orbital pseudotumor with those of orbital lymphoma. MATERIALS AND METHODS: The clinical and radiological features of 12 orbital pseudotumors were compared with those of 17 orbital lymphomas, the nature of all lesions being confirmed by tissue biopsy. Twenty-four CT scans and nine MR images were retrospectively reviewed and compared, with special focus on the location of a tumor in the orbit, the invasion of periorbital structures, tumor margin, bilaterality, and signal intensity. The initial symptoms at admission were also classified and compared. RESULTS: In 50% of cases, orbital pseudotumors were located in both extraconal and intraconal space; 75% involved two or more extraocular muscles, and 33% involved the optic nerve. Margins were either infiltrative (75%) or ill-defined (92%). As for orbital lymphomas, 64% occupied extraconal space, invading one or less extraocular muscle (76%) and conjunctiva (29%). Seventy-one percent had a sharp margin, and 65% were lobulated or round. In pseudotumors, orbital pain and visual loss were major symptoms, while in lymphomas a painless orbital mass was the initial symptom. CONCLUSION: CT or MR image analysis of lesion location, margin, and the involvement of adjacent extra-ocular muscle or optic nerves may help differentiate between orbital lymphoma and orbital pseudo tumor.

The purpose of the present study is to measure the viscosity of liquid in the capillary tube viscometer using the unsteady flow concept. The capillary tube viscometer is consisted of a small cylindrical reservoir, capillary tubes, and the mass flow rate measuring system interfaced with computer. Two capillary tubes with 1.152 and 3.002 mm (inner diameter) are used to determine the diameter effects on the viscosity measurements. The instantaneous shear rate and gravitational driving force in the capillary tube are determined by measuring the mass flow rate through the capillary tube instantaneously. The measured viscosities of water and aqueous Separan solution as the blood analogue fluid are in good agreement with the reported experimental data.

The nuclear accumulation of p53 protein is known to correspond with mutation of p53 tumor supressor gene. To investigate the relationsbip between clinico-pathologic features and expression of p53 mutations, 65 cases of primary cervical carcinoma were analysed by an immunohistochemieal method using monoclonal antibody of p53. Immunostaining demonstrated varioua nuclear stinings of cancer cells in 48.4% of squamous cell carcinoma(51.9% in large cell carcinoma and 25.0% in small cell carcinomas) and 23.5% of adenocarcinoma(p<0.05) No differences in clinical stage and p53 positivity were found. There was no significant correlation between p53 positive cases and status of recurrence. This data suggests that p53 protein is not correlated with the disease progression and prognosis.

Chylous ascites is extravasation of lymphatic fluid and retention in the peritoneal cavity due to traurna or obstruction of the lymphatic system. Chylous ascites is very rare complication of Continuous Ambulatory Peritoneal Dialysis (CAPD) and is associated with trauma to the lymphatics during catheter insertion in the early stage of CAPD and repeated mild trauma to the lyrnphatics during longterm dialysis. Chylous ascites in the CAPD is suspected when the drained peritoneal fluid is milky white and confirmed by demonstration of the specific components of chyle, such as elevated triglyceride and low cholesterol than plasma and should be differentiated from pseudochyle and bacterial peritonitis. We report a case of chylous ascites in a patient undergoing CAPD at 2 months later of initiation of CAPD, which was not improved by conservative management. So CAPD catheter was removed and renal replacement therapy was changed to hemodialysis.

The objective of the present study is to obtain information on the hemodynamic characteristics in the anastomotic sites of femoral artery through the vascular implantation. Three dimensional steady and physiological blood flows in the femoral artery are simulated using the finite volume method. The geometrical shape of the anastomotic sites is made based on the vascular anatomy of a white rabbit. Wall shear stress distributions in the anastomotic sites for the physiological flow are compared with those for steady flow. Blood flow phenomena in the anastomotic sites of the femoral artery are discussed extensively.

Asthma is a common medical syndrome which significantly increases the morbidity and mortality of surgical and anesthetic procedures. The anesthesiologist should be closely involved in the preoperative assessment and Prep-aration of these patients for, surgery and anesthesia and should be continually aware of the possibility of bronchospasm. The safe clinical management of this challenging population group demands not only expertise in carefully planning an anesthetic technique best suited to an individual patient and his specific disease process. We reported a case of bronchospasm after injection of neostigmine intravenously in 34-rear old female patient during endotracheal general inhalation anesthesia, together with brief of review of literature.
