Dynamic cardiomyoplasty is a recently introduced surgical method to improve myocardial performance. It consists of a placement of a skeletal muscle flap around the heart and stimulation of the flap in synchrony with ventricular contraction. We experienced a case of cardiomyoplasty in a 25 year old male patient with congestive heart failure. Anesthesia was induced and maintained with fentanyl, midazolam and isoflurane. The operation was performed for 8hrs without cardiopulmonary bypass and the patient was transferred to the intensive care unit. He was mechanically ventilated electively overnight and extubation was done 18hrs postoperatively. The patient was discharged home on the 40days after operation and improved in exercise tolerance. We report the anesthetic management and hemodynamic changes in a patient who underwent dynamic cardiomyoplasty.

Coronary artery bypass grafting (CABG) without extracorporeal circulation (ECC) is now an accepted technique of myocardial revascularization in selective cases of coronary arterial occlusive disease. We experienced a case of CABG without ECC in a 20 year old female patient with complete occlusion of the right coronary artery. Anesthesia was induced and maintained with fentanyl, midazolam and isoflurane. Nitroglycerine and dopamine were given to stabilize the hemodynamics during intra- and post-operative periods. And esmolol was administered with a loading dose of 30 mg over 1 min, followed by a continuous infusion of 50~100 g/kg/min to maintain the heart rate (50~60 beats/min) and systolic blood pressure (60~80 mmHg) during distal anastomosis. The patient was recovered uneventfully and discharged on the 8th postoperative day.

Jehovah,s Witnesses who require operation represent a challenge to the physician because of the patient,s refusal to accept blood transfusion. An orthotopic heart transplantation was succesfully performed in a 40-year old Jehovah,s Witness without use of any blood product. During the operation, cell saver was used for shed blood and aprotinin was administered intravenously. The use of blood conserving methods, meticulous operative technique and brisk postoperative diuresis has added to the efficacy of heart transplantation in this patient. Total postoperative drainage was 860 ml and the lowest hemoglobin level was 11.8 g%. The patient recovered uneventfully and discharged on the 60th postoperative day.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

BACKGROUND: It seems that herpes zoster is caused by reactivation of the varicella-zoster virus and its incidence is increasing. The reactivation of the varicella zoster virus is thought to be associated with the disturbance of the state of immunity in patients with herpes zoster. OBJECTIVE: The purpose of this study was to elucidate the state of immunity in patients with herpes zoster in its acute phase(less than 7 days). METHODS: 1. Thirty patients with acute phase herpes zoster matched by age and sex against a control group, were checked for Helper/Inducer T cell(CD4), Suppressor/Cytotoxic T cell(CD8), NK cell, B cell and activated T cell by three color flow cytometric analysis. 2. Forty patients with herpes zoster measured delayed cutaneous hypersensitivity by means of Multitest' CMI. 3. Thirty patients with herpes zoster measured Ig G, M, A by means of N-antisera method.

Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as a result of partial or complete obstruction of the bile duct, and may manifest clinically severe from of disease, rapidly deterioration to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying causes were 12 benign diseases(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis (n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients improvement of general condition and failed in three patients. The procedures were preterminated due to the patient's condition in two and biliary-porto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggests that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment.

OBJECTIVE: Cartoons have been known to motivate learners and make learning process easier by combining verbal and visual effects. But they are mostly applied to motivate the less able learners, and have limits in delivering comprehensive information. Thus, more careful and scientific validation for the pros and cons of using cartoons for everyday use in various subjects is in need. METHODS: In this research, we used Electroencephalography(EEG) to compare cartoon learning and text learning by measuring four characteristic brainwaves including theta, alpha, sensory motor rhythms(SMR), and beta, from the left and right brain. The EEG signals acquired from 24 subjects are analyzed using the mean difference of the left and right brain and canonical correlation analysis. RESULTS: The theta brainwave of the left brain and right brain shows significant differences (p<0.05) from cartoon learning versus text learning in the theta brainwave while the other brain waves show similar patterns. CONCLUSION: Cartoon learning produced significantly stronger theta brainwaves than text learning implicating that cartoon learning reduces more focused attention, SMR brainwaves and beta brainwaves from the left brain explained cartoon learning and text learning process while alpha brainwaves explained those processes in the right brain.
