Background: Cardiac tamponade results in a hemodynamic disorder associated with decreased cardiac output and blood pressure. To improve cardiac output in a subject with cardiac tamponade, cardiotonic drugs and vasodilators with blood volume expander can be used. The purpose of this study was to observe the hemodynamic effects of cardiotonic drugs and vasodilators following administration of plasma expander in the dogs with cardiac tamponade. Method: Three groups of dogs were studied during the induced cardiac tamponade. Following infusion of pentastarch, group I received dobutamine by dripping of 10 microg/kg/min, followed by injection of 20 microg/kg/min, group II received hydralazine (20 mg, 40 mg) and group III received sodium nitroprusside (5 microg/kg/min, 10 microg/kg/min). The heart rate, blood pressure, cardiac output and pulmonary arterial occluded pressure were measured. The atrial transmural pressure was calculated by subtracting intrapericardial pressure from mean atrial pressure. Results: Cardiac output was increased in the groups I and II, but mean arterial pressure was increased in only the group I. Atrial transmural pressure was not changed in all three groups. Conclusion: The most pronounced hemodynamic improvements during the cardiac tamponade is observed in group I with pentastarch-dobutamine combination.

A 62-year-old male was admitted for evaluation of a mass shadow on chest film. Chest PA showed 7×5cm lobulated homogenous mass in right upper medial area of lung. On chest computed tomography, there was a Barge irregularly lobulated mass with central necrotic low density area in apical segment of right upper lobe. Right upper lobectomy of the lung was performed. Partial adhesion to parietal pleura of posterior mediastinum and severe adhesion to right upper apicoposterior segment was found during the operation Microscopic and ultrastructural studies(including immunocytochemical stains) of the mass revealed malignant fibrous histiocytoma.

Eight patients in the state of ASA classification l, ll were investigate. Blood samples were collected before, just after, 30 minutes after and 60 minutes after induction of anesthesia. Glucose and electrolyte changes in relation to maintenance fluids in balanced and halothane anesthesia were as follows. 1) In both anesthetic techniques blood sugar level showed increasing tendency according to duration of anesthesia. 2) There were no specific changes in serum electrolytes related to type of anesthesia. 3) The administration of D/S and H/D showed a little increase in Na+ and Cl- level compared to the administration of just DsW. 4) The administration of H/d showed less increase in K+ level than the administration of DsW or D/S. 5) Just after induction of anesthesia the K+ level increased a little and decreased gradually thereafter.

Broncho-gastric fistula caused by benign gastric ulcer perforation after esophagectomy is very rare. In general anesthesia of a patient with broncho-gastric fistula, in spite of hyperventilation, leakage of the anesthetic gases through fistula may make the patient hypercapneic, and positive pressure ventilation may increase the risk of the pulmanary aspiration by the regurgitation of gastric fluid by stomach distension. For that reason, in this patient, denitrogenation was performed during patient's voluntary respiration with 100% oxygen for 5 minutes, and induction was performed without positive pressure ventilation, and one lung ventilation was carried out. Hypoxemia was followed by one lung ventilation because his pulmonary function was moderate obstructive type and his lung was damaged by aspiration of gastric fluid via broncho-gastric fistula. A low level of continuous positive airway pressure (CPAP) has no significant hemodynamic effect and can maintain the patency of nonventilated lung, so hypoxemia induced by one lung ventilation may be reduced. Thus we carried out one lung ventilation with CPAP (10 cmH2O) in nonventilated lung and blocked broncho-gastric fistula with a bronchial blocker for prevention of both regurgitation of gastric fluid and leakage of anesthetic gases. One lung anesthesia was performed without any problem in this case.

The authors report seven cases of carotid-ophthalmic artery aneurysms who were surgically treated using the combined extradural-intradural or intradural approach from March, 1991, to December, 1993. Carotid-ophthalmic artery aneurysms are of considerably surgical interest because some of these were considered to have technical difficulties of clipping and disastrous surgical results. Removal of the anterior clinoid process and unroofing of the optic canal are the key points to exposure the operative field adequately. On the basis of these experiences, authors concluded that this approach is very useful, because of adequate surgical field and better mobilization of the internal carotid artery and optic nerve for direct clipping of carotid-ophthalmic artery aneurysm and basilar tip aneurysm.

Cisternography is isotopic demonstration of CSF dynamics, CSF rate & pathways, by scintillation scanning of the head after intrathecal administration of RISA. We have investigated the cisternographic findings in the hydrocephalus patients in view of the diagnosis and prognostic criteria. Cisternography provides the etiology & classification of hydrocephalus and reliable indication of CSF shunt operation. We found correlation between prolonged ventricular retention, delayed migration, inadequate clearance of the isotope and favorable response to shunting.

BACKGROUND: Mycosis fungoides(MF) is a form of cutaneous T cell lymphoma with clonal differentiation of helpr' T cell. It has a patch, plaque, and tumor stage. But pathogenetic factors controlling the development and progression of MF are still unclear. Apoptosis plays a major role in developmental biology and homeostasis. The bcl-2 oncogene prolongs ce11 life by inhibiting apoptosis. The mutant pS3 gene induces apoptosis indirectly. Ki-67 antigen is the cell proliferation marker. Recently, it has been shown that the relationships among them are important in the tumorigenesis of the various tumors. OBJECTIVE: The aim of this study was to examine the expression of these genes and apoptotic rate and clarify the relationship among them in the development and progression of MF. METHODS: The eighteen specimens from 8 patients with MF and 10 specimens from benign lymphocytic infiltrating diseases including 5 lichen planus, 3 lupus erythematosus, and 2 contact dermatitis were included. We performed immunoperoxidase staining(LSAB technique) using monoclonal antibodies including bc1-2, p~53, and Ki-67(MIB1). We used ApoptaqTM(Oncor) in situ labelling kit for detecting apoptotic cell.
