Transient hyperkalemia has been reported to occur in eletric burn patients following intravenous administration of succinylcholine. We have studied the origin of the elevated serum K+ concentration after injection of succinylcholine from both the non-burned area and from the burned area in electirc burn patients. Blood samples for serum K+ measurement were drawn 1,2,3,4,5 and 10 minutes after administration of succinylcholine from both the burned are and the non-burned area in 6 electric burn patients. The following results were obtained: 1) Serum K+ levels increased in the burned group in 3 minutes after injection of succinylcholine. 2) The serum K+ concentration of venous samples from the electric burn area were more increased than from the non-burned area injection of succinylcholine.

We describe a case of an acute heart transplant rejection treated with triple immunosuppression and plasmapheresis, resulting in evidence of improved clinical manifestation and hemodynamics. This case suggests that plasmapheresis may be useful in the treatment of possible acute humoral(vascular) rejection in heart transplantation.

Injuries of the posterior cruciate ligament have almost universally been treated nonoperatively in the past due to indignity of this complex structure. Recent studies have shown new informations on the anantomical, histological, biomechanical characteristics of the Posterior cruciate ligament PCL), and thereby interest of reconstruction surgery is increasing. But intraarticular PCL reconstruction still remains one of the most challenging problems in knee surgery. Although, various types of graft and surgical techniques have been used for reconstruction, results of surgery has been variable. In this study, three different methods of graft fixation for PCL reconstruction are evaluated biomechanically to determine the effect on mechanical property of reconstructed PCL using 30 porcine knees. Grafts used in this study were bone-patellar tendon-bone fixed with interference screw and Achilles tendon tied with suture. Additionally, five original PCLs were also tested by Instron universal testing instrument to determine its mechanical proprety. Tensile test was performed at extended knee position. It was demonstrated that mechanical strength of bone-patellar tendon-bone graft is superior to that of Achilles tendon graft. All of the failures of bone-patellar tendon-bone graft and Achilles tendon graft occurred at tibial fixation site whereas original PCLs which failed at proximal midsubstance of ligament. In conclusion, tensile strength of Bone-patellar tendon-bone graft used for PCL reconstruction is higher than that of Achilles tendon but latter can be used in terms of as clinical meanings.

Syphilis was known to be generalized disease and it had been decreased until 1960's. But, it has been increased again recently. The author analysed the 22 cases of congenital syphilis which were treated at department of orthopaedic surgery at Ewha Womans University Hospital from Jan. 1979 to July 1983 and the following results were obtained. 1. There were no significant changes of the number of patient by years. 2. Common symptom and sign were hepatosplenomegaly(84%), fever(62%) and skin changes(50%), and pseudoparalysis was observed in one case. 3. Radiologic bone changes were observed in 11 cases (50%) and the following results were obtained: a. Below the two week old, there was relatively low incidence of bone change with 22%. b. There was high incidence of bone change in prematurity with 75%. c. Common features of bone changes were periosteal reaction, osteochondritis and metaphysitis (91%). Pathologic fracture was observed. in one case. 4. Although we have observed the bone changes only in 50% of cases, all the other reports has reported more than 80% and we thought that radiologic bone change would aid the diagnosis of congenital syphilis.

In order to investigate the efficacy and safety of oral fosinopril, a new phosphorus containing angiotensin converting enzyme inhibitor, a single dose of 10 to 20mg was administered in 23 hypertensive patients with diastotic blood pressure above 95mmHg and all other anti-hypertensive agents were not administered during 4 weeks of study. Blood pressure and heart rate were measured on the 2nd and 4th week of therapy. The complete blood count with platelet count, blood chemistry by SMA-12 and serum electrolytes were performed at the begining and 4th week of therapy. The urinalysis and electrocardiography were performed at the beginning and 4th week of therapy. Any kinds of side effects were actively questioned by the examining physicians. The following results were obtained : 1) At the beginning and 4th weeks of therapy, the average systolic and diastolic pressure were 170.0+/-17.6/101.6+/-6.1mmHg, 142.7+/-15.1/87.3+/-6.7mmHg respectively. The systolic and diastolic blood pressure were declined statistically significantly(p<0.05) throughout the period of treatment and diastolic blood pressure of all subjects except 3 patients(86%) was maintained below 90mmHg after 4th week of treatment. 2) There was no significant change in the pulse rate before and after therapy. 3) There were no significant changes in blood chemistry, serum electrolytes, hematologic findings, urinalysis and electrocardiographic findigns. 4) side effect were developed in 5 patients(23%) with dry cough, 3 patients(13%) with headache and 2 patients with facial edema but side effects were mostly mild in nature without potenitally serious episodes. These results suggested that antihypertensive therapy with onec-daily fosinopril was effective and well tolerated in essential hypertensive patients.

This preliminary study was intended to clarify the effect of intraoperative fluid therapy on Acid-Base balance of the use of Hartmann's solution and 5% Dextrose solution. The arterial carbon dioxide partial pressure and oxygen partial pressure and pH are basic indices of the adequacy of ventilation in anesthetized patients, respiratory care and intensive care. In order to achieve this goal, the data collections were done at the Department of Anesthesia in Hanil Hospital from Mar., 1980 to Aug., 1980. The samplings, 20 cases, were included A.S.A. class I and II. We used 1,500 to 1,800cc/2hrs. of Hartmann's solution and 1,000cc/2hrs, of 5% Dextrose solution each 10 patients through the operative period. Observations were made for the followings; pH, PaCO2HCO-3. From the results of this study, there were no significant relationship between the use of 5% Dextrose solution and Hartmann's solution on Acid-Base balance during the intraoperative period.

Pulmonary thromboembolism (PTE) is a significant cause of death in the hospitalized patient in the western and developed countries. The development of PTE and venous thrombi is associated with many and various factors, including that physicians fail to provide adequate prophylaxis to the high risk patients. The authors studied 74 legal autopsy cases performed from 1996 to 2000 at the Headquarters of National Institute of Scientific Investigation, Seoul, Korea. We learned that ceasarian section was the most common precedong trauma in PTE death in legal cases. Excluding Ceasarian section cases, major mechanical injuries, male gender and aging were common factors associated with PTE. Obesity was a common factor in all kinds of trauma. Deep vein thrombi were documented in majority cases and ambulation was a critical triggering cause for the thrombi making PTE. Clinical diagnosis was not so satisfactory.

BACKGROUNDS: Gamma band oscillatory activity is considered to be related to congnitive functions and illustrates that the concept of event-related oscillations bridges the gap between single neurons and neural assemblies. An event-related gamma oscillation is the time - locked responses of specific frequency, and can be identified by computing the amplitude frequency characteristics of the averaged event-related potentials(ERPs) after stimulation. OBJECTIVES: We purposed to present experimental paradigm to investigate @-band oscillation activities from the recording of ERPs by using auditory oddball paradigm and investigate the difference of @-band activity between schizophrenia and normal controls. METHODS: The ERPs resulting from auditory stimuli with oddball paradigm in a group of schizophrenics(n=11) and also a group of age-, sex- and handedness matched normal controls, were recorded by 128 channel EEG. The @-band oscillatory activities were calculated by using time-frequency wavelet decomposition of the signal between 20 and 80Hz. The @-band oscillatory activities of both groups were compared by t-test. RESULTS: The @-band oscillatory of the leads Fz,Gz and Pz of both groups were represented well in the time - frequency maps. Significant increases of the @-band activity in normal controls compared with schizophrenics were observed around 160 msec. 350msec. and 800 msec after stimulation. CONCLUSIONS: Our results suggested that the increment in @-band oscillatory activity during cognitive operations and decreased @-band activity in schizophrenics may be associated with the cognitive dysfunctions and the pathophyiology of the schizophrenia.
