A Clinical observation was made on five patients with ruptured aortic sinus of Valsalva who visited Seoul National university hospital during the period of May, 1975~Jan., 1980. 1. Age distribution was from 19 to 32 years and four patients were male and the rest one case was female. 2. Chief complaints on admission were dyspnea in 3 cases and chest pain in 2 cases. Onset of symptoms was abrupt in 4 cases. 3. Continuous murmur was heard at third and fourth intercostal space along left sternal border with thrill in all cases. 4. Cardiac catheterization and aortography showed regurgitant flow from aorta to right ventricle in all cases. 5. Operation was done successfully in 3 cases, of which aortic insufficiency was persistent in one case.

Sex distribution was 5 male and 3 female patients. 2. Age distribution was from 16 to 39 years and the mean age was 24 years. 3. Symptoms were exertional dyspnea in all cases, cyanosis in 3 cases. Other symptoms were palpitation, chest pain, growth retardation and chest deformity. Duration of illness was from 6 to 16 years and N.Y.H.A. functional class was between II and III. 4. On physical examination, cardiac mumurs were heard in all cases. Cyanosis on the lips and nail beds were noticed in 3 cases and clubbing of fingers was seen in 1 case. 5. Situs inversus was noticed in 1 case, mesocardia in 3 cases, dextrocardia in 1 cases and right sided aortic arch in 1 case by simple Chest PA. 6. Electrocardiographic findings were Biventricular hypertrophy in 3 cases, Left ventricular hypertrophy in 2 cases, Right ventricular hypertrophy in 2 cases and Incomplete right bundle branch block in 1 case. No arrhythmias were observed. Septal Qwave was not observed on the left precordial leads in all cases. 7. CTGA were suspected or diagnosed by Echocardiography in 7 cases. 8. The diagnosis of CTGA and its associated anomalies were confirmed in all cases by cardiac catheterization and angiocardiography. There were one case of I.D.D. type CTGA and seven cases of S.L.L. type CTGA's. Associated anomalies were ventricular septal defect in 5 cases, pulmonary stenosis in 5 cases, patent foramen ovale in 3 cases, atrial septal defect in 2 cases, patent ductus arteriosus in 1 case, dextrocardia in 1 case, left sided A.V. valve regurtation in 2 cases, and right sided aortic arch in 1 case. 9. Operation was done in the case associated with patent ductus arteriosus, and corrective surgery was done in the another case associated with ASD, VSD, PS and TR with C-TGA.

PURPOSE: The purpose of the present study was to define the factors that affect the treatment and clinical result of displaced calcaneal fracture with use of the pre- operative and final follow-up computed tomography scanning. MATERIALS AND METHODS: Present study included the 17 patients(18 feet) whom we performed surgery for displaced intra-articular calcaneal fracture at our institution between March 2000 and March 2002 and had a minimum follow-up of 12 months. For all patients, the Bohler's angle and posterior facet incongruity were measured with computed tomography pre- and post-operatively. The Creighton-Nebraska Health Foundation Assessment Scale for Fractures of the Calcaneus (CN scale) was used to evaluate the clinical results. RESULTS: Of all eighteen fractures, the clinical results were excellent in three (16.6%), good in six (33.3%), fair in six (33.3%), and poor in three (16.6%). The Bohler's angle averaged 21degrees, 15degrees, 27degrees, 25degrees at final follow-up in each above clinical result group. The step-off averaged 1.0, 1.6, 3.9 and 6.0 mm and the average range of motion of the subtalar joint at final follow-up were 85, 76, 60 and 45% of normal. CT evaluation showed intra-articular screws in the posterior subtalar joint in three (16.6%) of the eighteen fractures but their average clinical result was good (80.3 points). CONCLUSION: The restoration of the congruity and range of motion of posterior subtalar joint are considered important factor that affect clinical result.

BACKGROUND: It has been known that Ginseng extract causes the hypotensive action while it rather produces the hypertensive action. Some studies have suggested that Ginseng extract causes a biphasic response on blood pressure, namely, transient fall followed by prolonged elevation. It has been also shown that administration of Korean Red Ginseng powder has no effect on blood pressure in normotensive and hypertensive rats. The present study was designed to examine the effect of total Ginseng saponin on contractile responses of vasoconstrictors in the rat aorta and to establish the mechanism of its action. METHODS: The ring segment of aorta was mounted in a muscle bath filled with oxygenated Krebs solution for the measurement of isometric tension. After the equilibration period, under the presence of total Ginseng saponin, isometric tension induced by some vasoconstrictors were observed and compared to the control responses. The data were expressed as % of the control tension. RESULTS: Phenylephrine (an adrenergic alpha1-receptor agonist) and high potassium (a membrane depolarizing agent) caused greatly contractile responses in the rat aorta, respectively. However, in the presence of total ginseng saponin (600 g/ml), the contractile responses of phenylephrine (10(-6) and 10(-5) M) and high potassium (3.5 x 10(-2) and 5.6 x 10(-2) M) were markedly potentiated whereas prostglandin F2alpha(5 x 10(-6) M)-induced contractile responses was not affected. The contractile responses induced by phenylephrine (10(-5) M) and high potassium (3.5 x 10(-2) M) even under the presence of total ginseng saponin (600 g/ml) were greatly inhibited by the pretreatment of nicardipine (10(-6) M), a calcium channel blocker. CONCLUSION: Taken together, these experimental results suggest that total ginseng saponin can enhance the contractile responses evoked by stimulation of adrenergic alpha1-receptor and the membrane depolarization in the isolated rat aortic strips, which seems to be associated to calcium influx.

OBJECTS: The purpose of this study was to investigate the effects of cognitive differentiation training program-Korean version(a training program of attention and conceptual abilities) on cognitive function, psychopathology and problem solving skills in patients with schizophrenia. METHODS: A total of patients diagnosed as schizophrenia using DSM-IV were randomly assigned to 2 groups. The training group went through a total of 22 sessions of cognitive differentiation training (60min/sessionX2sessions/wkX11wks). The attention-placebo control group received psychoeducation program during the same period. Arithmetic, vocabulary, similarities, picture completion of Wechsler Adult Intelligence Scale-Korean version, Positive and Negative Syndrome Scale, and Social Problem Solving Scales were administered to all patients, both before and after the training program. RESULTS: In the arithmetic scores(F=6.35, af=1, p=0.018) of Wechsler Adult Intelligence Scale-Korean version, and total scores(F=6.35, af=1, p=0.018) and problem solving skill scale scores (F=4.88, af=1, p=0.036) of social problem solving scale, interaction effects of training was significant. CONCLUSION: Our findings suggest that cognitive differentiation training program-Korean version is effective on improving auditory attention and problem solving skills in patients with schizophrenia.
