Patients with severe congestive heart failure due to rheumatic heart disease generally have both reduced cardiac output and increased pulmonary and systemic venous pressures. A study was therefore made of the use of vasodilator therapy with orally administered hydralazine, which acts on arteriolar resistance vessels and thus reduces afterload. 55 children aged from 4 years old to 15 year old were divided into two groups. Group I received oral hydralazine(4mg/kg/kay in 4 divided doses) in addition to digoxin therapy for mean duration of 10.5 months. Group II received oral digoxin only. The hemodynamic results using M-mode echocardiography, chest X-ray, and EKG between two groups were analyzed. 1) 4(78%) of 55 patients had only mitral valve involvement and another 12 patients had double valve involvement and all the patients belonged to functional class III or IV fo New York heart Association. 2) Left venticular end-diastolic dimensions and the height of R in V6 on EKG were not changed significantly in both groups. 3) Shortening fraction, LPEP/LVET, and RPEP/RVET were markedly improved in both groups, but the degree of improvement in group I was more significant than in group II. 4) 21(80%) of 26 patients in group I showed significant improvement in functional class(t=1.92, 0.05

Doppler echocardiography was performed to evaluate the tricuspid regurgitation in 786 infants and children with heart disease. 3 Doppler methods were used. : The duration of systolic turbulence of tricuspid regurgitation in thr right atrium was evaluated by continuous wave Doppler method, the distance of systolic turbulence within right atrium from the tricuspid plane, by pulsed Doppler method and the retrograde systolic hepatic vein regurgitation, by color Doppler method. The following results were obtained. 1) Incidence of pan systolic tricuspid regurgitation in each disease were as follows. 68% of ECD, 66% of Ebstein's anomaly, 54% of pulmonary atresia, 50% of arrhythmia, 45% of ASD, 38% of TAPVR, 15% of VSD, 26% of TOF, 12% of PDA, 13% of normal children. 2) In about 90% of children with tricuspid regurgitation, hepatic vein regurgitation was detected by color Doppler echocardiography.

Morquio's syndrome is a very rare disease, which is characterized by dwarfism, flattening of the vertebral body, marked spinal kyphosis, widespread affection of the epiphyses and normal intelligence. The authors experienced a case of Morquio's syndrome with typical clinical and radiological findings. The patient underwent bilateral supracondylar varus osteotomies for severe genu valgum deformities.

We reviewed thrity-one cases of unstable tibial fractures treated with Ilizarov method from January 1991 to December 1992. We attained satisfactory bony union in all cases without bone graft(Average time 19.2 weeks). There were numbers of complications, but its were soluble and careful management & numbers of minor surgery were needed to prevent & solve such complications. Post-op immediate weight bearing and ROM exercise were possible and showed no difficulty in getting mainteance of reduction & fracture healing, and serious joint ankylosis was not developed. In conclusions, Ilizarov method is an excellent treatment in getting reduction, maintenance of reduction, early ambulation and fracture healing in the cases of unstable tibia fractures.

With simple abdomen, double contrast colon study, and ultrasongraphy, authors retrospectively analyzedradilogic findings of 46 cases which were proved periappendiceal abscess, due to perforation of appendix, byhistology or follow-up ultrasnongraphy from May in 1983 to July in 1985 at Yeung-Nam University Hospital. Theresuls obtained were as follows: 1. Of 46 cases, 24 cases were males and 22 cases females, with the results ofabove statistics, periappendiceal abscess was not influenced by sex. 2. Periappendiceal abscess was mostfrequently demonstrated in forties. 3. Comparison of ultrasonography and B.E. Pseudorenal pattern(Ultrasonography)- well defined defect (B.E.) Cystic pattern(Ultrasonography)- serrated defect (B.E.) 4. Missed 2 cases inultrasonography were detected in B.E., i.e. sensitivity of B.E. is higher than that of ultrasonography. 5.Differences of ultrasonography and B.E.

Soft tissue coverage of heel defects has long been a difficult problem. In 1982, Iron reported eight cases of heel defects in children using an ipsilateral posterior thigh flap with use of the Hoff-man's skeletal fixation apparatus for immobilization. We report three cases of heel defects treatment in children using ipsilateral posterior thigh flap and detach flap in an average 13 days with aid of single photon emission computed tomography(SPECT) for evaluation of circulation status of flap.

Cardiac myxoma is a rare but potentially treatable cause of stroke. The diagnosis is rarely made on typical triad of constitutional, embolic, and obstructive symptoms, and it is difficult because there is no specific history, physical examination, chest X-ray, or electrocardiographic findings, but with the development of echocardiography the correct diagosis is now usualy made. Neurologic manifestation is frequent(25-45%) and presented with embolic infarction, aneurysm formation, intracranial hemorrhage, and distant metastasis. We experienced five patients with cardiac myxoma who presented with these neurologic manifestations. Also we should be considered in the differential diagnosis of cerebral infarction, particularly when multiple cerebral infarction and constitutional or obstructive symptoms are conjoined in young age stroke. We describe five patients who presented with embolic infarction, cerebral metastasis and aneurysm formation.

BACKGROUND:Acute seizures that increase neuronal activity cause a rapid and transient induction of the immmediate early c-fos in specific brain regions. C-fos gene may mediate long-term changes in cell function, such as growth, differeniation, and development, in response to acute extracellular stimulation. This study is designed to compare the expression of Fos protein in hippocampus after single and repeated injections of kainic acid (KA). METHODS:In KA-single injection model, twelve adult male Sprague-Dawley rats were treated with single intraperitoneal injection of convulsive dose(20-30 mg/kg) of KA, and. in KA-multiple injections model, seven rats received KA by repeated daily intraperitoneal injections for 15 days. Eight control rats received normal saline. Expression of Fos protein was tested in hippocampus by immunohistochemical staining, and was scored by the degree of staining intensity and the ratio of stained cells to tested ones. RESULTS:The scores tended to increase in CA3 and dentate gyrus were significantly higher in KA-single injection model than in control (p<0.05). In comparison with scores in KA-model. CONCLUSION:These results show that repeated seizure produces some blockade of c-fos induction in CA2, CA3 and dentate gyrus. This may be a long-term adaptive response by the nervous system to repated neuronal activation
