To assess the likelihood of procedural success in patients with multivessel coronary artery disease, 46 consecutive patients (male 34, female 12, mean age 60+/-9 years) umderwent single or multiple site angioplasty. The clinical diagnosis of unstable angina was in 20(44%), stable angina in 10 and acute or old myocardial infarction in 16. Coronary angiographic findings of 2 vessel disease was in 38(83%), triple vessel disease in 8. Left ventricular function was generally well preserved (mean ejection fraction 65+/-12%, range 30-82%) and mean 2.0 stenosis per patient angic, lasty had attempted. Single vessel angioplasty (SVA) was performed in 13 and multivessel angioplasty (MVA) in 33. Procedural success was achieved in 79(86%) out of total 92 stenoses. Sixty-six(88%) out of 75 stenoses in MVA and 13(76%) out of 17 stenoses in SVA had procedural success respectively. According to angiographic morphology of lesions, procedural success of type A stenoses was 17/17(100%), type B stenoses 57/66(86%) and type C stenoses was 5/9(33%). In 13 failures included inability to pass the guide wire cross the lesion in 7, inability to guide the griding catheter in 2 and inability to dilate lesions in 4. Before and after angioplasty, treadmill test (modified Bruce protocol)could be performed in 29 patients. Total duration of exercise and maximal double product improved significantly from 8.5+/-2.3 minute 5188+/-2403 to 12.2+1.3 min., 23,062+/-4111 respectively (p<0.001). 17 out of 24 patients who had positive treadmill test before angioplasty showed negative conversion after procedure. Complications included dissection in 29, prolongd chest pain in 5, acute closure in 3, cardiac tamponade in 1 and ventricular fibrillation due to side branch oclusion in 1. Thus, coronary angioplasty in selected paients with multivessel coronary artery disease might be useful and have relatively good immediate results, but the long-term efficacies with other forms of treatment must be evaluated prospectively.

Two cases of exercise-induced atrial fibrillation were diagnosed in 68 years old female and 47 years old male. They complained palpitation during exercise, and emotional upset for the last 5 years. There was no evidence of organic heart disease except mild hypertension in female patient. The atrial fibrillation was induced repeatedly by treadmill exercise test and intravenous infusion of isoproterenol. The beta blocker(atenolol 50mg po dialy) prevented the induction of atrial fibrillation during treadmill exercise. We report two cases of exercise-induced atrial fibrillation which is very rare and might be related to catecholamine.

OBJECTIVES: This study examined the prevalence of psychiatric problems in children with scholastic difficulties who had been referred for mental health services from the Office of Education in Ulsan Metropolitan City. METHODS: Child psychiatrists evaluated the referred children using the DSM-IV. Evaluation tools included the Wechsler Intelligence Scale for Children-III, the Children's Depression Inventory, the Korean form of the State-trait anxiety Inventory for children, the ADHD rating. RESULTS: Seventy-six children consisting of 64 boys (84.2%) and 12 girls (15.8%) participated in the study. The average age was 10.3 (SD=0.93) years old. Approximately 74% of the children referred for scholastic difficulties were diagnosed with mental retardation. The Axis I diagnosis among these children were ADHD (86.8%), depression (21.1%), learning disorder (9.2%), communication disorder (4.8%), pervasive developmental disorder (3.6%), internet addiction (1.3%), and mood disorder (1.3%). Their overall measure according to the Child Depression Inventory was 22.7 (SD=16.8), that for the State-Trait Anxiety Inventory for Children was 33.3 (SD=7.9)/32.4 (SD=9.5), and that for the ADHD rating scale was 18.9 (SD=10.9). CONCLUSION: These results suggest that many children with scholastic difficulties have both complex psychiatric and educational problems.

PURPOSE: The purpose of this article is to show the efficacy of a bioabsorbable polylactide (PLA) screw for treating syndesmotic injuries of ankle fractures. MATERIALS AND METHODS: Ten patients who underwent an open reduction and internal fixation operation for ankle fractures that had syndesmotic injuries from Dec. 1992 to Feb. 1997 were enrolled into the study. There were 6 men and 4 women. The average age of the patients was 42.6 years and the average follow-up period was 2 years 7 months. The cases were analyzed by clinical and radiological findings at the time of their last follow-up evaluation. RESULTS: According to the clinical results, there was statistically no significant difference between finding an average of 15.8 degrees of dorsiflexion and 45.8 degrees of plantar flexion of the ankle on the affected side of the individuals and that of 17.8 degrees of dorsiflexion and 48.5 degrees of plantar flexion on their normal contralateral side. Upon radiological analysis, the medial clear space was decreased from 7.3+/-1.8 mm to 3.1+/-1.0 mm, the tibio-fibular clear space was decreased from 7.8+/-0.9 mm to 4.9+/-0.5 mm and the tibio-fibular overlap increased from 4.6+/-1.8 mm to 10.5+/-1.4 mm. Also there was no pain and instability in the affected side in any of the patients at the time of the last follow-up. CONCLUSION: A bioabsorbable PLA screw is a good implant for stabilizing syndesmotic injuries of the ankle fractures because there is no evidence of a significant osteolysis resulting around the implant, there is a gradual transfer of stress to the surrounding bone, and there is no requirement for a subsequent removal.

BACKGROUND: The kinetics of recovery oxygen consumption plays an important role in determining exercise capacity. This study was performed to evaluate the kinetics of recovery oxygen consumption and the effects of percutaneous balloon mitral valvuloplasty (PMV) and exercise training on the recovery kinetics in mitral stenosis (MS). METHOD: Thirty patients with MS (valve area 1.0 cm2) and thirty age-and size-matched healthy volunteers were included for this study. All subjects performed symptom-limited, upright, graded bicycle exercise. Patients were randomized to either the exercise training group or the non-training group after successful PMV (valve area 1.5 cm2 and mitral regurgitation grade 2). The exercise group performed daily exercise training for 3 months. RESULTS: Half-recovery time of peak oxygen consumption (T1/2VO2) was significantly delayed in MS patients than in the volunteers (12,042 sec vs 595, p<0.01). Peak oxygen consumption (pVO2, ml/min/kg) was significantly increased in both the training (16.84.9 to 25.36.9) and the non-training group (16.35.1 to 19.66.0) 3 months after PMV. T1/2VO2 was significantly shortened in the training group (12,439 to 7,613, p<0.01), but not in the non-training group (11,446 to 10,944 sec, p-0.12) at 3 months follow-up. The degrees of symptomatic improvement after PMV were more closely correlated with the changes of T1/2VO2 than those of pVO2. CONCLUSION: Kinetics of recovery oxygen consumption was markedly delayed in MS patients, but the kinetics improved after exercise training but not after PMV alone. These results suggest that adjunctive exercise training may be useful for improvement of recovery kinetics and subjective symptoms after PMV.

PURPOSE: To investigate the cytotoxic effect of rigid gas permeable(RGP) and reverse geometry lens(RGL) on rabbit corneal cells. METHODS: In 36 white rabbits, right eyes were worn with either RGP or RGL. Left eyes were served as control. The rabbits were sacrificed at 1, 3, 7, 14 days after fitting and 7, 14 days after removal. Morphological changes of the basal epithelial cells and stromal keratocytes were observed using the light and transmission electron microscopy. The samples were examined after TUNEL staining in 3 high power fields (x400). RESULTS: In control eyes, 2.26% of central corneal epithelial cells showed apoptosis. After RGP wearing, the epithelial apoptosis decreased by 0.32% compared to control eyes(2.17%) at 14 days(p<0.001), and returned to 1.55% at 14 days after lens removal(2.04% in control, p=0.161). After RGL wearing, the degree of apoptosis was also lower than control(3.22%) by 0.30% at 14 days(p=0.003). However, it increased to 0.75% at 14 days after lens removal(1.67% in control, p=0.077). A few TUNEL positive fibroblasts were found in superficial stroma in both RGP and RGL group, but not in control eyes. CONCLUSIONS: Both RGP and RGL wearing may decrease the degree of apoptosis in corneal epithelium and lead the apoptosis in corneal stroma. The degree of apoptosis was recovered after lens removal, suggesting the process might to be reversible. The fitting with RGL induced apoptosis of keratocyte more than the fitting with RGP did. It suggests that the RGL wearing may be less physiologic than RGP wearing.

Journal of the Korean Neurological Association 1995;13(3):464-472
BACKGROUND AND PURPOSE: Arginine esterase(Ancrod), a thrombin-like enzyme, purified from the venoms of Agkistrodon halys, has known to cleave fibrinopeptide A from the fibrinogen and lead to circulation of soluble noncross-linked "ancrodfibrin', which stimulates endogenous T-PA release.Many authors have suggested clinical applicability of this enzyme,but clinical studies on its fibrinolytic action has been insufficient.Thus we studied the influence of this enzyme on fibrinolytic activity in cerebral infarction. METHOD: We observed the change of euglobulin fibrinolytic activity, t-PA antigen, t-PA activity, fibrinopeptide A, fibrinogen, FDP and D-dimer, during 12 hours after a bolus intravenous administration of 0.25 unit of the arginine esterase to the 9 patients with cerebral infarction. RESULT:There was no change of the euglobulin fibrinolytic activity, fibrinopeptide A and t-PA Ag but there was significant increase in both t-PA activity and FDP, D-dimer and significant decrease in fibrinogen. CONCLUSION: Our result suggest that arginine esterase converts fibrinogen to a fibrin polymer which has a increased susceptibility to lysis by plasmirl This enzyme seems to amplify T-PA activity through the consequent increase in FT)P, because there is no increase in the euglobulin fibrinolytic activity, fibr'mopeptide A and t-PA Ag suggesting direct T-PA release. Arginine esterase, having action of effective defibrinogenation and safe fibrinolysis,could be used for the thrombus related disease.

The effect of Pheniramine(Avil), a histaminergic-1 receptor blocking agent presently employed in treating various allergic diseases on pressor actions of norepinephring(NE) and tyramine (TR) was studied in the rabbit. Pheniramine, when given into a femoral vein with a dose(3mg/kg) enough to block H1-receptor, potentiated markedly the pressor responses of NE and TR. The pressor action of NE augmented by pheniramine was not affected by additional adminstration of debrisoquin (Drenergic neuron blocker) or phenelzine(monoamine oxidase inhibitor) or desipramine(U1-uptake blocker), or while potentiated by additional treatment with chlorisondamine(ganglionic blocker)or reserpine(catecholamine depleter). The hypertensive response of NE to phenelzine or desipramine was reinforced significantly by addition of pheniramine, but the response of NE in rabbits treated with reserpine or chlorisondamine or debrisoquin was not influenced by pheniramine-addition. Elevation of blood pressure to TR potentiated by pheniramine was attenuated significantly by reserpine treatment with chlorisondamine made the significant augmentation of pressor action to TR after pheniramine. Tyramine-induced response of blood pressure after pheniramine, but the response of blood pressure to TR caused by phenelzine or desipramine was enhanced markedly by pheniramine-treatment. From the above experimental results, it is thought that the pressor effect of NE and TR potentiated by pheniramine is similar to that of debrisoquin, i.e. the sensitization of effector cell, and that central action of pheniramine can not ruled out.

Chronic granulomatous disease is characterized by recurrent life-threatening infections and the formation of granulomatous lesions caused by the failure of phagocytic oxidative microcidal activity that has resulted from a defect of the oxidase system. The fungal osteomyelitis of the spine in this disease is almost always caused by Aspergillus, and its treatment is not yet established although surgical management, antifungal agents, granulocyte transfusions or combination methods have been reported. We report a patient with aspergillosis who had a long-standing pulmonary lesion which subsequently spread to the adjacent thoracic wall and spine. After decompression and drainage by costotransversectomy, the severe pain was relieved but the kyphosis increased and a paraplegia developed slowly because of resistance to the antifungal therapy and the inability to perform a bone graft. The patient died 2 months after the operation because of pulmonary complications.
