2.A Study on Correlation between Occlusion and Reperfusion Arrhythmias in the Cats.
Korean Circulation Journal 1990;20(1):108-120
Recently it has been stated that animals without ischemic arrhythmia would be at almost no risk for reperfusion ventricular fibrillation(VF) in contrast to animals with ischemic arrhythmias. In order to observe the differences of ararrhythmias characteristics between ischemic and reperfusion period, and correlationship between occlusion and reperfusion arrhythmias, the left anterior descending(LAD) coronary artery was occluded for 20 minutes and reperfused for 10 minutes in 24 anesthetized cats. The results were as follows; 1) After ligation of LAD coronary artery, the R wave, S-T segment and T wave of epicardial EKG were elevated to reach maximum level at 5-10 minutes. 2) During reperfusion, the changes of R wave, S-T segment, and T wave of epicardial EKG were not significant. 3) The incidence of arrhythmias at early phase and late phase of occlusion period were 41.6% and 100% respectively. The ischemic arrhythmia score was 2.38+/-1.61 and incidence of ventricular tachycardia(VT) was 66% 4) The incidence of VT and VF during reperfusion was 100% and 62.5% respectively. The reperfusion arrhythmia score was 5.88+/-1.72. 5) The two morphologies of ventricular arrhythmias were observed at occluson and reperfusion period. 6) The disparities between occlusion and reperfusion arrhythmias were observed. 7) The cats with shorter R-R internal and/or lower systolic left ventricualr pressure had the higher incidence of VF. In summary, although the morphology of occlusion ventricular arrhythmias was similar to that of reperfusion ventricular arrhythmias, the lack of correlation between reperfusion VF and ischemic arrhythmias was observed. So we suggest that further studies which provide the different mechanisms involved in occlusion and reperfusion arrhythmias were needed.

5.Juvenile DErmatitis Herpetiformis : Bullous Type: Report of a Case.
Korean Journal of Dermatology 1974;12(3):171-173
Dermatitis Herpetiformis rarely in childhood, and certain features of the disease in children differ from its manifestations in adults. Juvenile dermatitis herpetiformis appears not to be the same disease as the typical dermatitis herpetiformis of adults. Juvenile dermatitis herpetiformis has been described as a predomimantly bullous disease, but rarely papulovesicular eruptions. This bullous eruption in children must be considered in the several entities such as bullous pemphigoid and erythema multiforme. Juvenile bullous dermatitis herpetiformis has not responded routinely to sulfapyridine and sulfone therapy. A 15-month-old child whose skin lesions fulfilled clinical, histologic, and therapeutic criteria for Juvenile dermatitis hepetiformis is reported. The skin lesions showed bullous eruptions and also complained of severe itching sensation different from bullous Juvenile dermatitis herpetiformis.

8.Comparison of Cinical Results between the Anterior Interbody Fusion and the Posterolateral Fusion with Transpedicular Fixation for the Treatment of Isthmic Spodylolisthesis in Adults.
The Journal of the Korean Orthopaedic Association 1997;32(1):16-29
The results of surgical treatment for isthmic spondylolisthesis in children and adolescent have been well documented. Successful clinical results with fusion can be expected in children and adolescent. But in adults, instability was not the only problem. In addition to their instability, adults were more likely to have degenerative disc changes and nerve compression not solved by fusion only. The role of decompression in the surgical treatment of adult isthmic spondylolisthesis remains controversial. Anterior interbody fusion could obtain indirect decompression of nerve root through widening of intervertebral space. Posterolateral fusion with transpedicular fixation could get direct decompression. So, the purpose of this study is to compare the clinical results of the anterior interbody fusion and the posterolateral fusion with transpedicular fixation for the treatment of isthmic spondylolisthesis in adults. We reviewed the clinical data of 40 adult patients who had been taken operation due to isthmic spondylolisthesis from June, 1977 to June, 1994. The anterior interbody fusion was performed in 20 patients (Group I) and the posterolateral fusion with transpedicular fixation was performed in 20 patients (Group II). The mean age of group I was 44.1 years old (21-62), and that of group II was 41.3 years old (21-57). The gender of patients was 8 males and 12 females in group I, and 5 males and 15 females in group II. The symptoms and signs of group I and II were similar. The duration of follow-up was average 3.6 years (1.1-16 years) in group I and average 2.3 years (1.1-6 years) in group II. The anterior slippage of group I by Taillard method was 16.1% and was corrected into 10.4% after opera-up was average 3.6 years (1.1-16 years) in group I and average 2.3 years (1.1-6 years) in group II. The anterior slippage of group I by Taillard method was 16.1% and was corrected into 10.4% after operation. That of group II was 15.2% and corrected into 9.8% after operation. The fusion rate at 12 months after operation was 90% in group I and 95% in group II. The clinical results were analysed by Kim's criteria that was focused on the improvement of clinical symptoms. The satisfactory results were obtainted in 85 % of group I and 90 % of group II. So there was no significant difference of clinical results between the anterior interbody fusion and the posterolateral fusion with transpedicular fixation for the treatment of isthmic spondylolisthesis in adults (p<0.05).

9.Three Cases of Typical Clinical Characteristics and Overview of Neuroleptic Malignant Syndrome.
Journal of the Korean Society of Biological Psychiatry 1997;4(1):136-145
We are report on three cases of typical clinical characterstics and treatment response in neuroleptic maligant syndrome(NMS), and reviewed the literatures of NMS. NMS was first recognized as a life-threatening complication of dopamine receptor antagonists, and defined as a catatonic-like states associated with fever, obtundation, muscle rigidity, and unstable vital sign in patients taking neuroleptic agents. Concepts of NMS have changed because medications other than classic neuroleptic drugs have been implicated as triggering agents and syndromes identical to NMS have been observed in other conditions. The important neurochemical features are probably functional dopamine deficiency and ensuing hyperactivity of excitatory amino and neurotransmission in the basal ganglia and hypothalamus. Recognition of NMS and early discontinuation of neuroleptics are the most important step in its management. Supportive care includes management of hyperthermia and fluid replacement. Contraversial therapeutic measures include the application of dopamine receptor agonists, excitatory amino acid antagosists, or dantrolene. Psychiatric patients with a history on NMS and psychotic relapse necessitating antipsycotics do not commonly redevelop NMS.

Morphological characteristics of human embryos of Carnegie stage 17 were described. The crown rump length of these embryos were 11.7-13.6mm. These embryos were characterized externally by ventrally directed nasal pits, 6 distinct auricular hillocks, finger rays in the hand plate, digital plate at the lower limb bud, herniation of a part of midgut through umbilical cord, and internally by the partial fusion of ventral and dorsal pancreas, prominent nasal sac which is not open to primitive oral cavity, formation of segmental and some subsegmental bronchial buds, branching of metanephrotic pelvis, crescent-shaped lens cavity, and imminent semicircular ducts.
