1.Effect of decorin on tensile strength of healing flexor tendon.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2000;27(1):83-86
Adhesion formed between tendon and its sheath after repair often impairs functional recovery. There have been many attempts to reduce adhesion around a repaired tendon, but most results have been unsatisfactory or impractical in clinical application. Moreover, most attempts were focused on extrinsic tendon healing. whereas studies on the intrinsic tendon healing are sacrce in the literature. We have previously reported that fibrotic tendon adhesion after repair was decreased by decorin, a natural inhibitor of TGF-beta. Accordingly, the serial tensile strength was measured after complete tensection and repair of the tendon severance in order to confirm the effect of decorin inhibition of intrinsic healing capability. Forty White Leghorn chickens were subject to complete transection and repair of the third toe flexor digitorum profundus tendon in Zone II. In the experimental group, 0.5ml of diluted decorin(50microgram/ml) was injected around the repaired site, and the same volume of saline solution in the control group. Tendons were harvested at 1, 3, 5 and 7 weeks. The disrupting force of the repair site was analyzed using tensiometry(LLOYD LR 30K, U.K). The tensile strength of repaired tendon was similar in both groups for all postoperative periods. This indicates that intrinsic healing proceeds normally within the decorin group in spite of the blockade of TGF-betaactivity. Decorin, a natural inhibitor of TGF-beta, showed a significant inhibitory effect on reducing post-repair tendon adhesions, without disruption of intrinsic healing in the chicken flexor tendon injury model. Therefore, decorin is expected to be a useful agent for preventnion on tendon adhesion after the repair in clinical usage.

BACKGROUND AND OBJECTIVE: The clinical manifestation of Henoch-Schonlein purpura and existance of renal involvement may influence on its course and prognosis. To verify prevention with early administration of steroid, we studied the efficacy of corticosteroid treatment. MATERIAL AND METHOD: We analysed 65 children under 15 years of age with Henoch-Scho nlein purpura according to their age, sex, and seasonal incidence. Forty children showed typical skin lesions, arthralgia and abdominal pain. We have divided them two groups. Group A consisted of 20 children who received 1 mg/kg of prednisolone/perday for 2 weeks and group B did not. We carried out their physical examination and urinalysis monthly for a year. RESULT: The main clinical manifestations were skin rash(100% ), abdominal symptoms(41.5 %), joint symptoms (49.2%), and renal involvement(34%). As for gastrointestinal symptoms, abdominal pain(66.7% ) was most commonly observed one and others were nausea or vomiting (44.7%) and melena(25.9%). The joint involvement was observed mostly in knee(56.3%) and ankle joint(31.3% ), Hematuria was observed in all cases with renal involvement and proteinuria, in 28% of them. The improvement of renal manifestations were noted in 84.2% of them within 4 months. Mild elevation of IgA was more frequently observed in renal involvement group than non-involved group (p< 0.01). There were no significant differences in immonologic parameters such as IgG, IgM, IgE, duration of the acute phase and severity of cutaneous symptoms between two growps. None of steroid treated growp showed progression of nephropathy. Of the 20 non-steroid treated growp, 2(10%) developed nephropathy. Conclusion We may suggest that existance of renal involvement in Henoch-Schonlein purpura influences its course and prognosis.

BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

A rostro-caudal topography of the oculomotor nerve fascicles is relatively well known in animal but not in human. We experienced two cases of midbrain infarctions presenting with isolated oculomotor nerve palsies. The MRI of the patient who had monocular elevation palsy with ptosis revealed a lesion in the middle to lower midbrain, whereas that of the other who had monocular depression and adduction palsy with pupillary mydriasis showed a discrete lesion in the upper to middle midbrain. We present the rostro-caudal arrangement of the oculomotor fascicles within midbrain based on MRI findings.

A total of 33 patients with infective endocarditis were observed in the Guro and Hye Hwa Hospitals of Korea University Between September, 1981 and Feb, 1987. Among thses patients four patients presented with heart murmur and heart failure and had vegetation like findings observed on the two dimensional echocardiography. But these patients did not have any fever or leukocytosis in the peripheral blood and the repeated blood cultures were negative. They showed the immunologic phenomena of infective endocarditis such as microscopic hematuria in 4 patients, rheumatoid factor in 3 patients, false positive VDRL in one patient. The serum complement was decreased in 2 patients in whom it was checked. We report these 4 patients because we think these patients might be in the clinical stage in which the infecting organism is spontaneously cleared but the immunologic sequelae are remained.

We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

A 34-year-old female had an unusual case of cellular blue nevus which had behaved in a locally aggressive fashion. The lesion infiltrsted the adjacent soft tissue of left nail bed and extended into deep phalangeal bone. The involved left thumb was partially amputated because complete excision was impossible and we were quite concerned about malignant transformation. Histologically biphasic pattern without cellular atypism, a characteristic features of cellular blue nevus, was shown. About 2 years later, the lesion had not recurred.

The distribution of pemphigus subclass autoantibodies in a patient with pemphigus vulgaris (PV) has been investigated by semiquantitative indirect immunofluorescence (IIF), using the HP series monoclonal antibodies specific for four human IgG subclasses on human foreskins. IgG1 and IgG4 intercellular substance-specific autoantibodies were detected in the serum of the patient, whereas IgG2 and IgG3 autoantibodies were absent. In addition to foreskins, human tonsillar epithelia were used as substrates of IIF for detecting the PV autoantibodies and it was one of satisfactory substitutes for monkey esophagus.

10.Comparison Analysis of Two Different Training Methods for Cardiopulmonary Resuscitation by Laypersons.
Journal of the Korean Society of Emergency Medicine 2013;24(6):656-663
PURPOSE: This study compared the effectiveness and ease of operation of two different training methods, response sequence based training (RBST) and chest compression first training (CCFT), for cardiopulmonary resuscitation (CPR). METHODS: Eighty-five railroad workers were divided into two groups: those who applied the usual CPR training method (response sequence based training, 44 people) and those who applied our CPR training method (chest compression first training, 41 people). The objective skill performances were evaluated by using a mannequin (JAMY-IV RECO, Kyotokagaku, Japan). RESULTS: There was no statistical difference in CPR performance and artificial ventilation success rate between the RSBT group and the CCFT group. However, the artificial compression success rate and compression depth of the CCFT group compared to the RSBT group was statistically higher (p=0.006, 0.001). In addition, the wrong-hand-position rate of the RSBT group compared to the CCFT group was statistically higher (p=0.000). Furthermore, instructor satisfaction with practical training operations in the CCFT group compared to the RSBT group was statistically higher (p=0.001) and instructors reported that students were focused and easily capable of performing the CCFT training method. CONCLUSION: The chest compression first training method is easy to perform and not too complex to operate, making it effective in student performance and instruction. More effective CPR training is expected based on this method.
