Since cortison was administered to various clinical conditions, a large number of reports reviewed the influence of its application on the repair process of connective tissue. The effect of cortisone was described as consisting of delayed formation of fibroblast, rnucopolysac-charide and collagen, depressed activity of vitamin D in the human body, disturbed calciurn metabolism and consequently the delayed healing of the fracture. And it was therefore decided to investigate the effect of cortisone on fracture healing process. Twenty male rabbits weighing between 1500 and 2000 gms were used for this experiment. Their ribs were fratured and they were divided in 4 groups as follows: 1st group: control group 2nd group: vitamin. C 15mg/Kg. daily I. M. 3rd group: cortione acetate 20mg/Kg. daily I. M. 4th group: cortisone acetate 20mg/Kg. with vitamin. C 15mg/Kg. daily I, M. Gross and histological changes of healing process of ribs were observed, and results confirmed the delaying effect of cortisone administration in the fracture healing, on the contrary, the vitamin. C administration seemed to accelerate.

A 38-year-old male patient visited our clinic complaining of three skin lesions on the scalp. There were yellowish to brownish, waxy, non-tender, walnut-sized nodules. Hematoxylin and eosin staining revealed amorphous pinkish material deposits in the dermis. The Congo red stain and Dylon stain under polarizing microscopy showed yellow-green birefringence and the immunoglobulin-lambda light chain stain showed a positive reaction. An electron microscopic examination revealed filaments with uniform diameter(6 to 10nm) that were straight and neither branched nor anastomosed. Based on the clinical, histopathological, immunohistochemical and electron microscopical findings, the skin lesions were diagnosed as nodular amyloidosis.

Sepsis refers to the systemic response to serious infection. Patients with sepsis usually manifest fever, tachycardia, tachypnea, leukocytosis, and a localized site of infection. Methicillin-resistant Staphylococcus aureus(MRSA) is a gram-positive, nonmotile, aerobic, catalase- positive coccus, which is resistant to all the B -lactam antibiotics. Cutaneous manifestations in sepsis are maculopapules, nodules, petechiae, ecchymoses, purpurae, pustules, vesiculobullae, hemorrhagic bullae and ulcers. When MRSA is identified in blood cultures and skin tissue cultures, the skin lesions can be considered as cutaneous manifestations in sepsis caused by MRSA. We report two cases with erythematous pustules, petechiae, hemorrhagic bullae and maculopapules caused by MRSA sepsis. MRSA grew in blood cultures and skin tissue cultures.

Synovial chondromatosis is a condition of metaplastic and focal formation of cartillage in the intimal layer of synovial membrane. The etiology is unknown. The cartilagenous foci become pedunculated and may be sequestrated into the synovial cavity to form loose body. The center of focus may calcify and ossify. Of the ten cases of synovial chondromatosis experiences by the authors, five cases invo1ved the knee joint, one case both knee joint, two cases the hip joint, two cases the elbow joint, one case the wrist joint. The diagnosis of synovial chondromatosis was made by the histopathological finding of the excised masses.

Lamotrigine is an antiepileptic drug widely used to treat epileptic seizures. Using whole-cell voltage clamp recordings in combination with a fast drug application approach, we investigated the effects of lamotrigine on 5-hydroxytryptamine (5-HT)₃ receptors in NCB-20 neuroblastoma cells. Co-application of lamotrigine (1~300 µM) resulted in a concentration-dependent reduction in peak amplitude of currents induced by 3 µM of 5-HT for an IC₅₀ value of 28.2±3.6 µM with a Hill coefficient of 1.2±0.1. These peak amplitude decreases were accompanied by the rise slope reduction. In addition, 5-HT₃-mediated currents evoked by 1 mM dopamine, a partial 5-HT₃ receptor agonist, were inhibited by lamotrigine co-application. The EC₅₀ of 5-HT for 5-HT₃ receptor currents were shifted to the right by co-application of lamotrigine without a significant change of maximal effect. Currents activated by 5-HT and lamotrigine co-application in the presence of 1 min pretreatment of lamotrigine were similar to those activated by 5-HT and lamotrigine co-application alone. Moreover, subsequent application of lamotrigine in the presence of 5-HT and 5-hydroxyindole, known to attenuate 5-HT₃ receptor desensitization, inhibited 5-HT₃ receptor currents in a concentration-dependent manner. The deactivation of 5-HT₃ receptor was delayed by washing with an external solution containing lamotrigine. Lamotrigine accelerated the desensitization process of 5-HT₃ receptors. There was no voltage-dependency in the inhibitory effects of lamotrigine on the 5-HT3 receptor currents. These results indicate that lamotrigine inhibits 5-HT₃-activated currents in a competitive manner by binding to the open state of the channels and blocking channel activation or accelerating receptor desensitization.

Interest in the prevalence of patent foramen ovale(PFO) and its relation to embolic stroke has increased with the sophistication of methods for noninvasive cardiac assessment. The effect of foramen ovale closure on the risk for subsequent strokes is promised. A 22-year old woman was presented with sudden onset of cerebral infarct. She had a patent formen ovale, and right to left shunt during the Valsalva maneuver, which was diagnosed by transesophageal contrast echocardiography. Transcatheter closure of PFO was performed with Rashkind PDA umbrella under the guidance of transesophageal echocardiography. Transcatheter closure of PFO can be accomplised with little morbidity and may reduce the risk of embolic episode.

BACKGROUND: Systemic anticoagulation therapy has been recommended to prevent subacute thrombosis after intracoronary stening. Recent data, however, suggest that antiplatelet therapy might be an effective alternative to anticoagulation therapy. We evaluated the effect of antithrombotic regimens on subacute thrombosis and short-term clinical course after successful implantation of Cordis coronary stent, which is a flexible, balloon expandable, radiopaque tantalum stent. METHOD: Two hundred and seventy-five consecutive patients with 290 lesions were treated with 356 Cordis stents implantation. According to post-stent antithrombotic regimen, patients were divided into three groups ; 165 patients with 175 lesions received aspirin 200mg/day, ticlopidine 500mg/day and warfarin for one month(Group 1), 66 patients with 69 lesions received aspirin and ticlopidine(Group 2) and 44 patients with 46 lesions received aspirin alone(Group 3) after successful Cordis stenting. RESULTS: The overall procidural success rates were 97.7% in group 1, 98.6% in group 2 and 100% in group 3. More than 65 percents of the patients were eligible for elective stenting aspirin, ticlopidine and warfarin, 0% in patients with aspirin and ticlopidine, and 6.8% in patients assigned to the treatment with aspirin alone. CONCLUSION: The Cordis coronary stent is an effective endovascular stent in various clinical indications including unstable angina and acute myocardial infarction. Antiplatelet therapy using aspirin and ticlopidine after successful Cordis coronary stenting is promising alternative to anticoagulation therapy to overcome the drawbacks of stenting. However, post-stent antithrombotic therapy with aspirin alone is associated with significant rate of stent thrombosis.

Subcutaneous granuloma pyogenicum (SGP) is a rare variant of granuloma pyogenicum. In general, it appears as a single subcutaneous nodule with a slight tenderness. We report herein an unusual case of SGP arising from the left palm of an 11-year-old girl. Two mild-tender bean-sized reddish or flesh colored subcutaneous nodules on the lateral border of the left palm, and medial side of 5th left finger, respectively, were noted on physical examination. Histopathologic examination revealed the findings of lobular capillary hemangioma, characterized by localized proliferation of capillary lined by a single endothelial cell layer. Intralesional injection of triamcinolone acetonide (TA) were performed for the treatment. However two new erythematous nodules developed at another area of the left palm, which disappeared without any treatment.

It is important to detect binocular suppression of pediatric strabismic patients, especially in accommodative esotropes and intermittent exotropes. However, it may take a long time and false results may be obtained in young children. In order to examine binocular suppression, we selected 103 accommodative esotropes with binocular suppression. Vectograph test, Worth 4 dot test, and 4 prism base-out test were performed at distance, and Worth 4 dot test, TNO test, and Bagolini test at near. Titmus fly test and Randot stereotest were administerd to know the relationship between stereoacuity and suppression. In detecting binocular suppression, the true rate of vectogram was 95%, which was the highest result of all tests and 4 prism base-out test was the next with 88% of the true rate. The stereoacuity was increased in proportional to the absence of suppression. The vectographic porject test was the easiest and the most accurate test to identify normal fusion or binocular suppression at distance in young strabismic children. The accuracy will be increased in the combination with 4 prism base-out test. Therefore the vectograph also can be used in the screening of small amount of deviation, monocular amblyopia and low vision in kindergarten and elementary school.
