1.Effect of Cortisone & Vitamin C on Experimental Fracuters in Rabbits
The Journal of the Korean Orthopaedic Association 1971;6(2):125-129
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.

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.

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.

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.

A nested polymerase chain reaction (PCR) was applied to detect and identify pathogenic Yersinia enterocolitica and Y. pseudotuberculosis. We used photochemical postamplification procedure with 8-methoxypsoralen to control carryover contamination. Using the ail and inv gene, the sensitivity and specificity of DNA amplification by nested PCR was considerably improved. The amplified fragment sizes were 298 bp for the ail gene and 295 bp for the inv gene. Amplification was successful when the template was derived from three sources: purified DNA, aliquots of boiled bacterial suspension and aliquots of lysed bacterial suspension. The detection limits were 10 fg of DNA and 2 * 10 colony forming units (CFU) for Y. enterocolitica and 10 fg DNA and 2 CFU for Y. pseudotuberculosis.

OBJECTIVES: Ginseng has a long history of being used in insomnia treatment and there is some evidence from animal studies of its sleep-enhancing property. From this, it can be assumed that ginseng has sleep-promoting effect in humans. The purpose of this study was to investigate the effect of Korean red ginseng on change of sleep architecture in humans. METHODS: A total of 20 healthy young males with regular sleep and wake habits and without any psychiatric nor cognitive problems were selected based on review of sleep questionnaires and sleep diaries they completed followed by an interview with a board-certified psychiatrist. The subjects were randomly assigned to red ginseng or placebo for 2 weeks of trial. The total daily dose of ginseng was 4,500 mg. The polysomnographic recordings were made at baseline and at 2 weeks after. The effects of red ginseng and placebo on sleep were assessed by comparing the changes in polysomnographic variables between the two groups. RESULTS: A total of 15 subjects, 8 from red ginseng group and 7 from placebo group, were included to undergo polysomnographic procedures. The red ginseng group showed tendencies to increase stage 3 sleep (p=0.087) and to decrease stage 2 sleep (p=0.071) from the baseline compared with the placebo group. CONCLUSION: Korean red ginseng tends to increase deep sleep and decrease shallow sleep. Our result is in line, at least in part, with previous findings that Korean red ginseng increased total and NREM sleep in rats. Further studies with higher ginseng dosage, larger sample size and longer trial duration should be conducted to confirm the sleep stabilizing and balancing effects of Korean red ginseng.

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.

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.
