After administration of tetrabenazine (TBZ) 40 mg/kg), the pressor and cardioaccelerator responses of rabbits (whole anesthetized and spinal) to norepinephrine and tyramine were studied. The maxmal potentiation of the pressor activity of norepinephrine developed about 10 hours after TBZ administration. At this time the preesor response to tyramine was not decreased. The cardioaccelerator responses to both amines were not significantly altered. The TBZ-induced supersensitivity to norepinephrine was not increased by additional intravenous reserpine, but it was further increased by giving desipramine. Carbachol, given 2 and 6 hours after TBZ administration, inhibited the development of supersensitivity to norepinephrine by TBZ. The TBZ-induced supersensitivity was discussed in relation to reserpine-induced supersensitivity.

This study examined the effects of the occlusal stability and a partial coverage mouthguard on physical fitness and motor capacity to determine the importance of the occlusal stability as a possible action mechanism of mouthguards on physical performance. Twenty physical education students were included for measurements of their handgrip strength, back strength, whole body reaction time, flexibility, sidestep test, stork stand test and jumping test according to the following 5 different occlusal conditions: mouth closed position without a mouthguard, with a full coverage mouthguard, with a right partial coverage mouthguard, with a left partial coverage mouthguard and with anterior partial mouthguard. The results revealed no significant difference in any of the measured physical factors between the occlusal conditions with and without a full-coverage mouthguard. On the other hand, a significant difference was observed in whole body reaction between the occlusal conditions with and without the partial coverage mouthguards. Therefore, isokinetic muscle tests on both knee joints and the Wingate anaerobic power test should be performed under the following five occlusal conditions: with or without full-coverage maxillary custom-made mouthguard, with a unilateral right or left partial-coverage maxillary mouthguard and with an anterior partial-coverage maxillary mouthguard. These results suggest that the partial coverage mouthguard had a short-term beneficial effect on agility rather than full coverage mouthguard.

Background: Cardiopulmonary bypass is an essential process to maintain circulation for saving life during the cardiac surgery, But it is a process in which systemic inflammation was evoked inevitably because of the exposure of blood to foreign surface. The injuries to distal organs during the cardiopulmonary bypass were resulted from systemic inflammation and the disturbances of micro-circulations in the organs. We designed this study to research the effects of leukocyte depletion from pump-oxygenator priming solution on the systemic inflammation, and the micro-circulation of gastric mucosa that is suggested by the gastric mucosal $CO_{2}$ partial pressure and acidity. Material and Method: The dogs were divided into three groups according to the different pump-oxygenator priming solutions; non-hemic crystalloid solution; leukocyte-depleted homologous blood; and non leukocyte-depleted homo-logous blood. Each priming solution group contained five dogs. In all three groups, 2 hours of cardiopulmonary bypass, and 4 consecutive hours of general anesthesia was maintained on the mechanical ventilation. Each dog was evaluated for the gastric mucosal pH, $CO_{2}$ partial Pressure, arterial pH, $CO_{2}$ partial pressure, the exhaled air $CO_{2}$ partial pressure and the level of IL-8 on before the cardiopulmonary bypass, 1 hour after the cardiopulmonary bypass, 2 hours after the cardiopulmonary bypass, 2 hours after the restoration of normal circulation, and 4 hours after the restoration of normal circulation after the cardiopulmonary bypass. The levels of IL-8 were measured with ELISA (enzyme linked immunosorbent assay) technique. Result: 1. There were significant differences of gastric mucosal $CO_{2}$ partial pressure between the leukocyte-depleted homologous blood group and other two groups(vs non leukocyte-depleted homologous blood group; P=0.02, vs non-hemic crystalloid solution group; P=0,01). 2. The gastric mucosal pH of leukocyte-depleted homologous blood group was significantly different from non leukocyte-depleted homologous blood group (p=0.01). 3. The levels of IL-8, which examine the systemic inflammation, showed signi- ficantly better results in leukocyte-depleted homologous blood group and non-hemic crystalloid solution group than non leukocyte-depleted homologous blood group (p=0.01, 0.01). Conclusion: Based upon these results, we concluded that the leukocyte depletion from the pump-oxygenator priming solution has a beneficial effects in reducing systemic inflammation and the preserving of gastric mucosal micro-circulation.

Purpose : Immunotherapy is accepted as the only treatment of allergic disease that can modify the natural course of the disease and ameliorate symptoms. This study aimed to evaluate the safety and efficacy of ultra-rush therapy using Dermatophagoides extracts in children. Methods : Of children older than four years who had visited Bundang CHA Pediatric Allergy Clinic, those showing positive reactions only to Dermatophagoides in the skin prick test and to the nasal provocation test were included. In all, 11 and 12 patients respectively preferred conventional and ultra-rush immunotherapy. We elevated allergen concentrations diluted to 1,000:1 of the end strength by 2-3 times with 30-minute intervals and checked oxygen saturation, pulse rate, blood pressure, and systemic reactions every 15 minutes. Immunotherapy effectiveness was valued by changes in nasal provocation test scores before and after immunotherapy. Results : The average ages of patients in the conventional and ultra-rush immunotherapy groups were $8.3{\pm}2.3$ and $9.2{\pm}2.8years$, respectively. Systemic reactions were observed in six in the ultra-rush group (50%) without anaphylaxis and one (9%) in the conventional group. The average scores in the nasal provocation test before and after treatment in the conventional group were $8.2{\pm}1.5$ and $4.6{\pm}2.1$, respectively (P=0.043). In the ultra-rush immunotherapy group, the scores changed from $6.2{\pm}2.2$ to $3.7{\pm}2.5$ (P=0.017). Conclusion : Ultra-rush immunotherapy using Dermatophagoides in children is effective for treating allergic disease but can induce systemic effects rather than conventional immunotherapy.

Purpose: This study aimed to evaluate the immunogenicity and safety of a trivalent inactivated influenza vaccine (TIV) among healthy Korean children and adolescents. Methods: From October to December 2008, 65 healthy patients aged 6 months to 18 years who visited Korea University Ansan Hospital for influenza vaccination were enrolled in this study. We measured the hemagglutinin inhibition antibody titers at baseline and 30 days after vaccinating enrollees with split influenza vaccine and calculated the seroprotection rates, geometric mean titers, and seroconversion rates. Local and systemic adverse events were assessed after vaccination. Results: The seroprotection rates against all three viral strains (A/H1N1, A/H3N2, B) were 87.7%, 89.2%, and 89.2% (${\geq}70%$), respectively; seroconversion rates were 44.6%, 73.8%, and 63.1% (${\geq}40%$), respectively; and seroconversion factors were 4.5, 8.4, and 10.5 (>2.5), respectively. The TIV immunogenicity was acceptable according to the CPMP (Committee for Proprietary Medicinal Products) criteria. Although 48 patients (73.8%) reported one or more adverse events, no severe adverse events such as anaphylaxis and convulsion were observed. Forty-two patients (64.6%) reported a local skin reaction, including redness (29.2%), pain (43.1%), or swelling (41.5%) of the injected site, and 26 (40.0%) reported a systemic reaction: fatigue (23.1%), myalgia (20.0%), headache (10.8%), arthralgia (10.8%), chills (9.2%), or fever (7.7%). Conclusions: This study shows that the immunogenicity of the TIV vaccine is acceptable. As there were no serious adverse events aside from local reactions and mild systemic reactions, this vaccine can be safely used among healthy Korean children and adolescents.

본 연구에서는 생체 뇌 국소부위의 세포외액을 대상으로 실험할 수 있는 뇌 미세투석법을 이용하여 후시상하부에서 유리되는 monoamine의 세포외액 농도에 대한 전신 혈압변화의 영향을 관찰함으로써, 심혈관 조절에 대한 후시상하부의 monoamine성 뉴론의 생리적 역할을 규명하고자 하였다. 마취한 흰쥐의 머리를 뇌정위 고정장치에 고정시키고 미세투석관 (microdialysis probe)을 후시상하부에 위치시킨 후 링거액으로 관류하였다. 미세투석액내에 존재하는 monoamine성 신경 전달물질들과 그 대사체들의 정량분석은 고속액체크로마토그라피와 전기화학검출기를 이용하여 실시하였다. 전신 혈압을 40분 동안 약 40mmHg 상승 혹은 30mmHg 감소시키기 위하여 L-phenylephrine hydrochloride (800ng/100 g/min) 혹은 nitroprusside dihydrate (500 ng/100 g/min)를 대퇴정맥을 통하여 주사하였다. 후시상하부로 부터 20분 간격으로 얻은 투석액에서 신정화학물질들의 농도는 미세투석관 삽입후 2시간에 안정되었다. 관류액의 $K^{＋}$ 농도를 90 mM로 증가시켰을 때 후시상하부의 투석액에서 norepinephrine (NE) 과 serotonin (5-HT)의 농도는 각각 기준치의 176.5 $\pm$ 14.8%, 149.1 $\pm$ 2.3%로 증가하였다. Phenylephrine (i.v.)으로 유발된 전신 혈압상승에 의하여 NE과 5-HT의 양은 각각 기준치의 79.3 $\pm$ 4.4%, 61.4 $\pm$ 10.3%로 유의하게 감소하였다. 또한 nitroprusside (i.v.)에 의하여 전신혈압이 감소하였을 때 투석액내 5-HT의 양은 기준치의 195.0 $\pm$ 23.0% 로 유의하게 증가하였다. 후시상하부의 투석액내 monoamine성 대사체들의 경우에는 전신 혈압의 변화에 대한 유의한 반응을 나타내지 않았다. 이상을 종합하면 전신 혈압이 증가되었을 때는 말초 압수용체의 흥분에서 기시한 신경충동이 후시상하부에 전달되어 신경말단에서 5-HT 과 NE 의 유리가 감소되고, 5-HT의 경우에는 전신 혈압이 감소되었을때 그 반대 현상이 일어난다는 가설을 제시할 수 있다. 본 연구의 결과는 생체상태에서 혈압변화에 대한 후시상하부의 monoamine성 조절양상을 규명한 것으로서 특히 후시상하부의 serotonin성 신경계를 통한 심혈관 중추조절의 가능성을 처음으로 제시한 것이다.

Lymphoma is one of the most common malignant neoplasms of the dog. Little has been published on intraocular lymphoma in dogs. This report presents a 8-year-old neutered male mixed dog with a previous history on inflammatory debris on the anterior and posterior lens capsules, vitreal hemorrhage, generalized peri-pheral lymphadenopathy and a palpable mid-abodominal mass. History, clinical signs, radiography, cytology, histopathology and chemotherapeutic response confirmed multicentric lymphoma with secondary ocular infla-mmation. Intraocular lymphoma, the most common secondary neoplasm of the canine eye, may be the present-ing evidence of systemic disease. This report describes a dog that presented with ocular manifestations of multicentric lymphoma.
