Background The olive founder (Paralichthys olivaceus) is a saltwater fsh, which is valuable to the economy. The olive founder strives to adapt to environmental stressors through physiological, biochemical, and transcriptional responses. The rise in water temperature threatens the growth, development, reproduction, and survival of olive founder. Each organ in the olive founder can diferentially respond to heat stress. Objectives The purpose of this study is to investigate organ-specifc transcriptional changes in olive founder tissues during heat stress. Methods In this study, transcriptome dynamics of the gill, liver, and muscle of olive founder to acute or chronic heat stress were investigated. Results Principal component analysis plotting revealed that the transcriptome of each organ is quite separated. K-means clustering, gene ontology, and Kyoto Encyclopedia of Genes and Genomes pathway analysis showed the diferential transcriptome responses of each organ to heat stress. Heat stress commonly afects the pathways involved in the correct protein folding, DNA repair, and cell cycle. Conclusion Our results may provide a valuable molecular basis of heat acclimation in fshes.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

Many studies have been performing to attenuate hemodynamic responses in related to anesthesia of hypertensive patients because increased blood pressure and heart rate may be even fatal. The author performed this experimental study to evaluate the hemodynamic effect of labetalol which has dual site of action(non-specific beta and postsynaptic alpha 1 receptor blockade) and SNP on cardiovascular system under the 1 % isoflurane anesthesia in 14 mongrel dogs. Heart rate(HR), systolic arterial blood pressure(SAP); diastolic arterial blood pressure(DAP), mean arterial blood pressure(MAP), central venous pressure(CVP), pulmonary arterial pressure (PAP), pulmonary capillary wedge pressure(PCWP), and cardiac output(CO) were measured after labetalol 0.08mg/kg, 0.24mg/kg, and 0.72mg/kg intravenous bolus injection and SNP 0.7mg /kg/min, 2.1mg/kg/min, and 6.3mg/kg/min intravenous dripping. Besides stroke volume (SV), cardicac index(CI), left ventricular stroke work index(LVSWI), systemic vascular resistance (SVR) and pulmonary vascular resistance(PVR) were calculated. The results were summerized as follows 1. SAP, DAP and MAP were decreaed significantly in both groups. HR were decreased significantly in labetalol group but there was no change in SNP group. 2. PCWP showed a tendency to increase in labetalol group but to decrease in SNP group, PAP showed no change in both groups. 3. CO and CI were decreased significantly but SV was not changed in labetalol group. There were no changes in SNP group. LVSWI showed a tendency to decrease in both groups. 4. CVP, SVR and PVR were not changed in both groups. The author conclude both labetalol and SNP are effective to attenuate hemodynamic responses, in hypertensive patients. But labetalol is preferable for hypertensive patient with coronary heart. disease because it has dual blocking action.

Succlnycholine (1 mg/kg, 1.5 mg/kg) without pretreatment or succinylcholine (1 mg/kg, 1.5 mg/kg) with pretreatment by pancuronium (bolus 1 mg, 2 mg), and d-tubocurarine (3 mg, 6 mg bolus) were given to patients of relatively same physical status (ASA classification class Ⅰ, Ⅱ) at induction of general anesthesia to determine the degree of muscle fasciculation, vocal cord paralysis, onset and extnt of muscle pain in each group. The result are summarized as follows 1. Appearance of muscle fasciculation was significantly decreased with pretreatment of non-depolarizing muscle relaxant. (p<0.005) 2. The depressing effect of muscle fasciculation was relatively same in each dosage of non-depolarizing muscle relaxant, thus there is no statistic difference. 3. Degree of vocal cord paralysis was predominant in group of succinylcholine alone used. Degree of vocal cord palaysis was slightly decreased by pretreatment of non-depolarizing muscle relaxant, but comparision with control group, there is no statistic difference (p>0.05) 4. The reduced effect of vocal cord paralysis was relatively same in each dosage of non-depolarizing muscle relaxant, thus there is no statistical difference. (p>0.05) 5. Appearance of muscle pain was decreased by pretreatment of non-depolarizing muscle relaxant, especially pretreatment of pancuronium 2 mg bolus significantly decreased post-operative muscle pain. (When succinyline 1 mg/kg administration : 0.025<p<0.05, when succinylcholine 1.5 mg/kg administration: 0.01<p<0.025).

As an initial step for future genetic manipulations to improve forage characteristics of Italian ryegrass (Lolium multiflorum Lam.), an efficient tissue culture system was established and the factors affecting plant regeneration were evaluated. MS medium containing 5 ㎎/L 2,4-D was optimal for embryogenic callus induction from mature seed and had a strong effect on successive plant regeneration. The plant regeneration frequency was observed at above 70% when embryogenic calli induced were transferred to N6 medium supplemented with 1 ㎎/L 2,4-D and 5 ㎎/L BA. Among several basic media tested, MS and M6 medium were optimal for callus induction and plant regeneration, respectively. Genotype was an important factor in plant regenerability. 'Jeanne' showed the highest regeneration frequency of 73%. A short tissue culture period and high-frequency regeneration system established in this study will be useful for molecular breeding of Italian ryegrass through genetic transformation.

A competent velopharyngeal sphincter is essential for intelligible speech. If the velopharyngeal incompetence exist, the seal will not be complete during speech, with a resultant hypernasal speech quality. The patient with velopharyngeal incompetence(VPI) may develope other compensatory speech problems. There are many approaches available to correct veolpharyngeal incompetence, which include speech therapy, push back palatorrhaphy, pharyngeal wall implants and pharyngoplasty. This is cases report of velopharyngeal incompetence, which were successfully treated by superiorly based pharyngeal flap, covered with splitted hinge flap of nasal lining mucosa of the soft palate, named modified Hogan method. The advantages of this method are precision in the approximation of the flap due to pentagonal shaped flap design, good flood supply due to omission of the midsagittal incision on nasal lining mucosa, and simplicity than Hogan method.
