Purpose: This is a retrospective study that investigated cancer patients' complaints of moderate or severe pain to analyze pain characteristics, pain relief interventions and their effects. Methods: The participants of this study were 363 patients who were hospitalized in the cancer ward for three to 30 days and scored 4 points or higher on the pain severity assessment. Results: The most frequent region of pain was the abdomen. The most frequent factor that exacerbated pain was movement. The most frequent pain alleviating factor was administration of analgesics. The most frequent pain type was breakthrough pain, and the most frequent non-pharmaceutical intervention for pain control was heat therapy. Among all, analgesics were routinely prescribed for 52.2% of the participants. Morphine sulfate was the most frequently used analgesic while Gabapentin was the most frequently used non-narcotic analgesic. At the time of discharge, 82.5% of the participants marked their pain intensity as 3 points or lower. Conclusion: For cancer patients complaining of moderate or severe pain, it is important to actively control pain from the beginning of admission. Thus, it is necessary to educate not only cancer patients using narcotic analgesic for pain control and their families but nurses about the effects and side-effects of drugs. Moreover, patients and their families need to learn how to assess and record pain at home to collect data that can be referred for future treatment.

Radiation therapy was the treatment of choice for CML in the past, in the form of SI or radioactive phosphorus. Its use has been replaced to a large extent by various chemotherapeutic agents. Recently SI in CML has been used, both to relieve painful splenomegaly and to take advantage of an indirect effect of SI on unirradiated bone marrow. We have treated 15 CML cases who had a huge spleen during chemotherapy or even after chemotherapy by 6 MV linear accelerator during the past two years at the Division of Radiation Therapy, Kang Nam St. Mary's Hospital, Catholic College. Response to SI has been rated according to the scoring system of Roger W. Byhardt, et al. which evaluated the splenic and hematologic response as well as the response of disease-related systems. According to this scoring system, most patients demonstrated a significant relief of splenomegaly along with improvement of hemogram. And we observed the change of Karnofsky Performance Status after SI, and survival after a confirmative diagnosis and SI.

Trigeminal neuralgia is defined "a sudden, usually unilateral, severe, brief, stabbing, recurrent pain in the distribution of one or more branches of the fifth cranial nerve". The initial treatment of choice for trigeminal neuralgia is medical therapy. In patients with medically intractable pain or intolerable medication side effects, invasive therapeutic approaches are often necessary. Based on the amount of evidence and estimated efficacy, carbamazepine is the drug of choice in the management of trigeminal neuralgia. In case of insufficient or no response to carbamazepine, second-line drugs can be added. In this study, the author tried to review and analyzed the cases of 90 patients whom had visited for treatment of trigeminal neuralgia at the Department of Oral Medicine, Kyungpook National University Hospital from 2003 to 2008. The results were as follows: 1. Trigeminal neuralgia was significantly more common with advancing age, and nearly twice as common in women than men (ratio of 2.1:1) 2. The maxillary branch of the trigeminal nerve involved most often (51.1%), and the right side of the face is affected more commonly than the left (ratio of 2.9:1). 3. 85(94.4%) patients had experiences visiting medical or dental specialties before being referred to the Department of Oral Medicine. 4. 40(44.4%) patients with trigeminal neuralgia had systemic diseases. 5. Treatment with carbamazepine monotherapy was satisfactory initially in 69(76.7%) the patients, and the mean daily dose of carbamazepine was 402.9mg. On the other hand, 16(17.8%) patients expressed effectiveness after combination therapy of carbamazepine and other drugs. 6. Of the 69 patients who had a good initial response to carbamazepine monotherapy, 18 patients became resistant, so that combination therapy of carbamazepine and other drugs were necessary. 7. 54(60%) patients developed side effects such as dizziness, drowsiness, nausea, vomiting, blood dyscrasias, skin rash and constipation, and 11 of the patients decided to stop tmedicaion due to side effects.

잠재적으로 항감염 약제로 사용될 가능성이 있는 약제들의 초기 연구과정에서 주된 관심사는 이들이 미생물(세균, 바이러스, 기타 기생충)에 대한 작용들이 있는가 하는 점이다. 이러한 작용들이 실험적으로 충분히 연구가 된 후에야 실험동물에서 그 효과를 연구한다. 항 바이러스 제제의 경우에는 세포배양을 통한 연구가 그 약제의 독성과 효용성을 나타내는데 필수적인 것이 된다. 여러 종류의 동물을 이용한 생체실험에서 약제의 일반적인 흡수와 배설, 분포 등에 관한 정보와 약제 자체와 동물 내에서의 대사적 변화에 대한 정보가 제공된다. 여러 가지 미생물로 감염을 시킨 적합한 동물과 여러 가지 용량으로 치료하는 실험을 통하여 약제의 항 감염 능력이 알려지게 된다. 동물에서의 생체실험과 실험관내에서 실험을 하고 나서야 사람에서의 연구가 이루어지게 된다. 소위 전임상시험에서 대표적 병원성 미생물에 대한 생물학적효과, 약리학적 효과와 독성 그리고 동물실험모델에서의 가능한 효과가 결정된 후에 임상시험에 들어가기 마련이다. 항균제의 임상시험에는 각각의 감염질환에 대한 진단 및 치료기준을 반영하는 것이 기본이다. 새로운 항균제의 임상시험에서는 안전성과 효과가 반드시 밝혀져야 한다. 1상에서는 인체에서의 약리효과, 안전성이 주목적이며, 2상과 3상은 겹쳐지는 점도 있으나 하나 또는 그 이상의 적응증에 대한 항균제의 효과와 단기간의 부작용은 2상에서 관찰하여야하며, 다수의 환자에서 제안된 적응질환의 무작위임상시험과 다수에서의 안전성도 3상에서 관찰하여야 한다. 4상에서는 이상에서의 자료로 시판된 후에도 계속해서 감시하는 것으로 지속적으로 안전성을 관찰하는 것이다. 이러한 기본사항외에도 소아, 임산부, 고령자등에서의 임상시험도 넓은 의미에서 포함되어야 할 것이며 또한 질적인 면에서 조절하는 Quality Assurance도 중요하다.양상은 세 용량군 간 차이가 없었으나, 시험기에서 발열의 발현율이 낮았으며, 발열일 수와 항생제 사용일 수가 짧았다. 결론: 골수억제 조절 효과는 용량에 따른 혈액소견에 미치는 영향, 부작용, 감염의 빈도, 감염발생에 따른 항생제 사용기간 등을 고려하여 그 임상 유효성 평가시, 제 3상 시험에 사용할 권장량 (recommended dose) 은 250 ug/$m^2$/d $\times$ 10d 으로 관찰되었다.5주에 부검한 랫드의 간에서 c-myc 종양단백의 발현은 모든 처리군들이 대조군에 비하여 높게 발현되는. 것이 관찰되었으나 시험개시후 26주에 부검한 랫드의 간에서 c-myc 종양단백의 발현은 대조군에 비하여 차이가 거의 없었다. 따라서 랫드에서 화학적으로 유도한 간암발생 과정에서 NK 세포활성이 현저하게 억제되는 것으로 생각되며, c-myc 종양단백의 발현은 시험개시후 15주에 그 발현이 확실한 것으로 사료되어 진다.에 영향을 주는 성분이 있음을 제시하였다.1과 항우울약들의 항혈소판작용은 PKC-기질인 41-43 kD와 20 kD의 인산화를 억제함에 기인되는 것으로 사료된다.다. 것으로 사료된다.다.바와 같이 MCl에서 작은 Dv 값을 갖는데, 이것은 CdCl$_{4}$$^{2-}$ 착이온을 형성하거나 ZnCl$_{4}$$^{2-}$ , ZnCl$_{3}$$^{-}$같은 이온과 MgCl$^{+}$, MgCl$_{2}$같은 이온종을 형성하기 때문인것 같다. 한편 어떠한 용리액에서던지 NH$_{4}$$^{+}$의 경우 Dv값이 제일 작았다. 바. 본 연구의 목적중의 하나인 인체유

Delirium is an organic psychiatric syndrome characterized by an acute onset, prominent disturbance of consciousness and cognitive impairment with fluctuating course. Although there is not a clear consensus concerning the optimal classification system for delirium subtypes, Lipowski(1983) firstly classified delirium by psychomotor activity, namely hyperactive, hypoactive, and mixed. According results of several following studies, prevalence of hypoactive delirium were not less than that of hyperactive delirium. But a diagnosis of hypoactive delirium often missed, which is most frequently misdiagnosed as depression and dementia. Hyperactive delirium can be caused by alcohol or benzodiazepine withdrawal, would be related with excessive dopamine and cholinergic deficiency, and is more responsive to high-potency antipsychotics therapy. Hypoactive delirium would be caused by metabolic encephalopathy, and tends to present a less responsiveness to antipsychotics and poorer overall prognosis with a prolonged duration of admission than hyperactive delirium. Delirium is not a homogenous syndrome. Because of different subtypes, it may have dissimilar underlying pathogenetic pathways. So different treatment strategies between various subtypes may be needed.

A 2-month-old intact male Pitbull terrier (weighing 1.01 kg) were referred with primary complaints of severe abdominal distension, exercise intolerance, retarded growth, yellow nasal discharge and anorexia. Diagnostic imaging studies found enlarged right atrium partitioned by abnormal membrane, severe pulmonic systolic jets (5.66 m/s of peak velocity) and right-to-left blood shunt at the inter-atrial septum. Based on clinical and diagnostic findings, the case was diagnosed as cor triatriatum dexter complicated with severe pulmonic stenosis and right-to-left shunted patent foramen ovale. Either surgical or interventional therapy has not been attempted, because of unstable patient's condition. Using blood transfusion, oxygen supply and cardiac medications (i.e., sildenafil, spironolactone, enalapril), the dog was recovered.

Purpose : To assess the prevalence and characteristics of headache comorbidity with epilepsy in children and adolescents in a specialty epilepsy clinic. Methods : Two hundred twenty nine consecutive patients attending the Chosun University Hospital Pediatric Epilepsy Clinic (mean age $10.0{\pm}4.1\;years$, range 4-17, M:F ratio 1.1:1.0) were interviewed with a standardized headache questionnaire. Headache was classified according to the International Classification of Headache Disorders, 2nd Edition and epilepsy was classified according to the International League Against Epilepsy. Disability was assessed using pediatric migraine disability assessment (PedMIDAS). Results : Of the 229 epilepsy patients, 86 (37.6%) had co-morbid headache. Of the headache patients, 64 (74.4%) had migraine (65.6%- migraine without aura, 20.3% - migraine with aura, 14.1% - probable migraine). The mean headache frequency was $7.2{\pm}8.4$ per month, mean duration was $2.2{\pm}4.0$ hours, mean severity was $5.2{\pm}2.2$ out of 10, and mean PedMIDAS score was $13.0{\pm}35.4$. The proportion of females was not higher in epilepsy with headache patients (48.8%) compared to epilepsy patients alone (48.0%). In the patients with migraine, 48.4% had complex partial seizures, 17.2% had simple partial seizures, and 34.4% had generalized seizures (P=0.368). A postictal association of migraine was reported in 18.8% with 17.2% reporting a preictal headache, and 7.8% reporting an ictal headache. Conclusion : The prevalence of headache in pediatric epilepsy is higher than that in general pediatric population, suggesting a co-morbidity of headache in epilepsy patients with migraine being the most frequent headache disorder. Altered cerebral excitability resulting in an increased occurrence of spreading depression may explain the headache comorbidity with epilepsy. Further studies are needed to assess the etiology of this co-morbidity as well as assess the frequency, duration, severity and disability response to antiepileptic drugs.

Objectives : When a patient who attempts suicide visits the emergency room, it is important that the departments of emergency medicine, internal medicine, and psychiatry communicate with each other and prioritize treatment. This study was conducted to verify the effectiveness of the multidisciplinary emergency consultation system (ECS) for drug intoxicated patients. Methods : We retrospectively analyzed the data from medical records prior to the ECS, from July 2017 to May 2018, and after the ECS, from July 2018 to May 2019, to verify the effectiveness of the system. Results : After the ECS, admission to open wards was significantly higher than to the intensive care units (χ²=8.567, p=0.014). In addition, the proportion of consultations to the department of psychiatry among patients admitted to other departments tended to increase (χ²=4.202, p=0.053), and the time required for consultation response decreased (Z=-2.031, p=0.042). As a result of the consultation, the proportion of the patients who had been transferred to the department of psychiatry was increased (χ²=4.692, p=0.043), and the time spent to transfer tended to decrease (Z=-1.941, p=0.052). Conclusions : After implementing the ECS for drug intoxicated patients, unnecessary intensive care unit admissions, consultation response time, and the time spent to transfer were reduced, and the rate of consultation referrals and transfer rates increased. This means that the multidisciplinary consultation system rapidly provided essential medical services to patients at lower medical costs.

The initial burst of drug release is an important role in the controlled delivery of drug having hish toxicity and narrow therapeutic ranges. Nanosphere composed of monolayer could not achieve precisely controlled drug release because of the initial burst of drug on surface. In this study, double layered nanosphere was prepared for sustained drug delivery without initial burst. Double layered nanosphere composed of dextran and PLGA was fabricated by using conventional W/O/W double emulsion method. To control surface tension on the outer layer of nanospheres, PVA was used as a surfactant. Release behavior of dextran as model drug was observed as the $3{\times}1$mm wafers formed by compression mould in the deionized water for 7 days. Double layered nanosphere has sustained release behavior, in contast to single layered nanospheres. such as mechanical mixture and dextran nanospheres. Especially, nanosphere containing PVA $0.2\%$ has shown nearly the zero-order release profile. As a result of this study, double layered nanospheres has more sustained release profile of drug without the initial burst and the release behavior of dexoan on tile double layered nanospheres was controlled by the contents of PVA as a surfactant.

Objective : This study was a open clinical trial aimed at exploring the effectiveness of combined treatment with estrogen and antipsychotics to the chronic female schizophrenics. Method : 40 female patients who met DSM-VI criteria for schizophrenia who were chronically ill were randomly assigned to estrogen group(EG) and control group(CG). EG patients were received estrogen 1.25mg for 8weeks in addition to their routine antipsychotic regimens. CG patients were received their routine antipsychotic regimens only. Both groups were evaluated by PANSS(Postive and Negative Syndrome Scale), CGI(Clinical Global Impression) at 0, 4, 8 week during the trial period and compaired with each other. Results : 40 female patients have completed the study during 8weeks. EG was significantly improved in PANSS and CGI scores than CG during the 8weeks. In EG patients, all symptom subtypes(positive symptoms, negative symptoms, general psychopathology symptoms) of PANSS were significantly improved and positive symptoms were most significantly improved at 8week. Conclusions : This results support the clinical value of combined estrogen therapy among chronic female schizophrenics.
