The purpose of this study change of physical fitness to season training on tennis players, the subjects of this study are selected from university athletes of 10 players. the statisics empolved in the study was pair t-test singnificance level was p<.05. the conclusion through materials of analysis was as follows: 1. the body composition was not significantly between the pre season and post season. 2. the back muscle strength(p<.01) and grasping power(p<.01) was significantly increase on post seasion when compared with pre season. 3. the flexibility wassignificantly increase on post seasion when compared with pre season(p<.05).4. the agility was significantly increase on post seasion(47.1±2.9) when compared with pre season(42.6±4.0)(p<.05). 5. the whol body reactivity by sound and light was not significantly between the pre season and post season. thus, details training demand specific training and professional trainer for improvement of skill.

Department of Rehabilitation medicine, Seoul National University College of medicine,Seoul National University Boramae Hospital*Background: The purpose of this study was to investigate factors related to the functional outcome of stroke patients at discharge. Methods: Retrospective analysis of existing medical records of 202 stroke patients was performed. Checked variables were: 1) whether the patient was transferred to the rehabilitation unit or not, 2) functional outcome at discharge, 3) the length of hospital stay and rehabilitation course, 4) risk factors such as hypertension, heart disease, diabetes mellitus, and hypercholesterolemia, 5) department of admission, 6) dischar g e course. The factors associated with functional outcome at discharge were analyzed using multiple logistic regression analysis. Results: A multivariate analysis revealed that the following factors were found to be associated with good functional outcome at discharge: 1) ischemic stroke (OR=5.733, p=0.003), 2) transfer to the rehabilitation unit (OR=7.004, p=0.001 ). Factors such as risk factors, department of admission, discharge course, length of hospital stay and rehabilitation course showed no significant association with good functional outcome at discharge. Conclusions: Although there may be selection bias, whether the patient was transferred to the rehabilitation unit or not is the strongest prognostic factor for the functional outcome at discharge. Therefore, it seems important for the stroke patients be treated at the rehabilitation unit.

A 9 months intact male American bull dog with chief complaints of dry cough, dyspnea and fever was referred to the Veterinary Teaching Hospital, Chungnam National University. Based on the findings of physical examination, radiological examination, and blood and blood chemical examinations, the present patient was diagnosed into pulmonary edema secondary to primary bacterial and aspiration pneumonia. The patient was hospitalized and treated with buscopan, cephazolin and furosemide for 1 week. His activity and appetite was returned to normal and thoracic radiographs revealed that Jung was recovered to the normal condition after treatment for 7 days. The present patient was a case with pulmonary edema showed favorable therapeutic responses to proper medication.

Targeted radionuclide therapy (TRT) is a method of treating tumor cells using radiopharmaceuticals. Cells and nuclei constituting tissues of the human body are composed of spherical and oval shapes, but cancer cells are composed of various cell types. Therefore, this study analyzed the absorbed dose for each organelle according to the change in the size of the cell nucleus for beta-emitting nuclides during targeted radionuclide therapy through the Monte Carlo method. Cells were set in two sphere shapes, 5 μm and 10 μm, and the internal structure was divided into cell nucleus, cytoplasm, and cell surface. Next, the absorbed dose according to the increase in the size of the cell nucleus was evaluated. As a result, 177Lu among the target radionuclides showed the highest dose in all cell compartments. As the ratio of the nucleus in the cell increased, the absorbed dose on the cell surface increased, but the absorbed dose in the cytoplasm and nucleus tended to decrease. Accordingly, it is judged that it is important to select a radionuclide considering the size of cancer cells and determine an appropriate amount of radioactivity during targeted radionuclide treatment. 표적 방사성핵종 치료(targeted radionuclide therapy, TRT)는 방사성의약품을 사용하여 종양세포를 치료하는 방법이다. 인체의 조직을 구성하는 세포와 핵은 구형과 타원형으로 구성되어 있지만, 암세포의 경우 다양한 형태의 세포 형태로 이루어져 있다. 이에 본 연구는 몬테카를로 방법을 통해 표적 방사성핵종 치료 시 사용되는 베타선 방출 핵종을 대상으로 단일 세포 내 세포핵의 크기 변화에 따른 세포 구성 영역별 흡수선량을 분석하였다. 세포는 5 μm, 10 μm 두 가지의 크기의 구 형태로 선정하였으며, 세포의 내부 구성은 세포핵, 세포질, 세포 표면으로 구분하였으며, 세포핵의 크기 증가에 따른 흡수선량을 평가하였다. 그 결과, 표적 방사성핵종 중 177Lu이 세포 모든 구획에서 가장 높은 선량을 나타냈으며, 세포 내 핵의 비중이 증가함에 따라 세포 표면의 흡수선량은 증가되었으나, 세포질과 세포핵의 흡수선량은 감소하는 경향을 보였다. 따라서 표적 방사성핵종 치료 시 암세포의 크기를 고려한 방사성핵종의 선택과 적절한 방사능량 결정이 중요할 것으로 판단된다.
