The purpose of the present study was to investigate the effects of familiar exercise and novel exercise on motor function after intracerebral hemorrhage (ICH) in rats. The rats were subjected to a unilateral striatal ICH via collagenase infusion. The rats were randomly divided into the following three groups: the CON (control group; rested one week post-ICH), the FE (familiar exercise group; familiar exercise was performed two weeks after one-week post-ICH period), and NE (novel exercise group; novel exercise was performed two weeks after one-week post-ICH period). We measured neurological behavior using a ladder rung walking test and a beam walking test; we measured the level of nerve growth factor (NGF) using immunohistochemistry and western blot analysis. We performed a one-way ANOVA test to analyze the scores obtained from the neurological behavior tests and the differences of NGF protein levels among the three groups. In the present study, the FE group and the NE group showed significant improvement during the neurological behavior tests and in their expression of NGF protein level, as compared to the CON group. Especially, NE group more increase than FE group in neurological behavior tests, the expression of NGF on motor cortex. In conclusion, these results suggest that, after ICH, familiar exercise and novel exercise enhance motor function and, novel exercise is more effective than familiar exercise.

The purpose of this study is to examine the effect of transfer of training approach on cognitive function and functional recovery and the difference in the stroke patterns of adult stroke patients with affected cognitive function. Twenty stroke patients were participated ; 8 males and 12 females, the age ranged from 34 to 73. By the classification of diagnosis, 10 subjects were cerebral infarction and 10 subjects were cerebral hemorrhage, by the classification of affected side, 11 Rt hemiplegic patients, 9 Lt hemiplegic patients who were above at least post onset 2 month to a year. It was evaluated and analyzed pre and post treatment with MMSE and FIM, and the method of transfer of training approach was practiced every 30 min a day for a month. The data were analyzed by t-test and one way ANOVA. The results of this study were as follows: 1. There was significant in the effect of transfer of training approach on cognitive function of stroke patinets. 2. There was significant in the effect of transfer of training approach on functional recovery of stroke patients. 3. There was a significant difference in the effect of treatment in the group of cerebral infarction.

본 연구에서 제안된 질감특징분석 알고리즘은 뇌출혈환자의 CT영상을 이용하여 정상영상과 질환영상으로 구분하여, 고유영상 및 실험영상을 생성하고 제안된 컴퓨터보조진단 시스템에 적용하여 6개의 파라메타로 정량적 분석을 통해 뇌출혈 CT영상의 인식률을 도출하고 평가하였다. 결과로 뇌출혈 CT영상 40증례 중에서 각각의 질감 특징값에 대한 인식률은 평균밝기의 경우 100%, 평균대조도의 경우 100%, 평탄도의 경우 100%, 왜곡도의 경우 100%로 높게 나타났고, 균일도의 경우 95%, 엔트로피의 경우 87.5%로 다소 낮은 질환 인식률을 보였다. 따라서 본 연구의 결과를 바탕으로 의료영상의 컴퓨터보조진단 시스템으로 발전된 프로그램을 구현한다면 뇌출혈 CT영상의 질환부위 자동검출 및 정량적 진단이 가능해 컴퓨터보조진단 자료로서 활용이 가능할 것으로 판단되며 최종판독에서 정확성과 판독시간 단축에 유용하게 사용 될 것으로 사료된다.
