어류는 생존과 번식을 위해 회유 또는 이동을 하며, 이러한 회유나 이동은 어종에 따라 넓은 범위에서 이루어 질수도 있고 국지적으로 이루어 질 수도 있다. 피라미는 한국의 강과 하천에 우점종으로 서식하는 어종이다. 그러나 하천에 설치된 댐, 보, 암거 등은 어류가 이동하거나 번식하는데 많은 장애가 되고 있다. 실제로 어류 서식처간의 연결부가 배수암거(culvert)로 설치되어 있는 경우에는 평상시 피라미와 같이 몸집이 작은 어류가 이동하는데 장애를 줄 정도의 빠른 유속과 낮은 수심이 발생되고 있다. 그러나 국내에서는 국내 하천에 서식하고 있는 민물고기의 유영특성에 관한 연구가 충분치 않아 현실적으로 어도기능을 위한 합리적인 배수암거 설계기준을 마련하기가 어려운 실정이다. 본 연구의 목적은 배수암거의 평상시 어도기능을 위한 설계유속을 제시하기 위해 국내 하천의 우점종이자 국지회유성 어종인 피라미의 유영특성을 분석하고자 함이다. 피라미의 유영특성을 파악하기 위한 실험은 증진유속방법(incremental velocity test)과 고정유속방법(fixed velocity test)을 병행하여 수행하였다. 실험 결과 피라미(체장 8.9cm)의 유영특성 중 한계유영속도는 0.7 m/s 정도로 나타났다. 따라서 홍수기를 제외한 평상시 유량조건에서 배수암거 설계유속은 피라미(체장 8.9cm)를 대상어종으로 할 경우 0.7 m/s 를 초과하지 않아야 할 것으로 판단된다. 최소수심은 등지느러미까지 충분히 물속에 잠길 수 있는 수심이 필요한 것으로 파악되었다.

Purpose: Previous studies have suggested that BDNF has a role in plasticity and survival following spinal cord injury and treadmill exercise increases BDNF levels in the normal brain and spinal cord. We attempted to determine whether swimming exercise improve motor function following experimental contusive spinal cord injury and whether motor outcome is associated with BDNF expression. Methods: Thirty six Sprague-Dawley rats (weight, 250 to 300 g) were divided into control (n=18) and experimental swimming group (n=18). Spinal cord injury was produced using NYU-spinal impactor at the eleven thoracic levels in both groups. Swimming exercise started $7^{th}$ day from SCI operation, lasted 5 min per day, 5 days a week for 4 weeks and then exercise times a day were increased in one number to each week. Motor functional recovery was determined by the Basso-Beattie-Bresnahan (BBB) locomotor rating scale, modified inclined board plane test, histological findings, H&E and BDNF expression observed at $1^{th}$, $3^{rd}$, $7^{th}$, $14^{th}$, $21^{st}$ and $28^{th}$day after injury. Results: 1. The BBB scores were higher in experimental group than control group at $14^{th}$, $21^{st}$ day (left hind limb) and at $21^{th}$ day (right hind limb) (p<0.05) after injury. 2. The inclined board plane test were significantly greater in experimental group than control group at $7^{th}$ day (p<0.05), $14^{th}$ and $28^{th}$ day (p<0.01) after injury. 3. The BDNF expression was severe revealed in experimental group than control group at $7^{th}$, $14^{th}$ and $28^{th}$ day after injury. Conclusion: This study suggests that swimming applied from the early phase after spinal cord injury be beneficial effects in motor functional recovery.

The present study was aimed at investigating the effect of swimming training on brain function after focal cerebral ischemia in rats. Therefore, this study was examined on neurogenesis in dentate gyrus of hippocampus using 5-bromo-2'-deoxyuridine (BrdU) to label proliferating cells and assessed the neurological response following focal cerebral ischemia in rats using neurological motor behavioral test. In an observer-blinded fashion, twenty male Sprague-Dawley (280~310 g, 7 weeks old) rats were divided into four groups: MCAO plus swimming group (ME, $n_1$=5), MCAO plus control group (MC, $n_2$=5), SHAM plus swimming group (SE, $n_3$=5), SHAM plus control group (SC, $n_4$=5). The results of this study were as follows: 1) The limb placing time before and after swimming in the ME group were significantly longer than the MC group (p<.05), the SE group were significantly longer than the SC group (p<.01). 2) The balance beam scores before and after swimming in the ME group was higher than the SE group, the MC group was higher than the SC group but was not significantly different (p>.001). 3) The foot fault index before and after swimming training in ME group was significantly lower (i.e., improved) than the MC group (p<.001) and the SE group (p<.001), the SE group was significantly lower (i.e., improved) than the SC group (p<.001). 4) The mean number of BrdU-positive cells in the dentate gyrus in the ME group was significantly higher than the MC group (p<.001) and the SE group (p<.01). The MC group and the SE group was significantly higher than the SC group (p<.001). 5) There was significantly correlation between limb placing time and number of BrdU-positive cells on swimming training, there was positive correlation (r=.807, p<.0001) and between foot fault index and BrdU-positive cells number, there was negative correlation (r=-.503, p<.05). However, between balance beam scores and BrdU-positive cells number, there was no correlation. In conclusion, the present study demonstrates that the role of swimming training improves behavioral motor function probably by enhancing cell proliferation in that hippocampus. This study provides a model for investigating the stroke rehabilitation that underlies neurogenesis and functional ability.
