The effects of Bogi, Boyang and Onri herbs on glutamte receptor, and the regulatory mechanism of cAMP-protein kinase on the ion currents activated by Bogi, Boyang and Onri herbs using nystatin-perforated patch clamp were investigated and the following results were obtained. Ginseng radix and Astragali radix, Cervi cornu and Boshniakiae herba, and Aconiti tuber and Zingiberis rhizoma were chosen as Bogi, Boyang and Onri herbs respectively. 1. The ion currents activated by $10^{-5}M$ of glycine were used as controls. The magnitudes of the ion currents by the above named herbs were as follows; Cervi cornu>Astragali radix>Aconiti tuber>Zingiberis rhizoma>Ginseng radix>Boshniakiae herba. 2. The magnitudes of the ion currents by $10^{-5}M$ of glutamate pre-treated with 0.01 mg/ml of Bogi, Boyang and Onri herbs were sharply decreased. 3. The activity of ion channels activated by Bogi herbs pre-treated with $10^{-7}M$ of staurosporin, an inhibitor of protein kinase, for thirty seconds was observed as the experiment proceeded. Staurosporin brought about dephosphorylation of ion channels. Hence, while the activity of ion channels activated by Ginseng radix was decreased, the activity of ion channels activated by Astragali radix was increased, as time went by. 4. The activity of ion channels activated by Boyang herbs pre-treated with $10^{-7}M$ of staurosporin, an inhibitor of protein kinase and an dephosphorylating agent of ion channels, for thirty seconds was investigated. While the activity of ion channels activated by Cervi cornu was increased, the activity of ion channels activated by Boshniakiae herba was initially increased then sharply decreased. 5, The activity of ion channels activated by Onri herbs pre-treated with $10^{-7}M$ of staurosporin, an inhibitor of protein kinase and an dephosphorylating agent of ion channels, for thirty seconds was investigated. While the activity of ion channels activated by Aconiti tuber was increased, that of ion channels activated by Zingiberis rhizomal sharply declined.

말초신경은 외상이나 질병 등 여러 가지 원인으로 손상되기 쉬우며, 손상의 정도가 심하거나 치료가 지연되는 경우에는 심각한 기능 소실을 초래할 수 있다. 본 연구에서는 수영이 말초신경손상후 운동기능의 회복과 뇌유인성 신경영양인자 (brain-derived neurotrophic factor, BDNF) mRNA의 발현에 미치는 효과를 알아보기 위하여, 흰쥐 좌골신경에 압박 손상을 가하고 수영을 적용한 후 보행궤적분석 (walking track analysis)과 역전사연쇄반응 (reverse transcription-polymerase chain reaction, RT-PCR)을 실시하였다. 그 결과, 좌골신경 압박손상된 쥐는 특징적인 보행패턴을 나타내어 좌골신경기능지수 (sciatic function index, SFI)가 현저히 낮아졌으며, BDNF mRNA의 발현이 증가하였다. 좌골신경 압박 손상후 수영을 한 쥐에서는 SFI가 현저히 향상되었으며, BDNF mRNA의 발현은 억제되었다. 이러한 결과는 말초신경손상후 수영이 BDNF mRNA의 발현을 조절함으로써 기능 회복을 촉진시키는 효과적인 치료방법이 될 수 있음을 제안하고 있다.
