Anti-stress effects of Herbal Acupuncture by Soyo-san on ovariectomized rats

소요산(逍遙散) 약침(藥針)이 흰쥐의 갱년기(更年期) 우울증(憂鬱症) 및 stress모델의 인지, 학습 및 기억장애와 불안행동에 미치는 효능(效能)을 파악하기 위하여 행동실험 학적 검사와 면역조직화학적 검사를 실시한 결과 다음과 같은 결론을 얻었다. 1. Morris water maze의 학습검사결과 Soyo-san군(群)의 경우, 시간단축이 현저하게 나타나서 제 6일째 $24.69{\pm}8.48$초로 측정되어 Ovx군(群)에 대해 유의성 있는 인지 및 학습력을 보였다. 2. Morris water maze의 기억검사결과 Soyo-san군(群)이 $3.38{\pm}0.82$로 Sham군(群)과 Ovx군(群)에 대해 머문 시간이 유의성있게 증가하였다. 3. Ventral tegmental area의 TH의 발현정도는 Normal군(群)이 $9.14{\pm}0.50$, Sham군(群)은 $9.00{\pm}0.29$, Ovx군(群)은 $10.81{\pm}0.63$, Soyo-san군(群)은 $8.19{\pm}0.42$로 나타났는데 Soyo-san군(群)이 Ovx에 대해 유의성있게 감소하였다. 4. Hippocampus의 CAI부위에서는 ChAT 발현 정도에서 Soyo-san군(群)이 On군(群)에 대해서 유의하게 증가하였다. 이상(以上)의 결과를 종합하면 소요산(逍遙散) 약침(藥針)이 난소 적출 흰쥐의 stress모델의 인지, 학습 및 기억장애를 호전시키는 것으로 나타났으며 이는 갱년기(更年期) 여성(女性)의 우울증(憂鬱症) 및 stress 반응에 대한 적절한 치료제로서 가능하리라 사료된다.
