초록

Collagen 유발(誘發) 관절염(關節炎) 동물모델을 이용하여 족삼리(足三里) (ST36) 봉독약월(蜂毒藥鉞)의 진통효과(鎭痛效果)와 그 기전(機轉) 을 관찰하기 위하여 TFL을 지표로 하여 통증 역치의 변화와 naloxone 및 yohimbine으로 전처(前處) 치한(置) 후 (後) 봉독약침(蜂毒藥鍼)의 진통효과(鎭痛效果)를 관찰한 결과 다음과 같은 결론을 얻었다. 1. Collagen 유발(誘發) 관절염(關節炎)의 rat에서 TFL 통증 역치는 1, 2, 3 및 4주로 갈수록 지속적 감소를 나타내었다. 2. 1회와 2주간 봉독약철(蜂毒藥鐵)은 collagen 유발(誘發) 관절염(關節炎) rat의 통증역치를 각각 증가시켰다. 3. CIA rat에 opioid receptor antagonist인 naloxone을 투여한 후 봉독약침(蜂毒藥鍼)을 처치한 결과 진통효과(鎭痛效果)가 유지되는 것으로 보아 봉독약광(蜂毒藥鑛)의 진통기전(鎭痛機轉)은 아편양 기전(機轉)과 관련이 없는 것으로 사료된다. 4. CIA rat에 ${\alpha}2$-adrenoceptor antagonist인 ohimbine을 투여한 후 봉독약침(蜂毒藥鍼)을 처치한 결과 진통효과(鎭痛效果)가 길항(拮抗)되는 것으로 보아, 봉독약침(蜂毒藥鍼)의 기전(機轉)은 ${\alpha}2$-adrenoceptor에 의하여 매개는 것으로 사료된다.

Objective : The aim of this study is to investigate the analgesic effect and its mechanism of bee venom acupuncture on collagen-induced arthritis(CIA) rats. Methods : Bee venom (1 mg/kg) was subcutaneously punctured into Choksamni (ST36) of CIA Analgesic effect was evaluated by using the tail flick latency (TFL). Opioid and ${\alpha}2$-adrenergic neurotransmitter system were examined by naloxone as an opioid receptor antagonist and yohimbine as ${\alpha}2$-adrenoceptor antagonist prior to bee venom cupuncture. Results : The results were as follows; 1. The TFL for the CIA rat was decreased as time went by. 2. The TFL in CIA rat was increased in bee venom acupuncture group compared with control group (no treatment). 3. Analgesic effect of bee venom acupuncture was not abolished by naloxone pre-treatment in the CIA rat. 4. Analgesic effect of bee venom aqua-acupuncture was abolished by yohimbine pre-treatment in the CIA rat. 5. Two weeks bee venom acupuncture had the continous analgesic effect for 4 weeks. Conclusions : Bee venom acupuncture has an analgesic effect on the CIA rat and has an antinociception mediated by ${\alpha}2$-adrenergic system.
