Abstract

Erectile dysfunction (ED), also known as impotence, is the inability to attain and sustain an erection firm enough to have sexual intercourse. Frequent ED may be a symptom of health problems including heart disease, obesity, alcoholism, stress, smoking, and depression, that need treatment. This study aimed to effect of complex extract (CPL) including Cornus officinalis on sexual function factor in the erectile dysfunction rat model. The erectile dysfuction rat model was induced by cimetidine (500 mg/kg in 5% ethanol, oral injection 2 weeks). Rats were oral administered with different concentration of CPL in rat erectile dysfunction model. As a results, sexual function factors (NO, cGMP) significantly improved in CPL treated groups (CPL-300, 600, 900 mg/kg) compared to CON group. Serum testosterone was increased in a dose-dependent manner after CPL treatment. Furthermore, administrations of CPL restored lumen areas of the prostate in the erectile dysfunction rat model. These results indicated that CPL alleviated erectile dysfunction by increasing sexual function factor and testosterone in rat model. CPL could be used to natural treatement for erectile dysfunction. However, further study is required to identify active ingredient and its mechanism of erectile dysfunction.

발기부전(erectile dysfunction, impotence)은 성교과정을 위한 음경이 딱딱하게 발기되지 않거나 유지하지 못하는 것을 말한다. 잦은 발기 부전은 심장 질환, 비만, 알코올 중독, 스트레스, 흡연 및 우울증을 비롯하여 치료가 필요한 건강상의 문제가 원인이 된다. 본 연구는 산수유(Cornus officinalis)를 포함한 복합 추출물이 발기부전 랫드모델에서 성기능과 관련된 인자에 미치는 영향을 알아보고자 하였다. 발기부전 랫드모델은 Cimetidine/5% EtOH를 2주 동안 경구투여하여 유도한 후, 산수유 등 복합추출물을 각각 다른 농도로 경구투여하였다. 그 결과, 산수유 등 복합추출물 처리군(CPL-300, 600, 900 mg/kg)에서 성 기능 인자(NO, cGMP)가 대조군에 비해 유의성 있게 향상되었다. 또한 혈청 테스토스테론은 산수유 등 복합추출물 처리 후 용량 의존적으로 증가하였다. 더욱이, 산수유 등 복합추출물의 투여는 발기부전 랫드모델에서 전립선의 크기를 회복시키는 것을 확인하였다. 결과를 종합하자면 산수유 등 복합추출물이 랫드모델에서 성기능 인자와 테스토스테론을 증가시킴으로써 발기부전을 완화시킨다는 것을 보여 주었고, 이는 산수유 등 복합추출물이 천연 추출물로 향 후 발기부전 치료에 사용될 수 있음을 시사한다. 하지만 산수유 복합추출물의 남성 성기능의 직접적인 연관관계, 유효성분과 그 메커니즘을 자세히 밝히기 위해서는 추가적인 연구가 필요하다고 사료된다.
