Abstract

This study was aimed to investigate the effect of phyto-extract fermented mixture (MP119) on the male sexual functions. The MP119 was evaluated for anti-impotency and anti-hypertensive effects via ACE (angiotensin converting enzyme) or PDE (phosphodiesterase) inhibition assay. $IC_{50}$ values of MP119 against ACE and PDE were 241.3${\pm}$35.5 ppm and 372.2${\pm}$33.8 ppm, respectively. To investigate the effect of testosterone expression by MP119, we performed cell media test using mouse Leydig-derived TM3 cells. Production of testosterone in TM3 cell was increased by MP119. Also, NO (nitric oxide) production of HUVEC (human umbilical vein endothelial cell) was increased when MP119 was added to the cultures. Forty male ICR mice were divided into 4 groups. MP119 was orally intubated for 7 days to group 1 and 3, and same volume of vehicle to group 2 and 4 as controls. After that, group 3 and 4 were intraperitoneally injected cadmium chloride at a single dose of 2 mg/kg. On the 8th experimental day, weights of testis, epididymis and seminal vesicle, number of sperm, concentrations of serum testosterone and cGMP were determined. The number of sperm, the concentrations of testosterone and cGMP were significantly increased in two experimental groups (group 1, 3). These results suggest that MP119 enhanced the sexual function of male mice, and could protect the sexual organs from the cadmium chloride as one of the endocrine disrupters.

마카, 홍삼, 남가새 추출물을 일정한 무게 비율로 혼합하여 발효시켜 얻어진 식물추출복합발효물(MP119)이 성기능에 미치는 영향을 조사하였다. ACE(angiotensin converting enzyme)과 PDE(phosphodiesterase)에 대한 저해효과를 통해 혈액순환부진 개선 및 cGMP 농도에 의한 발기능 개선에 미치는 효과를 측정하였다. MP119의 ACE 저해효과를 측정한 결과 $IC_{50}$값이 241.3${\pm}$35.5 ppm, PDE 저해효과를 측정한 결과 $IC_{50}$값이 372.2${\pm}$33.8 ppm으로 나타나 혈관확장으로 인한 혈류량 증가 및 cGMP농도 증가에 영향을 줄 수 있을 것으로 예상된다. MP119는 마우스 정소세포인 TM3 cell에 유의성 있는 독성이 나타나지 않았으며, TM3 cell에 농도별로 처리했을 때 세포배양액으로부터 대조군과 비교하여 최대 20.11% 증가한 testosterone 농도를 확인하였다. 또한 HUVEC에 농도별로 처리했을 때 NO생산량이 MP119 처리 농도가 증가할수록 유의성 있게 증가하였다. 웅성마우스에 MP119를 7일간 경구투여 후 생식장기의 무게와 정자수를 측정하고, MP119를 경구투여한 후 염화카드뮴을 투여하여 생식장기의 무게와 정자수를 측정하였다. 또한 실험쥐로부터 혈청을 분리하여 혈청 내 testosterone과 cGMP를 측정하였다. 그 결과 MP119의 투여를 통해 생식장기의 무게 변화 없이 정자수 증가에 도움을 준다는 것을 확인하였으며, 더불어 혈청 내 testosterone 및 cGMP의 농도 역시 증가하였다. MP119를 투여한 후 염화카드뮴을 투여한 실험군에서 역시 정자수 및 혈청 내 testosterone, cGMP 농도 증가를 나타내었으므로 결과적으로 MP119가 염화카드뮴의 독성예방 및 치료에 효과적임을 확인하였다.
