Abstract

This study was designed to investigate the effects of KH204 on the relaxation response and reproductive function in male. Strips of rabbit corpus cavernosum were prepared for mounting and isometric tension measurement in an organ bath. On cavernosal strips contracted with $1{\times}10^{-6}$ phenylephrine and KH204 was applied in increasing concentrations from 0, 61, 183 and 549 mg/L, causing dose-dependent relaxation. Male Sprague-Dawley rats were orally administered with 61, 183 and 549 mg/kg/day of KH204 for 10 weeks. We examined organ weights, testicular sperm head counts, epididymal sperm counts, motility and morphology. KH204 relaxed rabbit corpus cavernosal strip contracted by $1{\times}10^{-6}$ phenylephrine in a dose-dependent manner. In the male rat, testicular weight was increased significantly in the KH204 treated groups compared with control group. Also in the testicular sperm head counts, epididymal sperm counts were increased significantly in the KH204-treated rats. In conclusion, the data suggest that KH204 could enhance erectile and reproductive function.

KH204가 음경해면체 이완과 생식기능에 미치는 영향을 규명하기 위해 효능을 실험한 결과 토끼의 음경해면체를 $1{\times}10^{-6}M$ pheylephrine으로 수축시킨 후 KH204를 61, 183 및 549 mg/L의 축적용량으로 처리하여 각각 6.8, 10.1 및 16%의 용량의존적인 이완효과를 관찰하였다. 흰쥐를 이용한 생식기능 실험은 KH204를 61, 183 및 549 mg/kg으로 10주간 장기투여에서 생식장기인 고환조직의 중량 및 정자수 증가에 유의한 효과를 나타내었다. 정자 형태검사는 대조군과 비슷한 수치로 나타내어 고농도로 장기투여에도 정자군과 비슷한 수치로 나타내어 고농도로 장기투여에도 정자 기형에 문제가 없음을 확인하였다. 이상의 결과로 KH204가 특별한 부작용이 없이 음경해면체를 농도의존적으로 이완시키는 효과가 있어, 음경발기를 개선시키는 효과뿐만 아니라 고환성 원인 또는 정자생산 기능부전으로 보이는 남성불임에서 또한 효능이 있음을 시사하였다.
