The purpose of this study was to examine the effects of taurine and vitamin E on sperm characteristics damaged by bromopropane (BP) in pig. We evaluated toxicity of BP on viability, membrane integrity and mitochondrial activity of spermatozoa. 1-BP (0, 2.5, 5.0, 10, and $50{\mu}M$), 2-BP (0, 2.5, 5.0, 10, and $50{\mu}M$), taurine (0, 5.0, 10, and $25{\mu}M$) and vitamin E (0, 50, 100, and $200{\mu}M$) were treated in fresh boar semen for 6 h. 10 and $50{\mu}M$ of 1-BP and 2-BP inhibited sperm viability, membrane integrity and mitochondrial activity in fresh boar semen (P<0.05). $25{\mu}M$ of taurine increased sperm viability and membrane integrity (P<0.05), $100{\mu}M$ of vitamin E enhanced viability and mitochondrial activity of sperm (P<0.05). Finally, $10{\mu}M$ of 1-BP and 2-BP was co-treated with taurine ($25{\mu}M$) and vitamin E ($100{\mu}M$) in the fresh boar semen. The co-treated samples did affected viability, membrane integrity and mitochondrial activity of sperm. In conclusion, taurine and vitamin E can improve and maintain sperm quality in fresh boar semen.

대상 데이터
1-Bromopropane (1-BP), 2-bromopropane (2-BP), taurine and vitamin E were purchased from Sigma-Aldrich (St. Louis, Missouri, USA). Bore semen was collected from the local AI center (Wonju, Kangwon, Korea), diluted to concentration of 3.
데이터처리
Data were compared for differences using of Duncan’s mo- dified multiple range tests using Statistical Analysis System software version 9.2 (SAS Institute Inc. USA).
성능/효과
In conclusion, bromopropane can promotes oxidative stress via excess oxygen and inhibition of antioxidant enzymes, but taurine and vitamin E may maintain sperm viability and quality in the boar fresh semen.
