Abstract

精漿中のSOD様活性および希釈保存精液中のSOD様活性について検討した。雄ブタA, Bの精漿中のSOD様活性値は, それぞれ9.73±0.88U/m<i>l</i>および6.06±0.23U/m<i>l</i>であった。また希釈保存精液中のSOD様活性値には, 保存日数の経過に伴う変化は認められなかった。精子の運動性に対するSOD添加の効果は低濃度では認あられなかったが, 800U/m<i>l</i>を添加した場合, 保存14日目までの精子の運動性は高く維持され, 対照区と有意な差を認めなかった。

The purpose of this experiment was to evaluate <i>the superoxide dismutase (SOD)-like activity</i> of boar seminal plasma, the change of <i>SOD-like activity</i> in the semen stored in Modena extender during preservation and to clarify the effect of addition of SOD to Modena extender on the motility of boar spermatozoa. <i>The SOD-like activity</i> was measured by Electron Spin Resonance Spectroscopy. <i>The SOD-like activities</i> of seminal plasma of boar A and B were 9.7±0.9μ/m<i>l</i> and 6.1±0.2μ/m<i>l</i>, respectively. <i>The SOD-like activity</i> in the semen diluted with Modena extender did not change during the storage period of 28 days at 10°C. The addition of SOD to the extended semen improved sperm viability during storage of 28 days and the best result was obtained from the spermatozoa suspended in Modena extender added 800μ/m<i>l</i> of SOD. <i>The results suggest that the addition of SOD to Modena extender is useful for long-term maintenance of good motility in liquid storage of boar spermatozoa</i>.
