초록

정액 동결 방법들은 지속적으로 향상되어 왔지만 융해 속도에 대한 연구는 여전히 정립되어 있지 않다. 따라서, 본 연구의 목적은 동결 후 융해 속도가 정액의 기능에 미치는 영향을 알아보고자 하였다. 비글견으로부터 채취된 정액은 동결 보존 후 다른 융해 속도 ($37^{\circ}C$/1분 or $70^{\circ}C$/15초)에서 융해 되었다. 융해 후, 운동성, 생존성, 정상 형태율, 형질막 온전성, phosphatidylserine (PS) translocation, 세포내 $H_2O_2$ 수준을 평가하였다. $70^{\circ}C$에서 융해된 정자는 $37^{\circ}C$에서 융해된 정자에 비해 향상된 정자 운동성, 생존성, 정상 형태율, 세포막 온전성, non-PS translocation을 보였으나(P < 0.05), $70^{\circ}C$와 $37^{\circ}C$에서 융해된 실험군간 세포내 $H_2O_2$ 수준에서 유의적인 차이는 나타나지 않았다(P > 0.05). 결론으로, $70^{\circ}C$에서의 융해는 개 정자 동결 후 정자 기능을 증진시켰으며, 적절한 융해 온도는 동결 정자의 기능을 향상시킬 수 있을 것으로 판단된다.

Sperm cryopreservation methods have been improved over the last few decades. However, an optimized thawing rate has not yet been established. Therefore, we investigated the effect of thawing rate on sperm function after cryopreservation. The ejaculates collected from beagle dogs were cryopreserved and then thawed at two different thawing rates ($37^{\circ}C$ for 1 min or $70^{\circ}C$ for 15 sec). The thawed sperm were evaluated for motility, viability, morphology, plasma membrane integrity, phosphatidylserine (PS) translocation, and intracellular $H_2O_2$ level. The sperm thawed rapidly at $70^{\circ}C$ showed improved motility, viability, normal morphology, plasma-membrane integrity and non-PS translocation compared to the sperm thawed slowly at $37^{\circ}C$ (P < 0.05). However, the intracellular $H_2O_2$ levels were not significantly different between the rapid- and slow-thawed sperm (P > 0.05). In conclusion, sperm rapid thawing at $70^{\circ}C$ could improve the function of cryopreserved canine sperm, and the appropriate thawing rate would enhance the quality of the cryopreserved sperm.
