摘 要：
研究了超低温冷冻保存(-196℃)对俄罗斯鲟(Acipenser gueldenstaedti)精浆和精子中总三磷酸腺苷酶(AT-Pase)、琥珀酸脱氢酶(SDH)、乳酸脱氢酶(LDH)、肌酸激酶(CK)等酶活性的影响,并分别测定了冷冻前后俄罗斯鲟精浆和精子中酶的活性。结果显示,经过超低温冷冻保存后,俄罗斯鲟精子活力下降,精子内各酶活性均显著降低,添加冷冻保护液组精子中总ATPase、SDH、LDH和CK的活性分别从(198.47±14.43)U/mL、(30.00±2.65)U/mL、(6 982.29±24.32)U/L和(1.94±0.05)U/mL下降至(110.19±2.32)U/mL、(16.33±2.08)U/mL、(5 122.93±195.07)U/L和(1.49±0.14)U/mL。未添加抗冻剂组则分别下降至(2.25±0.33)U/mL、(11.67±0.58)U/mL、(4 488.04±78.33)U/L和(1.16±0.02)U/mL;精浆中酶的活性均显著升高,添加冷冻保护液组精浆总ATPase、SDH、LDH和CK活性分别从(12.70±0.57)U/mL、(7.50±0.71)U/mL、(2017.26±116.81)U/L和(2.93±0.59)U/mL升高至(92.49±5.18)U/mL、(13.33±0.58)U/mL、(3 688.97±172.67)U/L和(4.39±0.24)U/mL,未添加抗冻剂组则分别上升至(200.27±12.97)U/mL、(24.67±3.06)U/mL、(6 124.40±329.14)U/L和(5.20±0.16)U/mL。结果表明,超低温冷冻对俄罗斯鲟精浆和精子中酶活性及精子活力均有较大影响。

摘 要：
The effects of cryopreservation(-196 ℃) on were studied,and the activities of enzyme in the enzyme′s activities(total ATPase,SDH,LDH and CK) in seminal plasma and spermatozoa of Acipenser gueldenstaedti.The changes of enzyme′s activities were the seminal plasma and spermatozoa were determined hefore and after cryopreservation.The results showed that the motility of spermatozoa dropped after cryopreservation,the activities of enzyme in spermatozoa descended significantly(P<0.05),and the activities of total ATPase,SDH,LDH,CK in spermatozoa in cryoprotectant group dropped from(198.47±14.43)U/mL,(30.00±2.65)U/mL,(6982.29±24.32)U/L and(1.94±0.05)U/mL to(110.19±2.32)U/mL,(16.33±2.08)U/mL,(5122.93±195.07)U/L and(1.49±0.14)U/mL,respectively.The activities of enzyme in spermatozoa without cryoprotectant dropped to(2.25±0.33)U/mL,(11.67±0.58)U/mL,(4488.04±78.33)U/L and(1.16±0.02)U/mL,the activities of enzyme in seminal plasma increased significantly(P<0.05),the activities of total ATPase,SDH,LDH,CK in seminal plasma in cryoprotectant group rose from(12.70±0.57)U/mL,(7.50±0.71)U/mL,(2017.26±116.81)U/L and(2.93±0.59)U/mL to(92.49±5.18)U/mL,(13.33±0.58)U/ml,(3688.97±172.67)U/L and(4.39±0.24)U/mL,respectively.The activities of enzyme in seminal plasma without cryoprotectant rose to(200.27±12.97)U/mL,(24.67±3.06)U/mL,(6124.40±329.14)U/L and(5.20±0.16)U/mL.It was indicated that the activities of enzyme and the motility of spermatozoa of A.gueldenstaedti were greatly offected by cryopreservation.
