This study was conducted to investigate the influence of superoxide dismutase (SOD) on the quality of boar semen during liquid preservation at 17°C. Semen samples from 10 Duroc boars were collected and pooled, divided into five equal parts and diluted with Modena containing different concentrations (0, 100, 200, 300 and 400 U/mL) of SOD. During the process of liquid preservation at 17°C, sperm motility, acrosome integrity, membrane integrity, total antioxidant capacity (T‐AOC) activity, malondialdehyde (MDA) content and hydrogen peroxide (H2O2) content were measured and analyzed every 24 h. Meanwhile, effective survival time of boar semen during preservation was evaluated and analyzed. The results indicated that different concentrations of SOD in Modena showed different protective effects on boar sperm quality. Modena supplemented with SOD decreased the effects on reactive oxygen species on boar sperm quality during liquid preservation compared with that of the control group. The added 200 U/mL SOD group showed higher sperm motility, membrane integrity, acrosome integrity, effective survival time and T‐AOC activity. Meanwhile, the added 200 U/mL SOD group showed lower MDA content and H2O2content. In conclusion, addition of SOD to Modena improved the boar sperm quality by reducing oxidative stress during liquid preservation at 17°C and the optimum concentration was 200 U/mL. 相似文献

This study aimed to investigate the effects of bovine serum albumin (BSA) on boar sperm quality during liquid storage at 17°C. Boar semen samples were collected and diluted with Modena containing different concentrations (0, 1, 2, 3, 4, 5 and 6 g/l) of BSA, and sperm motility, plasma membrane integrity, acrosome integrity, total antioxidative capacity (T‐AOC) activity and malondialdehyde (MDA) content were measured and analysed. The results showed that Modena supplemented with 3, 4 and 5 g/l BSA could improve boar sperm motility, effective survival time and plasma membrane integrity (p < 0.05), decrease MDA content (p < 0.05), while no statistical difference was observed for sperm acrosome integrity and T‐AOC activity among these three groups (p > 0.05). The semen sample diluted with Modena containing 4 g/l BSA could achieve optimum effect, and sperm survival time was 7.5 days. After 7 days preservation, sperm motility, plasma membrane integrity and acrosome integrity were 54%, 49% and 78%, respectively. T‐AOC activity and MDA content were 1.03 U/ml and 17.5 nmol/ml, respectively. In conclusion, Modena supplemented with BSA reduced the oxidative stress and improved the sperm quality of boar semen during liquid storage at 17°C, and 4 g/l BSA was the optimum concentration. Further studies are required to obtain more concrete results on the determination of antioxidant capacities of BSA in liquid preserved boar semen. 相似文献

Spermatozoa are highly specialized cells, and energy metabolism plays an important role in modulating sperm viability and function. Rosiglitazone is an antidiabetic drug in the thiazolidinedione class that regulates metabolic flexibility and glucose uptake in various cell types, but its effects on boar sperm metabolism are unknown. In this study, we investigated the potential effect of rosiglitazone against time‐dependent deterioration of boar spermatozoa during liquid preservation at 17°C. Freshly ejaculated semen was diluted with Beltsville Thawing Solution (BTS) containing different concentrations of rosiglitazone, and the motility, membrane and acrosome integrity of sperm were detected. Besides, we measured glucose uptake capacity, l ‐lactate production level, mitochondrial membrane potential, adenosine triphosphate (ATP) content and mitochondrial reactive oxygen species (mROS) production of sperm after boar semen had been incubated with or without rosiglitazone, iodoacetate (glycolysis inhibitor) and rotenone (electron transport chain inhibitor) for 5 days. The addition of rosiglitazone significantly enhanced sperm quality and had a strong protective effect on the sperm membrane and acrosome integrity during storage. BTS containing 50 μM rosiglitazone maintained the total motility of liquid‐preserved sperm above 60% for 7 days. Rosiglitazone improved sperm quality by regulating energy metabolism manner of preserved sperm, protected the sperm mitochondrial membrane potential, enhanced sperm ATP production and in the meanwhile reduced mROS through enhancing glycolysis but not oxidative phosphorylation. The data suggested the practical feasibility of using rosiglitazone for improving boar spermatozoa quality during semen preservation. 相似文献

The purpose of this test was to investigate the effect of salvianic acid A (SAA, CAS No. 76822‐21‐4) on the quality of boar semen during liquid storage at 17°C. The effects of different concentrations of SAA on semen quality and antioxidant capacity were analyzed. Boar semen was diluted with Beltsville Thawing Solution (BTS) containing different concentrations (0, 15, 30, 45, 60, 75 μM of SAA). During the storage period, sperm activity was measured every 24 hr, and plasma membrane integrity, acrosome integrity, total antioxidant capacity (T‐AOC), malondialdehyde (MDA) content, and catalase (CAT) activity were measured at 0, 1, 3, and 5 days. The results from our study suggest that different concentrations of SAA have different effects on semen preservation. Semen samples supplemented with SAA showed reduced effects of oxidative stress on sperm compared to the control samples. Supplementation of 30 μM of SAA significantly improved sperm motility, plasma membrane integrity, acrosome integrity, and antioxidant capacity. However, the addition of SAA to the extender was scarcely beneficial to the improvement of results of artificial insemination with boar semen after liquid preservation. Further studies are necessary in order to demonstrate that SAA has good effects on the liquid preservation of semen. 相似文献

Peroxidation damage induces sublethal injury to boar sperm during the storage process. Taurine has already been demonstrated to protect cells effectively from oxidant‐induced injury. This study was aimed to evaluate the effect of different concentrations of taurine (0.5, 1, 5 and 10 mmol/L) in Modena diluent on boar sperm quality during liquid storage at 17°C. Ejaculates from sexually mature Duroc pigs were collected, pooled and preserved in the Modena containing different concentrations of taurine. Sperm motility, plasma membrane integrity, acrosome integrity, total antioxidative capacity (T‐AOC) activity and malondialdehyde content (MDA) were examined every 24 h. Modena diluent containing taurine suppressed the reduction in sperm qualities during the process of liquid preservation compared with those of the control group. After 5 days of liquid preservation, the addition of taurine at 5 mmol/L had the optimal effect on survival time as well as maintenance of motility, plasma membrane integrity, acrosomal integrity, T‐AOC activity and MDA content. These results may suggest the possibility that the proper addition of taurine to the semen extender improves the swine production system using artificial insemination by the suppressing of sperm damage and subsequent dysfunction during liquid preservation. 相似文献

The aim of this study was to investigate the effects of different concentrations of glutathione in Modena on boar sperm quality during liquid storage at 17°C. Boar semen samples were collected and diluted with Modena containing different concentrations (0, 1, 5, 10, 15 mmol/L) of glutathione. Sperm motility, effective survival period, plasma membrane integrity, acrosome integrity, total antioxidant capacity (T‐AOC) activity, malondialdehyde (MDA) content and hydrogen peroxide (H2O2) content were measured and analyzed. The results showed that Modena supplemented with 1, 5 and 10 mmol/L glutathione improved sperm motility, effective survival period, plasma membrane integrity and T‐AOC, and decreased MDA content and H2O2 content. Meanwhile, the semen sample diluted with Modena containing 1 mmol/L glutathione achieved optimum effect, and effective survival period was 6.1 days. After 5 days preservation, sperm motility, plasma membrane integrity and T‐AOC of the group treated with 1 mmol/L glutathione were all higher than that of other groups. Meanwhile, MDA content and H2O2 content were lower than that of other groups. In conclusion, Modena supplemented with glutathione decreased the oxidative stress and improved the quality of boar semen during liquid storage at 17°C, and 1 mmol/L concentration was the optimum concentration. © 2016 Japanese Society of Animal Science 相似文献
