EFFECTS OF THREE DIFFERENT CRYOPROTECTANTS ON OXIDATIVE STRESS OF RABBIT SEMEN DURING
CRYOPRESERVATION
Glycerol, DMSO and acetamide are three cryoprotectants commonly used in the process of
cryopreservation of rabbit semen. In this study, these three cryoprotectants with concentration of 4%
were tested for their effect on oxidative stress of rabbit sperm. After thawing, the oxidative stress was
evaluated by five indicators: level of carbonyl groups and malondialdehyde, activity of superoxide
dismutase (SOD), glutathione reductase (GR) and glutathione peroxidase (GSHPX). The results
showed that glycerol provided the lowest protection to GR (P
