摘要/Abstract

摘要： 为了提高猪成熟卵母细胞细胞玻璃化冷冻效果。本试验拟添加紫杉醇，比较其对冷冻环冷冻效果的影响。结果显示使用1.0 μmol·L1紫杉醇预处理卵母细胞，冷冻后其形态完整率(89.93%)和FDA染色存活率(83.33%)都显著高于未处理组的79.12%和70.97%（P<0.05），继续提高紫杉醇浓度则表现为对卵母细胞的毒副作用。在不同预处理时间上，预处理30 min组冷冻后卵母细胞形态完整率和FDA染色存活率最高，分别达到90.21%和84.13%。预处理浓度1.0 μmol·L1，30 min是比较合适的处理方法；紫杉醇、细胞松弛素B（CB）或两者联合添加能显著提高猪成熟卵母细胞的玻璃化冷冻的效果（P<0.05），但两者之间没有显著差异（P>0.05）。

Abstract: The aim of this study was to improve the effect of vitrification of porcine matured oocyte. This study was designed to examine the effect of Taxol pretreatment on vitrification of porcine oocytes matured in vitro by a cryoloop method. The results showed that the vitrified oocytes pretreated with 1.0 μmol·L1 Taxol attained higher normal morphology rate(89.93%) and FDA stain survival rate(83.33%) than the control(79.12% and 70.97%) (P<0.05). But when the concentration of Taxol was increased, it came to weaken the effect of vitrification. The proportions of oocytes with normal morphology and survive rates could reach to 90.21% and 84.13%, when they were treated for 30 minutes before vitrification. So the best parameter was 1.0 μmol·L1 Taxol for 30 minutes before vitrification. Pretreatment with CB or Taxol had a significant positive effect on vitrification of porcine matured oocytes(P<0.05), but there were no significant differences between the two chemical materials(P>0.05).
