摘要: 对玻璃化冻存后羊Ovis aries软骨细胞的存活率和琥珀酸脱氢酶(SDH)活性进行了初步研究。结果表明:细胞存活率随着冻存时间的延长而逐渐下降,但下降速度不明显;SDH活性在玻璃化冻存1 ~ 20 d变化幅度较大,20 ~ 30 d下降趋势减弱,保持相对稳定。从各项指标来看,认为玻璃化溶液VSb组的冻存效果最好,在经过5,10, 15,20和30 d的冻存后,其存活率分别为85.47% 1.78%,80.73% 1.81%,78.62% 2.06%, 76.35% 2.58%和73.83% 1.49%,细胞SDH活性吸光度值分别为0.49 0.064,0.444 0.073,0.394 0.039,0.354 0.082和0.339 0.053。该玻璃化冻存方法对长期冻存羊软骨细胞具有一定的实际应用意义。图4表2参17Abstract: The effects of vitrification on survival rate and succinate dehydrogenase(SDH) activity of ovine chondrocytes were studied. Results showed that the SDH activity decreased remarkably within 20 d after vitrification, whereas the survival rate decreased slowly. VSb selected according to the trend of survival rates and vitality of SDH. After being cryopreserved for 5,10,15,20 and 30 days,the survival rates were 85.47% 1.78%,80.73% 1.81%,78.62% 2.06%,76.35% 2.58% and 73.83% 1.49%,and the vitality of SDH showed 0.49 0.064,0.444 0.073,0.394 0.039,0.354 0.082 and 0.339 0.053. This indicated that cryopreservation of ovine chondrocytes by vitrification had some practical value. [Ch, 4 fig. 2 tab. 17 ref.]
