研究了在最佳降温复温过程中，抗冻剂DMSO质量浓度变化对小牛主动脉低温保存后细胞活性和功能的影响．实验结果表明：DMSO质量浓度为15kg/m3时，血管保存效果最好，70％的血管组织超微结构保存完好．冷冻血管对量浓度为1μmol/Lnorepinephrine的收缩力降到新鲜血管的90％。左右，对同样量浓度acetylcholine的舒张力降到新鲜血管的30％～40％，复温后动脉血管的其他功能保持完好．
In the process of optimal cooling and rewarming, the effect of antifreeze DMSO concentration on the cell viability and function of calf aorta after cryopreservation was studied. The experimental results show that when the mass concentration of DMSO is 15kg / m3, the best preservation of blood vessels, 70% of vascular tissue ultrastructure preservation intact. The contractile force of frozen blood vessels at a concentration of 1 μmol / L norepinephrine was reduced to 90% of fresh blood vessels. , The same amount of concentration of acetylcholine diastolic blood pressure dropped to 30% to 40%, after rewarming the other functions of the arteries remain intact.
