2. 分别在缺氧前给予精胺，缺氧-复氧后给予精胺、精脒、腐胺。
Spermine was added extracellularly to the bath before anoxia and spermine, spermidine or putrescine was added extracellularly after reoxygenation.

4. 脑梗死急性期腐胺水平随病情加重显著升高，精脒、精胺水平随病情加重而下降。
The severer the condition of cerebral infarction, the higher the putrescine level and the lower the spermidine and spermine levels.

5. 结果SOD可抑制浓缩铀诱发细胞活性迅速下降及DNA链断裂，同时提高细胞内游离精脒含量。
Results SOD significantly reduced the rapid decrease of the cell viability and DNA chain fragmentation when treated with enriched uranium and markedly enhanced the free spermidine of PC12 cell. Concl…
