【摘要】 应用体外细胞培养研究了西蕃莲(edulis,f.fisvianpa)对二倍体细胞DNA合成的作用。结果表明25PD之后,实验组与对照组的细胞DNA合成量有明显差别,实验组35PD时CPM值比对照组的25PD时还高,二者之间相差5～10个PD。此外,细胞DNA合成速率及细胞DNA的降减率也表明西蕃莲具有保持细胞较旺盛的增殖能力和推迟细胞衰老的作用。更多还原

【Abstract】 Effect of passionflower on DNA synthesis of cultured diploid cells in vitro was studied, Results showed that there were significant difference in the DNA synthesis between experiment and control groups after 25 population doubling. The CPM value of experiment group in 35 population doubling was still higher than that of control group in 25 population doubling, showing the former delayed 5-10 population doubling. Moreover, the DNA synthesis and decrease rate also demonstrated that passionflower could keep exuberant cell proliferating effect and delay cell senescence.更多还原
