Results 2 ClAdo and 2 CldAdo had different cytotoxicities on the cells, while 2' dAdo had no cytotoxicity on the cells. 2 CldAdo blocked the cell growth at the phase of S and G2/M, while 2 ClAdo at the phase of G0/G1. 2 CldAdo mainly induced cell necrosis, while 2 ClAdo induced both cell necrosis and apoptosis. Down regulated Bcl 2 expression and up regulated p53 and Bax expression were associated with 2 ClAdo, while 2 CldAdo down regulated Bcl 2 expression and up regulated mildly p53 expression without any effect on Bax expression.

结果 2 ClAdo、2 CldAdo对所研究的细胞均有程度不等的毒性；2' dAdo对各细胞生长、增殖均无明显抑制（c=100 μmol/L即30 μg/mL内）；2 CldAdo明显阻断细胞于S、G2/M期，2 ClAdo阻断细胞于G0/G1期；2 CldAdo 致细胞坏死为主，2 ClAdo 既致细胞坏死又诱导凋亡；2 ClAdo 下调Bcl 2，上调P53、Bax蛋白表达；2 CldAdo小幅上调P53、小幅下调Bcl 2，不影响Bax蛋白表达。

In order to verify nicotine effect to heart of rat , analyzing the electrograph Based on these results , it was demonstrated that nicotine can induce to release acetylcholine locally or act on muscarinic cholinoreceptor controlled by parasympathetic nerve .

为进一步确定烟碱对大鼠心脏的作用，对描记烟碱作用后大鼠心电图进行分析，发现烟碱能引起大鼠心电图显示较长的QT间期，增加了PR间期及T波面积，与肾上腺素或去甲肾上腺素引起的QT间期延长相似，且能被M受体阻断剂阿托品所阻断，说明烟碱能够诱导局部释放乙酰胆碱或者作用于部分副交感神经控制的毒蕈碱受体。
