尼古丁与乙酰胆碱相互作用，乙酰胆碱是一种胎儿时期大脑发育的重要神经递质和信使。
The nicotine interacts with acetylcholine, which is an important neurotransmitter and messenger when the brain is developing during the foetal stage.
这些药物通过抑制在神经肌肉接合部位水解乙酰胆碱的乙酰胆碱酯酶的活性而发挥效应。
These drugs exert their effect by inhibiting the activity of acetylcholinesterase, the enzyme that hydrolyzes acetylcholine in the neuromuscular junction.
结果正常组肝组织内乙酰胆碱受体含量明显低于模型组（P<0.01），且和络舒肝组乙酰胆碱受体含量低于模型组（P<0.05）。
Results The level of acetylcholine receptorswas obviously lower in the control group than in the model group(P<0.01), and lower in the HLSG-treated group than in the model group(P<0.05).
最后，用乙酰胆碱离子选择性微电极测定了束缚紧张状态模型大鼠红细胞内的乙酰胆碱活度。
Finally, using the microelectrode sensitive to ACh, the ACh activity in red cells of rat in nervous state was measured.
更多的研究表明乙酰胆碱酯酶抑制细胞的增殖是通过催化和降解乙酰胆碱的酶活性来实现的。
Further study showed that ACHE suppressed cell proliferation via its enzymatic activity of acetylcholine catalysis and degradation.
