现代生理学、药理学、生物化学一些资料证明,乙酰胆硷在神经传递(特别是传出神经传递)活动中起重要作用,所以研究分解它的乙酰胆硷酯酶对于了解神经活动有很大意义。以往,用组织化学方法研究胆硷酯酶的报导不少,但是最常用的方法多系 Koelle 乙酰硫胆硷和丁酰硫胆硷法以及 Gomori 氏改良法。前者步骤繁琐,后者较为简便。乙酰硫 Modern physiology, pharmacology, biochemistry Some data prove that acetylcholine plays an important role in the activity of neurotransmission (especially the afferent nerve transmission), so studying the acetylcholinesterase that breaks down it is of great significance for understanding the neural activity . In the past, the histochemical method of cholinesterase reported a number of reports, but the most commonly used method Kolex acetylcholine and butyrylcholine choline and Gomori’s improved method. The former steps tedious, the latter is more simple. Acetyl sulfur
