微波固定系统
（实验动物脑内酵素瞬间灭活性系统）
Muromachi Microwave Fixation system
原理与特色：
1. 用微波加热的方式使得神经组织内的酶（ENZYME）去活性，以避免死后变化
（post-mortem changes）持续进展。
2. 此法比用冷冻固定法要来得好：冷冻法需要10-90秒做深入冷冻去活性，这段
期间，深部组织的死后变化（post-mortem changes）已经在进行，因脑表面
的热传导转差。微波法可在更短的时间内去活性。
3. 可以测：
* Acetylcholine乙酰
* Choline
* Cyclic AMP 环腺苷酸
* Cyclic GMP 环林鸟苷
* GABA 伽马氨基丁酸
* DOPA 多巴（二羟基苯）
* 5-HTP 5-羟色胺酸
* Serotonin 血清素
* Endorphin 内啡肽
* Prostaglandin 前列腺素
* Catecholamines and their metabolites 儿茶酚胺及其代谢物
* Phosphorylated Proteins 磷酸化蛋白质
微波固化可以达到下列标准：
1. 可将温度升至75-90摄氏度，使脑部快速固定。
2. 微波能量可有效集中在动物的头部。
3. 各种动物间都可以达到相同的结果。
4. 对操作人员具备严格的保护，此设备相当简单安全
