Hi, generally the good Histochemistry text are very older, and the great masters
in the area that you are interested are Ramon and Cajal, very older!!!. To stain
mielin, the best source is to use post fixation in osmium tetroxide (1% final
concentration) and potasium ferrocyanide(NOT FERRICYANIDE) (1.5% final
concentration). and electron microscopy to observe the results, it's procedure
increase the lipid staining (mielin staining) and it's no difficult. To stain
cholinesterase, there are several methods and this are based on it's activity.
You have to use acetiylthiocholine iodide as substrate (it's the Koelle and
Friedenwald method) and I've good results using this procedure.
