Hi Sharron:

    You can use acetaldehyde instead of paraldehyde but you must use 
three times as much (one paraldehyde dissociates to 3 acetaldehydes in 
the stain). See "Staining properties of aldehyde fuchsin analogs" by 
Buehner et al. J. Histochem. Cytochem 27(3);782-787, 1979.
    If you can get your pathologist to write an Rx for parladehyde get 
in the little ampoules so you always have fresh. Using acetaldehyde is 
easier! And make sure your "basic fucsin" is really pararosanaline.
