neither alcian blue nor aldehyde fuchsin revealed oxidatively generated aldehyde as judged by 1 ) their failure or near failure to stain inferior olive lipofuscin following mildly applied periodic acid , and 2 ) the increase in staining intensity , from moderate to strong , displayed by the soluble lipid-free lipofuscin component of neuromelanin and by inferior olive lipofuscin when potassium permanganate was followed by a rinse with metabisulfite or bisulfite in place of one with oxalic acid .
