Pap or HE staining

Papanicolaou or HE staining is one of the methods for examining tumor cells. The two are described in detail: (1) Papillon staining: This method is characterized by cells with polychromatic colors, colorful and colorful. The smear staining has good transparency, clear cytoplasmic granules, and clear nuclei structure, such as squamous epithelial hyperkeratinocytes. The cytoplasm is orange; keratinocytes are pink; and cells before keratinization are light green or light blue. It is suitable for staining epithelial cells or observing the effect of hormone levels on epithelial cells in vaginal smears. The disadvantage of this method is that the staining procedure is more complicated. (2) Hematoxylin-eosin (HE) staining method: This method has good staining transparency and sharp contrast between nucleus and cytoplasm. The dyeing step is simple and stable. It is suitable for smear of sputum. The spleen nucleus is purple blue, the cytoplasm is pale red, and the red blood cells are pale scarlet.
