==classification of cell==
*renewing cell
*electron microscopy
**0.1 µm thin
==preparation==
*fixation by formalin
**formalin = 37% formaldehyde solution
*delipidation by acetone
*embedding in paraffin
*cut by microtome
==environmental consideration==
*recycle of acetone, xylene
*neutralize formalin
==cytology specimen==
*desquamatory cytology
*scraping -
*aspiration -
*fine needle aspiration -
*stamp -
===fixation in cytology===
*Papanicololaou stain - wet fixation with ethanol
**cells relatively keep their form and size
*Giemsa stain - dry fixation with methanol
**cells are elongated on slide and appeared size is multiplied in 3-4 times than wet fixation
==staining==
===hematoxylin eosine===
*hematoxylin = blue = for DNA/RNA, nucleus
*eosin = red = for proteins
==pathology of infectious diseases==
*extracellular pathogens induce neutrophil-based immune reactions
*intracellular pathogens induce macrophage-based cellular immunity
===abscess and granuloma===
*abscess is defined as aggregation of neutrophils
*granuloma is defined as aggregation of macrophage and/or T-cells
