Fig. 9. Histology of the liver. (A) Digesting snake (2 days after feeding) Methacrylate-embedded section of the liver; Methylene Blue/Thionine stain. Scale bar, 50 µm. Note the many lipid droplets (stars) in the hepatocytes. (B) Digesting snake, low-power electron micrograph of hepatocytes loaded with lipid droplets and glycogen deposits. Scale bar, 4 µm. Arrows, glycogen deposits; stars k, lipid droplet. (C) Fasting snake. Methacrylate-embedded section of the liver; Methylene Blue/Thionine stain. Scale bar, 50 µm. (D) Fasting snake, low-power electron micrograph of hepatocytes. Note that no lipid droplets can be seen in the hepatocytes and that glycogen deposits are depleted. Scale bar, 4 µm. Arrows, glycogen deposits; star, lipid droplet. (E) The liver from a group 3 snake (fed once a week). Methacrylate-embedded section of the liver; Methylene Blue/Thionine stain. Scale bar, 50 µm. Star, lipid droplet. (F) Low-power electron micrograph of hepatocytes from a group 3 snake. Histology is intermediate and some lipid droplets can be seen in the hepatocytes together with glycogen deposits. Scale bar, 4 µm; arrows, glycogen deposits; star, lipid droplet.
