  • Ultrastructural alterations of the hepatopancreas in Porcellio scaber under stress
    Žnidaršič, Nada, 1970- ; Štrus, Jasna ; Drobne, Damjana
    Cellular ultrastructure varies in accordance with physiological processes, also reflecting responses to environmental stress factors. Ultrastructural changes of the hepatopancreatic cells in the ... terrestrial isopod Porcellio scaber exposed to sublethal concentrations of zinc or cadmium in their food were identified by transmission electron microscopy. The exclusive structural characteristic of the hepatopancreas af animals exposed to metal-dosed food was grain-like electrondense deposits (EDD) observed in the intercellular spaces and in vesieles of B cells. In addition, hepatopancreatic cells of metal-exposed animals displayed non-specific, stressindicating alterations such as cellular disintegration, the reduction of energetic reserves (lipid droplets, glycogen), electron dense cytoplasm, ultrastructural alterations of granular endoplasmic reticulum (GER), the Golgi complex and mitochondria.
