Über den einfluß des hydrostatischen druckes auf die ultrastrukturen von zellen und geweben. VI. Reversibilitätsversuche druckinduzierter schädigungen an membranen und mikrotubuli in Zellen mariner Tiere

Gill epithelia of Modiolus modiolus and Mytilus edulis (Baltic and North Seas), and the skin, pharynx and muscles of Branchiostoma lanceolatum (Pallas) have been investigated at the ultrastructural level, employing hydrostatic pressure, to explore the possibility of structural regeneration following decompression. Restoration of all cell structures seems possible to a certain extent, depending on the degree of disintegration and the time period given after decompression. Structural reorganization after release of pressure begins immediately, but no regenerated organelle is comrable with control species, since structural scars remain. Non-reversible destruction to some systems is apparent near the respective LD₅₀-values of the species.
