What is it about?
We analyzed permeability and structure of cell membrane, alveolar membranes and alveoli after treatment with α-amylase, β-amylase, phospholipase C and hyaluronidase.

Why is it important?
Droplets of polycationic dye – ruthenium red – have been trapped within the alveoli whereas the dye was also bound by the outer and inner alveolar membrane. This suggests the presence of anionic sites capable to bind cationic compounds within the alveoli.
Perspectives
Alveolar system in Paramecium is functioning as a barrier – protects the cell against the chemicals added from outside when the cell membrane - separating the cytoplasm from the medium - is impaired.
